I don’t even understand why people like GitHub so much, its source management sucks.
It's not that complicated... people use it because everyone has an account there and so your project gets more visibility (and your profile too, for those who plan to flex it when they look for the next job) and more contributions. Even a lot of projects that aren't on github have some sort of mirror there for visibility.
Suppose you wanna contribute to gnu grep (or whatever)... do you happen to know off the top of your head where the source repo and bug tracker are? And do you know what's the procedure to submit your patch?
If you are a company doing closed source, I agree that I don't see why you would choose github over the myriad alternatives (including the self hosted ones).
Look for ways to do things separately and you will find much better tools
That's a great way to spend your resources developing yet-another-source-forge-thingie instead of whatever your actual project/product is supposed to be :)
I've heard this over and over... what's the difference security-wise between sudo running some install script and sudo installing a .deb (or whatever package format) ?
