dev by day, hobbyist gamedev by night. Generalist FOSS contributor. Finnish AuDHD neurodisaster. I like metal, industrial and EBM music, and I love FPS, RPG and spacesim games. Pan enby. Panby?
I love FOSS and Linux. I want to help make gaming better on Linux desktop.
Does not want to talk about "AI", LLMs, cryptoscams.
My opinions are always my own. Like my shitposts.

My job? Computer Sisyphus and Meme Historian. I work on cryptography, FIPS, and open source. I like video games, books, and riding my bike. I use Arch, btw.
I work for Chainguard, but I definitely don't speak for them.
Sometimes you just have to sit back, relax, and let the train wreck itself.

In other words: I do maps on websites, maintaining the Leaflet JS library when I can, but working on Gleo (my own JS+WebGL library) otherwise.
Long-time supporter of Free/Libre/Open-Source Software, as well as Open Data and adjacent subjects.

@[email protected]I’m a tech founder and recovering SysAdmin. I helped found DevOps and grew up in open source. These days I am convalescing from a decade of physical and mental neglect while running Puppet.
I sometimes write about startups, founders, and other topics I like.
I am an angel investor, mostly in areas of expertise (infrastructure and dev tools) and interest (local first software and power tools).
I am generally default-accept on first conversations.

Trans rights are human rights. I boost #BlackMastodon and #MutualAid posts. I also call for alt text for accessibility.

@[email protected]Je suis développeur, principalement #Python, #JavaScript et parfois C et ASM (surtout sur #GameBoy). Je suis aussi adminsys #Linux.
Je dev pas mal de logiciels libres et #OpenSource. Ça va de l'outil de config de souris gaming au générateur de playlist en passant par de l'optimisation d'images ou du shell PHP *hum*…
J'ai également un blog (blog.flozz.fr) sur lequel je poste surtout du contenu tech mais j'aimerais bien diversifier un peu les sujets à l'avenir.
