Adding 2 Factor Authentication to a Linux Laptop With Google Authenticator

Have you ever wondered how to provide additional security to your Linux desktop? Google Authenticator can help provide a two-step authentication process that requires both an authentication token and your password to log into your Linux desktop. This would require that an attacker know both your password and have your authentication device to successfully log in to your system.
A pluggable authentication module (PAM) is a way to integrate authentication methods into an API that enables different programs to be developed independent of the underlying OS authentication scheme. Linux provides a PAM system which we would take advantage of in this tutorial to integrate an additional check, along with user password, to grant access to the system.

Using DejaDup To Back Up Your Ubuntu Desktop

Déjà Dup is a nice graphical wrapper around the command line backup tool duplicity. It hides the complexity of backing up the Right Way (encrypted, off-site, and regular) and uses duplicity as the back end. Déjà Dup does not use cron or similar schedulers. Rather, it starts a program deja-dup-monitor when you log into your session. This keeps track of when you last successfully backed up and will wait until the next scheduled backup.

Back ups are very important. Probably something I should do with my desktops more often.
