I don't think that was the point of his exercise.

It's probably nigh impossible to "memorize" every single one. I would advise against skipping the "boring" tutorials because even if you don't need to memorize anything, having exposure to, and getting an innate sense of at least what's possible is very much advantageous. You may not think you'll need them now, but I guarantee at some point you'll be trying to achieve something and think, "dang, I wish I could just do X with Y" and then you'll think, "wait, I remember something in a tutorial I saw that did something like that." That will then put you on the path to tracking down whatever it is, usually in the docs.

Also, always keep a tab open to the Python (or whatever language) docs. Can't stress that enough.

Ah right. Those that can - do. Those that can't - administrate.

What, did you just start developing? These kinds of things aren't specific to Oracle nor are they rare - this shit happens all the time. That's what makes good developers good - knowing how to efficiently troubleshoot. If Oracle recommended a build and you didn't use that to begin with, that's totally on you.

Wtf is this even supposed to mean?
