LibreOffice - Setting UI Language

http://help.libreoffice.org/Common/Selecting_the_Document_Language

Setting UI Language A standard installation of LibreOffice software will give you a user interface (UI) of your chosen language.

Most users download the American English version, which gives you English menu commands and English application help. If you want another language for the menus (and for the application help, if available in that language), change the UI language as follows.

• Choose LibreOffice - PreferencesTools - Options - Language Settings - Languages.
• Select another UI language in the "User interface" listbox.
• Click OK and restart the LibreOffice software.
• If the listbox doesn't list the language that you want, see "Adding More UI Languages".

CentOS x86_64 - remove i386/i686 packages

CentOS FAQ
http://wiki.centos.org/FAQ/General#head-357346ff0bf7c14b0849c3bcce39677aaca528e922.

I installed the x86_64 version, so why do I have i386 packages, and can I get rid of them?
CentOS follows the upstream source in this respect, as it does in general, and the x86_64 installation by default will install iX86 32-bit packages on a 64-bit installation for compatibility purposes.

Many server system administrators (and some desktop users) want a pure 64-bit system and so remove all 32-bit packages. This can be accomplished as follows:

yum remove \*.i\?86

To keep any 32-bit packages from being installed in future updates, edit your /etc/yum.conf and add the line:

exclude = *.i?86

Be aware that 32-bit applications, including some browser plugins that may only be available in 32-bit versions, will no longer work after this procedure.
You may also want to do this:

yum reinstall \* 

The reason is that sometimes the /usr/share/ items (shared between BOTH packages) get removed when removing the 32-bit RPM packages.

Git - local and remote branches

Some notes on handling git local and remote branches:

After creating a new local branch, push it to the remote server using:

git push origin newbranch

To delete the remote branch if no longer needed use:

git push origin :branchtodelete


However, in other copies of the repository, the deleted branch will still show, in order to update the local list of remote branches in other repositories use:

git remote prune origin
