NVIDIA Pitches GPU Computing in the Cloud

, , , ...

At the Web 2.0 Summit in San Francisco recently, NVIDIA announced a GPU-powered 3D Web platform. Called the NVIDIA RealityServer, it consists of Tesla GPUs, rendering software and a Web service environment, all integrated into a platform designed to deliver photorealistic image streams via a cloud computing model. The new offering is yet another example of how the company intends to push its high-end GPUs into CPU territory.

The basic idea behind RealityServer is to do all the heavy computation lifting of image rendering on the server side, such that photorealistic 3D content can be delivered interactively across the Web. That means mass-market devices from smart phones to desktops and everything in between can be used to do high-end imaging.

Applications include architectural design, product design, manufacturing and apparel styling, as well as HPC visual applications in such areas as oil and gas, medical diagnostics, and scientific research. As a result, potential users span the entire population: consumers, artists, product designers, doctors, architects, engineers, and scientists.

Mining the Web for Feelings, Not Facts

, , ,

Computers may be good at crunching numbers, but can they crunch feelings?

The rise of blogs and social networks has fueled a bull market in personal opinion: reviews, ratings, recommendations and other forms of online expression. For computer scientists, this fast-growing mountain of data is opening a tantalizing window onto the collective consciousness of Internet users.

An emerging field known as sentiment analysis is taking shape around one of the computer world’s unexplored frontiers: translating the vagaries of human emotion into hard data.

This is more than just an interesting programming exercise. For many businesses, online opinion has turned into a kind of virtual currency that can make or break a product in the marketplace.
Yet many companies struggle to make sense of the caterwaul of complaints and compliments that now swirl around their products online.

As sentiment analysis tools begin to take shape, they could not only help businesses improve their bottom lines, but also eventually transform the experience of searching for information online.

Global IP Traffic to Increase Fivefold by 2013

, , , ...

Cisco announced the results of the Cisco® Visual Networking Index (VNI) Forecast and Methodology, 2008-2013 that confirms consumer broadband usage and global IP network traffic continues to climb at an overwhelming pace due to new forms and expanded usage of interactive media, and the explosion of video content across multiple devices. The study projects that global IP traffic will increase fivefold by 2013. There are key consumer and service provider implications to the forecast that compares regions around the globe including North America, Western Europe, AsiaPac, Middle East and more.

Global IP traffic is expected to increase fivefold from 2008 to 2013, approaching 56 exabytes per month in 2013, up from approximately 9 exabytes per month in 2008.

By 2013, annual global IP traffic will reach two-thirds of a zettabyte (or 667 exabytes). (A zettabyte is a trillion gigabytes.)

Beware surfers: cyberspace is filling up

, , ,

Internet users face regular “brownouts” that will freeze their computers as capacity runs out in cyberspace, according to research to be published later this year.

Experts predict that consumer demand, already growing at 60 per cent a year, will start to exceed supply from as early as next year because of more people working online and the soaring popularity of bandwidth-hungry websites such as YouTube and services such as the BBC’s iPlayer.

It will initially lead to computers being disrupted and going offline for several minutes at a time. From 2012, however, PCs and laptops are likely to operate at a much reduced speed, rendering the internet an “unreliable toy”.

A 3D web moves closer to reality

, , , ...

The 3D web moved closer to reality as Mozilla, the developer of the Firefox browser, joined forces with graphics consortium Khronos. Khronos has set up a working group to create a standard for what it calls accelerated 3D graphics on the web.

It could lead to widespread browser-based gaming as well as creating 3D environments in social networking sites such as Facebook and MySpace.

The aim is to produce a first public version within a year.

"For a number of reasons, I think now is the time to .. figure out what an initial take of 3D on the web should look like," said Mozilla's infrastructure engineer Vladimir Vukicevic in his blog.

"People are doing more and more on the web… adding 3D to this mix ensures that current web applications can experiment with new user experiences, while also enabling new classes of web applications," he said.

Hadoop, a Free Software Program, Finds Uses Beyond Search

, , , ...

In the span of just a couple of years, Hadoop, a free software program named after a toy elephant, has taken over some of the world’s biggest Web sites. It controls the top search engines and determines the ads displayed next to the results. It decides what people see on Yahoo’s homepage and finds long-lost friends on Facebook.

It has achieved this by making it easier and cheaper than ever to analyze and access the unprecedented volumes of data churned out by the Internet. By mapping information spread across thousands of cheap computers and by creating an easier means for writing analytical queries, engineers no longer have to solve a grand computer science challenge every time they want to dig into data. Instead, they simply ask a question.

“It’s a breakthrough,” said Mark Seager, head of advanced computing at the Lawrence Livermore National Laboratory. “I think this type of technology will solve a whole new class of problems and open new services.”

Experts uncover weakness in Internet security

, , ,

Independent security researchers in California and researchers at the Centrum Wiskunde & Informatica (CWI) in the Netherlands, EPFL in Switzerland, and Eindhoven University of Technology (TU/e) in the Netherlands have found a weakness in the Internet digital certificate infrastructure that allows attackers to forge certificates that are fully trusted by all commonly used web browsers.

As a result of this weakness it is possible to impersonate secure websites and email servers and to perform virtually undetectable phishing attacks, implying that visiting secure websites is not as safe as it should be and is believed to be. By presenting their results at the 25C3 security congress in Berlin on the 30th of December, the experts hope to increase the adoption of more secure cryptographic standards on the Internet and therewith increase the safety of the internet,

Safer than ActiveX: a look at Google's Native Client plugin

, , , ...

Google has released a new experimental browser plugin that allows web applications to securely run native code on the underlying platform. The plugin, which is called Native Client, is distributed under the open source BSD license and is designed to work with all major platforms and browsers.

Allowing web applications to run native code has traditionally posed significant security risks. Microsoft's COM-based ActiveX technology, which aimed to provide developers with similar capabilities, is widely viewed as one of the most egregious security failings of the Windows operating system and it has become a frequent attack vector for malicious code.

Google believes that its security model has the potential to be far more robust and effective than the code-signing system of trust used by ActiveX. Google's engineers explain the differences between the Native Client and ActiveX security models in a paper about the project:

Infovell's 'research engine' finds deep Web pages that Google, Yahoo miss

, ,

According to a study by the University of California at Berkeley, traditional search engines such as Google and Yahoo index only about 0.2% of the Internet. The remaining 99.8%, known as the "deep Web," is a vast body of public and subscription-based information that traditional search engines can't access.

To dig into this "invisible" information, scientists have developed a new search engine called Infovell geared at helping researchers find often obscure data in the deep Web. As scientists working on the Human Genome Project, Infovell´s founders designed the new searching technology based on methods in genomics research. Instead of using keywords, Infovell accepts much longer search terms, and in any language.

Mozilla Weave 0.2 puts Firefox in the cloud

, , ,

Mozilla Labs has announced the availability of Weave 0.2, the third major release of its experimental Firefox synchronization add-on. This version brings a broader feature set, improved reliability, and streamlined notification support. Although it is still in the early testing stage, Weave is already effective and easy to use.

When Mozilla launched Weave in December, the add-on offered basic support for storing the user's Firefox bookmarks and history in the cloud, allowing the synchronization of the data between computers. The latest version extends this functionality to also cover cookies, passwords, tabs, and form contents. Future versions will go further and also support synchronizing the user's extensions, themes, and search plugins. Mozilla intends to eventually implement an API that will enable third-party Firefox extensions to leverage Weave's synchronization capabilities for other kinds of user data.
