Lambda

In this first episode we discuss the big picture ideas that make functional programming distinct from other styles of programming.  No experience required! If you're interested in learning what the fuss is about, this is the episode to start with.

1: Overview Of Functional Programming

Wrapping up our grand tour of functional programming we go into more depth about the benefits of a functional first language.

2: Overview of Functional Programming part 2

This time around we'll be talking over the core benefits of FP and why you might want to consider its use in your projects.

3: Why FP?

This episode we discuss the ins and outs of higher-order functions. If you've never heard of them don't fear they're not as scary as they sound, in fact you're probably already using them!

4: Higher-Order Functions

This time we tackle the thorny issue of how you get anything done when you're not allowed to change anything. If the idea of immutability seems strange or even impossible, then we've got you covered.

5: Immutability

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.

Jonas Bonér, CTO of LightBend and creator Akka, discusses using Akka when developing distributed systems. He talks about the Actor Model, and how every Microservice needs to be viewed as a system to be successful. 

Why listen to this podcast:

 - Akka is JVM-based framework design for developing distributed systems leveraging the Actor Model - an approach for writing concurrent systems that treat actors as universal primitives and the most successful model with abstraction has been streaming
 - Circuit breakers in Akka are a backup and retry policy; they protect you by capturing failure data and allow you to roll back 
 - Every Microservice needs to be viewed as a system, it needs to have multiple parts that run on different machines in order to function and be fully resilient - thus is a Microsystem
 - Two different trends have emerged when it comes to hardware and environments: one is the trend toward Multi-core, the is a movement toward virtualized environments and the cloud
 - Saga pattern of managing long running transactions in a distributed system fits very well with messaging style architectures

Rodney Urquhart grew up in a North Philly neighborhood ridden with gang violence and effects of the crack epidemic. After seeing people around him get involved with gangs and crime, he realized that staying in high school would result in getting arrested or shot. 

At 16, Rodney dropped out of high school and moved in with his grand mother. Being a high school dropout and having no college degree, Rodney had his fair share of companies casting doubt on his ability. But his willingness to learn and work well with others was what got him to create an impressive company portfolio including Comcast, Microsoft’s Yammer, and ThoughtWorks. He didn’t just want to survive, he wanted to thrive. 

Rodney currently heads the test infrastructure team at Slack. He is also part of a program called /dev/color, a non-profit organization that aims to maximize the impact of Black software engineers in the tech space.

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.

14: Dynamic and Static Languages

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.
