@GergelyOrosz I might be missing something, but where exactly does Spotify work badly? Not trolling. Genuinely curious because I don’t see any issues with it, it just plays the podcasts and music for me as it did before.

🚨 Kyiv is under a massive Russian air attack right now. One of Ukraine’s most sacred landmarks - the historic Kyiv-Pechersk Lavra - is on fire. Putin sends his birthday wishes to Donald Trump.

@AlbertGasull @GergelyOrosz > Languages have nothing to do with wars

Until the moment when a language becomes one of the officially proclaimed reasons to start one.

@GergelyOrosz > All proceeds from this translation went (+will go) to the Ukrainian army

Thank you, Gergely 💙💛

@steipete @theo They really hurt you back then, didn’t they? 🙃

[Serhii Vasylenko @vasylenko]

@GergelyOrosz Yesssss… to fight that, I use a hook that scans every input from me to check for specific words and phrases such as “how about” or “btw, let’s” — to nudge Claude be extra sensitive to planned vs creeping scope, and flag that. And that helps.

@steipete @Cloudflare Are you approaching running Openclaw on their containers infra, or is it something you already figured out?

Found this on Claude Cowork landing page and now I wonder whether it's an easter-egg-thing or really just a placeholder they forgot to remove?..

@GergelyOrosz @SamMorrowDrums Yes, but… In situation 2, dev A built a prototype fast while dev B was keep finding good arguments and shipped nothing. And happens too often to be just an ironic anecdote.

@slobkebap Also in the airport. I am eager to see billboards along the roads with SaaS ads now :-D

@ClaudeDevs Ka-Ching! 🤑

[Serhii Vasylenko @vasylenko]

@GergelyOrosz Well, Yahoo search also works reliably, and Bing… 😃 I mean, maybe it is not that SRE made Google’s the outstanding one.

[Serhii Vasylenko @vasylenko]

@GergelyOrosz For me, AI-assisted writing works well in most cases of long-form writing, when a process matters. I have a setup that interviews me and keeps updating the draft (i.e., ghostwriter), but then full stop, and I take it from there. I also tried for socials -- waste of tokens XD

Part 2 — layers made it universal, harnesses made it run: https://t.co/lqN6qhICMQ

[Serhii Vasylenko @vasylenko]

In Q3 2025, I had an infrastructure migration ahead of me that didn't fit the usual playbook, and I spent the early part of it asking the wrong question about AI agents.
