Hello. This is a challenge for Paolo. I hope you read this, Paolo. You are an interesting human being, you know more about me than what I know about what you know about me, because I have barely talked to you and you, too, have barely talked. Words. Mouths. Saliva. Syllables. Ideas, brain gew, brain stew.

Your challenge is here. Now. You should provide your public ssh-key for repository access through e-mail (heror0 4 8 4 [ a t ] pr ot onmai l.com without spaces it’s just so that the web scrapers don’t catch on to this email. ) . Your task is to edit this article and say anything you want about me. I invite you to write in any language you choose, could be more than one. You can say as little or as much as you’d like. Your preference. I would love to see a story about myself through the eyes of an interested reader of my blog. you may add images, drawings, etcetera. you should make all hyperlinks relative to the data/ directory, e.g. I have an image data/asdf/img and you should reference it in this markdown file in html as asdf/img.

you can preview the whole blog using the make all command from the repo directory. it should run fine in any sane linux machine, just make sure to have the dependencies. Then you can browse the outputted contents in www/index.html . Should you have any trouble, the blog server will deploy every time you push to git. Good luck!

believing in something: Stalker (1979)

Posted on:	01/05/25 22:07:27
Last edited:	01/05/25 22:07:27

I watched Stalker(1979), a Russian film recommended to me by Miranda. It was hard to watch at first, I constantly looking for consistent meaning and then I started contemplating it. That is when I started to appreciate the film.

I watched it in two sittings. In the first sitting my Father was with me, we watched about 30% of the film. Then I watched it the next night and I am writing my review of it just after I’ve watched the film so I don’t forget most of my thoughts.

Spoilers ahead.

I wrote some things in my notebook:

• KEEP GOING! you will end up nowhere!
• DRY TUNNEL
• “I’m fine as I am.”
• “All this is is someone’s idiotic invention, don’t you feel it?”
• The Eternal Jew (???no idea what this means)
• You have to believe

It’s hard to write about this film. I haven’t written an intricate things as this in more than three months I’d say. There’s plenty to say.

The film starts off with a kinda bald guy in his room with his wife and daughter. They are all sleeping on the same bed with the daughter between them. They live in quite poor conditions, their house is extremely near, if not below the traintracks. The sound is loud, clearly loud and the vibrations are not behind. Things will start to move when the train comes and it won’t go away for at least a minute, more like a couple. Then the bald guy starts putting some clothes on, the wife complains about his job, explaining that he should not be doing that. The guy says he has to and leaves. He meets some people, then they plan an escape. An escape to go away from their town to the ZONE. Well, before that they meet at a bar to talk about who they are and they talk a little in the ZONE. I don’t know if it was just me but sometimes it was very complicated to know who was talking, like their mouths didn’t move that much and they did not do any gestures whatsoever and sometimes the shots were too far away for the movements of the mouth to be perceived. Maybe that’s just the doing of Tarkovsky (Andrei Tarkovsky, the director of the film).

Then they escape after using a vehicle with the top off and then they use one of those locomotives that is on the train tracks and choo choo bitch offf they go. There’s a few bullets here and there. No one get’s injured I think. Then they get somewhere. They gotta lose the lil' choo choo thing because that is the way.

The bald guy is the leader. The other’s are there to go to the Room in the Zone. The bald guy has been hired as their guide. He explains to them that they are in the Zone and in the Zone lives no one and the ZONEEEEeee is very special so they gotta be careful about everything they do. Whatever they think is the right way to do things or the right way to go is probably never the first answer, he says. They gotta go the long way if they want to survive. So they take longer than usual. Then one of the guys forgets something, goes for it then is waiting for them with a fucking fogata (fire) with the stuff he had forgotten and then they go and the Writer guy keeps complaining why he always has to go first and then they go into some kind of giant shit hole with water, looks nasty but they do it anyways. They get scared sometimes because of the sounds, then they almost get to the room when the Professor pulls out a fucking bomb and says this Zone, this room has no meaning that no one could ever grant him the inner-most wish he’d want. Ah well I forgot to say the bald guy, the guide tells them that they’ll go in the room and think of their inner-most wish the one that’s really inside of their gut and also to think of their whole lives leading to this point and so they kinda refuse and they go on to rant that this is just some bullshit thing that it has no meaning and they want to bomb the fucking place down because if they don’t like it no one can like and it’s good that they are destroying this guy’s business cause why not. Then they cancel the bomb thing, don’t bomb anything, none of them go into the room for their wish to be granted they return as normal. They see that the bald guy’s daughter can’t walk. The wife says that he married the right guy and some shit that this is destiny and they’re happy. the daughter has some mighty magic and can move stuff like glasses of water n' shit.

*end of movie*

review

At this point I don’t really know what to say. I enjoyed about 70% of the film it has some really good phrases. I watched it in Russian with English subtitles from opensubtitles, maybe there’s a better translation somewhere. I need to watch it again when I’m not depressed of life. I don’t think I felt as if this movie changed my life forever but it did remind me that I have to believe in something, in myself, in someone, in a dream, in ANYTHING! Maybe I’ll update the review

I liked it. Thanks for the recommendation, Miranda.

The end.

March 23, 2023. More than one and a half year later, I am here to write this. I don’t even remember anything of what I was going to write.

Today is now Saturday, January the fourth, 2025!. Yes, 2025. Can u believe it!?!?! I barely can!

Yesterday I went to Mexico City to get a typewriter (yes, those ancient beautiful machines) fixed. I could not find any shops near were I live. The nearest one was in Mexico City.

So I went there. And there it was. A shop. A workshop. Its banner barely said anything about typewriters. The business itself is more tailored to the fixing of printing machines, the newer machines that have become the norm in almost every house with a computer. You have a computer, you are to print. And if you didn’t have a printer at home you wen’t to the stationery store. In Spanish this is a papelería. And I also had with me another machine which I had been almost using daily for about two weeks or so now. And that one worked almost flawlessly. Maybe every 300 characters or so it slightly jammed, it was easy getting it to work again but it did need some cleaning which I am not trusting myself to do but more a professional.

I was with my father and we were in awe as a professional artisan took a look at each and every single one of the compact heavy machines we brought to him. He inspected them, carefully but firmly pressed each key as to see what could possibly be wrong, checked some gears, lever-looking metal things, the roller which rolls the paper after doing a return-carriage.

I hope for them to be ready in a week or so. We’ll see. For now I’ll have to settle writing on my Laptop, a Thinkpad T490. I should name this beast, should you come up with a suitable name please contact me.

I also spent time with my Father as we visited the downtown of Mexico City, near the big government buildings like the Mail Office and the Supreme Court of Justice. We were going to eat in a tavern, a place where you usually drank some kind of alcohol and they served you the food of the day, you got another drink, they served you more food, usually the next course. We were expecting to go to a cantina, canteen, tavern, bar-looking place but no. To our delight we were greeted with a fancy restaurant with extremely nice food. Nice waiters and a lot of history with cloths framed to the walls with fancy signatures, writings, and drawings of famous people. And my Dad and I talked about things, not that much but it was a start. A better start than most I’d say. Than most starts I’ve ever had in my life. I don’t know if I’ll ever have day as beautiful as yesterday. But it was also horrible in some sense. After we ate, I drove us to a tyre shop to the west of Mexico City. After we arrived, my nose started to shut down as it got more and more inflammated (irritated). It got red, it got stuffy, it was harder and harder to breath, sneeze after sneeze, mucus after mucus. Paper, more toilet paper, washing hands a lot. Going to the bathroom a lot as I did not carry any tissue paper with me at the time.

But we also heard some nice tunes I’d say on the way to the tyre shop. I don’t remember which specifically. Nah, I’m lying. I do remember some Radiohead in there, and that’s really all I remember.

I will now cut to the end and leave you in suspense to show how a great storyteller I am (out of ideas).

So that’s that. And hopefully today will be a beautiful day to you to!

Archiving iPhone photo albums without iTunes in Linux

Posted on:	03/28/24 01:55:39
Last edited:	03/28/24 01:55:39

Hello! My Mom asked me to archive the pictures and videos on her iPhone. I tried doing it without iTunes and was somewhat successful! I was able to keep all of her albums!

One knows that iTunes can be a very buggy piece of software. I’ve personally backed up very few times iPhones using iTunes, as I do not really care about having the apps backed up. I only care about the Photos and videos.

It should be as easy as connecting it to your computer, right? Well, no. I mean, kind of. You can easily connect your iPhone to your Windows computer and from your iPhone click on ‘Trust this device’ and it will magically open up the access to your iPhone’s DCIM folder which contains all your pictures.

I’m using Garuda Linux but I’ve been able to mount my iPhone with Arch Linux: https://wiki.archlinux.org/title/IOS

Note: It was a pain in the ass finding the mount point of my iPhone in Garuda Linux. They really didn’t make it easy! Turns out it was in /run/user/1000/kio-fuse-OUJOte/. I could see the files in the file manager, but whenever I right clicked to open a terminal, it would drop me in the home of my root user for some reason.

For those that would like to follow along, the shell I’m using is zsh.

The pictures in DCIM/ have plenty of metadata in there. But the albums are nowhere to be found. I remember looking back a while ago when making a backup of my iPhone and I couldn’t find anything interesting. But today I chose to look further.

And I found an SQLite database! It has a bunch of stuff about Photos. I found it here: /PhotoData/Photos.sqlite.

big big database

or not so big, idk it was like 350 MB

Now, after archiving all the pictures under /DCIM using rsync --archive I manually wrote down the name of each album and the amount of pictures it had. I copied the database to my backup and started looking. I started by making a full dump with sqlite3 Photos.sqlite .dump. And that definitely took a while because for some reason I decided to read the sqlite file directly from the iPhone. I definitely should have copied it over to my hard drive first. Anyways, I started grepping in the dump for the names of the albums and found that the table ZGENERICALBUM is an album description for all the albums. It has the Z_PK column, this corresponds to the Album number, then ZCACHEDCOUNT, which contains the total count of Pictures and Videos in the Album (the sum of ZCACHEDPHOTOSCOUNT and ZCACHEDVIDEOSCOUNT should be ZCACHEDCOUNT); the last relevant column is ZTITLE which you guessed it… is the title for the album.

I also found another table called Z_28ASSETS. This contains a list of the files that are in Albums. It took me a while before realizing the meaning of the fields. I knew the first one was definitely the album number, so Z_28ALBUMS corresponds to the Z_PK field in the Z_GENERICALBUM table. I eventually found out that the field Z_3ASSETS translates to the Z_PK field in the Z_ASSET (yes, “not ASSETS”) table.

Reconstructing the favorites album

But first I found out about the favorites album. This album isn’t located in the ZGENERICALBUM. After all, it isn’t generic. It’s actually located in the ZASSET table. This is actually where all the pictures and videos are. There are even fields with the coordinates of the location where your picture was taken and a ton of other fields from which I don’t really understand their purpose. Anyways, the ZFAVORITE field is in the ZASSET table and if its value is 1, it’s in the favorite album. And there’s also a field called ZDIRECTORY and ZFILENAME and this gives us the exact path to get each picture or video. So all I had to do to get the favorites album was:

sqlite3 Photos.sqlite "SELECT Z_PK,ZDIRECTORY,ZFILENAME FROM ZASSET WHERE ZFAVORITE=1;" > albums.favorites

We can generate the path with:

awk -F '|' '{printf("%s/%s\n", $2, $3)}' < albums.favorites > favorites.unreal

Now, just to rule out any bad pictures, I’ll make sure that they exist by lsing them:

for x in `cat favorites.unreal`;
do
ls ../$x
z=$?
if [ $z -eq 0 ]; then
echo $x >> favorites.real;
fi
done

This is my file structure:

DCIM/
    XYZAPPLE/
    ...
dev/
    Photos.sqlite
albums/
    ...

working directory: dev/

In my case, no files were removed from favorites.unreal. Now that we have the file list in favorites.real, we can make symbolic links in a folder and make that our favorites album:

mkdir -p ../albums/favorites && for x in $(cat favorites.real); do
ln -s ../../$x ../albums/favorites/${x##*/}
done

Note: the ${x##*/} in zsh means anything that matches */ in $x you shall remove. This will basically leave the filename only without the rest of the path (abc/gde/qed -> qed).

Now your favorites folder should be in albums/favorites with all your pictures and videos.

Note: There may appear slightly more pictures than there actually are on your iPhone’s favorites album, there may be some kind of ‘picture deleted’ field that I haven’t found yet.

Reconstructing the other albums

This was pretty hard. As I mentioned before, I knew that the first field Z_28ALBUMS in the Z_28ASSETS table corresponded to the album number but I was unsure of the only other two fields: Z_3ASSETS and Z_FOK_3ASSETS. At first, I thought it was some kind of permutation between the XYZAPPLE and the file itself but that didn’t work out. Eventually I was using sqlitebrowser and sqlite3 at the same time on different tables and saw the exact numbers! I figured out that the field Z_3ASSETS in the table Z_28ASSETS was the same as the field Z_PK in the ZASSET table, the latter of which had the filename. Now it was just a matter of putting everything together.

First, get the albums from sqlite:

sqlite3 Photos.sqlite "SELECT Z_PK, ZCACHEDCOUNT, ZTITLE FROM ZGENERICALBUM WHERE ZCACHEDCOUNT>0 and ZTITLE is not null;" > albums.list

Second, for each album we will create a directory in album/ with the name and album number (apparently, Apple allows for two albums to have the same name so the album number Z_PK is added to differentiate between the two)

awk -F '|' '{printf("../albums/%06d_%s\n", $1, $3)}' < albums.list | xargs --delimiter "\n" mkdir -p

Now we will make another set of album folders to save all the Z_3ASSETS fields that match each album number and then for each album, we will iterate over the file list, get the file name from the ZASSET table and add a symbolic link to the album folder:

mkdir albums_data

awk -F '|' '{printf("albums_data/%d\n", $1)}' < albums.list | xargs --delimiter "\n" mkdir


for x in $(ls albums_data);
do
sqlite3 Photos.sqlite "SELECT Z_28ALBUMS,Z_3ASSETS,Z_FOK_3ASSETS FROM Z_28ASSETS WHERE Z_28ALBUMS is $x" | awk -F '|' '{ printf("%s\n", $2) }' > albums_data/$x/files;
    for file in $(cat albums_data/$x/files);
    do
    sqlite3 Photos.sqlite "SELECT ZDIRECTORY,ZFILENAME FROM ZASSET WHERE Z_PK is $file" | awk -F '|' '{ printf("%s/%s\n", $1, $2) }' | xargs -I .fname ln -s "../../.fname" ../albums/0*?${x}_*/
    done;
done;

done!

If you did everything right, you should have an albums folder with many more directories inside it!

I still haven’t figured out how to rule out ‘deleted’ files, so if you added a picture to an album and then removed it, it will probably appear.

The end.

.ps: info on the database:

TABLE ZASSET contains a lot of columns
column Z_PK         this is the file id
column ZDIRECTORY   this is the location XYZAPPLE/
column ZFILENAME    this is the file name XYZ.{HEIC,JPEG,PNG,MOV}

TABLE Z_28ASSETS contains 3 columns
column Z_28ALBUMS corresponds to the album number to which the file is part of.
column Z_3ASSETS is the identifier that corresponds to the Z_PK field in the Z_ASSET table
column Z_FOK_3ASSETS is something...


TABLE ZGENERICALBUM contains a lot of columns
column Z_PK is the number of the album
column ZCACHEDPHOTOSCOUNT is the photo count of the album
column ZTITLE is the album title

TABLE Z_27ALBUMLISTS idk what's in here

On a bus.

Posted on:	01/26/24 14:34:03
Last edited:	01/26/24 14:34:03

Today, hello. I am writing slightly uncomfortably on a moving bus. It looks small from the back. But it’s indeed a relatively large bus. It is the first time I use one of these tables. There are tables for eight passengers. Always at the back. Are they eight tables? Or just two? They seem to be two. Since on each side of the bus there are four seats, two seats facing another two seats. With a table in the middle. And then there are these little arm/tablerests on top of the big table with hinges attached to it. And they say not to put your arms over it. But that’s really what it’s for. Maybe they mean your full weight or something.

Anyways, apparently there is WiFi. I’ve never used the WiFi on this bus. I like to be out of connection when being on a bus.

Although calls do come in every once in a while. From my parents, mostly. I haven’t written in a big while. My last post must be more than a month old, I think. Esteban read it, thank you Esteban.

Waht to write about? So many thoughts on my mind. The sound is ever-so increasingly loud. Metal banging against plastic, I think. Or maybe metal against metal and some plastic in there. I just feel like this experience is weird.

There’s a movie playing on the bus with the (probably main) character being played by the guy who is in many Wes Anderson movies. With an oval face. There’s a guy with a Macintosh sitting near me. He is in the section with tables. He’s on the left side of the bus. But he’s the closest one to the aisle. I’m also next to the aisle, but on the right side of the bus and sitting at the back. He’s sitting one seat before the back.

I think this is the first time in a while that I don’t sleep on a bus. It has been a while. I remembered it quieter. I believe the transmission and motor stuff are just more audible in the back of the bus than say, the front.

This is a good start. end for now.

El Teatro ó El Teatro y Yo.

Lunes 16 de octubre de 2023. Acrerca de: El Teatro ó El Teatro y Yo. Título: aún no decidido.

El Teatro. El Teatro es algo. No es alguien. No es una persona. Podría ser varias ideas. No creo que sea una sola idea. Puede ser muchas cosas, claramente. Puede ser bailar, cantar, actuar. Verse a los ojos en un escenario. O también en la calle. No hay que estar tan alto en un bloque de madera o viendo a lo lejos desde unas butacas incómodas para decir que vivimos el teatro. El teatro es una manera de contar historias. Sí, ya sé. Hay muchas maneras de contar historias. Pero el teatro es más personal. Es en vivo. Hay personas frente a frente. Hay butcas, sillas. Un escenario de madera que a veces rechina. La acción sucede ahí mismo. Y sólo lo presenciarás una vez. Podrás ir a ver una obra del mismo director, mismos actores, mismo todo, una y otra y otra y otra vez. Pero nunca será lo mismo. La hora no será la misma. Probablemente el día tampoco. Los actores idealmente estarán pensando en básicamente nada y sólo serán quien tengan que ser. Porque ser un actor se trata de comprender una escena, se trata de ser quien tienes que ser. Tienes que vivir y sólo ser. Sí, sí estás pensando. Pero estás pensando como todos los días, siendo quien tengas que ser.

El teatro puede ser esto:

Oh, Hanna. How I’d like to meet you is… i don’t know. Yeah, I like you, sure. You’re beautiful. I’ve heard you’ve got a boyfriend. Fine, I won’t try to ask you out. Yet, I still want to meet you. Wouldn’t you? Don’t you? I wanna meet you. Know who you are. Know why the fuck do we stare at each other. Maybe we wonder too much about what could be, instead of doing whatever it is we wanna do, you know? I wanna give you a kiss, just for fun. But alright, I won’t, I know you’ve got a boyfriend so I won’t try to do that. But you see, the obsession is not with being your boyfriend. It’s with getting to know you. Know what’s going on in your mind, understanding how you can achieve such beauty.

I wanna ask you if I, me, myself, ever happens to cross around your mind, If you ever wonder about me, if I create, if any, importance within you.

Fin.

Life before your eyes

Hopefully it is not a tragedy. I am rebooting my server after more than 374 days of uptime. Not complete uptime, since sometimes I do reboot the webserver command (lighttpd) every once in a while. But in fact, this computer has been alive, consuming some amount of electricity, power, work from somewhere else, for the last 6 minutes, 21 hours, nine days, and one full year as of writing this. In a few minutes time, power will be cutoff for a few seconds, and then, back to business!

But what is it with computers and rebooting, that we must do it all the time. It feels kind of essential. We’ve built this persistence around memory, hard disks, solid-state drives. The files will be there, intact, thanks to the error-correction built-in to file systems and physical devices. Pretty weird, right? That you can kill all the power, turn on again and it will work almost exactly the same as before. Or maybe your error will be fixed, because of some weird condition in the code that specifically made it act that way.

Oh, computers, persistence is key. But the persistence of the reboot is there. It has stood time. It is still advisable to reboot your computer. To turn it on and off and see if it works. Or just for the good of the device, right? I always turn off my computer when I am not using it. Even if I will use it in 30 minutes, I will turn it off. I’ve been told to do that. Some people like my sister do not. She leaves it on ‘suspend’. She just closes the lid and lets it be. Some other people do to. I’ve seen it with my own eyes. Is it bad? It’s their device after all, not mine. Their decision. I am unsure if it’s actually better or worse, I feel the latter.

But you see, this uptime, this little huge number (about 32,390,084 seconds) has been there, coexisting in time. It’s the longest any of my property has stayed on, as far as a I now. It’s the only computer I own that has stayed on for that long! I even have the uptime advertised on my curriculum vitae. Yes, my CV! here: https://cv.thetrevor.tech. Actually, the last time the uptime of my server was recorded was on Agusut the 16th at 10:43:02 CDT 2023. That was an uptime of a little more than 365 days, almost exactly a year! Very weird thing to discover. And when I reboot, will it all go to doom? I sure hope not, since I am not where my server is.

My server is far, far away. Slightly less than 100 miles from me. Should it not wake back up, what should I do? Well, I’ve done this before, I will not lie. I’ve talked to people near the server, to see if they can fix it. They have indeed fixed it. Thank you.

But I want it to spring back to life. On its own. It should connect to the network automatically, exposing its ports (80 and 443) to the world, not giving a worry about anything, and really Just Workin'!

I hope you really do work. This will be the last upload with a very big uptime of 374 days and a little more time.

Alright, see you on the other side!

Cálculo Lambda

Posted on:	05/10/23 00:42:09
Last edited:	05/10/23 01:13:50

Imagen de Universidad de Princeton (s.f.)

Alonzo Church nació el 14 de junio de 1903, en Washington, D.C. Su padre fue un juez. Estudió en la Universidad de Princeton y obtuvo una Licenciatura en Matemáticas. Se graduó en 1924 y pasó a obtener un doctorado en los próximos tres años bajo Oswald Veblen.

Fue maestro de filosofía y matemáticas por casi cuarenta años. Dentro de sus trabajos notables, se encuentra su desmostración al problema Entscheidungsproblem, desarrollado independientemente de Alan Turing y en donde llegaron a la misma conclusión. Se destaca por haber inventado el Cálculo Lambda, un sistema de notación para funciones y sus aplicaciones. Church fue el asesor de tesis de Alan Turing, también en la universidad de Princeton.

