Codeforces Testing Round #5
By MikeMirzayanov, 12 years ago, translation, In English

Codeforces Testing Round 5 starts on Jan. 12, 2013, 15:00 (UTC). Our goal is to test the platform after recent improvements. You may notice that we've improved real realtime status. You may visit (problemset status)(http://mirror.codeforces.com/problemset/status) and find that it updates automatically without page reloadings. It uses modern web realtime technologies like websockets and so on. For sure, no server polling!

Also we've updated server software and built Codeforces with Java 7.

I invite you to take part in the round. It will be Div. 2 + unofficials from Div. 1. It will contain three obsolescent problems. But I think it will be interesting for many of you. The problems contain very weak pretests to force more hacks. It will be unrated round.

Many thanks to participants!

P.S. As it is testing round, we do not guarantee stable work and so on.

    I registered once and then the register button was still there, telling me i'm not registered even though i got a small "Successful registration" notice in the corner of my screen, so i clicked register once more and it worked the second time, didn't know i'm registered twice though :P

    P.S Unregistered once so everything is ok now, i'm registered just once :)

    . It will contain three obsolescent problems.

    It's testing round, so spend good unused problems it's bad idea

    I am sorry to tell you, that it's perfectly OK. You can hack anyone. But you can only hack if you have a locked solution for this task.

Can you please share the library you used for websockets? Or did you implement your own?
