What's New in POSIX 2024
In the 1950s, computers did not really interoperate. ARPANET has not yet happened (that would become a thing in the 60s), and every operating system was typically tied to the hardware that was meant to run on. Most communication actually happened over telephone, and no company was more present in that space than the…

Real-time audio programming 101: time waits for nothing (2011)
“The audio processing thread is stalling because the client’s implementation of some XAudio2 callback is doing things that can block the thread, such as accessing the disk, synchronizing with other threads, or calling other functions that may block. Such tasks should be performed by a lower-priority background thread…

What you learn by making a new programming language
Every software engineer uses a programming language, usually multiple. Few of us make programming languages. This makes sense, because the work we need to get done can typically be done just fine in the languages that exist. Those already have people making them better. Let's focus on the task at hand.

NPM and NodeJS should do more to make ES Modules easy to use
Coming back to JavaScript and TypeScript after a few years neck deep in Python and Hack, I kept hitting a number of new, cryptic errors when running NodeJS code in my dev environment:

Building a data compression utility in Haskell using Huffman codes
In this post we will implement a data compression program in about 150 lines of Haskell. It will use Huffman coding and handle arbitrary binary files using constant memory for encoding and decoding.

A Love Letter to Tinkerable Software
I work in product growth helping people discover and use great software, currently at SurveyMonkey. In the past I've done it at Prismatic (acq. by LinkedIn), Clara Lending (acq. by Sofi), Right Side Up, Hubstaff. I've also enjoyed consulting with interesting companies like DoorDash, Empower, StitchFix, Calm, Dell…

Why does an extraneous build step make my Zig app 10x faster?
For the past few months, I’ve been curious about two technologies: the Zig programming language and Ethereum cryptocurrency. To learn more about both, I’ve been using Zig to write a bytecode interpreter for the Ethereum Virtual Machine. Zig is a great language for performance optimization, as it gives you fine-grained…

ZX Spectrum Raytracer
I love raytracers; in fact I’ve written half a book about them. Probably less known is my love for the ZX Spectrum , the 1982 home computer I grew up with, and which started my interest in graphics and programming. This machine is so ridiculously underpowered for today’s standards (and even for 1980s standards), the…

Practices of Reliable Software Design
It should have good performance and be able to hold many entries. Reads are more common than writes. I know how I would do it already, but I’m curious about your approach.

Convolutions, Fast Fourier Transform and polynomials (2022)
You may remember from high school what a polynomial is. If so, you may also remember how to multiply two of them. But what if I told you that the method you were taught is slow as F? In this post we will connect polynomials with the Fourier Transform and convolutions, and show you how to multiply polynomials with…

Possibly all the ways to get loop-finding in graphs wrong
In my puzzle collection , there are many games in which you have to connect points together by edges, making a graph, and the puzzle rules say you must avoid making any loop in the graph. Examples are Net , Slant , and some configurations of Bridges (although not the default one). Loopy and Pearl also care about…
