Let's assume that 10/11/2009 means October 11, as in the U.S.
Then you can use:
import System.Locale (defaultTimeLocale)
import Data.Time
thatMoment :: Maybe UT
I don't know about the other Linux distros, but Fedora seems to have excellent
support for Haskell.

Hello Dmitri,
It seems that your format pattern does not match exactly the format of
the input, thus the parser returns Nothing.
Try the following format string which seems to work with your date:
parseTime defaultTimeLocale "%m/%d/%Y %l:%M:%S %p" ds :: Maybe
UTCTime returns : Just 2009-10-11 19

If that's what Nikita has meant, then that's all fine. Hope there's no

Correction: the version in monte-carlo takes time O(n), but it only consumes k

There are time/space tradeoffs in sampling without replacement. The version in
monte-carlo takes space O(n) and time O(k), for all k. I chose this algorithm
instead of a streaming algorithm, with takes space O(k) and time O(n).
If k is much less than n, you can improve a bit. Here is a versio

When I review the original post I see only a question:
Does passwords

rather than a request.
So I'm not sure that was the intent.
I'm amazed that anyone (Sony!!!?) would store unencrypted passwords of

Thanks for the analysis.
So is this a problem that should be fixed in GHC?
And what can I do to circumvent the problem?
(Perhaps write some RULES magic?)

Dear all,
I am very puzzled by a program that contains
an "else" branch that is never executed,
but still seems to slow down the program.
(When I replace it by "undefined", the resulting program runs much faster.)
http://hackage.haskell.org/trac/ghc/ticket/5256
I thought it may be a type issue
Could you look at

Is it enough?

It looks like GHC, 7.0.3 "Haskell Hierarchical Libraries" documentation
generated for Win32, that goes with Haskell Platform installation package,
does not have a section on Data.Time module.
How can that be?

That works well for small numbers, but I'm guessing it will evaluate the
