Hi All, I'll be giving two talks at SD West in March, one about template metaprogramming, and another called "Inside the Boost Libraries," where I plan to discuss some of the more interesting Boost internals. You can see a synopsis at http://www.cmpevents.com/SDw5/a.asp?option=G&V=3&id=271893 I'm trying to decide exactly what to cover there. I've listed some of my ideas below, but I'm obviously not familiar with the entire Boost codebase, so I thought I'd solicit suggestions. Thoughts, anyone? My ideas: * Discuss the design of shared_ptr/weak_ptr. While not exactly an implementation technique, the design is fiendishly clever and worth exploring. * The use of template-generated polymorphism in Boost.Function to combat virtual function bloat * The way that Boost.MPL uses partial specialization on template template parameters to peel apart lambda expressions and turn them into metafunction classes. * Something Boost.Python does to avoid doing dynamic lookup of argument converters based on parameter types for each wrapped call. * Something Boost.Python does to dynamically build a chain of exception handlers. * ... your ideas here ... :) -- Dave Abrahams Boost Consulting http://www.boost-consulting.com
