Epson to Ship Lowest-Priced 1080p Projector Yet

epson_front_PowerLite.jpgWe just got the scoop from Epson: the company says it will indeed deliver that new-and-improved 1080p projector that we told you about earlier today to the United States this December. It will be called the Epson PowerLite Home Cinema 1080 UB, and most startling of all is its price: $2699, a full $300 less than its predecessor and the lowest price yet for a 1080p projector. That's full 1080p, 50,000:1 contrast ratio and 1600 lumens. Take the jump for the full fact sheet scoop, ship date and a gallery of pics.



Calvin College duo creates cheap, portable supercomputer

Just months after scientists were able to run a quantum computer simulation on an everyday PC, we're now hearing that a Calvin College student / professor tandem have created an inexpensive, portable supercomputer for crunching massive chunks of data on the go (and on the cheap). Dubbed Microwulf, the wee beast is hailed as a "machine that is among the smallest and least expensive supercomputers on the planet," and when not being checked as baggage on a flight, can reportedly process 26.25 gigaflops of data per second. The system itself touts "four dual-core motherboards connected by an eight-port gigabit Ethernet switch," and when initially constructed, it cost just $2,470 to build. Talk about a solid price-to-performance ratio. [Via Slashdot] Student, prof build budget supercomputer August 30 , 2007

Tim Brom stands next to supercomputer MicrowulfWhen Tim Brom 07’ set out to build a budget supercomputer with Calvin computer science professor Joel Adams, he didn’t know the product of his efforts might end up in his checked baggage headed for England.

Brom, now a graduate student at the University of Kentucky continuing his studies in computer science, worked with Adams to build Microwulf, a machine that is among the smallest and least expensive supercomputers on the planet.

“It’s small enough to check on an airplane or fit next to a desk,” said Brom.

This may prove useful next summer when Brom and others from his graduate program travel to England to do work that will require “a significant amount of computing power.” And as the price of commercial supercomputers is often prohibitive for many educational institutions, bringing a “personal” supercomputer like Microwulf could be a cost-effective solution for the group of graduate researchers.

“So far as we can tell, this is the first supercomputer to have this low price/performance ratio—the first to cost less than $100/Gflop,” said Adams.

This is a significant achievement considering that Microwulf is more than twice as fast as Deep Blue, the IBM-created supercomputer that beat world chess champion Gary Kasparov in 1997, and cost only a fraction of the $5 million spent to build Deep Blue.

Microwulf has been measured to process 26.25 gigaflops, or 26.25 billion double-precision floating point instructions, per second. It achieves this performance by relying on four dual-core motherboards connected by an 8-port Gigabyt Ethernet switch. The connected components form a three-tiered system that looks like a triple-decker sandwich.

Design of supercomputer Microwulf

Supercomputers like Microwulf are used to solve problems that take too much number-crunching for an ordinary desktop to handle, either because its processor is too slow, or because it doesn’t have enough memory, said Adams. Truly huge supercomputers (more than 100 times as fast as Microwulf) are used by organizations like the National Weather Service to process meteorological data and by the United States Missile Defense Agency to simulate nuclear tests.

Microwulf is considered a Beowulf cluster, a group of networked computers that run open source software and work in parallel to solve a single problem. Beowulf clusters are so named because their homemade, cost-effective nature liberates researchers from expensive commercial options for super-computing, much like Beowulf of the Old English poem liberated the Danes from the tyrannical rule of Grendel.

Do Brom and Adams see themselves as “liberators” by unveiling of a system like Microwulf?

“We’re taking the liberation a step further,” said Adams. “Instead of a bunch of researchers having to share a single Beowulf cluster supercomputer, now each researcher can have their own.”

Just two years ago, building a personal supercomputer like Microwulf for the price of a high-performance desktop was out of the realm of possibility for Adams and Brom. But when they saw a portable Beowulf cluster called Little Fe at a conference in October 2005, they began to think about building their system.

“I was really enjoying my high-performance computing class and wanted to keep working in that area after the class ended. I was also thinking about graduate school at the time and a project like Microwulf looks good on a curriculum vitae,” said Brom.

So by the summer of 2006 when the price of hardware materials needed to build Microwulf had gone down, Adams asked his academic department to provide $2500 for the project. He also asked Brom, then beginning his last year at Calvin, to help him build the supercomputer. In January of 2007, they began to piece together their system and by March, they were running tests to see just what Microwulf could do. In the end, the project came in under budget with Microwulf donning a price-tag of just $2470. With current hardware prices, another system like Microwulf would cost half of what it cost Adams and Brom to build earlier this year.

