Keynote: Who Cares if the Code is Free? User Experience & Open Source

Open source technology is now mainstream. Technologies large and small that impact people all over the world are powered by open source platforms, libraries, and backends. There’s an urgent problem, though: open source has become synonymous with shockingly poor user experience (UX). In this talk, we’ll discuss why UX design, and design in general, isn’t just fluffy stuff painted on at the end of the software development process. Rather, it’s a crucially important tool to make software freedom ubiquitous and accessible to all. You’ll learn how a UX design process works, and how you can get started (or find help) right away to improve the UX of your own software.

Tarus Balog

Tarus Balog is the founder and CEO of The OpenNMS Group, the services company behind the popular open-source monitoring software. Tarus has been involved in managing communications networks professionally since 1988, and unprofessionally since 1978 when he got his first computer—a TRS-80 from Radio Shack. Having worked as a network management consultant for many years, he was constantly frustrated in the lack of flexibility involved in commercial solutions such as OpenView and Tivoli, as well as shocked by their high prices. Looking for a better solution, he turned to open source and joined the OpenNMS project in 2001 and became principal administrator of the project in 2002. Since then he has managed not only to make a living working with free software, but The OpenNMS Group has thrived. Tarus is an outspoken evangelist for free and open source software and the communities it inspires.

Keynote: A Brief History of an Open Source Company

Most people who like open source have thought at one point or another “how can I make a living with free software?” That was my thought over fifteen years ago when I started a company around the OpenNMS open source network monitoring platform. This presentation will trace the history of that company, covering such things as how it got started and the decisions we faced concerning growth, dealing with customers, legal issues and keeping our employees happy. Oh, and making money. Kind of important to make money.

It is hoped that people can learn from our mistakes and perhaps be inspired to start their own journey into a professional life around free and open source software.

Adam Stephens

Adam Stephens is an engineering manager at CoverMyMeds, leading a cross-discipline team which focuses on infrastructure and operations improvements.

Open Source Solutions Stage: Multi Data Center PostgreSQL service discovery with Consul

With CoverMyMeds expanding to multiple Data Centers, we required a flexible solution for discovering our PostgreSQL clusters from any network location. This talk will cover how we used Consul to provide discovery of PostgreSQL master/slave nodes across all of our Data Centers, with the majority of the time being a live demo.

Aladin Gohar

Aladin has been passionate about building great teams and building transformative technology experiences for nearly 20 years. He has learned from his mistakes, always striving to improve, and attributes his successes to healthy teams.

Cleaning Up Toxic Teams and Dissolving Dysfunction

In this session, you will get a deep dive into team health topics covered in Patrick Lencioni’s books and workshops covering the 5 Dysfunctions of a Team, The Advantage, and The Ideal Team Player.

The Five Dysfunctions of a Team outlines the root causes of politics and dysfunction on the teams where you work, and the keys to overcoming them. Counter to conventional wisdom, the causes of dysfunction are both identifiable and curable. However, they don’t die easily. Making a team functional and cohesive requires levels of courage and discipline that many groups cannot seem to muster.

The Advantage provides readers with a groundbreaking, approachable model for achieving organizational health. Organizational health is about making a company function effectively by building a cohesive leadership team, establishing real clarity among those leaders, communicating that clarity to everyone within the organization and putting in place just enough structure to reinforce that clarity going forward. The model in The Advantage was originally introduced in Pat’s business fable, The Four Obsessions of an Extraordinary Executive.

An ideal team player embodies three virtues: humility, hunger and people smarts. The power this combination yields drastically accelerates and improves the process of building high-performing teams.

Alex Bandar

Dr. Alexander Bandar is an engineer by training, and an entrepreneur by accident.  Having worked ten years in the field of manufacturing software, with clients from GE to Apple to the Defense Department, he now directs the Columbus Idea Foundry – one of the world’s largest community workshops, or “makerspaces”, which he began as a passion and is now his full-time career. Having recently renovated a 60,000 square-foot factory in Columbus OH, the Idea Foundry houses tools from blacksmithing to 3D printing, teaches classes on design and fabrication, and sells memberships to anyone who wishes to use the workshop as if it were their own.  With 500+ members and growing rapidly (of whom approximately one third are entrepreneurs), the Columbus Idea Foundry is one of the most active makerspaces on the planet, has won numerous international awards in the “maker movement” arena, and is quickly finding a place in the creative, educational, technological and business ecosystems of Central Ohio and beyond.  From Los Angeles to Barcelona, Dr. Bandar speaks and consults regularly about this exciting new culture of “democratized opportunity”.

How the Open Source Movement, Digital Prototyping, and Crowd Funding Is Democratizing Opportunity

Dr. Bandar will speak on the new culture of “democratized opportunity”, which he considers to be represented by (1) free information, (2) open source software, (3) digital prototyping tools, and (4) crowdfunding.  At the nexus of these four phenomena is an empowered culture of innovation, wherein everyday people are more capable than ever to take an idea out of their head, hold it in their hand, and turn it into a product, a passion, or a business. Alex will use the backdrop of the Columbus Idea Foundry, one of the world’s largest and most active “makerspaces”, as evidence of this creative culture, and its impact on art, technology, education, and entrepreneurship.  Lastly, a route to disseminating this culture throughout the world, to strive for a planet of 10 billion educated and empowered innovators will be presented.

