Meteor - Path to the MongoDB executable in OSX

/Users/USER_NAME_HERE/.meteor/packages/meteor-tool/.1.1.10.1b51q9m++os.osx.x86_64+web.browser+web.cordova/mt-os.osx.x86_64/dev_bundle/mongodb/bin/mongo

Twitter Bootstrap - How to bind a tooltip nature to programmatically generated tooltip elements

$(document).ready(function(){

  // Bind bootstrap tooltips 

  $('body').tooltip({
    selector: '[rel=tooltip]'     

    , delay: {
      show: 50 

      , hide: 250     

    }
  });
});

This will bind static or dynamically generated items that contain a "rel" attribute with a "tooltip" value. 

This is an example, with a few extra options to consider.

  rel="tooltip"   

  data-original-title="This is the tooltip's main content, the text to display." 

  data-placement="top"   

  animation="true" 

  trigger="hover focus"   

  delay="0"

CSS - FortAwesome CheatSheet

FortAwesome.com offers a hosted custom package with a set of icons of your choice. You select your icons, publish it as a "kit", and then you get a CDN to add as a .js script to your site.

This is a cheat sheet illustrating some of the options you have... from displaying a simple icon, to enlarging, rotating and animating.

This assumes you have pre-fixed your icons with the default "fa" style, and also icon name prefix.

Basic: 
    flag
">

Larger:
    33% increase: fa-lg">
    Xx increase:  fa-2x">

Fixed width:
    fa-fw">

List icons:
   

fa-ul

">
       

fa-li

fa fa-check-square">List icons

in lists

   

Bordered and pulled:

Animated:
   

Rotated and flipped:
    fa-rotate-90"> fa-rotate-90
    fa-rotate-180"> fa-rotate-180
    fa-rotate-270"> fa-rotate-270
    fa-flip-horizontal"> fa-flip-horizontal
