Joins 13 Ways
Relational (inner) joins are really common in the world of databases, and one weird thing about them is that it seems like everyone has a different idea of what they are. In this post I’ve aggregated a bunch of different definitions, ways of thinking about them, and ways of implementing them that will hopefully be…

How to think about async/await in Rust
(This is a section of the lilos intro guide that people seemed to like, so to increase its visibility, I’m lifting it up into its own post and expanding it a bit. I hope this is a useful companion piece to the post on async debugging I posted this morning.))

A toy programming language in 137 lines of Python code
I thought it would be fun to go outside of my comfort zone of web development topics and write about something completely different and new, something I have never written about before. So today, I'm…

Parsing time stamps faster with SIMD instructions
In software, it is common to represent time as a time-stamp string. It is usually specified by a time format string. Some standards use the format %Y%m%d%H%M%S meaning that we print the year, the month, the day, the hours, the minutes and the seconds. The current time as I write this blog post would be … Continue…

Alt-F4 #65 – Factorio visualizer in Unreal Engine 5
Today we’ve got a very fun project to talk about: The FUE5 project, explained in this article by Hurricane. It’s Factorio, but 3D! Dreams do come true sometimes. It’s not quite a game, but more of a stunning re-imagining of its visuals. There’s lots of technical details on how this was achieved, so let’s jump in. What…

Flattening ASTs and other compiler data structures
This is an introduction to data structure flattening, a special case of arena allocation that is a good fit for programming language implementations. We build a simple interpreter twice, the normal way and the flat way, and show that some fairly mechanical code changes can give you a 2.4× speedup.

Tree-Structured Concurrency
For a while now I've been trying to find a good way to explain what structured concurrency is, and how it applies to Rust. I've come up with zingers such as: "Structured concurrency is structured programming as applied to concurrent control-flow primitives" . But that requires me to start explaining what structured…

Racket frustrates me
2024-07-06 I’ve archived this post Looking for the post Racket frustrates me? You can read the original post on The Internet Archive’s Wayback Machine. Why archive this post? It’s been about a year since I published this post and since realized something: I don’t have any skin in the game anymore. My workflow is now…

A trick to eliminate 2π (sometimes)
As a physicist, I’ve learned that the presence of 2 π 2\pi 2 π [▼] [ Or rather τ \tau τ , as it should actually be called . ] in a formula usually spells trouble. It’s kind of annoying to write by hand, easy to forget, and it’s dimensionless, so you can’t easily check if you forgot to divide or multiply by it…
