A BK-tree is a tree data structure specialized to index data in a metric space . A metric space is essentially a set of objects which we equip with a distance function $d(a, b)$ for every pair of elements $(a, b)$. This distance function must satisfy a set of axioms in order to ensure it’s well-behaved. The exact…
A radically different web server architecture that turned my twenty years of experience in building websites upside down
It seems that every day, some computer monkey comes up with a new and more groovy serialization protocol. In the beginning, there was ASN.1 and XDR, and it was good. I think ASN.1 came first, and l…
One of the things I’ve been doing this quarter is removing Gecko’s dependence on NSPR locks . Gecko’s (non-recursive) mutexes and condition variables now use platform-specific constructs, rather than indirecting through NSPR. This change makes things smaller, especially on POSIX platforms, and uses no dynamic memory…
As of Summer 2024, my article "What Colour are your bits?" has been online 20 years, and people are still linking to it as a benchmark. It's clear that people still care about intellectual property in general and copyright in particular, and the difference, if any, between id...
Going through the steps of using cargo fuzz to find bugs in Rust projects
At work there is a tradition of a Friday quiz being posted by the winner of the previous week. I missed out on the most recent one due to having to duck off early to do my tax but the problem was …
Whilst writing a previous blog post I stumbled across the .NET Interpreter, tucked away in the source code. Although, it I’d made even the smallest amount of effort to look for it, I’d have easily found it via the GitHub ‘magic’ file search:
Almost 11 years after we created CodePlex, it’s time to say goodbye. We launched CodePlex in 2006 because we, like others in the industry, saw a need for a great place to share software. Over the years, we’ve seen a lot of amazing options come and go but at this point, GitHub is the de […]
Let’s explore some basic concepts that will help us create a simple chess AI:
Floating-point math puts a big overhead on a computer that doesn't have a floating-point coprocessor; but we really do need floating-point for all but the simplest operations— or do we?? Can we really do things like trig, log, and square-root functions without floating point?
Demonstrating how a weak session secret can allow an attacker to take control of a server

Online payment processing for internet businesses. Stripe is a suite of payment APIs that powers commerce for businesses of all sizes.
Alone on a Friday night, in need of some inspiration, you decide to relive some of your past programming conquests. The old archive hard drive slowly spins up, and the source code of the glory days scrolls by... Oh no. This is not at all what you expected. Were things really this bad? Why did no one tell you? Why were…
I posted curl is C a few days ago and it raced on hacker news, reddit and elsewhere and got well over a thousand comments in those forums alone. The blog post has been read more than 130,000 times so far. Addendum a few days later Many commenters of my curl is C post struck … Continue reading Yes C is unsafe, but… →
Suppose you’re writing a non-GUI C application intended to run on a number of operating systems: Linux, the various BSDs, macOS, classical unix , and perhaps even something as exotic as Windows. It might sound like a rather complicated problem. These operating systems have slightly different interfaces (or very…
Hello! This is part one of a short series of posts on writing a simple raytracer in Rust. I’ve never written one of these before, so it should be a learning experience all around. So what is a raytracer anyway? The short version is it’s a computer program that traces the paths of simulated rays of light through a…
