An anonymous reader writes with news that security experts from Spider Labs released a kernel level rootkit for Android devices at DefCon on Friday. "As a proof of concept, it is able to send an attacker a reverse TCP over 3G/WIFI shell upon receiving an incoming call from a 'trigger number.' This ultimately results in full root access on the Android device." The rootkit was developed over a period of two weeks, and has been handed out to DefCon attendees on DVD.

The catch is that these guys don't understand or care much about computers, so the transition has to be as seamless and painless as possible. Actually, they won't care for new things; even the upcoming upgrade to Windows 7 would be a pain and a bother, which is a great opportunity for Linux. I'm not too concerned about software (most of them only need browser, IM, VLC, mail and a Powerpoint viewer for all those fascinating attachments). What I'm concerned about is OS look-and-feel and interface — system bar on the bottom with clock, trash, info on the right, menu on the left, menu items similar to those of Windows. Is it better to shoot for a very targeted distro? Which would you recommend? Are there themes/skins for mainstream distributions instead? I've been looking around the web, and it's hard to gauge which distros are well-done and reasonably active."

mantis2009 writes "When it comes to stopping a cataclysmic Earth vs. asteroid event, social science and international political leaders have more difficult questions yet unanswered than physicists do, according to report delivered at this week's American Geophysical Union meeting. Wired has a discussion of an analysis authored by former astronaut Rusty Schweickart, who worries that the international community is nowhere near ready to begin the complex and inevitably controversial task of deflecting an asteroid on a collision course with Earth. Among the questions to be answered is whether to modify the Partial Test Ban Treaty to allow nuclear weapons in outer space. Another possibility to avoid the destruction of civilization would require the international community to choose an area on the globe where an asteroid might be 'aimed.' Who would decide which nations get placed in the asteroid's crosshairs?"

Joshua writes "Researchers from Japan have calculated Pi to over 2.5 trillion decimals using the T2K Open Supercomputer (which is currently ranked 47th in the world according to a June, 2009 report from Top500.org). This new number more than doubles the previous record of about 1.2 trillion decimals set in 2002 by another Japanese research team. Unfortunately, there still seems to be no pattern."
