JavaScript – The monkeys in 2013
A monkey. That’s the default name a part in the JavaScript Engine of Mozilla Firefox gets. Even the full engine has its own monkey name, ...
Why I'm Betting On Julia
The problem with most programming languages is they’re designed by language geeks, who tend to worry about things that I don’t much care for. Safety, type systems, homoiconicity, and so forth. I’m sure these things are great, but when I’m messing around with a new project for fun, my two concerns are 1) making it work…
Lisp: More is less
There’s recently been a resurgence of interest in Lisp (specifically, Clojure) in my neighborhood. I have some kind of a fondness for Lisp, but I think some of its characteristics make it poorly suited for use in large programming efforts. Indeed many of the unique properties that Lisp devotees (myself once included)…
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…
Hindley-Milner in Clojure
I wrote a lambda-calculus interpreter and an implementation of Hindley-Milner to type check it.
New release of Self programming language

A Worst Case for Functional Programming?
It's not about technology for its own sake. It's about being able to implement your ideas.
A Clojure Crash Course
It’s time to learn how to actually do things with Clojure! Hot damn! Although you’ve undoubtedly heard of Clojure’s awesome concurrency support and other stupendous features, Clojure’s most salient characteristic is that it is a Lisp. In this chapter, you’ll explore the elements that compose this Lisp core: syntax…
Crash Course on Notation in Programming Language Theory

Dijkstra on Haskell and Java (2001)
In 2001, Edsger W. Dijkstra wrote a letter to the Budget Council of The University of Texas. A PDF is available here , I’ve typed it up so that everyone can read it. Sadly, the curriculum was changed to Java . Relatedly, the algorithmic language Scheme was replaced by Python in MIT’s The Structure and Interpretation…

How Python 3 Should Have Worked (2012)
As a workaday Python developer, it’s hard to shake the feeling that the Python 2 to 3 transition isn’t working. I get occasional requests to make my libraries work in 3 but it’s far from clear how to and when I try to look it up I find all sorts of conflicting advice, none of which sounds very practical.

Clojure 2013 Year in Review
This is my third Clojure year-in-review post. In 2011 I was excited about Clojure 1.3, ClojureScript, and the second Clojure/conj. By 2012 I was blown away by four Clojure conferences, two O’Reilly books, reducers, Datomic, Immutant, and a partridge in a pear tree.
About Python 3
Python community, friends, fellow developers, we need to talk. On December 3rd, 2008 Python 3.0 was first released. At the time it was widely said that Python 3 adoption was going to be a long process, it was referred to as a five year process. We’ve just passed the five year mark.
Clojure vs. Scala
Last week, someone posted a question on the Clojure group asking for a comparison between Clojure and Scala. Since my most popular blog pos...
