Meanwhile in Germany: Deutsche Bahn (Railway Company) says: It's too hot! Don't use our services! We don't trust our ACs either! OR as we say in Germany: an unforeseeable natural disaster.

Das muss man sich mal geben. An allen Ecken und Enden wird privatisiert, inkl. Infrastruktur. Privatisierung heißt oft auch Profitmaximierung, denn Redundanz kostet. Welch Chuzpe, dass ausgerechnet die Frau des ehemaligen Finanzministers (FDP) der Stadt Berlin die Schuld gibt. 🙄

I guessed so 😉 "busy" sounds a bit negative to me, but maybe it's because of those memes..? 😅

Yeah. I understand that they don't give out food that makes your illness worse. But how is this supposed to make it better? Shouldn't that be the idea? 🤔

After 19 years (that's half of my life!) I helped out on a marching performance as a Bariton Horn Player. Last Sunday, 34°C, but it was so fun! How did I not do this for such a long time???

The look on the face of @josepaumard.bsky.social when he sees #null in a #java #collection... Probably the way I would look, too! 😁 #javaBubble #youtube #shorts #meme
José Paumard: why would you put null values in your collections?!?!

Well, I didn't fall for Mistake #11 from @tagir-valeev.bsky.social's book, but quite something similar: Jackson Objects are both mutable AND return the updated self. I took it for being a copy-then-modify-Operation and used the original value elsewhere - which was modified, too. 😬 #java #mistakes

I renamed my #blog to: Ben's build notes. It's a better description for what I do: working on @maven.apache.org I might extend it later this year, so stay tuned. 😉 Articles about some interesting Maven use cases will follow. #Apache #Maven #Java #build #buildtool

Using Google Gemini, ChatGPT, Caddy and a spare (slow) Intel NUC, I created a local #ArchLinux package repo with a few packages compiled to my Ryzen Processor (znver2). Just installed it and will restart now. Wish me luck!
