Al fin ya me acomodé la página pa' los dibujos

Así es, ya quedó acomodado el sub-dominio art.luevano.xyz pos pal arte veda. Entonces pues ando feliz por eso.

Este pedo fue gracias a que me reescribí la forma en la que pyssg maneja los templates, ahora uso el sistema de jinja en vez del cochinero que hacía antes.

Y pues nada más eso, aquí está el primer post y por supuesto acá está el link del RSS https://art.luevano.xyz/rss.xml.

Así nomás está quedando el página

Estuve acomodando un poco más el sItIo, al fin agregué la “sección” de contact y de donate por si hay algún loco que quiere tirar varo.

También me puse a acomodar un servidor de XMPP el cual, en pocas palabras, es un protocolo de mensajería instantánea (y más) descentralizado, por lo cual cada quien puede hacer una cuenta en el servidor que quiera y conectarse con cuentas creadas en otro servidor… exacto, como con los correos electrónicos. Y esto está perro porque si tú tienes tu propio server, así como con uno de correo electrónico, puedes controlar qué características tiene, quiénes pueden hacer cuenta, si hay end-to-end encryption (o mínimo end-to-server), entre un montón de otras cosas.

Ahorita este server es SUMISO (compliant en español, jeje) para jalar con la app conversations y con la red social movim, pero realmente funcionaría con casi cualquier cliente de XMPP, amenos que ese cliente implemente algo que no tiene mi server. Y también acomodé un server de Matrix que es muy similar pero es bajo otro protocolo y se siente más como un discord/slack (al menos en el element), muy chingón también.

Si bien aún quedan cosas por hacer sobre estos dos servers que me acomodé (además de hacerles unas entradas para documentar cómo lo hice), quiero moverme a otra cosa que sería acomodar una sección de dibujos, lo cual en teoría es bien sencillo, pero como quiero poder automatizar la publicación de estos, quiero modificar un poco el pyssg para que jale chido para este pex.

Ya por último también quiero moverle un poco al CSS, porque lo dejé en un estado muy culerón y quiero meterle/ajustar unas cosas para que quede más limpio y medianamente bonito… dentro de lo que cabe porque evidentemente me vale verga si se ve como una página del 2000.

Actualización: Ya tumbé el servidor de XMPP porque consumía bastantes recursos y no lo usaba tanto, si en un futuro consigo un mejor servidor podría volver a hostearlo.

Así es raza, el blog ya tiene timestamps

Pues eso, esta entrada es sólo para tirar update sobre mi primer post. Ya modifiqué el ssg lo suficiente como para que maneje los timestamps, y ya estoy más familiarizado con este script entonces ya lo podré extender más, pero por ahora las entradas ya tienen su fecha de creación (y modificación en dado caso) al final y en el índice ya están organizados por fecha, que por ahora está algo simple pero está sencillo de extender.

Ya lo único que queda es cambiar un poco el formato del blog (y de la página en general), porque en un momento de desesperación puse todo el texto en justificado y pues no se ve chido siempre, entonces queda corregir eso. Y aunque me tomó más tiempo del que quisiera, así nomás quedó, diría un cierto personaje.

El ssg modificado está en mis dotfiles (o directamente aquí).

Por último, también quité las extensiones .html de las URLs, porque se veía bien pitero, pero igual los links con .html al final redirigen a su link sin .html, así que no hay rollo alguno.

I’m making this post just to figure out how ssg5 and lowdown are supposed to work (and eventually also rssg).

At the moment, I’m not satisfied because there’s no automatic date insertion into the 1) html file, 2) the blog post itself and 3) the listing system in the blog homepage (and there’s also the problem with the ordering of the entries…). And all of this just because I didn’t want to use Luke’s solution (don’t really like that much how he handles the scripts… but they just work).

