Sorry about that, I'm my newsletter provider (Substack) which is very buggy sometimes.

I wasn't aware of bonuses-as-a-service. Thanks for sharing.

Generics are already there.

His review contains comments annotated on a book of 300+ pages. I don't think it would have made this section any better by deep diving into his review.

Outdated I'd rather say :) I documented here https://100go.co/#not-being-careful-with-goroutines-and-loop... but you're right, it was fixed (alongside 2 other mistakes in the 100).

No worries I didn't take it as a criticism. I understand your point. I mean when we sign a contract there's a minimum number of pages to write. But personally, I never felt the pressure of having to add more stuff.

Instead, my DE multiple times told me that it's better to favor just-in-time teaching over just-in-case teaching. Meaning multiple times, he made me drop certain section because they weren't really serving the chapter. They were "perhaps helpful" and he made me drop all of those.

I guess it also depends on who you're working with and which publisher. On this aspect, Manning was fair, imo.

I said I was a source of inspiration for the mistakes in my book. Said differently, I've done a lot of mistakes myself which ended up being a section in the book.

It's your opinion, nothing wrong with it. Let me try to see if I can make you change it at least a bit.

> The first paragraph is totally pointless - we are reading a book about 100 most common mistakes, obviously this mistake is very common, how did this increased the value?

There are different levels in terms of common mistakes, and this one was probably one that all the devs did at some point. So I think highlighting the fact it's a frequent one does make sense.

> Then we have another line that explaining what happens in the code, which is totally useless because the code is super trivial.

I have a rule: always explain the intention of the code. Even if it's 5 lines of code, it helps the reader to better understand what we will want to highlight.

> Then the code, with more explanations on the side as if the previous line was not clear.

The explanations on the side do not impact the size of the book so the argument doesn't hold. I did it in many code snippets to highlight where the reader needs to focus.

> I understand that book publishers feel they need to justify the price of a book by reaching the 300p mark in some or other way

This is more about guiding the readers, making sure the expectations are crystal clear and that they can follow me throughout an explanation. You judge it as a criteria to justify the price of the book, but it's not the real reason. At least not for my book and I'm sure it's the case for many others :)

#63 isn't about the lack of execution guarantees when you execute multiple goroutines without proper synchronization; it was related to loop variables and goroutines.

That's why Manning will consider a 100 Rust Mistakes edition.

More details here: https://100go.co/#not-being-careful-with-goroutines-and-loop.... My example was probably terrible as it's one of the three mistakes in the book that aren't relevant anymore, thanks to Go's recent updates.

Thank you very much for your comment, though. It means a lot.
