"In September, the FBI shut down the Silk Road online drug marketplace, and it started seizing bitcoins belonging to the Dread Pirate Roberts — the operator of the illicit online marketplace, who they say is an American man named Ross Ulbricht. The seizure sparked an ongoing public discussion about the future of Bitcoin, the world's most popular digital currency, but it had an unforeseen side-effect: It made the FBI the holder of the world's biggest Bitcoin wallet. The FBI now controls more than 144,000 bitcoins that reside at a bitcoin address that consolidates much of the seized Silk Road bitcoins. Those 144,000 bitcoins are worth close to $100 million at Tuesday's exchange rates. Another address, containing Silk Road funds seized earlier by the FBI, contains nearly 30,000 bitcoins ($20 million)."
"Pennsylvania police this week were pulling people to the side of the road, quizzing them on their driving habits, and asking if they'd like to provide a cheek swap or a blood sample — the latest in a federally contracted operation that's touted as making roads safer. The same operation took place last month at a community in Texas. Then, drivers were randomly told to pull off the road into a parking lot, where white-coated researchers asked if they'd like to provide DNA samples for a project that determines what percentage of drivers are operating under the influence of drugs or alcohol at given times. With uniformed police in the background, the researchers also offered the motorists money — up to $50 or so — for the blood or saliva samples."
"According to a news release from Purdue University, 'Researchers are developing computers capable of "approximate computing" to perform calculations good enough for certain tasks that don't require perfect accuracy, potentially doubling efficiency and reducing energy consumption. "The need for approximate computing is driven by two factors: a fundamental shift in the nature of computing workloads, and the need for new sources of efficiency," said Anand Raghunathan, a Purdue Professor of Electrical and Computer Engineering, who has been working in the field for about five years. "Computers were first designed to be precise calculators that solved problems where they were expected to produce an exact numerical value. However, the demand for computing today is driven by very different applications. Mobile and embedded devices need to process richer media, and are getting smarter – understanding us, being more context-aware and having more natural user interfaces. ... The nature of these computations is different from the traditional computations where you need a precise answer."' What's interesting here is that this is how our brains work."
