  • Fixing slow drag and drop with scriptaculous

    Recently on a project I was working on, I was tasked with fixing drag and drop that was terribly slow.  The drag and drop was implemented with scriptaculous on a calendar system.  When you clicked an event to drag it it took about 5 seconds before the page would actually let you drag it!  This was clearly unacceptable and it has to be possible because Google Calendar is lightening fast.

  • YSlow – Helping slow web pages load faster

    This article is a continuation to my article about Firebug.  YSlow is an add-on to Firebug that helps developers determine why a site is loading slowly.

  • Firebug – A developer’s best friend

    I think a good place to start is to describe one of my favorite tools.  It’s called Firebug, it’s an add-on for Mozilla browsers.

    At work, if one of my co-workers comes to me in the J-Block and asks a Javascript or CSS question, before I even consider helping them I ask if they reviewed the styles or the Javascript in Firebug.  9 times out 10 if it’s a really easy answer, you’ll see it almost immediately with the help of Firebug.
