My style of Haskell programming has been evolving over the 15 years that I have been working with it. It is turning into something that I would like to call “functor oriented programming”. The traditional use of typed functional programming focuses on data types. One defines data types to model the data structures…

The “park bench” panel at the Haskell eXchange last week talked about a lot of things, but some of them can be summarised by the question ...
I’m not sure why I decided to create an Erlang backend for the PureScript compiler.The platform is somewhat interesting, but I didn’t know it, and I don’t ha...
Master JavaScript 'this' keyword: Learn six contexts where 'this' changes value. Essential for OOP and frameworks.
There is a subreddit /r/nononoyes for videos of things that look like they’ll go horribly wrong, but amazingly turn out ok.
A brief example demonstrating my current frustrations with the Go programming language.
I recently gave a talk on the internals of multicore OCaml GC at Jane Street offices in NYC. The slides from the talk are available online . But I felt that the slides alone aren’t particularly edifying. This post is basically the slides from the talk annotated with notes.
As we all (hopefully) know by now, Python 3 made a significant change to how strings work in the language. …

Coding as a non-English speaker, or what Excel, Illustrator, and functional programming can teach us about names.
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…
After immersing oneself in a research area for several years, it’s easy to feel like the heir to a way of looking at the world that is criminally underrated: why don’t more people want what I want? This can be a useful motivation, but it can also lead to ignoring the changing context in which most research sits. So…
Diesel (http://diesel.rs) is an ORM (Object-relational mapper) and Query Builder written in Rust. It supports Postgresql, Mysql and SQLite…

Almost five months ago, I wrote a blog post about my new programming language, Hackett , a fanciful sketch of a programming language from a far-off land with Haskell’s type system and Racket’s macros. At that point in time, I had a little prototype that barely worked, that I barely understood, and was a little bit of…
Introduction to parser combinators. Understand this functional programming concept for building parsers from smaller components.
Recently Julia Evans wrote an excellent post about debugging a segfault in Rust. (Go read it, it’s good) One thing it mentioned was I think “ …
Several months ago, I introduced Gnirehtet , a reverse tethering tool for Android I wrote in Java.
For over twenty years the Java SE Platform and the JDK have evolved in large, irregular, and somewhat unpredictable steps. Each feature release has been driven by one or a few significant features, and so the schedule of each release has been adjusted as needed — sometimes more than once! — in order to accommodate the…
