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.
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).

Is your Git repository bursting at the seams? git-sizer is a new open source tool that can tell you when your repo is getting too big. git-sizer computes various Git…
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…
Getting started with shaders: signed distance functions!
The optimizations behind Wasmi 2.0, and how they compare to Wasm3 and Stitch.
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.
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…
Amber on Rails
With the holiday season reaching its apex, we have a few surprises for those of you that have been patiently waiting. The latest release of Dolphin is stuffed with treats. Our first present is presentation - frame presentation, that is. Two new options have arrived and will help users both…
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.
A collection of power user tips for those working with Postgres
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).
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…
Hi all, A quick update on Software Transactional Memory. We are working on two fronts. On the one hand, the integration of the "c4" C l...
As someone who is interested in systems programming, and has experience working with Go, but not with C or C++1, The Odin language is a great fit. Proper systems language Odin is a systems langauge…
Between the Material You design and move to break apart the Chrome browser from ChromeOS, now more than ever, ChromeOS is Linux with Google's desktop environment.
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…
For some inane reason, Github classifies me as a "major open source maintainer", which means I get a free copilot subscription.1 I've been using it for a...
Having worked with Helm for multiple years these 5 shortcomings always bugged my mind. From CRDs updates to multi namespace deployments.
From magical to frustrating in months. Why AI coding agents feel like dial-up internet and what ultra-fast inference could unlock for developer productivity.
One story every computing enthusiast should hear is the lesson ofhow loops and tail-recursion are equivalent. We like recursivefunctions because they’re amen...

I was enjoying some pizza the other day with some buddies that know a bit about my research and understand where I am coming from with regards to my own computing aesthetics. They understand that I have always pushed for the smallest code that I can get, and to simplify
