Hi everyone,

I've just finished the first Codeforces tools website, currently it contains only one feature called all users table.
This table is similar to Codeforces rating table, but with this additional columns:
- Number of Tried Problems
- Number of Solved Problems
- Solved Problems Percentage
- Number of Successful Hacks
- Number of Unsuccessful Hacks
- Contribution Rank
- Contribution

Also you can sort the table according to any column by clicking on the column header, it may take couple of seconds to sort the table as it's very big, also it may take few seconds to load the table.
There are some important notes in the home page, make sure to check it.

Keep checking this main post to see the new added features.

I'll add the following features:
- Add filtering for the all users table.
- Adding profile page for each user, which contains links for all problems he solved.
- Adding some statistics for each user, for example the languages he used to solved the problem, his average number of solved problems per contest, how many times he solved a problem for each level, and more information.
- The ability to compare to users, by merging their graphs together, or counting how many number solved by one of them while the other one failed to solve it.

If you have any suggestion or a feature you wish, feel free to ask for it in this post, and I'll do my best to make all requested features (if I can).

Hope you will find it useful.

Thanks!

Some facts from the all users table:
1- A_A_Lunyov failed in only one problem out of 70 submitted problems.
2- Egor submitted 190 problems.
3- Egor solved 163 problems.
4- Egor is second in the rating and contribution.

~~I think that there is no interest in it without sorting.~~

Also very important stats are: min rating, max rating, worst/best contest(i.e. when lost/get most points), worst/best position and all of that stats could be easily retrieved from profile.

What do you mean by without sorting? You can sort the table by clicking on the header of any column.
And I'll add your requested stats, thanks for your suggestion.

Sorry, that's stupid WebKit, doing O(n²) selection algorithm to sort tables.

Egor	14 лет назад, # ^ \| 0 Hacks stat would be very interesting → Ответить

It's added now. But I'm wondering, is your number of successful hacks correct?
As there is a very big margin between you and the second maximum number of successful hacks.

Probably you count also submits from upsolving and unrated for participant events. It's not right. I have just checked that I have solved all the problems that I have submitted on rated for me events (even for old ACM format contests where it's not critical). And I haven't any fail on contests under the new system.

This only problem is the problem C from the contest with ID 39. Also I have failed on problem G that time. But I have solved it later in upsolving. Am I right that if someone will solve all unsolved by him problems in upsolving then he will have 100% in your table?

Actually the only failed problem is problem C in Codeforces Testing Round #1.
I think the notes written in the home page will answer all your questions.

Here are the notes:
1 - The only ignored contests are the 3 team contests.
2 - Each contestant is considered official even if he is out of competition.
3 - Normal contest and Div 2 contest are considered the same.
4 - The tried and solved problem counts are for the submissions happened during any online contest, even it's unrated.

Really Good :D

Соревнования, в которых мы учавствуем вне конкурса, также учитываются.

k-va	14 лет назад, # ^ \| 0 В задачах учитываются, а в контестах, видимо, нет → Ответить

Да, скорее всего вы правы.

Egor	14 лет назад, # ^ \| +1 Да, я такой. Сам выдумываю задачки и сдаю их :) → Ответить

Sorry, it's fixed now.

Really liked it.

Rubanenko

great job, man!it's rlly interesting to look through such statistic) thank u:)

Fefer_Ivan

Grate job!

First request is to split tables into several pages. Or make header visible always because it is difficult to keep in mind so many column names.

Thank you.

Ripatti

I want some pagination too.

Because of js and my slow PC, I can't sort a table. :(

But it's great, thank you!

Also, maybe it'll be good to make a checkbox, that toggle on/off unrated contest.

Some interesting stats (at least, interesting for me), like at TopCoder:

highest point total in a round; most matches in top3, in top10, in top50; most successful challenges in a single match.

My number of unsuccessful hacks is wrong: it shows 1, but it must be about 10. There are more than 1 unsuccessful hack on each of the latest two contests.

I've just updated the data after the last contest, and I think before the last contest 1 unsuccessful hack was correct.
Now you have 4 unsuccessful hacks, if you think it's still wrong please tell me which contests you did these uncounted hacks.

I think it will be good if you add filtering by country

I had few problems in doing this:

1- It's optional for the user to write his country. (It should be mandatory)

2- The user will write the country in text box, then we can see two different countries "USA" and "United States of America", and maybe more than two. (It should be drop down list)

3- In each profile below the username, there is this string "FirstName LastName, Country, City". And any of these could be missing, so it may be "Country, City" or "FirstName LastName, Country". So I can't easily detect what is the country. (The country should be a constant field below the rating and contribution)
