>Real world examples tend to have a huge amount of unpleasant details which hinder transfer of the underlying concepts. This. I hate all these blogs, where they are teaching, for example, Django , and start by asking us to setup Postgres/Mysql "because it is a real world database". And I just quit, as I dont want to deal with the hassle of setting up Postgres, or spend hours setting up Docker on my personal Mac. And many blogs for beginners will spend 20 minutes teaching them to setup Git "because it is good for you". And I know many beginners just get overwhelmed and quit Standard Reddit/HN condescending response "But everyone should know git/mysql etc! Are you not a REAL engineer?" to which I say: Fine, teach them separately.
