New submitter Isaac-1 writes "First it was the sex offenders being mapped using public records, now it seems to be gun owners — I wonder who will be next? It seems a newspaper in New York has published an interactive map with the names and addresses of people with [handguns]." It's happened before: In 2007, Virginia's Roanoke Times raised the ire of many gun owners by publishing a database of Virginia's gun permit holders that it assembled based on public records inquiries. (The paper later withdrew that database.) Similarly, WRAL-TV in North Carolina published a database earlier this year with searchable map of (partially redacted) information about permit holders in that state, and Philadelphia made the news for a similar disclosure — complete with interactive map and addresses — of hundreds of gun permit applicants and holders.

An anonymous reader writes "Here is a free interactive beta of Learn Linux The Hard Way; a web-based virtual Linux environment which introduces the command line and other essential Linux concepts in 30 exercises. It's written in the style of Zed A. Shaw's Learn Code the Hard Way lessons. The authors says, 'You will encounter many detailed tables containing lists of many fields. You may think you do not need most of this information, but what I am trying to do here is to teach you the right way to approach all this scary data. And this right way is to interpret this data as mathematical formulas, where every single symbol has its meaning.' Of course, my first entry was rm -rf /* which only produced a stream of errors. I wish I had discovered something like a long time ago."

MrSeb writes "If you've gone shopping for a power supply any time over the last few years, you've probably noticed the explosive proliferation of various 80 Plus ratings. As initially conceived, an 80 Plus certification was a way for PSU manufacturers to validate that their power supply units were at least 80% efficient at 25%, 50%, 75%, and 100% of full load. In the pre-80 Plus days, PSU prices normally clustered around a given wattage output. The advent of the various 80 Plus levels has created a second variable that can have a significant impact on unit price. This leads us to three important questions: How much power can you save by moving to a higher-efficiency supply, what's the premium of doing so, and how long does it take to make back your initial investment?"

First time accepted submitter iggymanz writes "More precise modeling has changed some long term climate predictions: sea levels to rise almost a meter more than present over the next century, but past dire warnings of stronger storms or more frequent droughts won't pan out. Instead there will be less strong storms, but peak winds in the tropics might be slightly higher. Temperature rise of global average will be about 3 degree C total, including the 1 degree C rise over the 20th century. In places where precipitation is frequent, it will become even more frequent; in arid areas, the tendency will be to become even drier. Some new arid areas are expected to appear in the south of N. America, South Africa and Mediterranean countries. Overall, hardly a doomsday scenario."

nk497 writes "Dell's 'Project Sputnik' laptop is now on sale. The XPS 13 Developer Edition comes with Ubuntu 12.04 pre-installed, and costs $1,549 — $50 more than the same model running Windows. The Ubuntu Ultrabook is the result of a skunkworks project to optimise the open-source OS to run on Dell projects, to create better laptops for developers. The idea of the project was to create a laptop for developers, based around 'the idea that developers are the kings of IT and set the agenda for web companies, who in turn, set the agenda for the whole industry,' Dell said." Reader skade88 points out a positive review from Ars Technica.

iONiUM writes "From the article: 'Over the years at the U.N. climate talks, the goal has been to keep future global warming below 2C. But as those talks have faltered, emissions have kept rising, and that 2C goal is now looking increasingly out of reach. Lately, the conversation has shifted toward how to deal with 3C of warming. Or 4C. Or potentially more." Overall it seems that poorer, less developed nations will be largely impacted negatively, while some countries (like Canada and Russia) will actually experience benefits. Where does that leave the rest of the 1st world countries?"

bshell writes "Canada's CRTC (like the FCC) has finally asked telecoms to provide information about how much their services actually cost. Quoting a Montreal Gazette story: 'In a report I wrote last year, I estimated the markup for Internet services was 6,452 per cent for Bell's Essential Plus plan, which provides a two-megabits-per-second speed for $28.95 (prices may have changed since last year).' The markup is likely similar in the U.S. It's about time that we consumers found out what it really costs to provide Internet service, and for that matter telephone and wireless services, so we can get a fair shake."

Ollabelle writes "David Bernstein, a nonprofit executive who lives in Gaithersburg, Md., has two sons, ages 7 and 15. He has previously written about how schools fail students with Attention Deficit Hyperactivity Disorder. Now he turns his attention to mandated curriculum in public schools, and argues that his sons shouldn't be forced to take any science class." From the article: "There’s a concept in economics called 'opportunity costs,' which you may not have learned about because you were taking chemistry instead of economics. Opportunity costs are the sacrifices we make when we choose one alternative over another. ... When you force my son to take chemistry (and several other subjects, this is not only about chemistry), you are not allowing him that same time to take a public speaking course, which he could be really good at, or music, or political science, or creative writing, or HTML coding for websites."

concealment sends this quote from an article at CNN: "Moderating a discussion on the future of broadband, Mashable editor-in-chief Lance Ulanoff tossed a provocative question to the audience: 'By quick show of hands, how many out there think that broadband is a luxury?' Next question: 'How many out there think it is a human right?' That option easily carried the audience vote. Broadband access is too important to society to be relegated to a small, privileged portion of the world population, Hans Vestberg, president and CEO of Ericsson, said during the discussion. Dr. Hamadoun Touré, secretary-general of the International Telecommunication Union, echoed Vestberg's remarks. 'We need to make sure all the world's inhabitants are connected to the goodies of the online world, which means better health care, better education, more sustainable economic and social development,' Touré said."
