Recently, I've talked to some engineer friends, and some core IT topics came up. Topics like virtualization, specific protocols like HSTS or how browsers work.

During this conversation, I realized that I don't know enough about these topics, and now I want to learn.

The thing is, getting an overview of these areas is enough for me. 10 hours of knowledge on a specific topic is too much, and I won't remember the details anyway.

Finding such resources proves difficult, because I cannot even properly put them together in a category.

So, there are 2 questions. Do you know what I mean? And if so, how would you categorize it? And do you know about any resources for that?

Podcasts would be ideal, so I can listen to it on my commute, but anything is welcome.
