Each week, we discuss a different topic about Clojure and functional programming.

If you have a question or topic you'd like us to discuss, tweet @clojuredesign, send an email to [email protected], or join the #clojuredesign-podcast channel on the Clojurians Slack.

This week, the topic is: "decomposition." We help our code through a breakup so it can find its true colors.

Our discussion includes:

How to process text and add color.
When is it time to decompose?
Return of the box mix!
How to separate transformation from I/O.
How to use reducing functions to repeat computation.
What makes code orthogonal?
The woes of packing useful data into bits.
Signs of complexity in the Java underlayer.
What is the difference between isolation and decomposition?
What are some natural points of separation?

Selected quotes:

"We are composing ourselves!"
"I'm a terminal guy, so this is all in the terminal."
"You can go look it up on the Internet. I'm not going to try to speak ANSI right now."
"The box mix makes it really easy to make a cake, but it also constricts your ability to do more things with it."
"By definition, any side effect is an orthogonal concern."
"It's screaming for decomposition!"
"Separating these out makes it so that it's easier to understand each part by itself."
"We have our 'actual code' badge again as a programming podcast!"
