writes Data and Goliath: The Hidden Battles to Collect Your Data and Control Your World, author Bruce Schneier could have justifiably written an angry diatribe full of vitriol against President Obama and the NSA for their wholesale spying on innocent Americans and violations of myriad laws. Instead, he was written a thoroughly convincing and brilliant book about big data, mass surveillance and the ensuing privacy dangers facing everyone. A comment like what's the big deal? often indicates a naiveté about a serious significant underlying issue. The idea that if you have nothing to hide you have nothing to fear is a dangerously narrow concept on the value of privacy. For many people the notion that the NSA was performing spying on Americans was perceived as not being a big deal, since if a person is innocent, then what do they have to worry about. In the book, Schneier debunks that myth and many others, and defends the importance of privacy.

sends word that hot dry winters may be the norm in the future for California. "Climate change is one of the most prominent public health issues currently on the CDC's radar. The organization's Climate and Health Program attempts to help state and city health departments to prepare for the health impacts of climate change, which can come in the form of things like temperature extremes, air pollution, allergens, and changes in disease patterns; they can also be felt indirectly through issues like food security. Since 2012, California has been in the midst of a record-setting drought, with extremely warm and dry conditions characterizing the last three years in that state. A new paper published in the Proceedings of the National Academy of Sciences concludes that warming caused by humans is responsible for the conditions that have led to this California drought. This study, published by scientists affiliated with the Department of Environmental Earth System Science and the Woods Institute for Environment at Stanford University, used historical statewide data for observed temperature, precipitation, and drought in California. The investigators used the Palmer Hydrological Drought Index (PHDI) and the Palmer Drought Severity Index (PDSI), collected by the National Climatic Data Center, as measures of the severity of wet/dry anomalies. They also used global climate model simulations from the Coupled Model Intercomparison Project (CMIP) to compare historical predictions for anthropogenic and non-anthropogenic historical climates."Read Replies (0)

writes It took about 50,000 CPU hours and 4PB of disk IO, but now we know the exact number of legal 18x18 Go positions. Seeking computing power for the ultimate 19x19 count.
And it's not a heat-death-of-the-universe kind of question, either, they say: "Thanks to the Chinese Remainder Theorem, the work of computing L(19,19) can be split up into 9 jobs that each compute 64 bits of the 566-bit result. Allowing for some redundancy, we need from 10 to 13 servers, each with at least 8 cores, 512GB RAM, and ample disk space (10-15TB), running for about 5-9 months."Read Replies (0)
