I bought a Packt Publishing book against my better intuition because it has just so much about some many things, but one look at the following in the Generics Chapter 13 and I immediately regret my decision:
type Numeric interface {
type int, int8 // etc.
}
Anyone paying any minimal attention to generics in Go immediately can spot this as a proposed spec that is more than a year old and didn’t make it into the final 1.18 (which I’ve been enjoying all month). Here’s what did make it in:
type Numeric interface {
int | int8 // etc.
}
It’s no surprise that glancing at a few other pages reveals how out of date the book actually is. It’s like this guy took all his coding notes from RedHat and bundled them together quickly after Packt contacted him to publish a book, which is how all books from Packt get published, massage an engineer’s ego, rush them a book out, massage another engineer’s ego to get them to “review” it, and push it out with no professional technical vetting of any kind from anyone else. This is why Packt Publishing books are beyond shit usually.
I’m super sad from this – especially since I paid money for it. I mean, there are some good things to read that are covered pretty well, but the Internet covers them just as well and is faster to query. Hard pass on this book if you are thinking of getting it.
And besides, who the fuck puts capital letters in their file names for Go development. I mean how clueless is this guy. Oh yeah, he works at RedHat.
