Tired of going through 30+ pages of standings on atcoder in attemps to find someone by their handle?

There is no "search by handle" function at atcoder?

You miss "friends" feature at atcoder?

Here is a LIFEHACK, how you can find someone in standings easily!

Steps:

  1. Open random page with standings
  2. Press Ctrl+U in chrome (or some other hotkey to view source code of the page)
  3. Now you have a full rating! Just press Ctrl+F (again, in chrome) and look for your friend!
  4. Profit! Now just go and upvote this post

Hello, Codeforces!

I would like to invite you to participate in a new csacademy contest. Round #9 will take place on Tuesday, July/26/2016 16:00 (UTC). I will be one of the problem setters of these round, together with mgch and the CSA team. This round will also feature some money prizes, as follows:

  • First place: 125$
  • Second place: 100$
  • Third place: 75$
  • Fourth and fifth place: 50$
  • Two more special prizes, each consisting of 50$. The criteria for the special prizes is not chosen yet, but we will make it public after the contest.

This round will also feature problem statements in Russian. Many thanks to Yury_Bandarchuk for doing all the translation work!

Contest format:

  • You will have to solve 7 tasks in 2 hours and 30 minutes.
  • There will be full feedback throughout the entire contest.
  • Tasks will not have partial scoring, so you need to pass all test cases for a solution to count (ACM-ICPC-style).
  • Tasks will have dynamic scores. According to the number of users that solve a problem the score will vary between 100 and 1000.
  • Besides the score, each user will also get a penalty that is going to be used as a tie breaker.

About the penalty system:

  • Computed using the following formula: the minute of the last accepted solution + the penalty for each solved task. The penalty for a solved task is equal to log2 (no_of_submissions) * 5.
  • Solutions that don't compile or don't pass the example test cases are ignored.
  • Once you solve a task you can still resubmit. All the following solutions will be ignored for both the score and the penalty.

The CSA team still recommends using an updated version of Google Chrome. If you find any bugs please email them at contact@csacademy.com

Hi!

Today I'm proud to announce that I'm starting regular streams on twitch. On these streams I'm going to solve timus tasks (maybe other archives later) as a part of my trainings. Of course, I'll try to comment what I'm doing.

To give it even more action, I'm introducing to you challenges. Pick your favorite(or maybe not) problem on timus with at least 1000 authors and write its ID to the chat. If you are lucky, I'll pick your problem. If I get AC in 30 minutes -- I win(nothing happens), otherwise you win and I'll do 10 push ups =) (at least, I'll get in shape)

The first stream starts today at 20:00 MSK and lasts till sleepy time.

I'll try to comment in english. Unfortunately, my english is bad, it's not my native language. If I face a lot of troubles with this, I'll switch to russian.

The link to the stream.

Stay tuned!

UPD. Thanks guys, that was really amazing. The second stream is gonna be today at the same time (20:00 MSK)

During 5,5 hours I've solved 20 problems and haven't solved another 2 (failed on 1004 and 1873). So the current score is 20:2. So I've already done 20 push ups =) Come on guys, there are a lot of not-easy problems among problems with at least 1000 authors! I'll think about reducing the limit of 1000 authors, but let's try one more time.

I've uploaded screencast from the first stream on youtube. But the screencast misses the very important part of the stream -- the chat. So it's much better to watch the stream live than as an offline record.

Also, don't forget to follow my channel on twitch to be able to get notifications when the stream starts. Good luck!

UPD 2. Looks like, this challenge system was boring enough, so as my stream (I have lost only 4 times). So, I am introducing to you the new system. Now, you can choose problem on timus with at least {balance} authors. What's the balance? By the start of the stream it's 800. If I win challenge it decreases by 50 authors. If I lose it increases by 50 authors. So, now it's almost impossible to see the score 10-1 at my stream.

Today's stream will be at 22:30 MSK. Come!

UPD 3. 25-06-2015 For those, who are not sleeping at night, or just at the other end of the world, stream starts in 20 minutes!!
At 03:50 MSK

UPD 4. 01-07-2015 Today is the stream day. Stream starts at 23:00 MSK

UPD 5. 02-07-2015 Exclusive stream with subscriber!!! Start at 21:45 MSK

UPD 6. 21-07-2015 Streams are back. Start at 00:00 MSK

UPD 7. 19-08-2015 Stream starts at 00:00 MSK . Feel free to prepare some problems with >= 400 authors =)

UPD 8. 01-10-2015 STREAM!! Starts at 00:00 MSK.

UPD 9. 08-10-2015 Streaming mathfights with commentary. Starts at 20:00 MSK.

Всем привет! Я всю жизнь использовал windows и far manager для написания кода. Он очень шустрый, позволяет сразу делать много вещей, быстро смотреть/изменять input/output файлы, чекать консоль и многое-многое другое. Но, недавно созрела мысль "хочу полностью перейти на линукс", и то, что меня в этом больше всего останавливает -- я не знаю как в нем писать контесты так же удобно, как в винде. Полных аналогов фара под линуксом нету. (если есть, то можете мне о них рассказать, если это не Midnight Commander)

Поэтому, ищу текстовый редактор, который будет подходить под максимальное число требований:

  • максимально-шустрый (я к этому очень чувствителен, если будет задержка в лишние 0,1 сек между переключениями вкладок, я ее замечу)
  • возможность рассплитить экран на несколько частей (хочу слева писать код, справа-сверху входной файл, справа-снизу выходной)
  • курсор может свободно находиться за пределами конца строки (в far-е это называется cursor beyond end of line)
  • с интуитивно-понятным и удобным-стандартным интерфейсом (vim не предлагать)
  • конечно же, должна быть подсветка синтаксиса
  • желательно, хотя бы базовое автодополнение, но это не обязательно

Пожелания:

  • если легко будут настраиваться макросы (нажал F7, у тебя все скомпилировалось), это будет плюсом
  • легко настраиваемый -- например, можно легко поменять colorscheme или шрифт, если не нравится
  • можно сделать курсор "горизонтальным"
  • подсветка столбца, в котором находится курсор (в фаре эта опция называется cross, чтобы ее включить нужно прожмякать f9-o-u-c и поставить галочку)
  • можно включить автоматический перевод всех tab-ов в пробелы, но это не обязательно

Что используют линуксойды, чтобы писать контесты? В первую очередь, хочется услышать мнения тех, кто использовал far для контестов и знают, насколько он удобен.

P. S. Требования "нужно то, что можно юзать на финале" нету.

Доброго времени суток!

После черного дня кодефорсес (а может и за некоторое время до) у меня перестала работать авторизация через vk, приходится каждый раз входить через gmail. Кто-нибудь еще сталкивался с этой проблемой?
