The problem Pattern matching on a large set of literal values looks clean in code but hits a wall at runtime. Every on() call constructs case objects for every arm. With 128 arms, that is 128 object constructions per match call. At 11ns per call, this is fine for one-off use. Inside a hot loop, it is a disaster. // Clean syntax, 128 case objects constructed per call return match(x) | on( lit(0

Show HN: I built a tool that helps predict HN front page success
E aí, gurizada! De uns tempos pra cá, eu percebi um burburinho enorme em torno de uma ferramenta que tem chamado a atenção, e não é por menos: o OpenClaw. Eu, que vivo mergulhado nesse universo de IA e automação, gravei um vídeo recentemente, que está lá no meu canal, assista no YouTube, justamente pra desmistificar essa parada. E hoje, vim aqui no Dev.to pra gente conversar um pouco mais sobre o

llms.txt is a small text file on a documentation site—usually lists what the product is and links to the important Markdown pages. For coding agents, treat it as the canonical URL to open first when upstream behavior is unclear. This post is mostly setup and workflow, not theory.

Sometimes the best UX fix is the one that requires no new infrastructure. Here's how we added YouTube thumbnails and real video titles to ClipCrafter project cards — using only what was already in the database and what YouTube freely provides. Project cards on the dashboard looked like this: Title: YouTube video (8fcJ4Y-uxCw) Thumbnail: none Status badge, timestamp, action buttons Not great. User
