2008 Contest
The 2008 contest required entries to redact a rectangular portion of a PPM image in a way that the portion may be reconstructed. Any method of "blocking out" the rectangle was allowed, as long as the original pixels were removed, and the pixel reconstruction didn't have to be perfect (although the reconstruction's fidelity to the original file would be a factor in judging). The contest began on June 12, and ended on September 30. Entries tended to either xor the region with a retrievable pseudo-random mask or append the masked data to the end of the file format. The two placing programs both used improperly defined macros while the winner, choosing to work with an uncommon text based format, zeroed out pixel values while keeping the number of digits intact.

Famous quotes containing the word contest:
“Theologians should not be ashamed to admit that they cannot enter a contest with such antagonists [the sceptics], and that they do not want to expose the Gospel truths to such an attack. The ship of Jesus Christ is not made for sailing on this stormy sea, but for taking shelter from this tempest in the haven of faith.”
—Pierre Bayle (1647–1706)
