Submission + - Happy software developers solve problems better. (peerj.com)

Submitted by HagraBiscuit
HagraBiscuit writes: Researchers from the Faculty of Computer Science, Free University of Bozen-Bolzano, Bolzano, Italy, have quantified and analysed affective mood index against objective measures of problem-solving effectiveness for a group of software developers.
From report abstract:
"The results offer support for the claim that happy developers are indeed better problem solvers in terms of their analytical abilities. The following contributions are made by this study: (1) providing a better understanding of the impact of affective states on the creativity and analytical problem-solving capacities of developers, (2) introducing and validating psychological measurements, theories, and concepts of affective states, creativity, and analytical-problem-solving skills in empirical software engineering, and (3) raising the need for studying the human factors of software engineering by employing a multidisciplinary viewpoint."

Samsung Release First SSD With 3D NAND 85

Posted by timothy from the turning-up-the-volume dept.
Vigile (99919) writes "As SSD controllers continue to evolve, so does the world of flash memory. With the release of the Samsung 850 Pro SSD announced today, Samsung is the first company to introduce 3D NAND technology to the consumer. By using 30nm process technology that might seem dated in some applications, Samsung has been reliably able to stack lithography and essentially "tunnel holes" in the silicon while coating the inside with the material necessary to hold a charge. The VNAND being used with the Samsung 850 Pro is now 32 layers deep, and though it lowers the total capacity per die, it allows Samsung to lower manufacturer costs with more usable die per wafer. This results in more sustainable and reliable performance as well as a longer life span, allowing Samsung to offer a 10 year warranty on the new drives. PC Perspective has a full review with performance results and usage over time that shows Samsung's innovation is leading the pack."

Court Allowed NSA To Spy On All But 4 Countries 242

Posted by timothy from the under-color-of-official-right dept.
mrspoonsi (2955715) writes A court permitted the NSA to collect information about governments in 193 countries and foreign institutions like the World Bank, according to a secret document the Washington Post published Monday. The certification issued by a Foreign Intelligence Surveillance Court in 2010 shows the NSA has the authority to "intercept through U.S. companies not just the communications of its overseas targets, but any communications about its targets as well," according to the Post's report. Only four countries in the world — Britain, Canada, Australia and New Zealand — were exempt from the agreement, due to existing no-spying agreements that the Post highlights in this document about the group of countries, known as "Five Eyes" with the U.S.

stephendavion writes: WorldView-3, a commercial remote-sensing satellite intended to provide the most advanced Earth imagery, is scheduled to be launched into space in mid-August 2014. After about one year of inspection and environmental testing, Ball Corporation (BLL) has delivered the WorldView-3 satellite to a launch site at Vandenberg Air Force Base, CA. The WorldView-3, which has been built for DigitalGlobe, will be launched through United Launch Alliance Atlas 5 rocket.

Submission + - Samsung Launches First SSD With 3D Stacked NAND And It's Fast, 10 Yr. Warranty (hothardware.com)

Submitted by MojoKid
MojoKid writes: Samsung has just unveiled its latest series of solid state drives for consumer applications, the SSD 850 PRO. Like the previously-released SSD 845 EVO series, the 850 PRO leverages Samsung's tri-core MEX controller, but these new drives also feature bleeding-edge, 32 layer, 3D V-NAND flash memory that offers better power, endurance, and performance characteristics than traditional MLC NAND. Other features of the Samsung SSD 850 PRO series includes "Device sleep" (DEVSLP), which can maximize battery life in mobile devices and support for Samsung's RAPID mode technology, which leverages system RAM to boost performance. The SSD 850 series drives put up impressive numbers in a variety of benchmarks, besting many other drives in its class, but they also carry a long 10 year warranty.

Grandmother Buys Old Building In Japan And Finds 55 Classic Arcade Cabinets 133

Posted by Unknown Lamer from the treasure-trove dept.
An anonymous reader writes A grandmother agreed to purchase an old building in Chiba, which is just outside of Tokyo. When her family arrived to check out the contents of the building it was discovered that the first two floors used to be a game center in the 1980s. Whoever ran it left all the cabinets behind when it closed, and it is full of classic and now highly desirable games. In total there are 55 arcade cabinets, most of which are the upright Aero Cities cabinets, but it's the game boards that they contain that's the most exciting discovery. Boards include Donkey Kong, Street Fighter Alpha 2 (working despite the CPS2 lockout chip's tendency to kill old boards), and Metal Slug X.

Submission + - Choosing a new web language that's not too buzzy 1

Submitted by adelayde
adelayde writes: In my day job, I work on a web based service with a lot of legacy code written in that older (and some may say venerable) web-scripting language, Perl. Although we use Modern Perl extensions such as Moose the language just seems to be ossifying — http://ttfa.net/perldidntwin — and we're wanting to move to a more up-to-date and used language for web applications, or even an entire framework, to do new development. We're still planning to support the legacy code for a number of years to come; that's unavoidable.

This is a fairly big project and it's mission critical to the business. The thing we're afraid of is jumping onto something that is too new and too buzzy — http://ttfa.net/lemonmarket — as we'd like to make a technology decision that would be good at least for the next five years, if not more, and today's rising star could quite easily be in tomorrow's dustbin.

What language and/or framework would you recommend we adopt?

Submission + - Shark! New Sonar Buoy Will Warn Beachgoers When Large Sharks Are Near (gearjunkie.com)

Submitted by stephendavion
stephendavion writes: While the risk of being attacked by a shark is certainly low, it’s one of those terrors that can weigh heavy on the mind of a beach-goer, particularly in higher-risk beaches such as some in Australia and South Africa. A new device is currently being developed to warn swimmers when a shark is detected in the water near a beach, and — no surprise — the Aussies are behind it.

The Clever Buoy is being called the “world’s first shark detection buoy” by its developers. The project is a collaboration between Australian telecommunications company Optus and marine safety company Shark Attack Mitigation Systems.
