My personal C coding style as of late 2023
This has been a ground-breaking year for my C skills, and paradigm shifts in my technique has provoked me to reconsider my habits and coding style. It’s been my largest personal style change in years, so I’ve decided to take a snapshot of its current state and my reasoning. These changes have produced significant…

Elixir for cynical curmudgeons
You are seeing this because the administrator of this website has set up Anubis to protect the server against the scourge of AI companies aggressively scraping websites . This can and does cause downtime for the websites, which makes their resources inaccessible for everyone.

Why is Jepsen written in Clojure?
People keep asking why Jepsen is written in Clojure , so I figure it’s worth having a referencable answer. I’ve programmed in something like twenty languages. Why choose a Weird Lisp?

SectorC: A C Compiler in 512 bytes
SectorC ( github ) is a C compiler written in x86-16 assembly that fits within the 512 byte boot sector of an x86 machine. It supports a subset of C that is large enough to write real and interesting programs. It is quite likely the smallest C compiler ever written.

Understanding GPT tokenizers
Large language models such as GPT-3/4, LLaMA and PaLM work in terms of tokens. They take text, convert it into tokens (integers), then predict which tokens should come next. Playing …

I Love Ruby
I've done a lot in my career. From working on business support software to big backend systems and even robotics. If there's been a consistent through-line to my career, it's the Ruby programming language.

Zig is hard but worth it
"I learned Zig in a weekend! …Six hours! …6µs!" say the blissful lizards. Followed by something to the effect of, "It’s easy to pick up because the syntax is so simple."

Vale's first prototype for immutable region borrowing
Three years, two states, and one pandemic ago, I wrote about a very weird idea: what if the type system could track which data existed before a pure call, to eliminate its memory safety overhead? 0

The seven programming ur-languages (2021)
I regularly hear people asking which programming language to learn, and then reeling off a list of very similar languages (“Should I learn Java, C#, C++, Python, or Ruby?”). In response I usually tell them that it doesn’t really matter, as long as they get started. There are fundamentals behind them.

Rust concepts I wish I learned earlier
This past month, I have been enthralled by the Rust programming language given its unique edge for writing memory-safe, modern programs. Over the years, several languages have emerged as the most preferred by engineers to write resilient, backend software. The tides have shifted from Java/C++ into Go and Rust, which…
