The above question is one I’ve gotten in my logs a couple of times. I don’t actually answer it anywhere on the site, so I figured I might as well answer it here. For some strange reason, in my mellowed old age, I’m all about helping and I haven’t written about web technologies in about a month, so it can’t hurt.

JSON Feeds For Fun and Profit Part 2 – Callbacks with Twitter
In my first exploration of the JSON data interchange format, I used it in its most basic way possible. I attached a script (from delicious) to a page and simply used the built-in object created by their implementation to generate an unordered list of my recent del.icio.us posts. While it showed how easy it is to use the O, a handy, structured, Javascript Object, provided by JSON, it didn’t really illustrate how to manipulate the page with new data after page load. That is, after all, a very now thing to do, so it’s kind of important. This article will examine how to dynamically load a JSON feed and how to get data out of Twitter and into a usable form using a callback.

JSON Feeds For Fun and Profit, Part One- Del.icio.us makes it easy
Confession time: I’ve never actually worked with a JSON feed.
No, really.
I know what you’re thinking… Yes, you’re right. I’ve built a bunch of Ajax-y components and one full blown application over the past two years.
No, in light of that it doesn’t make any sense that I haven’t used JSON before.

Display: inline-block is the bee’s knees. CSS 2.1
I was looking at the CSS 2.1 Candidate Recommendation today and notices that there’s a New ‘display’ value- ‘inline-block’. That caught my eye as I’m long actually familiar with the inline-block display value. I’ve used it a couple of times for IE-specific browser hacks and I’ve always thought it would be cool if it were picked up by Firefox. Hopefully now that it’s made its way into a candidate recommendation and, presumably a real specification, they’ll add support and then I’ll be happy- in a really nerdy way.
Oh… you want to know why?

CSS Attribute Selectors. I’d like to be able to use them.
I’m looking something like two or three years into the future to a point where I can implement a small, almost negligible upgrade to the way I serve back, next and home buttons for my galleries. Add one part coding neuroses, one part browser incompatibility and one part CSS and this article will be a small glimpse at the way I think.
This will be fun.
