Our coffee maker decided to reveal programming details.
Saying goodbye to my hoster Host Europe after 19 years. Migrating me to a Microsoft product for email?!

I think flooding the internet with pictures of President #Zelensky meeting a real #King namely King #Charles of the #UK, would really annoy a certain orange mass.
i just realized "spezifisch" is an actual word in german and not just an orange cola flavoured fish
The invasion of Ukraine 3 years ago in case people forgot who started this war. Don't let Putin's lackey in the White House confuse you. #MapoftheWeek https://mapoftheweek.substack.com/p/the-invasion-of-ukraine
mesirii@chaos.social The idea is to write a short story about a pilot who hauls cargo from a faraway planet to Earth. I think it's an okay future, with a twist in the sense of automation and such things.
Kind of a c't magazine short story, probably not longer than that.
The ability to create convincing sci-fi images with AI... awesome. Full geek mode.
For our open-source test automation project Neodymium, we introduced #Lighthouse support for advanced accessibility and performance testing. Because we include Lighthouse support, we got listed on the project page of Lighthouse on GitHub: https://github.com/GoogleChrome/lighthouse?tab=readme-ov-file#related-projects 🎉
Run Lighthouse reports as part of test execution. The best, you can assert the information to ensure WCAG rules or performance numbers aren't broken.
No excuses anymore, just results! 🐧🐧🐧🐧

Enjoy and feedback is appreciated.
Thanks for rating my #jfokus talk 4.52/5.00. Glad you liked it.
"Would have been nice to stop a while on some slides..." I know. Would love to run that as deep-dive. If you have a JUG coming up or company budget, invite me!
" A bit short on time": Sorry, I wanted to convey the reached state of tuning.

Stockholm kicked it up a notch. Finally some snow. #jfokus
How fast can you process a billion rows? The 1BRC challenge went viral in January 2024. While the original solution delivered insane speed but likely resulted in hard-to-maintain code, this talk will guide you through initial tuning steps to achieve a 5x speed improvement. You'll learn about the JDK, the JVM, and your hardware, gaining insights you can apply to everyday challenges.
You'll also learn when not to do that!
P..S. It is a talk without AI!
@infosec812 Looking forward to it. You will miss my talk... 😕
Hello Stockholm, hello #jfokus. Looking forward to the coming week. Trip to Stockholm was nice and punctual enough...
