The security technology, known as ASLR (address space layout randomization), randomly arranges the positions of key data areas to prevent malware authors from predicting target addresses. Another new feature coming in Leopard is Sandboxing (systrace), which limits an application's access to the system by enforcing access policies for system calls."

In response to an inquiry made by The Tech regarding the school's recent drop in the rankings, MIT revealed that in past years it had excluded the test scores of foreign students as well as those who fared better on the ACT than the SAT, both violations of the U.S. News rules. MIT's reported first-quartile SAT verbal and math scores for the 2006 incoming class totaled 1380, a drop of 50 points from 2005."

thefickler writes: Nicholas Negroponte, the visionary behind the One Laptop Per Child initiative (OLPC), has publicly expressed his disappointment at the lack of orders for his low-cost computer for poor children. The situation has become so dire that Negroponte will on Monday announce a "Give one, get one" promotion in the US and Canada, where supporters will be able to purchase two XO-1s for $399. They'll get to keep one, while the second one will be given to a disadvantaged child in the developing world. Orders will only be accepted for two weeks between November 12 and November 26. It's promised that the XO-1 will be delivered to the purchaser before Christmas.
