jQueryUI Tooltips are competing with Twitter Bootstrap

Both jQuery UI and Bootstrap use tooltip for the name of the plugin. Use $.widget.bridge to create a different name for the jQuery UI version and allow the Bootstrap plugin to stay named tooltip (trying to use the noConflict option on the Bootstrap widget just result in a lot of errors because it does not work properly; that issue has been reported here):

// Resolve name collision between jQuery UI and Twitter Bootstrap
$.widget.bridge('uitooltip', $.ui.tooltip);

So the code to make it work:

// Import jQuery UI first
<script src="https://stackoverflow.com/js/jquery-ui.js"></script>
// Resolve name collision between jQuery UI and Twitter Bootstrap
$.widget.bridge('uitooltip', $.ui.tooltip);
// Then import bootstrap
<script src="js/bootstrap.js"></script>

Nice copy paste code that also handles the button conflict:

<script type="application/javascript" src="https://stackoverflow.com/js/jquery.js"></script>
<script type="application/javascript" src="https://stackoverflow.com/js/jquery-ui.js"></script>
<script>
/*** Handle jQuery plugin naming conflict between jQuery UI and Bootstrap ***/
$.widget.bridge('uibutton', $.ui.button);
$.widget.bridge('uitooltip', $.ui.tooltip);
</script>
<script type="application/javascript" src="/js/bootstrap.js"></script>
