the power method for calculating the first eigenvalue/vector of a (sparse) matrix. This is what Google Page Rank does.

there's a range of quality / popularity metrics we'd like to implement. Others include:

  • most dependend upon
  • most downloaded
  • code coverage above a cerain percent (e.g.. 75% minimum)

Additional ideas for metrics:

  • % of exported definitions with haddock comments (should be 100%)
  • Bonus points for being -Wall safe, unless specific warnings have been deliberately excluded (shows they care and think about warnings)

I would say haddockness is more important than coverage, and coverage is more important than -Wall.
