#crossterm (terminal abstraction for #rust) looks really nice at first glance!

#rust I now have code that gives me a list with 24 time zones, one for each full-hour offset from UTC. It's not nice, but my #Java version wasn't nice either (codeberg.org/dtanzer/tzsh...).
I'll push the rust version when at least a few things work.

Probieren wir mal was positiveres, nachdem ich letztens gefragt habe, was euch nervt und was euch Sorgen macht...
Was läuft denn gerade gut für euch oder in der Softwareentwicklung allgemein?
Was macht euch gerade Hoffnung?

Some more playing around with #GameOfLife in #rust - This time, I explored an infinite world, so I also implemented zooming (mous-wheel) and scrolling (keyboard) in the UI. No unit tests, no refactoring, just exploation.

If you'd told me 5 years ago that a fork of VS Code that loses money every time someone uses it could be worth ~$30B, I would have forked VS Code.... Maybe added a Stack Overflow search box or something.

Communicate Design Ideas: Pair Programming / Mob Programming is Knowledge Tranfer
"Pair programming is continuous code review". You have probably heard that one. But it is not the most important reason we do pair programming. We do it because we want to be more effective at deve...

I'm pretty happy with the how the content of my new video about #PairProgramming and #KnowledgeTransfer turned out, end even the filming and editing is - while not great - OK for me.
Which is a bad omen: The more I'm happy with a video, the worse it performs 🤣

I now have a GUI for my #rust #GameOfLife
Will optimize the code a bit and try to test _some_ of the UI code with unit tests.
Then I might record a video, since I did not yet find one on youtube where someone implements it in Rust using #TDD (if you know such a video, please forward it to me).

Die Sozialen Netzwerke verkommen endgültig zu KI-getriebenen Content-Schleudern. #Journalismus
Zerstört YouTube sich gerade selbst? Gute Analyse von @topfvollgold.de zur aktuellen Überflutung von YouTube mit AI-Slop, u.a. durch pseudowissenschaftliche KI-Kanäle wie "Sleepless Historian" und propagandistische Fake-Videos. Und wie leicht man damit Reichweite generiert.

Since yesterday, I'm running #DaVinciResolve in distrobox because it does not work yet on @fedora@fosstodon.org 43.
It works find, but when I switch #Gnome virtual desktops and back, the window is not there anymore - It just disappears, but the process in the distrobox is stll running.

I played around with multi-agent #AI some more: This time I made three claude code processes work together on refactoring some existing code:

All right, I have just made two claude code instances ping-pong pair-program together, and I have a video recording of it.
It was impressive, disappointing and "meh" at the same time.
Maybe for release on peertube/youtube next week.

Anyone claiming AI-generated code doesn't need to be easy for humans to understand is signalling that, not only are they an inexperienced programmer, but they're inexperienced using LLMs to generate code, too. How long can you go before you hit a problem that needs you to spot it and/or fix it?

Finally I can run #DaVinciResolve again - Now in a @fedora@fosstodon.org 42 distrobox. That may be the better solution anyway.
This week, I have two videos that I could release if I manage to finish them: One more where I play around with #AI and one where I talk about #PairProgramming
