Ruby's Creed
Every programming language has some fundamental idea(s) that drives its design and evolution. For Haskell that’s functional purity and state-of-the-art static typing, for Erlang that’s distributed programming and fault tolerance, for Clojure that’s simplicity and stability. What all these examples have in common is…

Some C habits I employ for the modern day
Despite it being the first “proper” programming language I learned—by reading K&R front-to-back no less—I don’t write C too terribly often nowadays. Playing resonite has gotten me into writing a load of C# for modding the game, and most of what I do day-to-day is automating the tedium on my computer, which gets…

Things that Idris improves things over Haskell
The 1.0.0 of Idris has been released just a few months back, just enough to start trying out the language and some of the possibilities dependent typing offers. But this post is not about dependent…

The CPython Bytecode Compiler Is Dumb
Due to sheer coincidence of several unrelated tasks converging on Python at work, I recently needed to brush up on my Python skills. So far for me, Python has been little more than a fancy extension language for BeautifulSoup , though I also used it to participate in the recent tradition of writing one’s own static…

Writing a website in Rust
I wanted to create a website for a personal project. This is usually the great opportunity to learn - no time pressure, no external requirements, etc. That meant I could choose the language I wanted to try out in anger (Rust) and take it for a spin. Here’s a short summary of the experience.

Why Python Is Slow: Looking Under the Hood
When I teach courses on Python for scientific computing, I make this point very early in the course, and tell the students why: it boils down to Python being a dynamically typed, interpreted language, where values are stored not in dense buffers but in scattered objects. And then I talk about how to get around this by…

Advanced programming languages (2009)
Students often ask for a recommendation on what language they should learn next. If you're looking for a job in industry, my reply is to learn whatever is hot right now: C++, Java and C#--and probably Python, Ruby, PHP and Perl too.
