Hi!
Thanks for your feedback. I think it is not hard to make this program
data-race free if you give up readline library.
The problem lies on the fact that readline's Instance.Readline function is
not go routine friendly. It is a blocking call which won't return until a
line is entered or an inte
Wouldn't then the argument being passed into Less(Item) and Swap(Item) be
for two different interfaces?
One.Item for Less() and Two.Item for Swap().

You can embed the interface in two.Item:
type Item interface {
one.Item
Len() int
Swap(item Item)
}

Can anyone explain me why I should attempt to do this?
The below works for a single package only.
func TestMain(m *testing.M) {
setup()
exitVal := m.Run()
teardown()
os.Exit(exitVal)}
func setup() {
flag.StringVar(&util.ServerFlag, "server", "s", "server to set request for")
The sort.Interface is designed to operate on an indexed collection.
Certain data structures may not be indexed (ex. linked list) nor do some
algorithms need to expose that they are.
Lets say I have one package with the following interface.
package One
type Item interface {
Less(item Item)
Hi,
nice exercise!
I found out your version was having data races.
try your program like this
go run -race kseo.go -url ws://echo.websocket.org
This program does not need any goroutine, imho,
package main
import (
"flag"
"fmt"
"bufio"
"os"
"net/http"

Although unusual, I did have a case where it was handy to use double the value
of CPUs. It was a situation where there were a number of low-priority,
compute-bound processes and a bunch o
If you don't care about preserving the order of the elements in the slice,
you can do something like this:

The functions I used are documented here: https://golang.org/pkg/reflect/

The 32 bytes were just a product of the hash function that we were using,
but I've simplified it by changing the hash function to one that only
generates 8 bytes.
My current solution is:
func EmailToID(email, salt string) int64 {
d := sha3.NewShake256()
d.Write([]byte(email))
d.Write([]byte(sa

This could be a bit better explained on the golang website.
First, note that there are potentially three environment variables
involved: PATH; GOROOT and GOPATH.
The Getting Started guide (https://golang.org/doc/install#install) gives
quite a lot of help, and you should read that thoroughly.
Usually, GOMAXPROCS==NumberAvaliableCpuCores (the default value since
go1.5) will get the best performance.
For some special cases, a smaller GOMAXPROCS value will perform better.
But A GOMAXPROCS value larger than NumberAvaliableCpuCores will always

The default of using only one thread to run goroutines default changed with Go

less relevance in practice, rendering the article as outdated in that regard.

Can someone let me if it is possible to refer a different package from godoc of
a package? For example let's say I have a package src/logger/. In
src/logger/doc.go I need to refer src/config/. Something like @see in
javadoc.
Is there a recommended way?
I am on Go 1.7.

Anybody can write a spec and deem it a standard.
