@nixCraft as a LinkedIn Learning instructor, the biggest reaaon is it takes longer to write and publish a good tutorial than it does for the material to get updated. Second is we as instructors f’ed up checking all our environment settings to match our learners or transposing the code form out machines to print/video/blog. Third is the learner made a tiny syntax error they don’t see because they are not experts at the material yet. Fourth, all of the above, just two tutorials back in sequence , though it matters now.
@nixCraft Reminds me of the time, when I tried to learn Ruby + RoR. I would get up to some point in the tutorial, then error, then searching around for clues how to solve the error, getting a bit further, but ultimately my state and the state in the tutorials diverged and I could scrap it all again.
I guess 2 reasons: Unstable APIs and lack of understanding of what happens behind the scenes, so that one cannot fix it oneself.
