"The institute's twin focus, on quantum theory and gravity, is very close to my heart and central to explaining the origin of the universe," said Hawking.
"I look forward to building a growing partnership between [Perimeter institute] and our Centre for Theoretical Cosmology, at Cambridge. Our research endeavour is global, and by combining forces I believe we will reap rich rewards."
The institute was founded in 2000 with the help of a $100 million donation from Research in Motion co-founder Mike Lazaridis, who gave an additional $50 million earlier this year.

"The fact that weather, sports, news and e-mail sites make up the majority of leading mobile sites shows that mobile internet is mainly about functionality and need at the moment as opposed to the more entertainment and e-commerce-focused makeup of the leading PC-based sites," says Kent Ferguson, a senior analyst with Nielsen Online.
Some interesting demographics:
25% of mobile internet users are aged 15-24 while the same group make up only 16% of PC based internet users;
23% of the PC based internet users are aged 55 or over while the same group make up only 12% of the mobile internet base.

I've always just taken it for granted that rechargeables would be more environmentally friendly and never really put a great deal of thought into how much more green they may or may not be. According to this article, a 2007 study by Bio Intelligence Service (sponsored by a French rechargeable battery maker) claimed that wearing out a single rechargeable battery impacts the environment less by a factor of 28 times. Makes me appreciate them all that much more!
"We have 5 groups of pixels on the screen corresponding to the 5 notes we might need to play," says Ivan Gagne, Systems Engineer with Cyth Systems. "We relied on the light intensity of the pixels in each of those groups. We couldn't rely on the color of the notes because during the game all the notes turn bluish white when you activate star power. We also couldn't rely on the shape of the notes because, at times, they turn into stars. If that light intensity value exceeds a predetermined threshold, we know we need to hold down that key and actuate the strum bar after a predetermined delay while the note travels down the screen to the bottom "play line". If a note was there for more than ~1/4 second the machine activates the whammy bar to score additional points on the sustained notes. There's another threshold where the intensity has to drop before it can consider the note "played" and therefore ready to start playing another note. The imaging, the region of interest, and the light intensity functions were all built into NI's vision toolkit for LabView."

"Knowing immediately where the shots come from means that it eliminates the confusion and allows soldiers to find cover and return fire. It helps to make combat scenarios, especially in urban areas, a lot less confusing. Everybody immediately knows what side of the vehicle or building to jump behind when taking fire." according to Don Steinman at Qinetiq North America.
According to the Telegraph.co.uk "After roadside bombs, snipers have been the biggest cause of the 301 British fatalities in both wars..."
I think it's great that these and other such technical advances are helping our soldiers in the field, yet it still amazes me how the insurgents still manage to inflict casualties despite it all.
