First time accepted submitter ASDFnz writes "The reward for successfully completing a block (also called mining) is about to halve from 50 bitcoins to 25. From the article: 'Bitcoin is built so that this reward is halved every 210,000 blocks solved. The idea is as bitcoin grows the transaction fees become the main part of the reward and the introduction of new bitcoins slows down to a trickle. This also means that there will only ever be 21,000,000 bitcoins in circulation.' You can watch the countdown here."

A study has found that a decreased pH level in the antarctic is damaging the shells of native wildlife. "Marine snails in seas around Antarctica are being affected by ocean acidification, scientists have found. An international team of researchers found that the snails' shells are being corroded. Experts says the findings are significant for predicting the future impact of ocean acidification on marine life. The results of the study are published in the journal Nature Geoscience (abstract). The marine snails, called "pteropods", are an important link in the oceanic food chain as well as a good indicator of ecosystem health. 'They are a major grazer of phytoplankton and... a key prey item of a number of higher predators - larger plankton, fish, seabirds, whales,' said Dr Geraint Tarling, Head of Ocean Ecosystems at the British Antarctic Survey and co-author of the report."
An anonymous reader writes "We've heard this one before, over and over again: pirates are the biggest spenders. It therefore shouldn't surprise too many people to learn that shutting down Megaupload earlier this year had a negative effect on box office revenues. The latest finding comes from a paper titled: 'Piracy and Movie Revenues: Evidence from Megaupload.'"
An anonymous reader sends this excerpt from The Hill: "The past week's violence in Gaza has rekindled calls for Twitter to shutter the accounts of U.S.-labeled terror groups such as Hamas. Seven House Republicans asked the FBI in September to demand that Twitter take down the accounts of U.S.-designated terrorist groups, such as Hamas, Hezbollah and Somalia's al Shabaab. The letter to FBI Director Robert Mueller was spearheaded by Rep. Ted Poe (R-Texas), who said Wednesday that the recent events vindicated the request. 'Allowing foreign terrorist organizations like Hamas to operate on Twitter is enabling the enemy,' [Poe said] 'Failure to block access arms them with the ability to freely spread their violent propaganda and mobilize in their War on Israel.'"
An anonymous reader writes "The amusing 'but does it run Crysis?' question has a cousin: 'but does it run Minecraft?' The makers of Raspberry Pi can now officially say that yes, yes it does. Called Minecraft: Pi Edition, the latest flavor of the popular game carries 'a revised feature set' and 'support for several programming languages,' so you can code directly into Minecraft before or after you start playing. That means you can build structures in the traditional Minecraft way, but you can also break open the code and use a programming language to manipulate things in the game world."
David Hume writes "The Los Angeles Times has a story about the two-year University of Tulsa Cyber Corps Program. About '85% of the 260 graduates since 2003 have gone to the NSA, which students call "the fraternity," or the CIA, which they call "the sorority."' 'Other graduates have taken positions with the FBI, NASA and the Department of Homeland Security.' According to the University of Tulsa website, two programs — the National Science Foundation's Federal Cyber Service: Scholarship for Service and the Department of Defense's (DOD's) Information Assurance Scholarship Program — provide scholarships to Cyber Corps students."
dncsky1530 writes "UNSW professor Richard Buckland, lecturer of the famous Computing 1 course on YouTube, is now running a large scale open online Computer Science course for the world. UNSW Computing 1 — PuzzleQuest and the Art of Programming starts off with microprocessors and works it way through C with interactive activities while taking students on an adventure of hacking, cracking and problem solving. It's based around a three month long PuzzleQuest with grand and suspiciously unspecified prizes as well as fame and glory for the intrepid. The next class starts December 3rd 2012."

Unfortunately, British cryptographers at the country's Government Communications Headquarters (GCHQ) have been unable to crack the code encrypting a message the bird was tasked with sending and say they are confident it cannot be decoded 'without access to the original cryptographic material.'"

From the article: 'Could browser ad blocking one day become so prevalent that it jeopardises potentially billions of dollars of online ad revenue, and the primary business models of many online and new media businesses? If so, it will inevitably face legal attack.'"

