Rust has fewer memory CVEs than C/C++ — but that's not the whole story. My analysis of what that number actually says, what it doesn't, and how to turn it into a real technical decision.

My Homelab AI Dev Platform: What Problem It Actually Signals and Where the Limits Are

The homelabber community is building local AI dev platforms and the discussion is genuinely interesting. I have some observations that go beyond the initial excitement — and a checklist so you can decide whether the experiment is actually worth it.

The Birth and Death of JavaScript (2014): What Still Holds and What Doesn't

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.
