Universal Rails async onPageLoad script (Turbolink v2, v5.0, v5.1, jquery-turbolinks, and no Turbolinks)

This lets you load application JavaScript asynchronously from <head>. Compatible with Turbolink v2, v5.0, v5.1, jquery-turbolinks, and no Turbolinks. Compatible with all browsers and IE9+ (only IE10+ will actually benefit from this though).

How to use this:

  1. Add the HTML snippet just before the closing </body> tag.

  2. Add the on_page_load.js script to the beginning of your application.js, and use window.App.onPageLoad(...) instead of document.addEventListener('DOMContentLoaded', ...) and jQuery(($) -> ...) everywhere.

  3. Include your JavaScript like so:

    <head>

GitHub Standard Fork & Pull Request Workflow

Whether you're trying to give back to the open source community or collaborating on your own projects, knowing how to properly fork and generate pull requests is essential. Unfortunately, it's quite easy to make mistakes or not know what you should do when you're initially learning the process. I know that I certainly had considerable initial trouble with it, and I found a lot of the information on GitHub and around the internet to be rather piecemeal and incomplete - part of the process described here, another there, common hangups in a different place, and so on.

In an attempt to coallate this information for myself and others, this short tutorial is what I've found to be fairly standard procedure for creating a fork, doing your work, issuing a pull request, and merging that pull request back into the original project.

Creating a Fork

Just head over to the GitHub page and click the "Fork" button. It's just that simple. Once you've done that, you can use your favorite git client to clone your repo or j

** Find commmonly accessed tables and their use of indexes:
SELECT relname,seq_tup_read,idx_tup_fetch,cast(idx_tup_fetch AS numeric) / (idx_tup_fetch + seq_tup_read) AS idx_tup_pct FROM pg_stat_user_tables WHERE (idx_tup_fetch + seq_tup_read)>0 ORDER BY idx_tup_pct;
Returns output like:
relname | seq_tup_read | idx_tup_fetch | idx_tup_pct
