Exciting stuff in Python 2.5
Python 2.5 alpha 1 is out, and as usual the What’s New in Python 2.5 document provides a pleasant overview of the new features. There are some real treats in there. While I’m hoping that the syntax for conditional expressions will grow on me, I’m looking forward to Partial function application becoming a common Python idiom. Relative imports are going to make Django applications a lot easier to redistribute, and I can’t wait to see all the crazy hacks that result from the introduction of coroutines.

Things I learned at EuroOSCON
Last week was the first ever O’Reilly European Open Source Convention, held in the magnificent NH Grand Hotel Krasnapolsky in Amsterdam. It was the first big budget conference I’d been too (previously I’ve stuck to less expensive affairs such as SxSW Interactive and PyCon) but the money seems to have been well spent. The venue was fantastic and there was a great line-up of speakers, keynotes and panels.

Running Pydoc under mod_python
I’ve written about pydoc before. In my opinion it’s one of Python’s best kept secrets: a way of instantly browsing the properties, methods and documentation strings of any module available to the Python environment. It can even run a local HTTP server to allow for easy browsing of available documentation.

Backporting from Python 2.3 to Python 2.2
We have a home-grown templating system at work, which I intend to dedicate an entry to some time in the future. We originally wrote it in Python 2.2, but upgraded to Python 2.3 a while ago and have since been evolving our code in that environment. Today I found a need to load the most recent version of our templating system on to a small, long neglected application that had been running the original version ever since it had enough features to be usable.

Python doesn’t support a native switch statement. I’ve found myself using the following coding idiom instead recently which seems to work pretty well:
[... 114 words]Python in Mathematics
Python in the Mathematics Curriculum by Kirby Urner is something of a sprawling masterpiece. It really comes in four parts: the first is a history of computer science in education, the second an appraisal of the impact of open source on education and the world at last, the third a dive in to the things that make Python so suitable for enhancing the mathematics curriculum and the fourth a discussion of how computer science and traditional mathematics are likely to play off against each other in the field of high school education.

PHP 5 Release Candidate 1
I haven’t blogged much about PHP in a while because I’ve been up to my nose in mod_python and loving every minute of it. This news is just too important to miss: PHP 5 Release Candidate 1 has been released, bringing the first production-ready release tantilisingly close. While I doubt PHP 5 will tempt me back it’s definitely an exciting upgrade—my biggest complaint with PHP 4 is the brain-dead object model which defaults to copying whole objects rather than passing references, and this is one of the many things addressed by PHP 5. The new libxml2 powered XML features sound really powerful, and SQLite as an on-board database should be ideal for knocking out small stand-alone applications without needing to set up a mySQL database for them.

Advanced Python network programming
Understanding Network I/O, Part 2 by George Belotsky (via The Farm) is the best tutorial on the subject of network programming I’ve seen yet. It provides a detailed explanation of simple threaded network clients, thread pools using the Queue module and asynchronous I/O using both Twisted and Python’s asyncore library—then discusses the strengths and weaknesses of each approach.
