@henriquebastos Kidlin’s Law at its finest

Great article on Spec driven development's hard limits.

Ver pessoas do software livre caindo nessa historinha do “banimento do Linux” é triste hein…

That gap between what AI feels like and what AI does is where most of the confusion about engineering hiring lives right now. New piece on why the substitution narrative is wrong, and what's actually worth worrying about.

Developers in a controlled study thought AI made them 20% faster. They were actually 19% slower. The perception didn't change even after they saw the data.

A radicalização política americana não é um fenômeno cultural. É um produto industrial. Tem financiadores, linha de montagem e mercado de exportação.

Em 2002, uma organização financiada pelos irmãos Koch registrou o domínio usteaparty.com. Sete anos depois, uma "onda espontânea" de protestos varreria os Estados Unidos.

Amazon is holding a mandatory meeting about AI breaking its systems. The official framing is "part of normal business." The briefing note describes a trend of incidents with "high blast radius" caused by "Gen-AI assisted changes" for which "best practices and safeguards are not yet fully established." Translation to human language: we gave AI to engineers and things keep breaking? The response for now? Junior and mid-level engineers can no longer push AI-assisted code without a senior signing off. AWS spent 13 hours recovering after its own AI coding tool, asked to make some changes, decided instead to delete and recreate the environment (the software equivalent of fixing a leaky tap by knocking down the wall). Amazon called that an "extremely limited event" (the affected tool served customers in mainland China).

A ironia é que quase todo clássico da Disney veio de histórias que não eram dela. O que acontece quando uma empresa constrói um império no terreno comum e depois muda as regras do jogo?

Em 1989, a Disney mandou advogados pra três creches na Flórida. O crime: funcionários tinham pintado Mickey nas paredes pra alegrar as crianças. Exigiram que apagassem tudo.

A maioria das câmaras está vazia. A maior parte do código gerado por IA funciona, ou pelo menos aparenta funcionar. A recompensa por puxar o gatilho é imediata: entregas mais rápidas, métricas melhores, promoções. O custo é adiado e distribuído.

New article: Inside Go's Runtime Scheduler 🚀 How Go runs millions of goroutines on a few OS threads. The GMP model, work stealing, spinning threads, and context switches that take only 50-100 nanoseconds (10-40x faster than OS threads). 👉 internals-for-interns.com/posts/go-runti… #golang
