Composable Templated Vectors

In this blog entry, I present a code snippet demonstrating how a templated math vector class can have a construction interface which allows it to be composed of any number of smaller or equal-dimension vector types. 1,116 more words

Detecting the Presence of a Member Function

In this blog entry, I present a code snippet to determine whether a given type contains a specific member function. The caller can indicate what types of parameters he intends on passing into the function. 1,393 more words

Code Katas

I found this post  by Jeff Atwood inspiring. I’ve always known code katas to be little self-contained programming puzzles, not unlike those algorithm questions that you prepare for your tech interviews, but it seems that they can be more “meta” than that. 485 more words
