Welcome back Eric
What Eric has been up to since Episode 117
PurelyFunctional.tv
Grokking Simplicity
What prompted the Thoughts on Functional Programming podcast
Started from Eric’s talk at Lambdup 2017
Being told it is much easier to edit existing text than write new text
Trying to start a literature around functional programming
Figuring out the format/layout of the book
“Just imagine each page as a slide”
The target audience for the book
“Functional programming is programming without side effects”
Not being able to recommend any books on getting started with functional programming
Actions, Calculations, and Data
Actions (Impure “Function”) – Depend on when, or how many times, they are run
Side-effects also being the reason we write programs
Calculations (Pure “Functions”) – Same arguments, same answer no matter how many times you run it
Data – completely inert
Data can be interpreted in multiple ways
Other side of Data is that it requires at least some interpretation
How to help distinguish Actions from Calculations
Haskell‘s IO type containing all side-effects as brilliant
The illusion that we are not doing any mutability at the machine level
Blurry line between Actions and Calculations in some cases
Any conventions for later readers to hint at Actions vs Calculations
Selling the separation of Calculations from Actions
Spending time on showing how Actions “contaminate” Calculations
The idea that “You could abstract away the mutation”
Thinking you are going to bury and covering up the problem
“Can you construct a User from an ID without hitting the database”
Needing mocks as a possible signal of being an Action instead of a Calculation
PurelyFunctional.tv videos
Thoughts on Functional Programming podcast
Property-Based Testing videos
Beginning Property-Based Testing course
Intermediate Property-Based Testing course
Advanced Property-Based Testing course
Property-Based testing
QuickCheck
Next course likely building a web-app in Clojure
Bag of Tricks for Property-Based testing
Developing for Stateful Systems
Model-based Property testing
Taking a Stateful test to a Parallel test to a Distributed Test
