How Big US Firms Use Open Source Software 116

Diomidis Spinellis writes "We hear a lot about the adoption of open source software, but when I was asked to provide hard evidence there was little I could find. In a recent article we tried to fill this gap by examining the type of software the U.S. Fortune 1000 companies use in their web-facing operations. Our study shows that the adoption of OSS in large U.S. companies is significant and is increasing over time through a low-churn transition, advancing from applications to platforms, and influenced by network effects. The adoption is likelier in larger organizations and is associated with IT and knowledge-intensive work, operating efficiencies, and less productive employees. Yet, the results were not what I was expecting."

Researchers May Have Discovered How Memories Are Encoded In the Brain 185

Zothecula writes "While it's generally accepted that memories are stored somewhere, somehow in our brains, the exact process has never been entirely understood. Strengthened synaptic connections between neurons definitely have something to do with it, although the synaptic membranes involved are constantly degrading and being replaced – this seems to be somewhat at odds with the fact that some memories can last for a person's lifetime. Now, a team of scientists believe that they may have figured out what's going on. Their findings could have huge implications for the treatment of diseases such as Alzheimer's."

DoD Networks Completely Compromised, Experts Say 164

AZA43 writes "A group of U.S. federal cybersecurity experts recently said the Defense Department's network is totally compromised by foreign spies. The experts suggest the agency simply accept that its networks are compromised and will probably remain that way, then come up with a way to protect data on infected machines and networks."

Blackjack Player Breaks the Bank At Atlantic City 294

Hugh Pickens writes with a link to Atlantic writer Mark Bowden's account of how one gambler has cleaned up against casinos: "[B]lackjack player Don Johnson won nearly $6 million playing blackjack in one night, single-handedly decimating the monthly revenue of Atlantic City's Tropicana casino after previously taking the Borgata for $5 million and Caesars for $4 million. How did Johnson do it? For one thing, Johnson is an extraordinarily skilled blackjack player. 'He plays perfect cards,' says Tony Rodio. But that's not enough to beat the house edge. As good as Johnson is at playing cards, his advantage is that he's even better at playing the casinos. When revenues slump as they have for the last five years at Atlantic City, casinos must rely more heavily on their most prized customers, the high rollers who wager huge amounts and are willing to lessen its edge for them primarily by offering discounts, or 'loss rebates.' When a casino offers a discount of, say, 10 percent, that means if the player loses $100,000 at the blackjack table, he has to pay only $90,000."

Entrepreneurs Watch As Crowdvesting Bill Stalls In Senate 182

cayenne8 writes "The JOBS Act bill, passed in the house, has stalled in the senate. One section of this bill, which would legalize 'Crowdsourcing' in the U.S., as it is in other countries, allowing companies and startups (like indie film makers) to solicit investments for profit over the internet. This differs from sites like Kickstarter, which allow you to only donate money, in that this bill will allow the common citizen to invest for potential profit ($10K or 10% of income for investor limits) in new ideas and companies."

Aspirin Helps Prevent Cancer, New Studies Show 132

kkleiner writes "For years, research has shown that aspirin is beneficial in preventing heart attacks. Now new studies support its ability to prevent cancer as well. The studies, involving tens of thousands of participants over many decades, show reductions of cancer incidence (both short- and long-term) and mortality rate as well as a decrease in metastatic cancer. It still is not known exactly how aspirin and cancer are connected, but those between the ages of 45-50 will now likely consider taking low-dose aspirin daily for the remainder of their lives."

Nvidia's Fermi Architecture Debuts; Nouveau Driver Already Working 70

crookedvulture writes Nvidia has lifted the curtain on reviews of its latest GPU architecture, which will be available first in the high-end GeForce GTX 680 graphics card. The underlying GK104 processor is much smaller than the equivalent AMD GPU, with fewer transistors, a narrower path to memory, and greatly simplified control logic that relies more heavily on Nvidia's compiler software. Despite the modest chip, Nvidia's new architecture is efficient enough that The Tech Report, PC Perspective, and AnandTech all found the GeForce GTX 680's gaming performance to be largely comparable to AMD's fastest Radeon, which costs $50 more. The GTX 680 also offers other notable perks, like a PCI Express 3.0 interface, dynamic clock scaling, new video encoding tech, and a smarter vsync mechanism. It's rather power-efficient, too, but the decision to focus on graphics workloads means the chip won't be as good a fit for Nvidia's compute-centric Tesla products. A bigger GPU based on the Kepler architecture is expected to serve that market." Read on below for good news (at least if you prefer Free software) from an anonymous reader. Update: 03/22 19:35 GMT by T : Mea culpa -- that headline should say "Kepler," rather than Fermi; HT to Dave from Hot Hardware (here's HH's take on the new GPU).

