Dear sir, you have built a compiler
I am afraid to inform you that you have built a compiler. I know you wanted a “simple prototype” that would just add that one feature to your programming model. You said that “SSA is an overkill” and “it’s just way too much infrastructure to maintain for a simple task” and yet, six months later, you have pile of…

Automatic supercuts on the command line with Videogrep
I’ve been working on some long-needed updates to Videogrep , my command-line tool that automatically generates supercuts. These updates were motivated in part by a 10 week class I recently developed and taught at the School for Poetic Computation called Scrapism (web-scraping-as-art). The class includes a section on…

Learn TLA+
tl;dr: online TLA+ manual/advanced techniques/examples here. TLA+ is a tool for testing abstract software designs. I first stumbled on it in 2016 and found it so useful I wrote a free online guide to help others learn it. Then I decided the guide wasn’t good enough and wrote Practical TLA+ in 2018. Then I decided the…

The joy of building a ray tracer, for fun, in Rust
TLDR? You can find the code and a bunch of examples on GitHub at dps/rust-raytracer. Over the holiday break, I decided to learn Rust. Rust is a modern systems programming language which has a really interesting type system. The type system can catch broad classes of common programming mistakes - e.g. ensuring memory…

I 10x'd a TI-84 emulator's speed by replacing a switch-case
There’s a javascript emulator for the TI83+, TI84+, and TI84+CSE calculators called jsTIfied, which was written by Christopher Mitchell, founder of the calculator fan site cemetech.net. There’s not a whole lot of reasons to use it over something else if you’ve got a native option available, but if you don’t it’s…

Advice for the next dozen Rust GUIs
A few times a week, someone asks on the #gui-and-ui channel on the Rust Discord, “what is the best UI toolkit for my application?” Unfortunately there is still no clear answer to this question. Generally the top contenders are egui, Iced, and Druid, with Slint looking promising as well, but web-based approaches such…

We're moving on from Firebase
We’ve launched dozens of applications on Firebase, utilized nearly every facet of the platform, and designed a playbook for scaling gracefully. Suffice it to say, it’s proven an invaluable tool for K-Optional Software. As recently as March 2022, our developers were cheering innovations like Firebase Extensions…

CRDT: Fractional Indexing
Collaborative peer-to-peer applications sometimes need to operate on sequences of objects with a consistent order across all peers. For example, a peer-to-peer photo album application might need to sync the order in which photos appear in an album.
