Updated version of Colloquy which fixes Python plugins on Leopard

You can find an updated binary distribution of Colloquy here:

http://yiqiang.org/Colloquy.zip

The only modification is that it is linked using -weak_library so that it uses Python 2.5 if it exists on your machine and falls back to Python 2.3 if you're using 10.4. This is needed because Python plugins for Colloquy need the pyobjc bridge, which is in Python 2.5 (as shipped with Leopard), but not Python 2.3.

You can find a sample plugin here:

http://yiqiang.org/sage-devel-trac.py

To install it, drop it into

~/Library/Application Support/Colloquy/PlugIns/

and either restart Colloquy or type /reload plugins.

Sage development funded by Google

Today the Sage team received some very exciting and encouraging news.

Chris DiBona, who is the Open Source Programs Manager at Google, was able to secure funding for several students to work on Sage this summer. The students and the projects are:

Gary Furnish (Rewrite and Vastly Optimize Symbolic Computation)
Mike Hansen (Combinatorial Species)
Robert Miller (Backtracking Algorithms and Permutation Groups)
Yi Qiang (Distributed Computing with DSage)

More details are in the original proposal:

Thanks again to Google and everyone who worked on making this happen!
