Exclude node_modules and .git from Backblaze backups on Mac

Edit the file at /Library/Backblaze.bzpkg/bzdata/bzexcluderules_editable.xml.
Add these rules inside the bzexclusions tag:

<!-- Exclude node_modules. -->
<excludefname_rule plat="mac" osVers="*"  ruleIsOptional="t" skipFirstCharThenStartsWith="users/" contains_1="/node_modules/" contains_2="*" doesNotContain="*" endsWith="*" hasFileExtension="*" />
<excludefname_rule plat="mac" osVers="*"  ruleIsOptional="t" skipFirstCharThenStartsWith="users/" contains_1="/.git/" contains_2="*" doesNotContain="*" endsWith="*" hasFileExtension="*" />

Preloading data in a redux application

A redux app is a chicken and egg problem. Given a particular state, the app should render a certain thing. But... where does that state come from?

Starting from empty

Given a blank state, the app needs to rely on the URL to fetch the right data to populate the state.

In a server-side app, the initial state is determined in exactly this way. Given the initial URL, populate the state, render the app, send it to the client.

In a client-side app the situation is exactly the same, except it's totally different. On the client you have way more contextual information than just the URL. Given the URL, the current app state, a components own props and its internal state... a component must decide which data it needs loaded.

OS X 10.11 (El Capitan) / Node.js and io.js Developer Environment

Custom recipe to get OS X 10.11 El Capitan running from scratch with useful applications and Node.js Developer environment. I use this gist to keep track of the important software and steps required to have a functioning system after fresh install.

	-- create a folder for use by the script and set the path to it here
	set thepath to alias "Macintosh HD:Users:joerick:Desktop:Scratch" as text

	tell application "Photos"
	set photos to every media item of container "DateFix"
	repeat with mediaitem in photos
	tell application "Finder" to delete every item of folder thepath
	export {mediaitem} to thepath with using originals
	tell application "Finder" to set theExport to item 1 of folder thepath

	z.object({
	// valid if string or:
	optional: z.string().optional(), // field not provided, or explicitly `undefined`
	nullable: z.string().nullable(), // field explicitly `null`
	nullish: z.string().nullish(), // field not provided, explicitly `null`, or explicitly `undefined`
	});

	// type

	module.exports = {
	promisify: function (web3) {
	// Pipes values from a Web3 callback.
	var callbackToResolve = function (resolve, reject) {
	return function (error, value) {
	if (error) {
	reject(error);
	} else {
	resolve(value);
	}
