WHAT IS WINDOWS VIENNA?

http://fc09.deviantart.com/fs27/f/2008/071/3/4/Windows_Vienna_Concept_by_Kroanor.jpg

Windows "Vienna" (formerly known as Blackcomb) is Microsoft's codename for a future version of Microsoft Windows, originally announced in February 2000, but has since been subject to major delays and rescheduling.

The code name "Blackcomb" was originally assigned to a version of Windows that was planned to follow Windows XP (codenamed "Whistler"; both named after the Whistler-Blackcomb resort) in both client and server versions. However, in August 2001, the release of Blackcomb was pushed back several years and Vista (originally codenamed "Longhorn" after a bar in the Whistler Blackcomb Resort) was announced as a release between XP and Blackcomb.
Since then, the status of Blackcomb has undergone many alterations and PR manipulations, ranging from Blackcomb being scrapped entirely, to becoming a server-only release. As of 2006, it is still planned as both a client and server release with a current release estimate of anytime between 2009 and 2012, although no firm release date or target has yet been publicized.

In January 2006, "Blackcomb" was renamed to "Vienna".
Originally, internal sources pitched Blackcomb as being not just a major revision of Windows, but a complete departure from the way users today typically think about interacting with a computer. While Windows Vista is intended to be a technologies-based release, with some added UI sparkle (in the form of the Windows Aero set of technologies and guidelines), Vienna is targeted directly at revolutionizing the way users of the product interact with their PCs.
For instance, the "Start" philosophy, introduced in Windows 95, may be completely replaced by the "new interface" which was said in 1999 to be scheduled for "Vienna"

(before being moved to Vista ("Longhorn") and then back again to "Vienna").

The Explorer shell will be replaced in its entirety, with features such as the taskbar being replaced by a new concept based on the last 10 years of R&D at the Microsoft "VIBE" research lab. Projects such as GroupBar and LayoutBar are expected to make an appearance, allowing users to more effectively manage and keep track of their applications and documents while in use, and a new way of launching applications is expected—among other ideas, Microsoft is investigating a pie menu-type circular interface, similar in function to the dock in Mac OS X.

Several other features originally planned for Windows Vista may be part of "Vienna", though they may be released independently when they are finished.
"Vienna" will also feature the "sandboxed" approach discussed during the Alpha/White Box development phase for Longhorn. All non-managed code will run in a sandboxed environment where access to the "outside world" is restricted by the operating system. Access to raw sockets will be disabled from within the sandbox, as will direct access to the file system, hardware abstraction layer (HAL), and complete memory addressing. All access to outside applications, files, and protocols will be regulated by the operating system, and any malicious activity will be halted immediately. If this approach is successful, it bodes very well for security and safety, as it is virtually impossible for a malicious application to cause any damage to the system if it is locked in what is effectively a glass box.

Another interesting feature mentioned by Bill Gates is "a pervasive typing line that will recognize the sentence that [the user is] typing in." The implications of this could be as simple as a "complete as you type" function as found in most modern search engines, (e.g. Google Suggest) or as complex as being able to give verbal commands to the PC without any concern for syntax. This former feature has been incorporated to an extent in Windows Vista.

Microsoft has stated that "Vienna" will be available in both 32-bit and 64-bit for the client version, in order to ease the industry's transition from 32-bit to 64-bit computing. Vienna Server is expected to support only 64-bit server systems. There will be continued backward compatibility with 32-bit applications, but 16-bit Windows and MS-DOS applications will not be supported as in Windows Vista 64-bit versions. They are already unsupported in 64-bit versions of XP and Server 2003...

Any doubts please post comments so that i can learn more..

I think by knowing this information you can surely know the difference between the other windows os's

What would happen if the Earth stops spinning?

Had you ever thought of it.If not then think now.Of course the likelihood for this actually happening in the next few hundred millions years is just about zero. But we can still speculate on what would happen anyway.
Earth is rotating at a speed of about 1100 miles per hour. If our planet suddenly stopped rotating, the atmosphere would still be in motion at that speed. The atmosphere would be moving so fast it would literally sweep the land masses clear of anything not anchored to bedrock, this would mean rocks, soil, trees, buildings, people and animals. All would be swept up into the atmosphere.
If the Earth's rotation slowed down gradually over millions of years, and this is the most likely scenario, it would be a very different story. If the Earth slowed down to one rotation every year, called synchronous rotation, every area on Earth would be in either sunlight or darkness for one year. This would be similar to what the Moon goes through where for two weeks the front side of the Moon is illuminated by the Sun followed by the front side being in darkness for two weeks.
But what if the Earth stopped rotating completely? In that case, one half the Earth would be in daylight for half the year while the other side would be in darkness. The second half of the year it would be reversed. Temperature variations would be far more extreme then they are now. The temperature gradient would affect the wind circulation also. Air would move from the equator to the poles rather then in wind systems parallel to the equator as they are now.
Even stranger would be the change in the Sun's position in the sky. In the above scenario, Sun would just have a seasonal motion up and down the sky towards the south due to the orbit of the Earth and its axial tilt. You would see the elevation of the Sun increase or decrease in the sky just as we now see the elevation of the Sun change from a single point on the Earth due to the Earth's daily rotation.
As an example, say we live at 30 degrees North latitude. In the Summer, at a longitude where the Sun was exactly overhead, it would slide gradually to the horizon as Fall approached, but since the Sun has moved 90 degrees in its orbit, it would now be due west. As Winter approached, you would now be located on the dark side of the Earth. You would have to move to a longitude 180 degrees around the Earth to see the Sun 1/2 way up the sky because in the Winter, the Sun is 50 degrees south of its summer location in the sky.
There would be other effects of the Earth's rotation slowing also. The magnetic field of the Earth is generated by a dynamo effect that involves its rotation. If the Earth stopped rotating, the magnetic field would no longer be regenerated and it would decay away to some low, residual value due to the very small component which is 'fossilized' in its iron-rich rocks. There would be no more 'northern lights' and the Van Allen radiation belts would probably vanish, as would our protection from cosmic rays and other high-energy particles. Losing this protection would cause serious health issues.
Be glad for our Earthly rotation, without it we would be much worse off!
