Writing traceroute in 40 lines of Python
We generally think of languages like Python as high-level languages, but that doesn't mean they're not capable of diving down into low-level territory.

Well said.
Python Projects in Users’ Home Directories with wsgi | Code Spatter
Nice technique for lightweight WSGI apps without needing to touch your Apache conf after the initial setup. I'd like to do something like this for my personal site so that it's easier to deploy quick & dirty apps.

Scrapy – Trac
Interesting: “an open source web crawling and screen scraping framework written in Python.”
Rabbits and warrens. - Jason’s .plan
A good introduction to message queues, specifically RabbitMQ.
Candygram
An implementation of Erlang-style concurrency for Python. Processes are implemented on top of threads, unfortunately, so there's a pretty low limit on the level of concurrency, which illustrates the problems with “porting” a concept like this between languages. Still the API is relatively sane, and with some work on the underlying model — perhaps a switch to select/epoll — this could be a very nice addition to the Python concurrency toolkit.
Buildout - software build system reloaded!
zc.buildout, the build isolation system I've been using, has finally grown its own website, with real, actual documentation. Awesome.
Farmdev: What Makes Pylons Stand Out As a Web Framework
A really good summary of what's good about Pylons. I'm glad to see that the recent 0.9.7 release adds “documentation” to the list; all too often, poor or missing documentation cripples an otherwise good chunk of code.
Interlude - Write Python Doctests interactive — BlueDynamics Alliance
Drop into an interpreter in the middle of your doctest. Brilliant!
Whoosh
Pure-Python search engine. Looks like a great idea if you need something simple and don't want to mess with an external service.
Let's talk about Python 3.0
It uses Python 3 or it gets the hose. On a more serious note, James absolutely nails it w.r.t Python 3.
Mock It!: An lxml you can bank on
Finally! easy_install staticlxml and done.
Python Package Index : collective.buildbot 0.3.3
A set of zc.buildout recipes that make it *stupidly* easy to configure and set up a buildbot master or slave — it's literally like six shell commands to get a dummy buildbot going. Totally freeking awesome.
Intro to Unintrusive JavaScript with Django @ Irrational Exuberance

Simple Top-Down Parsing in Python
Fantastic article on building a top-down parser in just a few hundred lines of Python. Read this even if you don't care about parsing: effbot really demonstrates many of the cool idiomatic tricks that makes Python such a pleasure to write and read.
Fusil - Trac
A library for writing fuzz testing programs.
pgmigrate - Google Code
Another database migration tool. This one's not Django-specific (though it will work with Django), but it is PostgreSQL specific. I'm really quite happy with the competition in this space right now; it'll force any eventually Django built-in migration to

Python Package Index : haufe.eggserver 0.1.10
haufe.eggserver is a tiny webfront to a local egg/sourcecode archive distribution directory (eggs and other distribution files stored directly on the filesystem).
Writing Python/C extensions by hand
An exploration of writing a Python/C extension in pure C versus using ctypes. The takeaway is that ctypes is slower, but easier.
xmldiff
“a python tool that figures out the differences between two similar XML files, in the same way the diff utility does” Seems a bit buggy, but might be useful
James Henstridge » Two‐Phase Commit in Python’s DB‐API
Two-phase commit proposal for Python. A bit esoteric, but this could help us crazy ORM weenies a bit.
iCalendar package for Python
Another iCalendar library. This one has perhaps the best API of all the ones I've used and seems to work with all the iCal feeds I've thrown at it.
Python Package Index : magicdate 0.1.3
A plugin for optparse to do fuzzy dates. Lets your CLI scripts take arguments like “—start today —end tomorrow”; very cute.
Python Package Index : Fabric 0.0.3
“… a bit like a dumbed down Capistrano, except it's in Python, dosn't expect you to be deploying Rails applications, …. Unlike Capistrano, Fabric wants to stay small, light, easy to change and not bound to any specific framework.”
Coder Who Says Py: Initial slides for PyCon core development tutorial online
Brett's (preliminary) slides on contributing to Python. I need to prepare something similar for Django.
Writing An Hadoop MapReduce Program In Python - Michael G. Noll
Neat. I hadn't realized that Hadoop map/reduce jobs could be a bog-standard shell script. It's especially cute that testing the job comes down to “cat data | map | reduce”.
[Python-Dev] Monkeypatching idioms — elegant or ugly?
A bit of code from GvR to make monkeypatching look cleaner. Very clever (of course), though I'm not sure how much I like it: I *like* that monkeypatching looks ugly in Python; it makes the monkeypatch code smell more obvious.

