I don't like when

you have a couple of years of experience with some language and you're like "I should read a good book about it, and have some proper solid foundation instead of playing by ear".

So you get a book and what follows is a very jarring experience.

Because for the first 8 chapters they get into the basics of the language.

You're occasionally like "interesting, I did not know that".

But for the most part you're like "yes, for fucking christ I know that, everybody knows that",

or you complain about the author being redundant,

or about the outdatedness of the book, since most documentation is now in the interwebs

or you reach flawed conclusions out of frustration like "this isn't making me any money, I could get on upwork, or do some bounties instead of wasting time on this"

then you start to skim through the pages like "I know this, and this, and this" until you realize you're in some page you have no fucking idea what it's talking about, as if you ended up on the wrong side of town

so you start backtracking (frustration is going critical at this point)

but backtracking is annoying because it's not well defined where you stopped getting it, as if in page 33 you were getting it 100%, but 0% on page 34, it's more like a gradual, irregular decrease,

so you have no idea where to start re reading from.

you just shove that shit into the wall at that point.

Some of these are learning discipline problems.

I guess there are ways to mitigate them, such as writing down questions of things not understood, co reading, etc.

But the one thing I don't think I can't get past is when authors write like shit,

like being redundant, using different words to say the same shit

or using confusing sentences that can mean different things at the same time,

or using the incorrect terminology, eg: if I were teaching OOP, saying shit like "classes create objects" but later on saying something like "classes create instances".
They usually nail the definitions the first time, but then use different terms for the same thing. It's shit.

And I think that's a writing culture that I hate.
From school you are taught to bot repeat words.

To say the same shit in different ways.

To be descritive, but vague.

That's absolutely shitty for programming in my opinion.
