Time management is a big part of a technical presentation. You want your demos to go fast enough to keep your audience's attention, but you don't want to gloss over details and lose them. Here are a few tricks I've used when showing something command line operations at a DOS prompt.

Slides and sample code from my talk on SubSonic from the SoCal Code Camp a week ago are available here. The slides were pretty light since my talk was geared towards building some very simple sample pages on the fly.

A simple checkbox grid is often the best user interface for mapping multiple selections in multiple categories:

Any web mashups, by definition, require cross-domain calls. Those cross-domain calls may happen on the client (in the browser) or on the server. Regardless of the client technology (AJAX, Flash, Silverlight, etc.), cross domain calls on the client are always more complex that server-side cross-domain calls, and for good reason. It's tricky in AJAX, and it's downright difficult in Silverlight. You'll know that Silverlight development has become more widespread when you hear a lot more complaints about this problem.

Here are a few tricks I learned while doing my "hello world" maze game in Silverlight 1.1.

I'll be presenting a session at the San Diego Code Camp this Saturday (6/30/07) titled "Using SubSonic to built ASP.NET applications that are good, fast, and cheap". I'll do a quick overview SubSonic in general, but spend most of the time building out a website. If you're interested in following along on you laptop, be sure to grab of SubSonic 2.0.2 (the latest release)from CodePlex.
