[go-nuts] Re: Need some help on my basic "Backup size" calculator

See filepath.Walk (https://golang.org/pkg/path/filepath/#Walk) If you wish to recurse with ioutil.ReadDir or File.Readdir (https://golang.org/pkg/os/#File.Readdir), you have to do it manually. Nested structs -- it depends what you are doing. I would simplify it to: type Stat struct { FileCount

Feel free to report me to the CoC committee if you think that telling someone point blank they are wasting their time and creating noise without having a well defined problem or solution. And yes, I'm one of those "zealots" who can actually read and know that this programming language is called Go

[go-nuts] Need some help on my basic "Backup size" calculator

Hi there, I'm very new to Golang, and quite honestly haven't coded in a long time so bear with me if this is an very basic question. I'm trying to build a basic backup program, which will take a path (string) and then calculate the total "backup size" of the entire backup (and all the child fo

Why such a vicious attack? This type of behavior against those exploring generics in golang(i call Go this to spite the zealots) is a scourge gone uncheck for too long. No need for comments to be speckled with demeaning overtone. On Friday, June 2, 2017 at 4:17:54 AM UTC-4, Florin Pățan wrote:

Hi I think you wanted return ahost == bhost (instead of aport == bport) inside the addrCmp function, right ? Because the client is always assigned a random port for a TCP connection And of course, you will have to compare at nc (net.Conn) level, not at listener level, especially when listenin
