Searching the Web could become faster for users and much more efficient for search companies if search engines were split up and distributed around the world, according to researchers at Yahoo. 

Currently, search engines are based on a centralized model, explains Ricardo Baeza-Yates, a researcher at Yahoo's Labs in Barcelona, Spain. This means that a search engine's index--the core database that lists the location and relative importance of information stored across the Web--as well as additional data, such as cached copies of content, are replicated within several data centers at different locations. The tendency among search companies, says Baeza-Yates, has been to operate a relatively small number of very large data centers across the globe.

Baeza-Yates and his colleagues devised another way: a "distributed" approach, with both the search index and the additional data spread out over a larger number of smaller data centers. With this approach, smaller data centers would contain locally relevant information and a small proportion of globally replicated data. Many search queries common to a particular area could be answered using the content stored in a local data center, while other queries would be passed on to different data centers.

"Many people have talked about this in the past," says Baeza-Yates. But there was resistance, he says, because many assumed that such an approach would be too slow or expensive. It was also unclear how to ensure that each query got the best global result and not just the best that the local center had to offer. A few start-up companies have even launched peer-to-peer search engines that harness the power of users' own machines. But this approach hasn't proven very scalable.

To achieve a workable distributed system, Baeza-Yates and colleagues designed it so that statistical information about page rankings could be shared between the different data centers. This would allow each data center to run an algorithm that compares its results with those of others. If another data center gave a statistically better result, the query would be forwarded to it.

Google gave the first demonstration of its Chrome operating system today, at the same time opening the source code to the public. The company highlighted features that have grown out of what vice president of product management Sundar Pichai called "a fundamentally different model of computing." Unlike other operating systems, which merely incorporate the Internet, Chrome is completely focused on it.  


The Chrome OS is based so aggressively on the Internet that devices running it will not even have hard drives, Pichai said, emphasizing that "every app is a Web app." All data will be stored in the cloud, and every application will be accessed through the Chrome browser. Because of this, he added, users will never have to install software or manage updates on the device.

The user interface closely resembles the Chrome browser. When the user opens applications, they appear as tabbed windows across the top of the screen. Users can stick their favorite applications to the desktop with one click, creating permanent tabs for them.

Pichai coyly demonstrated the way the Chrome OS can deal with competitors' file formats. He inserted a USB drive into a laptop running Chrome OS, launching a window that showed that the device contained several Microsoft Excel files. When he clicked on one of the files, the system automatically pulled up the Windows Live Web-based version of Excel, opening the file inside.

"It turns out that Microsoft launched a killer app for Chrome OS," Pichai said, adding that anyone who writes a Web application is writing an application for Chrome by default.

The effect, Pichai hopes, is "speed, simplicity, and security." Today's version of the operating system can boot up in seven seconds and open a Web application in an additional three, he said. Google engineers are working to make those times shorter.

The implications of the Web-focused design were spelled out more fully by Matthew Papakipos, engineering director for Chrome OS. Part of the security scheme for Chrome is that it's hard to make any unauthorized changes to the system, he explained. The root filesystem, which stores the core files needed to make software run, is stored in a read-only format. On top of that, every time the user boots the machine, Chrome OS verifies cryptographic signatures that ensure that the operating system software is properly updated, and matches the build Google has approved.

Choosing a home page is still an important step for many Web users. Nowadays, many home pages are custom-built, featuring headlines syndicated from favorite blogs and news sites and widgets that display the latest weather and sports scores, social network updates, and more. 

Netvibes, a startup based Paris, France, that lets users build custom home pages, is testing a service that pulls together real-time data from Twitter and Facebook, as well as frequently updated blogs and news sites, on personalized home pages. Called Wasabi, the new service is built on technology that helps keep up with an avalanche of real-time information from across the Web, says Freddy Mini, the company's CEO.

Competing services, including iGoogle, Bloglines, and Pageflakes, take slightly different approaches to building personalized home pages, or "dashboards." Netvibes's decision to focus on real-time Web content reflects the growing importance of sites like Twitter and Facebook. Currently, Netvibes has 3.5 million active users. Wasabi is open to 20,000 beta users, according to Mini, and about the same number are on the waiting list.

Once you activate Wasabi, you can choose a "smart reader" view in the upper-right corner of the screen. This view consolidates previously separate RSS boxes into a stream of intermingled headlines. Twitter and Facebook updates and other information, such as the current weather and e-mails, are shown in the same feed. You can highlight particular feeds via a navigator on the left of the screen. And it's possible to view a "mosaic" of any images associated with the items in a feed.

A Canadian startup has developed a small prototype wind turbine that uses friction instead of a gearbox to convert wind energy into electricity. CWind, based in Owen Sound, Ontario, recently began work on a larger two-megawatt prototype. The company claims that its "friction drive" system is more efficient and reliable--and less costly to maintain--than conventional wind turbines, which are prone to expensive gearbox failures.

A desktop instrument recently approved by the U.S. Food and Drug Administration might finally bring pharmacogenomic testing--the use of a patient's genetic information for drug prescription decisions--to the mainstream. The device, made by Nanosphere, a startup based in Northbrook, IL, can, in a matter of hours, detect genetic variations in blood that modulate the effectiveness of some drugs. Dubbed Verigene, the technology employs a combination of microfluidics and nanotechnology, housed in a single plastic cartridge, to pull DNA from a blood sample and then screen it for the relevant sequences.

Local search is important and as the volume of information (web pages, businesses, products, etc) continues to be so overwhelming, more people will start to make their world a little bit smaller.. and search locally.

Google offers a service called the "Google Local Business Center". Although it is a separate service to its maps product, they are closely linked. Google maps gets its business information from a variety of sources – including its own database (aka Google Local Business Center). Although there are other sources, if you want to get listed in Google maps quickly – Google Local Business Center is the best place to start.

The great thing about it is that you can get listed in the Maps (find a business) section within 24-48 hours of verifying your listing. It then can take up to 10 days to appear in the local listings that show up in Google’s main results (aka the "LocalOneBox"). This is great news – where else can you get listed at the top of Google within a few days… and for free?
