Before i left the states last December, i set up an old box of mine with Fedora 12, and set it up for my family to use when the inevitable happens, the Windows machine breaks and no one can fix it anymore. Today my little brother asked me how he could get a java game going on the machine. Since the only way i know how to do it is via the command line, i started walking him through it, almost by default. Then it hit me. This is his first time using the command line. He's 10 years old. I'm sitting 6000 km away, and i'm walking him through the process. Over XMPP. This is Linux potty training, he's learning it the same way i learnt it.
In retrospect, i probably shouldn't have told him about sudo on day one.
