Node.js isn't just "JavaScript on the server." It's a paradigm shift in how we handle I/O. Thirty years in tech taught me to recognize when something genuinely moves the ground beneath your feet.

A 2014 talk predicted JavaScript would die, replaced by ASM.js. A decade later, JS is still alive — but the tension it identified is more real than ever. Here's what's worth extracting, what to ignore, and how to turn it into a concrete technical decision.

I used HyperFrames to build a video about HyperFrames, then published the whole process: source, commands, mistakes, screenshots, audio, captions, renders, and evidence.

navigator.clipboard.writeText looks trivial until your app silently breaks in production with zero visible error. I found 4 cases the docs never mention: insecure context, lost focus, revoked permissions on iOS, and React timing. Here are the real patterns with copyable code.

489 + 506 points on HN. Bun ports to Rust and everyone has a take. I ran the benchmarks on my real stack before opening my mouth. The uncomfortable result: the underlying language matters less than the hype suggests.

Copy Fail hit #1 on Hacker News with 977 points. I reproduced it in my Next.js stack and found something the viral post never mentions: when the clipboard fails silently during a password or token copy, the user has no idea. That's not a UX bug. It's a human error vector with real consequences.

I built a public lab with reproducible benchmarks to measure TypeScript 7 native preview against TypeScript 6 on real repos. The results are interesting, but the more useful story isn't the speedup: it's understanding when it matters, what breaks during migration, and how to test it without exposing private code.

Discriminated unions, branded types, satisfies, infer, Result<T,E>, type predicates, and mapped types — the type system patterns that make entire categories of bugs impossible to write.

I reproduced the tiny LLM experiment that blew up on Show HN: Gemma running in the browser, no API keys, inside my usual stack. Here's everything that broke — and the little that actually worked.
