How this certification program compares to CompTIA A+ ?
Disclosure: I worked on this program.
I rip on google a lot, but I can appreciate good work when I see it.
This course seems to be pretty comparable, but it also covers writing Ruby code, managing Chef, and using Git.
Of course another big difference is this course teaches you exactly what you need to know, while CompTIA leaves it to third-parties to write the training materials independently from the courses, so you're reading a 500 page book for a 100 question exam.
