Lexical differential highlighting instead of syntax highlighting
This type of highlighting is ideal for assembly. With it, the things that shouldn't seem similar usually don't.

Math on GitHub: The Good, the Bad and the Ugly
Finally! On May 19, 2022, GitHub released one of its most requested features: Math support on Markdown! Many had been anticipating this for years, including myself, so much in fact that I wrote a browser extension to get there early. (xhub, it can do a few other things so check it out.)

Learning async Rust with entirely too many web servers
Async Rust is a whole new world of programming. Let's try to understand it by working our way through a series of web servers, learning the details of concurrency and I/O along the way.

I Tried to Reduce Pylint Memory Usage
Through work I have to deal with a pretty huge codebase, and run Pylint on it during our continuous integration process. It's always been a bit slow, but recently I also noticed that it was consuming a lot of memory, causing OOM failures if we tried to run it too much in parallel.

Why bother with argv[0]?
The first argument of a program’s command line, typically reflecting the program’s name/path and often referred to as argv[0], can in most cases be set to an arbitrary value without affecting the process’ flow. Making the case against argv[0], this post demonstrates how it can be used to deceive security analysts…

Making Rust binaries smaller by default
Have you ever tried to compile a helloworld Rust program in --release mode? If yes, have you seen its binary size? Suffice to say, it’s not exactly small. Or at least it wasn’t small until recently. This post details how I found about the issue and my attempt to fix it in Cargo.

Why Clojure?
I’ve programmed systems in many different languages; from assembler to Java. I’ve written programs in binary machine language. I’ve written applications in Fortran, COBOL, PL/1, C, Pascal, C++, Java, Lua, Smalltalk, Logo, and dozens of other languages. I’ve used statically typed languages, with lots of type inference…

Updating the Go Memory Model
The current Go language memory model was written in 2009, with minor updates since. It is clear that there are at least a few details that we should add to the current memory model, among them an explicit endorsement of race detectors and a clear statement of how the APIs in sync/atomic synchronize programs.

Common Lisp Implementations in 2023
Much has been written on Common Lisp; there is rarely one year without someone proclaming the death of the language and how nobody uses it anymore. And yet it is still here, so something must have…

The compositor is evil
First, I want to make it clear that I’m not accusing the compositor of true evil, which I define roughly as deliberately causing suffering. There’s unfortunately too much of that in the world. I mean it in the more metaphorical sense that it causes serious problems and forces other parts of the system to be more…

Writing a GPT-4 script to check Wikipedia for the first unused acronym
Curious what the first ‘unused’ alphabetic acronym is, I have GPT-4 write a script to check English Wikipedia. After three bugs, the first unused one turns out as of 2023-09-29 to be the three-letter acronym ‘CQK’, with another 2.6k TLA unused, and 393k four-letter acronyms unused. Exploratory analysis suggests…
