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://codeforces.me/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.
Is it rated ?
UPD: I have poor English so please Help.
UPD: @mikemirzayanov please highlight unrated. It is hard to notice it.
In the post is clearly said that is unrated.
It will be unrated round.
In this round you can see CodeForces new updates: Hacking,system testing And so on...
Hit CTRL+F type "rated" keep hitting Enter until you see a word containing "rated" inside the post. Now you know if it is rated or unrated.
it's sorrowful thet the contest is unrated
It (UPD)**DOES NOT** overlap with COCI Contest #4. XD
COCI Contest #4 will be held on 19 January.This does not overlaps with any of the CodeForces round.
Thanx dude. I thought it was today. :DDDDDDD
Hi I suppose there is a bug in the system: user "Enchom" is shown twice in the registerant list of the CF testing round #5.
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 :)
hey why did you copy the sgu's 101 problem for the contest?? isn't there any creativity for a problem??!
"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 the system allows participants to hack unlocked solutions.
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.
About the realtime update that is mentioned in the post..it doesn't seem that is realtime , at least to me.
Can you please share the library you used for websockets? Or did you implement your own?
sockjs
does standings now update automatically as well?
turorials??
TUTORIALS???
