Yeah you are right... since I was the only one who used to work in the project it was getting very difficult for me to manage alongside my job work !!

Also cloud instances doesn't come for free :p

Hi macaquedev, this site is not functional anymore.

I have shutdown all backend services which I hosted for this application. It doesn't work anymore.

Only some pages which works on frontend and CF apis will keep working !!

Hey letsJustDoIt, everything will be deleted forever from my end. No need to worry :)

All data concerning each user will be deleted ! Cheers :)

This problem is happening when a problem doesn't have it's rating updated. That's why newer problems were not visible because of no rating assigned to it.

We are looking into this problem and make changes accordingly! Thank you for your patience :).

It's working now ! thanks !

Got the issue, will let u know once the issue is fixed ! Thanks

Hi tahmidarefin, can you please let me know which contest's problems you didnt find in filter ? It'll be helpful for debugging from my end. Thanks !

Hi Ag_Zenitsu, I am glad that CPDojo platform is helping you :) Thank you so much for letting me know !!!

Implementing dark theme will take sometime, but it is in my pipeline. In near future it will surely be implemented.

Peace !

:)

It can't be done so easily though...

For now I am mainly focusing on some AI/ML things to add to the product to help CPers to rank up in much better way...

I've noted this requirement though... will implement it in near future ! :)

Hi chessma, I am working on it. I'll make this live within next 4-5 days. Thank you for your patience !! :D

Hi chessma, this has already been added.... I've added a new tab in 'Contest Info' section for Educational CF rounds. You can check that ! :) cheers !

Hi Ishan, Yeah it means that your next target is Pupil. So, it'll provide you with problems which will be of great value if you solve them and help you the best in reaching Pupil.

Hi everyone,

CPDojo is up now !!

I've deployed a big change for changing whole look and feel of the website.

Also along with these changes I've added a fix in our recommendation system.

Since this is a very large change, pls try it out and let me know if you see any bugs or issues.

Will be helpful if you share your feedbacks and thoughts as well :)

Cheers !

Deploying new changes to CPDojo... it'll be unavailable for sometime...

Will update here once it's up ! Thank you for your patience !

Hi Codeforces community, I have added a big change to problem recommendation algorithm for better and accurate recommendations. Please make sure to check it out :)

Thank you !

it up now !!

Hi all, I am deploying some fixes in the backend code so CPDojo backend will be down for a while ! Thanks for your patience...

Hey invisibleparadox, let me know if you have any issues or concerns. Thanks !

A note to anyone who uses the recommendation system:

It is a tool which will help you to reach the next rating group which you want to achieve, and it is NOT a tool which recommends problem properly if you select your current rating group.

For eg: if you are Specialist, then your next rating group will be Expert and so you should choose Expert (and not your current rating i.e Specialist)

Hope this helps to clarify any doubts that may arise.

Reach out to me in case you need any assistance or want to provide feedback ! Thank you !

Hi Codeforces community, it's been a long since I added any updates to CPDojo.

Many of us struggle a lot while choosing problems for upskilling. So I have created a problemset recommender for suggesting which problem to solve for reaching some particular rating group (eg: Expert, CM, etc)

This is entirely data driven and is built using 40k+ active user's data.

I personally tried this for myself and found out that the recommended problems were overall balanced and if solved diligently it'll definitely help you out...

I just finished this work today (it maybe little unstable). Pls do let me know your thoughts and feedbacks.

It can be found under Recommender section in left-side navbar in cpdojo.com. User has to login using their gmail account to access this recommender feature.

In case of any bugs or errors pls reach out to me. Thank you !

Hi EnDerBeaT, the problem is resolved now ! CPDojo is up and running !

Hi Chessma, I have been trying to give some time to CPDojo too... but due to release work of product in my current company (where I am working as an employee), I am not able to give time to CPDojo. Will implement it surely and let you know once I get time.

Thank you for your patience ! :)

Anyway, as of now, you can just use the date field in problem filter page and give some date which is around 1 month back from now. This way you can get latest problems ! You can use this as a workaround !

Server was down due to payment issues ! Server is up now !

Oh is it ? Can you provide some way to reproduce the same ? it will help us get this issue sorted !

Hi Chessma, as I am busy with my job related work I am not able to give much time for CPDojo. Will let you know once this feature and other bug fixes are done ! Cheers :)

Hi chessma, we have planned to add this feature to cpdojo. Will update you soon :)

Hi d_sqaure, we have noted these changes... will work on this and get it resolved asap ! Cheers :)

Hi d_sqaure, this maybe a product defect. Can you please give me the steps to reproduce this defect ? We'll try to get it resolved asap !

