11/10   Here is a problem for you google employees to solve:  Yahoo Finance
        is a big big part of yahoo's revenues.  It's missing something that
        so far nobody has found a way to solve.  Keeping track of options
        pricing and displaying historical charts on options pricing.  The
        reason is that each stock has hundreds of calls/puts.  Nobody has
        yet figure out a way to store all that data and display it even
        after expiration.   I'd like to see such a feature on google
        finance.  It's a complex data archiving problem.  Anybody want to
        guess the storage required to store the daily option prices for all
        stocks for the latest 10 years?  And have it available for quick
        retrieval?
        \_ do your own job
        \_ I'll guess: a few dozen gigs at most.  Make dupes across a bunch
           of different systems for fast retrieval.  And: YOU'RE FIRED!
           \_ I could see it coming to several hundred megs a day, which would
              be maybe 100GB/year, but that's still chump change.
              \_ several hundred megs a day?  to store a bunch of easily
                 compressed numbers?  c'mon....  I felt I was being rather
                 conservative saying the whole thing would take ~40 gigs.
                 but yes whatever the real total would be in disk space, the
                 total cost is effectively zero for anyone with a real use
                 for the data.
 \_ not only has this problem been solved, it has been solved by just about
    every large financial house. maybe you should come up with another
    theory to explain why it's not on your favorite free consumer portal.
    have you thought about the relative population sizes of option-savvy
    traders vs the population of equity traders? --aaron

        \_ For next question, we'll ask why GOOG doesn't have a free level 2
           NASDAQ feed...
           \_ they haven't gotten past the level 1 boss yet.
