Year-end donations round, 2024 edition
Just in time before the year ends, I’ve gone ahead with my round of personal donations for 2024. I highly encourage you to do something similar and support the free and open source software and organizations that make a difference to you.
This year, my personal list consisted of:
Signal as every year, because I use it daily.
Calibre eBook Management, which my wife uses a lot.
The Gnome Project, which is my desktop environment these days.
LibreOffice because I use it very frequently and I think it’s a critical piece of software for the desktop.
Pi-Hole because I have one set up in my home network...
Casting video files from Linux to AppleTV
A couple of weeks ago I received an AppleTV 4K as an early Christmas present. It’s a really nice device and it immediately replaced my Chromecast Ultra as the way to watch streaming content on my 15-year-old non-smart TV. Of course, the kids love it too!
Before I disconnected my Chromecast Ultra from the TV to put it back into its box, there was a small matter I needed to solve. Sometimes I watch content on my TV by casting it from my Linux PC. Most of that content are rips of my DVD collection, which is thankfully legal in Spain, as far as I...

My XDC 2024 talk about VK_EXT_device_generated_commands
https://invidious.privacyredirect.com/watch?v=ngyBOTi6oHg
Some days ago I wrote about the new VK_EXT_device_generated_commands Vulkan extension that had just been made public. Soon after that, I presented a talk at XDC 2024 with a brief introduction to it. It’s a lightning talk that lasts just about 7 minutes and you can find the embedded video below, as well as the slides and the talk transcription if you prefer written formats.
Truth be told, the topic deserves a longer presentation, for sure. However, when I submitted my talk proposal for XDC I wasn’t sure if the extension was going to be public by the time XDC would take place. This meant...
Weird Lexical Syntax
I just learned 42 programming languages this month to build a new syntax highlighter for llamafile. I feel like I'm up to my eyeballs in programming languages right now. Now that it's halloween, I thought I'd share some of the spookiest most surprising syntax I've seen.
Bespoke solution to monitor power outages at home
When I came home from a 5-days family trip this summer I immediately realized power was off in our flat. The main switch in the electricity panel was down together with one other additional switch. Everything appeared to have happened a few days before we arrived, so a few things in the fridge were ruined and most of the freezer contents had to be discarded. This was despite the fact we have relatives living close by with an emergency set of keys but, as we were completely unaware of the events, we couldn’t ask them to go check.
I thought about what happened and...
