Things I want in a modern relational query language
This was a very old draft I’ve had sitting around for years. The recent discussions of new query languages like Acadia spurred me to revisit, revise, and publish this. I think one of the biggest causes of NoSQL is that… Continue reading →

There's no reason for software to be slow anymore
The other day, I saw a viral tweet saying that people talking about how LLMs are causing slow, bloated, code are going to eat crow once they re-write everything in super-optimized assembly. We're not quite at the point where we want to write everything in assembly , but some variant of what Nolan Lawson said about…

Everyone says assembly is untyped—everyone is wrong
TL;DR: I believe Odin's inline assembly is currently the best out of any language.The most important aspects are of this article listed below.

Bun 1.4 Rust rewrite is not looking good?
I care about Bun. I have been rooting for it since the initial release in 2022. I switched all my development from Node to Bun. I used it in the development of the Nue framework and now with my new project Hertta .