1. Introducción

El Cálculo Lambda es un Sistema Formal que busca definir una notación para funciones y sus aplicaciones. Fue desarrollado durante el siglo XX.

El Cálculo Lambda pretende definir un modelo que utilice la abstracción pura para definir funciones y aplicar las mismas, definiendo objetos primitivos para poder realizar generalizaciones.

Ha sido la base para muchos lenguajes de programación de tipo funcionales, incluyendo CommonLISP, Scala, entre otros. Asimismo, el concepto de los lenguajes funcionales se deriva, en parte, de las investigaciones de Church y otros matemáticos. Los lenguajes funcionales ofrecen un nuevo paradigma para observar, modelar y diseñar algoritmos.

Esta investigación busca ofrecer una introducción al Cálculo Lambda a través de varias perspectivas, incluyendo un análisis de la Teoría desarrollada por Church, así como los usos dentro de las Ciencias de la Computación, sus diferencias con otros lenguajes de programación y usos dentro de las Matemáticas.

2. ¿Qué es una Función?

Una función, también llamada transformación u operación, es una regla de correspondencia por la cual se obtienen valores a través de argumentos. Es decir, le proveemos a una función un argumento (también referido como un valor de entrada[1]) y obtenemos el valor de la función para ese argumento (también referido como valor de salida[1]).

Para estas llamadas funciones no necesitamos utilizar todos los posibles valores dentro de los números, sino que podemos definir la existencia de nuestra función sólo bajo cierto rango de valores para los que nuestra función será válida. Cuando la función sea aplicada con un argumento cuyo valor no coincida dentro del rango especificado, se podrá decir que no tiene sentido aplicar la función con ese argumento.

Para el Cálculo Lambda, se utiliza una noción de la aplicabilidad de una función de una manera más abierta. Normalmente, no se permitiría utilizar dentro de una función f como argumento la misma función f. El Cálculo Lambda define teoremas de consistencia que permitirán que esta noción sea válida para este sistema formal (Church, 1941).

3. Abstracción

La abstracción se refiere a la generalización de problemas para poder obtener soluciones generales a un problema en específico. Estas generalizaciones de problemas se derivan de problemas concretos y después se empiezan a sustituir los objetos concretos por nombres, para así generalizar las instancias de estos objetos concretos, convirtiéndose en instancias generalizadas y obteniendo así soluciones generales.

Ejemplo de un problema concreto:

Ejemplo 1:

Considere que quiere comprar 9 productos a 10 pesos cada uno.

La fórmula para el costo total es:

En el Ejemplo 1., se realiza una operación concreta de la multiplicación en los valores concretos 10 y 9. Para obtener una solución general al problema, se abstrae el número de productos y el precio por cada producto.

Ejemplo 2:

Considere que quiere comprar 5 productos a 10 pesos cada uno.

La fórmula para el costo total es:

Ahora, se puede utilizar la fórmula del Ejemplo 2. para evaluar un problema con diferentes valores y no se depende en valores específicos para explicar la solución a un problema general.

Se puede decir que la abstracción está completa pero también se puede volver a abstraer de nuevo extrayendo la operación que se realiza a los números, es decir, el signo de multiplicación: *. Se deja como ejercicio al lector el crear una fórmula que permita cambiar de operación (como división, multiplicación, etcétera). Evidentemente, la nueva fórmula respondería a un problema general mayor y no solamente al problema general de obtener el costo total.

“La Abstracción se basa en la generalización a través de la introducción de un nombre para reemplazar un valor y especialización a través del reemplazo de un nombre con otro valor.” (Michaelson, 1989)

4. Escribiendo Cálculo Lambda

Escribir Cálculo Lambda[2] bajo la sintaxis que Church diseñó permite tener un sistema formal en donde si no coincide con el sintaxis no será un término lambda correcto. Cualquier término que esté sintácticamente correcto será válido en el sistema formal de Cálculo Lambda[2].

Los símbolos primitivos que se utilizan son:

Léase como “lambda, paréntesis abierto, paréntesis cerrado”.

También se utilizan una cantidad de símbolos infinitos llamados variables:

Se recomienda utilizar las letras del abecedario.

Los términos-λ (léase términos lambda) se definen inductivamente:

• toda variable es un término-λ válido
• término-λ de aplicación: si M y N son términos-λ, entonces también lo es ( M N )
• término-λ de abstracción: si M es un término-λ y z es una variable, entonces ( λz[M] ) un término-λ

(Stanford Encyclopedia of Philosophy, 2021)

8. Notación Alternativa

Al hacer investigaciones acerca del Cálculo Lambda, se pueden encontrar diferentes notaciones. Church propuso diferentes sintaxis para definir el Cálculo Lambda. Las siguientes expresiones son equivalentes:

Para estas expresiones, el uso de paréntesis es opcional e incluso al aplicar una función no se necesitan paréntesis en algunos casos pero sí se pueden utilizar para tener una notación más explícita.

Church utilizó corchetes[3] en artículos anteriores como “An Unsolvable Problem of Number Theory” (1936) y “A Set of Postulates for the Foundation of Logic” (1932). Sin embargo, él recalca en “The Calculi of Lambda-Conversion” (1941) que los corchetes[3] se pueden reemplazar con puntos, de tal manera que el punto reemplaza directamente al corchete abierto y el corchete cerrado se elimina por completo.

How to get a consistent RSS feed ?

Posted on:	04/19/23 16:33:16
Last edited:	04/19/23 16:33:16

It’s hard. Well, maybe not that hard. But when you coded a half-assed program to generate an RSS feed using shell scripting inside a makefile it’s gonna be pretty hard to fix it.

I’m most likely going to rewrite all the RSS feed generator in C. I hope that doesn’t bring any more problems…

Well, it all began when one of my readers told me that he was attempting to use the RSS feed and told me that it was broken. He didn’t explain much else beyond that, aside from the fact that the atom link was broken too.

And by broken, he meant that it wasn’t being properly parsed. But the atom link just has been broken for a while - because the file doesn’t exist on purpose. I’ve been meaning to fix both, the RSS and the Atom feeds which are very similar but just haven’t had the will to do it, until now apparently. I hope this will lasts long enough that I am able to fix both problems.

Well, onto the story. So I replied back to him, thinking if I should even reply. Should I reply right now saying the problem has been acknowledged and I’ll try to fix it or email him when it’s fixed !? I don’t know. Well, I replied anyway, saying that the RSS generator was probably doing something wrong and that caused the parsing in his RSS feed to not work. I mean, just opening the file in chromium- a web browser- yielded a parsing error.

Turns out, the error was in the title of one of my blog posts. It had two </em> tags, literally. Notice that </em> is the closing tag of <em> but turns out I forgot to write the opening <em> tag in the title. I wanted a part my title to show up in italics so that’s what I thought I wrote in, one <em> and then one </em> tag. But I wrote just two </em> instead. So the only thing I had to do was remove one single slash character /, add the file to staging through git with git add file, commit and push to my server. Then wait for the blog to be generated. Because it’s not HTML. It’s markdown and it has to be parsed first into html. Then the RSS feed is generated and so on.

I waited for it to finish, it took a minute and a half or so. Now I checked again and there it was, without no error in chromium. Showing the ugly XML file. Then I put in the RSS url into a free RSS viewer [0] and it worked! It really worked.

I was very proud of that. To be fair, I only found out about that wrong </em because the chromium browser said error parsing at line something column something. Still, that was fast debugging.

step 1 of making a better RSS feed

probably, code in something that removes all html special characters such as html tags and replaces them with nothing. Or maybe its markdown equivalent. e.g. replace <em> bla bla </em> with _ bla bla _ and so on.

That’s easy enough I guess, I’ll do it later today maybe. I’m still unsure of what I’m going to code or how I should fix the whole RSS feed generator thing. I’m unsure if it should all go into one program. or if I should outsource some tasks to the makefile that in turn, uses the git command to get important things such as the date, file name, link, etc. Maybe I should follow the UNIX way. Your program should do the following: Do one thing and do it well Maybe I should have several tiny programs that help me and then pipe them together. I think that sounds nice.

Please share your thoughts!

High on happiness

Posted on:	03/29/23 00:40:57
Last edited:	03/29/23 00:40:57

When do you ever, truly, feel happy ?

I think that’s when your willingness to live to survive, increases. When you wanna feel alive you wanna just keep on living and you’re so fucking high on adrenaline you just feel like you wanna keep going.

That’s what I felt like whilst watching Uncut Gems. A movie with Adam Sandler. It’s about a guy who deals jewelry, all kinds of things. Fancy, big things. He’s jewish.

so he gets this rock. And the guy’s a gambler, like a real fucking gambler. He gambles his money at work. He owes debt to a ton shit of guys. Even one of his family members. And one of his family even makes Adam Sandler get beat up cause he stills owes money.

And you know, the plot realy doesn’t matter that much. Well, no, it does, it did to me!

Really, what this film is about. It’s about the unexpected. About life itself, you never really know what you’re gonna get. You don’t know if all your dreams are gonna come true no matter how hard you work how hard you put in the hours. Sometimes, it just doesn’t work out. At all. That’s what this movie felt like. And all of a sudden, when you feel like really everything is fucking falling apart, you get this feeling of salvation.

Someone’s coming for you. Someone’s giving you back your willingness to survive, to live, to love, to enjoy. And you take it. And you win.

This movie reminded me of a quote from the show “Rick and Morty”, Rick says:

“To live, is to risk it all.
Otherwise you’re just an inert
chunk of randomly assembled molecules
drifting wherever the universe
blows you.”

- Rick Sanchez (from the show Rick and Morty)

And you see, I just saw below this quote another quote, an interesting one, which really resonates with the overall theme of the movie:

Money will not make you happy,
and happy will not make you money.

Don’t know who said it, but someone did.

And really the movie all is about money, or addiction maybe, or even just obsession over something. This guy just feels like money will solve everything. In reality, it won’t at all solve any of his problems with his family or friends. It will only solve what is immediately bugging him, and that is that he’s in deep debt with some people in the jewelry business.

He’s in some much debt that they keep coming to his family events, to the school of his kids. They strip him naked and get him locked in his car’s trunk. Very fucked up. And don’t get me wrong, the guy is kind of an asshole. He went out lending money and betting it.

But you see, his bet was right. But the guy who lent the money to him heard that he was betting all he lent and got the broker to call off the bet. Just like that.

And it is of course depressing, that even after ‘hard’ work effort, sometimes you get nothing. Nothingness.

This movie gave me the real feels. To be on the verge of losing it all and suddenly gaining it back and winning at life. I feel like if I’m not risking anything at all in life, daily things really, then I’m not gaining anything.

You may feel like you’re risking your hard work, your sanity when you’re at school and after all you’re betting that you’ll be super fucking intelligent and you’ll be happy.

But you see my man, my ego is fucking high. I get all kinds of people, well I don’t get them to do this. But my friends understand that I’m smart, I’m intelligent.

My college degree, right now I’m not doing shit for it. I’m barely passing, I’m lazy. Because school right now bores me. I’m barely risking anything. Well, I’m risking maybe failing one subject this semester but it’s not like my parent’s can’t fucking pay the subject again. They can but I’m just not motivated enough.

You see, if I’m not motivated properly I don’t do things. I want all that pressure to come down on me. I want to feel like my body’s about to explode if I don’t do something. And when I do it, I win. All that pressure comes off and I get to experience happiness. And everybody’s proud of everybody because in the end it worked. It doesn’t matter if in the past we were all lazy or whatever or if we didn’t work hard enough. None of that matters in that moment. What matters is the now, what you just did and what is happening right at this very moment and that is in one word, success.

That’s what I felt on this movie.

Thanks for your attention.

Escribo aquí, ahora, porque puedo y lo he decidido. El día de hoy me levanté alrededor de las 8:25 horas de la mañana. La noche anterior comí mucho. Salí alrededor de las siete u ocho de la noche por elotes. Fui con mis amigos a un estacionamiento con un ‘food truck’ como se le conoce en los Estados Unidos de América. En español de México también le decimos así. No he escuchado la expresión ‘un camión de comida’. Así que así se quedará. Bueno, el punto es que en este puesto venden elote. Ni siquiera elote en vaso, esquite o trolelote (al menos no lo vi anunciado). No. Sólo elote con un palo. Se le pone queso, mayonesa, salda. De todo. También vendían un tostielote - justo lo que pedí. Es una bolsa de papas de tu elección (doritos, tostitos, entre otros) y le ponen, efectivamente, elote y salsa, queso, todo eso lindo y querido. Y también vendían panqué y pastel de elote. Yo pedí una rebanada de pastel de elote. El panqué sabía casi igual - lo probé de un amigo. Nos gustó. Está cerca de donde vivo. Unos amigos ya habían venido a este lugar y nos invitaron. De hecho nos fuimos en un sólo coche. Un poco encimados. Bueno, bastante realmente.

De regreso algunos amigos quisieron comprar en un súper así que no estuvo para nada apretado. Para hacerles el cuento largo, cuando llegamos jugué ping pong con el amigo que nos trajo. Estuvimos retando por una media hora, tal vez una. Después se fue y llegaron otros amigos que viven cerca. Decidimos cenar juntos. Cenamos pollo frito, de KFC. Lo pedimos a través de Rappi. Salió un tanto, bueno, bastante caro. Alrededor de $170 pesos mexicanos por persona. ¡Sí, en serio! Éramos cuatro (4) personas. Pedimos un combo pero me imagino que rappi o el propio restaurante infló los precios.

Bueno, también pedimos el modo de envío rápido o “prioridad” por diez (10) pesos más. Sí, sólo diez pesos. Al final tardó una media hora en llegar el pedido. Parece ser que el repartidor estuvo un ratote esperando el pedido. Me imagino que en un jueves por la noche estaba bastante ocupado el restaurante.

Como decía, cené mucho la noche anterior. Me cómí cuatro piezas de pollo. Muy rico y grasoso. Pollo frito / empanizado. Un amigo extranjero dice que está mucho más rico el KFC aquí en México que allá en su país.

Me empecé a bañar esa mañana. Me tardé unos 20 minutos, un poco menos tal vez y después me tardé algo arreglándome para un taller, clase de batería - el instrumento musical. Era mi primera clase. Llegué unos cinco minutos tarde. Me presenté con el profesor. Me gustó la clase. Es una clase individual. Nunca he tenido una clase individual de música. Practicamos ritmos. No me acuerdo de lo que me enseñó una vez mi querido amigos. Sin embargo, recuerdo que me divertí mucho.

Después me encontré a un amigo. Desayunamos juntos. No había tenido tiempo de desayunar antes de mi clase. Hicimos una tarea juntos, nos tomó un buen rato. Estaba exhausto. Decidí ir a mi apartamento. Estuve en mi celular una gran parte. Fui al baño. Tomé agua. Tenía hambre pero no sabía dónde comer. Decididí ir a una tienda de instrumentos musicales a comprar unas baquetas. Pensé que me costarían mucho más dinero. Después fui a comer tres tacos mixiote en un lugar cercano de la tienda.

Empecé a merodear y caminar por doquier. Encontré un parque. Encontré un segundo parque. Este segundo parque está raro. Me recordó a alguien, una mujer. El parque está lleno de Ninfas. Son criaturas mitológicas en forma de mujeres jóvenes desnudas en medio de paisajes luminosos. Esto según un diccionario. Les cuento esta historia desde este mismo parque. Hay muchas esculturas de mujeres desnudas. Son de algún metal. Hay una como si quisiera alcanzar el sol, las estrellas, como si estuviera pecando, a punto de agarrar la manzana de un árbol. La estatua está directamente bajo un árbol, estirándose.

No lo sé, las mujeres son raras. Son hermosas y complejas a la vez. Pueden ser inteligentes, son humanas después de todo. Tal vez le debería de hablar a esa mujer, ¿no?. Muchas culturas actuales tienen problemas para hablar con mujeres atractivas, incluido yo. Especialmente los hombres. A veces lo vemos como un trofeo. Yo intento sentirlo como una experiencia para conocer a una nueva persona, escuchar sus historias, compartir las mías y transmitir conocimiento. Son muy diferentes a los hombres. Cuando yo conozco a una mujer, mi corazón , mi mente se llenan de muchas cosas, sentimientos primitivos tal vez, de atracción sentimental, a veces sexual. Pero no sé. Las mujeres me hacen reflexionar de mi vida.

Todavía no sé todo lo que quiero decir con esto de las mujeres. Tal vez me esté enamorando de una. Nunca sabré con certeza todo lo que quiero decir, pues nuestra mente pasa por tantos pensamientos a la vez que se van perdiendo y olvidando inconscientemente. Incluso algunas veces, al estar transcribiendo mis escritos, me doy cuenta que mi entendimiento de lo que alguna vez escribí en el pasado también se puede olvidar. Mi letra va cambiando y con eso mi significado, a veces no descifro palabras que escribí.

Fin.

Hello, world!

What am i doing here? what am i doing now ? i do not really know. i can tell that i am writing. i am writing on a text editor, on vim, on an operating system called linux.

but how do i feel? because for some reason i keep thinking and thinking and thinking. but sometimes none of that thinking sticks.

i think too much. i am a person with ideas that flow. i am not directing those ideas anywhere, really. why don’t i?

i don’t know, i am unsure. i am writing to remind myself that i used to do this, write. I used to write on my blog.

maybe someone will read it, maybe someone will not. i also want to remind myself this blod, it is a record of some of my thoughts and should act as an archive of my mind. of the structure of it. or maybe not at all. some articles are highly edited, some are just written as i’m thinking about them. varies by a lot.

anyways, there’s some people i’ve met. in these short two weeks i’ve met tons of people. maybe my expectations were too high and i expected people with too much of me, with too much of my breed.

but i’ve learned that there’s variety. i’ve met people. hopefully someone reads this and finds meaning in some of the thoughts said herein (is this the right fancy way to use this word?).

I dropped out of university. I was majoring for CS Engineering (Ingeniería en Tecnologías Computacionales) at Tec de Monterrey Campus Toluca.

I didn’t like it there. I mean, I did but I felt like I wasn’t learning. Plus, I was there for three years during high school. Not exactly the same building, but the same place. This might sound kind of dumb, but I wasn’t learning much from my programming classes. And my engineering classes could have been better. I felt like I wasn’t grasping the concepts necessary to understand physics, I felt like I was rushing.

I felt like I needed a change.

So I dropped out of there and I’ve decided I’m going to Puebla. It’s a three and a half hour drive from where I currently live. I will be studying at UDLAP. that’s short for Universidad de las Américas Puebla. I will be studying the same thing. Here it is called Ingeniería en Sistemas Computacionales. Or Computer Science Engineering, I think.

Anyways, I will be starting classes on January 9th, 2023. I’ll be staying at the university’s dorms.

Hello, world!

You know, there was a big gap of history and life between this post and the post before it: Not on the melancholy hill. I guess I could say that I honestly felt like shit between those two times but I don’t really feel like doing that. What i feel like doing is telling a story. A story of now, of a recent now. Not a yesterday but of today. Of what I did for me and for others the day of today. That’s right, not the morrow (yes it’s an actual word look it up), not the yesterday but today. What happened today and maybe what will and what i want to happen.

a new beginning

(not-so) So yeah, a not so new beginning. I had three alarms set for today. One at exactly 06:59, another one at 07:00, another one at 07:01. That was it. This was the day I was actually going to shower fucking early, have the time of my life and get to my exam on time and maybe study and chat with my friends. But you know what ? You know what ? Laziness got me!

Damn laziness got me !!! I didn’t get up. I kept looking at the time. Ok, 07:01. Should I get up now ? Nah, it’s too early! Let’s keep sleeping ! Eventually, my mom said hello and told me to get up. I tried, I hugged her. I kinda got up. Then I fell asleep. Again. and Again and again.

I tried getting up. I looked at my phone constantly. I was sleepy but I was waking up at approximate intervals of five minutes and looked at my phone and said “it’s too eary to get up and shower, let’s sleep more.”. Until I kinda overslept and I showered at 08:00. I was supposed to be eating and making breakfast by 08:00. A little embarassing for myself. But then I relaxed because what’s the worst that would happen ? That i’d arrive late to school ? Wow, what a naughty irresponsible boy who misses class and arrives late late late! what a bad boy !

Well yeah, call me an ass or whatever. Sometimes that’s me. And that day it was. My sister was also hoping to get early but at the end we both did things that made us late and we don’t blame each other really, it just happens. Constantly kinda which is bad and we should work on it. But hey that’s life. Anyways, I got to breakfast. I was already pretty late. I exited the bathroom and it was like 08:25. So I tried to dry the water off my head with the towel. I don’t like hair dryers. They make too much noise. It boggles me. maybe there’s a better translation for the Spanish word aturdir. So I put on some clothes, tried to make it fast. Tried to gather all my shit. Then headed down to the kitchen. It was late indeed so I thought of an easy breakfast. That took me like two minutes probably. Just to think of it for some reason.

So i decided to make a peanut butter jelly sandwich. Peanut Butter. Jelly. Bread. PBJ Sandiwch. PJ Sandwich. that’s it. That was it. I also ate an apple. A whole apple. While the bread was toasting I thought of going to my bathroom to wash my teeth because I sure as hell wasn’t going to finish that sandwich at my home.

So I went off to wash my teeth. Then I headed down and got to work on my sandwich. I had a bread lid and a normal bread thingy. I thought about what to put on each. Since it would be peanut butter and jelly. I do one side for each. But the lid has much less surface area. Or at least less apparent surface area. And it is curved. I thought of putting more peanut butter jelly so i went for the normal bread slice and then put the jelly on the bread lid. Then I smashed them together and tadaaa we have a fucking peanut butter jelly sandwich, right!?

Ok yeah let’s go! And off I went with my sister! She drove. I wanted her to drive because I just wasn’t feeling like driving. I feel like I drive bad sometimes and this was just a signal to not drive today I guess.

And my sister asked me to read something for her. Some bullshit reading about hacktivism in Mexico ? I barely read a page and the abstract. It was fine but too scientifically journalistic for me. Cut the bullshit, get to the chase.

Stop trying to re-define terms and actually say something of importance. No one wants to read a distilled shit-tasting article without any written substance. It’s gotta tell a story! Everything has to tell a story! This was storyless. Technical reading, storyless. Not so interesting.

yet it still intrigued me so I sent it to my phone since I was reading from my sister’s phone. Then we arrived. My sister had to get to class - I did to but who cares - so I took the car and parked it all the way to disney (that’s what we call the far end of the parking lot). And then I got to class.

We worked on modelling projectile motion from rocks that are launched from a volcano with variable angle and air density and velocity of course! And it worked pretty nicely, I understood the formulas. I am proud of that code.

