You Can Now Buy This Tiny Computer for $35

29 Feb

Last year, we have experienced a lot to get excited about over the tiny computer, the Raspberry Pi.  It can stream video via Airplay, can run Quake III. Inspite of these  features the device costs just $35. Fortunate enough, now you can buy it.

The Model B Raspberry Pi is just now finishing its production in China. People can pre-order it now. It runs on an ARM11 processor, 256MB of RAM, 2 USB ports, a LAN port, an SD card slot, audio-out and HDMI-out. It’s capable of running an Ubuntu install or a version of Xbox Media Center, but nothing comes pre-installed so one will be spending some time at a command line.

But the rattling bit is: it costs $35. Thirty. Five. Freakin’. Dollars. This device is unbelievably cheap, and a great way to get you—or your kids—into coding. In fact, the beauty of the Raspberry Pi business model is that all the profits will be pushed into a charity set up to encourage kids to get into coding, an initiative which will itself use these tiny computers.

You can buy Raspberry Pi online from Premier Farnell or RS Components. [Raspberry Pi]

Microsoft Designs Bluetooth Keyboard for Tablets

21 Dec

This keyboard is designed to be used with Apple’s two iPad tablets, numerous Android devices and Microsoft Windows.

Keen eyes have discovered that Microsoft has raised a count in its library of gadgets with a new keyboard. Simply called the Bluetooth Mobile Keyboard 5000, it’s compatible with Microsoft Windows, Apple’s iPad and iPad 2, and “many Android devices.” It measures just 0.62-inches in depth, making it nearly twice as thick as Apple’s flagship device.

“Miss the tactile feeling of a real keyboard when typing on your tablet? The full-sized Bluetooth Mobile Keyboard 5000 enables more comfortable typing than on-screen keyboards, and encourages natural posture with the Comfort Curve design,” says the product description. “And at less than three-quarters of an inch thick, you can easily slip it into your bag, which makes it the perfect mobile companion. Plus, there’s no need to worry about cords or transceivers.”

Microsoft’s big selling point is not only in the tablet-friendly Bluetooth connection, but the keyboard’s  shape with “comfort curve” design that “encourages natural wrist posture and is easy to use.” This does not need an USB-based Bluetooth adapter. Except this features, it will be just another Bluetooth keyboard that works on three AAA alkaline batteries and requires a PC enabled with Bluetooth technology.

It’s probably no coincidence that we’re seeing this tablet-oriented keyboard show up right before CES 2012. Windows 8 tablets are planned to launch not before the fall, but this does not stands as an obstacle  for Microsoft from getting ready while offering a branded product for competing devices in the process.

Microsoft’s Bluetooth Mobile Keyboard 5000 is offered now for $49.95 and can be purchased directly from the company here.

Intel Scheduling 22 nm Ivy Bridge for April 2012

28 Nov

Following a report that AMD is scrapping the production of its 28 nm processor at GlobalFoundries, there is a note that Intel may also be delaying at least some of its 22 nm processors due to manufacturing hiccups.

Since the introduction of its tick-tock balanced, rhythmic beat back in 2005, Intel traditionally launched a new generation of die shrinks at the end of uneven years, but the 45 nm and 32 nm products appeared to be squeezed into those years, while the actual volume rollout occurred several months later. The reports that 22 nm Core i3000 processors won’t make it into 2011. Instead, Intel’s Ivy Bridge platform is likely to debut around April 2012. Intel’s (32 nm) Xeon E5 is delayed to spring 2012 as well.

There is no information about the reason of the possible delays. Last week, a report suggested that AMD is also dealing with some manufacturing problems.

Fujitsu Launches 23 PFlops PRIMEHPC FX10 Supercomputer

28 Nov

Fujitsu has begun offering a new supercomputer, which the company claims can be scaled to a performance of up to 23.2 PFlops, which would make it the fastest system on the Top500 list and even exceed the upcoming BlueGene/Q-based Sequoia system.

To accomplish this performance, the computer will be configured with a total of 1024 racks integrating a total of 98,304 computing nodes and 6 PB of memory. The base configuration has four racks with 384 processors.

The announcement seems to more interesting with the fact that PRIMEHPC FX10 will be using the SPARC64 IFfx  processor, the successor chip to the SPARC64 VIIIfx, which is currently used in the world’s fastest supercomputer, K Computer system, in Japan. But, however, the SPARC64 IXfx  integrates 16 cores, instead of eight cores. This indicates that Fufitsu’s 23.2 PFlops supercomputer would boast a stunning 1,572,864 processing cores – more than twice the number of cores in the K Computer’s 705,024.

As stated by Fujitsu, a single SPARC64 IXfx processor will deliver a floating point performance of 236.5 GFlops, about 85 percent more than the SPARC64 VIIIfx, which tops out at 128 GFlops. The company said that the computation efficiency is at about 2 GFlops per watt, which indicates that individual processors will run at about 115 watt at 1.85 GHz.

In comparison, IBM will use a 16-core PowerPC A2 processor in the 20 PFlops Sequoia system which will be installed at the Lawrence Livermore National Laboratory (LLNL) in 2012. IBM said that its A2 processor will consume only 30 watts; however, since the company states that the 98,304 computing nodes A2 system will reach just about 20 Flops, we would assume that the A2 is not quite as powerful as the SPARC64 IXfx.

Yikes! New Computer System Can Read Your Emotions

28 Nov

Researchers from the Universidad Carlos III de Madrid has developed an emotion-reading AI.

It’s bad enough your significant other insists that there’s something wrong when there really isn’t, but now it looks as if we’ll be dealing with an emotion-reading AI in the not-too-distant. But don’t get too frightened just yet: we may still be a ways off from talking to HAL 9000 and listening to him/it cheering us up first thing in the morning with a little tune if we seem a little down in the dumps. 

The study was published in the Journal on Advances in Signal Processing. As explained in their study, the computer system created by these researchers independently adapts its dialogue to the users’ situation so that its responses are on the same page as the users’ emotional state. The system uses up to 60 different types of acoustic parameters including tone of voice, speed of speech, duration of pauses and even the energy of the voice signal. Significantly, it looks for negative emotions like anger, boredom and doubt.

When the emotion is detected, the system then finds out the user’s overall intention in a given dialogue. A news release by the Universidad Carlos III de Madrid states an example.

For example, if the system did not correctly recognize what the interlocutor wanted to say several times, or if it asked the user to repeat information that s/he had already given, these factors could anger or bore the user when s/he was interacting with the system. Moreover, the authors of the study point out that it is important that the machine be able to predict how the rest of the dialogue is going to continue.

The researchers solved the problem by developing a statistical method that uses earlier dialogues to learn what actions the user is most likely to take at any given moment. Once the system has detected the user’s intention — along with his/her emotional state — it automatically adapts the dialogue to the situation the user is experiencing. The report reads,

For example, if s/he has doubts, more detailed help can be offered, whereas if s/he is bored, such an offer could be counterproductive. The authors defined the guidelines for obtaining this adaptation by carrying out an empirical evaluation with actual users; in this way they were able to demonstrate that an adaptable system works better in objective terms (for example, it produces shorter and more successful dialogues) and it was perceived as being more useful by the users.

There is no doubt, if this AI goes commercial, we might as well kiss human tech support — whether it’s local or based overseas.
