#API for single page app use

###addthis.layers.refresh()

Updates the share URL of all floating tools (sharing sidebar, for instance) to the current URL
Creates inline tools on any elements that do not yet have a tool rendered for it

I can see someone with a single page app doing one of two scenarios:

//always refresh on URL change

Searching for Files

Find images in a directory that don't have a DateTimeOriginal

exiftool -filename -filemodifydate -createdate -r -if '(not $datetimeoriginal) and $filetype eq "JPEG"' .

###Output photos that don't have datetimeoriginal to a CSV### Note this can take a long time if you have a lot of jpgs

Let's Encrypt on Ubuntu 14.04, nginx with webroot auth

This document details how I setup LE on my server. Firstly, install the client as described on http://letsencrypt.readthedocs.org/en/latest/using.html and make sure you can execute it. I put it in /root/letsencrypt.

As it is not possible to change the ports used for the standalone authenticator and I already have a nginx running on port 80/443, I opted to use the webroot method for each of my domains (note that LE does not issue wildcard certificates by design, so you probably want to get a cert for www.example.com and example.com).

Configuration

For this, I placed config files into etc/letsencrypt/configs, named after <domain>.conf. The files are simple:

	<?php
	/**
	* Do simple reliable floating point calculations without the risk of wrong results.
	*
	* @see http://floating-point-gui.de/
	* @see the big red warning on http://php.net/language.types.float.php
	*
	* In the rare case that the bcmath extension would not be loaded, it will return the
	* normal calculation results.
	*

	#!/bin/bash
	#

	BACKUPDEST="$1"
	DOMAIN="$2"
	MAXBACKUPS="$3"

	if [ -z "$BACKUPDEST" -o -z "$DOMAIN" ]; then
	echo "Usage: ./vm-backup <backup-folder> <domain> [max-backups]"
	exit 1

	/**
	* Simple userland CPU profiler using v8-profiler
	* Usage: require('[path_to]/CpuProfiler').init('datadir')
	*
	* @module CpuProfiler
	* @type {exports}
	*/

	var fs = require('fs');
	var profiler = require('v8-profiler');

	# Install x-related to compile x11vnc from source code.
	sudo apt-get update
	sudo apt-get install -y libxtst-dev libssl-dev libjpeg-dev

	# Grep source code.
	wget http://x11vnc.sourceforge.net/dev/x11vnc-0.9.14-dev.tar.gz
	gzip -dc x11vnc-0.9.14-dev.tar.gz \| tar -xvf -
	cd x11vnc-0.9.14/
	./configure --prefix=/usr/local CFLAGS='-g -O2 -fno-stack-protector -Wall'
