Also for #2 currently the company I work for is 'everything you write is ours'. Now in practice they do not really care but I really do not want to go through the months of BS paperwork (and yes it is that bad) just so I can put some project I have on github. So at this moment my github is mostly just 'git' fiddling things. Where I use it to fiddle with remote git, or some weird thing I got git into and how to fix it. No real code there at all. So everything I have is private.
