I do some android work on my desktop and I am starting to do some PHP work on a website. I just started doing some collaboration with some freelancers on both platforms. I would also like to do more coding on my laptop (android and eclipse export and importing is annoying). I have a GoDaddy shared hosting and a neglected Ubuntu 11.04 server at home.
I need to setup something to make this all easier, should I do some sort of SVN? I don't make much money on my projects, so I don't want to pay for an online repository. Any suggestions?
