Hello! It all begun in High School, when I saw my Physics teacher using a Brazilian distribution, Kurumin, about 6-7 years ago. He got me a CD, and from there I started downloading some distribuitions until I settled with Ubuntu 7.10 and now I'm with Ubuntu 9.04!

It was about 3-4 years ago, at take your kid to work day, one of the demos that I saw was running on a Knoppix dirsto. I was about 14-15 years old, thought it would be cool to try to use the Live CD of Knoppix. Wasn't. :( But, about a four months ago, I was looking at lifehacker.com's main page and saw an article about how to dual-boot with Ubuntu. Started with dualing booting between Windows 7 and Ubuntu 9.10 without internet (had a Netgear abpter that didn't work with Linux, I have brought a PCI one for Linux). After a half a month using Ubuntu, I ditched Windows 7 because Ubuntu is WAY better than Windows 7.
Just curious
