Oops, i failed to mention that i had only tested it on Linux. Your page seems to refer to a windows product, which appears to be not necessary under linux.

I'm not sure "promiscuous mode" has a meaning on WiFi network: the (almost) equivalent of this is in the WiFi world is the monitor mode. The monitor mode causes your card to capture all packet on the selected WiFi channel.
Additionnally, when not in monitor mode, your network interface will act as an Ethernet interface (the network card driver will rewrite the 802.11 packets to Ethernet packets before passing them up to the protocols stack). Because of this, any sniffer will see normal Ethernet packets. However, in monitor mode, your driver will pass raw 802.11 packets, which you will be able to sniff.
However, i've no clue about how to enable monitor mode under Windows. I've got it to work under Linux with Orinoco, Prism2-based, and Atheros-based cards.

Speed of Light Exceeded? 393

Posted by kdawson on Tuesday March 06, 2007 @03:34AM from the when-pigs-fly-faster-than-light dept.

PreacherTom writes "Scientists at the NEC Research Institute in Princeton, NJ are reporting that they have broken the speed of light. For the experiment, the researchers manipulated a vapor of laser-irradiated atoms, causing a pulse that propagates about 300 times faster than light would travel in a vacuum. The pulse seemed to exit the chamber even before entering it." This research was published in Nature, so presumably it was peer-reviewed. It's impossible from the CBC story to determine what is being claimed. First of all they get the physics wrong by asserting that Einstein's special relativity only decrees that matter cannot exceed the speed of light. Wrong. Matter cannot touch the speed of light in vacuum; energy (e.g. light) cannot exceed it; and information cannot be transferred faster than this limit. What exactly the researchers achieved, and what they claim, can only be determined at this point by subscribers to Nature.

The Death of Clippy 179

Posted by CowboyNeal on Saturday February 10, 2007 @10:03AM from the annoying-desktop-mascots dept.

AppScout interviews Office's Group Program Manager, Jensen Harris on the subject of Office 2007. Harris reveals that Clippy, the bane of all semi-sentient Office users everywhere, is officially dead. The decision apparently revolved not around the passionate hatred for the unfortunate sprite, but simply out of a desire for UI coherency.

MySpace Worm Creator Sentenced 387

Aidan Steele writes "Remember Samy? The creator of the infamous worm was unfortunate enough to be the the target in MySpace's latest litigation. As was said in the earlier story, the script was "written for fun" and caused no damage. The source and technical explanation for the "attack" was not even released until after MySpace had patched the vulnerability. Apparently this was enough to get the 20 year old (19 at the time of writing the worm) three years of probation, three months of community service, pay restitution to MySpace and is also banned from the Internet. Clearly, disclosing security vulnerabilities doesn't pay."
