AWS ELB with Node.js and WebSockets

This assumes that:

You are using Nginx.
You want to accept incoming connections on port 80.
Your Node.js app is listening on port 3000.
You want to be able to connect to your Node.js instance directly as well as via the load balancer.

####1. Create load balancer

Notes

This is the latest version of an email which I send periodically, offering customers the opportunity to pre-pay for SaaS in return for a discount. The benefits to the SaaS company are better cash flow and reduced churn rate. The benefits to the customer are, well, in the email. This genre of email has produced hundreds of thousands of dollars in pre-pays for some companies I work with, and it rarely requires any more work than this example.

I've put $79 is as a placeholder for the cost of the user's plan. We calculate that for each account, naturally, along with the billing contact's name.

Subject: Save $79 on Appointment Reminder (and get a tax write-off) Formatting: 100% plain text. Gmail automatically links up the central link. From: Patrick McKenzie (Appointment Reminder) [email protected]

This is a plain-text version of Bret Victor’s reading list. It was requested by hf on Hacker News.

Highly recommended things!

This is my five-star list. These are my favorite things in all the world.

A few of these works have had an extraordinary effect on my life or way of thinking. They get a sixth star. ★

	Rich Hickey on becoming a better developer

	Sorry, I have to disagree with the entire premise here.

	A wide variety of experiences might lead to well-roundedness, but not to greatness, nor even goodness. By constantly switching from one thing to another you are always reaching above your comfort zone, yes, but doing so by resetting your skill and knowledge level to zero.

	Mastery comes from a combination of at least several of the following:

	(require '[clojure.test :as test])

	; Rewrite clojure.test to generate data structures instead of writing to
	; stdout
	(def ^:dynamic results
	"Bound dynamically to an atom wrapping a vector of test report maps")

	(defn add-name
	"Given a testing report map, assoc's on a :name derived from the current
	`clojure.test/testing` context."

	(ns shades.lenses)

	; We only need three fns that know the structure of a lens.
	(defn lens [focus fmap] {:focus focus :fmap fmap})
	(defn view [x {:keys [focus]}] (focus x))
	(defn update [x {:keys [fmap]} f] (fmap f x))

	; The identity lens.
	(defn fapply [f x] (f x))
	(def id (lens identity fapply))

	# To Setup:
	# 1) Save the .git-completion.bash file found here:
	# https://github.com/git/git/blob/master/contrib/completion/git-completion.bash
	# 2) Add the following lines to your .bash_profile, be sure to reload (for example: source ~/.bash_profile) for the changes to take effect:

	# Git branch bash completion
	if [ -f ~/.git-completion.bash ]; then
	. ~/.git-completion.bash

	# Add git completion to aliases

	(ns schema->gen
	"Functions for generating test data from schemas."
	(:require [four.stateful :as four]
	[re-rand :refer [re-rand]]
	[schema.core :as sch]
	[simple-check.generators :as gen]))

	(defn ^:private re-randify-regex
	"schema requires ^$ while re-rand forbids them"

	/* Keybindings for emacs emulation. Compiled by Jacob Rus.
	*
	* This is a pretty good set, especially considering that many emacs bindings
	* such as C-o, C-a, C-e, C-k, C-y, C-v, C-f, C-b, C-p, C-n, C-t, and
	* perhaps a few more, are already built into the system.

	* BEWARE:
	* This file uses the Option key as a meta key. This has the side-effect
