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

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”

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

Today I recreated some designs from Polaroid and RadioShack. As ever, I don't load images for any of these designs – everything is styled with fonts and CSS. Here are two designs roughly taken

I've been wanting a feature in YouTube for months now, and finally got to the point where I just decided to make it myself. The problem: if I'm playing a video on my

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

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

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

I bought a camera yesterday. This is the camera I bought:Sony WX-500 Compact Camera. Credit: sony.co.uk.I bought it because I wanted something cheap to point-and-shoot amateur photos of fjords,

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

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

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

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

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

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

In the spirit of fairness, since I've spent so much time using AWS Lambda functions, I thought I'd give Google's latest offering a try. However, following the instructions to create a simple cloud

The preprocessor included with C compilers is a strange beast. By far its most common use is to #include various header files, and to #define static variables for later use. But there's other,

After programming in Java for altogether too long, I've developed a healthy appetite for the humble Enum. There's a problem, though: Python's enum is ugly. Ugly as hell: class Something(Enum): x = 1

I've had an idea brewing for a while. I'd like to be able to use a single command, available on any device with SSH, to load a fresh image of any operating system

So I've finally got around to making a text game! Sort of. Instead of running in a text-based environment like a console and accepting English-language commands as input, I made the decision to

I recently watched Rob Pike's talk on Concurrency Patterns in Go, and was really impressed by how easy it was to make solid concurrent code without relying on threads, mutexes/locks or anything
