Juan TorchiaWhat They Learned Building a Rust Runtime for TypeScript — and What I Can't See Objectively
I've burned myself with Rust and spent posts deep in TypeScript patterns. I'm the worst possible person to be objective here. I read every line anyway — and found three design decisions I think are wrong, and one that's genuinely brilliant.
Juan TorchiaThe Month Anthropic Didn't Respond: Billing, Trust, and the Hidden Cost of AI API Dependency
A 365-point HN thread gave me permission to say what I'd been avoiding: building on AI APIs carries support and continuity risks nobody discusses honestly. I lived it firsthand on a Friday at 11pm.
Juan TorchiaHow They Broke the Top AI Agent Benchmarks — and What That Says About My Stack
I read the paper that exploded on HN about how top AI agent benchmarks get shattered. The problem isn't the models — it's that we're measuring the wrong things and building on sand. Worst part: I recognized the same patterns in my own agents.

Juan Torchia9 patrones de TypeScript que eliminan bugs antes de ejecutar el código
Discriminated unions, branded types, satisfies, infer, Result<T,E>, type predicates y mapped types: los patrones del sistema de tipos que hacen que categorías enteras de bugs sean imposibles de escribir.

Juan TorchiaThings You're Over-Engineering in Your AI Agent (That the LLM Already Handles)
I opened my production repo and counted the lines I wrote to re-implement things the LLM already handles. The number hurts. This post is that autopsy — 340 lines of misplaced confidence.
Juan TorchiaA 'perfectible' language: why the idea is beautiful and why it'll fail anyway
I read a proposal for a language designed to evolve its own syntax and couldn't stop thinking about the three languages I loved, mastered, and had to abandon. Not because they were bad. Because the ecosystem left first.
Juan TorchiaClaude Code Routines: Weeks Ignoring It and I Finally Get Why It Matters
I used Claude Code for weeks without setting up a single routine. Assumed it was overhead for people with too much free time. Then a post hit 611 points on HN and I couldn't look away anymore. Here's what changed — and why the resistance was entirely mine.
Juan TorchiaLa criptografía que usás para firmar digitalmente tiene fecha de vencimiento: qué publicó NIST y cómo migrar tu HSM
NIST finalizó los estándares post-quantum en agosto de 2024. RSA y ECDSA tienen deadline de 2035. Si firmás documentos, JWTs o certificados con un HSM, esto te afecta ahora — te explico ML-DSA, cómo impacta al hardware, y qué hacer esta semana.
Juan Torchia9 TypeScript Patterns That Kill Bugs Before You Run the 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.

Juan TorchiaI Optimized a Docker Image from 1.58GB to 186MB — And Silently Broke Hot Reload for Two Days
I shrunk a Docker image from 1.58GB to 186MB with multi-stage builds. The image was perfect. Hot reload stopped working. Nobody told me for two days. Here's what I broke and how to never repeat it.
