What are the good online tech courses that you are willing to pay?

I use Udemy a few times a year. The instructors are terribly under-paid, and the content is typically very high quality but low depth. It's great for picking up a new skill to a useful degree and getting you ready to continue learning more in-depth material elsewhere.

Eg, great for learning a technology or programming language, but often not great for advanced features of that language.

Whenever you can, use one of the instructors coupon codes prior to buying a course, otherwise the instructors only get about 27% of the money [1] (or less if it's on mobile due to app stores), which is why I decided to not make a game-programming course a couple of years ago.

I've never done a bad Coursera one. Probably luck but still. Currently working through Colorado Boulders' FPGA for Embedded Systems course. I'd also recommend anything by Harvard/MIT on edX. The MIT Advanced Manufacturing micromasters, as well as the finance one, were fantastic.

At this point I am basically an unpaid shill for this company but:

Udacity

While courses from Coursera and EdX are also excellent, Udacity consistently makes me work hard and actually expend the energy to understand non-trivial tech.

Ardan Labs: Ultimate Go

I worked for 3 years as a Go developer before doing this course and I still learned so much from it. Thank you Bill Kennedy, you're a wonderful instructor!

Any of David Bezley courses [1]

I'm taking one of Meta's certification courses on Coursera right now.

None, excluding certifications (AWS, Google, etc.)

None. I think that online tech courses are outdated quickly so I prefer to learn by coding every day
