On Monday I had a badge. On Tuesday my badge was a coaster. The crime? I rewrote “Billing-Quotes,” a sleepy Java microservice with thirteen upstreams, in Rust. p95 got leaner. CPU chilled. Memory dropped. The infra bill blinked smaller numbers like a hotel minibar. And then the CTO told me to bring a box. This is the autopsy of a decision that was technically...")

Here’s How I Finally Won (Created page with "500px For the first three months of learning Rust, I was in a state of constant, low-grade fury. I’m not new to this. I’ve built production systems in Python, Java, and Go. I know what a pointer is. I know what a reference is. I know how to manage memory. Or so I thought. My first 90 days with Rust were not a “learning curve.” They were a war. A war against an enemy that was pedantic, all-seeing, and infuriatingl...")

The feature was small and the release was routine. The angry screenshot from a user was not. Electron had carried me for years.  Then one day my desktop app started feeling like a badly disguised browser tab that refused to close. That was the day I started to take Rust based GPUI seriously.

Yeah, that’s how I felt watching Rust and DPDK square off in the high-speed packet I/O arena. Let’s be honest: packet I/O isn’t exactly the sexiest topic in tech.

But Java Just Did Something Smarter in 2025 (Created page with "In July 2025, I watched a viral X thread: “Rust is eating Java’s lunch — memory safety, speed, no GC.” I felt the FOMO. My team was knee-deep in a high-frequency trading system — 2 million TPS, sub-millisecond latency. Rust looked tempting. Then Java 25 dropped Project Leyden. One config change later, our JVM startup went from 8.2 seconds to 180 milliseconds. No rewrite. No retraining. Just smarter Java. By November 2025, that single upgrade saved us $42,00...")

You lean back, satisfied. Then you rerun it on another machine… and it’s slower. Or worse — it segfaults.