And we ordered it with functions and shit and used one single for loop and structured everything so that we don’t forget what the actual fuck the code does and yes. I am proud of doing that with my friends.

We had some hiccups here and there but our teacher came to the rescue and our mistake was that we were trying to access a vector value where there wasn’t even a vector and for some reason the matlab interpreter doesn’t give a fuck and just errors out once it sees it! Another bad thing about non-compiled languages - I think.

After that I had a bite of my sandwich. Then I went to the bathroom because I wanted to poop real bad. And of course the bathrooms are full of shit, they either smell like shit or they work like shit! I really wish that no one made automatic bathrooms ! Really, it doesn’t do any good.

The sensors aren’t well made or well calibrated. I constantly get bathrooms that are always flushing when I sit down. I physically have to touch and leave my palm on the sensor for it to stop. That’s really annoying. And then how am I supposed to clean myself while doing that ? The position that I’m in is very uncomfortable with one arm twisted in opposite direction of where I’m looking and another hand to clean ? That’s bad, very uncomfortable.

And then I kinda get shame. Because some guys make fun of people because the bathroom just keeps flushing ! It really does ! I’m not making a prank, I’m not filling the toilet up with toilet paper and making it flood. No, I’m actually using a bathroom for what it was meant to be but not it has to be me who gets the always-flushing-bathrooms (trademark pending!)!!!

AAAhhh. anyways, this takes a while. maybe 10 minutes. Then I head back to class. Technically the same class but this class is over because the first two hours it’s with one teacher and the next two is with another one. With this other teacher we’re having a physics exam!! Ahhh, for some reason people say i’m his favorite but i’m ashamed because I barely get any knowledge from the class. I don’t understand. Some people say it’s the teacher. some days i am inspired to take in knowledge and i keep making questions and i get the answers right but others like today like in this exam i was unable to answer my own questions. And even though I asked the teacher I still wouldn’t get it. I mean, after all it’s my mind who has to get it. Right ? Who on earth has to get this knowledge more than anyone in order to get a passing grade on the subject ? Well, me, of course.

So it didn’t really go well in the exam, alright ?

Yeah, the end. Oh no wait I’m gonna tell more because why not.

So I turned in the exam. Only three questions. But it was digital, so I couldn’t go back to see or choose my previous answer or question.

I had to do one by one. I was getting tired and I kinda re-did each question twice but still wouldn’t get the answer. It was multiple-choice and my answer wasn’t there! So I just kept on going to the next one. Did i say it was only three questions ? That’s too little i guess. Or too much. Don’t know.

Anyways, the class isn’t even over but I turn it in like 35 minutes early. We had like two hours to turn it in. I didn’t want to fuck with my mind. If i don’t know something, I don’t know it so I acknowledge it. I’m not goning to keep on fucking with my mind and drilling into it until I get an answer I don’t understand. I’m not gonna do that. At least not today.

So I give up i turn it in 35 minutes early and I finish that peanut butter jelly sandwich because really I only had like four bytes max. I go into the sun I sit on a weird-angled bench and i finish eating it. I’m about to smear my face mask with some jelly so I put the mask aside so that I don’t dirty it up. I finish eating. I like what I’m eating. I like the sun. I enjoy the sun. Then I go to walk around. Then I try doing some exercises but I don’t really get these exercises that are on a web platform and the explanation is pretty bad. Later in the day one question will be solved with the help of a good friend who actually explained to me what the fuck was going on ? or maybe i made too many quesitons idk but thanks for helping me, Alice. Anyways, I try to continue on but actually I have like 70 emails in my student email inbox so I try clearing them. Most of them is spam of international programs, events that I don’t really care about. They literally re-send the shit just not giving a shit. It’s practically spam. Oh yeah and did I mention those were just like in three days ? Three days of OFFICIAL spam email. So fucking annoying.

Anyways I finish up. Now I go to eat. It’s 14:00 by now. that’s two o'clock. I go to the cafeteria. To eat well, because I should eat well. And I have class at 15:00 (three o'clock). And I find a friend. Actually, two friends. i salute each. I eat with one of them. can you guess who ? I meet some people. i forgot their names. i don’t know why.

anyways, I try to talk to them, socialize. I try, I try. I kinda succeed. I don’t feel bad about myself so that’s good. Then i finish eating. shit i was supposed to give office hours to a guy about programming. to tutor him basically because I don’t have an official course this guy is taking or something. I’m not a paid teacher but I know programming and he was looking to get some explanation to a problem. But i was still eating. the situation was unfortunate. We didn’t even meet. it was too late. i was kinda late for my class. I could have taken longer and met with the guy because my class always starts late but for some reason i wanted to get there early. Anyways, we reschedule. Hopefully no one dies.

And so my class at 15:00 begins. Boring, boring boring. Videos about cells. Sleep. Kinda wake up. Rocking my neck up and down. Rocking it fast up because I wake up. I cannot find a stable position on which to sleep. That is annoying. The teacher calls my name. Not me but she says my name but wait it is actually me. Am i supposed to wake up ? I’m sleeping I think she’s looking at me. Oh shit i’m awake now. awkward thinking.

anyways she still keeps talking. goes on with the class. class ends. ta-da. i go to walk. i meet with some friends. I talk a little more. now this is were a friend helps me with the homework and tells me to meet them somewhere because right now i’m with other friends. so i say goodbye and i go to look for the friend who’s helping me out with this assignment and i take a while, really. i couldn’t find her until i did, i guess. right ?

anyways, she tutors me, we talk a little here and there about life. enjoyable. then she leaves, i stay trying to solve the next question but i get stuck. i kinda give up. I send an email to my teacher asking for some office hours and asking for him for an extension of the assignment. He does not respond. then i call my sister. My sister is in the car. I want to leave. but she’s on-campus and she’s moving the car closer. So i tell her not to leave the car so that the engine keeps running but she does in fact turn off the engine because why not i guess ? then she starts looking for some stuff in the passenger seat. She takes a while. I want to leave. I’m awkwardly standing there. She eventually finds whatever she’s looking for and I leave. We say goodbye.

We shall meet again, sibling.

And then I get home and I drink some water. I was going to watch netflix but lo and behold my teacher has spoken. he can do office hours now. that was 10 minutes ago that email was received. I suppose i can still make it. ok, i set up the virtual meeting and off we go. he does in fact connect like five minutes after i send out the email (probably less) and well that was pretty fast. he clears up some doubts well i think i cleared them on as i was saying them. I guess so ? Maybe he felt bad of not explaining full-on to me. maybe. maybe not. as i was saying the doubts they cleared up in my head so that was good. and then cool . finish. finish meeting. finish meet. finish exercises. finish more exercises. continue exercises. why isn’t this working. meet mom. mom arrived. talk to mom whilst doing exercises. pay some attention to mom. talk to mom. go back to exercises. keep talking to mom while doing some exercises. and maybe i’ve written too much.

good bye.

the end.

and well not really hahah.

After that my mom realized that i was kinda busy so she told me ok finish up there with your exercises you seem like a responsible person for this single instance of time so why not let you be right now. so i finish up on those exercises. i feel good about myself. I start watching youtube. i find an interesting video on calculus. kinda boring the last quarter but hey i expected something different not that bad eh. then i think of writing this and hopefully i finish writing this ‘today’ blog post and i publish it. the end;

For some strange fucking reason, I feel satisfied. I am not sad. I feel like I’ve done enough of a purpose to myself and society and to my family. At least for today. I’ve talked to friends, maybe not as much as I like but whatever.

Today I drove. A lot. I drove in highways, strange fucking race-car-like roads that are technically in the state where I live !

I liked driving. I went to one of my dad’s friends from work apartment with my mom and dad, we were invited to a dinner. He lives in some kind of a paradise. There’s a supermarket in his gated community ! It’s gigantic ! There’s so many houses surrounded by the woods. Looks like a lotta rich people live there.

Not necessarily high-class rich people but middle-high class who still work but do a pretty nice living. Guy’s living the dream.

I mean, this guy lives in an apartment. It’s a nice living I suppose. there are many people with houses there so I suppose he’s technically one of the ‘poor’ from there but he sure seems to be making shit-loads of money. good for him!

anyways, i think I’m making this too much about him. and this is about me. i felt satisfied because, well… maybe because I drove or maybe because I did homework.

Or maybe cause I talked to a good friend whom I’ve known for not so much time but still provides great influence over intellectual curiosity and over my mind.

That’s it. what, is this an essay? am i supposed to end formally if i am to be a professional writer ? hmmm, that’ll be a question for another day to answer…. or maybe you could answer it and tell me how i should live my life.

Hello Stranger. I am me. And i’m blogging.

I feel kinda bad, ok ?

Should I ? I don’t know. I enjoyed all this. The human mind works in very mysterious ways… insert another lame cliché here

I don’t even know how to feel. i don’t know what to think. The only thing that I know for certain is that I’ve balanced my wrong-doings.

Last Tuesday I lied. I gave into a lie. But I’m an honest person, yet I had the choice to not choose to lie. But I fucking did!! And I’m not saying it’s the other person’s fault for suggesting to lie but in fact, it was my fault. Cause it’s my life, my part in the lie!, am I right ?

Well yeah, of course I’m right and if I’m not say it to me by whichever means you consider, ok ?

Now, today I think I’ve redeemed myself by not lying and by doing the exact opposite of what happened if I lied.

And I feel good about it.

At least I know that, so let’s not forget that, alright ?

I like falling in love. It was a nice experience. I would do it again, many many times.

Une critique en rapport à la chanson de Prioritise-Moi

Posted on:	09/27/22 10:06:08
Last edited:	04/19/23 13:50:29

J'ai vu et ecouté a ce chanson originale par Pomplamoose [0]. Vue les lyrics ici.

Ok, donc qu'est-ce que je pourrait dire ?

Bon, je sais pas. Je pense que ça c'est une chanson pas dépriment nécessairement mais réaliste de la realité où on vivre. Elle pourrait être la femme ou l'homme mais à fin on a toujours une personne qui veut d'attention et une personne qui est occupé déjà avec de travail ou quelques autres choses.

La personne qui chante a beaucoup d'intérêt d'être avec la personne mais l'autre personne n'a pas l'intérêt. Il est pas interessé plus de être avec la personne. Il est consummé par plus des choses comme le travail.

Mais la personne - l'homme qui travaile - est dans la date, non ? Il est physiquement avec cette femme mais pour quoi est-ce qu'il ne prenne pas d'intérêt s'il est là dejà.

Je sais pas. Et aussi, analyser une chanson dans ma troisième langue est très difficile, peut-être je pourrait faire une analysis très loin et plus developpé dans la langue espagnole ou l'anglais.

Mais le point est que j'aime la chanson et je pense que tu pourrait l'écouter pour voir s'elle t'a interessé.

This is the page where I publish my salary transparency data. Hopefully I’ll remember to update this in the future.

The idea came from xeisao.net [0]

Internship, junior dev.(part-time,20hrs a week)	2022-06-01	2022-08-16	77 or 2.5 months	$ 4000 MXN per month	I quit because I became unsatisfied with the work I made.

currency

• MXN: Mexican Peso
• USD: United States Dollar
• MXN to USD
  • $ 1 USD -> $ 19.97 MXN (circa 2022)

Love and happiness

See also: Song Love and happiness [0] by Al green

Love and happiness are weird concepts.

whatis love ? and why does our society take such pride and emotion into having it ? I mean, not just society, but my family and me as a whole, right ? Why don’t I get the love I deserve ? Maybe I do, but I just don’t see it.

I’ve tried having love, sharing intimacy with others. But I guess I’m just not good enough, or just not good enough for them. Or i haven’t found the right person at all.

But the point of this blog post is to say that maybe, mayybeee I have the one. Maybe I do. I’ve crossed eyes with her. A lot.. maybe way too much. She’s crossed eyes with me. We’ve crossed eyes. Who started it ? Did I ? Hmmm, maybe maybe not ? You see, on a purely survivalist standard being with that person would most likely yield me success, even if I don’t lvoe her, because it’s come to my knowledge that she is, in fact, the daughter of people who work in the softwaredev/cybersec sector. So does that mean potential success ! Well, of course it does. But also, I’d like to get to know her better.

Because why not, right? Honestly, she seems attractive from afar. Afar, say 6, 8, maybe 10 feet. In the same room, with the voice. With the authority of her voice.

I wonder if she’s read my blog. I don’t know if she has. I didn’t advertise when presenting myself. But maybe she found it through instagram, since my profile is public and there’s a link to my blog and stuff. But she could have also found out thru other means, such as other people, friends, or even the school platform we use. I edited my profile and people can click on my profile and they can see a link for my blog. Maybe she did click on it and was interested in what I wrote. If so, please tell me.

Anyways, what is the point ? These past two days have been rather unorthodox. I think I’ve been preparing my mind for deep, extremeley overwhelming tragedy.

you see, I don’t think that it’s nice, ya know ? to live with a human whose mind is fucking goingn nuts. Knowing that the voice you once heard is lost. The fights you maybe had, the shit you shared, the shit you didn’t. All those feeling, and those actions are kinda lost. But still there and omsetimes, every once in a while come back from that brain and expose themselves. And you feel this ecstacy crawling through your neck and making your muscles contract and be an do so many things but then you..

snap back to reality oh there goes gravity. And you realize the person you’re living with has dementia and just knows that you’re married. At least that’s the perspective I get with the alzheimer’s and dementia my grandma’s having. And of course, there’s my dad. Who is also trying to cope with this new fucked-up reality by making his family try to help her. Which I do not think is bad, but after all, we are indeed making her ( my grandma) a puppet, wouldn’t ya agree ?!

i’m tired. I barely slept anything today. I couldn’t sleep.

And I have kinda a shit-ton of homework and I kinda need to get it done in like less than 50 minutes.

Bye, let’s push this to git.

Oh my, oh my,
with no path for myself,
I got nowhere but the void to go to,
overinformed by everyone,
just wanting to go to the snow,

Oh my, Oh my,
what a free world we live in,
is society doomed?
or am I?

Should i live by critique?
Or by desire?
am I good enough for you?
Is this right?
this wrong?
like this?
like that?
I’m a lazy human for not doing my part!

is there an end?
am I dying?
feels more awkward everyday…
rarely entertaining…

oh my oh my,
I love my nationality,
but rarely do I feel identified,
am I American?
Mexican?
rarely do I with humans near me,
I don’t even know any anthem by heart!
I should work harder, but not that much!
or I’ll become a workaholic!
and maybe will be called a psycho!

should I stop contemplating?
and just do stuff?
maybe… maybe not.

At last my error.

Instead of working I have found myself dealing with some mysery and happiness. Lots of both sometimes. I miss things. I think I miss writing. I like writing at the two a.m. in the morning because why not.

Anyways, I recently bought myself something that actually uses the usb-c port on my computer. The USB-C connection actually has a Thunderbolt 3 controller and yes, in theory, I could just connect literally everything I’d possibly ever need through that cable.

I went to a Best Buy in Michigan to get a thunderbolt 3 capable dock but to my surprise I did not find any of my liking. The thing that was missing the most was a Display Port. Literally none of them had it. Not even the extra expensive ones. I mean, they were all kinda equally expensive, even though they’re probably as shitty as one would expect from too new technologies and not enough real manufacturing of them.

In the past month I stumbled upon a hacker news post talking about thunderbolt 3 was. The conclusion was that the expensive and ali-express bought docks were just as equally likely to fail, not work at all, and or work at advertised speeds.

Anyways, I did find some interesting stuff at the best buy. I found a micro-SD card reader that has both a USB type A (that’s the regular USB port you’re used to) and a USB type C port. That’s nice, maybe I’ll gift it to my sister who both owns a regular laptop without USB type C and an iPad with a USB type C connector, hopefully this will work if she has to transfer files faster.

So I did buy that, I bought it open box [0]! I know, I’m a cheap, ain’t I ? Also, I bought a 100-watt USB-C power adaptor for my computer, to charge it much, much faster. As a bonus, it has a 20-watt [1] type-c port and a usb type-a with a little more amperage than your regular phone brick.

Anyways, I bought these two products. The power adaptor worked great. I can now fast-charge off a single AC connection three devices at the same time! Pretty neat. We’ll see how hot she gets.

The micro-SD card reader did not work. Well, the USB type-A connector did work. So that’s good. I could access the file system off my only not-lost micro-SD card and can play the files just as well as I would on my computer’s port. But the type-C connection wouldn’t work. One of my first ideas was to try on a proprietary operating system that normies call Windows. (un?)Fortunately, same results. Only type-A would work. Although something interesting was that power would indeed work. I could charge my phone off the port easily. But I could not read any data off any devices.

So I thought maybe BIOS drivers but wtf am ieven saying idk. Idk enough to know if the BIOS is in charge of this or not. Maybe Lenovo weird firmware updates ?! I checked but nothing. Just annoying windows 10 fat updates. Some Linux stackoverflow questions pointed in weird directions.

the culprit

the culprit is that… well… not-so-long ago I delved into my BIOS settings and chose to disable the THunderbolt 3 port. To my surprise, power was not cut-off the port and still worked like a charger and I therefore expected it to still be working. But in fact I just jumped into my BIOS a few minutes ago and lo and behold there it was the Thunderbolt 3 disable setting! turned it right back up, worked like a charm. Even if the connection was not over thunderbolt 3, it encapsulates the type-C data port as well, so that’s that. Now I can access my micro-sd through an adapter connected to a USB-C port that is accessed by a mostly open-source operating system.

nice.

• [0] “open box”. - I’ve never heard of this term until a friend of mine who lives in the United States told me. It means that a human presumably opened a product but did not use it. Then this human returned the product and it is advertised on the price tags with a discount and a label that says “open box”. I bought this thingy for like 15 bucks (no tax), like 10 off. Has worked well enough so far.

Well, who am I?

Well, that’s a great question. I don’t really know myself.

If you know french, here is a reflexion essay I made in highschool for my philosophy course: https://files.thetrevor.tech/trevor/misc/qui-suis-je-philos.pdf

I wanted to start off by explaining the whoami Linux (gnu coreutils) command first. But I’m sure it’s self explanatory. Computer systems have users. The command just prints who is the user running the command.

But well… who am I ? That’s one of philosophy’s most-searched questions.

$ whatis umask anyways

So, linux and other operating systems use files. You might have heard the expression “On Linux, everything is a file.”

And Linux uses lots of files. And if everyone had the same rights to all files, it’d be a mess. Unprivileged users would be able to edit critical system files.

small detour:

So, in conclusion folks, applying personifying traits and giving ‘rights’ to computer programs to do whatever they want will create trouble! I’m talking to you, Github! No reason at all to change from master to main. Completely absurd.

detour ends here

So the ext4 filesystem has permission on files. I can get the permission of a file using the ls command with some fancy options:

# -l stands for long options
$ ls -l articles/whatis-umask.md
-rw-r--r-- 1 john cena 780 May  2 21:03 articles/whatis-umask.md

where john is the owner of the file and cena is the group owner of the file. and the first characters are what matter: -rw-r--r-- that garbougle of characters is weird! let’s put some spaces!

-rw- r-- r--. Okay, looks better. These permissions are for the user, group, and other, respectively. Yes, john and cena come into play. john will have -rw-, cena will have r--, and other will have r--. rw means read, write. r-- means read. rwx means read, write, execute. Yes, execute as in execute programs.

But cool thing is if it’s a directory the x means you can create files within the directory ! Try it out in a temp folder ! try making a new dir, looking at file permissions of a folder with ls -lad folder/ and chmod -xing it. can you create files ? folders ? what happens if you revert the -x ?

what umask actually is

the umask command returns the inverse file mask used to create new files within the current shell. Yes, INVERSE. not the ‘real’ mask you get with the ls command.

EVEN more confusingly, you can run the umask -S command to get a set of friendly-looking permissions like in the ls command which will now return the real file mask, not the inverse. You can set the real permissions for your current shell in the same way by just typing out the permissions you want.

e.g.

umask -S u=rwx,g=rx,o=rx

A not-so-long plane ride.

but one without headphones

Technically, I did get earphones. But I just got a kinda severe ear infection from which I am just recovering and it has been a wild ride.

One of my ears used to be plugged but I didn’t do much about it until it started to hurt. I went to a party and then left early because one of my ears was practically burning, or at least that’s what it felt like. Next day I went to the doctor and he told me that I had an ear infection. But this doctor showed me what was inside my ear. And in the other one too. The difference was clear. The ear conduct in the bad ear was very small and red, there were little pimples inside it which were just inflammation. It certainly hurt. Plus, the timbre was barely visible.

And he gave me a shit-load of meds, and now I have to apply some eardrops every 8 hours plus other pills and such. And now it doesn’t hurt, so that’s good! And I’m flying right now and wrote this as the plane was landing, which is a completely unnecessary comment yet one I chose to make.

Anyways, the subtitle of this blog post is one without headphones. I chose not to bring my in-ear headphones because they are very uncomfortable and they might have been the cause to the infection in the first place. So I chose not to bring them at all. But in the plane I was offered some. At first I thought of just saying no, but two people around me said yes so I kinda had to go with it, you know, society ! But I just opened them, barely saw them, then put them in those bags in airplanes and I never used them at all during the plane ride.

I tried to not use digital devices during the flight. I didn’t watch any movies because I didn’t have any over-ear headphones. Plus, I wanted to relax. I tried not to use my phone. Only at the end did I use it. I tried reading a book I had around, I started it a few days ago. It was published in 1980 and I found it at a small independent bookstore, for $10 Mexican pesos. That is, 50 cents of the American dollar. Yes, indeed!

Well, now to the book itself. It is called “Petróleo
El recurso más allá de la capacidad de negociación.” If you don’t know Spanish it means “Petroleum (or oil). More than just a bargaining tool”.

And well, the book talks about oil, gas. Petroleum. It is pretty sincere in the fact that it’s absorbed every conceivable physical thing around us. And he’s right. Still very true in 2022.

But guess what ? I tried to read several pages but I was falling asleep. I barely read one page and after that just fiddled with my thoughts, trying to ignore the crying and screaming from young children in front of me.

I eventually fell asleep. I got woken up to have some breakfast from the airline, since it was an almost four-hour flight. But I refused to have any breakfast, as I had already eaten before boarding the plane. Then I got offered some beverages, I kindly accepted an orange juice. It was nice, I could have ordered maybe a cup of water but I did not. I was tired. Eventually I woke up from my sleep. The person to my left was watching a random movie and the person to my right was also watching a movie. But I did not want to watch any movies or use my phone. Instead, I read and I read. The book is nice. I haven’t finished it, just read a few pages but the writing of the book interests me a lot. He uses grammatical expressions that one just does not find in a post-2000 book. It uses expressions which - at first - appear as nonsense but eventually make a tiny bit of sense.

