Dean Edwards’ IE7

Category: IE, JavaScript

Dean Edwards wishes that IE had decent CSS support, like us all. He went out and created a package called IE7, which tries to fix the box model, add XMLHttpRequest and DOMParser nicely, etc etc. The IE7 XML Extras is modelled on the Mozilla extras. Thanks Dean!

Server to Client callback via mod_pubsub

Category: JavaScript

A common issue that we have to work around, is when we would love to have the server-side of an application, call back into the client-side (browser). Obvious examples are real-time updates of data.

Thoughts on Rich Clients and Ajax

Flying back home in style (err, Southwest Airlines) after the recent Ajax Summit, I considered the “rich client” versus web app debate. With the emergence of Ajax, its gotten harder to choose between the two. After seeing what folks are doing with Ajax at the summit, its gotten *really* harder.

Ajaxian My Google! Prediction

Google has a tradition of reinventing a service that Yahoo! already has (Gmail, Maps). I would be willing to bet that GPortal is around the corner. How will Google be able to reinvent that bad boy?
