Submission + - AMD Kaveri Notebook APU Preview Shows Solid All Around Performance (hothardware.com)

MojoKid writes: AMD has had a tough time competing with Intel on the desktop lately, but when it comes to the notebook arena, performance, value and power efficiency are measured against a very different yardstick. Multimedia performance in these highly integrated designs can matter much more than desktop designs where discrete graphics engines are easily accommodated. Back in January of this year, AMD launched their Kaveri desktop APU. Targeted for desktops and with integrated AMD GCN graphics on board, Kaveri also had a number of optimizations and enhancements made to its Steamroller CPU cores as well. All told, Kaveri represents a much-needed upgrade to AMD's base APU lineup. Today, AMD is launching their Kaveri mobile variant and early testing shows it's relatively competitive versus mainstream Intel notebook chips, even the latest Haswell cores. With four AMD Steamroller CPU cores and up to 8 GCN-based GPU cores on board, AMD's Kaveri mobile APUs offer up competitive CPU performance and graphics performance that surpasses Intel's integrated graphics by a wide margin, with the exception of perhaps their rare, high-end Iris Pro variant.

Submission + - NASA Begins Testing of New Spectrograph on Agency's Airborne Observatory (nasa.gov)

stephendavion writes: Astronomers are eagerly waiting to begin use of a new instrument to study celestial objects: a high-resolution, mid-infrared spectrograph mounted on NASA's Stratospheric Observatory for Infrared Astronomy (SOFIA), the world's largest flying telescope. This new instrument, the Echelon-Cross-Echelle Spectrograph (EXES), can separate wavelengths of light to a precision of one part in 100,000. At the core of EXES is an approximately 3-foot (1 meter) bar of aluminum called an echelon grating, carefully machined to act as 130 separate mirrors that split light from the telescope into an infrared "rainbow." SOFIA is a heavily modified Boeing 747 Special Performance jetliner that carries a telescope with an effective diameter of about 8-feet (2.5-meters) at altitudes of 39,000 to 45,000 feet (12 to 14 km), above more than 99 percent of Earth's atmospheric water vapor. Lower in the atmosphere, at altitudes associated with most ground-based observatories, water vapor obscures much of what can be learned when viewed in the infrared spectrum.

Submission + - Facebook rushes to encrypt data centre links (itnews.com.au)

littlekorea writes: Facebook's security engineering chief has promised the social network is 'aggressively' working to encrypt links between its data centers, following moves by Google to do the same. Revelations by former US intelligence contractor turned whistleblower Edward Snowden that the NSA was able to tap data center links was incidental, he told journalists today, but "proved we were wearing our tin hats correctly."

Submission + - Linux Mint 17 "Qiana" released (linuxmint.com)

Tailhook writes: Linux Mint 17 "Qiana", a long term support edition of Linux Mint, has been released. Mint 17 is available in both MATE and Cinnamon editions. Mint 17 is derived from Ubuntu 14.04 (Trusty Tahr) and will receive security updates until April, 2019. The Cinnamon edition provides Cinnamon 2.2, with a much improved update manager, driver manager, HiDPI display support and many usability refinements. This release of Mint establishes a baseline on which the next several releases will be based; `Until 2016 the development team won't start working on a new base and will be fully focused on this one; future versions of Linux Mint will use the same package base as Linux Mint 17, making it trivial for people to upgrade.'

Submission + - Bitcoin Securities Issuer Settles with SEC (thedrinkingrecord.com)

MrBingoBoingo writes: The United States Securities and Exchange Commission has extracted a Settlement from Erik Voorhees that consists of $15,843.98 in profits and a penalty of $35,000 for the high crime of having been involved in financing two offerings with Bitcoin. If you read the Security and Exchange Commission's actual filing you can see that all of the fines and settlements relate to FeedZeBirds with any actions relating to S.DICE on MPEx consisting of a strong finger wag and stern look. With the light assessment in this case, it seems that the SEC's ability to act in mature Bitcoin markets like MPEx may be limited unless they work to build cooperative relationships with those markets.

Submission + - AMD, Nvidia, and developers weigh in on GameWorks controversy (extremetech.com)

Dputiger writes: Since Nvidia debuted its GameWorks libraries there's been allegations that they unfairly disadvantaged AMD users or prevented developers from optimizing code. We've taken these questions to developers themselves and asked them to weigh in on how games get optimized, why Nvidia built this program, and whether its an attempt to harm AMD customers.

Comment Hey kids! (Score 1) 253

By all means, let's keep kids from exploring science in an interesting way. I made a Van DeGraff generator in HS for a science project that would draw a one foot spark and light up flourescent tubes in the ceiling in the 70's as a way of exploring static electricity. I'm sure today it wouldn't be allowed in a science fair. Safety culture has become so oppressive that many kids just avoid science and technology altogether. If you haven't shocked yourself silly messing around by High School, you're a wimp.
