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.

Computers were a mistake
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'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.

And honestly, I'm happy for it. Cursor has great UX, everybody should look at what they can steal.. err.. learn from them.
