You peek at LLVM IR, you squint at Godbolt, you try a few tweaks…and still no SIMD on Apple M-series or modern ARM servers. Let’s solve this properly: * What’s happening? Your loop shape asks for gathers from src + an in-place RMW store to latents. x86 can often paper over this with AVX2 gathers and tolerant alias analys...")

Java is clearly the bottleneck.” Our on-call charts were ugly: * p95 around the “token generation” API was spiking during traffic bursts * JVM CPU looked bad * GC logs were full of minor collections It was easy to blame Java.

You’re three hours into a refactor and everything compiles. Clean. You add one line, just borrowing a string reference, and the compiler explodes with expected named lifetime parameter.

As part of this transition, Canonical introduced sudo-rs, a Rust-based reimplementation of the traditional sudo command.

But love doesn’t pay migration costs, retrain whole teams, or plug smoothly into incumbent toolchains. Big orgs adopt risk policies, not languages.

Obviously, this is not limited to low-level development; thanks to its rich ecosystem of crates, Rust is also a great alternative for web development.

On one hand, the U.S. government agencies publicly call for moving away from C/C++ and transitioning to memory-safe languages like Rust. Large tech companies are also embracing Rust, emphasizing that it leads to safer code. On the other hand, many developers have developed a clear “anti-hype” sentiment — feeling Rust is over-praised and significantly harder to learn than most languages. Amid this...")