TrueCrypt explained
Cryptography makes my head hurt.
Utilitymill's developer comments on the security model
Sounds relatively smart. However, I'd be suspicious of using chroot — I'm told it wasn't especially designed to be a security feature exactly. Were I to do something of this nature, I'd probably use pypy-sandbox.
Front Range Pythoneering: Django on Jython: Minding the Gap
The Front Range Pythoneers strike again: Django now runs pretty well on Jython. This really is a big deal.
Handwriting on the Sky - Export for Python

PyLinda: PyLinda - Distributed Computing Made Easy
An implementation of tuplespaces in Python
PyRTF - Rich Text Format (RTF) Document Generation in Python
RTF generator written in Python. Looks like a docutils writer based on PyRTF should be pretty trivial, and that might make a better reST -> Word workflow than my current reST -> ODF -> OO.org -> Word nonsense.

PyCha - Trac
Python charting package. Yes, it's YA, but this one uses Cairo and looks *nice*.

Apparently Jaiku is using Django internally, which means Google's now using Django in yet another place.
Apple Bits
Scroll to the bottom for extractkeychain.py, a quick script to dump keychain passwords to plaintext (you *are* piping that into GPG/OpenSSL, right?)
The Py Side of Life: String types in Python 3
Some important notes about strings in Python 3. There's a subtle but important change from 3a1: the bytes type is now immutable. This is a good change IMO; the net result sounds very sane.
tranquil - Google Code
Beautifully simple Django/SQLAlchemy integration layer that automatically maps Django models into SQLAlchemy ORM objects. In theory a similar approch would allow SQLAlchemy objects to be exposed as Django models; that would kick ass.
parsedatetime project
From the Chandler project, a Python module to parse “natural” datetime constructs (i.e. “tomorrow”, “next monday”, and even “two weeks from last thursday at noon”). The API is shitty and Java-esque, but the functionality is great.
py-bcrypt - strong password hashing for Python
We should support bcrypt in Django if this module is installed.
Memory Dump » Blog Archive » Zope3 for Djangoers. Part 1: Installation
This looks great. All my Zope knowledge comes from the hairy Zope2 days, so I really need to brush up on the brave new world of Zope.
BabelDjango - Babel - Trac
Interesting work to integrate Django and Babel. Even if you don't need translation, there's some useful date/time/decimal formatting template filters here.
ElementTree: Working with Namespaces and Qualified Names
Required reading for working with namespaces and ElementTree. It's not hard, but there are a lot of details to get right.
From Rails to Django — Myles Braithwaite
“Recently I switched all of my websites to Djanog from Rails and you can see the difference.” Wow, an amazing difference in RAM consumption. Especially surprising given that Python/Django isn't exactly known for low memory usage.
Gruber: “If Python 3.0 ships before Perl 6, I'm going to cry”
Someone order the man some Kleenex; he's gonna need 'em.
The Hand of FuManChu - Storm, SQLAlchemy, and Geniusql
Not sure about the quality of the benchmarks, but I'd nevertheless still like to see how Django stacks up here. Not very well I'd imagine, but Django's always been an 80% ORM anyway, so 80% of the performance would be just *fine* with me.

A nice and simple producer/consumer threadpool utility. Hooray for doing the simplest possible thing.
Pyglet: /trunk/tools/wraptypes
A tool for parsing C header files and generating ctypes wrappers. From the pyglet project, which includes ctypes wrappers for OpenGL. I'm not sure if this is tunned specially for OpenGL, but if it's roughly generic it could save *lots* of time.
lwqueue: Lightweight cross-language message queue system
A stab at a memcached-like message queue. Looks super-simple, and 1000 op/s isn't half shabby.

Frank Liang's hypenation algorithm (i.e. the good one that TeX uses) in Python.
templatemaker - Google Code
Adrian's “reverse template engine:” take a series of files and construct a template that could have been used to generate those pages. Obviously extremely useful for data scraping.

Antonio on Django/Tabblo: “the HP folks doing diligence on us started by asking why we had not chosen Ruby on Rails and came out the other end incredibly impressed with our Django choice.”
gameobjects - Google Code
“Game Objects is a collection of 2D and 3D maths classes, and algorithms for helping in the creation of games with Python. Suitable for PyGame, but independent of it.”
The Future of TurboGears - TurboGears | Google Groups
TurboGears 2.0 will be built on top of Pylons. This is a very good thing for the Python web community. This has majorly cool implications for Django, too, so I better get my butt in gear and start coding.

ModPython/Articles/ExpatCausingApacheCrash - Graham's Project Wiki
Great writeup of *why* expat can cause mod_python to segfault. The mod_php + mod_python crashes that some Djangonauts see happen for exactly the same reason, so the debugging advice here is useful there, as well.

Five things I hate about Python
Inspired by Titus (who was in turn inspired by brian d foy), here’s what I hate about Python. I completely agree with Brian that you can’t trust any advocate who doesn’t know enough to find stuff to hate. Given that I spend a lot of time advocating Python, writing down what I hate seems a good exercise.
