Re: All your open source code
M$FT buying Github.com is THE WORST CASE scenario.
Look at LinkedIn, Skype, Minecraft, Nokia, WebTV - M$$$ is the worst company, it makes products worse and they are dying a slow death as soon as they get bought.
If Github indeed sells to M$ it is a big blow for the free open source software community.
Open source software alternatives to GitHub:
the most lightweight and best performing is GOGS (golang application):
And GitLab (though very slow, Ruby code, unstable SaaS, SaaS runs on Azure cloud, aka M$$$)