The book is written in Spanish and maybe some of them will not translate well into English but I’ll eventually put them up here.

I think that’s enough blogging for today, or is it ?

Changing your device's MAC address is risky.

Posted on:	05/22/22 09:02:54
Last edited:	05/22/22 09:04:55

At least that was certainly my experience with it.

I recently installed macchanger [0], a utility to… yes! change your mac address.

A MAC address stands for Media Access Control address. It is a unique identifier address used for network interface controllers (NICs, according to Wikipedia). So your LAN controller and your WiFi controllers have MAC addresses.

But companies and governments have standardized the way in which unique MAC addresses are set. I could, in theory, get into an insecure network and know how many devices are from X or why company. The FCC or some other organization assigns ‘blocks’ that companies can use in order to set these MAC addresses. I think MAC addresses are used in network routers (e.g. the one your ISP gives you) to keep track of who has this or that IP address.

So as I sad in the beginning of this post, I tried changing my MAC address. Because as of now, I could connect to my network and possibly know that this or that device is or this or that brand. Which, in my opinion, is creepy as fuck. So why not be more privacy minded ? So yeah, I tried changing my MAC address to a random one.

So you run the command. Nothing happens, it says that you should try using the --help flag, so I do. There is a random flag, just what I need. I do it. It tells me that I’m missing something. I read the manpage. You have to specify the network adapter. So I run ip a. my computer is connected through an ethernet cable. I get the adapter name. I put it at the end of my command. Now I get permission denied. Fair enough, just use sudo !!. and it works! Now I have another MAC address. But guess what ?

I go to sleep, I wake up the next day. I do not open my computer, do not check on it. The blog is fucked. I cannot sync anything. The server is inaccessible. Why ? Great question.

Then I try all kinds of stuff. I get to my house, I can access it from my Local Area Network. the IP address works. My public ports are fine. Then I remember, I changed the MAC address. Maybe I should restart my web server. That does not work. Neither does restarting the Network Manager.

I give up, I reset the MAC address to its default configuration. Maybe I cannot change the MAC address and not reboot.

So now it works with the default MAC address.

scripting

what kinds of string interpolation does POSIX sh support ?

By Gilles ‘SO-stop being evil’: source and license: [0]

--BEGIN--TEXT

"${blah}" and "$blah" are portable shell syntax: they work on all POSIX-compliant shells as well as in traditional Bourne shells. POSIX also requires other features of variable expansion:

• String manipulation with ${VAR#PREFIX}, ${VAR##PREFIX}, ${VAR%SUFFIX} and ${VAR%%SUFFIX}.
• Conditional treatment of unset variables with ${VAR-DEFAULT}, ${VAR=DEFAULT}, ${VAR+FALLBACK} and ${VAR?MESSAGE} as well as the unset-or-empty variants with :-, :=, :+ and :?.
• Variable length with ${#VAR}.

In all cases, remember that the result of $… undergoes whitespace-splitting (more precisely, splitting at $IFS characters) and wildcard expansion (globbing) unless it’s in double quotes (or a few other contexts that don’t allow multiple words).

You can look up what exists in POSIX by reading the specification. Modern versions of POSIX are identical to the Open Group Base Specifications (without optional components). Older versions are a subset of Single Unix v2.

Unix-like systems without a POSIX shell are extremely rare nowadays. /bin/sh is a non-POSIX Bourne shell on a few systems, notably Solaris, but a POSIX shell is available (/usr/xpg4/bin/sh on Solaris, and you should have /usr/xpg4/bin ahead of /usr/bin in your PATH). If you need compatibility with Bourne shells, check the man page on the systems you’re interested in, as there have been many versions of sh with slightly different sets of features. Sven Mascheck maintains a page with a lot of information.

Okay, fine. The DLL injection on the windows 10 uninstaller is a fair vulnerability.

But what the hell happened to ‘I own my machine’. I can take pride in fucking up and accepting my own decisions !?!?

where’s the unix philosophy at ?

since when do I have to own a git repo to look at it? Wasn’t this the decentralized control versioning system created by Linus Torvalds? The one that he kinda made in about 2 weeks but has been the top CVS for what ?, more than 12 years now ?

I mean, this is an absurd decision. Hundreds of CI/CD (Continuous integration / Continuous delivery ).

Even my fucking simple AF git hooks died. Since I am running as another more-unprivileged user now I don’t have the right to clone a repo who’s owned by another user in the system ? Seriously, what the hell is wrong with that !?

This is, in my opinion, certainly a stupid decision.

Oh my God ! It’s my last day of school ! Well, I still have another day tomorrow but we’re practically doing nothing! I still have like 3 final exams that I’ll be doing this Friday or the next week.

But whateveeeer ! Today I’ve given myself the day. I had a ‘fiesta de cereal’ (yes, a cereal party) ! Everyone just brought a ton of sugary cereals, milk, almond milk, other kinds of liquids that are called milk but I don’t think are actually milk, toppings, spoons, bowls, and glasses for drinking and apparently serving the cereal !?

But it didn’t really feel that good. I feel kinda bad because I was supposed to bring cereal and other stuff but I did not.

But now I feel bored. Yet with self-guilt, because I am not doing what I am supposed to. I have some not-yet-done calculus assignments that are not difficult, yet too easy. And that doesn’t motivate me to keep on going. I’ve probably already passed the subject, and now I just need to take the final exam and if I want finish those calculus exercises. Which will most likely serve as practice, which does help.

But why am I here? Just to suffer ? Who knooowwws mate! Also, I watched a tv show for the first time in a while. And with another human being. With a friend, actually. I watched the 2nd episode of Mr. Robot (2016). I’ve already finished the show, yes, the whole four seasons. It really brings out very dark yet astonishing thoughts within your mind. I don’t want to talk about it because I could spoil it. If you want to watch it it’s available on amazon prime. But hey, if you don’t want to give your money to one of the biggest e-commerce shopping conglomerates around the world just send me an e-mail and maybe I’ll let you copy off the downloaded episodes I have. (Don’t worry, I still pay for amazon prime and I did watch it there first so -some - money will definitely be going to the actors/director, etc…)

And the scenes. The writing style of the show. Very beautiful. Or maybe I’m just so fucking biased and I praise this show like no other because I haven’t watched that many dramas. Well, I’ve also watched House M.D. Yep, the whole eight seasons, baby! It gets boring after a while. But point is, Mr. Robot is. And if you want you may watch it, but I must say it does include sensitive and/or disturbing content.

But that’s what a good show is, right ? One that actually questions your being, existence and merely mixes you in with the feelings and does not merely end and your mind says: “Oh well we’re done here.” No, your mind Will want more!.

I think that’s enough blogging for today, plus dependencies.

So no, I’m not done bloggging yet.

dependencies

Dependencies are weird. This is some kind of buzz-word. A real one, actually. It stands for what it means. At least in software. A software, a program, or a set of programs, may depend upon other programs to function. Libraries, let’s say. Frameworks, etc…

And there’s this thing called dependency hell, from the internet discussions I’ve read it’s mostly within the front-end web developing space. But it could also happen in the backend. Certain software requires certain, very specific, cryptic - even -, versions of the software and sometimes software collides with other software. Libraries are just collections of minified code (sometimes not even minified) or maybe even compiled and using a shared library. But there’s just a gigantic web of tech stacks that we utilize on a daily basis. That is why I strive for minimalism within my life.

Although sometimes extreme minimalism may lead to extreme dependencies, which I am trying to - most definitely - get away from. Are friends dependencies ? definitely !! They most of the time are. We sometimes need them. Friends are there when needed, right ? But sometimes they’re always needed. Of course, that is bad, that’s dependency hell.

Sometimes your thoughts wander way too much and you don’t have time to talk that much to people yet you’d love to talk more and more and more yet time is of the essence. And so is my life and so is theirs.

But generating dependencies is sometimes bad. when some of the code is very simple to make, but tedious, you may go to using libraries. But if a develper rants about not being paid enough money and shutting down all his very minimalist packages and shutting down very popular web services that says that something’s very wrong in the developer space. Not only for the fact that this guy’s not being paid enough ( which is meh ), but also because the developers who were using his code did not plan ahead.

But hey, take my comments with a fucking grain of salt cause I’m still in high school if that counts. But maybe I’ll get a headstart, I’m trying to get an internship.

Getting access to public wifi internet on Linux

Posted on:	05/02/22 20:53:00
Last edited:	05/02/22 20:53:00

Okay, so you’re at a mall or something, there’s public WiFi. Cool. And you can access the internet with your phone. But you open your Linux computer and connect to the network, yet nothing happens ! I’ll show you how to fix this.

Most public wifi networks use what is known as a Captive Portal. It is merely a login page used to authenticate control over Wi-Fi hotspots (Nyman, 2013).

tdlr

just go to http://192.168.1.1 on a web browser. It should redirect you to the login page.

tldr 2

tldr didn’t work ? Open a web browser, create an incognito window, go to a website you’ve never visited before. It should redirect you to the login page.

tldr 3

get into a terminal. type the following command: ip route. you should get something like:

$ ip route
default via 192.168.1.1 dev zwn0 proto dhcp metric 600
172.17.0.0/16 dev docker0 proto kernel scope link src 172.17.0.1 linkdown
192.168.1.0/24 dev wlan0 proto kernel scope link src 192.168.1.68 metric 600

get the first IP address under default. In this case, 192.168.1.1. That should redirect you to the login page. If none of these solutions work, you should try reading this [0] stackoverflow question. It has great explanations on what could be going on, as well as multiple solutions.

wut

if you’re on a nice Desktop Environment (DE), the captive portal page will most likely open for you just as you connect to the network.

make Cheese Garlic Bread

Posted on:	05/01/22 14:15:28
Last edited:	05/01/22 14:15:28

Note: This is a verbatim copy off the recipe found in the description off this video.

Cheese Garlic Bread

*** Please note that I have written down the expected questions as TIP.

You make your own fluffy bread, and the bread you eat when it’s warm is really delicious. The combination of the subtle garlic scent and the ever-stretching mochi cheese is the best. It’s not difficult to knead so let’s make it together~

*** Weighing is scale (g), rice spoon (tbsp), teaspoon (tsp) weighing.

[Diameter 22cm] ✤ Ingredients for dough -200g Bread flour -1 Egg (can be omitted/replaced with milk) -20g Sugar (2tbsp) -4g Instant yeast (1tsp) -3g Salt (1tsp flat) -80ml Warm milk -30g Unsalted butter at room temperature

✤ Garlic sauce -1tsp Minced garlic -1tsp mayonnaise -1tsp sugar -0.5tbsp Chopped green onions -1tbsp Egg (can be omitted) -13g Unsalted butter at room temperature

✤ Topping -140g Mozzarella cheese

✤ TIP -Use bread flour as much as possible. plain flour has a less fluffy texture. -Fermentation can be done by soaking in warm water. -The airfryer temperature is similar to that of the oven. Adjust the temperature while looking at the color.

Yes, the Mark Zuckerberg!

More like… only one, unfortunately.

I’ll make some commentary at the end.

I got it from [0]

Here’s the text:

—-BEGIN TEXT—-

10.28.03

8:13pm. I need to think of something to occupy my mind. Easy enough now I just need an idea…

9:48pm. I’m a little intoxicated, not gonna lie. So what if it’s not even 10pm and it’s a Tuesday night? What? The Kirkland facebook is open on my computer desktop and some of these people have pretty horrendous facebook pics. I almost want to put some of these faces next to pictures of farm animals and have people vote on which is more attractive. It’s not such a great idea and probably not even funny, but Billy comes up with the idea of comparing two people from the facebook, and only sometimes putting a farm animal in there. Good call Mr. Olson! I think he’s onto something.

11:09pm. Yea, it’s on. I’m not exactly sure how the farm animals are going to fit into this whole thing (you can’t really ever be sure with farm animals…), but I like the idea of comparing two people together. It gives the whole thing a very Turing feel, since people’s ratings of the pictures will be more implicit than, say, choosing a number to represent each person’s hotness like they do on hotornot.com. The other thing we’re going to need is a lot of pictures. Unfortunately, Harvard doesn’t keep a public centralized facebook so I’m going to have to get all the images from the individual houses that people arein. And that means no freshman pictures…drats.

12:58pm. Let the hacking begin. First on the list is Kirkland. They keep everything open and allow indexes in their Apache configuration, so a little wget magic is all that’s necessary to download the entire Kirkland facebook. Child’s play.

1:03am. Next on the list is Eliot. They’re also open, but with no indexes in Apache. I can run an empty search and it returns all of the images in the database in single page. Then I can save the page and Mozilla will save all the images for me. Excellent. Moving right along…

1:06am. Lowell has some security. They require a username/password combo to access the facebook. I’m going to go ahead and say that they don’thave access to the main fas user database, so they have no way of knowing what people’s passwords are, and the house isn’t exactly going to ask students for their fas passwords, so it’s got to be something else. Maybe there’s a single username/password combo that all of Lowell knows. That seems a little hard to manage since it would be impossible for the webmaster to tell Lowell residents how to figure out the username and password without giving them away completely. And you do want people to know what kind of authentication is necessary, so it’s probably not that either. So what does each student have that can be used for authentication that the house webmaster has access to? Student ids anyone? Suspicions affirmed –time to get myself a matching name and student id combo for Lowell and I’m in. But there are more problems. The pictures are separated into a bunch of different pages, and I’m way too lazy to go through all of them and save each one. Writing a perl script to take care of that seems like the right answer. Indeed.

1:31am. Adams has no security, but limits the number of results to 20 a page. All I need to do is break out the same script I just used on Lowell and we’re set.

1:42am. Quincy has no online facebook. What a sham. Nothing I can do about that.

1:43am. Dunster is intense. Not only is there no public directory, but there’s no directory at all. You have to do searches, and if your search returns more than 20 matches, nothing gets returned. And once you do get results, they don’t link directly to the images; they link to a php that redirects or something. Weird. This may bedifficult. I’ll come back later.

1:52am. Leverett is a little better. They still make you search, but you can do an empty search and get links to pages with every student’s picture. It’s slightly obnoxious that they only let you view one picture at a time, and there’s no way I’m going to go to 500 pages to download pics one at a time, so it’s definitely necessary to break out emacs and modify that perl script. This time it’s going to look at the directory and figure out what pages it needs to go to by finding links with regexes. Then it’ll just go to all of the pages it found links to and jack the images from them. It’s taking a few tries to compile the script…another Beck’s is in order.

2:08am. Mather is basically the same as Leverett, except they break their directory down into classes. There aren’t any freshmen in their facebook…how weak.

—-END TEXT—-

commentary

Wow, nice story. I was definitely able to follow through with what he was saying. Although I must say, I don’t know how to code in perl. But I do know what PHP is! So that’s good ? Hmmm, a lot of the tech hasn’t changed.

Would definitely be fun to make this as a challenge. Making a faceSmash for my school !?

Dope! But a lot feminists would probably curse at me for an entire week straight and I could get expelled.

I’d probably just need to steal some credentials off one professor who has enough admin privileges.

Hmmm, maybe I’ll go back to this. Hey friends! Don’t kill me, if you don’t want me to do this then call me or something.

I drank coffee

Maybe this is placebo but point is I kind of am a distracted person and feel like my heart is pounding relatively fast.

Yet today I decided to drink at seven in the p.m. one and a half cups of american medium-roasted coffee from Garat. and i ate it with some cookies. maybe too many cookies. Then I started using my phone like a crazy person and started sending a shit-ton of links to a friend. Maybe I went overboard with the links.

And the coffee kinda made me happy. I’ve never felt this alive before.

Like ideas just flow into my head and I execute them. Or maybe I’m just being very reactive to my vices. Since, yes, being on instagram for like five hours straight is not healthy. Also, I got on a call with another friend and helped him out on a school project which I hadn’t even started at the time, then got him to let me join his team. The code was almost kind of done, and he made most of it. I feel bad for that. Kinda.

I don’t know. But maybe without me he wouldn’t have gotten the last coding part. We barely saw any programming principles in class.

Also, is it ok to have for dinner only oatmeal with some granola ? And then take antidepressants and an antibiotic ? I hope I don’t fuck up my stomach.

My keyboard definitely makes a ton of noises when typing.

The feeling of Uselessness

i feel useless

yes, indeed I do. Even though I can provide ideas, experiencie and opinions within my area of expertise, I do not fill fulfilled.

I feel not useful. I am trying to teach someone something but they really don’t get it! They barely get it at all! You are a good person, kinda trying to understand but you’re not at all putting in the effort. I explain, you look at me in deception and I try to explain but you barely make any questions.

I had already teached you some of this which means that you are either a) very distracted and not interested in learning about this topic; b) you don’t like me, you’re thinking of something bad or arrogant I made; or c) your incentives to learn are non-existant.

That is bad. Any of these problems is bad. Some worse than others. Communication is key. Yet you don’t say shit.

You don’t seem to want to learn. I think I’m trying my best in order to teach but neither am I inspired at all. I don’t like working for tyrants.

---

And you know, after being absent on a team and being occupied at other things - for several hours - I can tell you that my opinions are not valuable to the team. I try to give ideas, let others be yet the design we were working on went to fucking trash and we started doing everything from the start.

And I truly try to help but none of the actions I critique are valuated. I can say good job or whateved but at this point I’m practically nonexistent.

A very relatable song. Just listen to the crisp lyrics:

Waste my Time - Crystal Casino Band (youtube)

Oddly enough, this song appeared as an advert in an instagram story. I was just bored at a party after a while and I started using my phone and then lo and behold some radio frequencies that we humans interpret as sound and my brain - me - has appreciated it.

I’ve just never found such a relatable song as of now. Is this happiness ? Does it transfer sadness? Not sure, yet.

Listing Installed Fonts on *NIX systems

Posted on:	04/22/22 21:29:15
Last edited:	05/11/22 21:20:09

weird, right !?

There’s the fc-list command. This binary is installed with the fontconfig package on Arch Linux.

But if you don’t want to install 1.1 MB of not-so-useful stuff, you can list your installed fonts by going to this directory:

/usr/share/fonts

then you can run something like tree. There will be several folders and a ton of .ttf files. my dir listing looks like this:

> ls /usr/share/fonts
adobe-source-code-pro  gnu-free           liberation  old            ttf-linux-libertine
cantarell              gsfonts            misc        TTF            xscreensaver
encodings              kanjistrokeorders  noto        ttf-jetbrains

you can now get all your installed fonts on your Linux system!

Le Revue dans ma classe de français

Last edited:	04/21/22 21:59:40

Donc aujourd'hui ma professeur de français a voulé de faire un revue de toute les conjugaison en français.

passé composé

Donc on a commencé par le passé composé: très simple. C'est seulement la formule:

passé composé = auxiliare + participe passé

où l'auxiliaire est être ou faire. Le verbes qui doivent être conjugés avec être sont tous les verbes pronominaux et les verbes de ‘mouvement’ ( avec la maison etc…)

imparfait

c'est pour décrire des habitudes

et je suis un peux ennuyé d'écrire.

Mais, merde!

I will - at least for now - not tell you the specifications, but what can be seen closest from the eye.

First, a quote from Mahatma Gandhi, whom I barely know. I only know that he has been one of the most important human rights activists around the world, or at least that has been portrayed by the Western Media. I know he is from India and was part of several peaceful protests to liberate the country from Britain.

The quote is short, yet simple.

Whatever you do will be insignificant, but it is very
important that you do it.

In other words, even when you think that whatever you are doing might not have an effect on society or others, it might actually have it; even if it’s not so obvious. Maybe successful people, startup leaders, millionaires will say that this is merely obvious. Maybe because successful or ‘popular’ people within the success bubble are used to growing a real kind-of-an-ass conscience. Success can be seen in many ways. But I think that people ultimately want power. Power leads to control. Some of these may be achieved with money. But others just with commitment. Commitment to follow your gut, not just fucking numbers. Who cares if people say that nobody will want electric scooters or that selling books through weird screens that connect through the telephone and make weird noises will revolutionize the industry. Success stories from tech are just so inspiring to me for some reason. They certainly committed to some of their dreams and actually did them. Even if they were at the brink of losing it all. Just like when Elon Musk invested almost all of his money in Tesla and attempted to create an actually good electric vehicle. and he made a nice sports car. Respect. But now his company kinda sucks, he uses proprietary software and doesn’t let people hack their car. Just bans people from their super-charger network. Limits right-to-repair on the car. But Tesla’s mission was never to be a good company. It was to revolutionize the car industry.

Tesla’s mission is to accelerate the world’s transition to sustainable energy.

Well, yeah. technically tesla was not founded by Elon Musk. More like he was the fucking angel investor who took his chances and bought like 90% of the stock even when the company was almost doomed to fail.

So yeah, tesla's mission is not to be a good company, or create a good product. Maybe they are kind of attempting to do this, or they were at some point in time. They merely wanted to spark competition. This has made very big companies to heavily invest in real electric vehicle technology. Including some that Tesla may not even have. But are electric vehicles really a good thing ? Not sure.

Maybe I’ll talk about that in another article. Let’s move on to the next quote from my terminal.

---

Wu wei

I actually forgot what this meant. Somewhere on the internet I stumbled upon chinese philosophy. After a quick duckduckgo search I found out that Conficius was kind of the guy who coined the term. It comes from taoism, a philosophy of life - sometimes referred to as a religion [0]. In Chinese, wu wei literally means inaction. It refers to actions that are effortlessly executed without even thinking about them, just doing them and aligning to our needs, not our desires.

next phrase.

---

CONTROL your vices

this is a phrase I made up. Control. Meaning, Get a handle of.... your vices. my vices. vices meaning these things, attitudes, actions, thoughts that may take your life and thoughts away from what you have to do.

and then an almost verbatim definition from the merriam webster dictionary of the word vice

vice (Merriam Webster) \ ˈvīs \ Definition of vice (Entry 1 of 4) 1. b: a moral fault or failing 2. : BLEMISH, DEFECT 5. : an abnormal behavior pattern in a domestic animal detrimental to its health or usefulness.

first definition: a moral fault or failing. Moral. Talks about morals. Kinda good and wrong. Fault. Something that may have been wrong, corrupted. Failing. Not working well.

second definition: BLEMISH, DEFECT. simply something that is not supposed to be there.

third definition. an abnormal behavior pattern in a domestic animal detrimental to its health or usefulness. weird but ok. but the most correct one, I’d say. I am domesticated. By my own conscience and rationality. I am indeed an animal. A human animal. Aware of its conscience. And yes, vices are detrimental, detrimental to the health or usefulness to the creatures who are executing them.

