124: Caching Things Anywhere with Nebulex

We wanted to go deeper on the caching library Nebulex, so we visited with the creator, Carlos Bolaños, to learn what prompted its creation. Nebulex takes a couple unique approaches to things. It supports a decorator pattern to indicate that a function should be cached without having to write the boilerplate code for reading and writing to the cache. Nebulex was inspired by Ecto, in that it supports multiple adapters to different backends like Redis, Cachex and even Horde! It also supports multiple caching strategies. It's an interesting project that aims to solve common caching challenges in new ways and we enjoyed learning more about it.
