Examples of supervision trees for `:simple_one_for_one` supervisors
defmodule SimpleSup do
@moduledoc """
This file shows methods for starting a configurable number of children under
a `:simple_one_for_one` supervisor.
When the supervision tree is first started all methods behave the same, `size`
children are started and the `:starter` returns `:ignore`. However if the
restart limit for those children is reached the `:simple_one_for_one`
supervisor will be restarted and then the `:starter`. It is possible that the
`:simple_one_for_one` is restarted successfully but the `:starter` fails to

Redux without the sanity checks in a single file. Don't use this, use normal Redux. :-)
function mapValues(obj, fn) {
return Object.keys(obj).reduce((result, key) => {
result[key] = fn(obj[key], key);
return result;
}, {});
}
function pick(obj, fn) {
return Object.keys(obj).reduce((result, key) => {
if (fn(obj[key])) {

Hang on, I'm not saying flux is dead, or that redux isn't amazing.

Okay ...

Most everybody is familiar with flux by now:

Minimalist routing in Redux

Why would you want to do this? Because you often don't need more. It's nice to not have to think about your "router" as this big special thing.

Instead, with this approch, your app's current pathname is just another piece of state, just like anything else.

This also means that when doing server-side rendering of a redux app, you can just do:

var app = require('your/redux/app')
var React = require('react')

Things that programmers don't know but should

(A book that I might eventually write!)

Gary Bernhardt

I imagine each of these chapters being about 2,000 words, making the whole book about the size of a small novel. For comparison, articles in large papers like the New York Times average about 1,200 words. Each topic gets whatever level of detail I can fit into that space. For simple topics, that's a lot of space: I can probably walk through a very basic, but working, implementation of the IP protocol.

How to migrate a Homebrew-installed PostgreSQL database to a new major version (9.3 to 9.4) on OS X. See upgraded version of this guide: http://olivierlacan.com/posts/migrating-homebrew-postgres-to-a-new-version/

This guide assumes that you recently run brew upgrade postgresql and discovered to your dismay that you accidentally bumped from one major version to another: say 9.3.x to 9.4.x. Yes, that is a major version bump in PG land.

First let's check something.

brew info postgresql

The top of what gets printed as a result is the most important:
