Ask HN: What CS topics are schools not teaching?

Do you guys feel that schools just don't teach you what you really need in the real world to be a successful software engineer?

It took me 5-7 years to learn what I now know and I wished I learned some of these things way earlier (like version control, MVC framework, less, haml, node.js, mongodb, and many others). These were not difficult to learn but back when I first started, I just didn't know about these technologies/tools and lacked guidance!

If you were to go back in time, what things do you feel you have learned earlier in schools that would have saved you months/years of time in the real field?

I will combine everyone's feedback and develop a list so that future hackers can use it as a reference guide to help them save time.
