The below configuration will pause the tour after tooltip 2 has appeared (index of 1). In the postStepCallback we check to see if the tour has been paused and fire some code.

<script>
  $(window).load(function() {
    $('#joyRideTipContent').joyride({
      pauseAfter : [1],
      postStepCallback : function (index, tip) {
        if ($(this).joyride('paused')) {
 console.log('Hey there, you\'ve paused the tour.');

Purpose and Preamble

Working With Github Pages

The FAQ maintained by Github covers most stumbling blocks, some other tips and tricks supplied here.

Gitignore

Add _site to .gitignore. The generated site should not be uploaded to Github since its gets generated by github.

Working With Code Partials

Latency numbers every programmer should know

L1 cache reference ......................... 0.5 ns
Branch mispredict ............................ 5 ns
L2 cache reference ........................... 7 ns
Mutex lock/unlock ........................... 25 ns
Main memory reference ...................... 100 ns             
Compress 1K bytes with Zippy ............. 3,000 ns  =   3 µs
Send 2K bytes over 1 Gbps network ....... 20,000 ns  =  20 µs
SSD random read ........................ 150,000 ns  = 150 µs

Read 1 MB sequentially from memory ..... 250,000 ns = 250 µs
