#How to install Arch Linux with MBR without swap

This tutorial assumes you're installing arch to /dev/sda. You can replace /dev/sda with the device name you want to install arch to.

##Partitioning

Make a single partition on an MBR partition scheme to install arch to.

We'll call this "/dev/sda1". Edit this if it's some other device file.

$ ssh -A vm
$ git config --global url."[email protected]:".insteadOf "https://github.com/"
$ cat ~/.gitconfig
[url "[email protected]:"]
	insteadOf = https://github.com/
$ go get github.com/private/repo && echo Success!
Success!

New ES6 Constructor Semantics and Usage Examples

Manual super: Alternative Design where subclass constructors do not automatically call superclass constructors

This Gist presents a new design of class-based object construction in ES6 that does not require use of the two-phase @@create protocol.

One of the characteristics of this proposal is that subclass constructors must explicitly super invoke their superclass's constructor if they wish to use the base class' object allocation and initialization logic.

An alternative version of this design automatically invokes the base constructor in most situations.
