CodeFights Hello everybody, Just recently, I found this cool website [CodeFights](https://codefights.com/home). 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](http://en.wikipedia.org/wiki/JavaScript). 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](http://brainfights.com/). They have a similar site for mathematics [MathFights](https://mathfights.com/). I hope you like it. **UPD:** I asked them if they are going to add more languages and they replied this: — "As for adding mo...

An awesome list for competitive programming! This is a project I started from late January 2016. My motive is that: Although there's fantastic information out there, I think they're still spread all over the place. Therefore, in my opinion it would probably be cool if there's an [awesome list](https://github.com/sindresorhus/awesome) for competitive programming! ( *It's now featured on the main list!* ) I'm actively updating the list here: [https://github.com/lnishan/awesome-competitive-programming](https://github.com/lnishan/awesome-competitive-programming) # Awesome Competitive Programming [](https://github.com/sindresorhus/awesome) A curated list of awesome `Competitive Programming`, `Algorithm` and `Data Structure` resources. Created with a view to connecting people to information, this list below contains a complete collection of all the fantastic resources I've collected over the course of my 11...

CodeFights is officially launched, already out of beta [CodeFights](https://codefights.com) just went out of beta and the biggest change is that there are 3 new languages supported &mdash; C++, Python and Java (previously tasks were only in JS). My favorite feature is solving challenges where most people seem to compete for getting shortest source code to given task (tasks are mostly easy so main challenge is usually solving it with a shortest code among all solvers). One issue I see is that Python solutions have big advantage since they are very short, also it is pretty annoying to see people copy-pasting solutions from each other, hopefully it will be given some solution soon. By the way, users who perform good enough can post challenges themselves, would love to see new ones!

Invitation to IPSC 2015  The next edition of [Internet Problem Solving Contest](http://ipsc.ksp.sk) is here! In case you don't know (yet), IPSC problems come in a great variety, from standard algorithmic ones to problems where you interact with the grader or need to find a specific input. Most problems have an easy input worth 1 point and hard input worth 2 points; otherwise, the scoring is ACM-like, with WAs on easy inputs giving time penalty 10 minutes instead of 20. The input files are available for download and you only upload your outputs (in a similar manner to GCJ, except there's no additional time limit). It's a team competition for teams of three. IPSC 2015 takes place on 20th of June, from [11:00 UTC](https://www.timeanddate.com/worldclock/fixedtime.html?month=6&day=20&year=2015&hour=11&min=0&sec=0) and lasts 5 hours. You may register [here](http://ipsc.ksp.sk/2015/register). #### CONTEST IS OVER. | Registered teams | |:----------------:| (...
