miller60 writes "Saying 1,100 data centers is too many, the federal government has begun what looms as the largest IT consolidation in history. Federal CIO Vivek Kundra has directed federal agencies to inventory their assets by April 30 and prepare a plan to reduce the number of servers and data centers, with a focus on slashing energy costs (full memo). Kundra says some applications may be shifted to cloud computing platforms customized for government use."

Several sources are reporting on the new offering from the British firm Pelikon which combines a touchpad and morphing keyboard into a unique little device. "This isn't just any old morphing keyboard, you see. Not only can the board be dynamically reconfigured by backlighting different portions of the keys — the entire surface of the thing doubles as a touchpad, which you can probably imagine has virtually limitless utility in a mobile device where the space for a true touchpad simply doesn't exist. Pelikon already works with Toshiba on its domestic-market Biblio, but we'd love to see it hit devices around the world — in fact, we wouldn't really mind if they just released this prototype they're showing as a Bluetooth accessory. diNovo Mini competitor, anyone?"

angry tapir writes with news that Google Go seems to be cutting a wide swath through the programming community in just a short time since its early, experimental release. While Google insists that Go is still a work in progress (like so many of their offerings), many developers are so intrigued by the feature set that they are already implementing many noncritical applications with it. What experiences, good or bad, have you had with Google Go, and how likely is it to really take over?

suraj.sun writes to tell us that Engadget got an early look at the new Windows Phone 7 series early prototype (and included a video). "The QWERTY slider is the first branded Windows Phone 7 Series device the world's ever seen, and while the hardware and software are both obviously early, we can tell you a few things about it: it's just a hair thicker than an iPhone or Nexus One, there are dedicated hardware camera, volume, and power buttons in addition to the back, home, and search buttons dictated by Windows Phone 7 Series, and we noticed a five megapixel camera with a flash on the back, along with a headphone jack. Can't say much apart from that right now, since things are so early and everything is subject to change, but things are certainly moving along."

A BOFH writes "The longer I do desktop support, the more it becomes obvious that my users don't read anything that appears on their screen. Instead, they memorize a series of buttons to press to get whatever result they want and if anything unexpected happens, they're completely lost. Error logs help a lot, but they have their limits. I've been toying with a few ideas, but I don't know if any of them will work and I was hoping my fellow Slashdotters could point me in the right direction. For example, I was thinking about creating icons or logos to identify specific errors. They might not remember that an error is about 'uninitialized data' but they might be more able to remember that they got the 'puppy error' if I showed a puppy picture next to the error message. Or for times when finding images is too time consuming, you could create simple logos from letters, numbers, symbols, colors, or shapes, so you could have the 'red 5' error or 'blue square' error (or any combination of those elements). I've even wondered if it would be possible to expand that to cover the other senses, for example, playing a unique sound with the error. Unfortunately, haptic and olfactory feedback aren't readily available. I like to think that my users would remember the error that caused them to get a swift kick in the balls. And if they forgot it anyhow, I could always help them reproduce it. Does anyone else have experience with ideas like these? Did it work?"

roh2cool writes "If you are a watch freak and also happen to be a fan of ultra rare (and expensive) gadgets, this might just interest you. The LG GD910 watch phone looks like a normal watch – except for the fact that it can double up as your mobile phone when needed. 'It is quite thin at just 13.9mm and packs in 3G and Video Calling capabilities as well. The phone is quite stylish and the front fascia is covered by scratch-proof tempered glass. It comes with a Bluetooth headset so you don’t have to keep talking like David Hasselhoff talked to his super-car KITT in the “Knight Rider” series.'"

Physicist Sean Carroll has built up a bit of a name for himself by tackling one of the age old questions that no one has been able to fully explain: What is time? Earlier this month he gave an interview with Wired where he tried to explain his theories in layman's terms. "I’m trying to understand how time works. And that’s a huge question that has lots of different aspects to it. A lot of them go back to Einstein and spacetime and how we measure time using clocks. But the particular aspect of time that I’m interested in is the arrow of time: the fact that the past is different from the future. We remember the past but we don’t remember the future. There are irreversible processes. There are things that happen, like you turn an egg into an omelet, but you can’t turn an omelet into an egg."

MojoKid writes "Hard drive capacities are sometimes broken down by the number of platters and the size of each. The first 1TB drives, for example, used five 200GB platters; current-generation 1TB drives use two 500GB platters. These values, however, only refer to the accessible storage capacity, not the total size of the platter itself. Invisible to the end-user, additional capacity is used to store positional information and for ECC. The latest Advanced Format hard drive technology changes a hard drive's sector size from 512 bytes to 4096 bytes. This allows the ECC data to be stored more efficiently. Advanced Format drives emulate a 512 byte sector size, to keep backwards compatibility intact, by mapping eight logical 512 byte sectors to a single physical sector. Unfortunately, this creates a problem for Windows XP users. The good news is, Western Digital has already solved the problem and HotHardware offers some insight into the technology and how it performs."

daedae writes "It seems Facebook has been granted a patent for the news feed, as a method of monitoring activities, storing them in a database, and displaying an appropriate set of activities to an appropriate set of users. 'That sounds pretty broad, and the social-networking world was all atwitter at the possible ramifications. Writing for ReadWriteWeb, Marshall Kirkpatrick proclaimed, "This could be very big. ... MySpace, Flickr, Yahoo, Twitter (?), the sharing part of Google Reader, and even Google Buzz — do all of these sites have technology at the center of their social experiences that falls under this new patent of Facebook's?" The patent may not be that broad. Nick O'Neill at the All Facebook blog wrote that the patent doesn't appear to cover status updates as used by Twitter. "It appears that this patent surrounds implicit actions. This means status updates, which is what Twitter is based on, are not part of this patent. ... Instead, this is about stories about the actions of a user's friends. While still significant, the implications for competing social networks may be less substantial," O'Neill wrote.'"

Several sources are reporting on a new metric that computer scientists are going after with respect to recommender systems — recommendation diversity. "In a paper that will be released by PNAS, a group of scientists are pushing the limits of recommendation systems, creating new algorithms that will make more tangential recommendations to users, which can help expand their interests, which will increase the longevity and utility of the recommendation system itself. Accuracy has long been the most prized measurement in recommending content, like movies, links, or music. However, computer scientists note that this type of system can narrow the field of interest for each user the more it is used. Improved accuracy can result in a strong filtering based on a user's interests, until the system can only recommend a small subset of all the content it has to offer."

KentuckyFC writes writes to share a new online test that is being touted as the "financial Turing test." The web-based exercise asks users to distinguish between real and randomly generated financial data. "Various economists argue that the efficiency of a market ought to be clearly evident in the returns it produces. They say that the more efficient it is, the more random its returns will be and a perfect market should be completely random. That would appear to give the lie to the widespread belief that humans are unable to tell the difference between financial market returns and, say, a sequence of coin tosses. However, there is good evidence that financial markets are not random (although they do not appear to be predictable either). Now a group of scientists have developed a financial Turing test to find out whether humans can distinguish real financial data from the same data randomly rearranged. Anybody can take the test and the results indicate that humans are actually rather good at this kind of pattern recognition."

An anonymous reader writes to share recent statements by Chinese scientists that indicate troubled waters ahead if Google were to pull out of China. "More than three-quarters of scientists in China use the search engine Google as a primary research tool and say their work would be significantly hampered if they were to lose it, a survey showed on Wednesday. In the survey, 84 percent said losing Google would 'somewhat or significantly' hamper their research and 78 percent said international collaborations would be affected. 'Research without Google would be like life without electricity,' one Chinese scientist said in the survey, which asked more than 700 scientists for their views."
