Learn Linux with IBM and these Linux Professional Institute tutorials
The Linux Professional Institute (LPI) certifies Linux System Administrators. Even if you’re not interested in the certification itself, you may still be interested in learning Linux in general and the following tutorials, from IBM’s DeveloperWorks, will help you.
These tutorials serve as a comprehensive self-study guide so you can take the exams with confidence.
IBM DeveloperWorks – Linux LPI Tutorials. Here’s an example of what you may find.

Configure XDebug with Bitnami PHP Stacks on Linux Ubuntu
Fact is that if you want to develop something more than a dynamic menu in php, you’re going to need a debugger. You’re going to need it badly and you don’t even know it (shame on you!).
So let’s start from the beginning. You got bitnami lapp (or lamp) stack because it’s cool and doesn’t need so much configuration (if any at all). So you’re basically ready to start coding.
You realize you need a debugger. You search for it and you find out about xdebug. Cool. Then you approach the Xdebug download page and you see only sources and many windows binaries. Not cool.
Reset aspetto di Gnome senza reinstallare Linux
Dopo aver smanettato per giorni con temi e aspetto di Ubuntu Linux, mi sono ritrovato con un obbrobrio di interfaccia utente. L’unica cosa che volevo fare era reinstallare Ubuntu da zero e ricominciare.
Il problema
Mi mancava l’interfaccia pulita, la leggerezza di un sistema appena installato. I puntatori del mouse erano inconsistenti, così come i bordi delle finestre. Persino i menu. Avevo personalizzato (e devastato) così tanto l’interfaccia utente che sembrava di usare un Mac OS versione Chernobyl.
La prima, ovvia, soluzione era quella di reinstallare il sistema. Il fatto è che avendo una partizione dedicata per /home, tutti i miei settaggi, compreso l’aspetto di gnome, sarebbero riapparsi come per magia sul nuovo sistema operativo.
