Hacker Jargon

I really enjoy reading Phil Ringnalda's blog, and also his readers' comments. Every now and again, however, I encounter an interesting acronym or term and I don't understand what it means exactly (actually, this is more of a problem I encounter on Slashdot, but I digress). For instance, I suspect that it's not a compliment to be called a "troll", but exactly *is* a troll (and I'm not talking about the ones JRR Tolkien writes about)? And what does "RTFM" stand for (most recently encountered in the comments section on one of Phil's posts on a CSS slam?

Well, if you too would like the answer to these (and other) questions, look no further than The Jargon Dictionary! Please visit this fine reference for details, but here are the abbreviated definitions of "troll" and "RTFM" I found there:

• troll v., n.: 1. [From the Usenet group alt.folklore.urban] To utter a posting on Usenet designed to attract predictable responses or flames; or, the post itself.
• RTFM /R-T-F-M/ imp.: [Unix] Abbreviation for 'Read The [Fine] Manual'... . Note: I put square brackets around "Fine" because they used a different word but I'm trying to keep my blog PG-13.
