Topics [@1:31] Welcome Shriram Brown University PLT Scheme Family How To Design Program Bootstrap Pyret How Shriram got into programming MIT Structure and Interpretation of Computer Programs “From then, it was just like unicorns, and I’ve been in the future ever since.” Dan Friedman story Rice University Matthias Felleisen Matthew Flatt Robby Findler Why Shriram didn’t work with Matthias in Grad School Bob Harper Practical Foundations of Programming Languages Daniel Jackson Alloy Moshe Vardi Dynamic vs. Static Typing and Shriram’s view on Types Pyret as an optional typing experience Haskell Perspectives from a Programmer versus a Verification Person at heart TeJaS: Retrofitting Type Systems for JavaScript Gradual Soundness: Lessons from Static Python “We do not fully understand programmer thought processes.” “What would happen if we tried to crowd-source language design?” “Give people the language they want.” #lang typed/racket Plait language PLAI Retrofitting types systems onto existing dynamic languages Rust Pyret built with types in mind from the beginning “We want you to live in a rich world of expression, not an impoverished world […] of data types you can count on one hand.” How To Design Programs Little Schemer SICP as a magic trick “It’s almost like the dual of SICP.” “Go ahead and type. Let’s see what you can do.” Making traceability as central as possible Kathi Fisler Data-Centric Introduction to Computing Bootstrap Emmanuel Schanzer Trying to introduce computing to school Using exiting teachers to teach computing in existing disciplines Teaching students by them creating a video game as a way to teach math Kathi Fisler’s presentation at LambdaDays 2021 All of Bootstrap’s programming is purely functional Pyret as a no-research language Focus on the user experience “There are teachers that have built up a pedagogy around the use of error messages.” “I’m left-handed, and I sometimes joke it’s [parenthetical syntaxes] the same sort of thing.” Building as a language that runs in the browser for zero hassle WeScheme Tool and Language Building’s relation to Racket “If you were deeply conservative, you wouldn’t be using Racket.” Scribble LaTeX “These are the same people who, if their programming language didn’t give them separate compilation, they would just be up in arms.” Mystery Languages The Curse of Lisp The Bipolar Lisp Programmer “We have lost track of this very foundational fact, that programming is a kind of super-power. It’s the ability to make worlds and to sort-of bend things to our will, that is almost scary.” Roman Numbers #lang Racket is a language as a service FrTime Translated FrTime to JavaScript, resulting in Flapjax “Everything is a language.” RacketCon 2022 Making a pitch for “our ignorance.” As always, a giant Thank You goes to David Belcher for the logo design.

Topics [@2:32] 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’stalk 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 TSSIMPLICITY discount code for 50% off As always, a giant Thank You goes to David Belcher for the logo design.
