I'm trying to help a nice young person in her quest to find a career other than "loading gock security guard" and she has a H-u-g-e and very dry textbook which she says isn't too easy to read; I told her I'd see if there might be a supplemental beginner's guide to support her in reading this other book and she brightened up. Any suggestions for me to look into? By the way, is Citrix a form of virtualisation? Would "Virtualization For Dummies" be a good book to try? Hope someone can offer a suggestion! Thanks in advance and by the way, Happy Holidays to anyone who would like to enjoy holiday wishes!
