Linux from scratch - eviltoast

Hi everybody, I’ve been using linux for over 15 years with a huge gap in between. I think i stopped at 14 (Ubuntu) something and started again at 20 something. So i had to learn alot again. Luckily it all came back quick. Now since this week I started linux from scratch to learn more about the way it’s build. I’m also going to get some education to point myself in the direction of a linux job. I just love the way it works. It makes sense to if you now what I mean (which you probably do)

I have two questions. Are there things I should try with LFS after completing my build? And what are some good linux educational sites? I’m currently thinking of the linux foundation. Anyway thanks for reading. Greeting from Belgium! Mr. Nowhereman
