Nanospiked bacteria are the brightest hard X-ray emitters

Science Daily - Thu, 02/07/2015 - 11:36am
In a scientific breakthrough, researchers have fashioned bacteria to emit intense, hard X-ray radiation. They show that irradiating a glass slide coated with nanoparticle doped bacteria, turns the cellular material into hot, dense plasma, making this a useful table top X-ray source with several potential applications.

TracFone Finally Agrees To Allow Phone Unlocking

Slashdot - Thu, 02/07/2015 - 11:27am
jfruh writes: While most Slashdot readers probably enjoy the latest and greatest smartphones and heavy-use data plans, millions of Americans use low-cost, prepaid featurephones, and many of those are sold under various brand names owned by TracFone. Today, after much pressure from the FCC, TracFone admitted that its customers also have the right to an unlocked phone that they can port to a different provider, including those low-income customers who participate in the government-subsidized Lifeline program, widely (though incorrectly) known as "Obamaphone".

SlideN'Joy Extender Adds Up To Two More Screens For a Multi-Monitor Laptop

Slashdot - Thu, 02/07/2015 - 9:35am
MojoKid writes: Nothing beats the portability of a notebook when it comes to getting work done while on-the-go, but with that portability comes a number of caveats like a smaller keyboard and being forced to use a touchpad if you don't want to lug around a portable mouse. Then there's also the limitation of a single display, for those who need more screen real estate for certain tasks. Enter Sliden'Joy, a Kickstarter project that's set to launch on July 6. There's not a lot of technical detail given about it so far, but the basics are easy to understand. Sliden'Joy effectively hooks onto your notebook to allow you to extend one or two screens out of either side, giving you an effective dual or triple monitor setup. Two models of Sliden'Joy are going to be produced, offering either 1 or 2 displays, and sizes of 13, 15, and 17-inch are all going to be supported. There's no word on pledge levels quite yet, but the ultimate goal is to reach 300,000€ ($~332,000 USD) in 30 days.

Retro City Rampage Getting a DOS Version

Slashdot - Thu, 02/07/2015 - 7:01am
jones_supa writes: There is an indie game port in works which certainly cracks a smile on one's face. Vblank Entertainment is bringing Retro City Rampage — its homage to 8-bit games and Grand Theft Auto — over to one of the influential gaming operating systems of all time: DOS! Retro City Rampage 486 is a port of Retro City Rampage DX, an enhanced version of the game featuring a story mode, arcade challenges, and free roaming. As the name suggests, if one wants to run the game natively, a beefy 486 CPU is required, along with 3.7 MB of disk space and 4 MB of RAM. But of course, DOSBox can be used as well. A release date for the DOS version of the game is not yet known.

Exploring the Relationships Between Tech Skills (Visualization)

Slashdot - Thu, 02/07/2015 - 4:30am
Nerval's Lobster writes: Simon Hughes, Dice's Chief Data Scientist, has put together an experimental visualization that explores how tech skills relate to one another. In the visualization, every circle or node represents a particular skill; colors designate communities that coalesce around skills. Try clicking "Java", for example, and notice how many other skills accompany it (a high-degree node, as graph theory would call it). As a popular skill, it appears to be present in many communities: Big Data, Oracle Database, System Administration, Automation/Testing, and (of course) Web and Software Development. You may or may not agree with some relationships, but keep in mind, it was all generated in an automatic way by computer code, untouched by a human. Building it started with Gephi, an open-source network analysis and visualization software package, by importing a pair-wise comma-separated list of skills and their similarity scores (as Simon describes in his article) and running a number of analyses: Force Atlas layout to draw a force-directed graph, Avg. Path Length to calculate the Betweenness Centrality that determines the size of a node, and finally Modularity to detect communities of skills (again, color-coded in the visualization). The graph was then exported as an XML graph file (GEXF) and converted to JSON format with two sets of elements: Nodes and Links. "We would love to hear your feedback and questions," Simon says.
