По многочисленным заявкам на тему "блог сборной России на ioi-2013" попробую написать хоть что-нибудь. В этом году я приехал как гость, поэтому в основных моментах моя программа отличается от программы участников. Например, в то время, как у участников был пробный тур, на котором, по слухам, плохо работали принтеры (впрочем, вы помните хотя бы одно место, где они хорошо работали с первого раза? ;), я ездил на экскурсию в Lone Pine Koala Sanctuary, в котором представлены некоторые виды австралийских (и не только), животных, например следующие: 
В целом Австралия и Брисбен производят довольно приятное впечатление:
Из негативных моментов можно отметить то, что иногда наблюдаются задержки мероприятий (например, сейчас мы сидим в ожидании начала открытия):
А также не очень большой выбор еды (особенно мяса — видимо, австралийцы в основном вегетарианцы :).
Зато местные очень приветливые и всегда рады помочь.
А вот ещё фотка сборной. Ребята приехали на несколько дней раньше, и уже успели акклиматизироваться :) Пожелаем им успехов, первый тур пройдёт уже завтра утром (в 8 утра по местному времени)!
Brisbane, Australia looks really good! Will Taiwan look as good? :s
I like this kangourou so much
Do you have any information about the online scoreboard?
We are waiting for it too. This year contest and place for spectators are far enough, so we just don't know if contest have already started. It's not too many information here. :(
In the meantime there is a live stream http://ioireporter.com.au/
Very ridiculous stream -_-
I don't even think this stream is live ...
And it also has a lot of delay and doesn't provide any confident information about the competition ... I just saw some interviews.
I think it's live, but they are alternately looping the same videos and sometimes doing interviews. They said they are currently working on getting the scoreboard online.
Ok, then I will keep searching.
Please post here if you find any usefull links, I'll do as well :)
Thanks!

IT WORKS !!!
Only timer works.
I'm getting "An error occurred while loading the data. Check your connection and reload the page.".
I am one of participants.
I submitted many times on second and third task, but I couldn't get the feedback over 1 hours...
And the judge queue is still busy, so the analysis may be postponed to tomorrow... I want to know my results...
That sounds horrible ... maybe it should be unrated ... )
I mean, even if the problem itself is fine, the endless waiting queue'll influence each person differently. It shouldn't happend in such a important contest.
Some leaders did have scary ideas like this :D But it would be unfair to the competitors who tried to cope with the system for a long time, so I'm sure it won't happen.
Some more accurate info: Around an hour after the contest started, crazy shit started happening. Some submissions were apparently skipped by the judging system, and those that weren't took very long to evaluate. The organizers eventually fixed the problem, but a large queue of submissions piled up in the meantime and it was impossible to test them all before the end of the contest (which was extended by half an hour, so it was 5.5 hrs in fact). The last submissions to be tested were probably those submitted 1.5-2 hrs before the end of the contest.
It was a poor combination of tasks and judging system. Task 'wombats' had a 20s time limit, so testing just a single submission took too long. Task 'artclass', on the other hand, used actual paintings, so it was pretty much impossible to generate your own test cases (unless you're a painter :D), and the samples didn't contain enough information for solving the task for full 100pts — you needed to test your program by actually submitting it (the author's solution needed 5 submissions to the contest system until it got a full score, too :D). It would, although with some difficulty, be all right... had no system error happened.
I would hyperbolize somewhat here, but what if there is a rowing contest and suddenly all the water from the channel disappears. Would it be unfair to cancel results to those who tried to cope (i. e. run with boat)?
The main reason for why I'm against cancelling day 1 is that from the results, you'd see how many people got a lot of points (top score was 287, I think). So you could add "and actually reached the goal while running with the boat" :D
Day 2 went without serious trouble, at least. The contest was delayed significantly because one of the task statements was updated shortly before the contest and it had to be re-uploaded on the contest machines, but the feedback was working fast. And some results sure are surprising! (BTW I wonder why the live scoreboard stopped working...)
maby it's finally starting http://live.ioi2013.org/Ranking.html
Can we have the problems for Day 2?
Do you mean tasks?
If you want to see problems — there will be lots of them today. You can see them anywhere.
Yes I mean the tasks.
Task statements are here:

YuukaKazami got AK on day2 and became rank 1 :) Congratulations!
Finally, IGM proved herself. Congratulations!

I'm just courious, but in this page YuukaKazami doesn't look like as a girl :)
hos.lyric does look like a girl :)
My result was awful!! I took many hours on "game" by using KD tree,which got TLE in special cases. by the way, KD-tree solution passed by inserting only one constant optimization!!! but I don't mind it because even if I'd solved that, I couldn't have gotten GOLD MEDAL ToT
I mean that getting a gold medal is very difficult even if you're a redcoder both in CF and TC.
Oh man you're gold medalist in APIO 2013 which had problems very harder than IOI 2013.
I think if you worked hard you could got the gold medal
yep;I believe so. But working hard at IOI was difficult to me...sigh...
thank you havaliza!
