Creating a blank array

The following incantation creates an array of length 10.

Array.apply(null, {length: 10})

Can't access ssh over `The Town Hall` network

This affects [email protected] clones, which caused me an issue with bower. The fix in this case is to cause git to use https:// rather than git:// by running this command in the working directory:

git config url."https://".insteadOf git://

To revert the setting run:

	#!/usr/bin/env bash

	# Deal with case that we're on the initial commit
	[[ $(git rev-parse HEAD) == $(git rev-list --max-parents=0 HEAD) ]] \|\| PARENT="HEAD^.."

	cat <(git log ${PARENT}HEAD --format=format:'# %s - %h - %ai%n%n%b%n') CHANGELOG.md > CHANGELOG.tmp
	mv CHANGELOG.tmp CHANGELOG.md

	#!/usr/bin/env python3
