writes with a story about research from scientists at MIT, Cornell and elsewhere
showing "that big city taxi systems could be made 40% more efficient with device-enabled taxi sharing. We could cut miles driven, costs, and pollution with the right application of just data and algorithms, and do it while introducing no more than a 5 minute delay to any person's trip. "
Letting such agorithms compete seems an excellent reason to encourage, rather than reject by law, ride-coordination services like Uber and Lyft.Read Replies (0)

writes "A Minnesota school district has agreed to pay $70,000 to settle a lawsuit that claimed school officials violated a student's constitutional rights by viewing her Facebook and email accounts without permission. The lawsuit, filed in 2012 by the American Civil Liberties Union of Minnesota, alleged that Riley Stratton, now 15, was given detention after posting disparaging comments about a teacher's aide on her Facebook page, even though she was at home and not using school computers. After a parent complained about the Facebook chat, the school called her in and demanded her password. With a sheriff deputy looking on, she complied, and they browsed her Facebook page in front of her, according to the report. 'It was believed the parent had given permission to look at her cellphone,' Minnewaska Superintendent Greg Schmidt said Tuesday. But Schmidt said the district did not have a signed consent from the parent. That is now a policy requirement, he said.'"
Asks schwit1, "How is this not a violation of the CFAA?"
It sounds like the school was violating Facebook's Terms of Service

An anonymous reader writes: "Mining new Bitcoins is computationally expensive — you can't expect to do much on your standard home computer. Many miners have built custom rigs to mine more efficiently, but it was only a matter of time until somebody went industrial. Dave Carlson's goal is to mine 10% of all new Bitcoins from now on. He's built literally thousands of units. They collectively use 1.4 million BitFury mining chips, which are managed by a bunch of Raspberry Pis. 'The current rigs each contain 16 boards, with each board containing 16 BitFury chips, for a total of 256 mining chips on each rig. Carlson said about 90,000 processor boards have been deployed, which would put the number of rigs at about 5,600. A new board [being designed] will have 756 chips on each rig instead of 256.' Carlson says his company spent $3-5 million to get everything set up. They current generate 7,000 — 8,000 Bitcoins per month, which, at current rates, would be worth over $4 million."Read Replies (0)