   I'm using a new blogging system
 
   So, I was tired of working with ssg (and then sbg which was a modified version of ssg that I “wrote”), for one general reason: not being able to extend it as I would like; and not just dumb little stuff, I wanted to be able to have more control, to add tags (which another tool that I found does: blogit), and even more in a future.
 The solution? Write a new program “from scratch” in pYtHoN. Yes it is bloated, yes it is in its early stages, but it works just as I want it to work, and I’m pretty happy so far with the results and have with even more ideas in mind to “optimize” and generally clean my wOrKfLoW to post new blog entries. I even thought of using it for posting into a “feed” like gallery for drawings or pictures in general.
 I called it pyssg, because it sounds nice and it wasn’t taken in the PyPi. It is just a terminal program that reads either a configuration file or the options passed as flags when calling the program.
 It still uses Markdown files because I find them very easy to work with. And instead of just having a “header” and a “footer” applied to each parsed entry, you will have templates (generated with the program) for each piece that I thought made sense (idea taken from blogit): the common header and footer, the common header and footer for each entry and, header, footer and list elements for articles and tags. When parsing the Markdown file these templates are applied and stitched together to make a single HTML file. Also generates an RSS feed and the sitemap.xml file, which is nice.
-It might sound convoluted, but it works pretty well, with of course room to improve; I’m open to suggestions, issue reporting or direct contributions here. BTW, it only works on Linux for now (and don’t think on making it work on windows, but feel free to do PR for the compatibility).

 That’s it for now, the new RSS feed is available here: https://blog.luevano.xyz/rss.xml.

   My setup for a password manager and MFA authenticator
 
   Disclaimer: I won’t go into many technical details here of how to install/configure/use the software, this is just supposed to be a short description on my setup.
-It’s been a while since I started using a password manager at all, and I’m happy that I started with KeePassXC (open source, multiplatform password manager that it’s completely offline) as a direct recommendation from lm; before this I was using the same password for everything (like a lot of people), which is a well know privacy issue as noted in detail by Leo (I don’t personally recommed LastPass as Leo does). Note that you will still need a master password to lock/unlock your password database (you can additionally use a hardware key and a key file).

Note that you will still need a master password to lock/unlock your password database (you can additionally use a hardware key and a key file).
 Anyways, setting up keepass is pretty simple, as there is a client for almost any device; note that keepass is basically just the format and the base for all of the clients, as its common with pretty much any open source software. In my case I’m using KeePassXC in my computer and KeePassDX in my phone (Android). The only concern is keeping everything in sync because keepass doesn’t have any automatic method of synchronizing between devices because of security reasons (as far as I know), meaning that you have to manage that yourself.
 Usually you can use something like G**gl* drive, dropbox, mega, nextcloud, or any other cloud solution that you like to sync your keepass database between devices; I personally prefer to use Syncthing as it’s open source, it’s really easy to setup and has worked wonders for me since I started using it, also it keeps versions of your files that can serve as backups in any scenario where the database gets corrupted or something.
 Finally, when I went through the issue with the micro SD and the adoptable storage bullshit (you can find the rant here, in spanish) I had to also migrate from G**gl* authenticator (gauth) to something else for the simple reason that gauth doesn’t even let you do backups, nor it’s synched with your account… nothing, it is just standalone and if you ever lose your phone you’re fucked; so I decided to go with Aegis authenticator, as it is open source, you have control over all your secret keys, you can do backups directly to the filesystem, you can secure your database with an extra password, etc., etc.. In general aegis is the superior MFA authenticator (at least compared with gauth) and everything that’s compatible with gauth is compatible with aegis as the format is a standard (as a matter of fact, keepass also has this MFA feature which is called TOPT and is also compatible, but I prefer to have things separate). I also use syncthing to keep a backup of my aegis database.

   Rewrote pyssg again
 
-  I’ve been wanting to change the way pyssg reads config files and generates HTML files so that it is more flexible and I don’t need to have 2 separate build commands and configs (for blog and art), and also to handle other types of “sites”; because pyssg was built with blogging in mind, so it was a bit limited to how it could be used. So I had to kind of rewrite pyssg, and with the latest version I can now generate the whole site and use the same templates for everything, quite neat for my use case.

 Anyways, so I bought a new domain for all pyssg related stuff, mostly because I wanted somewhere to test live builds while developing, it is of course pyssg.xyz; as of now it is the same template, CSS and scripts that I use here, probably will change in the future. I’ll be testing new features and anything pyssg related stuff.
 I should start pointing all links to pyssg to the actual site instead of the github repository (or my git repository), but I haven’t decided how to handle everything.

   I’ve been wanting to do this entry, but had no time to do it since I also have to set up the VPN service as well to make sure what I’m writing makes sense, today is the day.

-Create PKI from scratch¶
+Create PKI from scratch¶
 PKI stands for Public Key Infrastructure and basically it’s required for certificates, private keys and more. This is supposed to work between two servers and one client: a server in charge of creating, signing and verifying the certificates, a server with the OpenVPN service running and the client making the request.
 This is supposed to work something like: 1) a client wants to use the VPN service, so it creates a requests and sends it to the signing server, 2) this server checks the requests and signs the request, returning the certificates to both the VPN service and the client and 3) the client can now connect to the VPN service using the signed certificate which the OpenVPN server knows about. In a nutshell, I’m no expert.
 … but, to be honest, all of this is a hassle and (in my case) I want something simple to use and manage. So I’m gonna do all on one server and then just give away the configuration file for the clients, effectively generating files that anyone can run and will work, meaning that you need to be careful who you give this files (it also comes with a revoking mechanism, so no worries).