It was built from open source kit and cheap hardware by a security penetration tester who wanted to make his love of wardriving more nimble. The plans are detailed in a diagram and a video."
An anonymous reader writes with an update about the student refusing to wear an RFID badge in Texas. From the article: "A district court judge for Bexar County has granted a temporary restraining order (TRO) to ensure that Andrea Hernandez, a San Antonio high school student from John Jay High School's Science and Engineering Academy, can continue her studies pending an upcoming trial. The Northside Independent School District (NISD) in Texas recently informed the sophomore student that she would be suspended for refusing to wear a 'Smart' Student ID card embedded with a Radio Frequency Identification (RFID) tracking chip."
Hugh Pickens writes "Richard Anderson reports on BBC that despite stringent carbon emissions targets in Europe designed to slow global warming and massive investment in renewable energy in China, coal, the dirtiest and most polluting of all the major fossil fuels, is making a comeback with production up 6% over 2010, twice the rate of increase of gas and more than four times that of oil. 'What is going on is a shift from nuclear power to coal and from gas to coal; this is the worst thing you could do, from a climate change perspective,' says Dieter Helm. Why the shift back to coal? Because coal is cheap, and getting cheaper all the time. Due to the economic downturn, there has been a 'collapse in industrial demand for energy,' leading to an oversupply of coal, pushing the price down. Meanwhile China leads the world in coal production and consumption. It mines over 3 billion tons of coal a year, three times more than the next-biggest producer (America), and last year overtook Japan to become the world's biggest coal importer. Although China is spending massive amounts of money on a renewable energy but even this will not be able to keep up with demand, meaning fossil fuels will continue to make up the majority of the overall energy mix for the foreseeable future and when it comes to fossil fuels, coal is the easy winner — it is generally easier and cheaper to mine, and easier to transport using existing infrastructure such as roads and rail, than oil or gas. While China is currently running half a dozen carbon capture and storage (CCS) projects — which aim to capture CO2 emissions from coal plants and bury it underground — the technology is nowhere near commercial viability. 'Renewed urgency in developing CCS globally, alongside greater strides in increasing renewable energy capacity, is desperately needed,' writes Anderson, 'but Europe's increasing reliance on coal without capturing emissions is undermining its status as a leader in clean energy, and therefore global efforts to reduce CO2 emissions.'"
hypnosec writes "Plans for 64-bit Firefox for Windows have been put on hold by Mozilla in a bid to concentrate more on the 32-bit version. Eliminating the 64-bit nightly builds was proposed by Benjamin Smedberg, a Firefox developer, last week. Some of the reasons Smedberg cited include missing plugins for 64-bit version; lack of windowproc hooking which facilitates smooth functioning of whatever plugins are available; and the inability to work on the crash reports submitted for the 64-bit versions because they were not on high priority. The proposal, it seems, has been accepted as is evident from this bug report." The bug tracking system seems unable to differentiate between 64-bit and 32-bit builds, causing a few issues since Windows 64-bit builds are much buggier. They also intend to reintroduce 64-bit Windows nightlies some time next year.
CowboyRobot writes with the (not unexpected) official U.S. denial of using the Flame malware to spy on France. From the article: "That allegation was leveled at the U.S. government by unnamed French officials, according to a Tuesday report in the weekly French newspaper L'Express. It reported that computers belonging to top advisers to then French president Nicolas Sarkozy had been hacked using the Flame cyberespionage malware, which was designed to be used in highly targeted attacks... Napolitano was also asked if it wasn't ironic that while the United States has been sounding alarms over the growing amount of malware that's targeting U.S. government system, it also commissioning the Stuxnet and Flame cyber-espionage malware used against Iran. Napolitano, however, pled official ignorance. 'These programs were never attributed in any way to the U.S. government.'"
daria42 writes "Looks like Google's habit of funneling billions of dollars in revenue through its Irish and Bermuda subsidiaries continues to attract unfavorable government attention globally. France has already announced plans to take on the search giant's tax evasion habits, and the Australian Government, to which Google paid just $74,000 in tax last year despite having Australian revenues close to $1 billion, has now confirmed plans to do the same."