---

and last but not least, quote:

carpe diem

Latin for seize the day. I first heard of this on the movie The dead poets society. Very good movie. Sad, but true. Yet really captures reality. it is simply a phrase for living in the moment, not worrying about past or future or maybe not even having a notion of time! But wait. The phrase already mentions ‘day’. A word that can only be interpreted if we have time, right. Well, yeah. I just thought about that. But there’s not much to it. Maybe if you put my face in front of you i’d be a tad bit more inspired to talk to you about the why I chose these phrases to appear every time I open my terminal. But whatever. have a nice day.

end.

references

• [0] : sometimes Taoism is referred to as a religion because it can be something that people believe in. Yet it sometimes is refuted because there isn’t a strong base in what to believe, there is not a God or a church. It is more a school of thought than a group of followers.

A funny short film.

Posted on:	04/21/22 20:37:21
Last edited:	04/21/22 20:50:32

what the film NUMBER 2 here: https://youtu.be/hZFm6bIqeh8

Click here to view my review. With spoilers of course.

The film tests the boundaries at which we will conserve and preserve and save intimacy. And embarassment. I guess Danish women aren’t expected to fart randomly at a supermarket or in front of a male friend, are they ? Pretty embarassing if you ask me. I don’t understand why she didn’t go to the store bathroom; maybe there wasn’t one…

Of course, we shall discuss other things. Like the fact that she didn’t want to tell her friend that she was actually busy and instead held a relatively long conversation with her friend.

I guess boundaries go a long way. Just as she did not have the trust to say I have an emergency she might do that when not feeling safe.

It is impossible to determine how humans will work under a society based on rules and social movements, structures, and just anything at all. Like how do you define what’s acceptable ? is it f'ing ok to say “Hey I have to fucking poop, get out of the way!” ? I would probably say that. Because I’m honest, sincere. I appreciate honesty. I don’t like to bluff. If someone wants me out of people’s private conversations and I’m there. I won’t leave until these people tell me. And if I get the cue that they’re telling me to gtfo, well then I will tell them ok but to just be direct.

I don’t know what else to say. Seems like people put big effort into this film.

It uses several examples of embarassment as away to engage the viewer, or maybe not. Maybe that’s the 5,4,3,2,1... at the beginning. That kinda gives us a feeling of fake nostalgia that never happened. Because who’s actually watched a real movie with those countdown numbers. But now I’m criticizing myself for saying ‘real movie’. what is that, anyways? How do you define a good movie ? A good film ? Was this a short film ? Or just a film ? Would it be bad to name this as a good film, who decides a good length for a film. Why should the amount of effort matter or the amount of time or anything at all.

Humans have reason. Or a conscience, as we say. We are incapable of imagining thoughts without being aware of the thoughts themselves. Very weird indeed. And yet we live in society; we communicate and have these complex hierarchy instructions that sometimes let us have more power, and therefore more control, and money.

What is it that we ultimately want in life ? Don’t know.

Maybe I went too far on this one. Let me know if this sucks or rocks!

Yes. And there was light, after darkness. And there was darkness after the light; yet no one in the whisper town seemed to know for sure when they were.

Today… was a weird day!?

Yes, believe me mate. Morning, as usual.
I woke up late, I was not due early; my sister had to be on campus until eleven in the morning. So I was going with my mum. *sigh*.

Yep. But I hadn’t showered the day before, nor the day before that. So it was time, I had to do something, make something in order to make myself not feel so bad for not showering enough.

So you know what I did ? No ? Yes ? Well, I showered. And I sure fucking did. Boiling hot water. Soap. Shampoo. Cold. Morning. Not-that-late. Water. Sink. I showered.

I started rinsing my whole body with this prestigious liquid that supposedly keeps me - and humans - alive. Water. Did I like it ? Kinda, I was thirsty. My throat was soar.

Then I applied my face skin care soap. A bar of soap. Create a puddle of soapy oatmealed liquid in your hands. A cave. A round cave. You make foam. You make light. Yet you smash that light on yer face. My face.

You scrub hard enough for some oily stuff to kinda come off your face. You wash. You wash. You scrub with water going all over your face. Kinda hot, innit ? Yes, hot. rinse, rinse; rinse rinse!!!

Now Shampoo. Just soak all your hairs in water. (HAAAAIIIIR!!)

Then apply the liquid shampoo.

---

Me, as I’m writing this:

It is starting to get cold. It is April the 20th.
I was hoping for more sun.
It’s kinda coming out. The Sun.
And there was light.

---

Okay, so shampoo. Boring. Boring little details. No. My hair was numb, it wasn’t numb it was just weird. Greasy, greasy. Barely combed. My hair was tangled in itself. The hot water helps much more than cold water. It helps to untangle the hair. Make it more uniform, real. Maybe even crisp. Shampoo. A fancy load on the palm of my hand. Shampoo. Hard to follow? I’m writing this from my keyboard, words are more difficult to describe than before. Am I imagining things ? Remembering ? Is my writing bad ?

Who knows man! Let’s hope I know !

Anyways, I shower. Ins and outs. Well here, well there. Not so much blue soap. Because I’m too lazy to go get a new one maybe 30 feet away.

Okayyyy, so showwweeeeer.

Why did I shower ? Well, I ws supposed to shower yesterday. Yet I did not. Yesterday I went with my friends to a bowling place. Bowl. As in those weird cones that they make with some cutting rotary tool; they cut wood, well, into bowls. Not the kind of bowls you eat popcorn in. The kind of bowls you make fall with a big, gian, ball made of God-knows-what. but no, I am not religious, as of yet. But I think I should be Yes, TDA, Gaby.

I am ashamed of it. Yes. I have met another human being with TDA. Ecstatic to meet another human being with the same thing. Ecsatic I was not, but the person whom I met. But she told me that she did not have her meds. There was (is) a big medication shortage for psychiatry. Yes, the kind that cures depression and the kind that helps with TDA, trastorno de deficit de atencion. Or Attention deficit disorder. ADD. weird. name. but ok. So I was ashamed because I did not want to take my meds, but I kinda was taking them. But they were not working. I think they are not working now. But you know what? There is a certain limit to what taking a 3-gram pill everday in your system can change in your bodi and bodily fluids. Brain is weird. I have conscience. I am aware of my medications. My dose has increased. It is weird, yet I am kinda still not in the zone. I go and go and merry-go -fucking-round. Feelings are weird. I am not yet disciplined enough to get to French!

Oh, french! Fuck french! No, you love French. Hecto, you love french. you are asleep yet awake writing whatever the fuck comes to mind. You are kinda lucid. You are not lucid. You are alive. same as lucid, you asshole! Lucid is almost the same as alive. But I mean lucid. As in lucid dream. So by lucid you meant lucid dream ? Yeah, man.

You are not in a lucid dream. I think. YOu are not. I f we are, it’s been a little fucking long time to wake up.

What loneliness ? Loneliness, son !? Nah, just your thoughts. Perception.

Frencxh!!! We were in French. I did not arrive early to French. I got finished showering at around seven twenty in the a.m.; I went to the kitchen. I ate. Ate, eaty-eaty y'all. Wait, I’m lying to you. I did not finish showering at seven twenty in the a.m.. I think I was by the kitchen at around seven thirty-three in the a.m. SO no, I was not early. Yes, I was already late to the kitchen, I think. Thoughts are weird (see no thoughts, head empty music playlist).

Anyways, so much information. Going through my head, right now. Conditions apply. Strings definitely attached. Comes with prethreaded brain. And a ton-shit of thread to re-string or just add new strings, new ideas. New recursion and inception of thoughts. You can go as far as you want, as long as you don’t fucking over-boil your head, or overheat it. Don’t overheat my head, mate!

Okay, so I ate egg. Egg. With red tomato. jitomates in Spanish. The ji is for red. you can probably guess what tomates stands for. So I did not like the egg. My Mother was there. It was cold. The egg was cold. Not warm, at all. We were late. Father came. Do not remember what parents talked about after that. Finished eating boring egg; cold boring egg. But I did drink water. Then drank medicine. Well, more like popped my meds like candy! (yes, m.d. house reference).

Okay, so I went away… nOOOOOOOO Fuck fuc k fuck. I just remembered waht my mother and father talked to me about whilst in the kitchen. Weirrrd. I will not tell you. Because I do not want to overheat my brain and go into so many levels of remberance or inception, as I seemed to have baptized this phenomena. Phenomenon. Phenomena ( with an accent, tilde, kinda) aaaaaaaaaaaaa;; dont' start again man!

Okay, anyways. I went away to wash my teeth. Teeth in mouth. Where the fuck else ? Don’t be sad. I washed my teeth. I got my phone, my charger, my knife, my car keys, my suit. I went downstairs. Downstairs, that was the word!

And I started to gather all my shit. I put the charger in the bag. I put the phone in the suit. I put the wallet in the suit. I suited up. Nice pun!

I went for lunch. I gathered everything. I put things in the car. I went away with my mom. Time was probably around 7:43 in the a.m.. in the a.m. nice words. We were late. My Mom kept telling me that I should not be this late! I’m an asshole!!! Yet I was there, arguing with my mom, playing the devil’s advocate sometimes and other times just bashing out my own thoughts, mate!

Okay. So I got maybe like at seven o six in the a.m. To school. I need to pass a stupid covid-filter. I did not. I ran. They only take temperature and ask for your student identification. I opened my wallet, where the identification was visible. All this while I was running. They understood. They empathized. THey thankfully did not stop me. Thank you madam, and sir.

Then I ran to the french classroom. Same as almost any other classroom. Except that classroom’s name is la progracueva. But that ain’t important. What’s important is that I was late. I thought the teacher was not going to let me through. Yet I sat down. She was mad. I was the only one late. Fuck. Why is it that every time I arrive actually early to my french classroom my teacher starts taking attendance late ??? Whyyy ??

Today she took attendance early…. SO yeah, fuck. But I did the assignments. I finished the teamwork, I was the admin. For once. Not for once you sucker, like many other times like 95% of the times in the french classroom. Where my class mates say literally shit and don’t know how to speak a dime of french and I have to fuck up my french on purpose so that they don’t look bad and don’t get a grade that bad.

Anyways. I went to calculus class. The medicine worked. Gaby and Fer went away. They said they had finished the work. I don’t know if they did. No care. But problem is that I wanted to go with them, but something stopped me. The fact that there was still a handful of people inside the classroom. The fact that maybe I missed having Gaby around and talking to her yet if I had gone outside the classroom I would have been with her but what the actual fuck am I saying !? Not in a like-miss way, just in a friend enjoying deeply intellectual - not actually intellectual but there’s definitely a better word for it - conversations.

But my friend Jenny and Alex would not get up. They were committed to finishing schoolwork. They were not finishing it. No distractions. No nothing, they were both finishing their assignments individually. Alex was, helping - every once in a while - Jenny with confirming mathematical procedures. For integration by parts Pretty weird topic if you ask me. It’s recursive. Meaning you may need to execute the integration by parts in some steps that you’ve gathered from executing the integration by parts. Running the same function for given values until you get more useful values that you can use in order to get even more useful values and maybe even an integral that actually works!

So yeah. These two friends. good friends. best friends I’d say, I also have other best friends, you know ? okay, fine. SO these best friends inspired me by not saying anything but by doing and helping each other out. They did not budge. they did not give away their stance. They stood their ground. They finished their calculus procedure. About halfway of their procedures I started mine. With the first one. Morel ike I started doing it once Jenny had finished all of them. Five integration by parts problems. I started from scratch. Zero. nada. nothing. I executed first order in list. I opened my notebook, wrote it down with a blue pen. No, not with a blue pen but everything in pencil. Not in a pencil per se but in a mechanical pencil. So yeah. Life do be like that. I got the first one kind of wrong. I was calculating an integral when I had to do a derivative. Weird cows and shit. You’ll get it when you get it.

So yeah, Alex Gomez told me about that. then I flied. and i flied and i flied and I got everything right and was checking it with Jenny’s procedure. Good, I guess. Then I got stuck in the 5th question and Alex helped me a tad bit out. Or did he ? I think he did. So, anyways, these two were awaiting for my finish. I took a document scan on my phone, exported it to a portable document format file format. Then uploaded it to the platform where we were supposed to upload the calculus assignment. And I did, I thanked Jenny. I thanked Alex. We went away. then i don’t know what I did. Wait, I don know. I had lunch.

I was kinda mad. I felt bad for the teacher. Actually, before Gaby - my friend - left the calculus class, she helped me out and gave me recommendations on how to be better-disciplined. She helped. I did not practice but she gave me good brain-tricking theory. Thanks, Gaby. Anyways, Delphine, french teacher. woman. with a tiny kid. I had to do something, I though of going to talk to her office.

But I never actually did ? Why ? no idea…

Okay, so now was time to get my lunch. I confused cars and eventually found it. It was open, of course. Because my mom knew I hadn’t grabbed my lunch. Thanks, Mom. So I, of course, grabbed the lunch. My lunch. Partly prepared by my mom. Oh, fuck! My mom brought food from the house for me. Yet I bought food at the cafeteria. What an asshole I am.

Fuckfuckfuckfuc. okay, so back to food. Went for food, went for bottle of water. went for bottle of tequila. No, unfortunately not, I donot drink - yet. So I went to the benches where my friends were at. But I had peeing desires. I wanted to pee. Actually, I want to pee right now, mate. should i stay or should i go ? best thing i got out of stranger things. the glorious name and feel and existence of this song!.

Okay, so I actually did go to pee. See the commit history for this file.

So, as I was saying, I went for lunch. Then I went to pee. Then I ate, was on my phone. accompanied my friends Pau and Fer for some chocoflan but there wasn’t any ! :( . I was definitely expecting chocoflan. But it unfortunately did not happen. I wanted chocoflan. But then encountered Ernesto Caso, a former tecbotian. Well, he still is a tecbotian.

anyways, I waited for my friend Fer who was, in turn, expecting her food from a cafeteria place. She had ordered a croissant. After some minutes Fer did get the croissant and went to the eating benches. Or just benches, mate. And we ate. ate, and ate. Eventually I talked to Pau.

about her boyfriend, weird. Her boyfriend seems nice. I won’t reveal too much personal information but he is from Switzerland. So yeah. She has only seen him once.

Then it was eleven o'clock. and duty was to go and see Juan Pablo, J.P. A very dedicated person. highly disciplined to do anything he wants. I believe in him. But times change. And so did this one. We were expecting him at an auditorium with another group of people to see him defend his portfolio with all the accomplishments during his stay at high school. But we got the times wrong. Maybe I did not hear correctly.

So we went to anothe auditorium, but no one was there. We then went to a third one. No one was in any of the auditoriums. I wrote JP. He did not answer. He eventually did, saying that the time at which he would present would be thirteen-hundred hours. one in the p.m.

So then we had time to kill. But I went to the bathroom. Again. This time to poop. But I took a long time. Almost every time I get to any bathroom I complain in my head and pretend as if I were writing a blog post - like this one - in which I complain about the automatic sensors that don’t work sometimes. You go to poop. When you get up, toilet flushes. That is the objective. In practice, if I move a tad bit - while pooping - it will flush. sometimes. But that day I also complained about the lighting. For this specific toilet. It’s good and all to absorb natural light. But there was and barely is any light available for this toilet. Literally ALL the lighting for the pee-only bathroom and the handicapped toilet are perfectly lit, even with artificial lighting!. But this one toilet is enclosed in a small space and does not have any light over it.

So yeah. I took a long time in the bathroom. Questioning things. Pooping. I don’t remember much from today’s toilet-go.

Then I returned to the eating benches. No one was there. A few minutes came by, Fer arrived. She told me everyone was at the workshop. good, I said. I told her that maybe I’d accompany them. She said ok, then left. Then I left. I was missing water. I wanted water. I wanted sun. I wanted music. My throat was - still - sore.

So I went to Arqui. Plenty of sun. A lake, grass. some benches. some chairs, some rocking chairs. some inclinated chairs. some fancy inclinated chairs. So I went. And enjoyed the sun. And enjoyed the music I was listening too.

I went to fetch water. I went to the restroom. Then my phone started getting hot because the sun was so awesome and I like the sun and it was near overheating and unusable because iOS stops the software if it’s near the sun death.

So I went back. At this point, it was certainly past eleven in the a.m. and it was near noon, a.k.a. twelve in the p.m. Close to my physics class. In terms of time, at least.

So I went to the tecbot workshop, my friends were there. We went to physics class. There, I talked to my friends, discussed on the architecture of our bridge and then went away with The Mickey and the powerful Gaby. I got some glue, stole some pasta from my friends. then we parted away to CITEC. a place where there are computer and fancy big laser color printers. And we logged into a computer. Looked again at designs because why not, while talking about pretty heated topics on anything at all. I kinda met Mickey, I got to know a few things here and there about him. After that, we actually started building structures for our pasta-and-glue-only bridge.

And we talked and talked and talked. Mainly with Gaby. Some time with Mickey. then it was time. remember about thirteen-hundred ? one in the p.m. ? Yes, it was JP’s presentation. We were kinda late. We tried to wrap up as quickly as possible while maintaining the strucure of our pieces and wrapping them in newspaper so that they could dry out in pure calmness. So we ran, towards the Auditorium 1. One.

So now we’re in the auditorium. But J.P. is not the first person to present. He was actually the last. whatever. the other presentations were fine. They did great. It’s public speaking. Today there were more and more and many more friends. The auditorium was presque-full.

And then it was two o'clock. And I was kinda tired. I was tired. I am tired. then I honestly don’t remember much about anything.

eventually, a friend told me that some people were cutting hair and giving it away to people without hair. I had thought about this altruistic act for a long time. Several months, I’d say. But I’d keep making excuses to not do anything.

So I though, why the fuck not be altruistic ? My hair will grow, some people won’t have the grace or the beautiful act of feeling hair. So I though why not give it away ?

So I did. And now my hair feels very weird. I don’t like the cut. They cut like maybe 25 cm. And that’s it.

I ate something. Good bye. Maybe I will sleep soon.

You shook me all night long. AC / DC

For those who were not in Mexico at the time, apparently the Earth trembled. It shook.

The epicenter seemed to originate from Zihuatanejo, Guerrero. I hope everyone is fine. I definitely felt it here in Toluca, several hundred kilometers away.

Weirdness of entropy or the Absurdity of Entropy.

note: my friend Gaby thinks that I did not touch entropy enough. Fair enough, I don’t really dive into the definition or the concept.

Okay, so I just got back from Veracruz. As usual, I am procrastinating and not doing my calculus assignment; instead, I’ll tell you about a story about entropy, destiny, and I do not know what else.

Okay, so I was in Veracruz, up until Saturday. On Saturday I went away - with my family - to Tlaxcala, about halfway to where I live. On Sunday we continued the route and got to my house. Then we unpacked, my parents told me to actually get all my stuff up to my room so that they wouldn’t take up that much space in the house. Then we rested for a little bit and went away to eat, since there wasn’t much food in the house. We had been away for about a week.

Then, while we were in the car, I realized I was not wearing my seatbelt. Weird thing was that this SUV always beeps with a very fucking high pitch when someone does not have their seatbelt on.

But how might the vehicle detect if someone is not using their seatbelt ? Well, the seatbelt buckle is made of metal, so maybe there’s two terminals in the seatbelt socket that close a circuit. And it only beeps if there’s weight on the seat. But the thing is that if you’re already in the car - without your seatbelt- and then you start the car, the car will think that you’re just a load, meaning it won’t complain if you do not have your seatbelt on. All of this I am assuming from my very few experiences in this SUV, in (or on?) the passenger seat.

So, anyways, I am going out to eat. In this car, with my family. I do not have my seatbelt on. Then I think, what are the odds that we crash while I do not have my seatbelt on ? Hmmm, who knows I think. Just a not-so-odd thought that popped into my head. All of a sudden, a car from the other side of the road - who was going in the opposite direction - just turned and gased the pedal and went into our side of the road while my dad was going through a green. I think she wanted to park but wanted to have better visibility when exiting. So she ( I think ) was going to go left, would then backup and align to the parking spot. Which is- as you might expect- perpendicular to the road.

So then my father pressed the brakes so hard that I could have died. Nah, just joking, I don’t think I would have died. Maybe if I had been in the middle seat. But I was on the right-passenger seat. Without my seatbelt. So my reflexes came in and I just started to try and make tension with my legs and push towards the copilot seat so that my legs would take the force of the sudden breaking and I wouldn’t have a bruise on my head. So yeah, that’s that. Then my father started to bash the horn so hard that it was probably heard on the whole intersection and maybe several meters away.

yeah, entropy is so fucking weird. What was the probability that whilst I was thinking the probability of being in a crash whilst not wearing my seatbelt I would crash ? Probably a whole fucking lot. But hey, maybe math or statistics people will tell me that I’m an asshole for not wearing my seatbelt because the probability is reasonably high because just look at the birthday paradox. The probablity that 100 people will have the same birthday is super high even though there’s 365 days to choose from.

I do not know what else to say. Maybe I will blog later in the day, I will try to stop procrastinating now. arrivederci, my dudeees. ( my fork of the it's wednesday my dudeees... vine ).

Writing math in raw utf-8

Posted on:	04/17/22 00:33:01
Last edited:	09/27/22 10:17:13

on web browsers and GUI apps

So apparently linux lets you use the keybinding Ctrl+Shift+U to insert utf-8 characters, literally any utf-8 character. This is in a non-terminal application such as libreOffice, Chromium, Firefox, etc.

Why does this work ? No idea. Don’t know if this comes directly from the kernel - or X11 / xorg - but yeah, it works and I can type stuff like:

1 + 1 = √2

yes, that’s a square root symbol in raw unicode ! without using microsoft word with a laggy interface or whatever.

utf-8 symbols on vim

On your terminal, it’s quite hard to type them. the only reasonable way is copying and pasting this character.

Anyways, if you are writing in vim, you should be able (by default) to write utf-8 symbols in insert mode by pressing CTRL-V, yes Ctrl and the letter v. Now you should be able to type u for unicode and just write the unicode code for it. After you finish writing the code, the character will appear on screen.

If it isn’t appearing or you just see random whitespace, most likely your terminal does not have the correct font installed or just neglects that character.

vim example

e.g. to write the capital letter E with a grave accent È you would do the following. First, you’d find that the code is U+00C8. The hexadecimal code is 00c8. Now you’d go into vim, get into insert or replace mode ₇, then type Ctrl-V, then type u, then type the hex code 00c8. After typing it, the character should appear on-screen in your terminal!

Cool!

