Latest innovations on Codeforces [January 2021]

Hello everyone!

The Codeforces team is working hard every day to improve the platform. Here's a quick overview of the latest innovations.

Mashups deletion

Until recently, there was no way on Codeforces to completely remove mashups you created. They stayed "hanging" in the interface and could get in the way if there were a lot of them.

Now you can delete the mashups you created. To do this, go to the edit page:

Edit page

At the bottom of the page there will be a delete button:

Delete button

Deleting a mashup is reversible, meaning you can restore it if necessary. You can view deleted mashups by clicking on the link below the table with mashups.

Other innovations

  • Added filter by contest format (IOI or ICPC) in mashups and gyms.
  • Compiler versions updated: Python 2 up to 2.7.18, Python 3 up to 3.9.1, Ruby up to 3.0.0, Go up to 1.15.6, Rust up to 1.49.0.
  • Now you can hide streams from the calendar.
  • The page with the list of user's contests now shows when the contest started.
  • The group invites page now shows who invited you.
  • Now you can massively change problem indices in mashups. Previously, to renumber problems in the mashup, you had to edit each task separately.

Thank you for including the month/year in the title!

I've been thinking lately displaying the year or newness or something next to each entry in Recent Actions would be good, since frequently update or policy posts get bumped year after year.

    Adding to this, any plans to revamp the blog/forums system in general (having different sections, seeing more than just most recent posts, etc.)?

Is it possible to add unrated contests like Kotlin Heroes, Q#, etc. to the user's contests page?

In mobile version of codeforces, the top-bar (with hamburger button) only appears if screen width is <= 800 px. This results in no top-bar when my mobile is rotated horizontal. Please increase this limit.

It will be better if there is a check box option "hide participated contests" on the contest page like "hide solved problems" check box on the problemset page. Then we don't have to scroll a lot to find a contests for doing virtual contests.

Please add the feature to keep the rating and tags part of the problem in spoiler form rather than changing it from settings.

Problems tags

Just my thoughts:

  • Add checkbox "show unofficial" in mashup standings. It's very confusing that you don't see upsolved submits in mashup and to show it you have to go in any round and click "show unofficial" there.
  • OUT_OF_COMPETITION doesn't work for mashups.
  • Go to source of problem feature doesn't work for mashups within group.
  • It would be nice to have list feature in contest page with tasks (to see what task were solved by people from the list)
  • I would like to have ability to hide unsolved tasks in archive, to be able to compile mashup from tasks which I solved.

Also, is it possible to attach link to resource from polygon? I want to give link to visualizer but I have to upload it somewhere else because I have no idea how to get link to it inside polygon.

Hey geranazavr555, currently the API for requesting information about CF users states No more than 10000 handles is accepted, yet at the moment at most 300-500 users can be requested at a time. This is a bottleneck for developing discord bots and tools using the CF API and leads to a lot of API calls needing to be made to implement certain features. Could you look into this?
