What forces layout / reflow

All of the below properties or methods, when requested/called in JavaScript, will trigger the browser to synchronously calculate the style and layout*. This is also called reflow or layout thrashing, and is common performance bottleneck.

Generally, all APIs that synchronously provide layout metrics will trigger forced reflow / layout. Read on for additional cases and details.

Element APIs

Getting box metrics

elem.offsetLeft, elem.offsetTop, elem.offsetWidth, elem.offsetHeight, elem.offsetParent

Download videos from egghead

Go to the egghead website, i.e. Building a React.js App

run

$.each($('h4 a'), function(index, video){
  console.log(video.href);
});

Configuring nginx for SSL SNI vhosts

Gotchas

Note that SHA2 hash algorithm may be not supported on older systems (Windows XP, Windows 2003, among others).
Be aware that mandatory https on SNI vhosts eliminate [Internet Explorer on Windows XP, among others] (http://en.wikipedia.org/wiki/Server_Name_Indication#Web_browsers.5B6.5D).

	This note explains how to build Postgres from source and setup to debug it using LLDB on a Mac. I used this technique to research this article:

	1. Shut down existing postgres if necessary - you don’t want to mess up your existing DB or work :)
