Linux
I've been a GNU/Linux user since '99; though most weeks I use all three main operating systems. I dual-boot my PC with Windows to play PC and especially VR games, but use Linux as my daily driver for software development and pretty much everything that's not gaming. I also use my 2015 Macbook Pro which is still going strong in 2024; mostly I use it for video calls with my family, but it's also my work machine when I'm away from home, and the one you'll see me use for presentations... at least until I find a way of justifying buying a replacement.
This section of my site is where I mostly keep notes to myself on things that took some effort to research that I'm likely to need to do again one day.
