Great Firewall of China

Computer experts from the University of Cambridge were able to breach the ÔÇ£Great Firewall of ChinaÔÇØ and also have found a way to use the firewall to launch DoS (Denial of Service) attacks. .
The firewall was tested by sending data packets containing the word "Falun" to it. This word is a reference to the Falun Gong religious group, which is banned in China. By using forged packets, they were able to circumvent the firewallÔÇÖs filters.
Furthermore, the Chinese firewall can also be used to launch denial-of-service attacks. The system can essentially be turned around on the Chinese government. Sites could be blocked that the Chinese government wants people to see and others could be let in.

Spelling SPAM filter

Much of the SPAM I get uses misspelled words. This is probably so
that the messages can pass through Bayesian filters because their
words do not accurately match the words on the list. I would like a
filter that marks all messages as SPAM if they go over a set threshold
of spelling mistakes. I do have a few people in my address book who
send me terribly misspelled messages. Maybe this would encourage them
to spell correctly. Anyway, this is not really a hashed out SPAM
filter plan or anything. It is simply something I was thinking about
over lunch.
