CFP for @kcdbudapest.hu ended last week. I just scrolled through the submitted sessions, and some of the titles genuinely made me laugh. 😄
Lot of great content, so this looks to be yet another great KCD after last year.
If you want to attend, don’t miss the early bird price: kcdbudapest.hu/

Kubernetes networking is complex.
But that doesn't mean it's impossible to understand. Break it down into smaller pieces and you'll see how it all connects.

Built a product in 2 days with AI.
I'm a backend dev who avoids frontend. But I had a problem to solve, so I let Claude Code take the wheel.
Result: talkpulse.app - simple audience feedback for speakers
The honest truth: AI is amazing at writing code. Less amazing at not creating a mess.

I've spent the last two days coding exclusively with Claude Code.
In the end, I haven't even looked at the code, just accepted it if it worked.
I'm looking at the code now and trying to make manual changes: it's not complete crap, but it's close to it.
