How to protect against Firesheep attacks

Computerworld - Security experts today suggested ways users can protect themselves against Firesheep, the new Firefox browser add-on that lets amateurs hijack users' access to Facebook, Twitter and other popular services via Wi-Fi. 

LimeWire Told to Shut

NEW YORK—Popular file-sharing website LimeWire has been ordered to permanently shut down six months after a federal judge found it liable for copyright infringement on a "massive scale."
In an order Tuesday, U.S. District Judge Kimba Wood in Manhattan entered a permanent injunction, ordering the service to disable the searching, downloading, uploading or file trading of its software and to block the sharing of unauthorized music files.
The lawsuit was brought in 2006 on behalf of the major record labels by the Recording Industry Association of America.
In May, the judge found that LimeWire had violated copyright laws and induced users to infringe on copyrights. She also found Mark Gorton, LimeWire's founder, personally liable.
"Plaintiffs have suffered—and will continue to suffer—irreparable harm from LimeWire's inducement of widespread infringement of their wires," the judge wrote in her order.
In a statement Tuesday, the RIAA said the court will conduct a trial in January to determine damages.
"For the better part of the last decade, LimeWire and Gorton have violated the law," the RIAA said. "The court has now signed an injunction that will start to unwind the massive piracy machine that LimeWire and Gorton used to enrich themselves immensely."
On its website, LimeWire posted a notice that said it was under court order to stop distributing and supporting its software. "Downloading or sharing copyrighted content without authorization is illegal," the notice said.
On its corporate parent's Web site, LimeWire Chief Executive George Searle said the company was "disappointed" with the turn of the events and notes the injunction only applies to the LimeWire.
"We are extremely proud of our pioneering history and have, for years, worked hard to bridge the gap between technology and content rights holders," Mr. Searle said in the statement. "However, at this time, we have no option but to cease further distribution and support of our software."

New Transistor Record

A new transistor, made out of the amazing new nanomaterial graphene (a sheet of carbon atoms just one atom thick)has beaten the record for the fastest transistor at 100 GHz. There have been a number of transistor innovations in the last couple of years, including the recent creation of transistors mimicking brain behavior.
Most of the other graphene-based transistors have been created from flakes of graphene, but this device is more in line with the techniques used by the semiconductor industry. According to Phaedon Avouris, one of the IBM researchers who performed this research, "Our work is the first demonstration that high-performance graphene-based devices can be fabricated on a technologically relevant wafer scale."
Graphene transistors cannot be used in digital circuits, though they can boost an analog signal, such as those used in some forms of imaging technology, like radar and medical scanning. Such technology, once perfected, could allow for major miniaturization and enhancement of such technologies.
