There are plenty of articles that explain what design patterns are, and how to implement them; the web doesn't need yet another one of those articles! Instead, in this article, we will more discuss the when and why, rather than the which and how. I'll present different situations and use-cases for patterns, and will also provide short definitions to help those of you who are not so familiar with these specific patterns.

They've broken them up by topic instead of by the patterns themselves with sections like:

• Finding the Data We Need
• Reusability
• Discover-ability
• Singularity
• Controlling Different Objects

There's also a few sections that look at other patterns that really only have a handful of uses - like the Decorator, State and Composite patterns.

The idea is simple. No more than twelve people in a workshop led by the best of the best programmers. All profits from the Client Bucket Workshops will go toward cancer research.

Their upcoming class is a look at design patterns in PHP and ActionScript happening January 13th and 14th at the City College of New York, CUNY. The price for the full two-day event (9am-4pm) is $495 USD or, if you'd only like, you can register for only one of the days - either the 13th or 14th and get in on only the PHP or only Actionscript for $285 USD . If you'd like any more information about the project or Client Bucket Workshops, see their main site here. You can also sign up for their email list if you'd like to be informed about future workshops.
