The goal of Tempest is to provide a consistent, reliable, multi-language API for generating heat-map images based on coordinate data-sets.

pyquery allows you to make jquery queries on xml documents. The API is as much as possible the similar to jquery. pyquery uses lxml for fast xml and html manipulation.

With such a large amount of content, searchability was essential. For this we built a custom technology stack based on Solr, Lucene and Haystack. Then, to keep all the previous links pointing in the right direction, we created a customizable scheme of Django regular expressions and Apache mod_rewrites.

helper for publishing data to Layar augmented reality browser from Django edit

getElementsBySelector is a python function which takes a standard CSS style selector and returns an array of elements objects from the document that match that selector. This is a frequently used function in JavaScript - if you use a library. Its kind of meaning less to have this function in the server side - unless you are doing screen-scarping. Then its very useful. Recently, I had to work on a Django app that does a bit of screen-scrapping - so I created this function to aid me.

python-djvulibre is a set of Python bindings for the DjVuLibre library, an open source implementation of DjVu.

Access the SpiderMonkey JavaScript engine from Python

Pydermonkey’s mission is pretty simple and straightforward: it’s just meant to wrap Spidermonkey’s C API as faithfully as possible—including its debugging API—while enforcing the memory safety that Python is known for. This makes it awfully low-level for casual programmers, but thanks to Python’s awesome support for magic methods, it’s not hard to create high-level wrappers that provide much more convenient bridging between JavaScript and Python code.

in Rails, parts of the model design is actually stored in the database schema instead of in the Ruby code. I have started adding comments in the Rails model classes to be able to remember what properties they have without peeking in the Db. Typically I have a number of half-baked projects on my laptop and from time to time I forget what they do and these comments help me remember.

IMAPClient aims to be a easy-to-use, Pythonic and complete IMAP client library with no dependencies outside the Python standard library.

Django may be the Python web framework getting all the press recently, but web.py is definitely a nice, simple framework. One of the nice aspects of web.py is that it exposes methods for the basic HTTP methods (GET, POST, PUT, DELETE, etc.) and uses these methods to process each request from the client. This approach makes it amazingly easy to write a RESTful API.

Selenium is a suite of tools to automate web app testing across many platforms. It has various pieces (Core, RC, IDE, etc), and I struggled trying to figure out how everything fits together and works. At the end of the day, all I wanted to do was use Selenium from my Python code to drive a browser session.

I simply took the oauth.py module by Leah Culver and wrapped it with some useful functions taken from a similar Twitter app we've done at work.

This project aims to provide an easy to setup continuous integration server and client. The server side infrastructure is built on top of django. The tasks are described using fabric.

What is "parsing"? Parsing is processing a series of symbols to extract their meaning. Typically, this means reading the words of a sentence and drawing information from them. When application programs need to process data that is provided as text, they must use some form of parsing logic. This logic scans the text characters and character groups (words) and recognizes patterns of groups to extract the underlying commands or information.

Easy-to-use regular expression API for Python, where _S() and _R() are the primitives for everything.

I recently wrote simple abstraction for exposing calendar events in Django as iCalendar feeds. It relies on vobject for managing the formatting of the calendar file, so you will need this if you want to try it out. It is available in Debian in the python-vobject package.
