July 14th Lab : Domain Specific Languages: Hands on!

Please RSVP and note the event location.

Join us Monday, July 14th, 2014 for the special event, presented in conjunction with NashFP and Nash F#!

Location: Healthways Inc (Tech Meeting Room) 701 Cool Springs Blvd Franklin, TN 37067

In software development, we often face the same problem over and over again. For example, when designing user-interfaces, we need to specify the layout of components; when designing financial systems, we need to detect various patterns in changing prices. The Domain Specific Language (DSL) approach is to design a language for the specific problem domain and then use it repeatedly to solve multiple instances of the same problem.

In the talk-part of the meetup, we look how to think about DSLs in a functional way. This lets us focus on the domain. Rather than worrying about the syntax, we start by understanding what problems we actually want to model and what is the best way to do so. Along the way, I’ll show three DSLs – for composing 3D objects, for working with Markdown documents and for detecting live price patterns.

In the hands-on part of the meetup, you’ll get to use and extend the DSL of your choice. Do you want to create some 3D fractals using F# and add animation? Or do you want to process and render Markdown documents? Bring your laptop with Windows, Mac or Linux and F# installed – just follow the guide on www.fsharp.org!

July 10th : Clean Code: Writing Code for Humans

Join us Thursday, July 10th, 2014 for a great evening of learning and connecting with other developers. Free food and socializing starts at 6:00 PM, the lecture begins at 6:30 PM, followed by a drawing for free stuff. Everybody likes free food and free stuff, right?

Where: Vaco Training Room, 5410 Maryland Way, Suite 110, Brentwood, TN 37027

Inspired by Steve McConnel’s “Code Complete”, Uncle Bob’s “Clean Code” and Andrew Hunt’s “The Pragmatic Programmer”, this session reviews best practices for writing code in a style that’s easy to create, maintain and understand. We have a lofty goal: programming style as documentation. We’ll discuss concrete methods to get you there and give you a vocabulary for pragmatically evaluating code quality.

Various refactoring techniques, code smells, anti-patterns, and rules of thumb are discussed including fail fast, return early, separation of concerns, arrow code, magic numbers, the boy scout rule, being “stringly typed”, DRY, the stepdown rule, table-driven methods, the importance of staying native, techniques for finding subtle redundancy, reinventing the square wheel, when to create a method, doing comments right, horizontal and vertical density, and simple design patterns. Part of this session involves refactoring a confusing and ugly chunk of code into something beautiful, easy to read and maintain. While examples are in C#, coders in any language should be able to follow along and apply the principles discussed.

About Cory House

cory-house

I’m fortunate enough to love what I do. I’ve been in Kansas City designing and implementing solutions in website development and software engineering for nearly 15 years. I author online software training courses for Pluralsight and enjoy working in a wide variety of environments and languages for small businesses, large corporations, government, and out on my own doing freelance work.

I’m a C# MVP and passionate about building rich custom web apps using the latest technologies and specialize in C# .Net Web Forms and MVC, jQuery, jQueryUI, Knockout with Durandal, LINQ-2-SQL, Entity Framework, and KendoUI. While I focus on web development, I recognize there’s no silver bullet technology. I’m a believer in using the right tool for the job and I find creating apps that make life easier for others is its own reward.

June 19th Lab : Build a Customized MVC eCommerce Site in 1 Hour

Join us Thursday, June 19th, 2014 for a great evening of learning and connecting with other developers. Free food and socializing starts at 6:00 PM, and the lab begins at 6:30 PM.

Abstract

For those of us who have spent most of our careers building business applications, the prospect of creating an e-commerce storefront can be quite daunting. Not only do you have to deal with calculating tax, estimating shipping and accepting payments, but employees need a way to manage products, discounts and marketing content. Thankfully, there’s an open source e-commerce solution written in Microsoft ASP.NET MVC5 named nopCommerce that provides all this functionality and much more.

This workshop was designed to ramp everyone up on the Model-View-Controller (MVC) architecture, introduce advanced concepts used throughout the site such as Dependency Injection, and walk through the process of working with nopCommerce. By the end of the evening everyone should have first-hand experience building plugins that can be packaged and sold online.

iOS app development with Xamarin and F#

With each new release of Xamarin Studio, the mobile story gets even better for functional programming. It’s possible to write fully native, cross-platform mobile apps all entirely in F#! I’ll concentrate on iOS, covering both iOS basics and F# basics — you’ll have all the tools to run with your own idea when we’re done!

F# SQL Type Provider Deep Dive

In this deep dive Ross will take us through the new open source erasing SQL Type Provider which provides instant typed access to a variety of SQL data sources with no code generation. The provider has a pluggable back end allowing access to many SQL like data sources including Microsoft SQL Server, SQLite, Oracle, PostgreSql, MySql and MS Access.

Non-trivial type provider topics will be covered, including :

  • Overall type provider architecture and design
  • The separation and interaction points of design-time and run-time types
  • Implementation of LINQ and IQueryable in a type provider
  • The usage of Active Patterns to process Expression trees
