Functional Design in Clojure episodes:

February 21, 2020Ep 068: Static on the Line
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: "Serving static assets." We tease apart the layers involved in serving static assets and are surprised by how many we find.
Selected quotes:
"You'd think that serving up plain old files would be nice and simple."
"MIME types are an explosion of complexity."
"Simplicity is the only remedy for complexity. Abstraction is not a remedy for complexity."

February 14, 2020Ep 067: Handling Handler's Handles
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: "Resource management for web handlers." We manage to find a way to get our handlers the resources they need to get real work done.
Selected quotes:
"Let's get some work done in these web handlers!"
"The handler needs a handle."
"Handlers do not live on a desert island, alone."

January 31, 2020Ep 066: Compose the Codec
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: "Making middleware to handle JSON." We reinvent the wheel, and along the way discover a few reasons why you might want to do so as well.
Selected quotes:
"Ring's choice: all of HTTP is a function."
"Every concern is a function you compose in."
"It's like a bucket brigade with the request."
"Solving JSON encoding and decoding is a cross-cutting concern."

January 24, 2020Ep 065: Stuck in the Middle
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: "Ring middleware." We find that the middle is a very good place to start when almost everything is composed functions.
Selected quotes:
"It's all fun from Ring on up!"
"I want to have more than one handler."
"We want to build up different scenarios declaratively."
"The way you compose functions together is by building a function that takes functions and returns functions."

January 17, 2020Ep 064: Put Ring on It
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: "Ring, the foundation of Clojure HTTP" We focus on the bedrock abstraction for all Clojure web applications and marvel at its simplicity.
Selected quotes:
"Somebody wants to make a web app, and suddenly they're up against all these layers."
"The law of leaky abstractions is good to remember."
"HTTP is just a function call over the Internet."
"Your function gets a map, and it returns a map."

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: "HTTP and the Web of Complexity." We launch a new series and immediately get tangled in the many layers that make up the web.
Selected quotes:
"Clojure has several ways of getting to the web."
"There really are a lot of layers."
"There are a lot of bad requests out there."
"For all the decodings, there is an encoding."

Selected quotes:
"2020 is the year of perfect hindsight."
"Even we are surprised at what we recorded."
"Mutation is like weak bricks in your solution tower, they could fail you at any time."
"The Twitter API is just a whole bag of side effects."
"Programming without I/O is just warming your room."
"Not everything does all the things perfectly in all the ways."
"Complexity really is the killer in long term projects."

December 27, 2019Ep 061: Transcendental Transformations
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: "Transducers." We unpack transducers and find a familiar pattern that enables freedom from collections.
Selected quotes:
"The humble sequence. It is a mighty abstraction."
"Your reducing function can get more abstract by passing in the reducing function that handles producing the result."
"This is mind-bending enough, it's worth saying again in a different way."
"We have a function that returns a function that returns a function!"
"The cool thing about reducing functions is that they're not about collections. They are about reduction."

December 20, 2019Ep 060: Reduce Done Quick
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: "Reducers." We look at clojure.core.reducers and how it extracts performance by composing reducing functions.
Selected quotes:
"The seq abstraction, it's rather lazy."
"It's amazing how much work laziness requires."
"It doesn't work out as well. That's a wonderful way of saying 'wrong'."
"Because ease of use was a design goal, they're pretty easy to use."

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: "Sequences." We examine the sequence abstraction and then ponder how it helps and hinders our data transformation.
Selected quotes:
"There is only one filter, map, and reduce. They need to be able to interpret all collections."
"Primitives only take you so far."
"The first thing is the first thing!"
"The seq abstraction is foundational to Clojure core."
"The into function pours a sequence back into a concrete data structure."
