CODECHEF Attendance Tool

Hey There Guys,

Hope You all are having a good time. I want to present you another tool which can show you your attendance in CodeChef.

This is especially useful for those who want to check their Attendance for the 100% Attendance prize category recently introduced to CodeChef.

Not Writing any further (need to study for exams :p)

Please leave your comments below.

MAJOR CHANGES

I literally wrote the entire code for the site again from scratch today morning (LITERALLY).

There were mainly 2 problems :

  1. The MARCH COOK OFF getting unrated, so even if some one participated in that, it was still showing that the person didn't take part.

  2. Even if a person did not solve any problem correctly and their rating changes (might happen if someone submits but doesn't get AC in any of their submissions) will still be shown as present.

These 2 problems were there because I was scraping the change of ratings instead of the number of Problems solved (which was actually needed).

But no worries people, It's been fixed now.

Also as I already mentioned that I wrote the entire code again (major parts), there might be some new bugs waiting for me to fix. So please Let me Know. Peace.

Here's The Link to the site.

FaceBook Page to stay updated :)


Thank You.

The only confusion I have presently is whether I should remove that CodeChef Logo or not(Cause it's unofficial :p).

I will remove it if they ask me to.

Regarding logo, send them a mail. It would be safe that you "informed them", instead of using it until they retaliate. Cause logos and stuff...its usually best to take permission to avoid unnecessary hassle.

And lmao, i knew you will bring something like this up when i saw you thanking for idea. :p

Hey mate, I think you search for certain keywords such as "FEB14" in the page of the person that's why it's showing that I gave feb14 long challenge even though I haven't but I have solved a problem named "LFEB14B". Anyways, awesome work!!

Hey! How did you add those random quotes in the end of that source code :D

I checked it on your github link too but found no evidences how that occurs? Seriously did you not upload that on github or is it something deeper which I can't figure out?

and BTW congrats. I just saw that "saakhshaat" Codechef responded on this post :P

(22 May '17, 22:12) shivamiet1★

Reminds me that codechef was also thinking of releasing an app?

(22 May '17, 23:21) vijju123 ♦♦5★

I searched for that post after reading your comment. Hope for the best.

(23 May '17, 06:41) shraeyas3★

Can you please reply to my query above?

Just wanted to know how to make those quotes change.

(23 May '17, 15:01) shivamiet1★

It's simple buddy :p

If you know even a little bit about web development and languages then you can figure out how that works.

Just try to think about it for once :)

(23 May '17, 17:44) shraeyas3★

I couldn't. Please tell me how -_-

(24 May '17, 16:54) shivamiet1★

There are tons of methods, the easiest way could be...

Just take an array, add few sentences in it (i.e. strings) and access the array elements using a random number generator (use it as index for the array).

(25 May '17, 08:38) shraeyas3★

Ok. Thank you so much. So now I know. :)

Can you give me some tips to excel in Competitive Programming?

(25 May '17, 18:26) shivamiet1★

That is something I myself am trying to figure out :P

(25 May '17, 18:28) shraeyas3★

There's another bug and not really a bug but kind of an improvement.

For example sometimes codechef gives 503 error and in that case your tool shows that the person is not present in any of the contests. So I was just saying if you show some error message in that case then that would be better.

:)

(31 May '17, 22:01) shivamiet1★

Please fix the above problem also.

(04 Jun '17, 09:26) shivamiet1★

If I am not wrong I guess this error (503) now doesn't come on Codechef now?

(06 Jun '17, 12:55) shraeyas3★

why can't I view attendance before 2014?

(10 Jun '17, 13:01) shivamiet1★

Since Lunchtimes were started from June 2013 so I thought there was not much need to show attendance before that.

(10 Jun '17, 17:30) shraeyas3★

Ok ok. What about the app?

(10 Jun '17, 17:34) shivamiet1★

Currently there doesn't seem for any need of an app for this purpose. Simply having an app for viewing one's attendance is not enough, then it should also contain features like contest notification and all, only then it would be useful. But such apps already exist, so clearly an app for simply this purpose is not of much use.

(10 Jun '17, 17:37) shraeyas3★

Ok ok. I see. Thanks,

:)

For the past couple of days I have been trying to check my attendance but it shows invalid username. Have tried with a bunch of different usernames and all the same error message.

It has been introduced in March, so from March 2017 onwards 12 months in a row full attendance (in Long, Short and Lunch Time) will fetch you 1000 laddus.

Well I did attend April Long Challenge and Cook-Off and some other contests previously but its showing that I've attended not even a single contest since I've logged in. Please look into it.

@shaeyas your website(tool) has a page-view counter which doesn't count unique page views ( i think you know this ) . it would be better if you get a unique page-view counter up and running . Great work BTW!

It will now show a warning sign in case of any miscellaneous contests (unrated or cancelled).

If I come across any better solution to this I will add it later.

Also if there is any other contest which was cancelled or something then you all can post into comments. It will be added to the exceptions.

I only know about two such contests viz. March Cook-Off and May Lunchtime so they have been added.

Btw I was also present in oct17. You can see my rating fall. But since I was not able to solve any question. So Your tool is showing me absent. alt text

Hey @shraeyas

Nice Tool.
I guess u missed one thing. Problem setting panel is also deemed to be participating in the contest, for the purpose of attendence, as i know.

For example, @vijju123 was editorialist for APRIL18, but he is shown to have not participated in APRIL18. (Wasnt stalking. Just thought of this possibility and searched for the Master Chef Vijju :D )

@vijju123, you deserve to be kicked out if u participate in a contest where u r editorialist. Cant say fairer than that.

I guess u misread my statement (it wasn't unexpected). Deemed means assumed. U dont have to actually make a submission.

Well done buddy! However, it's sort of an optimisation of counting the contest names in the profile. It would be nice if it would tell the exact time (Eg: Feb Cook Off 2017) When my 100% attendance would be completed. You took it from O(nlogn) to O(n), now take it to O(logn)!

It actually tracks the changes in ratings and then tell us if someone participated or not.

But I will try finding a fix on that, but till then kindly bear with me (need to study for exams too :p ).
