Eric, the author, says he won't accept any puzzle submissions because of attribution and legal issues. This seems like the wrong outcome for people who want to make the site better but don't want credit, compensation, or attribution.

Has anyone seen a site using an IP assignment agreement which is the equivalent of "take my work, I don't want credit, and it's just for your site"?

The Creative Commons CC0 license comes closest, but one could scrape those puzzles and create a competing site, which I'd guess Eric wants to avoid.

Many of the comments are about the event as a whole, but I'd like to commend the author for the day 1 puzzle, which I think is very cleverly written. Many people (including myself) use these as an opportunity to try out learning a new language, and the first puzzle does a good job of making sure you know enough basic operations for some of the puzzles coming up. The puzzle itself wasn't very difficult, you could do it by hand if you really wanted to, but it required you to know how to read and parse lines in a file, handle compound data structures, iterate through, and perform basic operations (floor, casting strings to ints, etc). I thought it was really well done, and creates the basic knowledge for the puzzles ahead.

Always enjoy doing these but there was one last year that nearly broke me. I think it was day15. It was the worst combination of mind-numbing coding and horribly hard to debug special cases. It was purely convoluted with very little to think about which makes for the worst kind of puzzles

That one wiped me out for a week too, and caused borderline psychological problems.

Ultimately though I realised that if I followed the description word by word, and made no assumptions, then I got the right solution. Still, a nightmare: you could pass all the examples, or even some alternate real sample data, and still get it wrong if you got the ordering slightly incorrect.

The problem is trusting the submitter. How do you make sure derivate work is not submitted?
