As nobody notice that, the new apt-proxy use python (not perl as the old one). This is really a good news because i love Python and the new apt-proxy has some better performance than the oldest perlish one. The key value here is the Twisted Matrix framework, now apt-proxy can download multiple .deb at the time without a bunch of process or other weakness. This is a great new for debian users but specially for twisted developper because i think it’s the first end-user app that use twisted (not speaking about webserver of other developpers geeky stuffs).
– Nobody for a twisted bittorrent server ? This would save a bunch of CPU cycles too !
In all seriousness, there have been many other applications based on Twisted. Divmod is one (even though their service isn’t actually open yet cough!), Shtoom, Infogreater, and various others.
Hum, is shtoom or infogreater a real end-user ? For me the real apps are apps that meet customers :)