Create a website with Nginx and Certbot

These are general notes on how to setup a Nginx web server plus Certbot for SSL certificates, initially learned from Luke’s video and after some use and research I added more stuff to the mix. And, actually at the time of writing this entry, I’m configuring the web server again on a new VPS instance, so this is going to be fresh.

As a side note, (((i use arch btw))) so everything here es aimed at an Arch Linux distro, and I’m doing everything on a VPS. Also note that most if not all commands here are executed with root privileges.

 The game was originally developed with Godot 4.0 alpha 8, but it didn’t support HTML5 (webassembly) export… so I backported to Godot 3.5 rc1.
 Not going to specify all the details, only the needed parts and what could be confusing, as the source code is available and can be inspected; also this assumes minimal knowledge of Godot in general. Usually when I mention that a set/change of something it usually it’s a property and it can be found under the Inspector on the relevant node, unless stated otherwise; also, all scripts attached have the same name as the scenes, but in snake_case (scenes/nodes in PascalCase).
 One thing to note, is that I started writing this when I finished the game, so it’s hard to go part by part, and it will be hard to test individual parts when going through this as everything is depending on each other. For the next devlog, I’ll do it as I go and it will include all the changes to the nodes/scripts as I was finding them, probably better idea and easier to follow.

+Directory structure¶
 I’m basically going with what I wrote on Godot project structure recently, and probably with minor changes depending on the situation.
-Config¶
-Default import settings¶

+Default import settings¶
 Since this is just pixel art, the importing settings for textures needs to be adjusted so the sprites don’t look blurry. Go to Project -> Project settings… -> Import defaults and on the drop down select Texture, untick everything and make sure Compress/Mode is set to Lossless.
 
-
+
 Project settings - Import defaults - Texture settings
 
-General settings¶
+General settings¶
 It’s also a good idea to setup some config variables project-wide. To do so, go to Project -> Project settings… -> General, select Application/config and add a new property (there is a text box at the top of the project settings window) for game scale: application/config/game_scale for the type use float and then click on add; configure the new property to 3.0; On the same window, also add application/config/version as a string, and make it 1.0.0 (or whatever number you want).

 Project settings - General - Game scale and version properties
 
-For my personal preferences, also disable some of the GDScript debug warnings that are annoying, this is done at Project -> Project settings… -> General, select Debug/GDScript and toggle off “Unused arguments”, “Unused signal” and “Return value discarded”, and any other that might come up too often and don’t want to see.

-Keybindings¶
-I only used 3 actions (keybindings): jump, restart and toggle_debug (optional). To add custom keybindings (so that the Input.something() API can be used), go to Project -> Project settings… -> Input Map and on the text box write “jump” and click add, then it will be added to the list and it’s just a matter of clicking the + sign to add a “Physical key”, press any key you want to be used to jump and click ok. Do the same for the rest of the actions.

 For the assets I found out about a pack that contains just what I need: flappy-bird-assets by MegaCrash; I just did some minor modifications on the naming of the files. For the font I used Silver, and for the sound the resources from FlappyBird-N64 (which seems to be taken from 101soundboards.com which the orignal copyright holder is .Gears anyways).
-Importing¶
-Create the necessary directories to hold the respective assets and it’s just a matter of dragging and dropping, I used directories: res://entities/actors/player/sprites/, res://fonts/, res://levels/world/background/sprites/, res://levels/world/ground/sprites/, res://levels/world/pipe/sprites/, res://sfx/. For the player sprites, the “FileSystem” window looks like this (entities/actor directories are really not necessary):

-Scenes¶
+Scenes¶
 Now it’s time to actually create the game, by creating the basic scenes that will make up the game. The hardest part and the most confusing is going to be the TileMaps, so that goes first.
-TileMaps¶
-I’m using a scene called “WorldTiles” with a Node2D node as root called the same. With 2 different TileMap nodes as children named “GroundTileMap” and “PipeTileMap” (these are their own scene); yes 2 different TileMaps because we need 2 different physics colliders (In Godot 4.0 you can have a single TileMap with different physics colliders in it). Each node has its own script. It should look something like this:

