Building Database-Driven Apps with Go by Baron Schwartz

Baron Schwartz Go is rapidly becoming a popular language for server-side development, and has great support for databases built-in. But how does Go's database/sql package work? There's not much in the way of examples in the documentation; you have to kind of figure it out. But the common usage patterns are actually pretty simple (and there aren't many). I'll share what I've learned about that.

In addition, I've found a number of surprises, lightly documented things, and interesting little-known features of the database/sql package. I'll cover all of these things. If you're considering building an app that connects to a database with Go, this talk could save you some time, money, stress, and data.

Baron Schwartz is CEO and co-founder of VividCortex, a Charlottesville startup focusing on database performance management through measurement and analysis of server workload. He's the lead author of High Performance MySQL, an Oracle ACE, and speaks and writes widely on system and database performance, scalability, and capacity analysis.

Visualizing Big Data by Judy Xu

Big Data implementations allow fast storage and retrieval of huge amounts of unstructured and semi-structured data. Common data sets include genomics data, traffic data, and social media data. NoSQL databases, which are highly distributed and horizontally scalable, form the foundation of many of these implementations with MongoDB among the most widely used. But how do you make any sense of this huge treasure trove of information? With several (i.e., hierarchical or flat) methods to connect to Big Data sources, how do you choose the right way? Join us to discover how to visualize these large sets of data and how you can easily apply data visualization and analytical functionality to your Big Data, all while avoiding the pitfalls.

Hold the Lambdas! Functional Constructs in Java Today by Will Hayworth

Will Hayworth For several reasons, functional programming has become significantly more popular over the past decade--and out of every mainstream modern programming language, Java may be the most inherently hostile to it. Closures, for example, are high-overhead and seriously non-idiomatic. Java 8 promises to change this with Project Lambda--but many of us will still write code for Java 7 even after it's released.

In this presentation I'll explain that there's still a lot that functional thinking can give us in pre-lambda versions of Java. We'll demonstrate code that you can use in production right now that offers improved safety and productivity, and we'll also take a look at what's coming in Java 8.

Will Hayworth takes pride in crafting software at Lab49, where engineers create bespoke solutions for the financial services industry and where he is the proud cohost of their internal tech talk series. He enjoys functional programming and the actor model.

Vert.x - Bringing the Browser to the Cluster by Lance Ball

Lance Ball Vert.x is an asynchronous, event-driven application platform that runs on the JVM. It uses a multi-reactor event loop to achieve a very high number of concurrent connections, and is similar to Node.js in style and usage. Due to its JVM underpinnings, Vert.x is a polyglot platform, supporting several JVM languages, including Javascript, JRuby, and Clojure. Clustering is built-in and remarkably easy to use, and the Vert.x event bus makes passing messages between components or applications simple. With JSON as the native message format, and a SockJS client that speaks directly to the event bus, pushing event-based messages to the browser has never been easier.

In this talk I will introduce the Vert.x platform, provide an overview of the API, and finish up with a demo application that uses the Vert.x event bus along with Backbone.js and MongoDB to synchronize messages across a server cluster and connected browsers.

Lance Ball is a Senior Software Engineer at Red Hat and is a member of Project Odd, a group of Red Hat developers focused on polyglot open source research and development. He is a core contributor to DynJS, a new Javascript runtime for the JVM; and a core contributor to TorqueBox, a JRuby application server. For the Vert.x project, Lance maintains the Javascript language modules: mod-lang-rhino, mod-lang-dynjs, and mod-lang-js.

The Shape of Functional Programming by Michael Fogus

Michael Fogus You may have heard the news that functional programming is in and object-oriented programming is out.  Well, that's not actually true, but it's safe to say that functional programming is grabbing the attention of more and more software developers.  A rapidly growing programming paradigm, functional programming is about tackling software complexity by focusing on loosely coupled functions building up to larger-level programming abstractions.  In this talk I'll run through the basic concepts behind functional programming using JavaScript and build up to more complicated topics along the way.

Michael Fogus is the author of the book 'Functional JavaScript' by O'Reilly living in the Washington DC area performing acts of distributed simulation.  Additionally, he’s actively involved in the Clojure and Underscore.js communities.

Cloudera Search: An Introduction by Ryan Gimmy

Ryan Gimmy Cloudera Search was released as an addition to Cloudera's umbrella of big data products to give access to non-developers access to simple, full-text searching of data that has been ingested into Hadoop and/or HBase. For developers, it is a tool that can allow you/users/data scientists to search through datasets that are otherwise too large to search through by traditional means.

This talk will go over Cloudera Search's use-cases, basic architecture, and the ways in which you can interact with both it through it's API calls and UI. Knowing the basics of Hadoop and/or Solr is a bonus, but definitely not required.

Ryan Gimmy is an experienced software engineer at Altamira Technology Corporation who works on big data solutions that include Hadoop, Hive, HBase, Accumulo, ZooKeeper, Apache Blur, and Impala. When he is at home, he develops mobile apps and robotic systems. He is Cloudera developer certified, and he loves the Bash scripting language because it is cryptic enough to always be interesting.

Lean and MEAN with a Head of Steam by Jonathan Altman

Jonathan Altman In this presentation we will cover what the MEAN stack (MongoDB, Express, Angular, Node.JS) is, and go through the pieces used in building a sample application that powers a lead generation data collection form for websites. We will walk through how the MEAN components connect together to build the application, and some of the associated tools like bower, grunt, and mocha that power the development workflow.

The goal is for attendees to walk away with an understanding of how the pieces of the MEAN stack fit together to create an application, and enough information and pointers to resources to get started writing their own MEAN apps.

Jonathan Altman is a frequent speaker on open source, especially node.js and MongoDB, in the Washington DC area. He is the founder of InTheBin a company building a mobile app to help people make better recycling decisions, as well as Async IO , a software consulting and contracting company helping companies with their SaaS and webservices-driven mobile applications needs. He is also one of the co-organizers of the node.dc NodeJS meetup, and has been coding with node since 2009.

Neo4j Graph DB and the Cypher Query Language by Wes Freeman

Wes Freeman Wes will talk about modeling data in Neo4j, give some graph database use cases, and show some example queries in Cypher. Neo4j is a property model graph database with its own native graph storage. It has drivers for most popular languages. Cypher is a declarative query language designed with graphs in mind, making use of ascii-art graph pattern matching along with other SQL-like syntax.

Wes Freeman is an experienced software engineer, excited about graph databases – especially the Cypher query language, to which he is a community contributor. He created the AnormCypher Neo4j "driver" for Scala. Wes is also the DC/Baltimore Graph Database meetup group organizer.

Best Practices for Component-Based Development by Mike Hansen

Mike Hansen Usage of Java components to build applications has grown exponentially. Most applications are now composed primarily of components - 80 - 90% of an application consists of components.

Many of these components are open source components that are housed in the Central Repository, the defacto standard used by open source project teams to distribute their binaries. Recent research shows some interesting trends:

  • 13 billion components were downloaded from Central in the last 12 months.
  • 53% of survey respondents are standardizing on an open source development infrastructure stack.
  • 76% of large organizations have no control over what components are being used in software development projects

Although components help improve developer productivity so that applications can be delivered faster, if components are not managed effectively, security, licensing, and quality issues can put your organization at risk. Industry analysts and standards efforts recognize managing components as a key requirement for modern development efforts.

Join Mike to learn best practices for managing and exploiting these components. He'll discuss the current state of application development market, the promise and challenge of components, and we'll provide you with a set of best practice considerations to kick-start your component management initiative.
