Converting libraries to Ember CLI addons

In this guide we will cover two main cases:

• Ember specific library
• vendor library

Ember library

The Ember library will assume that Ember has already ben loaded (higher in the loading order) and thus will assume it has access to the Ember API.

class Metric {
	static function main() {
		var coinRadius:Millimeters = 12;
		var myHeight:Centimeters = 180;
		var raceLength:Meters = 200;
		var commuteDistance:Kilometers = 23;
		
		diff( coinRadius, myHeight ); // 1.788 meters
		diff( raceLength, commuteDistance ); // 22800 meters
		sum( commuteDistance, coinRadius ); // 23000.012 meters

ZFS Snapshots and PostgreSQL

I recently set up a host running Ubuntu 14.04 LTS, ubuntu-zfs, and PostgreSQL 9.3. Using the ZFS snapshot feature I was able to make a snapshot of the file system holding the PostgreSQL database, write the snapshot to a compressed file, transfer it to another Ubuntu 14.04 LTS host running ubuntu-zfs, restore it, and launch PostgreSQL using that data directory with all the data (seemingly) intact.

The database is very low-traffic, so I do not know how effective this strategy would be for a busier database.

I take no responsibility if you attempt this setup and it causes data loss or other issues. Use it at your own risk; this document is meant to explain a potential setup and open discussion about limitations and potential improvements.

I have spent quite a bit of time figuring out automounts of NFS shares in OS X...

Somewhere along the line, Apple decided allowing mounts directly into /Volumes should not be possible:

/etc/auto_master (see last line):

#
# Automounter master map
#

+auto_master # Use directory service
