StopStalk: Tool to maintain your algorithmic progress
By raj454raj, history, 9 years ago, In English

Hello guys! I want to present before you an awesome tool StopStalk to keep track of your friends' submissions on various competitive websites(Codeforces, UVa, Timus, Codechef, Spoj, HackerEarth, HackerRank).

And that is just not it. It has a lot of other features —

  1. Streak notifier of your friends

  2. Feel like solving algorithmic problems — Why go to Codeforces and search for a problem? Solve problems from across all the platforms. Search a problem by tag. See which friends have solved that problem and what is the difficulty level of the problem.

  3. Want to solve problems that other coders are solving recently - We got a list of trending problems both globally and also amongst your friends.

  4. A global leaderboard along with a unique rating which includes submissions from all the websites.

  5. Do you forget contests? — We got a list of upcoming contests and an option to remind you 30 mins before the contest starts.

  6. Do you often remember some friend's submission on a particular site and want to view that submission — We got you covered. We have a filter page to find exactly what you want.

  7. If you add a custom friend only you can see his/her submissions. This is useful when one of your friend is not on StopStalk or not accepting your friend request! Though the better method will be to invite him/her on StopStalk. And a lot more!!!

The goal is to keep people motivated in algorithmic programming and solve more and more problems. And yeah we do have a referral program. Just share your StopStalk handle after registering with your friends and ask them to enter while registering.

Also you get these awesome Laptop Stickers for just making friends. Increase your network of friends and enjoy its perks. Stickers will be dispatched on 11th April.

Register now

If you already have start making friends to get more and more stickers.

The code is completely Open Source: Github

Great work man. I found this tool to be really useful, especially the contest reminder. I often intend to write contests but then forget about them as the day goes on. Also, the fact I can see all future contests from all platforms also helps a lot in deciding which ones to write.

Kudos!

Great tool for tracking practice progress.Thank you. Some personal advices: 1.Add tracking for more online judges, like UVa, POJ, HDU, etc.(maybe vjudge.net will be a great reference). 2.Tracking for TopCoder practice (this will be a little bit hard). 3.Anti-cheat and filter out bots. 4.Some problems may appear on various sites, It will be good to merge them into one.This will bring us a great convenience and make that site a hub for full tracking. Hope your great tool be greater.

Hello raj454raj I find the website extremely cool & I have something to suggest

Problem a lot of coders face:

  • Sometimes the editorials of some problems are not so good or are too tough to understand for some coders.
  • Sometimes the codes of fellow coders are also too complex and are also very tough to understand.

One of the possible solution using your website:

Give a platform in your website where we can write a custom editorial and if possible also add a feature in which we can contribute our properly documented solution in all the possible languages.

I think if this feature can be enabled it will help a lots of struggling coders and also those coders who belong to the remote locations without proper instructors.

What's your view on this ?

    Hey fiter, It's not just about stalking, we definitely started with just that as the end goal but we have evolved to a tremendous frontier of user analytics that can be used to improve exactly where we need to. Stalking on StopStalk is not just stalking but also a sense of hope that you will also become like your friend if you follow a similar path. If your friends are not that great competitive programming then you can always follow any of the great coders and see how they progressed :)

Few important and cool updates on the site -

  1. As many of you guys requested about the ambiguity of the icons in the navbar — we have cleared the icon clutter from the navbar — Video
  2. We have added a small button on the leaderboard page as well as on the user profile page to view the list of custom users by a user. What you can do with that is you can simply add them to your custom user list ;) — saves you from the pain of entering the handles again.
  3. We have reached 5100+ users from universities across the world (Last year we were 1500 at this time)

Thank you guys for your love and support, we will keep on doing the great work and build a tool with all the features that you want :)

Happy Diwali and Happy Coding !

      Thanks for the awesome tool. I sent you a question using contact_us link you provided above. To repeat:

      In my profile page, it seems like there are some differences in the solved count:

      1. CodeChef: 499 fully solved and 11 partially solved VS. 444 (-66 problems)
      2. CodeForces: 3054 VS. 2833 (-221 problems)
      3. SPOJ: 230 VS. 83 (-147 problems)
      4. HackerEarth: 22 VS. 16 (-6 problems)
      5. HackerRank is correct.
      6. UVa: 499 VS. 210 (-289 problems)
      7. Timus: 329 VS. 182 (-147 problems)

      The total number of problems are under-represented by 66+221+147+6+289+147 = 876 problems.

      Could you look into this issue?

      Thank you!

        First of all, thanks a lot for a very positive feedback on multiple things after your exploration of the product — hope you're loving it.

        We have already replied to your feedback over email. In terms of closure of this thread — the difference in counts is because StopStalk only fetches submissions from 1st Jan 2013 and your other submissions were older than that. (Ref)

          Then, I suspect that 876 problems are exactly the ones I solved prior to 01/01/2013. Is that right? It would be awesome if you could go further, to 01/01/2008 (5 years ahead). If you do that, I am sure it will catch all the problems I solved. This is such an awesome tool! Thanks!

    On Codeforces you can hide tags. Just click on problemset and then you'll see 2 options. Hide Solved Questions and Show tags. Unmark it..
