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 :)

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....

In the last days I set up a node of a decentralized VPN using the Mysterium network. This was mainly to get profits from the Internet bandwidth I don’t use and to help provide freedom of speech for those who need it. What is Mysterium? Mysterium is ‘a global, distributed network powered by everyday people. Network participants are incentivised to share their resources in a supply and demand marketplace, helping others gain access to the open internet’....

I recently watched a NetworkChuck’s video where he explained how to protect your linux server (Dedicated to Ubuntu, but I plan on covering more than just that distro), so I thought that I could do some sort of writeup of the video as well as extend the info that is shown in it. Securing your linux server is an essential aspect to keep it running and to avoid any infiltrations in your network that could lead to data breaches, which nobody wants....

What’s this Endlessh is a piece of software that sets up a ssh honeypot for all the random people that may try to attack you by trying common username and password combinations to see if they can get access. In return, this program slows their access down hugely, and in a way someone with a script to do the attack won’t notice (most people doing these kind of attacks will be using scripts)....

The first post It is always difficult to start something new: new habits, a new job or maybe a new relationship. But I hope that this blog I’m deciding to start writing on from today once becomes a reference page for someone’s projects, inspiration or entertainment. I hope this becomes useful for someone that just wants to get answers that happen to be here, quickly. I don’t have many things to say yet, I don’t have a clear path to follow nor I want one....
