Writing C in Cython
For the last two years, I’ve done almost all of my work in Cython. And I don’t mean, I write Python, and then “Cythonize” it, with various type-declarations etc. I just, wri…

Icdiff: side-by-side command line diffs
Your terminal can display color, but most diff tools don't make good use of it. By highlighting changes, icdiff can show you the differences between similar files without getting in the way. This is especially helpful for identifying and understanding small changes within existing lines.

Rich Command Shells
Many applications benefit from a mix of a graphical and textual interface. This has ranged from entire environments, like the Lisp Machine and the follow-on Common Lisp Interface Manager (CLIM), to specific applications like Mathematica and others which employ a "notebook interface". There have also been various…

An Experimental New Type Inference Scheme for Rust
While on vacation, I’ve been working on an alternate type inference scheme for rustc. (Actually, I got it 99% working on the plane, and have been slowly poking at it ever since.) This scheme simplifies the code of the type inferencer dramatically and (I think) helps to meet our intutions (as I will explain). It is…

GitHub dropped Pygments
My first-ever open source contribution, a couple years ago, was to a project called Pygments. My motivation? GitHub was displaying Racket source code poorly. Pygments didn't have a Racket lexer. GitHub was using a Scheme lexer for Racket code. The Scheme ...

It's always very tricky when people who aren't educators start banging on about what should or shouldn't be taught in schools. My own school days are but a hazy memory of hormones, angst, and boring homework. Yet here I am, pontificating. With the current "fad" of encouraging children to learn to code, I thought I…

Implementing a web server in a single printf() call
A guy just forwarded a joke that most of us will already know Jeff Dean Facts (also here and here). Everytime I read that list, this part stands out: Jeff Dean once implemented a web server in a single printf() call. Other engineers added thousands of lines of explanatory comments but still don't u
