This article explains iframe-to-iframe communication, when the iframes come from different domains. That you can do this effectively is only now becoming apparent to the community, and is now used in production by Google, Facebook, and others, and has powerful implications for the future of Ajax, mashups, and widgets/gadgets. I’ve been investigating the technique and […]

This is the first of an open series on the architecture of Shindig, the new open-source gadget/widget framework project. As mentioned here earlier, this project is building something similar to iGoogle, i.e. an environment for serving gadgets, a run-time environment for the gadgets to operate in, and a gadget container (as well as OpenSocial support). I'm [...]

Ajax, AjaxPatterns, Gadgets, OpenSocial, Shindig, Web, Web 2.0, Widgets Background Widgets are small "mini websites", typically self-contained blocks of content, on a larger web page (with Ajax Design Patterns, I referred to them by the nom du jour Portlets).

Ajax, AjaxPatterns, Gadgets, Google, Web, Web 2.0, Widgets Background A while back, I walked through a Google Gadget I made called Digg Roundup, which simply shows Digg headlines and can be customised on topic and popularity.

Ajax, AjaxPatterns, Favicon, HTML, Javascript, Web, Web 2.0 I updated the favicon library a while ago, for a couple of projects I haven't released for various reasons. Anyway, Phil asked me about it, so I thought it's a good time to package it up and release it properly. And in the process wrote up Taking Browser [...]

I've just updated my favicon library, which I first wrote about here. I'll explain more about the update in a separate post. For now, I want to talk about browser tabs. Browser tabs were introduced by Opera. Then Firefox adopted them a few years later, as did Safari. Then Microsoft stepped into the '90s with their [...]
