This is a simplification of https://subfictional.com/2016/01/25/the-complex-reality-of-adopting-a-meaningful-code-of-conduct/ The goal is to share the knowledge in this article in simple, short language. If you have time, please read the original.
Many projects are debating accepting a Code of Conduct (CoC). Many other projects already have one.
Why is this easy for some and hard for others?

| # Multiple inheritance with Modules as an alternative to injected composition | |
| # from Sandi Metz's talk [Nothing is Something](http://confreaks.tv/videos/bathruby2015-nothing-is-something) | |
| # Like Sandi's 'direct' DI method this has behavior outside of the base class | |
| # that gets composed together. However in this gist I compose modules in class | |
| # definitions instead of injecting collaborators. | |
| # Tradeoffs between this and Sandi's version are that in this case the API consumer doesn't | |
| # have to know how to make a RandomEchoHouse (no `house = House.new(formatter: Whatever.new)`), | |
| # but also the API consumer can't make anything not already accounted for either. |

JSON, MessagePack, and Google's Protocol Buffers are all awesome. Here's how they're awesome on different client environments and how to use them on your rails env.
