My trick to remember:
You can link to a target without giving a name to the link. ln will use the basename of the target file then. You can’t create a link without a target, so target has to go first since it’s not optional. Did it for me
There is a way with chmod in bash to change files and folders with files getting no execute bit and folder do (rwX instead of rwx). It’s in the man pages but good luck finding it via Google. Stackoverflow just suggests using find over and over again.
That did it for me.
I have a theory: information is best remembered if it is acquired solving a problem.
Play with the new tech, hit a roadblock, read and learn. That way you are motivated, know why you are reading the stuff and also only learn the stuff that isn’t intuitive.
Depending on experience many things are just like something you already know and easy to learn/remember, others are not. Don’t waste your time learning the first.
On the other hand, put me into a room with a teacher, who tries to teache me specifics about a tech I don’t care about and I will promise you, I will learn nothing. Even worse, I will start to hate that tech.
