With my newfound of DVD programming I had to create something, and it now actually works:
Introducing the DVDgotchi. A tamagotchi clone implemented entirely using DVD menus. Works on any DVD player (and VLC).
Source code and ISO available on github.com/Koenvh1/DVDg...

One of the things rsync does filter out are all the control characters before 0x20 except for \n and \r (when they appear at the end). This sadly means I can't use ANSI escape sequences to clear the screen. I did manage to play an ASCII version of Bad Apple!!, albeit slightly flickery at times.

In further toying around with the rsync protocol, I have now managed to make it display more or less arbitrary text. Of course I quickly had to recreate the famous scene from The Matrix.
(And for the DNS people, this means I can likely make the DNS over rsync output compatible with dig)

Recently I've been playing The Farmer Was Replaced. There is something quite satisfying about seeing your algorithms come to life, especially as normally I'm too lazy to make a decent visualisation.
In the open source philosophy, here's my final script: gist.github.com/Koenvh1/a8ca...

Some time ago I bought a Stream Deck (I also wrote a blog about it), but I could never actually stream anything to it. That had to change. Recently I've been working on a plugin to stream live video to the Stream Deck. It works remarkably well:

I have the uncanny ability to find really niche things to develop for. This weekend: a dashboard for Dakar Desert Rally. It only shows the speed, but that's all I need. Plus I learnt a thing or two about reverse engineering Unreal Engine and extracting values from running processes.

Last week a parcel by @alexfursuitmaker.bsky.social arrived and I'm chuffed to bits with it - world, say hello to Rakoen (pronounced as Raccoon).

Sometimes the simplest programming projects bring the greatest joy, like this button on my Stream Deck that allows me to turn the fan behind my simracing setup on and off (using a smart plug). It's really nice, especially with summer around the corner.

Good morning! Last weekend I made a clock where it's always 11 AM, just the timezone changes, so I can always say good morning. See it for yourself here: koenvh.nl/playground/1...
