Windows 2003 and XP vulnerable to LAND DoS attack

LAND attack:
Sending TCP packet with SYN flag set, source and destination IP address and source and destination port as of destination machine, results in 15-30 seconds DoS condition.

Which is funny. The last time the LAND attack was seen was about 8 years ago. It’s a trivial remote DoS and you’d think that even basic QA would check for something like this.

No patch out yet, joy!

Cell architecture explained

Sony, Toshiba and IBM have been quietly developing a new vector-based processing architecture which promises to trash anything Intel and AMD have up their sleeves. This guy has read the patent applications and makes some predictions on what we’re going to be seeing in the PS3.

If this is too hard, then Penny Arcade might do a better job at explaining it for you.
