XLD, Mp3tag and VLC

I am a little bit tired of the Music app. Recently, I lost all my songs due to moving the library to an external drive. I don’t say it was not my fault. It might be that I haven’t applied enough magic to the whole process. Anyway, I have ended up with this. I have […]

LEGO EV3 – Tank Bot and evil Python error :)

So, eventually, we have built Tank Bot according to the manual. Once everything was set up inside VS Code it turned out our Tank Bot doesn’t work as expected.

(Docker based installation of Bitwarden)

Self hosted Bitwarden on Debian 12

I need a password manager – I simply have too many passwords. For a very long time my weapon of choice was Locko. However, due to it’s lack of sharing passwords locally (e.g. via some personal cloud) I have decided to look for something else. Bitwarden seemed like a good idea. Open Sourced, allows self […]

I don’t know how is it about you, but in my case, I have already faced the total lag of the system due to having / consumed 100% by Docker. At the time of writing, I have made two things to save my Macintosh HD. First, push yourcom.docker.docker out of your system HDD. Second. Make […]


Building OpenCoarrays on macOS
– everything from the sources – gcc-13.2.0
