"Farm" slang terms

[Eric Christopherson]

Hi, all. I'm looking for information on slang terms with the word "farm"
in them, relating to computaters; especially the origins of such terms.
I've known "cube farm" (a bunch of cubicles where office workers work)
and "render farm" (a cluster of computers used for graphics rendering in
parallel) for a long time, but just recently I found a reference to
"link farm" as meaning "an incremental backup consisting mostly of links
(most likely hard links) to the relevant files in the preceding
iteration of the backup"; but this page
<http://onlineslangdictionary.com/meaning-definition-of/link-farm> says
"a website with little or no content, consisting of mostly (or entirely)
links to other websites."

So, does anyone know what the first such "farm" slang term was, and when
and where it originated? And how about other terms with "farm" in them?
(I came across a new one the other day, but of course I've forgotten it
now.)
