Rust goes tier-1 at Microsoft, mold moves to Rust, and Python quietly renames re.match()

Sep 11, 2026 · All editions

1. Rust is now a tier-1 language at Microsoft

   Rust sits alongside C++, C# and TypeScript internally, with more than 100 Microsoft repositories building hybrid Rust and C++ projects through a new compiler backend, `rustc_codegen_utc`, that wires rustc into MSVC's optimizer.

2. Mold's Rust rewrite aims to be Linux's default linker

   Rui Ueyama is rewriting the mold linker from C++ into Rust for its 3.x series, and wants distributions to ship it as `/usr/bin/ld`. He credits AI coding tools with making the rewrite affordable at all.

3. Python 3.15 soft-deprecates re.match() for re.prefixmatch

   Same function, clearer name. Nothing breaks, nothing warns, and no removal is scheduled - but every `re.match()` in your codebase is a place someone may have meant `re.search()`.

4. Chrome moves to a two-week release cadence

   Chrome 153 starts a two-week milestone cycle, down from four. Google says Chrome 149 and 150 alone fixed 1,072 security bugs, as LLMs find flaws at scale.

5. Mistral raises €3B at €21B, led by Samsung

   Nearly double its last round. Mistral plans 1 GW of European compute by 2030 and says it will host rivals' open weights.

6. A tampered strip binary can backdoor all of NixOS

   Researchers built Ken Thompson's trusting-trust attack out of GNU strip rather than a compiler, and used it to backdoor almost every binary in a NixOS installer.

7. Go 1.27 adds generic methods and a faster encoding/json

   Shipped August 19, 2026 with generic methods, a v2 engine under `encoding/json`, goroutine leak profiles and post-quantum signatures.

8. Anthropic's AI formalizes Fermat's Last Theorem in Lean

   Anthropic says an internal model wrote 13 million lines of Lean in 11 days, producing a complete machine-checked proof.