Judge Rules Pi-Based Music Is Non-Copyrightable 183

New submitter AnalogDiehard writes "A copyright case alleging infringement of a 1992 Lars Erickson song 'The Pi Symphony' by Michael John Blake's 'What Pi Sounds Like' was dismissed by U.S. District Court Judge Michael H. Simon. Both pieces were conceived by assigning numbers to musical notes, then deriving a melody based on the pattern defined by a finite set of numbers in Pi. Judge Simon wrote in his legal opinion, intentionally announced on Pi day (3/14), that 'Pi is a non-copyrightable fact.' While the Judge did not invalidate the Erickson copyright, he ruled that 'Mr. Erickson may not use his copyright to stop others from employing this particular pattern of musical notes.' The judge further ruled that the two pieces were not sufficiently similar — for instance, its harmonies, structure and cadence are all different."

Verizon Says Hactivists Now Biggest Corporate Net Threat 150

alphadogg writes "Hactivists — not cybercriminals — were responsible for the majority of personal data stolen from corporate and government networks during 2011, according to a new report from Verizon. The Verizon 2012 Data Breach Investigation Report found that 58% of data stolen in 2011 was the result of hactivism, which involves computer break-ins for political rather than commercial gain. In previous years, most hacking was carried out by criminals, Verizon said. Altogether, Verizon examined 855 cybersecurity incidents worldwide that involved 174 million compromised records. This is the largest data set that Verizon has ever examined, thanks to its cooperation with law enforcement groups including the U.S. Secret Service, the Dutch National High Tech Crime Unit and police forces from Australia, Ireland and London."

Ask MIT Researchers About Fusion Power 318

Nuclear fusion power is the process of fusing light nuclei together to release energy, and ultimately, to put electricity on the grid. Today, we have six researchers from MIT's Plasma Science and Fusion Center here to answer your questions about fusion power, tokamaks, and public support and funding in the U.S. for this research. The Obama Administration's budget request for fiscal year 2013 is paying for the U.S. share of ITER construction out of the domestic program, starting with the closure of the MIT fusion lab. The interviewees are ready to answer technical and policy questions, so don't be shy! And, as always, please break unrelated questions into separate posts. Read on for information about the researchers who will answer your questions.

Apple vs. Nokia, RIM and Motorola On Nano-SIM Standard 144

angry tapir writes "Next week, two proposals for a new, smaller SIM card, dubbed nano-SIM — one backed by Apple and the other by Nokia, Research In Motion and Motorola Mobility — will go head-to-head as ETSI (the European Telecommunications Standards Institute) decides which card future smartphones and tablets will use. Measuring approximately 12 millimeters by 9 millimeters, the new SIM will be about 30 percent smaller than the micro-SIM. The thickness of the cards has been reduced by about 15 percent, according to Giesecke & Devrient. The nano-SIM is also approximately 60 percent smaller than traditional-size SIM cards."

Amiga Returns With Lackluster Linux-Powered Mini PC 343

crookedvulture writes "Commodore has revealed the Amiga mini, a small-form-factor system that runs a custom Linux distro dubbed Commodore OS Vision. A trailer for the OS hardly inspires confidence, and the rest of the system doesn't help. While the Amiga mini features a high-end Intel desktop CPU and modern conveniences like Blu-ray, USB 3.0, and 802.11n Wi-Fi, it's stuck with one of the slowest graphics chips Nvidia makes. Some of the other specifications are head-scratchers, too. The mini comes with a whopping 16GB of RAM but only a terabyte of storage. You'll have to pay extra to get an SSD, which makes the $2500 asking price particularly onerous. The case, Blu-ray drive, and power supply are being made available separately, but at $345, they're hardly a bargain. Add this to the list of nostalgia-baiting remakes that don't live up to their inspiration." Update: It looks like Commodore has dropped the price after receiving a lot of negative feedback.
