PDX.pm July Meeting - Highly Functional Programming

Conal Elliott, inventor of Functional Reactive Programming, tells us about the birth of FRP as well as other stories from his 25 years of functional programming experience. He shares what he considers the fundamentals of FRP (behaviors and events) and how they work in a model with continuous time. We speak about FRP practicality and efficiency, including how a continuous time model can help lead to a high performance implementation. Eventually we're led into Denotational Design, which plays a part in the design and refinement of FRP and which Conal considers his simplest and clearest design tool.

Finally, Conal gives us a teaser of his work at Tabula compiling Haskell to hardware (e.g. FPGAs).

On this episode of Eat Sleep Code, guest Dave Fancher talk about Functional Programming. We discuss how functional programming has made its way back into modern development, clean coding, and more.

Ed Charbeneau** :** Hello and welcome to Eat Sleep Code, the official Telerik podcast. I'm your host, Ed Charbeneau, and with me today is Dave Fancher.

Dave Fancher** :** Hello!

EC: And today Dave and I will be talking about functional programming in .NET. Dave is author of, The book of F#, from No Starch Press and a Microsoft MVP for .NET and also the owner of Achiiv Solutions. Dave is a Pluralsight author, and he's done a course called, "Building F# Type Providers" and he's working on a new course about functional programming with C#. So Dave what is functional programming?

DF: So ask ten different programmers what functional programming is, and you'll likely get ten different answers. But in general, they tend to boil down to three main characteristics. The first one is that functional programming is about controlling side effects, side effects are anything that changes the external state of the system. It could be as benign as writing to a log file, or it could be more nefarious like changing some shared data across the system. Under functional programming, we wanna control that as much as possible, also under functional programming, we tend to focus on expressions rather than statements, so C# tends to be statement-based. There are some expressions in there, but for the most part it's statement based, your if statements, your using statements, and so on, versus a functional language tends to be focused on expressions, rather than executing something for its effect we wanna execute something for its result. And then finally, functional programming is really centered on the idea of mathematical functions. And so functional languages want to treat functions as data. So you can pass around functions just as you would an integer or a string and that gives way to higher order functions, which is where most of the power of functional programming comes from.

EC: So you're controlling the mutability of the data in the application.

Better code with functional programming

Scala integrates features of object-oriented and functional programming. It is also a part of the JVM ecosystem, which makes it powerful and flexible. Scala is used for building Big Data pipelines in Apache Spark and it has this potential of conquering the Big Data world.

This latest MSys Podcast speaks about Scala programming language and dives deep into:

•	Why Scala Is a Popular Programming Language?
•	Pros & Cons of Scala Programming for Agile Software Development
•	Scala Use Cases
•	Using Scala and Java for Big Data Engineering
•	Importance of Scala for Big Data
•	Scala and Big Data World



About the speaker:
Mr. Vaibhav Jain is a Software Developer at MSys Technologies. He has experience in Big Data Analytics, Data Extraction, Data Analysis, Core Java and Java 8. His area of interest includes Scala, Apache Spark, Functional Programming and Virtualization.

Scala: The Next Big Thing in the Big Data World

In this episode of the O’Reilly Programming Podcast, I talk with Ken Kousen, an author, instructor, and consultant who is presenting the live online training courses Functional Programming in Java 8 and Getting Started with Spring Boot in September and October. He is also the author of the newly published O’Reilly book Modern Java Recipes: Simple Solutions to Difficult Problems in Java 8 and 9.
