Python
Long time no blog. I’d like to break the ice with a lighthearted Python code readability optimization discussion. I need a Python function that generates short, random, numeric codes of a specified length using a secure random number generator. The codes must not start with 0, but the output should be a string. This was [...]
There has been a lot of discussion in the Pylons/Pyramid community about the concept of traversal. Some people, when faced with traversal for the first time, get confused and want it removed from Pyramid. They want Pyramid to support only routes, a different way of achieving a similar goal. Personally, I think traversal is simpler [...]
… and I think I just wrote it. For years, I have wanted a Python TCP server framework with the following features. Multi-process: I want the framework to be able to use all available processors and cores with no GIL (global interpreter lock) contention. This is important for CPU-bound applications. Multi-threaded: Each process should have [...]
I’ve been working on a cool project for the past year. I haven’t been able to share much about it, but now that it’s open to the public, I intend to talk about it and explore it in the open. It’s built on Python, Repoze.BFG (to be replaced with Pyramid soon), PostgreSQL, Buildout, and a [...]
This test compares the speed of various object serializers available for Python. I should have run it long ago. It opened my eyes a bit! import time import json import simplejson import marshal import pickle import cPickle import cerealizer def time_module(module): d = {} for k in range(100000): d[str(k)] = -k start = time.time() enc [...]
I’ve been racking my brains to find something to present at PyCon 2010. I have been trying to find something good to present since PyCon 2003, when I last presented at PyCon. (I talked about Ape, the Adaptable Persistence Engine for Zope.) I really liked the experience of presenting and it led to a lot [...]

I have been working on a project based on repoze.bfg. BFG is a system for building web software and it has deep Zope roots. (Incidentally, the BFG 9000 weapon in Doom and Quake is quite fun. For stress relief, it’s better to play against the computer rather than people on the Internet because the computer [...]
At the Zope sprint held during PyCon 2009, we had a multi-day discussion about the Zope publisher. Some people were expecting a fight between Jim and me about the best way forward. So what happened? Read on!

I have been planning to compare mod_wsgi with paste.httpserver, which Zope 3 uses by default. I guessed the improvement would be small since parsing HTTP isn’t exactly computationally intensive. Today I finally had a good chance to perform the test on a new linode virtual host. The difference blew me away. I couldn’t believe it [...]
I like to believe that I am a competent software developer in both Python and Java. As a competent developer, I find that certain things are generally much easier than other things. For instance, I just spent a frustrating week working out how to install a Shibboleth identity provider, yet I never got it working [...]