-We need to do this because for some reason we can’t change the snap options before selecting a tile. After selecting a random tile, set up the Snap Options/Step (in the Inspector) and set it to 16x16 (or if using a different tile set, to it’s tile size):

 The ordering is important only for the “underground tile”, which is the filler ground, it should be at the end (index 3); if this is not the case, repeat the process (it’s possible to rearrange them but it’s hard to explain as it’s pretty weird).
-At this point the tilemap doesn’t have any physics and the cell size is wrong. Select the “GroundTileMap”, set the TileMap/Cell/Size to 16x16, the TileMap/Collision/Layer set to bit 2 only (ground layer) and disable any TileMap/Collision/Mask bits. Should look something like this:

-Now it’s just a matter of repeating the same for the pipes (“PipeTileMap”), only difference is that when selecting the tiles you need to select 2 tiles, as the pipe is 2 tiles wide, or just set the Snap Options/Step to 32x16, for example, just keep the cell size to 16x16.
-Default ground tiles¶
-I added few default ground tiles to the scene, just for testing purposes but I left them there. These could be place programatically, but I was too lazy to change things. On the “WorldTiles” scene, while selecting the “GroundTileMap”, you can select the tiles you want to paint with, and left click in the grid to paint with the selected tile. Need to place tiles from (-8, 7) to (10, 7) as well as the tile below with the filler ground (the tile position/coordinates show at the bottom left, refer to the image below):

Not sure if it’s a good practice to have the audio here, since I did that at the end, pretty lazy. Then, attach a script to the “Player” node and then it should look like this:

 I’m going to keep this scripting part to the most basic code blocks, as it’s too much code, for a complete view you can head to the source code.

I used [Chocolatey][https://chocolatey.org/] to install imagemagick, then to convert the icon itself used: magick convert icon.png -define icon:auto-resize=256,128,64,48,32,16 icon.ico as detailed in Godot‘s Changing application icon for Windows.

 To move other snake parts by following the snake head the only solution I found was to use the Path2D and PathFollow2D nodes. Path2D basically just handles the curve/path that PathFollow2D will use to move its child node; and I say “child node” in singular… as PathFollow2D can only handle one damn child, all the other ones will have weird transformations and/or rotations. So, the next thing to do is to setup a way to compute (and draw so we can validate) the snake’s path/curve.

