    YubiKey 4 series GPG and SSH setup guide

Written for fairly adept technical users, preferably of Debian GNU/Linux, not for absolute beginners.


You'll probably be working with a single smartcard, so you'll want only one primary key (1. Sign & Certify) and two associated subkeys (2. Encrypt, 3. Authenticate). I've published a Bash function which automates this slightly special key generation process.

                14 Simple algorithm for chromatic aberration effect in JavaScript
              
          
    Chromatic aberration effect - a simple implementation in JavaScript

A chromatic aberration is an optical effect caused by one or more color channels being displaced. Although it is an optical failure and should be avoided for displaying or image capturing devices, chromatic aberration can be used to make graphics be more realistic in some other applications like 3D games.
The following codes is an example of implementing the effect using ImageData API of HTML5 canvas. By fetching and manipulating pixel data of the image, the chromatic aberration effect is easy to achieve.
