Nightly Benchmarks: Tracking Results with Codespeed
Background Codespeed is a project for tracking performance. I discovered it when the PyPy project started using Codespeed to track performance. Since then development has been done to make its setup easier and provide more display options. Anyway, two posts ago I talked about running nightly benchmarks with Hudson. Then in the previous post I [...]

Nightly Benchmarks: Setting up Hudson
For some projects, finding out about performance regressions is important. I’m going to write a two part series about setting up a nightly build machine and displaying the generated data. This part is going to cover installation of Hudson, and getting the benchmarks running nightly. I decided to give Hudson a try because I had [...]

One idea that I had while originally working on the sorting algorithm, was to rework the partition function to take into account duplicate elements. I had [...]

NLTK vs MontyLingua Part of Speech Taggers
This is a comparison of the part of speech taggers available in python. As far as I know, these are the most prominent python taggers. Let me know if you think another tagger should be added to the comparison. MontyLingua includes several natural language processing (NLP) tools. The ones that I used in this comparison [...]

I thought to myself, I should be able to speed it up. At the time I was thinking since sorting has been so well researched it’d likely be easy to [...]