Thanks buddy :)

This can be done, but we felt that this sorting (sorting by rating) may defeat the purpose of searching for problems based on keywords. Anyways, we have added it to our list and will be implemented in near future !

Hi chessma, the search functionality is pretty flexible. You can type text as you want to search... it is not substring matching search so you can add multiple words and context while searching.

Hi CF community, I've added a functionality to search for problem statement based on certain specific keywords. Here we have actually prioritized match of problem statements with querying keywords, so it won't be sorted by rating, but is sorted on the basis of best match.

You can check it out from search button on the left nav-bar ! Cheers :)

Hi Chessma, this feature (problem-statement search based on keywords) is currently live now ! cheers :)

Hi chessma, 80% work is done for problem statement search functionality. Will try to make it live asap !

Maybe we can implement searching for contests as well... need to check this !

Hi chessma, this feature is currently under development. Will try to get this to production within 2 weeks. Cheers :)

Hi chessma, I've added this to my task list. Will update here once done ! Cheers ! :)

CPDojo went down because of SSL certificate issues... Is up and running now !

This feature is now live. :) cheers !

---- New update ---

You can now exclude older problems by adding date in problem filter section. After adding a particular date all problems created before that date will not be added in the query results.

Hi Anchord, the feature which you have suggested is kind of complex... but yeah, will think of some way to implement it in near future !

Thank you for your valuable suggestion ! :) cheers !

Hi chessma, this feature is live now ! cheers :)

Noted this requirement... will implement it asap ! cheers :)

this one is live now ! :)

---- New update ----

Added provision to see current week's, month's and year's solved problems.

Hi chessma, I checked this from my end... it seems to be working... can you please check once ?

PS: Actually, for highlighting solved problems I am using codeforces apis. So if CF apis are down for some reason, it won't be marked green.

Hope this gives you some clarity.

Cheers :)

Glad to hear that :)

Done the changes, now cpdojo should not go down any sooner :)

Due to upvote feature (which was released recently) CPU usage is getting too high, leading to VM going down.

So disabling this feature temporarily.

Thank you for your patience... !

Upgraded CPDojo VM for better performance.

Hi theali, I just tried using your handle. I can see your details. Did you press enter after adding your handle in User Details.

Hi theali, can I please know which user's details you are searching for ?

From past few days (after including the upvote feature), I am observing that my VM instance is getting overloaded (and bcoz of this the site goes down). I am monitoring this issue closely. I will work on it's optimization and try to make sure the downtime decreases considerably.

The site is up and running now.

Thank you for your patience !

Hi red24, I've noted this change! I will add this feature to the platform in near future. Cheers :)

Sure... I will work on this one... maybe in some days I'll release these features along with some bug-fixes and optimizations.

Cheers :)

awesome !

will consider doing this in near future ! cheers :)

is this resolved ?

For this I was thinking about adding some feature to add additional tags. But I am afraid that some people might spam any tags as they want which can cause undesired results. But anyways will think about some way to implement it in near future....

Hi Chessma, I tried doing this, and yes I am getting problems related to the filter.

Some eg are : 455/A — Boredom 698/A — Vacations 474/D — Flowers

Can you please check if other filters are working fine...

Also, can you please check in your chrome's network tab... whether some apis are failing or are we getting some console errors.

Ohh, it's a bit weird issue... Can you please try opening cpdojo.com using incognito mode ?

Wanted to check if it works there...

made some changes, it should work now ! :)

I have added a feature to filter out user solves. You can check it under User details >> User solves >> Apply filter button.

Hi Chessma, is it still not working ?

Also if you don't mind, can you tell me which OS and browser you are using ?

Because I tried it on windows and mac OS with chrome browser, it is working.

Page loading may be a bit slow because of too many CSS style, I am working on optimizing it.

Please do let me know...

It is up again... ! thank you for your patience :)

Due to some technical issues CPDojo apis have stopped working... will fix it and let you know... thank you for your patience :)

--- New update ---

-- Added Dark theme.

If anyone finds any bugs pls do let me know ! thank you !!!

Note: you can change theme from top-right button (before login button)

Dark mode is live now ! :) cheers

Thank you kingmessi_FAN ! I am glad that it's helping you and you find it good ! :)

Hi red24, thank you for your valueable suggestion :). I have added this to development plan. Will make it live along with other features.

