Codeforces Round #639: the round is rescheduled
By MikeMirzayanov, 5 years ago, In English

Hello, Codeforces!

Unfortunately, I report that I decided to reschedule this round. I'm afraid that something might go wrong. Some strange database behavior has appeared, which leads to slow operation in completely unexpected places (it never was and should not be). I will work hard to fix it. My recent tests show that this can dramatically increase judging time (and leads to a huge queue). I don't want to risk the efforts of the writer, the coordinator, testers, and your time. Sorry about it, I was trying to fix it for many hours but I need more time. Hope it will be a great round!

Mike.

UPD 1: I temporarily rescheduled it on May, 6. But I'll discuss the date with the writer and coordinator and reschedule it again to the date they want.

UPD 2: Monogon approved that May/06/2020 17:35 (Moscow time) is good new date and time for the round. See you in 3 days!

UPD 3: It seems I've fixed the issue. It turned that it was connected with week ago incident. Now it is 4 AM and time to sleep.

    Like a person is all ready with all the pen and paper stuff, and page reloads:

    "Round has been rescheduled!"

    That's disappointing!

    But yeah! Happy fixing. Hoping this get fixed soon and the round is preponed(pardon!) again.

      it's ok to postpone it instead of doing unrated round.

        It is, indeed. We'd rather wait for a good contest, than wait in a judging queue. I must say, really commendable on Mike's part to take a timely decision and then work so hard in fixing the problem as soon as possible. Really impressive how dedicated he is.

    a delayed round much better than a techically bad round, if things went wrong during contest that would have created more problems, but still hoping the delay is shorter than 3 days

      This is actually an interesting topic for debate. Some say your sense of humor increases because of your rating others say that competitive programming is a huge joke so we are essentially practicing comedy. I mean just take look at Xellos the guy is a walking meme took him years of practice to get to that.

        My competitive programming is a huge joke, yeah. That's what 4chan does, it induces a no-fucks-given sense of humour in people. After all, when someone calls you a faggot for the 1000th time, you worry less whether people will find you funny/smart and just go with what you want.

    +1, I would strongly prefer to know about this half an hour ago. I wouldn't waste any time then, and I'm sure it's similar for many other people. Still, moving a round even a second before the start is better than having a bad round.

Ah, it's ok. It affected only 20,000 people, not a big deal.

Didn't you think about spending 125000$ on hiring a team of infrastructure engineers, instead of struggling with bugs, DDOS attacks, 403, 404, server crashes, and electricity problems and apologizing for that all the time?

    yeah, feeling really bad for those 20k people who today were denied a service which they have been using freely using for years. I think mike is way too generous in apologising for issues like these. He could easily say(and he wouldn't be a bit wrong in doing so) "just fuck off you 20k people if you don't like my free service"

      Its quite possible that Mike and team gets some monetary profit from the site.
      Do you think that companies/organisations would sponsor the site if there were no participants ?

      Have you heard about the term "responsibility"?
      It's 2020 now, all services on the internet are free, but it doesn't mean that administration is not responsible for providing quality services for users.

      Another thing is that Codeforces used to be Mike's personal sandbox, however, it's not that anymore since the day he accepted sponsorship from Telegram and launched a crowdfunding campaign. Now he is responsible for providing quality services to those [companies and people] who paid him money. Also, he has to respect users in order to expect respect from us back.

      I'm not blaming him for bugs or anything, I'm blaming him for being too selfish and continuing to run such a large platform on his own. Usually, a couple of large failures is enough to understand that something should be changed globally, however, for Mike it's not enough even dozens of them.

    Then I think you would have to pay 100$/month to be a premium user to participate in the contests or just watch the standings as a free user. Be thankful that you are getting such quality contests for free and without annoying ads. If they use the whole money for hiring a team then who will make problems for free?

      For what? FYI Telegram covers all the expenses for paying to problem setters.
      Moreover, there are several other online CP platforms that work properly, provide the same services for free, and don't launch any crowdfunding. How do they manage to do that? Maybe they have better management?

    How much do you think the work of a decent software engineer costs?

    Moreover, there's already a team of (I guess, mostly) students who work on Codeforces infrastructure.

      For example, in USA $125K is yearly income of one decent software engineer, not of a team. Also, Codeforces doesn't start cowdfounding every year and have other expenses than only website infrastructure.

    What are you upset about? It's a free service being provided. Stop being entitled.

    You're making a faulty assumption that websites with more funds necessarily perform better but arguably the second most popular CP website (CodeChef) has a massive parent company but still glitches out during almost every short contest. (And even that is not such a big deal)

    Plus, Mike specifically posted that they have been working on the bug for some time and he just doesn't want to risk wasting the efforts of the contest makers.

    Happy fixing.

This may be a coincidence, but tomorrow will be the first day students and pupil come back to school in Vietnam. If the contest starts, we have to decide between stay awake until 12AM(GMT+7) or go to sleep. So I think the positive part is, that we could take a nice sleep today before go to school. Anyway, hope the bug will be fix soon, and I can stay awake the day this contest begins <3

Can codeforces make more races before 21:00?
