build1 publisherOne report Burn 0.22.0 takes backend generics out of user code, with a benchmark showing model edits recompiling 6.2x faster than in version 0.21. Its API now sits near the planned 1.0 form, so this is the release Rust ML teams should port to and test.

build1 publisherOne report David Heinemeier Hansson's agent-written Rust port of Campfire served 36,120 room-page requests a second to Rails' 217 in 37signals' own benchmark. A parity harness checks its behavior against Rails, but the numbers are company-run and stop short of production traffic.

Google will give vetted defenders and its own teams a Gemini 4 Argon build with no cyber guardrails, saying the model finds and patches critical flaws unaided. Wiz is the first named outside user, and the bug-finding evidence published so far comes from Google's own internal tests.

build1 publisherOne report tuxctl, a Rust system monitor built on Ratatui, let any local user write arbitrary bytes to its operator's terminal in every release before v0.3.0.
