Codeforces 10 years!
Immortal list of supporters

It seems that just yesterday I was developing the basic Codeforces functionality and preparing the first round. In fact, 10 years have passed since then. Ten years!

Codeforces celebrates an unusual birthday - 10 years is a symbolic and important date. More than 700 rounds and open competitions have been hosted, the number of problems in the archive is close to 6000, more than 60 million submissions have been judged. Codeforces infrastructure is widely used in the world for making local competitions, training events, preparing problems for various contests.

Thanks to all the enthusiasts who help Codeforces: we are many! These are not only problem writers and testers, round coordinators, developers, authors of clever posts and comments. Friendly companies do not refuse to help, true friends are always there when the moment requires it, regardless of who and where is located geographically.

I appeal to the entire Codeforces audience to support the platform by participating in the anniversary crowdfunding campaign. Your donation will be a contribution to the future of Codeforces, will help its development and work. We need resources to continue to host rounds, not to stop developing, to innovate and to maintain the existing infrastructure.

With thanks,
Codeforces Founder and CEO
Mike Mirzayanov

      You can sign up for a PayPal account, and then bind the ordinary UnionPay card to pay. Even though it's a bit cumbersome, we can still contribute to codeforces.

      Without Alipay, Chinese can't support codeforces easily. Because most of Chinese students hardly ever use other way to pal. @MikeMirzayanov

Congratulations Mike and whole Codeforces team!

I have an unrelated question regarding to online card payments. I decided to support with $45 and used card tied to my Polish account whose currency is USD to not lose on the conversion rates. PayPal told me that the amount it will take from my account is ~183zł (instead of $45). I was puzzled and afraid I will lose on the double conversion, but out of curiosity I decided to continue and indeed on my bank account I see that I wanted to pay ~183zł which my bank calculated to be worth $50.86, so indeed I lost twice on the conversion rates instead of intended zero times. Anyone can explain that?

    PayPal allows you to choose desired currency for transaction. But by default it tries to convert the price to your country's currency by itself (and PayPal's exchange rate is usually worse than in the bank) ¯\_(ツ)_/¯

Thanks to Mike and to you ALL for the great Codeforces.com platform, Polygon testing system, and more importantly for the great, ingenious, interesting, educational and fun problems and solutions. We are effectively the Ruling Scientific Authority on Computer Science and Informatics; of course, other researchers, like some of you are, in usual Universities can also teach and make more speculative/less practical discoveries. But any Div1 coder (and in my view most of the Expert ones — above 1700 in my view) {max rating, not current}, can peer review and / or understand any computer scientific idea. If it makes sense to us.. it is worthy. If it doesn't, it is probably not.. however even then, some may simply have not been explored deep enough for someone other than the author to understand their potential relevance.

Thanks again, Mike and Codeforces. I dedicate these to articles of mine on ResearchGate.net to YOU:

1) https://www.researchgate.net/publication/337170731_Towards_Solving_NP-Complete_and_Other_Hard_Problems_Efficiently_in_Practice. 2) https://www.researchgate.net/publication/339376899_Hiding_Data_in_Plain_Sight_Towards_Provably_Unbreakable_Encryption_with_Short_Secret_Keys_and_One-Way_Functions.

Congratulations Codeforces! But your attractiveness is becoming lower because of usual too strong pretests which makes hacking impossible or rare. Also then it is almost no difference between normal and edu rounds. I hope for more balanced rounds == solving > hacking, not solving >> hacking. Best wishes!
