Handle CORS Client-side

Cross-origin resource sharing (CORS) is a mechanism that allows restricted resources (e.g. fonts) on a web page to be requested from another domain outside the domain from which the first resource was served. This is set on the server-side and there is nothing you can do from the client-side to change that setting, that is up to the server/API. There are some ways to get around it tho.

Sources : MDN - HTTP Access Control | Wiki - CORS

CORS is set server-side by supplying each request with additional headers which allow requests to be requested outside of the own domain, for example to your localhost. This is primarily set by the header:

Access-Control-Allow-Origin

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

So I had a sample that wasn't working in firefox. It had code like ths

"use strict";
var devicePixelRation = window.devicePixelRatio || 1;

That worked fine on Chrome but broke on Firefox with

TypeError: setting a property that has only a getter

So first thing I learned something I didn't know. Variables declared with var in the global scope

How to use terminal on Windows without going crazy…

Windows is really horrible system for developers and especially for devops. It doesn’t even have a usable terminal and shell, so working with command line is really pain in the ass. If you really don’t want to switch to any usable system (OS X, Linux, BSD…), then this guide should help you to setup somewhat reasonable environment – usable terminal, proper shell, ssh client, git and Sublime Text as a default editor for shell.

Install stuff

1. Download and install Git for Windows* with:
   • [✘] Use Git from the Windows Command Prompt

• [✘] Checkout as-is, commit Unix-style line endings

Since this is on Hacker News and reddit...

• No, I don't distribute my résumé like this. A friend of mine made a joke about me being the kind of person who would do this, so I did (the link on that page was added later). My actual résumé is a good bit crazier.
• I apologize for the use of _t in my types. I spend a lot of time at a level where I can do that; "reserved for system libraries? I am the system libraries".
• Since people kept complaining, I've fixed the assignments of string literals to non-const char *s.
• My use of type * name, however, is entirely intentional.
• If you're using an older compiler, you might have trouble with the anonymous unions and the designated initializers - I think gcc 4.4 requires some extra braces to get them working together. Anything reasonably recent should work fine. Clang and gcc (newer than 4.4, at le
