All of CCO 2014 problems have been added. Thanks to JeffreyZ for typing up all the statements!
You are just an ordinary programmer having a decent day while enjoying your early morning cup of tea. Suddenly, you notice two strange guys running around on the street in panic. You decide to go over to them and ask what’s up. Congratulations, you are now a part of their squad. After a lot of discussion, you find out that these guys are going after the one and only cheesecake recipe, and since you love cheesecake, you agree to help them out!
The contest will run from February 23th, 2015 at 3:00PM EST to February 24th, 11:59PM EST, within which you will have 3 hours to complete the contest.
The Old New Thing contest has started! You have 7 days to enjoy this implementation-only contest which gives an insight into the programming world of 1992. In this contest, you will learn a lot about the history of computer programming.
We have added all CCC 2015 problems to the Don Mills Online Judge.
You may find them here: http://www.dmoj.ca/problems/?search=%22ccc+%2715%22.
The JOI (Japanese Olympiad of Informatics) Open Contest 2014 problems have been added to the DMOJ.
Many of them use signature grading, unlike most of the DMOJ problemset.
JOI '14 problem 4, Migration, was an output-only task that was judged against other contestant submissions. Since the DMOJ doesn't have the required infrastructure (and it's not worth adding it for one problem), Migration has not been added.
Like charts? Statistics? Charts _and_ statistics? We do too. That's why we've compiled relative statistics regarding submissions in actually used languages on the DMOJ.
Are you interested in how other people did on the CCC, and are curious about your chances of making it into the CCO? Here's an unofficial poll where you can enter your score and check out others' scores. There's no penalty or anything if you lie, but there's really no point in doing so either, as the poll is anonymous.
"It would be really easy to put fake votes and make everyone panic but we're trusting people not to do that. Only vote if you wrote the Senior!"

Here is the editorial (with solutions) for problems 1-4 and problem 6 of UTS Open '15 (final rankings here). Jeffrey Xiao is bogged down with Spanish at the moment and will supply the editorial and solution for problem 5 as soon as he is able.
You can view the editorial here. Thank you for participating in the UTS Open - we hope to see you again next year!
