Load Windows ICO files. Apparently PIL has trouble with the most recent versions of the windows .ico format (Vista now embeds PNG images in them)—this clever function deals with the differences and gives back a PIL Image object.
Washington Post Update. Peter Harkins summarises the large number of Django-powered database journalism projects released by the Post since September 2007.
Django now has fast tests. Changeset 9756 switched Django’s TestCase class to running tests inside a transaction and rolling back at the end (instead of doing a full dump and reload). “Ellington’s test suite, which was taking around 1.5-2 hours to run on Postgres, has been reduced to 10 minutes.”
Localbuilder. Gareth Rushgrove’s neat little Python continuous integration tool—it watches a directory for changes, then runs a command when it spots any.
The History of Python (via) “A series of articles on the history of the Python programming language and its community”, being compiled by Guido plus guest authors.
The Django Book: Version 2.0 (via) Adrian’s working on a new edition of the Django Book updated to cover version 1.0. As with the first edition, it will be available free online in addition to a published Apress paperback. The first three chapters are now available.
Rate limiting with memcached
On Monday, several high profile “celebrity” Twitter accounts started spouting nonsense, the victims of stolen passwords. Wired has the full story—someone ran a dictionary attack against a Twitter staff member, discovered their password and used Twitter’s admin tools to reset the passwords on the accounts they wanted to steal.

Represent. Andrei Scheinkman and Derek Willis describe how they built the NYTimes Represent feature using GeoDjango and PostGIS.
pygooglechart. I tried a bunch of Python wrappers for Google Charts and liked this one best.
Represent and GeoDjango. The NYTimes new Represent application is built on GeoDjango.
How to install lxml python module on mac os 10.5 (leopard). Instructions that work! Finally, I can find out what all the fuss is about.
A Few Corrections To “On Packaging”. From Ian Bicking.
On packaging. James Bennett discusses the problems with setuptools (and ruby gems), and recommends Ian Bicking’s pip as a setuptools replacement.
lxml: an underappreciated web scraping library. I just wish I could get the wretched thing to install on OS X Leopard without resorting to MacPorts.
I don't think that Python 3.0 is a bad thing. But that it's displayed so prominently on the Python web site, without any kind of warning that it's not going to work with 99% of the Python code out there, scares the hell out of me. People are going to download and install 3.0 by default, and nothing's going to work. They're going to complain, and many are going to simply walk away.
pyquery. “A jQuery-like library for Python”—implemented on top of lxml, providing jQuery style methods for manipulating an HTML or XML document.
What’s New In Python 3.0. Lots.
Python 3.0. “We are pleased to announce the release of Python 3.0 (final), a new production-ready release, on December 3rd, 2008.”
Django 1.0.2 released. An update to last week’s 1.0.1 release, which I failed to link to. 1.0.2 mainly fixes some packaging issues, while 1.0.1 contains “over two hundred fixes to the original Django 1.0 codebase”. The team are holding up the promise to move to a regular release cycle after 1.0.
The new Lawrence.com. The world’s best local entertainment website, relaunched on Django 1.0 with an accompanying substantial redesign.
Secrets of the Django ORM. An undocumented (and unsupported) method of poking a Django QuerySet’s internal query to add group_by and having clauses to a SQL query.
Python gems of my own (via) Did you know you can pass 128 as a flag to Python’s re.compile() function to spit out a parse tree? I didn’t. re.compile(“pattern”, 128)
Beanstalkd / Python Basic Tutorial. How to get up and running quickly with my favourite light-weight queue server. If only it had persistence...
What’s New in Python 2.6 (via) Python 2.6 final has been released (the last 2.x version before 3.0). multiprocessing and simplejson (as json) are now in the standard library, any backwards compatible 3.0 features have been added and the official docs are now powered by Sphinx (used by Django 1.0 as well). There’s plenty more.
simplejson 2.0.1. Python’s simplejson JSON library got a whole lot faster while I wasn’t looking.
Reia. The most common complaint I see about Erlang is the syntax. Reia is a Python-style scripting language (with a dash of Ruby) that runs on the Erlang virtual machine. Looks promising.
Decorator to limit request rates to individual views. Neat piece of code for public facing web APIs written in Django. Update: some smart criticisms in the comments.
bpgsql. Barry Pederson’s pure Python PostgreSQL client library now ships with a Django backend.
RestView—a class for creating a view that dispatches based on request.method (via) I finally got around to writing up a simple approach I’ve been using for REST-style view functions in Django that dispatch based on request.method.
backup_to_s3.py. I wrote Yet Another S3 backup script today. It’s a thin wrapper about boto that doesn’t do anything particularly impressive, but it fits my brain.
