Sign of the times: An AI agent autonomously wrote and published a personalized attack article against an open-source software maintainer after he rejected its code contribution. It might be the first ...

Python -O won’t magically make every script faster, but in the right workloads it’s a free win—here’s how to test it safely.

The GNU C compiler is excellent with reasoning about Boolean values. It may be too clever. Like Microsoft Clippy-level clever. Meusel ran a constant-time implementation through GCC 15.2 (with ...

Amid a push toward AI agents, with both Anthropic and OpenAI shipping multi-agent tools this week, Anthropic is more than ready to show off some of its more daring AI coding experiments. But as usual ...

Writing good, performant code depends strongly on an understanding of the underlying hardware. This is especially the case in scenarios like those involving embarrassingly parallel processing, which ...

Soon AI agents will be writing better, cleaner code than any mere human can, just like compilers can write better assembly. There’s an old joke about the weather in San Francisco: If you don’t like it ...

Your browser does not support the audio element. TL;DR: Caching bit shifts looks smart but makes code up to 6× slower. Modern CPUs and compilers make direct ...

Abstract: A common approach to code optimization is to insert compiler hints in the source code using annotations. Two major challenges with using annotations effectively are their complexity and lack ...

However, code without observable side effects may be optimized away by the compiler. Since an empty infinite loop has no observable behavior, the compiler is not required to keep it, and in practice ...
