A gentle intro to assembly with Rust
One of the things I’ve wanted to do for a while is really dig into assembly and get into the weeds of how programs actually run. A rework of the asm macro has recently landed in nightly rust so it seemed like a good time.

Fun with Lisp: Programming the NES (2012)
"Low-level programming is good for the programmer's soul." -John Carmack When the complexity of modern computing gets fatiguing, I look back to the simpler machines of my childhood. I grew up surrounded by various 8-bit and 16-bit machines (most of them already a few years outdated at the time),…

Notes on Programming in C – Rob Pike (1989)
What follows is a set of short essays that collectively encourage a philosophy of clarity in programming rather than giving hard rules. I don't expect you to agree with all of them, because they are opinion and opinions change with the times. But they've been accumulating in my head, if not on paper until now, for a…

The upcoming iterator design for Go 1.23
NOTE: This is based on, but completely rewritten, from a Twitter post:https://x.com/TheGingerBill/status/1802645945642799423TL;DR: It makes Go feel too "functional" rather than being an unabashed imperative language.I recently saw a post on Twitter showing the upcoming Go iterator design for Go 1.23 (August 2024)…

I’ve been working on an experimental new C++ language feature tentatively called “metaclasses” that aims to make C++ programming both more powerful and simpler. You can find out about it here: Curr…

Arenas in Rust
At one level, this question is not very fair, because an answer to it as stated would be that one simply does not use doubly linked lists. They have been popular in introductory computer science lectures because they are a neat way to explain pointers in a data structure that's easy to draw on a whiteboard, but they…

Writing Linux Modules in Ada (2016)
In the following series of blog posts I will document my attempts to write Linux modules using the Ada language. In part 1, I will demonstrate how to write in Ada and build a simple "hello world" Linux kernel module. Additionally, I will introduce a basic customized Ada runtime to support our "hello world" module…

Why OCaml? [video]
Here’s a post from a talk I gave this last summer during our internship program about why we use OCaml. It spends a lot of time on how OCaml fits into the space of programming language designs, and why we think OCaml is in a real sweet spot in that design space, especially for the kind of work we do at Jane Street.
