The answer isn’t just “optimizing.” It’s link-time optimizing — and that’s where the real black magic happens. Let’s go behind the curtain of LTO and ThinLTO, Rust’s secret weapons for squeezing every ounce of speed out of your binaries. First, What Even Is LTO? When you compile a...")

Latency… spiked. Dashboards were green. Users were not. No one got fired. But it was close.

The internet told me it was a labyrinth of lifetimes, a compiler with a personality, and error messages that read like riddles.

Why I Moved to Rust for Cloud Microservices When I first built microservices in Python and Go, I constantly battled performance bottlenecks, memory leaks, and cold start delays.

Last month, I noticed something I didn’t expect: Rust developer adoption doubled in just two years — from 2 million developers in Q1 2022 to over 4 million by Q1 2024. That’s not hype.
