I remember someone in my team using WMI too. Not sure if it is as good as the other options listed in the article

Any idea if the database videos can be downloaded, just like the computer science lectures

yes , they can be. There is a tab on the upper right corner if you are signed on for the course.

Does anyone know if these videos will be available after the courses are over? I'm in the ai class and I'd like to do the others too but I don't have the time to do all of them.

All of the videos for the AI class are available on YouTube.

thanks mate! I will try it out

Anybody explain 'edition mode' 'insertion mode' ? New terms?

I'm not sure where those terms come from. "insertion mode" is described by the Vim documentation as "insert mode", because what you type on the keyboard is inserted into the document. "edition mode" might be a typo or English-as-a-second-language mistake for "editing mode" because that's what you do in that mode; Vim's documentation just calls it "normal mode".

"Edition mode" is what the author calls "command-line mode".
