Content Syndication with Case-Hardened Web Badges

Everybody loves a friendly little Web badge. During this session, Kent Brewster—technology evangelist at Yahoo!, and creator of case-hardened JavaScript—will walk you through the major challenges in creating secure interactive badges that can be included in your user’s pages with a single line of JavaScript. You’ll walk in with a laptop and a network connection, and walk out with a working badge that can be immediately syndicated on your server.

Some highlights:

• Standards: we’ll use DOM manipulation only; no document.write. (Yes, these guys work on an iPhone.)
• Speed: we’ll build it with a single HTTP call; no support libraries.
• Security: we’ll anonymize it so it works without a single global variable.
• Respect: we’ll leave global events, like onload or onmouseover, for the rest of the page.
• Proxy-free: once the badge is running, we’ll communicate only between the client and the data server, for minimum bandwidth consumption.

If there’s time:

• We’ll talk about when NOT to use this method: sometimes Flash is the way to go.
• Right, this is all about broadcasting your own content. How would you go about hosting user-created badges on your own site?
