Imagine you're 40 years, you know the basics of computers, maybe some of the basics of the file system, but you've never created software - Still you want to learn how to create software and become a professional programmer and software developer. Well, that is an actual use case I've been assigned to by a friend. Hence, obviously time is of the essence, while at the same time I can probably assume the guy is fairly self driven and can research all the gory details on his own if given some pointers. My friend's friend has a college degree, so I can also assume he's self driven, motivated and able to indulge in long self studies once given a few pointers in the right direction. He is also a fairly smart guy, but literally knows nothing about software development.
If the above is a fitting description for you too, you've come to the right place. I realised instead of teaching him one on one, I could create a series of YouTube videos, associate these with some DZone articles, add some good references, and scale up my efforts - Such that others could also learn from it.
