Hello everyone,
Thanks to the new Codeforces API, I'm working on some new Codeforces tools in my website.
If you have any suggestions or you need any tool/feature to exist, please post it here and I'll be happy to implement it if it's possible.
Thanks, Ahmed Aly

List of users sorted by max rating. (For View all, Countries, Cities and Organizations).
Actually this may be also a great feature for your TopCoder Tools!
If it's possible to draw a histogram for number of problem you solved for each problem level (500,1000,1500,2000,2500)
so you don't ask yourself to solve D or E during contest and actually you never solve any problem as hard as D or E before so histogram will easily show you your current level.
Bear in mind that D or E ends up the 3rd easiest problem surprisingly often (at least in div1, where the problems aren't categorized as "totally easy" and "needs some actual thinking"), so it's not a good idea to base a strategy on that :D
But for Div2 is nice. :)
Group categorization for problems type
for example user choose certain topics to practice ( bitmask , MST , Greedy .. )
and the tool provide him with problems guaranteed to belong to this set of topics without knowing the specific topic of each problem in order to give him the chance to define the problem by himself.
Compare rating graphs :)
like this on TopCoder
put any number of handles and compare them!
You can install user script described here.
Rating tables featuring only active users (Those who participated in a contest within last 4 or 5 contests) ... Also filtering a contest standings by country would be a great thing.
I have made the 2nd feature(almost). I actually I had made it before the release of API's through web scraping. But I was not getting much time to test and release it publically. Link. Currently I have'nt put all the data. Just for contest with Id 26-35. I will add the rest soon. I have already written the script. Just a matter of minutes. Please tell if the interface is good.
PS — Those who do not belong to any country come under the category — 'Alien'
I think someone has deleted all of your sites tables with sql injection.
I can still access it. As I mentioned, currently I have put only Id's 26-35 in the table. The rest are being scraped in my local db.
I searched for other contests. :D
would love to see cf blog organised. if blog you are looking for disappear from recent actions section, then you google it, and you come up with weird buggy blog that makes you leave the page asap. i would appreciate to see cf blog look like so(stackoverflow) or some other cool forumlike view
can you do this? virtual rating — draw rating of virtual contests
Everyone will first copy the solutions and then send the solutions in virtual contest , so everyone can be International Grandmaster in rating of virtual contests.In won't be interesting.
no! clever person don't do like that.it will be useful for who can't participate in official contests.
Clever persons understand that virtual rating is useless.
sorry for being a bit off-topic, but
yay! :)
View contest scoreboard only for a given country(I am tired of iterating over all Bulgarians to make them my friends).
Country rating graph!
A tool like the one __MB used to have for top coder- what would my rating change be if I had been x-th. This way I can regret even more that I did not add these two symbols ;) I am not sure the rating system here will allow for that, tough.
For #1:See my comment.
Rating prediction
if its possible to add comment box in problems. So that users can ask to admin query regarding facing solving problems during running contest.
Already exist at codeforces
List of all solutions for a certain problem, like the topCoder summary.
Already exists. Go to the Status tab and select only displaying the solutions for a particular problem.
Registrants write blog posts for editorials, algorithm tutorials, algorithm questions.. It would be nice to filter these and have access to algorithm tutorials with less effort.
To make an archive of tutorial blogs.
Rating distribution and percentile. (like on topcoder)
Some years ago I saw PvP = Performance vs Petr for topcoder where you were able to saw how you did against Petr when both of you competed in the same contest, thus knowing in how many contests you won him (probably 0...) and in how many problems you got a better score (hopefully 1!).
Of course this could be generalitzed to PvT (Performance vs tourist) or performance against any other user.
It would be very nice to have this!
Any stats from list in TC record book will be interesting)
It takes too much time to add the new problems of codeforces to A2 online judge. For example, if I want to create a contest, I can add only problems their ID's 397 or less although we reach (till now) to 441.
Could you, please, fasten this process? Thanks in advance.
