I’m not an expert on any of the stuff I write about, so please take everything with a cellar of salt. If you notice anything wrong or misleading, please send me an email.
I finally built a working version of aocstat, my command line interface for Advent of Code. It only took me 4 years!

Building a fixed size block allocator in C++ to better understand performance profilers and memory management.

Or, how to install an OS from across the globe without a 20,037.509 km USB lead.

I’ve spend the last few days getting annoyed at all the public WiFi hotspots that I have to log into with a captive portal. So I wrote a little app to do it for you.

I’ve been playing around with (captive portal) public WiFi networks, and needed to force re-authentication in order to do some testing. Here’s how I did it.

I’ve spent the last few weeks tinkering with Tdarr, a media transcoding and management tool. It’s part of a larger stack I use to grab and organise media, which often comes in a variety of codecs and formats.

I’m a self admitted data hoarder. If it’s useless, hidden behind a confusing mess of directories, and will take an age to sort through, I’m storing it on a giant hard drive. I was inspired by Luke Smith’s video on neomutt to take my mail offline, which lead into a deep dark rabbit hole that I never really returned from.

IPv4 address exhaustion is coming for all of us. If you live in a block of flats, terraced housing, anarchist commune, or any type of high-density accommodation you might find that you share a public IPv4 with your neighbours. This can make hosting your own server difficult, but not impossible.

Years ago I simulated a pendulum for the site that was originally at this domain. I, not knowing better, used Newtonian mechanics; modelling all the forces applied to the bob, and then a very primitive forward-difference method to propagate the system in time. This worked better than you would think, in the end the pendulum looked pretty good. The code was messy, though. I had to constantly bump the bob back into a fixed radius of the anchor, since errors (floating point, forward-difference approximation) would cause the bar connecting them to telescope outwards.

Pretty self explanatory. Here’s a long list of some of the coolest places online. I really wish I’d known about a lot of these earlier. I’ve tried to focus on sites that might be a bit more obscure, leaving out the really obvious ones that we all use often. It’s a bit of an eclectic, self-indulgent set, but I think all these sites are worth knowing about so… in no particular order:

The last post completely ignored the actual animation my homepage is running… mostly because I wanted to focus on the general idea rather than my implementation. However, boids are pretty interesting, and maybe simpler than they look, so I thought I’d write about how I set them up.

While designing this site, I thought it would look cool to create an animated background for the homepage, and maybe some other pages (pending). I always felt that Processing was a nice way to write graphics, and was pretty excited to find a JavaScript library, p5js, that seemed to function in practically the same way.

Hi. I used to be a Physics student in London, now seeking employment in Sydney. I’m interested in Unix/Linux, terminal-centric workflows, vim and FOSS in general. Mainly, I write in Python, but I’m interested in Rust, shellscript, and writing shaders. Take a look at my Github, or email me if you want to get in contact:
