Twisted is a networking engine written in Python, supporting numerous protocols. It contains a web server, numerous chat clients, chat servers, mail servers, and more.

Twisted is a platform for developing internet applications. While python, by itself, is a very powerful language, there are many facilities it lacks which other languages have spent great attention to adding. It can do this now; Twisted is a good (if somewhat idiosyncratic) pure-python framework or library, depending on how you treat it, and it continues to improve.

With Firefox 3.5 now a stable release (with an update coming soon), I'm turning my attention to the next release, Firefox 3.6. One of the key new features that should be part of that release is the Mozilla Labs project called Ubiquity -- though in Firefox 3.6 it is being called Taskfox.

Ubiquity is interesting tool that enables to developers (and end users) to have commands they can send through the browser in order to execute tasks. The Ubiquity 0.5 update is a major release for the project - and it breaks compatibility with older Ubiquity releases.

In considering the ramifications of a slow denial of service attack against particular services, rather than flooding networks, a concept emerged that would allow a single machine to take down another machine's web server with minimal bandwidth and side effects on unrelated services and ports. The ideal situation for many denial of service attacks is where all other services remain intact but the webserver itself is completely inaccessible. Slowloris was born from this concept, and is therefore relatively very stealthy compared to most flooding tools.
