Avoid package to be update on Gentoo

It's possible with Gentoo to keep a version of a package and mark it as no updatable.
To do that, you have to modify (or create if it doesn't exist) the file /etc/portage/package.mask.
Then add the package version in this file.

Example :

vi /etc/portage/package.mask

>x11-drivers/nvidia-drivers-180.60

So when you will make emerge -p world, you will see :
[ebuild R ] x11-drivers/nvidia-drivers-180.60

So the package can't be update.

Install locate command

To install locate on your gentoo : emerge sys-apps/mlocate
Then make updatedb

Dead key and compose key definition

Here is a good definition of what is dead key and compose key that i found on wiki.linuxquestions.org :

If you press a ` and an e, you get an è. In this case the key ` is called a dead key because it is at first stroke dead. A bit more tricky is the compose key. Press the compose key and then type two keys, and both keys will be combined. E.g. type the compose key, then the comma, then c and the outcome is ç.
