As the title says it, each presentation was filmed, and has just been uploaded for everyone’s pleasure! Here is the two-part video presentation of Twisted, done by Michael SCHERER.

I found a nicely written article about the problems with Ruby, written by a Ruby user, and why he found Python to be really good. There’s even a quote about Twisted!

And, there are a bunch of things available to a Python guy that Ruby just can’t compete with that are of particular interest to me. Two that come to mind immediately are Twisted and Stackless Python. The former was used by others at TurnTide for creating a really powerful SMTP testing tool and the latter was used by TurnTide’s competitor IronPort to build one of the industry’s best MTAs.

I didn’t knew that IronPort was done in Python, even in Stackless Python!

Henrik Thostrup Jensen announced on the Twisted Users mailing list he made two extensions for the Twisted AMP protocol.

Currently there are two types: A dictionary and a list. The types of the element must be specified (key and value can be different in the dictionary), otherwise they are free form, i.e., the keys in the dictionary can have any name, and the list can be of any size. The types can be nested, e.g., you can create a list of list of strings. I use (or will) the latter to return a query result, for which I do not know the row size. This is currently impossible (AFAICT), in the otherwise excellent AMP protocol.

You can get them on http://www.cs.aau.dk/~htj/code/amptypes-0.1.tar.gz

For people that live under a rock, AMP is a new communication protocol for Twisted (added in Twisted 2.5) much lighter/simpler than PB. It is just a request/response protocol over a persistent connection.
