lion os application problem

After I installed Lion, I had duplicate applications in Launchpad.  I tried reinstalling Lion and they remained.  Another troubleshooting techniques was depressing control + option+ command and that yielded no results.  




How do I get rid of the duplicate applications?


Well this what I did.



This is a known bug in Lion. The Launchpad database does not update properly. More info can be had athttp://haiteq.com/2011/07/07/quick-tip-force-os-x-lion-to-reload-the-launchpads- contents/

To force the LaunchPad to refresh its database, run the following command in Terminal:
sudo rm ~/Library/Application\ Support/Dock/*.db
You'll be prompted not to mess with sudo commands, and then asked for your admin password. This will delete the database that is used to populate the LaunchPad.

To apply the change and make the LaunchPad create a new database, run this command:
sudo killall Dock
The Dock will restart, along with Mission Control and the LaunchPad. The grid of icons should be refreshed, and the changes you have made to the applications should be visible.

This worked for me, and only took a few seconds.

THIS IS ADVICE, WE CANNOT GUARANTEE IT WILL WORK FOR YOU, SO PLEASE NOTE ANY LOSS OF SOFTWARE AND APPLICATIONS IS YOUR OWN RESPONSIBILITY , 

LET ME KNOW IF IT WORKED

The city of Cupertino, Calif., has released new images of what the complex will look like. The 2.8 million-square-foot four-story circular structure will resemble a spaceship more than a building with huge walls of glass that let workers look out from both sides of the ring onto park-like landscaping. Dubbed  Apple Campus 2 , the headquarters will accommodate up to 13,000 employees and contain a 1,000-seat auditorium, 300,000 square feet of research facilities and underground parking. By moving vehicles underground, 80 percent of the 150-acre property will be landscaped with 6,000 trees under the direction of a Stanford arborist who will help restore some of the indigenous plant life to the property, including  apricot orchards .
