Reducers, transducers and core.async in Clojure
This is a whirlwind tour of some of the cool new features that appeared in Clojure in the past few years. I find it fascinating how one good idea (reducers) morphed into another (transducers), and ended up mating with yet another, apparently unrelated concept (concurrent pipelines) to produce some really powerful…

Client-side web programming in Haskell: A retrospective
At the beginning of this decade (2010), a few of us Haskellers were exploring how best to do client-side web programming. We didn’t want to write JavaScript. There’s a surprising number of techniques we tried to avoid doing so. There was work coming from academia and industry. Here’s a history of my own experience in…

Scheme Is a Hoot
Lately I've been spending time learning Scheme and using it to implement the concepts I'm learning in my physics classes as time permits. One of the most exciting things I've been doing with this is getting my Scheme to compile to the Web thanks to Hoot. One of the biggest challenges has been the fact that Hoot is…

Why does C have the best file API
Ok, the title is a tongue-in-cheek, but there's very little thought put into files in most languages. It always feels a bit out of place... except in C. In fact, what you get is usually a worse version of C.

Mindset shifts for functional programming (with Clojure)
For more experienced functional programmers, most of this post will seem introductory, but I introduce some more advanced stuff near the end. Functional Programming over Canadian Programming Lately, I've been thinking about this Functional Programming journey I've been on. I thought it started when I was twenty, but

WebAssembly for the Java Geek
When many Java developers hear the word WebAssembly, the first thing they think is “browser technology”. The second thing: “it’s the JVM all over again”. After all, for a Java developer, in-browser apps are prehistory.

A Boggling Return to C
My first real programming class, back in high school, was taught in C. I found it difficult and I remember spending the whole year thinking that I really had no aptitude for programming. I think I got an OK grade in the end, but I felt like I was really struggling compared to the other students in the class. It wasn’t…

Asm.js AOT compilation and startup performance
With the recent announcement of a commercial game shipping using Emscripten and asm.js , I thought it’d be a good time to explain how asm.js is executed in Firefox and some of the load-time optimizations we’ve made since the initial landing of OdinMonkey in March. (OdinMonkey is an optimization module inside Mozilla’s…
