clipper's remarks: Back in 1998/99, myself and a co-worker were brainstorming on computing ideas. We came up with an idea for a computer screen that would act like a kiosk of sorts, for the elderly. Realizing that there was a need to keep in touch and up to date with technology, it 'felt right' to bring something like touch screen for the elderly or those that could not type, into age (pun intended). Our idea was to set up these kiosk style monitors in senior assisted/non-assisted homes; on campus clubhouses, etc so anyone could send email and play a few games. Easy stuff that would not be intimidating or difficult to learn.

Idea blown away when presented to our employer as not 'marketable enough.'

About 3 weeks ago, I walked into Sam's Club; the computer section. A round table was set up with HP Touchscreen monitors. Curios, I walked over to inspect and could not get close enough except to watch. Persons much older than myself standing around the table, playing games by touching the scre

Windows 7: Inside Multitouch

what makes Windows 7 so exciting is that no computer operating system ever incorporated native support for multitouch before. The new breed of multitouch laptops and desktops with touch screens don't need extra downloads or plugins-- multitouch just works

Vista offered single-touch capabilities in tablet mode, and pen input is quite common as well. But as much as Microsoft would love to paint multitouch as a natural progression in its operating systems, its Apple that was the real democratizer of multiple-input touch screens.

Optical sensors are set up around the screen creating a grid. The screen reacts when your finger, pen, stylus, or any other implement break one of the beams

pen, stylus, or any other implement break one of the beams; you don't actually have to physically touch the surface to get a response.

there's no question that this interface can change the way we look at computing.

Oracle grid update tied to emerging cloud middleware trend

Oracle this week shipped an update to its Coherence in-memory data grid, a member of a class of middleware that some say may be on the cusp of broader adoption for cloud computing.In-memory data grids store information that applications need in memory across a pool of servers, instead of reading it off disks, resulting in major performance gains.The Coherence product is one of the more mature in a market occupied by offerings from IBM as well as smaller companies like GigaSpaces and a number of open-source projects. Microsoft is also developing a system dubbed "Velocity."To date, such systems have breathed rarefied air, mostly supporting large-scale Web sites and high-throughput transactional systems, such as stock trading applications.

Cloud Computing pundits have predicted that the early adopters will be largely comprised of small and mid-sized businesses.

Some new data from Forrester suggests that won't be the case.

one out of four large companies plan to use an external provider soon, or have already employed one. Furthermore, we learn that 33 per cent of large companies plan to use a service provider for Infrastructure-as-a-Service, while just 24 per cent want to run their own "private" clouds.

cloud computing brings a disruptive and liberating pricing model to infrastructure. Why sink capital costs into infrastructure when you don't have to?

Enterprise hosting companies are already positioned to deliver cloud computing services to the enterprise market,

IT hosting is in the process of transforming to electric-utility-like status. We will think of IT hosters as providing IT infrastructure as a service, and we will want to "plug in" to these providers as we plug in to the power grid today.

Briefing: Cloud Computing

According to its advocates, cloud computing is poised to succeed where so many other attempts to deliver on-demand computing to anyone with a network connection have failed. Some skepticism is warranted. The history of the computer industry is littered with the remains of previous aspirants to this holy grail, from the time-sharing utilities envisioned in the 1960s and 1970s to the network computers of the 1990s (simple computers acting as graphical clients for software running on central servers) to the commercial grid systems of more recent years (aimed at turning clusters of servers into high-performance computers). But cloud computing draws strength from forces that could propel it beyond the ranks of the also-rans.

Honey Bee

Why is it some bees can be queen? How can a nurse bee suddenly transform into a forager, just when foragers are needed most? And how can these furry flying insects cast light on our own human behaviors?

The answers lie in the interactions of genes in the honey bee genome. And Saurabh Sinha needs grid computing to seek these answers out.

“The honey bee can be a model to understand complex societies,” explains Sinha, a professor of computer science and affiliate of the University of Illinois’s Institute for Genomic Biology.

“By studying the social regulation of gene expression, we hope to extrapolate the biology to humans.”

“It’s not as if a particular honey bee behavior is exactly mapped in humans,” he says. “But, if we can discover some general principles for the genetic basis of social behavior, we hope they will largely carry forward to human behavior.”