Fix on body segments following head¶

After a while of testing and developing, I noticed that sometimes the head “detaches” from the body when a lot of rotations happen (moving the snake left or right), because of how imprecise the Curve2D is. To do this I just send a signal (snake_rotated) whenever the snake rotates and make a small correction (in generic_segment.gd):
```
func _on_snake_rotated() -> void:
     offset -= 0.75 * Global.SNAKE_SPEED * pow(get_physics_process_delta_time(), 2)

This is completely random, I tweaked it manually after a lot of iterations.

The food¶

For now I just decided to setup a simple system to see everything works fine. The idea is to make some kind of generic food node/scene and a “food manager” to spawn them, for now in totally random locations. For this I added the following signals: food_placing_new_food(type), food_placed_new_food(type) and food_eaten(type).

First thing is creating the Food.tscn which is just an Area2D with its necessary children with an attached script called food.gd. The script is really simple:

I’ve been wanting to get into gamedev for a while now, but it’s always a pain to stay consistent. I just recently started to get into it again, and this time I’m trying to actually do stuff.

So, the plan is to blog about my progress and clone some simple games just to get started. I’m thinking on sticking with Godot just because I like that it’s open source, it’s getting better and better overtime (big rewrite happening right now) and I already like how the engine works. ~~Specifically I’ll start using Godot 4 even though it’s not done yet, to get used to the new features, specifically pumped for GDScript 2.0.~~ Actually… (for the small clones/ripoffs) I’ll need to use Godot 3.X (probably 3.5), as Godot 4 doesn’t have support to export to webassembly (HTML5) yet, and I want that to publish to itch.io and my website. I’ll continue to use Godot 4 for bigger projects, as they will take longer and I hope that by the time I need to publish, there’s no issues to export.

For a moment I almost started a new subdomain just for gamedev stuff, but decided to just use a different directory for subtleness; this directory and use of tags should be enough. I’ll be posting the entry about the first rip-off I’m developing (FlappyBird L O L) shortly.

So, the next thing to do is to setup a way to compute (and draw so we can validate) the snake’s path/curve.

Fix on body segments following head¶

After a while of testing and developing, I noticed that sometimes the head “detaches” from the body when a lot of rotations happen (moving the snake left or right), because of how imprecise the Curve2D is. To do this I just send a signal (snake_rotated) whenever the snake rotates and make a small correction (in generic_segment.gd):

func _on_snake_rotated() -> void: offset -= 0.75 * Global.SNAKE_SPEED * pow(get_physics_process_delta_time(), 2)

This is completely random, I tweaked it manually after a lot of iterations.

The food¶

For now I just decided to setup a simple system to see everything works fine. The idea is to make some kind of generic food node/scene and a “food manager” to spawn them, for now in totally random locations. For this I added the following signals: food_placing_new_food(type), food_placed_new_food(type) and food_eaten(type).

First thing is creating the Food.tscn which is just an Area2D with its necessary children with an attached script called food.gd. The script is really simple:

Stats clas and loading/saving data¶

I got the idea of saving the current stats (points, max body segments, etc.) in a separate Stats class for easier load/save data.

One thing to note, is that I started writing this when I finished the game, so it’s hard to go part by part, and it will be hard to test individual parts when going through this as everything is depending on each other.

Note that you will still need a master password to lock/unlock your password database (you can additionally use a hardware key and a key file).

Anyways, setting up keepass is pretty simple, as there is a client for almost any device; note that keepass is basically just the format and the base for all of the clients, as its common with pretty much any open source software. In my case I’m using KeePassXC in my computer and KeePassDX in my phone (Android). The only concern is keeping everything in sync because keepass doesn’t have any automatic method of synchronizing between devices because of security reasons (as far as I know), meaning that you have to manage that yourself.

Usually you can use something like G**gl* drive, dropbox, mega, nextcloud, or any other cloud solution that you like to sync your keepass database between devices; I personally prefer to use Syncthing as it’s open source, it’s really easy to setup and has worked wonders for me since I started using it, also it keeps versions of your files that can serve as backups in any scenario where the database gets corrupted or something.

Finally, when I went through the issue with the micro SD and the adoptable storage bullshit (you can find the rant here, in spanish) I had to also migrate from G**gl* authenticator (gauth) to something else for the simple reason that gauth doesn’t even let you do backups, nor it’s synched with your account… nothing, it is just standalone and if you ever lose your phone you’re fucked; so I decided to go with Aegis authenticator, as it is open source, you have control over all your secret keys, you can do backups directly to the filesystem, you can secure your database with an extra password, etc., etc..

Depending on what port you want to run the VPN on, the default 1194, or as a fallback on 443 (click here for more). I will do mine on port 1194 but it’s just a matter of changing 2 lines of configuration and one Ufw rule.

Create PKI from scratch¶

Create PKI from scratch¶

PKI stands for Public Key Infrastructure and basically it’s required for certificates, private keys and more. This is supposed to work between two servers and one client: a server in charge of creating, signing and verifying the certificates, a server with the OpenVPN service running and the client making the request.

This is supposed to work something like: 1) a client wants to use the VPN service, so it creates a requests and sends it to the signing server, 2) this server checks the requests and signs the request, returning the certificates to both the VPN service and the client and 3) the client can now connect to the VPN service using the signed certificate which the OpenVPN server knows about. In a nutshell, I’m no expert.

… but, to be honest, all of this is a hassle and (in my case) I want something simple to use and manage. So I’m gonna do all on one server and then just give away the configuration file for the clients, effectively generating files that anyone can run and will work, meaning that you need to be careful who you give this files (it also comes with a revoking mechanism, so no worries).

The real way of doing this would be to run similar steps as the ones with easy-rsa locally, send them to the server, sign them, and retrieve them. Nah, we’ll just create all configuration files on the server as I was mentioning earlier.

This entry is mostly so I can record all the notes required while I’m in the process of installing/configuring the mail server on a new VPS of mine; ~~also I’m going to be writing a script that does everything in one go (for Arch Linux), that will be hosted here.~~ I haven’t had time to do the script so nevermind this, if I ever do it I’ll make a new entry regarding it.

This configuration works for local users (users that appear in /etc/passwd), and does not use any type of SQL database. And note that most if not all commands executed here are run with root privileges, unless stated otherwise.

Prerequisites¶

Basically the same as with the website with Nginx and Certbot, with the extras:

You will need a CNAME for “mail” and (optionally) “www.mail”, or whatever you want to call the sub-domains (although the RFC 2181 states that it NEEDS to be an A record, fuck the police).

An SSL certificate. You can use the SSL certificate obtained following my last post using certbot (just create a mail.conf and run certbot --nginx again).
