I can't log in. Some pages give out 404 errors and it's really slow.

Do you have the same problem ?

Hello everybody,

Just recently, I found this cool website CodeFights. I find it fun and I want to share it with you.

The idea of the site is to improve your debugging skills. The site provides you short codes, which have a bug in one of their lines and you have limited time (1-3 min) to find and correct it. It is still Beta and the codes are written in JS. The codes are short, simple and most programmers will find them easy to read and debug. I hope they add more languages soon. There are many achievements/badges. The detailed rules are simple and you will understand them in a game (or two).

The site was created by BrainFights. They have a similar site for mathematics MathFights.

I hope you like it.

UPD:

I asked them if they are going to add more languages and they replied this:

— "As for adding more languages, happy to let you know that we are very close to releasing 3 new languages including C++ ;)." — CodeFights.

Woohoo!!

Hello everyone!

I have noticed some strange rating changes (at least strange for me) in the recent Codeforces Round 261 (Div. 2).

These are the top 5 (Div 2) users + their old and new rating:

1. vanhanh.pham — 1396 — 1761
2. ElemeNtLz — 1556 — 1772
3. MLboy — 1500 (unrated) — 1805
4. mssjtxwd — 1686 — 1795
5. yyfkiller3 — 1500 (unrated) — 1805

ElemeNtLz had better old rating than yyfkiller3 — 1556 > 1500 (unrated)

ElemeNtLz placed better than yyfkiller3 — 2nd is better than 5th

But yyfkiller3 ended up with higher rating than ElemeNtLz. I think that is strange because ElemeNtLz did better overall and had higher rating, but ended up with less than yyfkiller3. — 1772 < 1805

Same goes for these pairs (and probably more):

ElemeNtLz — MLboy

mssjtxwd — yyfkiller3

But this is just my opinion and if you have your own (that differs mine), please share it.

PS I do not know these users and I am not trying to defend or offend them.
