Problem

1. I am much more productive and performant when I program with another person while working through a problem.
2. Other people are not usually around or available to program together on an issue.
3. Programming along

Simple Solution

1. Buy a rubber duck

Simple List of Websites

• Project Euler - The #1 goto site for coding practice on the internet, IMO.
• Rosetta Code - Unlike most other sites on this list, Rosetta Code is not a contest site. There are problems listed, and so are the solutions, in a plethora of different languages. You can go check out the problems, solve them, check out other solutions. It's goal is to solve problems in as many languages as possible.
• Code Chef - Holds monthly programming contests
• UVa Online Judge - Contains hundreds of problems, which can be downloaded too
• Coderbyte
  • Another coding competition site
• The Python Challenge - A pretty cool & very difficult challenge. Makes you think, a lot, and not just for coding.
• Code Golf Stack Exchange - A programming challenge with a twist - The code has to be the smallest.
• Anarchy Golf - Another place to golf

###Querying the database

Now you just need to learn a little bit of new sqls for selecting stuff (creating and updating is transparent). Find records that contains a key named 'foo’:

Person.where("data ? 'foo'")

###Checkout a remote branch and set it to track the remote

This will keep your local branch in sync with the remote on push/pull/fetch

• Official tracking branches docs
