pgrust rewrote Postgres 18.3 in Rust with AI and passed 46,000 regression tests, yet pgbench runs 9x slower and SQLsmith found a segfault in days. Plus Andrew Kelley vs the Bun Rust rewrite, the same day on HN.
Bun PR #30412 merged a Zig-to-Rust rewrite into main: 6,755 commits, 1M+ lines, binaries 3–8 MB smaller. Try via bun upgrade --canary, with notes on the claude/* branch workflow and why memory safety, not speed, drove it.
The latest GlassWorm wave bundles Zig-compiled native binaries in an Open VSX extension and silently installs a second-stage payload across VS Code, Cursor, Windsurf, VSCodium, and Positron.
