Central log server using rsyslog is an asset of your sysadmin life! It may get you on the surface on really critical failures when you manage xyz number of servers and some of them go down. In my case raspberry pi 2 with rasbian (debian wheezy for arm processors) does the job very well, without […]

Encrypting the $HOME directory under ubuntu/debian and other dists. In my case my $USER is “ubuntu” so be careful to replace that with your own user.

One of the more controversial changes in the Ubuntu 10.04 beta is the Mac OS-inspired change to have window buttons on the left side. We’ll show you how to move the buttons back to the right.
