Кажется, еще только вчера я разрабатывал базовую функциональность Codeforces и проводил первый раунд. На самом деле с тех прошло 10 лет. Целых 10 лет!
Codeforces отмечает не обычный день рождения – 10 лет символическая и важная дата. Проведены более 700 раундов и открытых соревнований, количество задач в архиве приближается к 6000, протестировано более 60 миллионов решений. Инфраструктура Codeforces широко в мире пользуются для проведения локальных соревнований, учебных мероприятий, подготовки задач к различным олимпиадам.
Спасибо всем энтузиастам, кто помогает Codeforces – нас много! Это не только авторы и тестеры задач, координаторы раундов, разработчики системы, авторы умных постов и комментариев. Дружественные компании не отказывают с помощью, настоящие друзья всегда рядом, когда того требует момент, независимо кто и где находится географически.
Я обращаюсь ко всей аудитории Codeforces с предложением поддержать платформу, приняв участие в краудфандинг-кампании по случаю юбилея. Ваше пожертвование станет вкладом в будущее Codeforces, поможет его развитию и работе. Нам нужны ресурсы, чтобы продолжать проводить раунды, не останавливаться в разработке, внедрять нововведения и поддерживать существующую инфраструктуру.
С благодарностью,
основатель и руководитель Codeforces
Михаил Мирзаянов

Congratulations! I hope I am the first one! ;)

А вы заметили, что в Майка в Русской версии видео на футболке "Sponsored by Telegram", а в Английской — "Sponsored by Me" :)
Там написано "Supported by Me", в английской версии :)
hey kiddo!

Hey MikeMirzayanov , Why not accept "Alipay",If you do this more Chinese will support codeforces.
wechat XDXD
QQ coin
why QQ wallet = QQ coin
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
I agree. I usually use wechat to pay
Great job
Great work.
CONGRATULATIONS ! , I am the second one :(
Are Are Are, ye sab kar rha hai tu xD
cin>>congratulation;
You should do Cout<<"Congratulations \n";
Lmao! No wonder he is pupil.
And U are unrated lol!!!
I think he means codeforces is geting money as congratulation so "cin>>congratulation" is kinda correct.
Underrated comment of the year
im the fourth ^_^
Brilliant, and thank you team Codeforces for this endeavour you all have taken... Congratulations !!!

You forget that Mike sees into the future. tourist is back on the throne!

You also forget that Mike can't see very far into the future since MiFaFaOvO is the first place now.
Yes, but tourist has the highest rating ever achieved by someone on CodeForces.
Of course codeforces is the most popular online judge for the competitive programmers. Congratulatios Codeforces ! for your amazing 10 years journey.

I hope u are happy by using one of the most confusing date formats :(

Hope to support Alipay and WeChat payment, so that more Chinese people will donate.
In fact, we can use PayPal to bind our bank card.
My love❤️ for competitive programming is just because of Codeforces. Happy birthday and congratulations to the team Codeforces.

What a great news![](/predownloaded/60/69/6069ab7a8cd1b9cf24afee713725625a563fe44b)
раз уж нет комментов от того, кто может это починить -- у меня заработало через paypal
Вероятно, можно задонатить полную сумму, если кошелек идентифицирован и списание именно с него, а не с карты. Или просто сделайте несколько донатов и напишите мне, я их объединю в один с нужной наградой. Спасибо!
Очень на то похоже. У меня, кстати, PayPal тоже в какой-то момент заработал. Кажется, я там зарегистрировался. Видимо, для больших донатов нужно делать какие-то дополнительные действия, что звучит вполне нормально.
Ya! I am cloud
I think codeforces should pay some money(from donations) to poor people.
Congratulations
Congratulations to the best !!!!!
If you accept Alipay, more Chinese student like me will be very glad to support CodeForces. (I give up when I need to sign up a Paypal account.)
Hope that when I get older, I'll be able to support Codeforces and get the badges =)
Happy birthday!
活捉?
你认错了
Happy!
Will we have "Codeforces Delta" by 2030?

