Next.js Image Optimization in 2026: `next/image` v4, AVIF by Default, and the Config Changes Teams Miss

Next.js Image Optimization in 2026: next/image v4, AVIF by Default, and the Config Changes Teams Miss This article was written with the assistance of AI, under human supervision and review. Most Next.js image performance problems in 2026 stem from teams upgrading to v4 without understanding the default format switch to AVIF and the breaking configuration changes that silently degrade production pipelines. The next/image component shipped automatic WebP conversion in v3, but v4 prioritizes AVI

Entenda Ponteiros, simples e facil com Go

Lidar com ponteiros pela primeira vez assusta quem vem de linguagens como JavaScript, Python ou Java, onde a gestão de memória é automática Mas a ideia é mais simples do que parece. Toda variável ocupa um espaço na memória, e esse espaço possui um endereço. Um ponteiro é uma variável que guarda o endereço de outra variável, em vez de guardar diretamente o seu valor. x := 10 p := &x fmt.Println(*p) // 10 x guarda 10. p guarda o endereço de x. E *p acessa o valor que está naquele endereço. &: D

Anonymous pastebins are a spam magnet. I gated mine with proof-of-work instead of logins.

Open pastebin, no login, paste text, get a link. That is the whole appeal, and it is also why every anonymous paste service turns into a dumping ground. Bots script the post endpoint and fire off thousands of spam links, phishing kits, leaked credential lists, malware config. The usual fix is to make the thing less anonymous: force an account, bolt on reCAPTCHA, rate-limit by IP. Every one of those punishes the honest one-off user to slow down a bot that just rotates IPs anyway. I wanted a paste

Split a Name Column? The Migration Contract Catches What Review Misses

A migration that looks correct in review can still corrupt data because review sees intent, not edge cases. You read the SQL, it says split the name into first_name and last_name and backfill from the existing column, and you approve it. Then the one-word customer names become empty first names, the three-word names drop their middle names, and the unique constraint on email stays intact only because the bad rows never got tested. The fix is not to stop generating migrations; it is to force ever

You Don't Need More Free Model Quota. You Need a Content-Addressed Cache.

Three identical prompts. Three model calls. Same answer. I saw this in a GitLab CI pipeline that runs a free model over release notes. The prompt template did not change, the model route did not change, and the input did not change. The job simply ran again because another branch was merged. Free quota disappeared. Is that a quota problem? Sometimes. More often it's a caching problem. I started asking a different question: can I prove the request is identical before I make another model call? Th
