I'm a huge fan of Douglas Comer's classic, "Internetworking with TCP/IP." I have the second edition from 1991. I remember that when this book came out, everyone was talking about at Reiter's Scientific Bookstore here in DC, a place where lots of geeks hung out. It really changed my outlook on networks -- no longer did I see them as a proprietary means of connecting one vendor's stuff. Comer showed how TCP/IP could seamlessly bring it all together.

Actually, I found this part of the article rather humorous. Imagine a fire department that has a policy to never talk about fires. Or a hardware store where the employees aren't allowed to talk about hardware. What do employees at MSD do all day? Hmmm.... "Todd Fogarty, a spokesman for MSD Capital, declined to discuss the Red Hat investment but pointed out that 70 employees work for the New York investment firm. 'It is our policy not to talk about investments,' Fogarty says."
