Comecei a estudar tecnologia há pouco tempo e decidi transformar o aprendizado em algo prático. Foi assim que surgiu meu primeiro projeto web publicado: um site voltado para Fonoaudiologia, desenvolvido para apresentar…
JavaScript production errors happen inside minified React and Next.js bundles, so a media team's AI agent can report latency and cost perfectly while its control room shows only an unreadable app.js:1:48392 stack. Those…
Originally published on NextFuture Bạn muốn một chương trình bên ngoài duyệt hoặc chặn từng tool call của coding agent. Trong sáu CLI phổ biến hiện nay, chỉ bốn cái cho bạn làm điều đó — và hai cái trong số đó mặc định…
Originally published on NextFuture Bạn cài model local vì nghe "chạy local là miễn phí". Cài xong, gõ một câu hỏi, rồi ngồi đợi tám giây mới thấy ký tự đầu tiên hiện ra. Miễn phí thì đúng. Nhưng khoảng cách giữa ba lựa…
Most i18n setups ask you to name a string before you have finished writing it. You invent pricing.hero.title, open a JSON file, wire a lookup, then finally type the sentence. Multiply that by a few thousand UI strings…
I typed “The meaning of life” into a browser and, 25.7 seconds later, it answered The fine game of nil Not quite philosophy, perhaps—but it is an exact anagram. Every letter in the original appears once in the result.…

This was a building week, not a migration week. The brand ports slowed down and a brand-new tool took most of the hours: an engine that turns a library of proven ad layouts into finished ads for any brand. Around it,…
Most people meet GenosDB through its P2P side: real-time sync, WebRTC rooms, decentralized apps without a backend. This post is about the other side, the one almost nobody asks about — GenosDB as a plain local-first…
PouchDB is the reason a lot of us believed offline-first was practical at all. It landed in 2012 with a simple, powerful idea: run a database in the browser that speaks the CouchDB replication protocol, and let the two…
