Basics of Futexes
The futex (short for "Fast userspace mutex") mechanism was proposed by Linux contributors from IBM in 2002 [1] ; it was integrated into the kernel in late 2003. The main idea is to enable a more efficient way for userspace code to synchronize multiple threads, with minimal kernel involvement.

URG
If you asked software engineers some of their “least hated” things, you’ll likely hear both UTF-8 and TCP. TCP, despite being 35 years old, is rock-solid, stable infrastructure that we take for granted today; it’s hard to sometimes realize that TCP was man-made, given how well it’s served us. But within every single…

How to design an elliptic-curve signature system
Earlier this month a new paper by Naomi Benger, Joop van de Pol, Nigel Smart, and Yuval Yarom hit the news . The paper explains how to recover secret keys from OpenSSL's implementation of ECDSA-secp256k1 using timing information from "as little as 200 signatures"; ECDSA-secp256k1 is the signature system used by…

Recursion, continuations and trampolines (2017)
How is tail recursion different from regular recursion? What do continuations have to do with this, what is CPS, and how do trampolines help? This article provides an introduction, with code samples in Python and Clojure.

Reflections on Learning Rust by Building Punchtop
To learn Rust, I implemented an audio game. There were some things I liked and some things I didn't. Some things were easy and some were hard. And there were plenty of libraries that were a joy to use.

Linear Algebra of Types (2019)
It gives my brain a pleasant thrum to learn new mathematics which mimics the algebra I learned in middle school. Basically this means that the new system has operations with properties that match those of regular numbers as much as possible. Two pretty important operations are addition and multiplication with the…

Specialising Dynamic Techniques for Implementing The Ruby Programming Language
People who write Ruby programs want to use metaprogramming. It’s part of what makes the language what it is. But in existing implementations of Ruby, metaprogramming is slow. My work focused on making it fast, providing fast tooling for Ruby programmers, and fast support for legacy C extensions.

SpiderMonkey is on a diet
One thing I’ve learnt while working for Mozilla is that a web browser can be characterized as a JavaScript execution environment that happens to have some multimedia capabilities. In particular, if you look at Firefox’s about:memory page, the JS engine is very often the component responsible for consuming the most…

How GCC and Clang handle statically known undefined behaviour
Recently, we had a discussion in our team about undefined behaviour (UB) in C. For those unfamiliar: We say that a program has undefined behaviour when we write code where the language specification doesn't define what should happen during execution. That means compilers can do whatever they like if they encounter…
