Klaus Knopper, Creator of Knoppix Talks to DistroWatch 201
An anonymous reader wrote to us about an interview with Klaus Knopper the author/creator of Knoppix. Knoppix is "a bootable CD with a collection of GNU/Linux software, automatic hardware detection, and support for many graphics cards, sound cards, SCSI and USB devices and other peripherals. KNOPPIX can be used as a Linux demo, educational CD, rescue system, or adapted and used as a platform for commercial software product demos. It is not necessary to install anything on a hard disk. "

I bought a CD burner on sale from Target (for those outside the Target area, har har, see www.target.com -- large American retail chain, for the last few years has been working on its image as a modern general store up the totem pole from Wal-Mart). Then, burner unopened, I decided to trade it in when I saw they had a *duplicator* for $250. It's only one-source-to-one-target (not a fancy thing with internal drive or 16 target trays), but can copy a full CD in about 5 minutes. (Perhaps they do in some areas, but I've never seen CompUSA or such stores to carry duplicators -- I find it a strange but nice decision on target's part to stock them.)
The drive is the 2nd generation (they were clearing out the 1st gen recently, I wish I had bought one of those instead), and though it has the currently popular "crystal black" look, I wish the top were not swoopy, so I could rest other things on it, which is perhaps the designers' point, but hey.
