In that capacity, he is a lead organizer of events like Philly Tech Week, Baltimore Innovation Week and Delaware Innovation Week. He writes about entrepreneurship and media on his blog at christopherwink.com and tweets @christopherwink. The Temple University alumnus is a bicycle commuter and resident of the Fishtown neighborhood of Philadelphia.

We are thrilled to be having Chris with us this year and we can’t wait to see each and every one of you attend and show your support on August 22nd!




Paul L. Snyder
"Functional Testing For Hard-To-Test Software Using Docker and Wiremock."

Talk Description: Unit tests are useful but myopic. Integration testing is essential but can be hard to integrate into your moment-to-moment development process. Linux containers (as made popular by Docker) make it easy to build miniature environments on your workstation that are suitable for repeatable testing of complex software environments. In this talk, we'll look at using Docker, Wiremock, and other open source tools to test important properties of your distributed systems.

Bio: Paul L. Snyder works for SunGard Consulting Services and holds a Ph.D. in computer science from Drexel University. He has interests in distributed systems and self-organizing software systems. He's a co-organizer for the Philadelphia Linux Users Group, the Philly Lambda functional programming meetup, and the Clojadelphia Clojure users group.




Chris Norton
"LVM And All its Capabilities in Linux."

Talk Description: This talk will be an overview of LVM and how it can be used in various way across your linux distribution.

Bio: Chris is an avid member of PLUG and has given several talks throughout the year. He has been using Linux off and on since 2003, but has fully embraced the FOSS ecosystem in his everyday life. Chris uses Arch Linux and a Chromebook on a daily and regular basis. He is currently employed at Coredial, LLC which hosts the PLUG north meetings.




LaMaia Cramer
"Introduction to Free and Open Source Software."

Talk Description: Where do you start? What do you want to do? What are the best replacements for common for-fee software? Let's talk about the common ones and the rare ones.

Bio: LaMaia has been an open-source enthusiast for many years. She relies heavily upon these tools for daily activities, and for occasional tasks. She is friendly and somewhat loud.




Matthew Hodgson
"Defragment All The Things With Matrix."

Talk Description (Talk 1): Matrix’ goal is to build an open ecosystem for persistent pubsub messaging using standardized pragmatic HTTP/JSON APIs that people can use for a multitude of purposes. The aim of this tutorial is to introduce and explain Matrix, and show how it can be used as a universal data fabric for liberating user data being held hostage in proprietary silos - be they IoT deployments or islands of VoIP/IM communication.

We will start by introducing Matrix's architecture and look at the open source, Apache-licensed reference client and server implementations. We will use these to get a cluster of Matrix homeservers up and running, add them to the global federated Matrix network, and demonstrate Matrix's HTTP/JSON client-server API for participating in group chat and WebRTC calling with synchronised conversation history over Matrix - effectively demonstrating a 100% opensource equivalent to Google Hangouts.

As a next step, we will demonstrate how Matrix can be used for transferring and persisting arbitrary data between devices and services by gathering IoT-data from various sensor arrays into the network, and aggregating, processing and visualising this data via Matrix's Application Service API. Finally we will tie together both human and device communications and defragment ALL THE THINGS as our grand finale.

So far, Matrix has been received positively by the WebRTC community by providing a much-needed pragmatic standardized HTTP JSON API for WebRTC call setup - winning the Audience Award at WebRTC Expo 2014 and Best Innovation Award at WebRTC Paris 2014. At OSCON we hope to reveal Matrix's larger-scale vision as a generic persistent pubsub layer for the Internet.

"Introduction To Matrix - An Open Standard For Decentralised Distributed Communication"

Talk Description (Talk 2): We believe that real-time communication is fundamentally broken and fragmented on today's internet. XMPP and SIP tried to solve this, but haven't taken off as they might have done, leaving the internet dominated by closed proprietary islands of communication like WhatsApp, Facebook, Hangouts for human communication, and a myriad different vendor silos for IoT device communication.

Enter Matrix: a set of pragmatic RESTful HTTP JSON APIs as an open standard, intended to be implemented on a wide range of servers, services and clients, letting developers build arbitrary messaging and VoIP functionality on top of the Matrix ecosystem rather than adding yet another closed/proprietary solution.

In Matrix, devices and users run Matrix clients, which connect through to a Matrix "homeserver" which stores all their communication history and user account information - much as a mail client connects through to an IMAP/SMTP server. Just like email, you can either run your own Matrix homeserver, which means you own and control your own communications and history - or you can use one hosted by someone else (e.g. matrix.org) - there is no single point of control or mandatory service provider in Matrix. In fact, there is no single point of control over communication in Matrix at all - communication history is a first class citizen, with history replicated over all participating servers, avoiding single-points of failure or control as you get in XMPP MUCs.

So far, Matrix has been received positively by the WebRTC community by providing a much-needed pragmatic standardized HTTP JSON API for WebRTC call setup - winning the Audience Award at WebRTC Expo 2014 and Best Innovation Award at WebRTC Paris 2014. But in the end, we hope Matrix will crack the problem of a widely successful open federated platform for any kind of communication on the internet, from group chat and WebRTC to IoT and anywhere else you need a common data fabric to link together fragmented silos of communication!

Bio: Matthew Hodgson is technical co-founder of Matrix.org: an early-stage not-for-profit open source project focused on solving the problem of fragmentation in current Chat, VoIP and IoT technologies. By defining a new lightweight pragmatic open standard for federation/interoperability and releasing open source reference implementations, Matrix hopes to create a new ecosystem that makes open real-time-communication as universal and interoperable as email. Matthew juggles Matrix.org with running the Unified Communications line of business within Amdocs (formerly MX Telecom), where he's been building IP telephony solutions for 12 years. He has a BA in Computer Science and Physics from the University of Cambridge.




