Functional programming is all the rage these days, and many Rubyists feel left out of all the fun. But don't despair - many of the great ideas that are coming out of the functional revolution are applicable to our Ruby code, too! In this talk we'll explore some of the ways we can make our Ruby code more functional without giving up any of the joys of object orientation. In this talk you'll see how using some functional programming concepts can make your Ruby code easier to test, easier to maintain, and easier to change!

What do trendy topics like concurrency, parallelism, data streams, laziness or back pressure have to do with our good old pipes? We'll see what!

Most developers know what pipes are and how to use them to compose commands, but there is more to them than that. Under the surface of a simple idea, they have some very interesting properties that make them very useful in way more use cases than the usual | grep whatever.

We'll explore some interesting behaviors of pipes, and how to take advantage of them in ways you might not have thought of. And we'll do it all with Ruby.
