No outro post eu falei sobre coesão. Chegou a hora de falar de acoplamento. alexrios.me/blog/coupling-…

I talked about cohesion; now it's time to talk about coupling. alexrios.me/blog/coupling-…

A velocidade de produção de código aumentou. O senso de design, não. A coesão continua sendo o que o revisor precisa trazer. alexrios.me/blog/cohesion-…

The speed of code production is up. The taste isn't. Cohesion is what the reviewer still has to bring. alexrios.me/blog/cohesion-…

DRY was originally about knowledge, not characters. Two pieces of code can look identical and represent completely unrelated facts about the world. A rule I've used for a decade to filter the "I should DRY this up" instinct. alexrios.me/blog/dry-coinc…

The title says it all.

21% das peer reviews submetidas a uma das conferências mais importantes de machine learning foram inteiramente geradas por IA. Citações alucinadas. Feedback que não engajou com o paper. Ninguém percebeu até alguém resolver checar. Isso está acontecendo na engenharia de software também. Code reviews, RFCs, design docs, demos para os stakeholders. Os rituais continuam. Os artefatos parecem corretos. Mas a fricção produtiva que obriga as pessoas a pensar, defender e aprender desapareceu. Quando a IA gera o artefato, o loop de feedback fica oco. O sênior dá a crítica. O júnior anota. Mas ninguém do outro lado está aprendendo com isso. Escrevi sobre o que quebra quando a gente continua fingindo que processos desenhados pra humanos ensinarem humanos ainda funcionam quando é a IA que gera o trabalho.

While prepping my @gopherconeu talk, I was reading Go's CPU detection code and spotted a one-line nesting mistake that has silently disabled GFNI detection on every consumer-grade Intel CPU shipped since 2021 (Alder Lake, Raptor Lake, the N-series mini-PCs, all of it). The fast path was sitting right there, and Go was reporting false. Wrote up the full story: the line, the hardware, the fix, and what it actually buys users (honest answer: less than the headline suggests, more than you'd think).

New essay! The Floor and the Fractures. The Senior-to-Principal transition is mostly adulthood applied under pressure, plus specific fractures the industry rarely names. The closing section uses Spinoza, which I promise is less pretentious in context than it sounds here. This one is for the patient reader.

People of pi.dev. Do not install.by via any method other than what's shown on the website and in the docs. E.g. we do not publish to brew and never will. Someone else did. We have zero control over what goes into the brew release.

Uma skill viral do Claude Code prometia 75% de economia em tokens, fazendo o assistente falar como um homem das cavernas. Testei contra um prompt de três palavras: "Responda conciso. Seja breve e direto ao ponto." A skill mal ganha das três palavras. Em um dos modelos, perde.
