Learn Go in ~5mins

This is inspired by A half-hour to learn Rust and Zig in 30 minutes.

Basics

Your first Go program as a classical "Hello World" is pretty simple:

First we create a workspace for our project:

Deploying a subfolder to GitHub Pages

Sometimes you want to have a subdirectory on the master branch be the root directory of a repository’s gh-pages branch. This is useful for things like sites developed with Yeoman, or if you have a Jekyll site contained in the master branch alongside the rest of your code.

For the sake of this example, let’s pretend the subfolder containing your site is named dist.

Step 1

Remove the dist directory from the project’s .gitignore file (it’s ignored by default by Yeoman).

	//Moebius transformations in 3d, by reverse stereographic projection to the 3-sphere,
	//rotation in 4d space, and projection back.
	//by Daniel Piker 09/08/20
	//Feel free to use, adapt and reshare. I'd appreciate a mention if you post something using this.
	//You can also now find this transformation as a component in Grasshopper/Rhino
	//I first wrote about these transformations here:
	//https://spacesymmetrystructure.wordpress.com/2008/12/11/4-dimensional-rotations/

	//If you want to transform about a given circle. Points on the circle and its axis stay on those curves.
	//You can skip these 2 lines if you want to always use the origin centred unit circle.

	# Update 7 Oct 2010:
	# - This example does not appear to work with Chrome >=6.0. Apparently,
	# the WebSocket protocol implementation in the cramp gem does not work
	# well with Chrome's (newer) WebSocket implementation.

	# Requirements:
	# - rubygems: eventmachine, thin, cramp, sinatra, yajl-ruby