Now, I should add that i found a vim plugin.

vim plugin

it kinda sucks https://github.com/chrisbra/unicode.vim tbh

some unicode tables on wikipedia that may be of use:

• tiny numbers and letters! Subscripts and Superscripts
• Latin 1 Supplement accents, grave, acute, dieresis, pretty much write in Spanish
• Phonetic Extensions self-explanatory.

so we now have a new domain !

unless you read the mediagoblin post, read this !

visit me now @ blog.thetrevor.tech to see my blog ! instead of the long kinda fishy domain duckdns.org. Although it was a great start I now use thetrevor.tech.

I acquired it for a time of one year - for free btw. And the whole domain is mine !

so yeah, I could write thetrevor.thetrevor.tech or literally mydomainforoneyear.thetrevor.tech point is, I can now share my site just as thetrevor.tech and they’ll see the main page of my site.

same as https://trevcan.duckdns.org/

so yeah.

I got this through one of the github education offers with the Dot-Tech domains company. By the way, I wasn’t even able to change my account password. This startup seems kinda fishy, but hey I got a free domain ! Their support never answered me. the domain interface is weird and ultimately, I do need https://duckdns.org since it’s what anyone who accesses https://thetrevor.tech has to check since in the DNS record is literally just an alias to https://trevcan.duckdns.org.

And right now I don’t want the hastle of setting up a nameserver system. Since that’s what https://trevcan.duckdns.org is acting as! dot-tech provides some name-servers which I could in theory use but I don’t think they have an API to rapidly change my never-changing ip addresses.

So that’s that.

I’m leaving some links below as well on some things that helped me set it up.

Also, you may now check my re-styled CSS git repo !
now available @ https://git.thetrevor.tech !

Why do I sound like speaking broken english ! who know ? I don’t speak like this, I hope.

tldr

• new domain: thetrevor.tech
• https://thetrevor.tech
• https://blog.thetrevor.tech
• https://git.thetrevor.tech

I hope that by the end of this week I’ll have a videos.thetrevor.tech set up so I can upload any of my youtube videos to my computer and let anyone stream them from anywhere.

I’ll probably be using peertube, it uses torrents, among other things; so I hope it doesn’t saturate my network.

Maybe I’ll promote my blog, but I don’t have any good ideas yet.

I also plan on explaining how I set up my website, from top to bottom; including my blog.

okay so bye.

Nothing new, I guess.

Why am I making this blog post ? Well, I’m dumb. No, I’m not dumb. I’m just trying to have an inner conversation and some kind of introspection to understand what is going on, man!

Why am I like this ??

Why do I self-sabotage ( is it with j or g ? oh yeah in english it’s definitely with g, right ? ) ??? !!!

Don’t self-sabotage Hector!

You promised Tim that you’d be good enough and work on time. He has been nothing less than tolerant with you ! And that’s a good thing. Seems like a nice guy.

Honestly, some people warned me that it could be a scam and that I’d be tutoring for free whilst he’d be selling ads on the discord chat or whatever. But it isn’t a scam!!

This person is real. He works a real job. Kinda boring, but not boring to death. But he created this foundation that helps highschool kids learn programming and also career-changing adults to learn technology and get into coding jobs.

So that’s good. And I’ve met good people. Yet I have barely done any work.

I promised Tim, I promised some friends I’d do stuff; yet I haven’t done it !! Why, hector ?

Why are you still here ?!?! just writing this shit out on the vim text editor which you think is cool because george hotz (a.k.a. geohot or t0mcr00se ) talked about it ONCE on a recorded live stream that you did not pay for and now I use it ! But it’s cool because I’m a Linux guy, right ? I think I got into Linux because of George, so thanks for that george. And george was also the guy who introduced my to tiling window managers when I was first starting out with Linux.

I tried out XMonad, actually.

But again, why the fuck am I still writing here !?!?!?!

Just get to work, man! don’t try to get people’s attention if you don’t deserve it.

No, fortunately I’m not suicidal. Am I a pathological liar ? No, I am a doer. Hector, you are a doer. You promise stuff.

When you don’t achieve it, you should be honest with yourself and with the people you promised it to. You should let them know that you’re a procrastinator - a professional procrastinator. Oh, God! WHy would you even say that you are a professional procrastinator.?!?!?!?

What the hell does that even mean !? No, man. You are sabotaging yourself, your relationships, your careeer.

Calm the fuck down, Hector.

Put your server on a fucking etc/hosts file and get over it !

Just to brag, this is my /etc/hosts file right now:

# Static table lookup for hostnames.
# See hosts(5) for details.
127.0.0.1   localhost
::1     localhost
127.0.0.1   t490-4rch.localdomain   t490-4rch   
0.0.0.0     news.ycombinator.com
0.0.0.0     lobste.rs
0.0.0.0     wikipedia.org
0.0.0.0     en.wikipedia.org
0.0.0.0     web.whatsapp.com
0.0.0.0     duckduckgo.com

that is all. Maybe i’ll add my server here after pushing this blog post and just ignore it.

Today, I’ll try to as be zen as possible.

Don’t even spell-check this shit, man.

Mistakes are made, and you probably aready know that I’d have corrected them or maybe I did not or ma8ybe I will.jjj1

MediaGoblin won't work.

Last edited:	04/11/22 01:46:04

Hello. I have recently acquired a domain for some time, called ‘thetrevor.tech’ and you may not visit my site using that domain name.

e.g. https://blog.thetrevor.tech. Yes, I kinda own the whole domain! I now have a revamped git repo at https://git.thetrevor.tech !

Anyways, I’m getting very off-topic. For some time now I’ve been wanting to have a video streaming platform that allows you to view videos from my server, without youtube or vimeo or peertube or whatever. I found about peertube through Luke Smith’s instance in which he hosts some exclusive – yet still free - content.

Which sometimes forced me to instead go to that site instead of youtube since sometimes he just won’t altogether post any new videos on youtube but will on peertube.

I also knew about odysee through Mental Outlaw. Not that mental outlaw is bad or anything, but I don’t like that much the decentralized platform that consumes a ton of resources on your client web browser and will just lag even on a moder web browser.

I like luke’s peertube instance. It’s fast and stable. even if it uses webtorrent ! Plus, I can download the files and the interface doesn’t seem so bloated – although this may be just my bias but whatever…

Anyways, I haven’t even talked about the title of this blog post yet! Have I now ?!

Ok, so the Mediagoblin deployment is not working on Arch Linux ?

Why ? because why not I guess.

But what is MediaGoblin ? Well, it is an attempt at making an un-bloated self-hosted streaming video platform.

But it just won’t install on Arch Linux. I don’t know.

I followed official guides on how to set this up yet it won’t work.

There are apparently documented issues that show that this is, indeed, an issue specific to some Linux distributions and the autoconf package! Why… and that’s made by GNU! so get ur stuff together, GNU!

this is the official bug report from the GNU Mediagoblin issue tracker:

https://todo.sr.ht/~mediagoblin/mediagoblin/12

ther useful links:

• https://docs.mediagoblin.org/en/master/siteadmin/relnotes.html
• https://mediagoblin.org/pages/join.html
• https://docs.mediagoblin.org/en/master/siteadmin/help.html

• old guide; https://web.archive.org/web/20201116055028/https://wiki.mediagoblin.org/Deployment#Lighttpd

So yeah. Maybe I’ll try setting up peertube or something.

Resizing images on Linux while keeping aspect ratio.

Posted on:	04/11/22 01:43:36
Last edited:	04/11/22 01:43:36

bored ?, read [0].

tldr

convert FILE -resize SIZE OUT_FILE

convert image.jpeg -resize 300x new-image.jpeg

( resizes image.jpeg to 300x width, scaling height accordingly and writing it to new-image.jpeg)

Where FILE is the input image file you’d like to resize, SIZE is the new size in pixels, e.g. 500x will set a 500x width and scale the height accordingly whilst keeping the aspect ratio. And OUT_FILE is the output file. No, it won’t modify the original file.

That is all. oh, no. Dependencies!!

Sometimes the truth hurts

Yes, sometimes the truth hurts.

Especially if you have something to do with it.

Truth is weird. Humans lie. I try not to lie. I try to be plainly honest most of the time. I try not to cheat on exams. I try not to look at the exam answers even when my friends would give them all to me without any academic repercussions.

But when the truth affects your past, your situation, your view of life. You kinda die inside. You oughtta accept that sometimes you just aren’t right and maybe you’re fucking wrong.

I fucked up, I guess. I think that you were definitely right, Gaby. No problem. But it is hard accepting the truth.

End.

why ?

why not ? the main reason I put this here is because it was on my phone just taking up space.

I extracted this information from Lex Fridman’s Podcast with George Hotz.

Un escrito que me encontré en la web

Posted on:	04/08/22 13:43:33
Last edited:	04/08/22 13:43:33

Hola, este es uno de mis primeros posts en español. Este es un texto originalmente publicado en 0.

Decía Schopenahuer que una vez quedan resueltas todas las necesidades que la “voluntad” exige a las personas, a estas no les quedará más en la vida que el sinsentido, el desánimo, el ocio. La necesidad, el deseo de algo, es aquello que dota de propósito, rumbo y significado a nuestras existencias. Por ejemplo, si no sabes qué hacer con tu vida ten hijos y obtén un sentido para tu existencia, uno dado por default biológico.

Al mismo tiempo, filosofías como el budismo enseñan que estos deseos que la “voluntad” impone, pueden representar la cárcel de nuestras consciencias individuales.

El vagabundo y el despierto tienen algo en común: son seres marginados de los parámetros sociales; el propósito y significado de sus vidas es sobrevivir a la incertidumbre de encarar su propia existencia.

Es una cuestión de perspectivas: afronto el sinsentido de la realidad haciendo conscientes mis deseos animales, o bien, soy feliz con el breve goze que me brinde la satisfacción de mis necesidades y pulsiones, al igual que el traidor en Matrix elige los placeres de un mundo ficticio que despertar en la crudeza de una realidad que no le brinda satisfacciones externas.

Podríamos decir que la sociedad del siglo XXI ha resuelto sus necesidades básicas, al menos en la cultura de occidente, pero tal como indica la piramide de Maslow, hay luego otras necesidades tanto afectivas, de autoestima y autorrealización. ¿Vivimos en una sociedad que nos alienta a realizarnos y encontrarnos a nosotros mismos?

Creamos un mundo que enaltece la competitividad con otros seres humanos, que romantiza la meritocracia, al mismo tiempo la ansiedad y depresión han alcanzado picos tan altos que lo que consideramos una moda en realidad se trata de una epidemia. ¿Coincidencia? No lo creo.

Ya nuestras necesidades de simios salvajes están resueltas al punto que ahora llegamos a buscar la satisfacción del capricho, del simio vanidoso y las necesidades inventadas por el marketing. Ahora afrontamos de cara el vacío, la inseguridad de nuestros egos. Ya no hay que salir a cazar ni ir a la guerra, ahora enfrentamos nuestra propia soledad frente a un mundo que no comprendemos, pero al que tratamos de adaptarnos desesperadamente mediante sus estándares de “éxito”. Quizá por eso buscamos el mayor número de distracciones posibles, al igual que el citado traidor en Matrix, que le doten un sentido artificial a nuestra existencia: el placer, el aturdimiento de los sentidos.

Y todo este paradigma no es sino un nuevo mercado que explotar: el mercado del aburrimiento, del vacío existencial que busca satisfacerse con un iphone de miles de dólares; la avalancha de series, películas, videojuegos en las que olvidarnos por un día más.

Escrito por: no sé.

Querying Netflix media by genre codes

Netflix genre codes

The following explanation is in Spanish. Should be pretty self explanatory even for non-Spanish speakers.

just replace the code in the urls for the ones you’d like to search for.

Van a poner en la barra de búsqueda de su explorador https://www.netflix.com/browse/genre/ Después del “genre/” van a ingresar el código de la categoría que quieren ver, ejemplo:

“Steamy thrillers” o sea misterio cachondo el código es 972 ergo en su barra buscadora van a ingresar: https://www.netflix.com/browse/genre/972 Y ya ahí les va a salir un catálogo que incluye -Basic Instinct -Addicted -Sliver, etc, etc.

HTTP Proxy

Posted on:	04/07/22 21:53:42
Last edited:	04/07/22 21:53:42

I have a problem. I’m a linux junkie. I’d like to ssh into my home-server from any network. This means networks that don’t allow port 22. My institution’s network only allows port 80 and 443 (and maybe vpn ports).

So I think what I need is a proxy server. A proxy is what is sounds like. It’s an intermediary between me and the target server. But it can work through http and use other protocols (in theory).

useful links

• tunneling http thru ssh
• proxy server. wikipedia

• docs mod proxy
• lighttpd reverse proxy
  • lighttpd as reverse proxy

• corkscrew.

• guide: using corkscrew to tunnel ssh inside https
• guide: http thru ssh

I tried doing some of these but was, unfortunately, unsuccessful.

Maybe if I try this with an apache web server it might work, but who knows !?

just about four minutes ago I stumbled upon a good friend of mine, Nacho. He was with her friend, Betzabé. I couldn’t remember the name. Nor did she remember mine. So we did not salute. Then Cindy arrived. I did remember Cindy’s name. Then I asked them about where the Auditorium 1 was. Apparently I had fucked up. It was in the high school building, not in undergrad. Then I told Betzabe hello, and sincerely said that I couldn’t remember her name. “Betzabé”, she told me. She confessed she didn’t remember mine either.

So this story / blog post shall be meant to be used for future reference when trying to remember Betzabè’s name. Betzabé. Betzabé. Betzabé. Betzabé. Her name is Betzabé. Almost all of the times I’ve encountered Nacho I’ve also encountered with Betzabé. Weird name. Three syllables. or Betza, maybe ? Nah, I’ll confuse her with someone who’s actually referred to as Betza. Are you though ? Are you referred to as Betza, Betzabé ?

Who knows, lol. Just a fun story I felt like writing I guess. Back to the always-late-cause-we're-inmexico-and-stuff.

Git server upgrade!

Posted on:	04/02/22 22:14:30
Last edited:	04/04/22 17:59:55

So, as of yesterday I was running a git over ssh server. Which isn’t even a server per se, since it just runs software that was already installed on my system. (ssh)

But this approach isn’t very useful. It does not allow me to update my git repositories (including my blog) through restricted networks, such as the institution I study at. Port 22 is indeed restricted.

So I thought, I’ve always seen that https/ssh/zip button link thing on github. Why can’t I do that ? Isn’t https like allowed on almost any network ? So I started investigating.

According to the git-scm [0] reference manual, there are other ways to host servers. One of them is using a CGI script that runs server-side.

CGI stands for Common Gateway Interface. It’s a standard protocol that is to be run server-side to provide HTTP content on-demand. Most popular webservers will provide plugins to run CGI scripts. This protocol takes a few environment variables and just returns the HTTP response just as if it were a server. In the future, I’d love to make my own ‘CGI Server’.

---

So I tried to set up my lighttpd web server to route all requests for the domain https://git-push.thetrevor.tech/ to the CGI script.

I must say, this was a pain in the ass, but this is my working configuration file.

https://git-trevcan.duckdns.org/lighttpd-conf.git/tree/sites-enabled/push-git.conf

when i have the time i’ll explain it over.

please don’t hack me.

Actually unmounting and removing power off HDDs

Posted on:	03/30/22 18:19:42
Last edited:	03/30/22 18:22:39

On windows 10, when ejecting a hard disk drive, it will stop spinning. That is nice. It, of course, unmounts the partitions before.

Linux does not do this automatically, at least not my minimalist setup that only uses dmenu,lsblk,mount,umount and a little of grep/sed/other text-editing tools.

When unmounting a drive using umount it merely unmounts the disk partitions. It DOES NOT manage power, as far as I know.

To remove power from the HDD, I use a tool named hdparm, used to set HDD parameters through the shell. The package should be installed by default on archlinux, this is the project page (it has adware).

Anyways, to set the HDD params you need to be root. I don’t know how to set the permissions so that a normal user can do this, but I’m not interested in learning how to do that cause if an attacker gains command execution on my system I don’t want them to have access to managing my HDDs power.

I use this script:

    timeout 10s prompt "Remove power from $1 ? " "sudo -A hdparm -Y $1" &&
    notify-send "$ dmenuumount" "Power removed from ${1}. You may disconnect it now."

the important part is hdparm -Y "$1". This flag -Y (yes, capital Y) means put the device in the lowest possible power mode. It will still be listed under lsblk but it will turn on once you actually want to mount it. the "$1" is the path for the device, e.g. /dev/sde.

As noted before, you must be root. BE SURE to check the device, since running this command on any devices you are using could fuck up the system!

questions ? contact me.

Finding empty directories

Posted on:	03/30/22 17:53:43
Last edited:	03/30/22 17:53:43

based on this article: https://www.linuxshelltips.com/find-and-delete-empty-directories-in-linux/

Problem is: I have a linux shell script that lets me mount hard drives, usb, and other storage devices. But if I have already mounted some storage device and it has a lot of folders, my command will keep looking for empty folders where other storage devices can be mounted. In other words, I have a directory /media/ where all the folders for external devices are created. I mount my big HDD with a ton of folders to - let’s say - /media/HDD_0. Now it is available and there are thousands upon thousands of files available under /media/HDD_0. Now I want to mount another device. What my script does if find empty folders under /media/ but it will find it recursively.

So the solution is using the -maxdepth n option for the find command. This allows you to set a maximum depth in which to look. Pretty self-explanatory, right ? So in other words, if I give find a starting point of /media/ it won’t go more than n folders recursively. That’s it.

Yeah, I use the LARBS voidrice dmenumount script, apparently the github does have a max-depth but I think I removed that because I only wanted to look under /media/.

But hey, I fixed it with the magic of the internet and reading man-pages and at times bashing my head at my own hands or arms.

I am addicted to hacker news

Or maybe I am just too much of an asshole to want to talk to my friends.

I don’t have anything to say. I’ve recoursed back into using my phone more often, and not leaving it behing. I used to leave it behind when going to the bathroom, for a walk or just for anything, actually.

Yet today I was very worried. I really liked someone, I told her that I liked her but she was in shock. I didn’t see her again until like four hours later. I tried to talk to her but I guess she didn’t want to.

So yeah, she does not like me. Yes, indeed.

Anyways, that has somewhat something to do with the black points over the orange background. Yes, I am referring to hacker news. Specifically, the points I have accumulated on my profile [0].

I’ve noticed that I do not enjoy reading the orange news anymore. Every once in a while - more like a shit-more often than before - I’ve clicked on the new section of news. Meaning, even news aren’t ‘that’ ranked but they appear almost as they are submitted by users all around the globe.

But I don’t even find the normal hacker news ranked content nor the show nor the ask nor the newest news hacker news relevant to me anymore. Yet I check and check and check and check and check.

A few interesting articles here and there, but I don’t finish them. They kinda bore me to death.

Fortunately, my relationship with that person I was talking about is fine, but yeah she’s told me that I am not liked by her. But she’s a very good person and by no means I would like to ruin our friendship. You are a good friend Astrid. You too Fatima, for reading my blog and being there and teaching me chinese.

拜拜

I hope that means bye.

Small community. 200 blogs ! oh my god, that’s nothing! Anyways, eventually I saw one of the top blogs and stumbled upon waitbutwhy.com.

The articles seem promising, I read a couple but got to the middle of each one and then left. Eventually, I clicked on the ‘about’ page and started reading the ‘wait but who’. Very meta web-site. This about page acknowledges the hurdles of maintaining a website whilst working a (maybe?) full-time job.

Debugging Linux chown operation not permitted

Posted on:	03/27/22 21:02:58
Last edited:	03/27/22 21:09:39

yes, even for root!

Main reason this happens is usually the permissions themselves.

If you ain’t root you won’t be able to change an external hard drive mounted without custom permissions.

TLDR; become r00t (root) !

TLDR 2; or just RTFM and man tf outta mount!

man mount

wait, you didn’T solve my PROBLEM!!

well, then, you are in some luck. You probably have a file system that doesn’t allow permissions. These file systems include fat, vfat, fat32, and others. These file systems may complain when trying to change permissions, so just chown the root directory in which your external storage device is mounted at and you’ll probably be good to go in order to add files without being root.

That is all. Thanks for reading my ted talk.

You are a human being. the fact that you are still here says a lot: You are more important than someone or something else. You are here because you survive. You overcome. You adapt.

Hello. I woke up several times and tried to sleep and turned off my shitty alarms.

Eventually, Joe called. I answered. I understood, my voice was clearly fucked up. I think I’m dehydrated.

Then an alarm started to sound at the same time I was taking the phone call ! What a silly design choice, Apple ! Then I woke up, went to the bathroom, tried not to die.

I then started committing a lot of changes. Then I pushed. And I pushed.

I got 500'ed by github. What a shame. Github is my go-to remote git provider. It works over https, aka firewalls don’t tell me no. I had some respect for Github.

But I had to push this as fast as I could. So I ssh'ed into my home server, then created a bare git repo and pushed to that.

Since my friend is in a proxy plus firewalle’d network, he couldn’t use his ssh keys so I sent him a link to this:

https://git.trevcan.duckdns.org/RobotCode_2022.git/

And that works over https ! Push doesn’t work over http/(s) but yeah. He was able to pull in no time and could get my code. So that’s good I guess.

Dedication is not only admirable, but achievable

Posted on:	03/21/22 02:44:58
Last edited:	03/21/22 02:44:58

Yesterday - well, technically the day before yesterday a.k.a. antier in Spanish - me and some friends were sharing stories of how we got into Tecbot, the robotics team I am a member of. We were tired after a long day of working, testing the robot; building stuff; realizing that X or Y doesn’t work; trying to find x or y thing for this problem; then realizing again that it was there the whole time behind some backpacks or whatever.

Anyways, we got to this kid. His name is Velasco. He is in 2nd semester of high school. In other words, he’s a freshman. He tried to get into tecbot since middle school, in 9th grade. People referred him to X teacher. Teacher did not respond his emails. None. Nada. none at all. Maybe his institutional teacher account had some corporate spam email filters so maybe he never actually received it ! So he got tired and eventually got into the high school were the robotics team was.

But this was all during the pandemic so he barely got to be in the high school buildings.

He tried emailing him again. And again. He seemed busy. He did not respond. Yet Santiago figured out the name of the teacher, then ( somehow ) got his zoom handle and started to get into his meetings at random times.

Eventually he figured out at which times he had to give classes and at which times he actually gave Tecbot. The head coach, X, is more like the manager. He knows some things here and there, I think he’s an engineer but hasn’t practiced in a long time. He isn’t actually one of the mentors giving technical advice - well, sometimes he actually is. So Velasco eventually figured out who the mentors were - that’s what we call them - and started to take electrical courses. This includes from resistance, raw formulas to actual real wiring of the robot, soddering, managing batteries, cables, and a shit-load of other things.

