The Linux Terminal Server Project has for years been simplifying the task of time-sharing a Linux system by means of X terminals (including repurposed low-end PCs). Now, stgraber writes "After almost two years or work and 994 commits later made by only 14 contributors, the LTSP team is proud to announce that the Linux Terminal Server Project released LTSP 5.2 on Wednesday the 17th of February. As the LTSP team wanted this release to be some kind of a reference point in LTSP's history, LDM (LTSP Display Manager) 2.1 and LTSPfs 0.6 were released on the same day. Packages for LTSP 5.2, LDM 2.1 and LTSPfs 0.6 are already in Ubuntu Lucid and a backport for Karmic is available. For other distributions, packages should be available very soon. And the upstream code is, as always, available on Launchpad."

quaith writes "With the Space Shuttle Endeavour scheduled to launch at 4:39 AM EST on Sunday for a trip to the International Space Station, the European Space Agency has released a video that shows how the modules it's carrying — Node-3 ('Tranquility') and Cupola — are going to get attached. Node-3 is a connecting module. Cupola has six trapezoidal windows and circular roof designed to provide a unique vantage-point for observing Earth. The video animations show how the station's robotic arm will be used initially to put the modules in place as a single unit, and then to detach Cupola from the end of Node-3 and reattach it on the Earth-facing side. With this addition, the ISS will start to look like something that Jules Verne would have wanted to visit."

snydeq writes "InfoWorld's Rick Grehen provides an in-depth comparative review of eight PHP IDEs: ActiveState's Komodo IDE, CodeLobster PHP Edition, Eclipse PHP Development Tools (PDT), MPSoftware's phpDesigner, NetBeans IDE for PHP, NuSphere's PhpED, WaterProof's PHPEdit, and Zend Studio. 'All of these PHP toolkits offer strong support for the other languages and environments (HTML, CSS, JavaScript, SQL database) that a PHP developer encounters. The key differences we discovered were in the tools they provide (HTML inspector, SQL management system) for various tasks, the quality of their documentation, and general ease-of-use,' Grehen writes.'"

silverpig writes "Yesterday marked the announcement of the Apple iPad device, and with it came a new version of the SDK. In this new version, Apple has lifted the VoIP over 3G restrictions that limited VoIP traffic to wifi only. This morning, Fring announced that its iPhone app is 3G-capable starting immediately. No update is needed as apparently the app had 3G capability all along, but a server-side block prevented its use. Furthermore, apparently a 3G-capable version of Skype has been ready for some time now, and has been waiting for this restriction to be lifted."

kylevh writes "On one side, there are the people who think that a traditional GUI—one built on windows, folders and the old desktop metaphor—is the only way to go for a tablet. In another camp, there are the ones who are dreaming about magic 3D interfaces and other experimental stuff, thinking that Apple would come up with a wondrous new interface that nobody can imagine now, one that will bring universal love, world peace and pancakes for everyone. Both camps are wrong: The iPhone started a UI revolution, and the tablet is just step two. Here's why." There are lots of cool UI ideas in there, even if it is entirely speculation. It's worth a read just to think about what the future could be like.

Hugh Pickens writes "She was at sea for 221 days, alone, often in dangerous places, and usually out of touch. Most of the time she was out of contact underwater, moving slowly up and down to depths of 600 feet, safe from ships, nets, and storms. Her predecessor had disappeared on a similar trip, probably killed by a shark. 'She was a hero,' says Rutgers University oceanographer Scott Glenn after retrieving Scarlet Knight, the 7-foot-9-inch submersible robot from the stormy Atlantic off western Spain. An engineer working for the company that made the submersible said, 'We think this will just be a precursor, like Lindbergh's trip across the Atlantic. In a decade we think it will be commonplace to have roving fleets of these gliders making transoceanic trips.' The people responsible for building, funding, and flying Scarlet hope the end of the robot's successful voyage will mark a new beginning in ocean and climate research. From its position at each surfacing — when the glider surfaced and called home via an Iridium telephone parked in its tail — researchers could calculate the net effect of currents deep and shallow. After surface currents were measured, the scientists could then make inferences about what was happening deeper in the water column. Scarlet called home to upload data to researchers three times a day. 'When we have hundreds of them, or thousands of them, it will revolutionize how we can observe the oceans,' says Jerry L. Miller, a senior policy analyst at the White House Office of Science and Technology Policy, who accompanied the research team to Spain."

necro81 writes "The NY Times is reporting on a new study from Osram, a German lighting manufacturer, which has calculated the total lifecycle energy costs of three lightbulb technologies and found that both LEDs and CFLs use approximately 20% of the energy of incandescents over their lifetimes. While it is well known that the newer lighting technologies use a fraction of the energy of incandescents to produce the same amount of light, it has not been proven whether higher manufacturing energy costs kept the new lighting from offering a net gain. The study found that the manufacturing and distribution energy costs of all lightbulb technologies are only about 2% of their total lifetime energy cost — a tiny fraction of the energy used to produce light." The study uses the assumption that LEDs last 2.5 times longer than CFLs, and 25 times longer than incandescents.

PL/SQL Guy writes "A Wisconsin appeals court ruled Thursday that police can attach GPS trackers to cars to secretly track anybody's movements without obtaining search warrants. As the law currently stands, the court said police can mount GPS on cars to track people without violating their constitutional rights — even if the drivers aren't suspects. Officers do not need to get warrants beforehand because GPS tracking does not involve a search or a seizure, wrote Madison Judge Paul Lundsten."

itif writes "This report takes a look at how many jobs you get if you invest $10 billion each in three different IT infrastructure projects — broadband, health IT and the smart grid. It argues that if you are going to be spending billions on a stimulus package, investing in 'digital infrastructure' creates more jobs than physical infrastructure (e.g. roads and bridges) in the short-term, and you get a whole host of other benefits in the long-term."

thebestsophist writes "A couple months ago, Scientists and Engineers for America, Science Debate 2008, and a bunch of other science organizations sent McCain, Obama, and all the Congressional candidates a bunch of questions on science and technology. Topics included biosecurity, genetics research, and national security, as well as the more common questions on research and education. Well, Senator Obama just answered." Senator McCain has not responded to the questionnaire at this point in time, but the site has a profile of his views and actions relating to science policy, which provides a good basis for comparing the candidates' stances. We've previously discussed the differences between the two candidates' technology platforms. According to a recent NPR story, both candidates intend to keep politics out of science.
