Eclipse Install new software fails

If you try to add new features from an update site and you get the following strange error:

Cannot complete the install because one or more required items could not be found.
  Software currently installed: Shared profile 1.0.0.1385682248052 (SharedProfile_SDKProfile 1.0.0.1385682248052)
  Missing requirement: Shared profile 1.0.0.1385682248052 (SharedProfile_SDKProfile 1.0.0.1385682248052) requires 'toolingwin32.win32.x86org.eclipse.equinox.p2.reconciler.dropins [3.6.2.M20110210-1200]' but it could not be found

Restart you eclipse as administrator and you problem will be solved.
It fails since you don't have write access to the folder where your eclipse is installed.

Git: creating and importing patches

A useful command when you need to contribute to open source projects:
1. Create a patch from your last commit (-n for the n latest commits). The following command will create a <myKillerPatch>.patch file in the current directory

   git format-patch -1

2.  Test the patch

   git apply --check <myKillerPatch>.patch

3. Finalyy import it

   git am <myKillerPatch>.patch
