As this 3rd beta-year comes to an end, we would like to host an event: The Best of Code Review 2013. All Code Review users will be invited to nominate (link to) the best questions and answers from this year, and showcase them as examples of what great CR questions and answers should look like.
There's just one problem: we need to agree on categories! Please post your category ideas here, one idea per answer please. The most upvoted ones will be retained. (downvotes don't count!) We have six categories for best-of in 2013!
Conclusion
The winners of Best of Code Review 2013 are:
Night and Day (the most dramatic improvement): (with 4 meta votes)
I'm awarding 100 points to Gareth Rees for the answer and 50 points to Cris Stringfellow for posing the question.
Exterminator (answer that points out the most obscure bug): (with 7 meta votes)
I'm awarding 50 points to rolfl for the answer.
Diplomat (most tactful advice): (with 7 meta votes)
I'm awarding 50 points to rolfl for the answer.
Gordian Knot Untied (best justification for rewrite): (with 3 meta votes)
I'm awarding 50 points to Gareth Rees for the answer.
Not as easy as it looks: Tie with 3 meta votes each:
- Project Euler 407: Is there any more optimal way to solve this idempotent equation (modulo n ring)?, posed by ilia-sucholutsky
- Optimising Funny Marbles, posed by user2369284
As neither user has posted any answers on Code Review, no bounty can be awarded for their interesting questions. (In my opinion, Project Euler 407 never looked easy in the first place!)
Thousand words (best image): (with 5 meta votes)
- Parallel Universe Time generator, answered by 200_success
Although the nomination was for the answer posted by 200_success, the image in the question was pretty useful too.
As suggested by @retailcoder, I am awarding bounties to winners in the first four categories, as noted above.
I hope that Best of Code Review 2013 has helped to showcase contributions from our members — not just the winners, but the other nominees as well. Hopefully, we can make this event an annual tradition!
