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 canâ€™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 TurnTideâ€™s competitor IronPort to build one of the industryâ€™s best MTAs.
I didn’t knew that IronPort was done in Python, even in Stackless Python!
