I owe my Java career to following a Spring for Beginners course. It did more to accelerate me forwards than, at that point, 2 years of university.

From my experience most corporate classes are pretty bad. It seems to sell these the main skill is to sell to execs and make them feel good, not to have good classes. Pretty much like enterprise software is sold not to actual users but to execs who will never use it.

How many managers would give you time off to study a udemy course though, vs a £1000 professionally run one?

It’s frustrating that the main advantage of paying a lot for a course, is having some proper time to do it.

My team which manages our company's ecommerce website inherited maintaining an iOS app that was being developed by a contracting firm. No one on my team had much experience in iOS. My company is extremely frugal. I bought an intro to iOS course on Udemy for the five of us for about fifty dollars total. It was excellent. Was definitely blown away by the quality and the price. It got us quickly up to speed on xcode, debugging, swift, view creation and publishing to the app store among other things. I am sure there is junk content on udemy, but there is also really good content that is worth more than the price.

We as a team also did a four hour course on TLS and PKI and it was a game changer. It was much better than reading up stuff.

Oh nice! Whats the name? I dont need it. But i try to teach this stuff to newcomer!