If anyone has some other interesting idea which can be integrated into CPDojo pls do let me know ! :)

Hi Chessma, currently due to workload I am not able to spend time on building this feature. I will try to make this feature available asap. :)

Hi chessma, both problem filter and user details section use different data sources. Also, Problem filter finds all problems irrespective of user/handle, i.e all problems that fit in filtering criteria (ofc limited by number of records). So I thought it would be inappropriate to add it in problem filter section.

But I can see that filtering is needed for user's solves tab too... So yeah I will think of some way to add it to UI.

Thank you for your valuable feedback :)

---- New update ----

Added table so that you can view some user's all solved problems in a given time range.

Hi Chessma, this feature is live now... You can find it under User Details >>> User's solves tab... Cheers :)

Hi chessma, I have added this feature to development plan. Will notify you once it is live... cheers :)

Hi adnan_toky, these features are live now :)

--- New updates ---

Contest filter has been added, where you can search for contests for practicing. It will show up all contests for which you haven't solved/attempted any problems.

You can also add group members (but only upto 5 members)

Hi amansingh81757, let me give you little bit of background.

Sometimes we solve a particular problem that may require some different kind of thinking around the problem, or some interesting observation that might help to solve similar problems when we encounter them again. In short problems/way of thinking/observation that are really worth noting down and reviewing.

At such a time that user can upvote that particular problem and his/her upvote will contribute to the problem's learning index.

In short, it is recommended to solve problems with high LI, because it is recommended by many CPers. As of now LI for problems is less, but as time goes on and more and more people begin to upvote genuinely, it will start pointing us to right problems in a long run :)

These changes are live now :) !!

Deployment complete.... changes are live now

---- New updates 1 ---------------------------------------------------------------------------------------------------------

1. Added sorting on columns — ratings and number of solves --> Tap on table header for that column and it will be sorted. For now supporting only ascending sorting of ratings column and descending sorting for number of solves column.

When you sort ratings column, problems will be sorted first by ratings (in asc order) and then tie is broken by sorting number of solves (in desc order)

When you sort number of solves column, problems will be sorted first by number of solves(in desc order) and then tie is broken by sorting ratings (in asc order)

---- New updates 2 ----------------------------------------------------------------------------------------------------------

1. Added a checkbox (must include selected tags) to ensure that the problems which you get will have all tags which you have selected. This is helpful in case you need to get problems having dp and trees both together (for topic like dp on trees).

UPDATE: forgot to build the backend before deploying... now all features will be working :)

Hi Chessma, this feature is under development now... along with sorting over table feature... they will be live within next 24 hours! Thank you for your patience !

Thank you chessma for your valuable feedback. I have planned to add sorting to table. In some days it will be implemented. Cheers :)

Site is up and running now :)

Please do let me know if it goes down again... probably need to get a new VM...

Due to latest deployment, some issue is slowing down the VM... I am working on it (it will be down for sometime). Sorry for the inconvenience. Will update here once the setup is up and running.

Hi chessma, this change is live now... ! cheers :)

New updates added :

-- problems per page can be changed now — [10, 20, 50, 100] problems per page

-- ratings is visible in table (you can definitely hide it by checking the checkbox saying — hide ratings)

-- little bit improvements in UX of tables.

Hi chessma, these changes are in their development stages. I will notify you once they are done ! Cheers !

New updates to cpdojo:

I have added upvote system for problems. Once when we find a problem really interesting and think that someone might get some value when they solve a particular problem, at this case, we can upvote a particular problem. This will contribute to it's Learning Index.

Thus it will help users to find better quality problems even though they are using some different kind of filter.

You can get filtered results sorted in descending order of Learning Index. (You will find a checkbox right below min-max number of solves)

You need to login first in order to make an upvote.

I really think that this upvote system will help CPers in a long run.

Please let me know your thoughts. Cheers :) Also, since this is a big change from my end, there may be some bugs or performance issue. Please let me know if you encounter any kind of bugs / inconvenience.

Hi adnan_toky, thank you for your valuable feedback. I have noted down these changes. Will implement and add these changes to the platform in near future.

Cheers :)

Hi Chessma, I am glad that these changes have helped you :).

I have added these new changes which you have requested to my task list. Will begin working on it once I am free.

Cheers :)

Hi Chessma, I have added a screenshot of exclusion filter in the blog...

When you click at the checkbox there will be 3 states now -- Select this particular type (shown by tick) -- Exclude this particular type (shown by — sign) -- No need to include this tag compulsorily, but it is OK if it is present (shown by empty checkbox)

If the issue still persists pls do let me know.
