I have translated to Spanish the home page of The Perl Quiz of the Week.
The Perl Quiz of the Week is a wonderful project launched by Mark Jason Dominus: every Wednesday he proposes two Perl programming puzzles via a mailing list, and you try to solve them on your own. There is no winner, no competition whatsoever, it is problem solving for the fun of problem solving. After a mandatory initial silence of 60 hours people is allowed to share hints, solutions, compare approaches, etc., via a mailing list. A commented summary with some sample solutions is written by Mark himself and sent on Monday.
