Submission + - Creating a Battery Smaller Than a Grain of Salt (gizmag.com)

Zothecula writes: As development of micro- and nano-scale devices continues to advance, so does the need for an equally-tiny method of powering them. There’s not much point in developing a surveillance micro air vehicle the size of a housefly, for instance, if it requires a watch battery in order to fly. That’s why DARPA (the U.S. Defense Advanced Research Projects Agency) is funding a project to create really tiny batteries. Just how tiny are we talking, here? Well, they’re aiming for something smaller than a grain of salt.

Google Introduces Command-Line Tool For Linux 210

Lomegor writes "'Ever wanted to upload a folder full of photos to Picasa from a command prompt?' Google introduced today a new project, Google CL, that lets you do that and much more. It's a new command line tool for Linux that acts as an interface with Google services; you can upload videos to YouTube or maybe post a new blog post in Blogger in just one line."

Submission + - Could cow manure power your data centre? (itpro.co.uk)

nk497 writes: HP will today present a paper outlining a plan to power data centres with cow manure. Essentially, the animal waste and heat from the data centre will be combined to produce methane, which will then power the data centre. HP Labs figures a farm of 10,000 dairy cows will be enough to power one mid-sized data centre, helping out the environment by using up pollutants and creating a sustainable energy source but also giving farmers an additional income stream — as much as $2 million a year.

Using Augmented Reality To Treat Cockroach Phobia Screenshot-sm 126

RichDiesal writes "In this blog post, I describe a new use for augmented reality — treating people for cockroach phobia. A recent paper in the academic journal Cyberpsychology, Behavior and Social Networking discusses a system where people suffering from cockroach phobia sit at a desk with a virtual reality headset. The headset has a camera on the front so that patients see the desk they're sitting at — but covered in cockroaches. In the study, researchers managed to elicit a fear response to virtual cockroaches similar to what would be experienced with real cockroaches. Sounds like a little slice of hell to me."

Steam Client for Mac Launches, Linux Client On the Way 572

CyDharttha writes with news that the Mac version of Steam went live today, along with Mac versions of Portal, Team Fortress 2, and many other games. Valve plans to make more games available every Wednesday. Several publications are also reporting that a Linux version of Steam has been confirmed, and is expected within the next few months. Quoting Phoronix: "Found already within the Steam store are Linux-native games like Unreal Tournament 2004, World of Goo, and titles from id Software such as Enemy Territory: Quake Wars and Doom 3. Now that the Source Engine is officially supported on Linux, some Source-based games will be coming over too. Will we finally see Unreal Tournament 3 surface on Linux too? Only time will tell, but it is something we speculated back in 2008. Postal III is also being released this year atop the Source Engine and it will be offering up a native client. We have confirmed that Valve's latest and popular titles like Half-Life 2, Counter-Strike: Source, and Team Fortress 2 are among the first of the Steam Linux titles, similar to the Mac OS X support. The released Linux client should be available by the end of summer."

Why Computer Science Students Cheat 694

alphadogg writes "Enrollment in undergraduate computer science courses is at an all-time high at colleges nationwide. But this trend that's been hailed by the US tech industry has a dark side: a disproportionate number of students taking these courses are caught cheating. More students are caught cheating in introductory computer science courses than in any other course on campus, thanks to automated tools that professors use to detect unauthorized code reuse, excessive collaboration, and other forbidden ways of completing homework assignments. Computer science professors say their students are not more dishonest than students in other fields; they're just more likely to get caught because software is available to check for plagiarism. 'The truth is that on every campus, a large proportion of the reported cases of academic dishonesty come from introductory computer science courses, and the reason is totally obvious: we use automated tools to detect plagiarism,' explains Professor Ed Lazowska, chair of computer science and engineering at the University of Washington. 'We compare against other student submissions, and we compare against previous student submissions and against code that may be on the Web. These tools flag suspicious cases, which are then manually examined.'"

Submission + - Fedora presents...Graphics Test Week this week

AdamWill writes: The Fedora project announces that this week is Graphics Test Week. Tuesday April 13th is NVIDIA Test Day, Wednesday April 14th is ATI/AMD Test Day, and Thursday April 15th is Intel graphics Test Day. Even if you're not a Fedora user, you can help Linux as a whole by contributing your test results. The testing can be done using a live image, so there's no need to install Fedora onto your system to contribute to the testing: just download a live image, write it to a CD or USB stick, boot it, and run through the tests. Comprehensive test instructions are available on the Wiki pages, and you enter your results into a table on the Wiki page; there's no need to have a Fedora wiki account to do this. QA team members and developers will be available on the IRC channels throughout each event to help with testing and triage, and to work on some of the problems immediately. If you have time, please check out the Wiki pages and join the IRC channel — #fedora-test-day on the Freenode network — to help out! You can use WebIRC if you're not a regular IRC user — just click that link and you're in the chat.
