Fixing memory leaks in popular Python libraries
I was recently able to make a minimal example that reproduced a Celery memory leak.

What Java Modules Are About
When the subject of Java modules comes up in online discussions every so often, I get the sense that many people misunderstand what it is that modules are supposed to do. That's understandable, as the name 'modules' does not evoke the precise purpose of the feature. There are many kinds of modules, even in the Java…

Rare Greek Variables
I scrape Arxiv to find underused Greek variables which can add some diversity to math; the top 10 underused letters are ϰ, ς, υ, ϖ, Υ, Ξ, ι, ϱ, ϑ, & Π. Avoid overused letters like λ, and spice up your next paper with some memorable variables!

What memory model should Rust use?
This blog post discusses a few alternative Rust-language memory models. I hope that this discussion is of value to the Rust community, but in the end, it is their language, so it is also their choice of memory model. This discussion takes the Rust fearless-concurrency viewpoint, tempered by…

Wild claims about K performance
Sometimes I see unsourced, unclear, vaguely mystical claims about K being the fastest array language. It happens often enough that I'd like to write a long-form rebuttal to these, and a demand that the people who make these do more to justify them.
