Technology Podcasts

LambdaCast is a podcast about functional programming for working developers. Our focus is to describe concepts using clear everyday language without watering anything down. If you've ever been curious about FP but were turned off by the jargon or unfamiliar concepts, this is the place to be. Thoughts, comments, critique?

6/14/2019
This time we discuss the way data tends to be structured in functional languages and some of the similarities with databases and REST.

21: Type Parameters

8/10/2018
You may have seen generics in C#, Java, or Swift but there are a lot of very useful patterns using generics that rarely get used in an OO context. In this episode, we explore Type Parameters (aka generics) from a functional perspective and how using them can improve the structure of your applications.

20: Laziness

6/18/2018
Lazy evaluation is not normally something you hear programmers discussing but there is a lot of power available if you know how to use it. This episode we'll examine the differences between lazy and strict evaluation and look at use cases for laziness. Episode 20 patrons: Marcus Nielsen Steven Loe Ted Yavuzkurt Michael Meyers Szymon Beczkowski Parl Naranja Paul Brabban Jason Sooter Show Notes: Memoization: https://codeburst.io/functional-memoization-in-javascript-adec62508bd0 Using...

18: Monads

11/16/2017
Monads, the promised land of functional programming. Or at least with all the hype they'd better be! Come join the cast as we demystify this overhyped structure that has become an indispensable part of many functional programmer's toolkits. Episode 18 patrons: Pluton Tim Buckley Huge shout out to Marcus Nielsen Show Notes: bind :: m a -> (a -> m b) -> m b Example of do syntax vs using bind aka >>=: main = do foo <- doMonadyThing foo2 <- doOtherMonadyThing foo pure (whatever foo foo2) main =...

17: Applicative Functors

8/26/2017
Building on the power of functors we examine a few scenarios where a normal Functor is problematic. Fortunately, there is a closely related structure known as an Applicative Functor that can provide the capabilities to solve a broader range of problems.

16: Functors

7/23/2017
Going deeper down the category theory rabbit hole, we explore one of the most common and useful abstractions in the functional programming world. You're likely already familiar with Functors but just didn't know it yet. Episode 16 patrons: Chris Krycho Tyler Harper George Webster Show Notes: Functor map :: (a -> b) -> f a -> f b Bifunctor bimap :: (a -> b) -> (c -> d) -> f a c -> f b d Profunctor dimap :: (a -> b) -> (c -> d) -> f b c -> f a d Phil Freeman's talk on Profunctors:...

7/5/2017
Join us as we discuss the FP community. FP has a reputation as harsh and impenetrable but is that really the case? What can you do to make FP a more inviting place? Episode 15 patrons: Chris Lopes Gabe Johnson Randy Shepherd Noel Waghorn Correction: I incorrectly stated that one of the Recurse Center Social rules was “No Feigned Ignorance” it is actually “No Feigned Surprise” Show Notes: Cloud Haskell - http://haskell-distributed.github.io/tutorials/1ch.html Recurse Center Social Rules -...

14: Dynamic and Static Languages

4/22/2017
The kind of type system a functional language uses has a large impact on the way you use that language. In this episode we discuss the tradeoffs involved in using a static or dynamic language.

Algebraic Data Types (ADTs) are one of the most distinguishing features of statically typed functional languages. Come learn why they exist, how you can use them, and how they change your design.

Into the icy maw of category theory starting with Monoids! In reality we find out it's not actually all that scary and there are some really fantastic things that we gain by understanding these basic categorical concepts. We now have a twitter account!

10: Partial Application

1/6/2017
Partial application and currying are a feature that is often mysterious to the uninitiated. Why do functional programmers care about such a seemingly useless thing? Partial application is an important part of the "FP toolkit" and we'll why and provide use cases for the importance of having partial application.

9: Polymorphism And Abstraction

12/20/2016
Abstraction takes on a different meaning amongst functional programmers. This episode we dig into how parametric polymorphism is an essential tool in developing well behaved abstractions that transcend simply being a solution to your individual problem. John Degoes polymorphism post http://degoes.net/articles/insufficiently-polymorphic When x, y, and z are great variable names http://blog.ploeh.dk/2015/08/17/when-x-y-and-z-are-great-variable-names/

8: Morphisms

11/24/2016
Oh category theory, bastion of strange and wonderful terminology, (some might say terrible and inaccessible). Love it or hate it, you're likely to run into some terms from category theory if you spend enough time in FP land. In this episode we'll tackle some of the terms that make up the 'ism family of terms, morphism, endomorphism, isomorphism, homomorphism, and catamorphism.

Recursion, that infinite spiral of self referentiality. In this episode we break down the ideas behind recursion, and more importantly when and where you might want to use recursion.

6: Null And Friends

10/10/2016
To write a program is to deal with uncertainty. Sometimes it feels like there's nothing we can count on and null (or undefined) is as pervasive as any other construct in our languages. However this does not have to be! LambdaCast dives into the thorny problem of null, and more broadly the potential for values not to exist and offers up some alternatives.
