After hacking on redis-lib for a bit on Sunday, I decided to write a general-purpose resource pooling library that I can re-use between it and http-easy and I recorded the process. You can check it out on YouTube:
You can find the library on GitHub. One particularly interesting bit about the library, that I did not to record, is that the tests are all property-based. I might do another screencast at some point to talk about how they work and the bugs they found in my original implementation (from the video).
