The weather is getting ugly in #Prague, so better stay inside at #OSSummit EU and visit the #SUSE booth. We still have plushies for you, if you pass our quiz 😉

It's a cool board for experimentation, but I wouldn't buy it nowadays. It's too expensive for the performance that you get out of it. Cool if you have it to run some insanely parallel program, but I wouldn't get it just for that

We're at #OSSummit EU until Friday, showing of the #RISCV Milk-V pioneer, running #openSUSE Tumbleweed. Come over and take a look! We have a RISC-V emulator too, that emulates RISC-V on RISC-V

Heading to #OSSummit EU to showcase the #RISCV MilkV running #opensuse Tumbleweed. And while customizing my badge, I accidentally made a turned Belgian flag. Or a wrong German one 😅

#LinuxDays 2026 is a wrap! We've had a great #opensuse booth experience this year, with many guests loving the geeko plushies. And some great discussions and feedback from users, the kind of things that you only get on a community event. And you get to play #doom on a #Turris Omnia Wifi 6

SD Cards are unfortunately a giant pain in the rear, especially if you power them off suddenly. But my main gripe is the video stack being pretty unstable, especially at resolutions over full HD.

One thing that I really hate about the whole #cloudnative ecosystem, nothing is simple anymore. Deploying a project requires applying five helm charts, three domains, and at the I have another dashboard 😐 I guess I don't see the full picture yet, but it feels like a lot of process & churn
