Golang interfaces explained. This is a very helpful article. I found the interfaces section on tour of go to be nonsensical jibberish. Here is the pure jibberish

var a Abser
f := MyFloat(-math.Sqrt2)
v := Vertex{3, 4}

a = f // a MyFloat implements Abser
a = &v // a *Vertex implements Abser

How is this implementing anything? It looks to me like assignment? Makes ZERO sense. Most of the tour is awesome and makes sense but this entire section is pure fail. It causes more questions than answers. Like this
// In the following line, v is a Vertex (not *Vertex)
// and does NOT implement Abser.
a = v

Ok  I am new. This to me looks like reassignment. Once again how does assignment make something implement something? And why not explain it to the new users? Any details as to what is going on would be helpful to new comers. If you quote it out and run the program it works. This section needs heavy updating and explaining. This is purely WTFF??? This is literally the absolute worst part of the entire Tour. This is where I hit my WTF moments and had to start using google to DECIPHER the encoded message.

Thinking in Go. This article is a must read for anyone coming from an OOP background such as Java wanting to understand Golang. There are no classes. No inheritance. No generics. No this. No that and No. Golang requires thinking entirely differently. Interfaces are the hardest thing to wrap my mind around so far.  The implicit magic is something  I don’t like I prefer words like implements to make my code more clear. If I could just find good enough information I’d understand it. I literally have to undo all of the years of OOP damage. When I first encountered Golang I heard that interfaces confused most new people, I understand why now. It is not just interfaces it is learning to think and build software in an entirely new alien way.

More on Golang Interfaces — because they are nothing like interfaces you have face in other languages. The whole implementing thing is just totally wild. I hate implicit bullshit. It’s just unneeded magic for no reason other than to drop a few characters.https://www.digitalocean.com/community/tutorials/how-to-deploy-a-go-web-application-using-nginx-on-ubuntu-18-04

Thinking about Interfaces in Go — another great article about Golang interfaces. Interfaces are the most complex thing in go, so multiple references helps  more.

Go for Java Programmers — this is an awesome series of articles for java programmers coming to Golang. This is also helpful to PHP programmers since PHP is so similar to Java these days.
