How to code remotely?

Question

Programming

For example, I have a friend who lives in another city, how can we work on the same project? (just curious to know how this happens in the future will come in handy) :)

Answer 1

Git + https://bitbucket.org or github.com if you're not ashamed to shine :)

Answer 2

Read more about version control systems.
Github is just a nice implementation of a public git server with a web interface and some extra goodies. But if it bothers you, get git on your two machines, figure out how it works - any developer should be able to work with at least one version control system.
