Wordle in Python using literate programming
Rendering the wordle.org file as webpage and including in the docs as-is, because the Sphinx documentation generator doesn’t understand org-mode files, so we couldn’t render this page directly from Sphinx the usual way.

Xilem: An Architecture for UI in Rust
Rust is an appealing language for building user interfaces for a variety of reasons, especially the promise of delivering both performance and safety. However, finding a good architecture is challenging. Architectures that work well in other languages generally don’t adapt well to Rust, mostly because they rely on…

Unix command line conventions over time
ETA, 2022-05-19: I'm happy this blog post has gathered a fair bit of interest. However, this post is as much effort as I'm prepared to put into the topic. I think it would be a good idea to write an essay, article, or even a book, on how syntax of the Unix command line has varied over the years, and in different…

You say “cave dweller debugging”, I say debug logging
There are still many situations where it's not feasible to stop a process, attach the debugger, and start futzing with memory. We can argue over whether this is because the industry didn't learn enough from the Pharo folks later. For now, let's pretend that's axiomatic: a certain amount of debugging (and even testing)…

A Faster Lexer in Go
It's been a while since I've last rewritten my favorite lexical analyzer :-) That post is the last in a series implementing a lexer for the TableGen language in a variety of programming languages, using multiple techniques.

How to build an absurdly backwards-compatible website
Let's face it: the internet is broken. It feels like so much of the web is composed of clickbait, ads, popups, and a toxic amount of JavaScript that you need a modern computer just to get any value out of it. Remember when low-power computers were created for people who were "just browsing the internet?"…

Jax vs. Julia (Vs PyTorch)
A while ago there was an interesting thread on the Julia Discourse about the “state of machine learning in Julia”. I posted a response discussing the differences between Julia and Python (both JAX and PyTorch), and it seemed to be really well received! Since then this topic seems to keep coming up, so I thought I’d…

Go's Concurrency Examples in Java 19
There is no way for your operating system to know exactly how much stack space a thread will need so it allocates an amount on the order of around a kilobyte initially and then around a megabyte once the thread starts to be used. You only have around a bakers dozen gigabytes of RAM, so you can only have give or take…

Why I don't miss React: a story about using the platform
Just over two years ago I left a role at a London based startup where I lead development of a large, React based e-commerce frontend to join Google to work on Chrome DevTools. My initial focus was to introduce Web Components as the new fundamental building block of all new DevTools features and UI. With the recently…

Emacs for Professionals
This is a series of brief articles aimed at teaching Emacs to computer professionals who are unfamiliar with it. I do not dwell on the basics of the user interface, which can be learned from the built-in tutorial. Instead, each article in this series will distill one very specific command line (CLI) tool or technique…
