8/2 What does "x (mod y)" in mathematics mean?
\_ how are you a computer science undergraduate without knowing this?
it's the remainder of x divided by y.
\_ Use the distributive property:
x (mod y) = (x mod) (x y)
Makes sense now?
\_ I still don't get it. What does the latter mean?
\_ Man, I was kidding. Sorry about that. Seriously,
though, "mod" just means the remainder, like from
elementary school. So for example, 4 mod 3 is 1.
\_ You are missing the minor technical distinction between
"x mod y" and "... (mod y)", see below. -alexf
\_ Well there was no way for me to tell he was referring
to FLT until he brought it up. That would have changed
my explanation.
\_ But that's not the theorem. It shouldn't be
an = sign, but rather a "congruent" symbol,
which is 3 horizontal lines. It'd take a
little too much time to explain, so I'd
pick up a Math 55 text for more details.
\_ Well there was no way for me to tell he was
referring to FLT until he brought it up. That
would have changed my explanation.
\_ You're not being blamed; your explanation is
reasonable given that you weren't specifically
asked for distinction between mod and (mod).
-alexf
\_ I just read about the Fermat's Little Theorem, which
states "Let p be a prime which does not divide the
integer a, then a^(p-1) = 1 (mod p)". I don't understand
what the "1 (mod p)" part means. Isn't "1 (mod p)" always
1 for all p greater than 1?
\_ "(mod p)" after an _comparative statement_ means that
that statement is checked only after taking the
remainders of both sides when divided by p. So, the
following two lines, e.g., are equivalent:
a=b (mod p)
a mod p = b mod p
(Note that to make the different meaning of the "="
clear, the "proper" way to write the first line uses
a 3-line "=" sign instead of the usual =). -alexf |

8/2 Anyone knows how to make the auto-archive in ~mehlhaff/tmp/motd,v work
again?
\_ mehlhaff does.
\_ yeah make soda stop rebooting
\_ That's like selling your sister into prostitution and
you being the pimp. You can make a quick buck or two
now, but it's going to bite your ass eventually (or
perhaps your sister will bite your nuts off).
Basically, the US Defense is nothing more than a leaky
condom for Bush's presidency. Sure you didn't get a
VD this time, but how many ho's are you going to pass
through before you pick up AIDS?
The government needs to spend money, yes. Not ON THE
MILITARY though. Funding worthy projects like
environmental protection, cloning research,
nanotechnology, etc. are where the efforts should be
made. Instead all those situations are being
castrated. Darwinism in reverse.
\_ Linux. Linux is the STANDARD. Way to make soda stop
rebooting. |

8/1 On a four button suit, all 4 buttons are buttoned, right?
\_ four button suit is queer.
\_ man, i totally disagree with this slacking "button only
some buttons" bullshit. you got bottuons. you either leave them
open or close them. what's this "can't go either way" bullshit?
\_ No, you leave the bottom button undone. -ausman
\_ I thought this only applies to two-button suits.
\_ I think that this applies to all single breasted suits and
all vests. Its some english thing, some king did it that
way two hundred years ago so we have to honor tradition or
some garbage like that.
\_ you can go your own way. (go your own waaaay...)
unbutton the 2nd from the top.
\- 4 button suit was queer, then stright guys who were non-large
began wearing them. i believe you button all the buttons. on some
\- looks like a bunch of web sites say all
except bottom one as with other single-b
suits. --psb
[ reformatted - motd reformatting daemon ]
\_ Its that english king thing that I was
talking about. Its all very stupid anyway.
depending on the lapel cut it is probably ok to but up to the 3rd.
selecting the currect knot [half or full] probably matters more with
a 4b suit. i think the height of the 4b suit wave has passed but i
just got one. anyine have tv or web page evidence you do button
bottom button? tastefully, non-gay, --psb
\_ Related question, how many sodans actually wear suits for something
other than weddings? I've got a suit and a blue blazer and I rarely
use them. The last time I wore the blazer was on my trip to india.
(I needed a jacket with a lot of pockets that were hard to pick).
\_ I wear suits to interviews. |

8/2 I'm trying to do a crappy home movie for my brother as a gag gift
and I'm looking for some sort of long, burning, fuse wire. It needs to
burn hot enough to light a match at the end, but cool enough not
to singe carpet or cheap wooden furniture (excessively). motd points
to whoever can name this product, tell me where I can get it, and how
much it'll set me back. thanks.

8/2 Dell says no to Linux on the Desktop:
http://news.cnet.com/news/0-1003-200-6757216.html?tag=mn_hd
Looks like bill will lunch on Penguin instead of the other
way around...
\_ whatever...the only reason anyone orders linux desktops is so they
don't have to pay for windows (but will use existing copies). just
buy from a mom n' pop, better deal anyway. dell still doesn't offer
AMD. dell sux...except perhaps the laptops. furthermore, dell cites
slow demand as the reason, while I'll bet most consumers didn't even
know about the option because the marketing was nonexistent and it
was hard for me to find on the site even when I knew about it. plus,
the options list was limited compared to the win boxes.
\_ Actually Dell desktops are fine but I'd look for the laptops
elsewhere (e.g. IBM)
\_ IBM has been overpriced whenever I compared the two...and
didn't offer the latest stuff like GF2go graphics etc.
\_ dell laptops are pieces of shit
\_ well, okay. never had one.
\_ Dell laptops consistently win quality tests and are
well priced for the size and hardware they include.
What's your beef?
\_ they break constantly and they're not well-designed.
\_ I'd agree that they have failed to market the Linux desktops
properly. Most people were not even aware that they sell them.
And those who were aware often would be greeted with broken links
and such when they went to http://www.dell.com/linux and clicked
on Dimension or Optiplex.
\_ VA Linux, where are you?.. |

8/2 How do you get vi to autowrap lines at n characters per line? Let's
say 72 for example's sake.
\_ :set wrapmargin=n where n is some number.
\_ Thanks. Incidentally, on my vi it turned out to be
:set wrapmargin=(80 - n)
but your answer got me on the right path. |

8/2 Why install linux when the selection of out of the box software in
the stores is not that great? This is not a troll.
\_ Fewer crashes than NT, I guess.
\_ Most out-of-the-box software in the stores is shit. |
