Honestly the best thing is and has always been learn by doing with current "professionals" (people working in the field). Try something, get feedback, adjust and learn and grow. Nothing else compares to real world integration.
Yup. But they don't work. Same problems. They'll get dog piled by litigation, threats, and investigations. meanwhile said whistle blower is unemployed and getting raked through the mud. Not much protection going on.
The laws are there, sure. But if you become a corporate "whistle blower" you're not likely to get a job again. And the company will just drown the accusations in fines and litigation and nothing changes because we're poor and solo, because we're not unionized because if we try we get fired (again, illegally).
Sounds like I just gotta get better with rebasing. But generally I do my merges clean from local changes. I'll commit and push, then merge in, push. Then keep working. Not too hard to track but I've found it's the diff at MR time that people really pay attention to. So individual commits haven't been too crucial.
I personally never rebase. It always seems to have some problem. I'm surely there's a place and time for rebasing but I've never seen it in action I guess.
Tabs. But really with modern IDE it's irrelevant. Whatever the tech lead says I guess.