Friends, many thanks for the congratulations. I read all of them, they are very inspiring!
:) many thanks to you as well!
здравствуйте, дико извиняюсь — но ожидается ли добавление новых фич на сайте?) я даже не про обновление дизайна, а про то, чтобы добавить немного больше информации в профиле, например — сколько всего успешно пройденных(отправленных) решений, сколько всего попыток, каков процент решенных задач — для тех, кто нигде не участвует, а просто решает задачи для души из архива, может систему рейтинга подразвить, значки разные выдавать или еще что-то из игрового мира)
будет приятная мотивация, чтобы решать больше задач — всегда здорово видеть статистику своих действий
Так вы для души задачи решаете, или вам мотивация нужна?
так это не взаимоисключающие вещи) для души, но приятно же видеть сколько уже ты в целом решил) там в списке попыток даже отсортировать нельзя по статусу, чтобы хоть как-то их самостоятельно подсчитать (или я не нашла, как это сделать)
Тут вы можете увидеть все свои посылки. А тут все мои. Раз уж вы используете PHP, то для вас не составит труда написать простой скрипт, который посчитает количество правильно решенных задач — там есть поле "verdict". Более подробно можете почитать про это здесь.
спасибо!)
I would like to add ETH, BITCOIN or XRP payment form to contribute
Поздравляю КФ!
P.S. В десятом, кажется, классе, меня стали заставлять писать олимпиады, в том числе по информатике. Всех я их, понятное дело, завалил, так как никто, чёрт возьми, никто не говорил мне, как готовиться, а сам догадываться я просто не умею по причине слабых мозгов. Теперь у меня дикий баттхёрт и лютая ненависть ко всему олимпиадному, а также валяющаяся на дне глубочайшего ущелья самооценка. Это не пост с поздравлениями, это крик о помощи, чтобы кто-нибудь пришёл на квартиру и пристрелил меня, пока я совсем не съехал с катушек.
P.P.S. А сайт у вас в целом хороший, контесты трогать боюсь, но решаю иногда архив. Мирзаянову уважение!
Congratulations! Codeforces... It seems the number of contests is decreased in this year (2020) then last year(2019)!!!
Congratulations CF <3
Congratulations codeforces my boy.
site is best
come on, there are lots of chinese participants. plz support alipay or wechat pay.
congratulations!
Congratulations Codeforces! The time I spend solving problems on this website is the best time I have across the day!
If Wechat Pay or Alipay could be adopted, more Chinese users will be willing to donate lol :)
cout<<"Congratulations! hope I am not last one !!! \n"; cout<<"Thanks Codeforces , for my today coding knowledge.";

Tillykke.
Codeforces is the place where my dream begin.Now my dream is over,but Codeforces can still make it continue.

CF工作十年; 这几天我感到非常高兴,因为Moein(艺术家)发布了他的新专辑,并且纪念了Codeforce的生日! 生日快乐CF!
Congratulations Codeforces and thank you Mike!
why there is no comments like "toss a coin to your Mike"?
Big Congratulation for making such a good platforms for us...Take love from my heart..Really appreciable.
No Alipay? Chinese people could contribute a lot!
The First palindrome!
Congratulations codeforces !!!!
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)_/¯
What does the hoodie look like?
Where can i preview the T-shirt?
Proud sponsor of a great website. :-)
Codeforces!Codeforces!Good!I hope I am the first one!
The Second Palindrome
$51915 is not Palindrome, but here it is:
:D :D <3 <3 Happy Birthday Codeforces
I guess that for three months we'll see only sponsored rounds, huh?
Congratulations!
Codeforces will live forever never worry MikeMirzayanov
Congratulations codeforces!
Are you going to use donations for creating dark theme? :)
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.

P.s. I seek my synonymous, Anca Pană! Love you all OTHERS and Happy 1st of March Day to all L/adies out there!a
Congratulations Codeforces~! By the way.. I've already donated $250, how do I get my hoodie? When is the hoodie supposed to be delivered?
Yandex + Visa/MC: За один раз можно заплатить не больше 15 000 рублей. Попробуйте уменьшить сумму.
PayPal + Visa/MC без регистрации и смс: Нет России
Майк рассказывает, что в таком случае делать
Thanks for this Amazing platform. It's changed my life!
Congratulations! I've got lots of fun in this platform, good job!
congratulation!
Why don't you support paying with wechat?
Congratulations Codeforces! But your attractiveness is becoming lower because of usual too strong pretests which makes hacking impossible or rare. Also then it is almost no difference between normal and edu rounds. I hope for more balanced rounds == solving > hacking, not solving >> hacking. Best wishes!
Congratulations!
Платформа просто великолепная. Есть все, что необходимо, но вот дизайн очень сильно устарел. Планируется какой-то редизайн?
How do the hoodies look like?
Has anyone actually seen a hoodie... :)) ?
Mircea (sAca)
I have some memory of gKseni putting them on display in previous campaign...
Codeforces, whare is my badge in profile?
what is the criteria for getting badge?
The 15$ donation.
Did anybody manage to donate with Revolut card?
Paypal doesn't accept my payment, even if I just pay by card or from the account. It says it can not accept the payment.
Does anybody here have a Revolut account? I can send money to you and you donate for me? can somebody help with that?
would you implement duels in the future?
Поздравляю с юбилеем! Решал задачи здесь ещё когда была бета-версия и номера раундов были двузначные и, пусть никаких успехов в спортивном программировании я не добился, этот сайт определённо сыграл свою роль в моём развитии как специалиста. К сожалению, тоже стал жертвой технических проблем с оплатой: при оплате картой через шлюз яндекс-денег выдаёт ошибку даже на 45$, через paypal в списке стран нет России. А напрямую через Paypal или ЯД отправить возможности нет...
MikeMirzayanov Lebanon is not an option as a country to select for MasterCard donations. How disappointing I was looking forward to support my favorite coding website.
Congratulations! I believe "More effort,more prosperity",I will continue the hard training,and I hope codeforces would be better and better!
congratulation
Any news on when the rewards will be available MikeMirzayanov? No rush, obviously, I'm just afraid I might be missing them, since I don't check the website that often.
