Hago públicos mis “dotfiles” Puede que no te sorprenda, en el fondo ya llevo tiempo teniéndolos públicos, pero hace un par de meses cambié mi forma de lidiar con ellos y estoy contento con cómo están quedando, así que ahora estarán públicos por si quieres inspirarte (guiño guiño). Qué vienen siendo los dotfiles? Pregunta sin miedo! En resumidas cuentas, son los archivos de configuración que se usan en Linux1. Se les llama así porque van precedidos por un punto, que se interpreta como que son archivos ocultos. Es cómodo, porque un usuario casual del sistema no los verá y no le molestan, pero son fáciles de modificar y están a mano para quien sí quiera usarlos. ...

Casi que no comento nada sobre qué son y esas cosas que se suelen poner de relleno al principio de las publicaciones para retener más a la gente, a estas alturas no creo que haya mucha gente que no haya oído “IA” o “red neuronal” más de 20 veces. No tengo anuncios así que no gano nada si me lees durante más tiempo y cuanto menos te lleve, más tiempo tienes para otras cosas. ...

The idea This video from a really nice channel I follow popped up on my YouTube feed, it was a neat idea, and I thought showing the max speed as well as the current speed would be really useful. The first thing I needed was to get the current location, but I know it’s relatively easy to do once you have a GPS module. ...

Repo Car Report Car report is an app I found around 2 years ago in F-droid. It is a simple app that helps you track your car expenses. It had an old UI but it had many features and it was really easy to use. I was really happy with the app, so I decided to investigate the app and found out that it was unmaintained since 2019 (officially since 2021). ...

This post is a collection of my preferences on some aspects. It will be updated as I explore more and have some more opinions that I want to share. Feel free to tell me why you don’t agree with me in the comments. Dates and times Dates and times are really well defined in the ISO 8601 standard. Dates are represented as YYYY-MM-DD and times as HH:MM:SS. For full timestamps, the date and time are separated by a T and the timezone is appended at the end. For example, the current time in ISO 8601 format is 2024-07-10T15:04:06+02:00. ...

I recently had to install some software in my computer that I knew would mess with system libraries and give me some trouble in the future, so it occurred to me that using a VM and connecting to it through the VSCode SSH Tunnel extension to write the code I needed could be a great alternative to installing it directly and it wouldn’t break anythin in my OS. Introduction My current setup This is a bit of a disclaimer of sorts. ...

This post will cover my attempt of building a completely open way to read the OBD2 messages sent through the CAN bus of a car, and communicating with the ECU (Electronic Control Unit), basically “the brain” of the car. More will be coming :) Update on 2024-07-10 I’ve been working in this project since before writing this post, and there’s more info to share than I initially thought. I think a better way to share this is to write a series of posts, showing my progress and what I’ve learned so far. ...

This post covers some settings I have discovered about SQLite these days that help it perform better without losing consistency. The official reference and the sources of my discoveries will be listed in the References section below. This will be a short one, mainly to help future me, but also for anyone planning to use SQLite in production (including me). Configuring SQLite A few days ago I thought SQLite didn’t need any configuration but oh boy was I wrong. ...

I recently bought this laptop and I wanted to test it to see if it fitted me, so I thought I would publish the results in case it helps anyone with their decisions. These results won’t be scientific, but they can serve as a guideline to estimate the performance of this and similar processors taking also into account other measurements from more scientific sources such as CPUMark or Geekbench. They won’t be perfect either, no test ultimately is, but I think they’re worth taking into account. ...

Creating a NFS share is quite easy, and it’s a fast way to share files between Linux hosts, and apparently even with recent Windows machines (untested). Samba (SMB) is the native way to do it in Windows, but comes with some more overhead which reduces its file transfer speeds (untested). NFS Required packages The required packages are the following: # Arch Linux sudo pacman -S nfs-utils # Debian and derivatives (Ubuntu, etc.) sudo apt install nfs-kernel-server Share creation After choosing the folder you want to share, you’ll need to define the shared folders inside the /etc/exports file (created after the package installation). ...
