I happen to be in China for work right now and the censorship here can be really annoying at times. More often than not I surf over socks proxy and ssh tunnel because there are lots and lots of non-political areas of the net that are blocked. For example: I noticed something funny the other day. I wanted to run a quick python script and went to the python page (python.org) to download python for windows to my enterprise box. As soon as you hit the "download" link however, you get an error message (sometimes you are also redirected to google.com.hk) and the entire python.org domain is blocked for some minutes. Seems like the censors here don't want people to use python - probably just not their kind of humor I guess :P

Small clarification: The 'ram' in Wolfram sounds more like it might mean 'Rahm' (cream) - the fatty stuff that swims on top of milk, not simply 'foam'.
