Beating the compiler
In modern times, everyone knows that writing assembly is a fool's errand: compilers are the result of literal engineer-centuries of work, and they know the processor much better than you do. And yet – one hears rumors. Written in ancient tomes, muttered in quiet watering holes, scrawled on the walls of bygone temples, hinted at by mysterious texts; the rumors paint a specific picture: Compilers ar

Writing a C compiler in 500 lines of Python
A few months ago, I set myself the challenge of writing a C compiler in 500 lines of Python1, after writing my SDF donut post. How hard could it be? The answer was, pretty hard, even when dropping quite a few features. But it was also pretty interesting, and the result is surprisingly functional and not too hard to understand! There's too much code for me to comprehensively cover in a single blog
Lessons from Writing a Compiler
The prototypical compilers textbook is: 600 pages on parsing theory. Three pages of type-checking a first-order type system like C. Zero pages on storing and checking the correctness of declarations (the “symbol tableâ€). Zero pages on the compilation model, and efficiently implementing separate compilation. 450 pages on optimization and code generation. The standard academic literature is most use
Kalyn: a self-hosting compiler for x86-64
Over the course of my Spring 2020 semester at Harvey Mudd College, I developed a self-hosting compiler entirely from scratch. This article walks through many interesting parts of the project. It’s laid out so you can just read from beginning to end, but if you’re more interested in a particular topic, feel free to jump there. Or, take a look at the project on GitHub.

What the hell is Forth?
Forth is perhaps the tiniest possible useful interactive programming language. It is tiny along a number of dimensions: The amount of code required to implement it The size of the code that is generated The amount of memory used The number of features it considers necessary for useful work It is a language that makes complexity painful, but which reveals that a surprising amount can be accomplishe
SQL + M4 = Composable SQL - Emir's blog
Introduction I often work with clients who have large “data lakes†or big star schema style enterprise databases with fact and dimension tables as far as the eye can see. Invariably said clients end up with a substantial SQL codebase composed of hundreds of independent queries with lots of overlap between them. I want to be able to treat SQL repositories like I’d treat other codebases. That is, I’
26 languages in 25 days: Strategy, tactics, logistics
26 programming languages in 25 days, Part 1: Strategy, tactics and logistics Since making a sudden leap from computer science to academic medicine about seven years ago, I haven’t programmed as much. I love what I do in medicine and biology, and I love helping patients. But, I have missed programming – and programming languages. Then I came across the Advent of Code on Mastodon – a series of daily