Though supercomputers are typically evaluated on their price/performance ratio, Adams built Microwulf giving attention to its power/performance ratio as well. In other words, he wanted to pay attention to the system’s energy consumption.

“This is becoming increasingly important, as excess power consumption is inefficient and generates waste heat, which can in turn decrease reliability,” said Adams on his Web site.

Adams and Brom managed to build Microwulf so that it could plug into one standard 120V wall outlet. This feature only enhances the system’s portability, allowing it to be taken to classrooms and other research labs where large power supplies are unavailable.

Adams isn’t going to let Microwulf gather dust in the supercomputing lab in the Science Building. Instead he’s going to take it out on the road, mostly to middle school and high school classrooms to try and get teenagers hooked on computer science.

Microwulf’s inventors aren’t set on keeping their blueprints for the supercomputer a secret. In fact, they’ve just published a detailed description and evaluation of their project on Cluster Monkey so others can build their own portable and affordable supercomputers.

It remains to be seen whether Brom will be able to get his wire-filled personal supercomputer past airport security next summer.

UK comes together on mobile micropayments

Carriers in the UK have started to roll out PayForIt, an industry-standard solution for micropayments -- charges totaling less than £10 (about $20.16) in this case -- to their subscribers. Though there are already plenty of ways to pay for odds and ends likes games and ringtones through cellphones, that in itself is a problem; with payment services like premium-rate text messages, customers are left with a confusing experience that leave them wary of the whole process and less likely to use it again. PayForIt, on the other hand, leaves buyers with a standard receipt page regardless of what they're purchasing along with some semblance of assurance that the system is secure. Purchases show up on the next month's phone bill, at which point purchasing 650 ringtones may seem like a distinctly poorer plan (not to say we've ever done that or anything). No word on when we might see the service outside the British Isles; companies involved over there seem to be pretty amped, though, so if everything pans out, we imagine a broader launch will be in the cards.


Epson eats their own, launches TW2000 1080p 3LCD projector

Here it is, Epson's latest 3LCD projector to take advantage of their new 0.74-inch HTPS panels already spotted in Mitsubishi and Sanyo projectors. The EMP-TW2000 starts with a trio of Epson-built, 0.74-inch, 1,920 x 1,080 C2FINE LCD panels with D7 process technology, 12-bit LCD driver, and updated OptiFocus engine with DeepBlack phase compensation technology. They then bust a rated 50,000:1 dynamic contrast at 1,600 lumens off a 170W UHE (E-TORL) bulb while supporting x.v.Color over a pair of HDMI v1.3 inputs -- component, S-Video, and D-Sub 15 PC input sprinkled in for fun. Nicely done Epson. Yours in Japan later this month for about ¥350,000. That'll be a tax-inclusive $3,020 when it comes Stateside under the PowerLite Pro Cinema branding. Pics of the backside, front and huge-ass, plastic remote control after the break.


Google Flight Simulator Easter Egg


If you were thinking, "Those guys at Google are going to pack in a secret flight simulator into the new edition of Google Earth," pat yourself on the back, as that is exactly what they have done.Apparently, the latest version of Google Earth has an easter egg: a flight simulator. It's not quite like Microsoft Flight Simulator, but it's a promising start. How to see this feature. Make sure you have Google Earth 4.2. Open the application, click on the globe and then press Ctrl+Alt+A. You should see this dialog that lets you choose one of the two aircrafts (F16 "Viper" and SR22) and an airport. Here's the initial view from London Heathrow Airport: ... and here's a nice view from Kathmandu: To fly, you need to read this list of keyboard shortcuts, but you can also use a mouse or a joystick. "To disable or enable mouse controls, left click (single click on a Mac). Once mouse controls are active, the pointer shape changes to a cross on your screen." Marco Gallotta, who found this feature, has some tricks: "Moving on though, you can get a quick start by holding Page Up for a few seconds to increase to maximum thrust (thrust meter is the left bar of the lower-left meters). Once you've accelerated to a sufficient velocity use the arrow keys to take-off. The keys are in reverse as one would expect with any flight simulator, so use the down arrow to take-off. When you've gained enough altitude then stabalise the aircraft to a straight flight path. It can be rather tricky to get the hang of as the controls are quite sensitive." This easter egg could become a standard feature in the next versions of Google Earth and it will bring even more fun to the application.
