PDX.pm July Meeting - Highly Functional Programming

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

In this week’s Design Podcast, I sit down with Jay Trimble, mission operations manager, ground data system manager, and resource prospector for the Lunar Rover Mission at NASA. We talk about applying Agile, adopting design thinking and user-centered design, and what he and his team rely on to design and build software for mission control.

In this week’s Design Podcast, I sit down with Ben Yoskovitz, investor, entrepreneur, and former VP of product at VarageSale and at GoInstant. We talk about using metrics in product development and why anyone building anything new needs to have both hubris and intellectual honesty. Yoskovitz is co-author of Lean Analytics, and is teaching a two-day course on product strategy as part of the upcoming O'Reilly Design Conference.

Spring Framework is a Java platform that provides infrastructure support for developing all kinds of Java applications. Java Spring enables you to build applications from “plain old Java objects” (POJOs) and to apply enterprise services to them. Spring capability is applied to the Java SE programming model as well as to full and partial Java EE. Java Spring Training handles the infrastructure so you can focus on your application.

This week’s podcast features a chat with Vitor Olivier. Vitor is a partner at NuBank (a technology-centric bank in Brazil). This podcast hits on topics from several of Nubank’s recent QCon talks and includes things like: Nubank’s stack, functional programming, event sourcing, defining service boundaries, recommendations on reasoning about services, tips (or tweaks) on the second iteration of their initial architecture and more.

Why listen to this podcast:

- Property-based testing and Schemas (or Clojure.Spec)are complementary.
- Clojure’s functional nature and Datomic’s features are a match for Nubank’s requirements.
 - A (micro)service needs to be able to create the full representation of the core feature it’s handling.
 - GraphQL is useful to abstract away the distributed system complexity from the mobile (or frontend) developers.
 - Nubank’s uses a combination of monitoring and sanity checks in real time at various level to keep systems consistent. 
- Once an invariant is broken, the system will try to fix it automatically.

Architecting a Modern Financial Institution with Vitor Olivier, Thoughts on Immutability, CI/CD, FP

On this week’s podcast, Wes Reisz talks with Chris Swan. Chris is the CTO for the global delivery organisation at DXC Technology. Chris is well versed in DevOps, Infrastructure, Culture, and what it means to put all these together. Today’s topics include both DevOps and NoOps, and what Chris calls LessOps, what Operations means in a world of Serverless, where he sees Configuration Management, Provisioning, Monitoring and Logging heading. The podcast then wraps talking about where he sees validating code in a serverless deployment, such as canaries and blue-green deployments.

Why listen to this podcast:

* Serverless still requires  ops - even if the ops aren’t focused on the technology
* Even with minimal functions, the amount of configuration may exceed it by a factor of three
* Disruptive services often move the decimal point
* ML is the ability to make the inferences and AI is the ability to make decisions based on those inferences

O'Reilly Media spreads the knowledge of innovators. At O’Reilly, a big part of our business is paying attention to what’s new and interesting in the world of technology. We have a pretty good record at having anticipated some of the big technology developments in recent history. For instance, we launched the first commercial Web site, GNN, in 1993; we organized the meeting at which the term “open source” was first adopted; we were early investors in Blogger, which helped launch the blogging revolution; and more recently, our Web 2.0 conference launched a world-wide meme. We call this predictive sense the “O’Reilly Radar.” And while we’re certainly not always right, we are, at least, good at making interesting guesses.

Our methodology is simple: we draw from the wisdom of the alpha geeks in our midst, paying attention to what’s interesting to them, amplifying these weak signals, and seeing where they fit into the innovation ecology. Add to that the original research conducted by our Research team, and you start to get a good picture of what the technology world is thinking about.
