Why use empty struct{} and not int or string for context.Value() key types in #go

Use struct{} as keys for context.Value() in Go

In the other file of this gist I detail why we should use struct{} as context.Value() keys and not int or string. Open gist to see main.go but the TLDR is:

	type key struct{}
	ctx = context.WithValue(ctx, key{}, "my value") // Set value
	myValue, ok := ctx.Value(key{}).(string) // Get value

Public Domain Software #blog

TLDR

Public Domain is not a license and isn't legally accepted in some countries. So if you want to give stuff for free, it's better to just license it under MIT or BSD.

Public Domain Software

The term “public domain” refers to creative materials that are not protected by intellectual property laws such as copyright, trademark, or patent laws. The public owns these works, not an individual author or artist. Anyone can use a public domain work without obtaining permission, but no one can ever own it. - Stanford University definition

Simple GUI example using https://github.com/zserge/lorca. Shows Go<->Js communication. #go

GUI programs using Go and HTML/CSS/JS

Superior to similar solutions. Doesn't use electron or cgo. Easy communication between Go and Js. Can easily use libs like React, Vue and Angular.

This is a demo app using GUI library https://github.com/zserge/lorca which requires only Chrome and might even work with Firefox in the future.