For this Velasco, I admire you. I somewhat remember when I got into tecbot. But I don’t think it was this hard for me. I actually tried getting into tecbot at the same age as you did - when I was in 9th grade. But it wasn’t this hard. My best friend had a brother who was attending that high school and that robotics team. He was - at the time - the season driver ! So yeah, I was able to get in pretty easily. But I very much appreciate that you are now in the team.

You told us and made us realize that showing up and doing things is more important than being on a list. There was never and will never be any list. If you have enough dedication to go through all this and more, you can and will and are going to be able to do anything you want.

This post is for you,

Velasco.

Lazy man's VPN or Simple VPN through SSH

Posted on:	03/16/22 16:00:48
Last edited:	05/25/22 21:44:35

It works like a VPN, acts like a VPN, feels like a VPN; but it kinda isn’t a VPN.

Would you like to access your local network ?

Are you too lazy to set up a real VPN server like me ? Do you like security ? Well, now you can use a virtual private network through ssh and route all requests from one machine to another, using sshuttle.

tldr

commands:

sshuttle -x server.org -r user@server.org 0.0.0.0/0 --dns
sshuttle -x server.org -r user@server.org addresses/subnet --dns

WHERE:

server.org is your (ssh-enabled) server’s domain name.

-x server.org means, exclude the server.org domain from being routed through your server (server.org), the wiki says some problems occur on some linux machines - it will recursively resolve to itself and the ssh session will crash.

use 0.0.0.0 on SUBNET to route ALL requests through ssh server.

use 24 for subnet and use 192.168.1.0 on addresses to route requests starting with 192.168.1. through the ssh server.

e.g. sshuttle --dns -x server.org -r user@server.org 192.168.1.0/24

I never created a solenoid object. If I don’t use pneumatics, the thread to keep the compressor at the necessary pressure will never start.

Hello there. I use spotify. My dad pays for it.

It allows me to listen to almost any popular artists and songs, even indie creators are there to! I do not use the podcast features.

I doubt that I have found ‘good’ songs through Spotify ? But I might be wrong. My liked songs playlist is like 215 songs long, not bad I guess.

But yeah, a lot of consumption. Remember what happened to spotify like less than a week ago ? Well, let me remind you. Spotify servers went down for whatever reason.

You open the app, your phone is connected to the internet. You want to listen to some downloaded songs. The app pings the auth server, doesn’t respond; logs you out. You are now unable to access any of your spotify music.

YOUR. Yours? Your music? Really yours ? doesn’t sound like it. You weren’t doing anything wrong. You are a paying customer who gives them money on a monthly basis through a platform that allows you to download songs and audio. But restricted. You were not pirating anything. Yet you were gated by the same company who built the software.

Were the devs instructed to do this ? I certainly hope not. And if they did that on purpose, with all due respect, shame on you !

Ok, so enough backstory I guess.

For a while now I’ve been wanting to make myself more independent from software I use. So I though about downloading all the music I have saved on spotify.

I can’t easily download them from Spotify and decrypt them. Or maybe yes ? If so, please let me know.

Anyways, I eventually found some services which charge you for using the spotify api to retrieve a list of all your playlists. But then I appended ‘github’ to my search query and lo and behold, we have exportify!. It’s an open source free project that allows you to export any of your playlists, either imported or created by you! You can export all of them in bulk, or one by one if you prefer.

All the code runs ‘in the browser’, at least according to the git readme.

It is served ‘statically’[0] through github pages @ https://watsonbox.github.io/exportify/.

the website needs javascript and an internet connection for it to work. It will connect to the spotify api.

Ok, so then I exported all of them, unzipped them.

CSVs. hmmm. comma-separated values. simple enough I guess. With a shit-load of boring spotify links and the title and artist. All I need.

Song title, song artist. That’s it. After a few makefiles, some rambling around with zsh and bashisms and weird shell syntax, I got awk and tr to work for me.

todo: add makefile here or somewhere

Ok, so once I got all my playlist songs, I converted each of them to whatever I wanted.

Then I used yt-dlp (fork) to download the videos by appending the artist name to the song, and using its own search engine to query from youtube.

so the code looked like this:

yt-dlp --default-search ytsearch: "$SEARCH_QUERY"

and I did that for each song. And i added a couple flags here and there to tell it I want aac files and metadata about the songs/videos.

It took hours. Mainly because youtube detected that I was downloading a shit-load of youtube videos and it wasn’t normal.

Sometimes downloads were around 10 MB/s (yes, megabytes) but then they circled down to maybe 700 kB/s or so. The popular songs were the ones that got stalled.

The total size of all my songs and saved playlists on spotify was about 20 GB. Then I targzipped the shit out of it and got 18GB. Still a lot.

This was in the morning. I went to school. I couldn’t use up 20 GB out of my cell phone data carrier! Plus, the speed would be shit.

So I had to figure out a way to download it through my institution’s internet connection. Web server. I have a web server, a blog, and some other stuff. I have directory listing enabled in some places. Yay.

I logged into my web server through ssh using my cellular data - because my university has the port 22 blocked and won’t allow me to ssh into my server - and proceeded to move the tar file to a place where it could be showed by the web server, publically.

Of course, if you want to sue me. Just know that this falls under personal use and no, I am not profiting from downloading these songs.

I am still paying for the same services I was paying before. Please don’t sue me.

Anyways, the tar.gz file was public and now was my computer’s time to shine. I’m on Linux and the download speed are incredibly good on my uni’s internet. When I’m on windows 10 they appear to be stalled for some reason ! No, I don’t know why.

Well, maybe because the servers for the school run linux or something.

I don’t know. Point is, I started a wget command of the tar.gz file, I got a stable 10 MB/s, going up to 15 at times. wget said it would be done in about 2 hours. I was in my car. This was perfect.

Then I guess a sysadmin caught me or something. A stable connection to a server with around 10 MB/s for more than 10 minutes ? I was over https, so I guess they didn’t catch whatever I was downloading. So they started to stall the download. wget showed literally — where the speed was. Actually, it first started slowing it down to maybe 8, then 7, then six and five and four and three and one and two MB/s. Then to the 50x KB/s, wow. sometimes it didn’t respond at all. Other websites worked fine through a web browser. Speed was fine. It was probably a sysadmin blocking my connection. I cancelled the download. I restarted it. Same problem.

So I started capping my download speed to 2 MB/s through wget. Fair enough. Other people have more important things to do with these glorious internet that sometimes gives a 300 ping on websites, but sometimes just a couple of milliseconds! so I capped it. And the sysadmin or network guy or automated program kept stalling my download ! To like 300, then 500 KB/s. It was like a cat and mouse game. I was at 2 MB/s for a stable minute, they got catch of it. Started to lower it to 1.5, 1, then 500 KB/s or just stall it completely. But it was basically oscillating between 500 KB/s and 2 MB/s. Constantly, so yeah.

By that time, I was at lunch. Then I went out and left my computer downloading the file with my friends. Eventually the computer started to complain.

It was almost out of battery. I was not there. It had less than ten percent and it was beeping, I programmed it to do that. Thankfully. My friends started asking questions to my computer as if it were a human being.

All my computer did was beep, beep, and beep. The beep was consistent. I laughed at the story when I arrived. If I had arrived maybe 15 minutes later, it would have reached 0 and would be dead. Actually, my Lenovo T490 kills itself like at 2% and does not allow you to turn it on. Well, it turns on at 2% but like 5 seconds later it dies. So I was kinda just in time to charge it. So I went inside, to the tecbot workshop to charge my computer. I brought my backpack with me, as my charger was there.

Computer still not dead. Started charging it, all good.

then I went back to eat with my friends on some benches.

In total, I’d say the download took around five hours. Maybe six with the first download. I reached like 15-20 % in the first one! I don’t know why I stopped it and started re-downloading it again.

So yeah, 18 GB of targzipped tarballed music. Started de-compressing it.

I didn’t have enough space. I cancelled it. I connected my hard disk drive.

three tera-bytes. nice. I copied the tarball there and started decompressing.

It did take a while, maybe ten minutes at most I’d say. Not bad I guess.

After that, I had shit-loads of music. But at the time of writing this,

I haven’t even put all the music onto a USB. i don’t think I have another one big enough for 18 GB worth of a lot of music. I could plug in my hard drive. But the partition where I saved it at is ext4. I doubt the volvo I drive will be able to read that. Plus, I don’t want to fuck the HDD up. Constant turning on and off, probably the disk spinners are not properly set to ‘power saving’ mode when turning off the car. So no thanks. Maybe I’ll use the usb I have for operating systems. 32 GB. probably less usable storage. whatever.

I have an 8 gb spare usb, maybe I’ll transfer the most important oses to it.

Ok, so now I have a shitload of music. I feel proud of myself.

I can even browse it through directory listing using http(s! included but not enforced!) but it won’t autoplay.

Maybe I’ll look into creating a .pls file or a .m3u8 file for playlists. They allow for absolute paths, not necessarily a server audio stream. so yeah, I should make some code for that.

Also, the volvo I use does not allow a lot of media formats. It does accept mp3, but I didn’t have that. yt-dlp downloaded everything in opus, the first time I did tests.

Plus, the usb needs to be in fat32. I reformatted the 8gb usb just in case - it was already fat32. Then i copied some of the songs I had downloaded on my computer. Before the big ‘all playlists’ operation. But yeah, did not work the first time due to audio file types. All were in opus. So i converted them to mp3s or something and it worked.

Here are some useful links that helped me through my journey:

• list of compatible file formats for volvo s60

• list of compatible file format for volvo s60. official

• specification for connecting external storage devices to the volvo. specifies file system for HDDs and usbs

• using awk to get csv fields
• what is awk ? how to use it.
• exportify spotify github repo. exports all your spotify music
• keep processes open after ending ssh session. tldr; use tmux

references

[0] I say statically in quotes because I tried copying the html to my computer and it didn’t work. I got some error when trying to get the spotify token and setting up the spotify auth, apart from the fact that the html paths for the scripts and css were absolute, so I had to change them manually.

copy all Pictures/Videos from iOS device to PC

Posted on:	03/06/22 01:14:58
Last edited:	03/07/22 13:47:02

This guide is a tutorial to learn how to import ( and optionally delete) and browse your pictures and videos inside your iOS Device. You only need a working computer, a lightning-to-usb (with data transfer) cable, and an iOS device.

non-features

• You do not need another, external iOS Device, you do not need to pay Apple for iCloud, you do not need to download laggy, iTunes windows-and-mac only software.

features

• you can browse all pictures and videos saved in your iOS Device
• you can delete any pictures on said iOS Device
• you can copy all the pictures easily.
• you can do this from a Linux / GNU + Linux / *NIX machine.

the software used will be libimobiledevice, a cross-platform software library used to communicate to iOS devices. ifuse shall also be used to enable filesystem mounting.

start

1. connect iOS device. Click allow for computer pop-up thing.

assuming usbmuxd service is active, use the idevicepair command to connect to your device:

$ idevicepair pair

yeah, the command argument seems redundant. You should get some ‘SUCESS: Paired with ’ and a long string of characters.

1. mount filesystem.

assuming you have ifuse installed, use this command:

# ifuse -o allow_other MOUNTPOINT

where mountpoint is an existing directory.

1. Access. Access your mountpoint. Keep in mind user permissions, you may have to chmod the directory beforehand to be able to gain access as a non-root user.

now you can enter the file system.

You should get a lot of folders when browsing the root dir.

The important folder is DCIM.

all pictures are there. Careful!

You can write to this folder.

delete photos

If you want to delete the pictures just do an rm -rf of the *APPLE folders under DCIM. Careful!

Pictures will still be cached in the device, so you’ll need to cause a database rebuild of your camera roll:

# cd <mountpoint>/PhotoData
# rm Photos* com.apple.photos.caches_metadata.plist

that’s it. you can also browse your ringtones, there’s a folder.

you can also write to it, but I haven’t found a way to let new ringtones appear in the list.

Right now what I do is generate a new one from garageband, choose a name, then import it. connect device. copy m3u ringtone to the dir and change its name to one of the custom ringtones. that works.

files?

I haven’t found a way to access the ‘files’ within the iOS File Manager. For now, I use this thing called ‘snapdrop’ to serve over LAN a couple files here and there.

that’s it! Something you want to add or critique ? Go ahead and contact me!

making this because sometimes i don’t RTFM.

Assuming you use the Network Manager daemon to manager network connections, follow this procedure:

go to this path: as root

/etc/NetworkManager/system-connections

Then try listing the directory with ls. you should see a list of *.nmconnection files.

open the files and there will be the password and auth specific stuff.

On Feelings

Posted on:	02/27/22 14:32:25
Last edited:	01/04/25 11:13:06

On feelings

today

Today. I woke up sunday twenty-seventh, twenty twenty-two at about twelve hours and thirteen minutes.

My parents attempted to wake me up earlier but were partially unsuccessful. I dont’t remember much about what I was thinking about whilst still in bed. Point is, I woke up. I went to the bathroom. Maybe I peed. I put water on my face and rubbed it in with my fingers, feeling the oil kinda come off and stick to my finger tips. I then washed my hands with my blue soap.

After that I checked my phone. Nothing important. Just messages that are kind of irrelevant to me on a Sunday noon. I then proceedes to go downstairs - to the kitchen. I then though about what to eat. The bread was out, in its plastic bag, beside the fruits. The toaster was not there. I walked into the pantry, not much to eat or at least that I’d be interested in eating.

Then I though, why not make some tostadas españolas ? And place a couple of sunny-side-up eggs on top.

tostadas españolas is a Spanish dish that consists mainly of raw garlic, tomatoes, and toasted bread. Like the bread you use for a PJ sandwich. You grind the tomato so you get this partially liquid, partially solid cream. You put in a bowl. I don’t filter out the seeds. I get some garlic teeth (not sure how you say it), you peel off the skin, cut each of them in half. Then toast the bread to your liking. After the bread is toasted, put on some plated, take the cut side of the garlic and spread it around whilst holding it with your fingers. Spread! The heat of the toast makes some of the garlic come off. Spread it all around like some marmalade / jelly.

Then put the tomato grinded cream on the toasts. That is a tostada española. As you may recall, I mentioned some eggs. Sunny-side-up. That’s how I like them. make them however you like them. Just place the eggs on top of the toasts and voilà!

You got yourself some tostadas españolas with a couple of eggs. Keep in mind to get the timing right. I did not tell you when to start cooking the eggs. But the way I did it was I started to cook them. then after about 20 seconds I started the toaster. By this point in time, I have already grinded the tomato and cut the garlics. I’ve prepared the plates. The toasts are now done after 2-3 minutes. I let them rest in the toaster, with some heat still coming off it. Eggs almost done, I’m turning the heat completely off. Now I go to the toasts, put them on a plate and start spreading the garlic around. Then the tomato thing.

Now I get the eggs ans gently place them over the toasts.

It is done! Parfait! Feast and eat!

then

after all that breakfast thing I washed all my plates and the cheese grater (which I uses to grind the tomatoes) along with my fork and knifes. Then I enjoyed some of the sun in my backyard, with some grass here and there.

After that, (I think) I messaged someone. They were busy. I was kinda stressed.

I haven’t actually talked to that person in a day or two. Then I decides to go watch a TV Show. But I remembered to take my stupid meds. I drank some water.

Then headed upstairs to the TV. Turned it on. Opened the app, prepared to click on the profile my parents arrived.

I had promised my father that I’d do some exercise. I haven’t done any. Yet. So I left the TV, took my phone and headphones. Put on some shorts, a t-shirt (I was in pijamas) and headed out to walk in my neighbourhood.

My Mom recommended I take the dog.

So I did. I was lazy to take a bag for its poop. But I mentally swore to myself that I’d go back for one when I was finished and pick it up.

So I looked for some sandals. It was sunny. I wanted sandals. I was wearing crocs. Good enough. I opened the door, called my dog, then headed outside and partially closed it.

Me, as I’m writing this:

i should probably take a shower, I’m kinda late for a family reunion.

Ok, so I started walking and was kinda sad about not being able to talk to that person before.

I started playing in order the Random Access Memories album from Daft Punk. I don’t think I’ve paid enough attention to all the songs. People say it’s very good.

So I listened to them. I skipped one song because I was kinda frustrated about the lyrics since it reminded me of some feelings.

Then I began to think about isolation. I hadn’t been this alone in a while. Just with my thoughts, music, and shit.

So I decided to make a ritual. An isolation ritual, just as I was walking.

That person is busy, so let’s just get our minds off that and try to be happy. I won’t be taking much care of my dog. I’ll let it be free. I’ll go for her poop later. It’s a gated community so she’ll be just fine.

Then I though about some weird religion which said to walk barefoot. Though about it.

Then thought about some cultures that put their bare feet no socks no shoes on burning charcoal.

It was hot outside. I was walking on pavement. Then I got to grass. I walked barefoot on grass.

It felt nice. All this whilst playing the RAM album from daft punk. There was a party yesterday. Seemed fun. I was scared yesterday to go say hi. Plus, I hadn’t been invited. I didn’t go to the party yesterday, yet it was so close! Like one minute away! -walking!!!

So I went to the back of the shared grounds with grass and plants. I found poop. A big one. Not from my dog definitely. It was dry. At least five day’s I’d say. But I mentally promised to pick this up.

I went to my house. Not for poop bag. But to take my crocs off and walk bare foot - no socks no shoes no nothing.

Just me and my feet with human skin.

The pavement is hot. It’s nice to feel my toes with the pavement.

It’s nice walking. It’s getting real hot. I’m probably getting blisters (ampollas for spanish, I hope).

who cares ? this is my ritual. What doesn’t kill you makes you stronger.

this is how my dog walks anyways. poor thing. But eventually I reached grass, decided not to step on any until the end of the road.

motivates myself to keep on walking (this feels similar to the Scatman’s World song!?).

I then proceeded to tho around three to four laps. That’s it.

It helped me calm down.

I wrote this partially in the bathroom. I don’t know why I’m writing this. Goodbye, I’ll go get a shower.

Setting up Cloudflare's DNS

Posted on:	02/15/22 22:03:55
Last edited:	02/15/22 22:03:55

A DNS stands for Domain Name System. It is simply a protocol for getting the IP address of any given domain name.

Usually, your Internet Service Provider (aka ISP) will provide you with one which may be a little slow, or even may block certain websites.

Below is a guide on how to set your DNS to Cloudflare. Any of these configurations can be (in theory) applied to all your network, but if you want there’s nothing stopping you from doing this for a single device (just search “how to set up DNS [device name])

DNS Cloudflare

https://1.1.1.1

1. For IPv4, replace the existing addresses with:
 - 1.1.1.1
 - 1.0.0.1

2. For IPv6, replace the existing addresses with: 
2606:4700:4700::1111

2606:4700:4700::1001

Hello there! Well, I was technically always here but guess what? My computer stopped working.

I think I messed up some docker (compose?) configuration and it basically adds an IP address to a network interface which should be the one for my local area network and my computer was probably confused where to route incoming packets but I kinda just did a quick fix.

not sure if it’ll survive after a reboot, since the problem has persisted (as of now) across reboots. But yeah we’re back.

Adding website stats

Maybe use webalizer ? But apparently it’s quite an old technology so it’s not easy to use. https://www.cyberciti.biz/tips/lighttpd-install-and-configure-webalizer-statistics-software.html

solution!

Don’t know how I did find it but it’s goaccess and it generates a nice html with graphs and numbers and works good enough.

You can access the current stats @ https://trevcan.duckdns.org/stats and a handful of other sym-linked dirs. Can you find them all?

It can give you the total number of requests among many other things including user agents and stuff. just random numbers but real actually.

Today: working towards an internship ?

Posted on:	01/15/22 18:08:27
Last edited:	01/15/22 18:08:27

this is probably a rant, discretion is advised but not obligatory.

Hello. It’s been a while since I wrote something public.

I’ve been in school - physically - and haven’t got much time to do stuff. Actually, that’s a lie. I’ve been in school but have gotten tons of free time. But let’s not shame ourselves, right ? I was supposed to start blogging just when I turned on my computer today.

But I just spent an hour with bloat on my computer. Opening chrome, converting an email to an image but first trying to save it as HTML but turns out the HTML is js-filled with shit that doesn’t even contain the email, then uploading it to my server (look, it’s live!.

and then thinking that I should set up a website that uses mediagoblin because why tf not? Well, because peertube is too fucking hard to set up. But maybe mediagoblin is too.

They got all these ton-shit dependencies. I mean, why the fuck do you need a MySQL-professional grade database running on my system for it to work. I’ve tried the docker instances for both mediagoblin and peertube but it’s just a lot of software stacks! I mean I’d love to have something like this showing my videos/ drawings, etc… but I don’t even know who I am.

Anyways, the point of this blog post was to write that I was going to try to do something to make my life better. The truth is, through my high-school journey I’ve been with a scholarship. Nothing to be ashamed of. But I fucked up. I’m a senior now and didn’t do anything good enough in terms of grades for school. I need to have an average of at least 85 to keep my scholarship through high school.

But to apply to another scholarship when entering college - yes, I’m staying there and i think it’s good enough - I must have an average of 90 as a minimum! Lame!!!

In other words, my dad’s shitting himself in debt because high school is already expensive as it is and in six months I’ll be in college and he won’t have that much money to pay.

So I gotta think of ways to make actual money. I’ve never had a job before. I used to clean my dad’s shoes after work and he’d give me a 20, a 50, sometimes an 80 (this is in Mexican pesos, a.k.a. a one-buck, a two and fifty, and 4 bucks, respectively).

A few months ago in December 2021 I tried to get a job at a computer/printer/phone repair shop but didn’t get a reply. I was too lazy to reply again and say something like, so you want me or not?

But now I’m like not that long from maybe getting my father into much more debt so I gGOTTA make money!!

Physical money, yes, not just philosophy or learning stuff or linux or programming or going out or helping people but getting someone else to give me money for something that I do.

So I though of places where I’d like to work at. I don’t want to work at places where their job is to steal other people’s data. No NONO NONO . morally incorrect, very. for now I don’t want to work at a crazy FAANGM company!.

But I’m getting ahead of myself. The reality is the only place I though of to actually work at is comma.ai . Yes, that small startup that is changing the world and I think has more than a million miles of possible training data to make autonomous cars.

So I got to their careers page and eventually found out that they require some kidn of programming challenge to enter their company. I had read about this on an HN post I submitted, it was one of George’s blogposts.

ah, shit I got caught off again procrastinating when trying to find my hn submission. here it is.

anyways, I should do this programming challenge and probably should ask for a maybe remote internship ?

