I had Codex build a CPython bytecode compiler in Rust (`serc`). It emits byte-for-byte identical output on the top 10,000 PyPI packages, 2-4x faster than the CPython implementation. This was entirely an experiment, though we may ship it (opt-in) in uv.

The bug is like a joke. On Alpine Linux, type 257 to 1024 characters of anything and you get root. ๐Ÿ’€

If you divide 1 by 998,001 you get all three-digit numbers from 000 to 999 in order, except for 998.

C macro approach to using optional / default / named function params, using struct designated initializers. Mandatory values are passed first as standard function params (rect in the example). Especially useful when a zero value can be made a valid value.

Fun fact: there is more Python code in Linux kernel than Rust code.
Readers added context they thought people might want to know
The percentages shown are for the entire Linux GitHub repository. There is no Python code in the kernel. Python is used for other purposes such as scripts and tools. github.com/search?q=repo%โ€ฆ x.com/kawpuh/status/โ€ฆ

Huge computer science result: A Tsinghua professor JUST discovered the fastest shortest path algorithm for graphs in 40yrs. This improves on Turing award winner Tarjanโ€™s O(m + nlogn) with Dijkstraโ€™s, something every Computer Science student learns in college.

Fun Fact: the C operator >>= is officially called the "Shrek Operator". Because it's "Shift Right Equal" a.k.a "Shreq". It was named this way because Dennis Ritchie was a huge fan of the Shrek series.
