Delightfully useless epiphany: Suppose the null-byte is an electron. Then, /dev/zero provides an infinite supply of electrons and /dev/null has an infinite appetite for them. Let's call these devices Vss and Vdd , respectively.
I have recently looked at Julia , a new programming language developed at MIT that promises to be a dynamic programming language that is sui...
I made this today while experimenting with cellular automata parameters , and I found it uniquely beautiful. After a while the patterns stabilise and start to look like a kind of constantly-moving circuit diagram. I call it Chip . The source is on GitHub if you're that way inclined.
We sill start off by walking though the different parts of a GIF file. (The information on this page is primarily drawn from the W3C GIF89a specification .) A GIF file is made up of a bunch of different "blocks" of data. The following diagram shows all of the different types of blocks and where they belong in the…
This post is my attempt to write an easy to understand introduction to the main ideas behind building a real-time col...
A project cannot survive for nearly fourteen years without making some difficult decisions. Sometimes you're right, sometimes you're wrong, but, to be successful you have to learn from each and every one. One of the most difficult decisions made for Dolphin was the deprecation and removal of D3D9 despite it being the…

C is, today, a unique programming language. Surprisingly few people can really program in C and yet many of us have quite strong opinions about it. Buffer overflows, stack smashing, integer overflows — C has many well publicised flaws, and these terms are often bandied about confidently, even by those unfamiliar with…
We believe the true dream of cloud computing is that your code lives in the network itself. Your code doesn't run in "us-west-4", it runs everywhere.
⭐️ A friendly language for building type-safe, scalable systems!
Note: me telling you up front that these are trick questions rather gives the answers away in most cases, but oh well. Questions Question 1 What's the fastest way to sort a jumbled array, given that the array has length N and contains all the integers from 1 to N inclusi...
Update (Feb 17, 2026)—I no longer agree with many statements made in this blog post. I am leaving it here unmodified. See my follow-up: AI can sort of code, can't write .
Why I worry about the effect GitHub Copilot is having and will continue to have on the accessibility of the web at scale.

Kal is a highly readable, easy-to-use language that compiles to JavaScript. It's designed to be asynchronous and can run both on node.js and in the browser. Kal makes asynchronous programming easy and clean by allowing functions to pause and wait for I/O, replacing an awkward callback syntax with a clean, simple…
At the end of January of this year, I switched to a new job, almost exclusively because I was enticed by the idea of being able to write Haskell. The concept of using such an interesting programming language every day instead of what I’d been doing before (mostly Rails and JavaScript) was very exciting, and I’m…
