I kept deploying broken .env files, so I built a tool to catch them You know the feeling. You push to production, the app crashes, and the
C lets you read and write past the end of an array without complaint. Rust refuses. That one design decision is the difference between a crash and a r

At the beginning of July, I launched CDviz Cloud, a hosted version of an open-source CI/CD observability tool I maintain. Three weeks later: zero reve
On Solana, programs are stateless. If your program needs to remember something per user, per game, per config, it needs a deterministic address it can
Let’s be honest. When we talk about migrating a service to Rust, we all envision the same thing: liquid-lightning latency, CPU graphs dropping off a c

When developers switch to Rust from high-level languages like Python or JavaScript, one of the first mental speedbumps is the string system. Why are
An open-source, self-hosted feature flag engine that evaluates flags in-process (sub-microsecond) and syncs every SDK over SSE in under 50ms. Built in
Every build tool profiles its own silo. cargo build --timings will tell you cargo is fine. Ninja's build log will tell you linking is fine. And yet a
A low-latency media gateway in Rust: the client stream runs on QUIC, the carrier stream runs on UDP, and Tokio keeps the heavy CPU-bound transcoding w
