I take the pleasure in introducing you to Databread.
DataBread is a platform where you can see an aggregate or generalised form of your ratings from major Competitive Programming websites at one place. These currently include CodeForces, CodeChef, HackerRank, HackerEarth and TopCoder.
The rating system has been completely revamped for less discrepancy (since the previous version).
All those who are already registered can update their TopCoder profiles here.
Since, SPOJ does not have any contest ratings and users could also take help from tons of SPOJ forums available while submitting the practice problems there was no point in taking account of SPOJ ratings there.
The LeaderBoard shows the users registered on this site, here you can find their Ranks, DataBread Ratings and Institution and Country name.
The LeaderBoard can be filtered according to your Institution or Country name, which makes it easy to Find your friends over there.
Also the LeaderBoard now shows the changes in your rating.
2. User Profile Page
The User Profile Page has been completely revamped since the previous version.
Apart from the Usernames and Ratings It now also shows a pie chart showing the percentage of your performances taken while calculating the final ratings. Note that only your highest ratings are taken into account.
There is also a graph showing user's last 6 performance updates.
3. User Search Page
Now you can input the Username or the Name of some user in the search box and see the available users with matching the query easily.
How To Register
... and done.
Looking forward to see you on the LeaderBoard.
Have some great suggestions or found some bugs, just leave in comments below.
Thank You :)

Let me clear it once and for all :)
So, SPOJ is more like a coding practice site. It does not have anything to do if someone is a great coder or not.

@vijju123 thanks for asking to answer :)
For all 5 different websites firstly I have used Standard Scaling to Scale all different ratings to a single scale.
Then I have only taken those ratings into account where you are rated highest (more than the average).

Those updates are cool but why has SPOJ been removed? I guess it is a major competitive programming site!
answered 31 Mar, 19:33
BTW, I wanted to ask, How to do you calculate Databreak rating?
Does it consider rating of all 5 sites? Or only best 2-3? (Cause in my pie chart it only shows codechef and hackerrank).
Also, is calculation of ratings a simple average/weighed mean or some other mathematical formula?

Does Anyone have any ideas on how to make the rating system better, I mean there seem to be a lot of problems on directly using standard scaling!
So If anyone can come up with some better idea then that would be really helpful.
