I fixed a bug in Python
About a month ago, I found a bad-behavior bug in the tokenize standard library module, and with help from Aron Griffis, submitted a patch to fix it. Yesterday was a Python bug day, and Ezio Melotti merged my change, so I have officially contributed to CPython!

Build your own summary tool
After Yahoo! acquired Summly and Google acquired Wavii, there is no doubt that auto summarization technologies are a hot topic in the industry. So as a NLP freak, I decided to give a quick overvie…

The Atoms of Programming
In the world of physics, there are many different models that can be used, though typically each of them has different applicability to different contexts. At the small scale, quantum physics is a very useful model, Newtonian physics will yield evidently incorrect predictions so is less valuable. Where a Newtonian…

Master Concurrent Processes with core.async
One day, while you are walking down the street, you will be surprised, intrigued, and a little disgusted to discover a hot dog vending machine. Your scalp tingling with guilty curiosity, you won’t be able to help yourself from pulling out three dollars and seeing if this contraption actually works. After accepting…

Adventures in JIT compilation: Part 1 – an interpreter
This is the first post in a series about JIT compilers. The plan is to take a simple input language and develop some interpreters and JITs for it, in roughtly increasing degree of complexity. It's my hope that by the end of the series readers will have a good understanding of what it takes to develop a JIT compiler…

Cryptic Crossword: Amateur Crypto and Reverse Engineering
Reverse engineering is a special subgenre of computer programming. It's about the closest that I as a programmer get to being a scientist. Gather data, formulate a hypothesis, test, refine, repeat: reverse engineering is basically applying the scientific method to a very, very small knowledge domain. If you've never…

Debugging Lisp, Part 5
This post is for all of the miscellaneous features that arent large enough to get their own individual posts. If you havent read all of them, here are the links to the previous posts on recompilation, inspection, class redefinition, and restarts. One somewhat obscure tool for debugging is SBCLs trace. SBCLs trace goes…