Ancient Instrument Revived by Computing

Reviving Ancient Sounds | Listen to the computerized version of the instrument here.

March 17, 2009 -- Powerful grid computing has revived a stringed musical instrument that was last played in ancient Greece, Italian researchers announced at a recent conference in Catania, Sicily.

Called an epigonion after the 6th century B.C. musician Epigonus of Ambracia, the instrument was somewhat similar to a modern harp.

No complete example of an epigonion has survived, yet it is known the instrument had 40 strings of varying lengths and a soundboard, like a guitar. Its strings were plucked with fingers.

Ancient Greek Homes Doubled as Pubs

Using data from various sources, including images in artwork, fragments from excavations and written descriptions, researchers of the Ancient Instruments Sound/Timbre Reconstruction Application, or ASTRA, project succeeded in developing a 3D mechanical computer model of the instrument.

Binary waves from black holes.

If you're a PlayStation 3 fan, or if you just received one as a holiday gift, you may be able to do more with the system than just gaming. A group of gravity researchers have configured 16 PlayStation 3's together to create a type of supercomputer that is helping them estimate properties of the gravitational waves produced by the merger of two black holes.

calls their configuration the Gravity Grid, and they say the Sony PlayStation 3 has a number of unique features that make it particularly suited for scientific computation. Equally important, the raw computing power per dollar provided by the PS3 is significantly higher than anything else on the market today.

The PlayStation 3 cluster used by the gravity research team can solve some astrophysical problems, such as ones involving many calculations but low memory usage, equaling the speed of a rented super-computer.

A hundred years ago, companies stopped generating their own power with steam engines and dynamos and plugged into the newly built electric grid. The cheap power pumped out by electric utilities didn’t just change how businesses operate. It set off a chain reaction of economic and social transformations that brought the modern world into existence. Today, a similar revolution is under way. Hooked up to the Internet’s global computing grid, massive information-processing plants have begun pumping data and software code into our homes and businesses. This time, it’s computing that’s turning into a utility.

LHC Grid: Data storage and analysis for the largest scientific instrument on the planet

The Large Hadron Collider (LHC) is a particle accelerator that aims to revolutionize our understanding of our universe. The Worldwide LHC Computing Grid (LCG) project provides data storage and analysis infrastructure for the entire high energy physics community that will use the LHC.

The LCG, which was launched in 2003, aims to integrate thousands of computers in hundreds of data centers worldwide into a global computing resource to store and analyze the huge amounts of data that the LHC will collect. The LHC is estimated to produce roughly 15 petabytes (15 million gigabytes) of data annually. This is the equivalent of filling more than 1.7 million dual-layer DVDs a year! Thousands of scientists around the world want to access and analyze this data, so CERN is collaborating with institutions in 33 different countries to operate the LCG.

clipper's remarks: The Grid is coming

Clip Source: technology.timesonline.co.uk

A network of 100,000 computers providing the greatest data processing capacity yet unleashed has been created to cope with information pouring from the world’s largest machine.

The Grid is the latest evolution of the internet and the world wide web and computer scientists will announce on Friday that it is ready to be connected to the Large Hadron Collider (LHC).

It is designed for schemes where huge quantities of data need crunching, such as large research and engineering projects. The Grid has the kind of power required to download movies in seconds, and the ability to make high-definition video phone calls for the same price as a local call. More importantly, it should help to narrow the search for cures for diseases. However, it is unlikely to be directly available to most internet users until telecoms providers build the fibre-optic network required to use it.

Global computer network behind the Big Bang probe

GENEVA (AP) — The world's biggest physics experiment, the Large Hadron particle collider that began running Wednesday in a 17-mile tunnel below the French-Swiss border, produces so much data that even the massive computing power at the European Organization for Nuclear Research can't sift through it all.

So the Geneva-based lab, known by its old French acronym CERN, is sharing that burden among dozens of computing centers around the world. The result is the LHC Grid, a network of 60,000 computers that will analyze what happens when protons are hurled at each other inside the collider.

Scientists will need the additional computing power to sift through the mountains of data produced when the colliders' four giant detectors — 10 times more accurate than any previous instruments — measure activity at the subatomic level.
