While I have the RHCE, one of the more popular Linux certifications is the Linux Professional Institutes’s LPI. While not as “intense” as the RHCE, the LPI confers a core level of competency on Linux systems. A competency that is fairly distribution agnostic.
While in the process of looking up documentation models on the Internet; I ran into wikibooks.org. Wikibooks is an attempt to create an on line book repository the likes of wikipedia does for the encyclopedia. The array of books available for access it quite amazing, ranging from cookbooks to foreign language guides. Most of the books have a educational slant on them, but that is generally the kind of book I am looking for when searching for on line book content.
How does this tie into the LPI? Wikibooks has a complete (if unofficial) list of prep books for the LPI. Notice the LPI level 3 is still in preparation by the Linux Professional Institute.
In an semi related link, I have been reading up on Ade’s blog post proposing an on-line KDE course catalog of how to documents organized in a collegiate format. He calls his proposal UofKDE. Overall I think the idea is a great improvement over the current on line documentation organization (or lack of it.) Maybe this will start to put the design level of KDE’s documentation more on par with KDE development environment. I think its about time for a open source documentation revolution; particularly in the KDE world. And the innovations in that field will not be made with the same level of thinking got us to were we are now.
