04/730  I forgot my calculus, please help me out. does the line integral of
        a function f(x,y) compute the length of the function on top of that
        line, or the area of the function above that line? (e.g. does the
        line integral of a hemisphere calculate the length of the arc above
        the line, or the area of the half-circle above the line?)
        \_ i predict that you will be much more satisfied with the responses
           to your question of you tell us *exactly* what the problem is.
                \_ I did already, look in the parens.
                   \_ the "line integral of a hemisphere" makes no sense.
                      one takes the line integral of a *function* along a
                      *path*.
                        \_ a hemisphere is a function.
                           \_ a hemisphere is not a path. a half-circle
                              is perhaps what you're thinking of?
                   \_ You want a surface integral if you're integrating over a
                      surface.
        \_ asking these type of questions on a sysadm infested forum will
           get you nowhere
           \_ i am not a sysadmin, and i have a math degree. it's justa
              badly phrased question.
              \_ ditto.

3/7     My sister is graduating soon with a decree in information management.
        She was orignally CS, but couldn't cut the math, so her GPA sucks.
        However, she has had a couple of internships and did fine.  She did
        desktop support at RockYou and is currently doing web programming
        at UC Santa Cruz, but they can't keep her on after graduation.
        Anyone got any jobs?  She wanted to be a network admin, but right now

9/18    I forgot my math.  Say the probability of a bug happening is the
        unknown fixed value p in [0,1].  I attempt to reproduce the
        bug until it happens once.  Then it happens at my n-th trial, so I
        stop.  Now, what is the expected value of p?  Is it E(p) = 1/n?  Thx.
        \_ Did a quick program to test.  Looks like E(p) = 1/n
           (given assumption n(p) = sum x = 1 to inf of x*(1-p)^(x-1)*p

8/1     Yahoo to get 88% of the ad revenue in team up with m$.  Y!m$,
        discuss?
        \_ I thought Jerry Yang would never sell!
           \_ He's gone, replaced by some broad.
        \_ 88% of pittance is still pittance, I don't know how people
          think there is money in click through ads.  Who clicks on them?

        To those in academia, how do you organize the journal articles
        you keep (hard copies, that is)? By date? Author? Subject?
        Something else? Thanks.
        \_ I am not in academia, but author makes most sense. If you want, you
           can group by subject (Sun Spots, Solar Wind, Solar Flares) and then
