After a 20+ year recess from Linux, I'm going back and re-teaching myself. While looking for resources I came across a pre-owned copy of O'Reilly Press "Building Linux Clusters" written by David HM Spector. I was unaware when I ordered it that the CD which should have been included, wasn't in the book when it arrived. I'm still reading about and working with some basic Ubuntu free online classes, so I don't really need the information in the book immediately, but I would like to find a source where I can get a replacement for the CD. Even if it's dated material as the first addition to this book was written in July of 2000, it would be a starting point for some information.
