A bit of background

First, some definitions (these are mine, based on my experience and what I have learned in classes)

n00b- a slang term used by many avid computer users for newbie. It is spelled that way because it is in "elite speak" or "1337". Elite speak is characterized by the substitutions in it, like 3 for e (E) or 5 for S, etc. etc. etc. If there is even a passing resemblance to a letter, it will likely be used. Extreme abbreviations are common as well. Hence leet for elite.

Open source- this one is a little more complex. Open source is the general name for any project that is worked on by a community of users volunteering their time and skills. Open source projects typically are not charged for, though many companies do charge for technical support, add-ons or a physical version of something. (i.e. charging for CD-ROMs to install Ubuntu). Donations are also very welcome by any open source organization. Wikipedia and the Wikimedia foundation are particularly well known for soliciting donations. Codes of conduct state that anything may be modified as long as it is publicly available for others to use or change as they will. One of the most widely know is Linux, which was started by Linus Torvalds in the early 1990s.
