Internet and computing pioneer Robert Taylor dies
The technology world just lost one of its most prominent innovators. Robert Taylor, best known as the mastermind of ARPAnet (the internet's precursor), has died at 85. As the director of the US military's Advanced Research Projects Agency from 1965 until 1970, he helped pioneer the concept behind shared networks -- he was frustrated with constantly switching terminals and wanted to access multiple networks from one system. While a lot of the credit goes to his team for implementing ARPAnet, he both pushed hard for the project and wrote a legendary 1968 essay that foretold the internet's future: a vast, decentralized grid of connected devices that would reshape communication at just about every level.
Creeper, the first computer virus, is 40 years young today
Forty years ago today is considered by many to be the birthday of the first computer virus. Of course, in the early 1970s they weren't called computer viruses, but that doesn't make Bob Thomas's handiwork any less special. Creeper (named after a character in the old Scooby Doo cartoons) spread from BBN Technologies' DEC PDP-10 through Arpanet, displaying the message: "I'm the creeper, catch me if you can!" and messing with people's printers. One notable difference between this and the majority of viruses was the fact that it deleted old versions as it replicated itself. Incidentally, that would make 2011 the fortieth anniversary of the first antivirus software: called, appropriately enough, Reaper.
DARPA working with Local Motors to crowdsource next-generation combat vehicles
A next-gen Hummer isn't going to build itself, and these days we can't trust our government bodies to come up with all the cool ideas. DARPA is looking for some help, and if you're feeling up to it that can be you. Our favorite Advanced Research Progects Agency has selected a chassis from crowdsource car designers Local Motors (the same one found inside the company's Rally Fighter) and is asking civilians of all shapes and sizes to figure out what shape and size the Experimental Crowd-Derived Combat-Support Vehicle will be. Sure, XC2V doesn't quite roll off the tongue like "Flying Humvee," but it sure does sound a lot more practical. If you want to have your say (and a chance at the $7,500 prize) you'd better hurry up, because submissions are due by March 3rd. Sadly, designs drawn in Crayon on the back of homework are not eligible, otherwise you'd all be fighting for second place.
MIT researchers develop liquid metal battery for the grid and the home
We've see plenty of green power research over the years, from solar plants to underwater turbines , but relying on the sun or the sea for electricity is not without its challenges: the sun doesn't always shine, for instance, and sometimes the water is calm. A group at MIT led by professor Donald Sadoway is developing grid-scale storage solutions for times when electricity isn't being generated. Since these batteries are intended for the power grid instead of cellphones and Roombas, the researchers can use materials not feasible in consumer electronics -- in this case, high temperature liquid metals. Besides being recently awarded a grant from ARPA-E (Advanced Research Projects Agency, Energy) to put these things in green power facilities, MIT has just embarked on a joint venture with the French oil company Total to develop a smaller-scale version of the technology for homes and office buildings.
DHS looking to satellites, mesh networks for emergency communications
Seeking to avoid the communication breakdowns that occurred as a result of the September 11th terrorist attacks and the Hurricane Katrina disaster, the Department of Homeland Security is developing an emergency network that would let officials email one another even in the absence of a cellular infrastructure. The DHS' Advanced Research Projects Agency, which is analogous to the Pentagon's DARPA, is looking at a number of options to keep the data flowing following an emergency, including widespread deployment of mobile mesh networking technology or re-purposing some of the government's legacy satellites to handle terrestrial communications. This latter option is particularly attractive because some sats could offer transfer rates in excess of 100Mbps, and in fact a trial program is scheduled for this summer that will employ modified BlackBerries and Treos to send secure, satellite-based email between Homeland Security officials and the Royal Canadian Mounted Police.[Via Smart Mobs]
