New Limits to FBI Tracking of Cell Phone Users
EvilTwinSkippy writes "According to the Washington Post (free registration), Two Federal Courts have seperately ruled that the FBI may not track the location of cell phone users without proof that a crime has been committed, or is in progress. The cases involve the FBI seeking court orders to track suspects in real-time using the mobile phone network as part of an ongoing investigation." -
Designing a Municipal Wireless Service?
EvilTwinSkippy asks: "I am on a team generating a proposal for the Wireless Philadelphia Initiative. In short I have to figure out how to cover 135 square miles of city with Wifi. I'm reading through the requirements. (Not linking to them, no fair slashdotting the customer, or my employer.) I have already figured out that supporting Wireless B and G simultaneously has to go. As does supporting cars traveling at 60mph. And getting 1MB sustained across the network is a pipedream. In the end, I'm looking down the barrel of designing a network this is projected to have 160,000 users in 5 years, over at least 3000 nodes. I know that Rooftop mesh networks are going to be a large part of the design, as will Linux boxes acting as routers and access points. What massive network issues has 4 years of electrical engineering, and 10 years of hacking routers and servers not prepared me for?" -
AgroWaste to Oil a Growing Market
EvilTwinSkippy writes "Last May Slashdot covered the story of Changing World Tech's opening of a plant that converts agricultural waste to oil. Fortune magazine has picked up the story, and followed up on their success. Apparently the turkey guts are not as profitable to recycle as hoped, the company paying $30-$40/ton for animal offal. They are producing diesel fuel at $80/barrel (compared to $50/barrel for petroleum derived diesel). However, the plant has been successful enough to spawn ventures in Europe and the U.S. A pilot plant in Philadelphia has successfully used the process to safely break down and extract oil from sewage, medical waste, electronics, even leftovers from petroleum refining. The solids are metal, pure carbon, and fertilizer. And aside from gas and oil, the only other thing the system produces otherwise is sterile water."
