Pretending OOP Never Happened
OOP, for all its excesses, was a big step forward in software engineering. The way to move past OOP is to replace it with another discipline, not anarchy.

In Praise of AutoHotKey
People think it’s weird that I do all my development on a Windows machine. It’s definitely a second-class citizen experience in the wider development world, and Windows has a lot of really frustrating issues, but it’s still my favorite operating system. This is for exactly one reason: AutoHotKey. AHK is an engine for…

RISC-V OS using Rust: Filesystems
I have taught operating systems at my university, so I will link my notes from that course here regarding the virt I/O protocol. This protocol has changed over the years, but the one that QEMU implements is the legacy MMIO interface.

What if we'd had better HTML-in-JS syntax all along?
I have a theory that a grave mistake was made in 1995 - the decision not to have a neat, succinct and declarative way of representing html elements in javascript. [On reading the hacker news comments this is pretty historically inaccurate, however, I think this article still stands as "look just how close javascript…

Advanced SQL and database books and resources
For people who've worked through Mastery with SQL , a common question I get is "What's next?" If you completed the course and all 150+ exercises, at this point you'll have a very strong grasp of SQL and should be comfortable writing all sorts of complex queries. However, there's more to working with databases…

Revisiting the Business Card Raytracer
What is the most beautiful piece of code you have ever seen? Not only it is subjective, "beauty" is also a word that can mean a lot of things. If we were to be discussing of raw speed, I would bring up the Fast Inverse Square Root [1] . If we were to judge by aesthetic, my answer would be Andrew Kensler's, 1337 bytes…

0xF Rules
I have been writing articles on this website for twelve years. If you were to look at the early versions , you would think it is a fresh-out-of-school project with icons drawn in Microsoft Paint.

When Parallel: Pull, Don't Push
I’ve noticed a small pattern across a few of my projects where I had vectorized and parallelized some code. The original algorithm had a “push” approach, the optimized version instead took a “pull” approach. In this article I’ll describe what I mean, though it’s mostly just so I can show off some pretty videos…
