[humorix] Re: Advanced OS Questions only you can answer... (fwd)

[Rik van Riel <riel@conectiva.com.br>]

Hi,

I found this on one of the more technical FreeBSD user lists,
where some student tried to be smart enough to fool the FreeBSD
hackers into doing his homework.

(OTOH, if he could outsmart them, why couldn't he do his own
homework?)

Look, I don't think we want to confuse the kid.  It's bad enough that the
crossways "8 inches" just refers to a standard octet, but the vertical 11
inches is a 2^N thing.  It's worse still that, on most platforms, the page
is really 12 or 13 inches.

I wanted to start him with the easy case.
