Took Kiro for a ride and built a Bluetooth scanner on Rust. I'm wondering if this fits on an ESP32.

Russland lügt, führt Krieg, lügt und führt Krieg. Eine Dauerschleife aus der Hölle. In der Berichterstattung werden Russlands Behauptungen zu oft nicht klar eingeordnet. Viel zu oft gelingt die russische Desinformation. Ein aktuelles Beispiel. 1/5

Relatively to itself, HTML Minifier Next is by now 4–6 times faster than when the project started (and, therefore, its predecessors).

This comes on top of many improvements.

Try it out—and let me know about issues and suggestions!

The more I use serverless, the less I think about it. The recent announcements around re:Invent finally made it clear why that’s the whole point.

This isn’t really about serverless. It’s about what happens when infrastructure stops asking humans to guess the future.

69% of “State of HTML” survey participants agree that “ensuring my HTML code passes validation is important,” with 12% disagreeing.

Oh I have discovered one issue. Apparently software update needs to be updated. It has not been able to update software update. There will be no software updates until I can update software update.

I AM SHRIEKING 💀🤣

Forget the statue at City Hall, this guy is the *real* Spirit of Detroit. 🫡
A review for a Little Caesar’s somewhere by Kevin S: Stopped into this Little Caesars just trying to get a $6 pizza and ended up in a full on action movie. Just as I grabbed my order, this furious dude barges in yelling about how I cut him off in traffic earlier. Before I can even respond, he throws a punch but then out of nowhere the guy behind the counter jumps over it like he's been waiting for this moment his whole life and just beats the living hell out of the guy. The guy ran off and the cashier just dusted himself off. I said "are you ok man" and he looked me dead in the eye and said "B*tch, this is Little Caesars. We always hot and ready." Five stars. Will absolutely return.

MIT Technology Review wrote about my dystopian backup plan USB stick
Simon Willison has a plan for the end of the world. It’s a USB stick, onto which he has loaded a couple of his favorite open-weight LLMs—models that have been shared publicly by their creators and that can, in principle, be downloaded and run with local hardware. If human civilization should ever collapse, Willison plans to use all the knowledge encoded in their billions of parameters for help. “It’s like having a weird, condensed, faulty version of Wikipedia, so I can help reboot society with the help of my little USB stick,” he says.

I've still never gotten into `fzf` (and maybe I never will!) but I think it's really cool that you can use a fzf 1-liner to make things like this little UI for reviewing git commits

I am completely convinced at this point that getting so rich that nobody's opinion actually matters to you in any practical sense is enormously bad for your mental (and often physical) health

it just short circuits any ability you have to learn from fucking up

Das Lustige daran ist ja, dass die Antifa komplett da war nach dem Mord an Walter Lübcke (und davor auch). Aber das kann Merz nicht wissen, weil er zeitgleich als BlackRock-Aufsichtsratschef mit Geldscheffeln beschäftigt war.

Ich bin wirklich schockiert über die Worte von Friedrich Merz. Das ist so dermaßen bodenlos. Das ist so dermaßen falsch (auch inhaltlich).

Wir sind rhetorisch auf dem Level Trumps angekommen.
