Just mention design patterns in a development setting and you may incite riot. Some dispute their taxonomy - many dismiss their utility - while others unaware of the topic entirely. So with proper expectations set I have solicited the PerCS authors to write about the various patterns.

These posts will not be high-level; they will be real-life application of patterns. They will contrast patterned design with random design. But most of all they will contain freely distributed, well patterned code.