But one step at a time I guess…

I should probably eat.

Hello, I am bored. Also, I’ve thought of kinda making my own daily blog entries so here is one!

Today, well, more like yesterday since it’s already midnight. I’m actually waiting for my other laptop to finish copying a disk partition to another disk. I’m using the one and only, legendary… dISk d3stroy3r !!! Yes, that’s right, I saw that in a Luke Smith Video! the thing is, I was setting up the archivebox software which is basically a self-hosted archive / wayback machine, pretty self-explanatory. I set it up with docker and after a while of restarting it for some weird reason the home directory of a new user I’ve created was being chmoded by docker or the software and idk really know what happened. Eventually, I figured out that for some stupid reason I had no disk space left on my home partition. But it only marked like 30 gigs used, meaning that for some weird reason I didn’t extend the partition ? So i got out my trusty red usb with ventoy on it (lets you boot multiple OSes easily) and hopped on to gparted. It’s literally just raw debian ( i think?, i’ve never tried it :v ) with gparted installed. it has an old school GUI like windows xp, has work spaces, you can move windows around. a pretty solid desktop environment. So, anyways, back to the story. I opened gparted and there it was, like 100GB of free, unpartitioned, unallocated space! so yeah, i just extended the home partition and no errors baby!

By this point. I shutdown the laptop, disconnect the trusty usb with oses and boot the computer, everything seems normal, although the error still appears telling me that there’s no disk space! Oh no, maybe the root partition?! So I just ran df -h to show available disk space on mounted file systems, and low and behold!, indeed the root partition is full! What!?, I only allocated 20GB to the root partition!?, who was the stupid guy that did that ? (me of course) and then proceeded to create the swap and boot partitions right next to it so that no free space is available. Yayyy!!? my self! So yeah, moving partitions around is more prone to errors. Plus, if you move any of the boot and/or root partition your system might not boot, not pretty. So, just to be safe I got a spare HDD and clone the root and home partition to it, because why not? After that I’ll probably just wipe the boot partitions from an archlinux iso in the trusty usb and move the partitions around hoping that I don’t have any errors so that I can extend the free space in the root partition! Might as well use the external HDD as the whole home partition! Why not? hmm, idk I’ll think about it.

Some other things I did during the day (december 07 2021) were walk with my dog, her name is Candy. Just walked around the neighbourhood, went to some benches/tables with grass and a lot of sun! and setup a tiny parasol (omg is this actually a word in english! I couldn’t believe that when duckduckgo showed the translation of sombrilla from spanish into parasol in english ?! wft, why don’t we Mexicans use this parasol word? maybe some old people do). Also, I was planning on reading some French(-speaking?) poetry and translating words i didn’t know with a small spanish-to-french and viceversa dictionary. In the end I only read like half of one page and got bored and walked with my dog again who was escaping.

Honestly, I though the disk destroyer MI (mission impossible): operation would be done by now. But it’s not!? 60GB copied baby! no idea if it will copy the whole partition with the unused space? ah, maybe, maybe not…

later in the day I started to use my laptop to research how to take screenshots of webpages and just sat there, contemplated my life appreciating the fact that puppeeteer ( i still don’t know if i got taht spelling right!) exists. Yay, so I could take screenshots using the chromium browser in headless mode! Nice. Now I just want a way to make my own http://archive.is or wayback machine! But without the shady tracking. I don’t remember where I heard but I think it has some serious web tracking and a ton-shit of cookies. I only like real cookies. smh. and i bake them with my sister and we make the dough from scratch and they’re delicious. and I like those cookies, I do not like these virtual, weird-ass cookies. I like tasting them irl.

wow, got a 781 word count! This guy knows how to speak/write/whatevss. anyways, back to the story. I was trying to figure out how to ‘save’ the webpage. You know, how when you’re in chrome/firefox and press ctrl+s and it saves an html and the images i think as well. yeah, that. well, it turns out there’s no easy way per se of doing that. after kinda pulling my hair out of my scalp I encountered the archivebox while searching through the aur for archive to see if there was any kind of self-hosted software that was like a little wayback machine! So it turns out it exists and I guess it kinda works! the web UI is okay, maybe a little bloated, it has like fuck'in 11 cookies, and most definitely not the kind you can eat! So yeah, now I can archive urls and store them on my computer and let others archive urls and save it to my computer, hope I don’t get sued for archiving something that other people aren’t happy about. aahhhh, this disk destroyer thing isn’t over yet. My plan was to just reinstall grub and the boot partition and that’s it man! just re-make the /etc/fstab so that the new uuids are recorded and that’s it! But no!, it was my great idea to re-extend the partition so now it’s copying everything! f**c it, i’m cancelling the operation and shrinking the partition as small as I can! holy shit! I only use like 2.16 GB in my home partition! no wonder docker was complaining! I shrunk the partition to 5 GB just to be safe and we should be re-installing and moving partitions round nd round in no time ! Nice! gparted took literally less than 1 minute!

now just gotta create the boot partition from the usb thingy!

turned out great. kinda. was a few minutes wondering why there were no kernels added to the grub config. Turns out kernels are installed in the boot partition! I deleted that partition! who would have known that? silly me, just had to pacman -S linux and remove the old linux-zen which was having trouble with docker.

done i guess. you should be able to see this site now. back in business baby.

Project Ideas

Posted on:	12/06/21 19:39:10
Last edited:	02/01/22 20:05:00

this file contains a simple list of project ideas which may include software projects with a small aim: providing something that isn’t currently available.

If the project is in progress, it’ll be listed just after it.

If you have any ideas for projects…

• short: short url service with simple GET/POST http requests and minimalist web UI.
• clipme: copy of http://0x0.st . simply receive get/post requests and make a file publicly available.
• archivemoi: web archiver, just like the web archive wayback machine. maybe using pupeteer (python library to use the chromium debugger thingy) to take high quality screenshots, make PDFs and archive the hole html thing.
• implement all of the above using something such as fastcgi to serve with simple web requests or something
• simple rss reader that parses rss/atom files and gives you a summary in html form or even ANSI!
• make simple, suckless, maybe in C, clipboard http POST pastebin. (examples: https://github.com/Willyfrog/pastas, http://0x0.st, http://ix.io)
• simple terminal ncurses app that can parse and generate vcard contact info!
• archivemoi-gh: GitHub archiver, generate token w/ private repo permissions

Hello, this is just a list of useful links of geohot’s hard-to-find (not that hard actually) blogs. He actually still blogs but much much less since he has a startup to take care of called comma.ai.

• Geohot’s current blog: geohot.github.io/blog/
• Jailbreak blog: from 2007 to 2009: iphonejtag.blogspot.com, archived.
  • lpahome.com

i should probably go study french or something, shit. My exam is in less than 12 hours. ignore this, wait, don’t ignore me.

adding the fzf plugin to vim

Posted on:	11/27/21 00:37:01
Last edited:	12/01/21 13:50:52

hey there! I don’t know why this came to me but I guess I’ve seen several internet videos in which linuxy users are using a nice, fancy prompt to search files. Turns out they’re using fzf! , a nice tool to easily search for files in the command line. To some degree I guess it is like a dmenu prompt but in a command line. So yeah, by default it acts like a find any file recursively in the current directory, yes, including hidden files; yet still acts like a standard unix command that can take input from stdin (standard input) and only show those choices and of course, prints to stdout the result.

So one can do something like

cat << EOF | fzf
one
two
three
four
john cena
EOF

and that will basically show you an interactive command line prompt which can let you make a choice. This is kind of similar to pedantic software’s choice tool by Sylvain Gauthier and Francois-Xavier Carton. Here’s a blog post from Sylvain in which he explains what his tool does and its uses. I guess it kinda differs to some degree but yeah.

Anyway, back to the fuzzy finder. So after seeing how not so useful this was, at least to me, I decided to make a quick internet search to see if I could use this in vim. And I could! As I’ve already said at the start of this post, I’ve seen several internet humans use vim as a file-finder. So I cloned a sample vim plugin which connects the fzf vim plugin which only gives core functions but doesn’t actually implement anything. So installing all these stuff gives me a pretty prompt like this:

and yeah that’s cool, isn’t it? If you’re interested in how to set it up I’ll put the steps below:

1. install fzf, can be found in the official Arch Linux repos and pretty much any other distro

2. install fzf core functions vim plugin; simply clone the official fzf repo to ~/.vim/pack/plugins/start/fzfcore to start the plugin on vim startup.

git clone "https://github.com/junegunn/fzf.git" ~/.vim/pack/plugins/start/fzfcore

note: this will only work if you have the vim pack functionality. It probably is if you keep vim up to date. I think this was released in vim 8.0

1. install fzf.vim as another vim plugin. Same as step 2.

git clone "https://github.com/junegunn/fzf.vim" ~/.vim/pack/plugins/start/fzf.vim

And that should do the trick. Now just readthedocs @ the fzf.vim docs readme and tldr;: use :Files to search within your home dir, hit enter and the file will be opened in vim. Also, it will show you a small preview (with syntax highlighting, if bat is installed.)

that’s it for this blog post. should probably sleep.

It’s quite simple. No, I didn’t create any of these config files but I guess sharing is caring, right?

The Myth of Technology: Computers for Cynics 0

a video by Ted Nelson:

https://m.youtube.com/watch?v=KdnGPQaICjk

I don’t remember how i stumbled upon this video. Here are some ideas I wrote down.

• junk not knowing who to blame.

hopes and dreams.

“I don’t understand technology” –> “I don’t get the crappy menus…”

yes, OF COURSE you can argue with tech !

MS windows

the wrapper is what we see!

determinism. nature is given.

“why can’t I x,y,z,…” –> “because computers don’t allow it!”

yes, so true! I think we should all break from our shells

• there are no objective criteria.
• like dog breeds, there are thousands of computer ideas and they can be endlessly combined
• many of them [ideas] have fanatical following
• then gives examples of several softwares and how they kind of came to be
  • utf-8, ascii, another weird character set that was like 7 bits for chars and 4 bits for numbers ?

Rant on "Writing"-ish tools

Posted on:	11/18/21 19:30:23
Last edited:	04/29/22 12:18:56

whoami ? well, honestly, no one to have the authority to say anything relevant regarding this issue. I am merely a teenager so please you have all the right to ignore this stuff; also, i don’t know why i just wrote this paragraph.

Well, let’s get to it. Thanks to my respect to myself of privacy and the right to actually have an annoying private life and talk to people, browse the internets without actually being spied on and be farmed on as a farm animal for personal data I have several ads coming up very often. Repeating themselves. A lot. Literally, a lot lot lotlotststs.

The ad that’s annoying me the most is Le Grammarly. You’ve probably heard of it if you’re a student, unfortunately. I don’t have any actual grudge against spell checkers or whatever but I think taking the things to a much farther level is bad. You shouldn’t be inferring or passive-aggressively suggesting grammar styles to students. They should write like they want, of course when turning in an assignment check your spelling and coherence of ideas or whatever; but that’s it! Literally it! I shouldn’t have a little shit software tell me that I’ve plagiarized something! If I have, I will definitely know myself. Okay, maybe if you forget but that’s it. Also, I think that these kinds of companies that most likely use a shit-load of data-sets to infer what should be written are wrong. Just like several machine learning algos have proven to have very biased datasets, this could prove a new era of having biased opinions, essays, and ideas in general. We do not have to put everything thru a pseudo-fancy software that tells you which ideas are right and wrong and/or (in) coherently written. That’s literally the job of your teacher. If you’re leaving it up to gruh-meourlee to tell you what to write you shouldn’t consider writing at all. It’s your writing! It’s yur ideas! Decide for yourself. fuck up for yourself and don’t.

yeah, that’s it. Maybe I’ll do one on the cheesy-like software if you know what I’m talking about. I’ll maybe rant about plagiarism and capitalised knowledge when studying. Not sure if I said that write. English is (not?) my first language. I was born in the U.S. but only lived there for 4 years ffs, so I guess I’ve absorbed a style of my own and I should note, most of the internet/media content I view / watch / listen to is in English, so yeah, there’s that. Whatever.

Working with git hooks.

Posted on:	11/14/21 21:50:43
Last edited:	11/14/21 21:52:47

edit: see end of post.

Hey there fellow read-capable human! I am here to tell you a story about git hooks. Well, first let’s talk a little bit about how remote repos work.

From the little knowledge I think I have, a git server can be run through ssh, you must create a git user which is in fact the user you login as when pushing your git object references. Most of the time, this will happen in a bare git repo. That is, a repo which only contains the contents of what you would normally expect the

.git

contents to be. So in fact there’s no working directory but only history changes with reference objects and stuff. But in fact this is probably wrong, as most people most likely use services such as github.com, gitlab.com, etcetera. And those websites can show you the files and in fact show you the ‘working directory’ of you repo, and the files themselves. So most git servers you interact with are probably not bare since the aforementioned services show you the files. So I chose to setup a git server on my home server , pretty straight forward. Setup some ssh keys to not be spammed or something. Then I had the amazing idea to migrate my blog over to my home server so I did it and migrated slowly to blogit. Actually, I started my own fork: github/trevcan/blogit. So anyways, back to the actual story.

My blog was doing okay until I started to try building server side. The problem was that the articles were being messed up in terms of last edited and last updated dates and I really didn’t know what to do. Until I stumbled upon the fact that having different locales can mess up programs such as the gnu’s coreutils program sort. So yeah, all I had to do was export LC_ALL=C to make it fix itself.

Then I wantd to find out how to automate this process. Since I could already push to my own git server, I was able to use git hooks. But after that I kind of got lost since the commands did execute but the index.html file was never properly generated. This is due to the fact that git proudly changes some environment variables because it wants to and barely documented them [0]. So I stumbled upon [1] and then found out all I had to do was add the unset function to that env variable since blogit uses git magic to figure out the last updated and last edited things and it though my repo was somehwere else when it wasn’t so yeah. I actually haven’t tested it and after I finish writing this blog post it will be the actual guinea pig to see if it actually works. You know, so I don’t get stuck in the ‘automating somehting for hours and not do any actual work’ thing. So I’m writing this post as kind of an obligatory thing since I barely have anything on the blog. I mean, I have like 20 articles but most of them barely say anything.

Anyways, I’m going to track this on git and commit and push I guess.

references

• 0: Missing git hooks docs
  • 1: git post update script does not work stackoverflow.com

guess what :( ?? it didn’t work. apparently it’s not pulling the latest changes I push for some weird reason and when I pull them as the git user in a shell it works perfectly fine and detects new changes. i removed some arguments i had in the git pull command so let’s see if that works.

you should watch it.

spoilers ahead if that ain’t obvious enough.

Hey there, I just watched the movie Un beso en el asfalto (2017) filmaffinity.com and it was pretty cool. Weirdly enough, I think that it was hilarious that it showed surprisingly different perspectives from all angles, even outside the context of the movie. Hell, it even showed a threatre reading the script, presenting it with props in front of an audience, and when they were recording it. It was kinda like Shutter island in the sense that the end is whatever your brain’s interpretation is. So yeah, maybe I’ll update this post idk.

log: ~ 6:24 P.M git status has one untracked file. only one. no changes on tracked files. will try to build /deploy the site without adding this new blog post.

test 1

$ make main a lot of text and shit git status now shows indeed more untracked files; the new blog post, the tags folder, the blog folder and the www folder

---

I am now opening the www/index.html file relative to the repo root. Yayyy!!! it works like a charm. CSS works, everything works. The latest article I published is “Derivatives Stuff Calculus” and is indeed correct. At the time of writing this, it is the only article that has been created,commited, and pushed to the github and home server repo. So yeah, it works.

small note: something i noticed is that sometimes the tags were kind of misplaced, sometimes the tag TBA * appears almost at the start, near ‘API’ and ‘C’ but now it seems to be in the 2nd line.* This is definitely not the case when viewing the version with the bad commit dates wrong sample

test 2

ok, so as we can see in test #1, it worked like a charm when not adding any new files, having a clean build dir and one new blog post (untracked file).

Now, I wonder something, if I did not commit any changes, the last commit I made is the same as the last one in the github repo, which means that they built off of the same commited files. How can having untracked files and a clean build dir affect this ?? who knows…

Now what i will do is execute a clean

$ make clean

now i will attempt building the site again and comparing results. Keep in mind that I still have the untracked file.

$ make main

ok, great. Same thing, results are literally the same. Honestly I expected this since the ‘main’ target in the makefile has as a first dependency the clean thingy.

note: maybe it has to do something with the .PHONY thingy * in makefiles. that you’re supposed to use it your targets* * aren’t actually files ??? *

okay. now to experiment # 3

test 3

okay, so my plan for test 3 is the following. make clean, then start tracking the new blog post i just made, commit only that change, make clean again, and try to build. Between each of these operations, I will build and ‘deploy’ the site locally to see if it changes in any particular stage.

$ make clean
$ make main

I did it and then another main just to be safe and sure enough, it is working persistently as expected.

$ git add articles/why-blogit.md
$ make main

Ok, still the same, since I haven’t made a commit with the new article, the article should not appear on the index, which is good and works as expected. The other articles still appear in the right order. now let’s commit changes!

$ git commit -m 'add blogit issue article'
$ make main

and sure enough, works like a charm! the new blog post appears at the top and the next one is indeed the last one I committed, which makes lots of sense. So, nothing wrong as of now…. now let’s do exp 4

test 4

so now i want to try to make a clean, and then a main.

$ make clean
$ make main

ok, great. It still works like a charm! literally got the same exact content. now on to test 5

test 5

I honestly do not know what to try now. I think in this one I’ll checkout to the last commit the github repo has (25f4b89, 5 h ago) and try building it.

first of all, I’ll try to clean up.

$ make clean
$ git checkout 25f4b89 
$ make main

ok, so (un)fortunately I still have not found the bug! It still builds as if it were very normal! In fact, it indeed builds correctly, but for some reason it did not when I pushed it to github pages ??

now i really don’t know wut to do. now i will checkout to master

$ git checkout master

ok

test 6

now i will attempt to push my latest commit to the github repo and to my home server, I will try to see if behaviours change.

$ make clean
$ git push

ok, the github push built in like 25 seconds. so yeah, that’s great i guess. Now the moment of truth…. ah shitt…. for some weird reason it keeps not using the correct commit date. Weirdly enough, all the articles show the same DATE but not the same time. the 404.md simply says that it was allegedly last edited today, 11/10/21 @ 13:19:18. now my new blog post which appears at the bottom literally the third one from bottom to top!, it says that iwas last edited also today 11/10/21 @ 18:41:11 which is correct! now I do not know what the issue is..!!

okay, now let’s try pushing to the home server and seeing if we have the same results.

$ make clean
$ git push home-site

okay, I’ve pushed the master branch to the master branch at the home server, let’s try this. okay so I’ve built it from my home server. But now it shows somehwat wrong results but still different than github. I reckon this has something to do with dates. This is getting interesting or idk. Now the first article at the top is ‘How do i fix this blogit’ which is, indeed, the last article I committed. But the next one is 404, which is definitely not what I’ve committed recently. next is about:trevcan, haven’t made any recent updates, and so on. the second most recent article is right below the middle, the sixth one from bottom to top.

How do I fix this blogit?

Posted on:	11/10/21 18:41:11
Last edited:	11/10/21 18:41:11

hey there, I hope you are having a nice day. Today was a much more intersting day than the rest of the week, I got to actually deploy my blog mirror and it literally looks exactly like on github, exect that mime types are not auto-completed like in github, e.g. i can type something like

http://trevcan.github.io/index

and it will be the same as

http://trevcan.github.io/index.html

and so on. I guess there’s some plugin in nginx that I can use or something. Should also add https or something, although since I’m not hosting any arbitrary code, it is simply rendering html and css (no js folks!) it shouldn’t be a problem, right?

---

Well, onto another random thing. There’s a problem with blogit (mirror . See, the issue is that sometimes I deploy it and it works perfectly. The most recent article pops up at the top of the index html file but sometimes, more like almost every time it stops working out of nowhere! Github and my computer and my home server all react the same way as long as they were on the same commit/ working directory etc…. When this happens, every article gets the same edit date which is nuts! And then for some weird reason the 404 article pops up right at the top! look!

So yeah I’m not sure how I’ll tackle this problem. I was doing some light testing and I think when one of the build directories existen the commit date/ last edited date worked correctly and most recent articles were always at the top. I guess I’ll look into that.

Also, as you might have noticed, I now have a static html thingy showing some git repos. the server works and everything and I’m using duckdns.org to serve my dynamic ip address and use their free dns subdomain services and it works well enough and you can have up to 5 subdomains.

so yeah, that’s it. I'llprobably solve this problem right now maybe??

Another year, another FRC Season. I’m currently in the Tecbot 3158 First Robotics Competition, a great way in which students of all STEM fields can show their abilities through teamwork.

Right now, I’m in the engineering part. My job, for now, is to gather scouting data for our team to analyze with maybe some ML models or just to make simple statistics.

setup

Thankfully, TBA (the blue alliance) has a public read-access (and write, i believe) API, it’s JSON and it lets you access almost everything. You just have to sign in with google and get an API key. Now use any HTTP-GET friendly request to retrieve data. Just remember to assign the HTTP header X-TBA-Auth-Key to the API key you receive.

Hello there,

I’ve been trying out several bloggin systems but none of them seem to work as I expect them. Well, to be frank, the only blogging systems I’ve been trying are only Jekyll/Github based. The only thing I want is a nice hacker-like aesthethic because why not and minimalist software that doesn’t have a ton shit of folders like Jekyll, I just don’t get why I can’t add posts anywhere other than in _posts/!!.

Also, this is a check to see if this post actually gets built because only the sample posts have appeared so far !!. Edit: You know what?, why not start doing it right fucking know lol. I guess I’ll create a test repo where I can idk do shit and test blogit.

Hello there, I’m a human! I’m into programming, computers, and of course, the beloved linux (I use arch btw). I like learning about new things, and enjoy riding bikes, reading books such as 1984 (George Orwell), talking to people, and breathing.

And yeah, I’ve decided to start writing / blogging so yeah this is me attempting to set up a minimalist blogging system with blogit I guess and a tad of github actions automation with gh pages.

contact info here

Software used:

• webserver - lighttpd, pronounced lightly.
• markdown or discount > A Markdown implementation written in C.
  • it’s in the arch repos as the discount package but installs a program called markdown among other things.
  • https://www.pell.portland.or.us/~orc/Code/discount/
  • by David Parsons
• Web page styling (CSS) by tocttou’s hacker-blog
  • with slight modifications from myself.
• my fork of blogit
