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…

Clojure builds as an amalgamation of orthogonal parts
The Clojure Core team recently released a new Clojure library, tools.build , that is a culmination of thought around batteries-included build support for Clojure projects.

How many engineers does it take to make subscripting work?
The select part is actually fine. But for updates, especially for complex updates, it could be pretty verbose and far from being ergonomic. What would you say to this syntax instead?

Heuristics for Effective Software Development: A continuously evolving list
Without psychological safety, respect, and trust, none of the following is possible. The way we work, the work we do, and the organizations within which we work are all part of a connected system. You cannot change anything without changing everything. You cannot improve a system by tinkering with the parts. Process…

Sparse Matrices (2019)
A sparse matrix is a matrix that has a value of 0 for most elements. If the ratio of N umber of N on- Z ero ( NNZ ) elements to the size is less than 0.5, the matrix is sparse. While this is the mathematical definition, I will be using the term sparse for matrices with only NNZ elements and dense for matrices with all…

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.
