Feliz Navidad, Codeforces!

I'm a huge data nerd and an avid Codeforces user. I decided to combine these traits and make a service to provide everyone with some sort of their yearly statistics on this wonderful site in a neat form.

My main goals were to make a report card that:

  • contains insighful statistics;
  • is not overloaded with information;
  • is easy to share.

In persuit of that, I discarded multiple stats which were too boring, took too much space or were hard to implement within the limitations of CF API. I find the final choice of data really fun. I hope you like the result too!

The service is pretty intuitive to use. Enter your handle (in case you changed it, enter the one you had throughout the year), get the report card and share it with the world by clicking "open as image".

Disclaimer
Get Wrapped!→
Some examples
Some clarifications

Please, share your cards in the comments! (just use a spoiler as the image is pretty large).

Привет, Codeforces!

On Dec/18/2022 17:35 (Moscow time), Codeforces Round #839 (Div. 3) will start. This is a usual round for the participants from the third division. The round will contain 7 problems, which are mostly suited for participants with rating below 1600 (or we hope so). Although, as usual, participants with rating of 1600 and greater can register for the round unofficially.

The round will be hosted by rules of educational rounds (extended ICPC). Thus, during the round, solutions will be judged on preliminary tests, and after the round it will be a 12-hour phase of open hacks.

You will be given 7 problems and 2 hours and 15 minutes to solve them. The penalty for a wrong submission is equal to 10 minutes.

We remind you that only the trusted participants of the third division will be included in the official standings table. As it is written on the blog which you can access by this link, this is a compulsory measure for combating unsporting behavior. To qualify as a trusted participant of the third division, you must:

  • take part in at least two rated rounds (and solve at least one problem in each of them),
  • not have a point of 1900 or higher in the rating.

Regardless of whether you are a trusted participant of the third division or not, if your rating is less than 1600, then the round will be rated for you.

The problems were invented and prepared by Adilbek adedalic Dalabaev, Ivan BledDest Androsov, Maksim Neon Mescheryakov and me. We would like to thank the testers of the round: ermukanoff, Klyaksa, lankin.i, Fanarill, stAngel and DmitriyOwlet. Also huge thanks to Mike MikeMirzayanov Mirzayanov for great systems Polygon and Codeforces.

Good luck to all the participants!
