Your First Day of Ultra-Wealth Imagine waking up one day and being told: “Every second you’re awake, you can spend £50.”What would you spend it on? If you’re like me, your first thought would be
Guard Clauses and the List Monad Some Haskell code on StackOverflow with appealingly concise syntax turned out to be surprisingly deep, and teach me a new type! Here's the code (collated from https://stackoverflow.com/a/20644753): So by
Monads and Do-Blocks in Python Functional programming is a bit like writing regular expressions, in that the effort-expended-per-character is really high. It’s always annoyed me how Enlightened Functional Programmers online love to use bizarre names like “ap”
Hashtables in C: Table Doubling After revising some data structures recently, I thought it'd be an interesting challenge to write some of them in C. I started with a linked list, and then went on to use the

Pose, FLIP, Animations! I've been learning to use Hooks, and I thought it'd be a good time to get my head around the popular Pose declarative animations library. Animations have always been something I've shied away
60fps Parallax Animation with SVG Try it out here!I mainly made this because I wanted to try out drawing in Illustrator, but I've also wanted to try recreating Github's cursor-based parallax (seen on their 404 pages) for
Animating Lines with SVG I've never actually used SVG before, which seems like a gap in my knowledge – I'm pretty comfortable with CSS now (see my recreation of a MacOS security modal), and I've tried my hand

Crazy Idea #78: Full-Stack Elm Architecture I've recently dug into using Redux with React apps, and it's got tons in common with Elm – both have an 'immutable state tree' and represent changes to that tree using Actions. Elm has
TinyBuf: Binary Serialization After reading some of Google's ProtoBuf documentation, and working extensively with Apache Thrift, I decided I could learn most effectively by creating my own proof-of-concept binary serialization framework. I would work in a
Functional Inventory Design I'd like to write a story game in Elm, along the lines of my previous browser game 5:28. However I'd like to design it with a modern frontend framework, rather than stringing
Calculating Logarithmic Semitone Cents While writing a blog post about phone keypad sounds, I realised I'd never done the maths to work out how semitone cents would be split up logarithmically. So here's a run-down of how
Phone Keypad Tones I've always been interested in phone keypad sounds, so I tried to replicate them. Here's what I managed to work out just by ear: Each key has a unique sound The unique sound
Bewitching the Coding Interview A spoof. With thanks (and apologies) to Aphyr. The interviewer greets you as you step into the bright, open workspace. Sunlight streams onto his rugged, handsome face as he introduces himself. “Kris”, he
How to Render a Fractal, Fast Recently I've been working on a project I've called Brot, after the Mandelbrot set. It started out as a simple image renderer, but soon blossomed into a full-scale video zoom renderer: The code
$1.20: A Serverless Spending Tracker Since moving to London, I've built a handful of tools to help me keep on top of my finances. They're not finished, or even particularly polished, but they're incredibly handy! Partly as a
Profiling Hashtables in C Hashtables are a neat way of storing (key, value) pairs with fast lookup, insertion and deletion times. I've written a simple implementation of a hashtable with a view to making an extremely easy-to-understand
