Also Coursera has the whole system of problem sets and programming assignments etc.
That said - I'd be happy if someone could show me some decent Udemy courses?
The ai lectures on udemy are a bit weaker in my opinion. YouTube and university content is better.
In contrast, I have never paid for coursera, edx or audacity. A key thing is the price point of 15 bucks .. I don't feel bad at all blowing cash on the udemy courses .. it is like a movie ticket. A 100 usd course feels like real money.
As far as practical skills go, a Pluralsight subscription was by far the thing that helped me the most. As long as you stay with the well-reviewed courses, the information density tends to be extremely high. It's how I learned enough about desktop GUI dev via WPF to score a volunteer 'consulting'-type gig with a nonprofit, and that combined with what I learned from there about Angular got me my first job.
Having used both I think they’re just different. Udemy has very neat short courses while Coursera is really long and for some purposes, overly long and detailed.
Decent courses - I did a pretty great drawing course and Unity programming intro courses on Udemy that I really really enjoyed.
Udemy has a 30 day refund policy as well, so you can try a course out with low risk.
And as for Docker, this was my favorite: https://www.udemy.com/course/docker-and-kubernetes-the-compl...
