[Twisted-Python] Australian Twisted folk at the OSDC: Melbourne Dec 5th - 7th 2005
by Mary Gardiner Aug. 14, 2005

Aug. 14, 2005

The Australian Open Source Developers Conference is being held at Monash University, Caulfield, Melbourne from December 5th to 7th this year. Seems like all of the Tassie Twisted folk are submitting papers and a few others are thinking of submitting or attending. Hence, while it probably won't be even as formally informal (or informally formal?) as the Hobart and Sydney … [View More]

[Twisted-Python] how to delay the response in the protocol.Protocol

Aug. 11, 2005

It seems tmrc.mit.edu is down. (Or is that just some kind of DNS problem in my end?) Is there any other place I can download TwistedSumo-2005-05-25.tar.bz2 or something equivalent from? Due to firewalls and stuff, I have problems using svn at work...
