When the sun will literally set on what's left of the British Empire
A while ago I treated you to a dissertation entitled “Does The Sun Set On The British Empire?”, and concluded that it doesn't. The UK's widely scattered overseas territories, sparse though they are, mean that the sun is still always shining, somewhere in the world, over British territory.

I want a good parallel computer
The GPU in your computer is about 10 to 100 times more powerful than the CPU, depending on workload. For real-time graphics rendering and machine learning, you are enjoying that power, and doing those workloads on a CPU is not viable. Why aren’t we exploiting that power for other workloads? What prevents a GPU from…

A review of Nim 2: The good and bad with example code
I've been using Nim for about 1-2 years now, and I believe the language is undervalued. It's not perfect, of course, but it's pleasant to write and read. My personal website uses Nim .

CubeSats are fascinating learning tools for space
These are CubeSats. Satellites that are going to space—or at least, the ones I have here are prototypes. But these have one thing in common: they're all powered by either a Raspberry Pi, or a microcontroller. There are already Pis in space, like on Mark Rober's SatGus, on GASPACS, and the Astro Pis on the Space…

An inside look at NSA tactics, techniques and procedures from China's lens
Since I reside in a Five Eyes country (Australia) and have publicly presented four cases I led on China’s APT41 attacking organisations in ASEAN , particularly concerning China’s cyber and political strategies, I was curious to explore what China publishes about Five Eyes operations. This led me down a rabbit hole of…

Using the most unhinged AVX-512 instruction to make fastest phrase search algo
Disclaimers before we start For those who don’t want to read/don’t care that much, here are the results. I hope after seeing them you are compelled to read. TL;DR: I wrote a super fast phrase search algorithm using AVX-512 and achieved wins up to 1600x the performance of Meilisearch. The source code can be found here…

When did people favor composition over inheritance?
The phrase "favor composition over inheritance" has become one of those thought-terminating cliches in software design, and I always like to take a deeper look at those to understand where they come from and what ideas we're missing if we just take the phrase at face value without engaging with the discussion that led…

FAWK: LLMs can write a language interpreter
After reading the book The AWK Programming Language (recommended!), I was planning to try AWK out on this year’s Advent of Code. Having some time off from work this week, I tried to implement one of the problems in it to get some practice, set up my tooling, see how hard AWK would be, and… I found I’m FP-pilled.
