    Presented by: Chuck Sailors

    Squeezing the most out of performance for modern applications isn’t as hard as many developers believe. All too often it is merely a problem of not knowing when and where to properly use design principles and framework capabilities. This session will visit some of the easy ways to get started multithreading and performing asynchronous operations in .net. We will also look at common mistakes and some best practices for getting the most out of performance when dealing with threads and tasks.

  3. October Meeting: Kevin Hazzard - Mobile Data Sync for Everyone

    October 02, 2014

    October 02, 2014


    Synchronizing data between a central database and mobile devices is difficult, especially if you have a mix of Android, iOS and Windows clients to support. Microsoft SQL Server has some great tools to make this problem much easier to solve. In this session, we'll look at SQL Change Tracking, a lightweight feature that adds versioning capability to your databases. We'll do a deep dive on how Change Tracking works internally and how you can use it to generate diff-grams that support any type of mobile client. The discussion will be code-focused, highly-interactive, fun and enlightening.

    Kevin Hazzard owns and manages Developer Journey LLC, a training and consulting firm specializing in software architecture and development. He's also a Group Principal at Linchpin People LLC, leaders in the data integration and wellness space. He's a long-time C# MVP and the author of a book entitled Metaprogramming in .NET. Kevin also serves as an elected member of his local School Board and dedicates most of his non-professional time promoting public education.

  4. September meeting: Intro to Graph databases with Neo4J

    September 04, 2014

    September 04, 2014

    Presented by: Brian Lanham

    There are many flavors of databases and contrary to popular conception, we use multiple types in every application. Hierarchical, document, and relational are all relatively commonly well-known. The property graph database is gaining increasing popularity as a replacement for relational databases. They promise increased performance, improved scalability, and greater extensibility than relational databases. In this session we will learn about property graph databases, how they are more semantic in data modeling, and how to get started using Neo4j in your application development efforts.
