Explore whether adding the K8S CPU limit will degrade service performance.

Even though we often hear terms like L1, L2, cache block size, etc., most programmers have a limited understanding of what cache really is. This is a beginner-friendly primer on how cache works.

This blog introduces three mechanisms to investigate the execution time of a Maven build. Having a reliable way to measure build execution time can help identify bottlenecks. This in turn helps making effective improvements, thereby contributing to higher developer productivity. Find out how to effectively identify performance bottlenecks in your Maven builds.

I wrote 84 new matmul kernels to improve llamafile CPU performance.

Back in 2019, Nick Fitzgerald published always bump downwards, an article making the case that for bump allocators, bumping “down” (towards lower addresses) is better than bumping up. The biggest reasons for this are bumping up requires 3 branches vs 2 for bumping down and rounding down requires fewer instructions than rounding up. This became the method used for the popular bumpalo crate. In this post, I want to go back and revisit that analysis.
