Programmers avoiding generics is a good thing. 05:23 < smw> jessta, and making myself a new vector for every type is not messy? 05:23 < |Craig|> append is generic, so are make and new arn't they? 05:24 < smw> |Craig|, yes they are 05:24 < jessta> |Craig|: using generic functions is nice and easy, writing/reading them is messy 05:24 < |Craig|> those are commonly used, and needed by most code 05:24 < smw> jessta, but it makes all other code much more readable and easy 05:25 < |Craig|> I've written generic stuff in Java.

I like the idea. Scaleable bittorrent tracker. 21:56 < aiju> great for sharing child porn! 21:56 < smw> aiju, nah, you don't want google to know who is sharing that stuff... 21:57 < smw> it would be great if the next time ubuntu came out with a release their torrent tracker was responsive... 21:57 < smw> lol 21:57 < smw> the users DDoSed the torrent tracker. That takes skill! 21:59 < vsmatck> I was working on a program for a while that distributed hash downloading.
