SICP 2.5.1&2

weekly recap message

Oh, happy day!

Is it really midweek already? Man, time flies when you're blitting bits. We had a great meeting last time with Scott moderating our conversation on generic operations as a solution to the dispatch explosion in our data-directed function table. We also discussed the interplay between type hierarchies and coercion; how those hierarchies differ from class structures in OOP; multiple inheritance, traits, mixins et al in various languages and the time complexity of finding the closest common ancestor in a DAG.

This coming Friday Leo's back in the hot seat to take us through the inner workings of a system for performing symbolic algebra (section 2.5.3). Should be a hoot!

Happy coding!
