Tree-Structured Concurrency
For a while now I've been trying to find a good way to explain what structured concurrency is, and how it applies to Rust. I've come up with zingers such as: "Structured concurrency is structured programming as applied to concurrent control-flow primitives" . But that requires me to start explaining what structured…

Antithesis of a One-in-a-Million Bug: Taming Demonic Nondeterminism
With the help of Antithesis, a startup from the founders of FoundationDB, CockroachDB engineers were able to track down and reproduce a most elusive one-in-a-million bug, nearly deterministically!

New ELF Linker from the LLVM Project
We have been working hard for a few months now to rewrite the ELF support in lld, the LLVM linker. We are happy to announce that it has reached a significant milestone: it is now able to bootstrap LLVM, Clang, and itself and pass all tests on x86-64 Linux and FreeBSD with the speed expected of an LLVM project.

Clojure macros continue to surprise me
Clojure macros have two modes: avoid them at all costs/do very basic stuff, or go absolutely crazy.

Playing Fasttracker2 .XM files in JavaScript
Hit the play button above and it will play music; specifically, music composed with (or at least, compatible with) a program released in 1994 called FastTracker 2; this is a Javascript homage I wrote in a fit of nostalgia. The source code is on GitHub if you'd like to check it out.

Kobold, a new web UI crate with zero-cost static DOM
The TodoMVC implemented in Kobold weighs about 30kb when gzipped over the wire, out of which the gzipped Wasm blob is under 20kb. There are no tricks there . I haven't replaced the default allocator, nor have I minified the JavaScript (although I probably should).

Shenanigans With Hash Tables
One reason to know how your data structures work is so that when your problem has unusual constraints you can tweak how they work to fit the problem better or work faster. In this article I’ll talk about four different fun tweaks to the concept of a hash table that I made in the process of using hash tables to…

More fun with reactive-banana-automation
My house knows when people are using the wifi, and keeps the inverter on so that the satellite internet is powered up, unless the battery is too low. When nobody is using the wifi, the inverter turns off, except when it's needed to power the fridge.

Clojure and Deps.edn: A basic guide
After a rather long break from programming and Clojure I decided give them another go. When it comes to managing Clojure projects, Leiningen is de-facto standard tool. Recently, Clojure CLI tools are becoming more and more popular, though. Switching to yet-another-build-tool doesn't have any pragmatic value, but it's…

Memory cache optimizations
When optimizing memory access, and memory cache misses in particular, there are surprisingly few tools to help you. valgrind’s cachegrind tool is the closest one I’ve found. It gives you a lot of information on cache misses, but not necessarily in the form you need it.

Ruby, Ractors, and lock-free data structures
This story is about concurrent data structures in the context of Ruby. The goal here is to demonstrate how true parallelism can be achieved with global mutable state (which at the time of writing, is not supported by built-in Ruby primitives).

Efficient simulation through linear algebra
I spent a lot of time working on a project in which physically plausible simulation of soft materials with pressure chambers was a key part, and in doing so, we managed to improve a part of our simulation by a significant amount. I was very happy with how this small part of the whole system turned out, and I've been…

The Evolution of a Haskell Programmer (2001)
Some time later, I came across Iavor’s "jokes" page, including a funny bit called “ The Evolution of a Programmer ” in which the traditional imperative "Hello, world" program is developed through several variations, from simple beginnings to a ridiculously complex extreme. A moment’s thought turned up the factorial…
