IE7 CSS Pseudo Selector Slowdown?
Have you ever experienced major slowdown using IE7? It may NOT be memory related. I came across this issue while working on a bug for GameSpot. Users were complaining that the user experience was lagging. It’s more noticeable with the forums, where the users would drag the scroll bar in long threads, but the page [...]
Aaron Newton’s Event Delegation for MooTools
I just learned of Aaron Newton’s Event.Delegate.js and think it is amazing. Why is it amazing? Event delegation is a common practice where by you attach an event listener to a parent object to monitor its children rather than attach events to all the children. It’s far more efficient when you have numerous items on [...]
MooTools: No Sizzle
This is a little late.. I had forgotten to post this up on Dec. 7, 2008. Haven’t heard? Valerio Proietti of MooTools posted on their blog that Sizzle will not be implemented/adopted and reasons why MooTools, and other frameworks besides Dojo and jQuery, should not.

My friend Mike Horn asked me to come up with a solution for a pseudo selector in MooTools that John Resig wrote about for jQuery. To sum it up, the pseudo selector basically grabs the element that “has” or contains the passed-in element. After taking a look at that I came up with something.
CSS Best Practice #3: Clear Floated Containers (with Height||Width and Overflow)

Implement Other Selector Engines (e.g. Sizzle or Peppy) into MooTools?
Not too long ago announcements of two new selector engines came on the scene, Peppy by James Donaghue and Sizzle by John Resig. At the time I had a fleeting thought of how cool it would be if MooTools was as fast or faster than Peppy and Sizzle. Yesterday, Ajaxian tells us that the Dojo [...]
Solution to Flash and Select Drop-downs Covering HTML Elements
I’ve positioned elements absolutely and had to deal with a bug where the element appears below a flash object or select drop-downs, which usually occurs in IE. I’ve seen a few solutions, which work great, and I have one more to add.
