The 100th Round: 100 Codeforces T-shirts!
By MikeMirzayanov, 12 years ago, translation, In English

Hello, everybody.

New Year Holiday is a time of miracles and gifts! Quite by chance the 100th Codeforces round coincided with this wonderful moment.

So, January 4 at 15:00 (UTC) the anniversary Codeforces Round 100 will have place. Yes, we say goodbye to the word Beta in round titles :)

It will be a combined round, that is, participants Div1, Div2 and newcomers will compete with one set of problems. To make it interesting for each participant we plan to expand the round to 6 problems.

The most important thing: the best hundred participants of the 100th round will receive an exclusive Codeforces t-shirt!

Happy new year!
Codeforces Team

It's better to provide some lucky T-shirt for randomized participants, or it's almost impossible for most people to get that valuable gift.

      Yes, I agree. Actually I'm on the way of being better, hope one day I'll be qualified enough for a T-shirt.

Can it be randomized for something like the first 500 contestants ?

    What for? Just imagine: someone will win this contest, and you will get 493th place (it is just an example).
    And you will get the T-Shirt, but winner won't get it. Is it an honest game? No.

    If you think that you must win this T-Shirt then you have 11 days to prepare for this contest. Good luck!

    I don't agree with the randomization at all. If the reason of doing this is  because some people think it's impossible for them to get a t-shirt, so I think the winner of the next TCO should be selected randomly.

    I think we can make another kind of gift (as badges or something like that beside the t-shirt) to be given to other contestants rather than the top 100 to increase the range of winning a gift.

I believe it might exceed 3k participants so be aware of system failing.. :)

Why don't you make 100 t-shirts for div1 and 100 t-shirts for div2 and make them 2 separate contests to increase the probability of winners? (combined contest will not be fair for contestants of div2)

    Then the number of participants in division 2 would increase significantly compared to division 1 (Easier challenging, Easier problem set). And the contest would become a fast-coding-contest instead of a real brain-battle.

    Moreover, why did you say it is "not fair"? Not giving a prize does not mean "unfair" !

    This only gives the contestants in division 2 more motivation for becoming better. I don't think that becoming a top in division 2 easily is more valuable than gaining real knowledge and real experience with other good coders in division 1.

      100% agree with ConanKudo.Moreover if 100 T-shirts are given to Div 2 as well then there is a chance of lots of fake accounts to open in the new year(of those of the Div 1 brilliants)

    If you do not face the challenges head-on, it will take you a long time for becoming better.

      Yes, therefore I ask the admin to allow any div2 coders to register in div1 match.
      (Is it already possible ? )

When I unofficially participated some Div 2 round, I found that Div 2 coders often have better chance to hack since people in their room seem to make more mistakes. So, will it be fair if some people register new IDs to compete in Div 2 rooms? I think rooms should include both Div 1 and Div 2.

    I agree. In the last contest:

    Div1 Hacks - 45 attempts, 19 successes by 345 contestants
    Div2 Hacks - 196 attempts, 115 successes by 1123 contestants
    Successful hacks / contestants = 0.055 (Div1), 0.102 (Div2)
    Moreover, hacks on this problem would require less time than this one.
    (EDIT) I'm sorry, I forgot that the problem set in the round #100 will be shared.
    I didn't change my mind, however - will Div1 coders make this many mistakes in this problem?

    Even though round #100 will be a combined one, I might still create a new account just for that precious T-shirt, if I could compete in a Div2 room (well, now that I posted this, I promise I won't).

      At first, rooms definitely will be joint for all divisions.
      At second, since there will be common problemset - your second argument is void.

        Check some recently combined rounds, 88 and 90. There are separated rooms for div 1 (from room 1) and div 2 (from room 50).

          They wasn't truly combined, just Div1+Div2, but in same contest.
          Completely combined rounds was in Yandex.Algorithm.

Won't the beta be removed from the codeforces logo? Now that finally the first unbetted round is about to be here lets make the logo non-betified as well :)

Hi.

With 2012 being the last year before world's end and all the new codeforces contest comming up, I wondered if there is any plan for an automatically maintained Google Calendar showing us the upcomming Codeforces Events ?

I mean, the "contests" button is not very practical, and the calendar I used to use ( http://codeforces-calendar.appspot.com/ ) is no longer maintained, which saddens me quite a bit =(

Btw, happy new year to everyone =)