Christopher Brown
"Making Predictions In Space And Time With Python And Spark."

Talk Description: This presentation will show how Spark and IPython notebook can be used to do analyses and machine learning on large geospatial datasets. With increasing access to real time geospatial data from devices like cell-phones, cars, and watches the ability and desire to use this data to generate predictive models is growing. The size and nature of this data creates some unique challenges when trying to build predictive models.

Using a dataset of all New York City taxi cab trips from 2013, this presentation will show how to leverage the distributed computing model of Spark to ingest spatiotemporal data, build a predictive model, and evaluate the performance of that model. The presentation will introduce how to integrate IPython notebook with spark to allow for easy, iterative development, and compelling visualizations when working with this data.

Bio: Chris Brown is a GIS software developer at Azavea where he works on geospatial applications including HunchLab - a predictive policing and crime analytics SaaS product. Prior to joining Azavea, Chris was working on a PhD in political science at the University of Pennsylvania where he developed tools to analyze the political polarization using text and speech.




Sam Halperin
"Computer Graphics As A Context For Learning And Teaching Computer Science."

Talk Description: This discussion covers research on recent computer graphics pedagogy, with a particular eye towards major themes and implementation level technologies. For example, one theme that recurs throughout the research is the need to strike a balance between engaging beginning students to continue studying computer science, and the need to provide a foundation rooted in rigorous data structures and algorithms. A second theme that recurs is the need to abstract away the complexity of systems intended for engineering (Android SDK, OpenGL), in order to use them for teaching purposes. Presented as well, are case studies from the literature that implement these and other themes.

Bio: Sam graduated from Brandeis' Rabb School of Continuing Studies with an MSE in Software Engineering in 2011 and is currently a PhD student in Computer Science at Nova Southeastern University. His past experience includes 8 years of full stack web and mobile applications development working on REST architecture applications, and nearly two years professionally mentoring new programmers.




John Riviello
"The Truth About Your Web App’s Performance."

Talk Description: The performance of your web app is obviously important. But how do you know your web app is performing well for all of your users? Out of the box tools provide us metrics, but most only provide an overall view. This case study of building the XFINITY X1 single-page web app will demonstrate what frontend performance data should you be gathering, how to gather it, and how to make sense of all that data.

Existing tools provide insight into the performance of our web applications, but there is not a single tool that gives you the full picture. You can fill these gaps by gathering performance data of your actual users. In this talk, we'll walk through the parts of the W3C Navigation Timing, High Resolution Time & User Timing recommendations that you can easily take advantage of right now to collect important metrics (with the help of Open Source software). We'll determine the "types" of users you need to focus on to understand YOUR web app, as well as what other factors could impact those individual users' experience. And we'll make sure "Average Response Time" is never the primary focus of your metrics dashboard.

Bio: John Riviello is a Distinguished Engineer and Lead Frontend Developer at Comcast where he works on the XFINITY customer websites and web apps. In his free time, he prefers surfing waves over surfing the internet.




Charles Butler
"Modeling Orchestration Service With JuJu."

Talk Description: Orchestration is a hot topic today. Juju has been tackling the issue of modeling orchestration of Service Oriented Architecture (SOA) for the past four years. In this talk we'll cover how Juju handles orchestration, how Juju can fit in to your existing stack, and demonstrate how Juju can orchestrate common deployments.

Bio: Charles Butler Is a seasoned devops veteran. Currently employed by Canonical. Charles works on the Juju data center orchestration platform as a charmer. His prior work includes building the #5 Pittsburgh PA Digital Marketing Agency: Level Interactive, and performing community Q/A with many Open Source projects.




Dave Forgac
"Writing Better Command Line Applications With Python."

Talk Description: Often the first step in automating a repetitive task is to write a command line script. Python is a great language for this because of the number of modules and packages available -- but all of the options can be overwhelming or seem like overkill. This talk will cover many of the useful Python tools available for writing command line applications and when and why you might want to use each. In this talk you will learn:
  • What makes a good command line application?
  • Options in the standard library
  • Command line parsers
  • Interface tools
  • How to decide
  • Deploying for portability
You should come away from this talk knowing how to create your own command line applications with Python and how to choose which tools to use.

Bio: Dave Forgac has been a FOSS enthusiast ever since installing Linux for the first time in the late '90s and has experience working up and down the web software stack. He currently works as a Senior Software Engineer at American Greetings in Cleveland, OH, focusing on RESTful Web APIs and Python application deployment. He has previously worked as a Linux systems administrator, automating as much as possible using FOSS tools. He lived in Wilmington, DE for 9 years and likes traveling back to the Philadelphia area to visit when he can.

When she's not speaking, writing, or shooing cats off her keyboard, you'll find her consuming APIs and IPAs.




Walter Mankowski, Phd
"What’s New In Perl 5."

Talk Description: Perl 6 has been in development for 15 years, and there's a good chance it might finally be released before the end of the year. But Perl 5 remains in active development. It's been on a yearly release schedule for the past 5 years, and the new versions are full of new great new features like defined-or, say, state variables, versioned modules, Y2038 compliance, lexical subroutines, subroutine signatures, Unicode 7.0 support, and tons of new regular expression features. If you haven't used Perl since the (first) dotcom bust, come see what you've been missing!

Bio: Walt recently finished his PhD in Computer Science at Drexel University. His dissertation was on canonical behavior patterns, which he'll be glad to explain to you if you ask nicely. Prior to grad school, he worked on high-throughput online systems at QVC and the financial industry. He also wrote code to do statistical analysis of DNA microarray data at the Wistar Institute. Walt is currently back at Drexel working as a postdoc, where he's doing computational image sequence analysis of stem cell movies.
