in thread [OT] The statistics of hashing.

What I have a problem with -- as evidently you do too -- is deriving those formula.

Well, I'm sorry you didn't understand because I wasn't trying to help you convert between programs and formulae (hence why I left that step to you). I was explaining how to derive the most interesting part of the formula at hand (well, verify the derivation in order to understand it, since the formula was already provided).

I was not trying to teach you how to do integration nor how integration correlates to this sampling problem. I have no interest in trying to teach beginning calculus via a web forum.

But it seems your expressed desire "to understand" does not extend to trying to understand 1-exp(1-$inserts/$slots). Perhaps my explanation will assist others on that point.

But my explanation also serves as response to more than one private request you made to me, despite your apparent lack of interest now.

I seriously hope this will not offend you, but suspect it will.

I'm not sure why.

    You really are a supercilious sod aren't you.

    Why would I need help with that bit? It is already code.

    How about this. When I respond to someone asking for their help with materials they posted, you keep your often supercilious, rarely helpful, always patronising nose out of it. Is that a plan?

    With the rise and rise of 'Social' network sites: 'Computers are making people easier to use everyday'
    Examine what is said, not who speaks -- Silence betokens consent -- Love the truth but pardon error.
    "Science is about questioning the status quo. Questioning authority".
    In the absence of evidence, opinion is indistinguishable from prejudice.

    The start of some sanity?
