  1. February Meeting: Blockchain - A Walk Around the Block

    February 07, 2019

    February 07, 2019

    Presented by: Mike Haggerty

    “A Walk Around the Block” – Miners and smart contracts and hard forks, OH MY!  The explosion of cryptocurrency has brought with it a host of new technology and terminology.  The first half of this presentation will focus on giving a rudimentary introduction to blockchain technology in general: how it works and why it matters.  In the second half, a specific blockchain software system – EOS.IO – will be used to standup a new blockchain network and deploy a simple smart contract written in C++.

    Mike is a software engineer with 12 years of application development experience. He has worked with non-profits, governments, and publicly traded companies on everything from initial design through to deployment and all stages in between. While Mike has endured codebases comprised primarily of VB6, he is happiest working with cutting-edge technologies such as Docker, React, Node.js, and .NET Core.

  2. January: Getting up and Running with Containers

    January 03, 2019

    January 03, 2019

    Presented by: Michael Irwin & Russ Fenn

    Being new to containers can feel like sitting in front of a firehose and trying to drink all of the water coming at you. If you feel that way, no worries! In this presentation, we’re going to dive into what containers and images actually are and some best practices around them, how to use volumes and port mappings, and how to run multi-service applications. There will be quite a few hands-on opportunities. You won’t want to miss this!


    Michael Irwin is an Application Architect at Virginia Tech who is striving to modernize how software is developed and run on campus by driving the adoption of Docker-based workloads, CI/CD pipelines, the public cloud, single-page applications, and more. As a Docker Captain and Community Leader (meetup organizer), he has the opportunity to share his expertise and experiences with others, but also learn how others are using the latest technologies. When developing, he writes code in Node, Java (Java EE mostly), and JavaScript, but actively contributes to projects written in other languages and frameworks. He’s blessed to have a beautiful wife and four fantastic daughters!


    Russ Fenn is a web application and infrastructure team leader at Virginia Tech, who manages a menagerie of container and legacy applications.

  4. November - Ron Bruintjes: Dockerizing your Windows application

    November 01, 2018

    November 01, 2018

    Presented by: Ron Bruintjes

    Containers are a great solution, but what do we do with our legacy code? We'll take a simple Windows application and transform it into a Docker image without too many changes in the application or the process.

    Ron Bruintjes is a Software Architect at Medeco Security Locks in Salem. He's been dabbling in computers professionally since 1990 in a variety of roles, and is currently concentrated on the .NET stack and SQL databases

  5. October - An Introduction to Azure Cosmos DB (including Transactional JavaScript Stored Procedures in Cosmos DB) with Kevin Hazzard

    October 04, 2018

    October 04, 2018

    Presented By: Kevin Hazzard

    Let's take a close look at Azure Cosmos DB, a planet-scale, cloud database that's HTTP-enabled at its core with a SQL API, a Table API, a Cassandra API, a MongoDB API and a Graph API. We'll cover the basics of the SQL API and look at a real-world application that'll quickly bring the utility of this database into sharp focus. Then we'll turn our attention to Cosmos DB's stored procedures, written entirely in JavaScript. Wait, what? Isn't JavaScript a hot mess to work with these days? Yes, but fear not! This isn't your browser's JavaScript. Just like Node.js, where the ecosystem plays by some reasonable rules, writing stored procedures for Cosmos DB gives you the good parts of JavaScript and keeps all the ambiguity, confusion, and conflict at bay. Better still, JavaScript in Cosmos DB stored procedures is always asynchronous and transactional which means you never have to worry about performance problems or those pesky commits and rollbacks. In this code-focused session, we'll talk about those principles and the coding practices you'll want to adopt to be productive in this environment. Even if you aren't planning on using Cosmos DB yet, I believe you'll get a lot out of the discussion.

    Kevin Hazzard is a development community leader from Richmond, VA. He was a long-time college instructor and Microsoft C# MVP. Nowadays, he's an architect for the digital marketing and sales platform of Altria, the parent company of Philip Morris USA, NuMark International, US Smokeless Tobacco and Ste.

  6. September - Brian Lanham: GraphQL, React, and GatsbyJS Ol’ Sport!

    September 06, 2018

    September 06, 2018

    Presented by: Brian Lanham

    We’ll start by learning about GraphQL and how you can use it to build ‘experience APIs’. Then we’ll build a React site consuming the GraphQL API.  Finally, we’ll do some static site generation using GatsbyJS for the site.
