Load Disqus comments only on demand if you give a shit about page weight and your visitors. Even with no comments, i.e. an empty comment form, calling Disqus will load an extra 226Kb. If your page has comments this can be far higher. This Gist accompanies my blog post: http://internet-inspired.com/wrote/load-disqus-on-demand/
// Requires jQuery of course.
$(document).ready(function() {
$('.show-comments').on('click', function(){
var disqus_shortname = 'YOUR-DISQUS-USERNAME'; // Replace this value with *your* username.
// ajax request to load the disqus javascript
$.ajax({
type: "GET",
url: "http://" + disqus_shortname + ".disqus.com/embed.js",
dataType: "script",

How I do STI: Utilize descendent tracking and override model_name so they use the same URL helpers and parameters as their base class. Makes things like responders and form_for work as expected, while preserving things like to_partial_path.
class AppleRecord < Record

Big list of http static server one-liners

Each of these commands will run an ad hoc http static server in your current (or specified) directory, available at http://localhost:8000. Use this power wisely.

AppleScript and JavaScript for Automation to get frontmost tab’s url and title of various browsers.
-- AppleScript --
-- This example is meant as a simple starting point to show how to get the information in the simplest available way.
-- Keep in mind that when asking for a `return` after another, only the first one will be output.
-- This method is as good as its JXA counterpart.
-- Webkit variants include "Safari", "Webkit", "Orion".
-- Specific editions are valid, including "Safari Technology Preview".
-- "Safari" Example:
tell application "Safari" to return name of front document
