# This is a method I use when working with slow ruby scripts that
# operate on huge datasets.
#
# It caches the return value of a block of extremely slow code
# in a file so that subsequent runs are fast.
#
# It's indispensable to me when doing edit-debug-edit-debug-edit
# cycles on giant datasets.

# loads ruby object from a cache file or (if cache file doesn't exist) runs

loaded 71 hackers
testing: s.matches_are_sane? = true
getting new hackers
 hacker1 will probably defeat hacker2
picking hacker1
@sequence = "L" (1)
i know about 1412 hacker matches
guessing accuracy ==   0.00%
checking on last guess and getting new hackers
last guess was good
