I recently discovered a set of mathematical programming challenges ranging from very simple to extremely complex. http://projecteuler.net/ I find that they are a great tool for studying Perl, because it gives me a concrete target to work on and apply better coding techniques.
Does anyone have suggestions (or a site) for similar challenges based in text parsing and management? MARC related would be best, of course, but anything leaning more toward text than math would be appreciated. Thanks, Mike Barrett
