Caffeine - Google New Search Engine

This week tech bite is Caffeine , new search engine from Google.

What it will do:

This is new version of Google search engine providing better search results faster. That means search results will be more accurate. Fake sites will be de-indexed by new version.

How it Works:

The new infrastructure sits "under the hood" of Google's search engine, which means that most users won't notice a difference in search results. But web developers and power searchers might notice a few differences in speed and accuracy. There are so many technical changes underlying this new version, results will be indexed in real-time as the search engines of Twitter and Face book.

When it is Coming: Developer’s preview available at http://www2.sandbox.google.com/ (When I tried it was unavailable). Full blown version will come soon.

Where is this useful: Envelope on size indexing speed, accuracy, comprehensiveness and other dimensions.

Hyper V

This week tech bite is Hyper V. Previously codenamed Viridian , is a Virtual machine technology for Windows Server 2008.

What it will do:

Several servers can run side by side on a single machine. Helps in server consolidation.
Development and testing environments can be consolidated to one.
Virtualization can be done from Desktop to Datacenter level.
Legacy application re-hosting. Legacy operating systems and applications can run on new hardware along with more recent operating systems and applications.