Alex Juarez

Alex Juarez is a Principal Engineer at Rackspace, touting 10 years with the company. Alex enjoys all things Linux, especially training and mentoring others, and has qualified to do so as an RHCA/RHCI. When Alex isn’t helping others he’s crafting killer cocktails and finding the best spots to grub in San Antonio.

Building Training Environments

Let’s talk about training. This was how the conversation started. Our goal was to put together a system that is as self-sufficient and streamlined as possible. We also wanted something we could move around and other people could use.

Using Ansible, Ansible Tower, Asciinema and some good ole Bash scripting we were able to build a platform which we think met most of our goals. I want to share with you some the work we did internally to build a training platform. There is no need to know any of the technologies; this is more of an overview where we’ll talk about concepts and the lessons learned.

Attendees will walk away with some new ideas, some knowledge of how we got around pitfalls, and hopefully a smile on their face.

A Little Artificial Intelligence Help With Syslog

The proliferation of mobile computing, PAAS, SAAS, IAAS, and virtualization has increased the burden of log file analysis for the system administration and programming function. The spike in the number of log entries has made analysis by manual human effort untenable and automated analysis essential. But effective log file analysis is not an exact science. A useful log analysis process often requires human insight and judgment. So while automated log analysis methods are useful, they must also be knowledge-based to be effective. In this talk, we describe a new Linux utility and an approach that uses autonomous epistemic agents to analyze entries in real time. The epistemic agent uses its a priori knowledge and posteriori knowledge extracted from logs. This talk provides those burdened with the task of monitoring and understanding Syslog and its variants with new Syslog configuration techniques and a preview of an AI layer proposal for Syslog.

Christopher H. Laco

Chris comes to us from the Akron, Ohio area where he’s been a programmer, webmaster, server magician and all-around jack of all trades in the industry for over 22 years.

Linux IoT Botnet Wars and the Lack of Basic Security Hardening

We will discuss the various malwares infecting Linux Internet of Things (IoT) devices including Mirai, Hajime, and BrickerBot and the vulnerabilities they leverage to enslave or brick connected devices. We will walk the audience through specific vectors they used to exploit devices and cover some basics in security hardening that would have largely protected from many of the widespread malware.

Some of the fundamental security concepts we will cover include:

  • Closing unused open network ports
  • Intrusion detection systems
  • Enforcing password complexity and policies
  • Removing unnecessary services
  • Frequent software updates to fix bugs and patch security vulnerabilities

We will also delve into the arguments and counter-arguments of vigilante hacking with Hajime and BrickerBot as examples and the potential long-term consequences in this new age of connected devices.

Working in the Open

Changing your internal model to open-by-default can take a shift in your patterns. What does it take to work in the open, for the open? I’m happy to be able to say that I work for a company that contributes back to the community directly, producing a Free and Open Source Software product that the community can use to continue the grand objective of FOSS. While I have been a part of this community for a short time, I have some insights on the change from closed to open as I re-framed my career and I would like to share those with anyone interested.

Jeff Klukas

Jeff Klukas has a background in experimental particle physics, working both as a teacher and as a researcher helping discover the Higgs boson. He is now the technical lead for the data platform at Simple, a branchless bank in the cloud. He has been a collaborator in the development of an internal PostgreSQL → Kafka change data capture pipeline (similar to Bottled Water) that has become a key foundation of Simple’s service-oriented architecture. He also has a lead role in using that pipeline to provide analysts a rich database audit trail in Simple’s data warehouse.

PostgreSQL + Kafka: The Delight of Change Data Capture

PostgreSQL is an open source relational database. Kafka is an open source log-based messaging system. Because both systems are powerful and flexible, they’re devouring whole categories of infrastructure. And they’re even better together.

In this talk, you’ll learn about commit logs and how that fundamental data structure underlies both PostgreSQL and Kafka. We’ll use that basis to understand what Kafka is, what advantages it has over traditional messaging systems, and why it’s perfect for modeling database tables as streams. From there, we’ll introduce the concept of change data capture (CDC) and run a live demo of Bottled Water, an open source CDC pipeline, watching INSERT, UPDATE, and DELETE operations in PostgreSQL stream into Kafka. We’ll wrap up with a discussion of use cases for this pipeline: messaging between systems with transactional guarantees, transmitting database changes to a data warehouse, and stream processing.

Lumina Rising: Challenging Desktop Orthodoxy

The Lumina desktop environment caused a stir in the desktop community when version 1.0 came out, primarily as it is a completely new framework and not based upon any existing desktop codebase. While Lumina targets BSD operating systems as the primary audience, portability to Linux is also a primary design goal.

As the next phase of development (version 2.0) is rapidly nearing completion, it is time to announce how the Lumina project is evolving the foundational principles behind the current generation of desktop environments. Intrinsic to their designs, the current generation of Desktop Environments have numerous flaws and limitations. Lumina is charting a new model of desktop architecture, re-imagining solutions to session security, application dependencies, message handling, and operating system integration.

Live demos of booting newly built images for OpenWrt and packaged software on a Raspberry Pi will be included.

Nikola Novakovic

Nikola got his first computer when he was 9 and immediately fell in love with it. In college he studied computer science and stumbled upon different languages and DevOps things—anything from Java to Apache and Nginx. Throughout college, Nikola started doing Ruby more and more (after watching DHH creating a blog in a couple of minutes) and landed his first Ruby gig. After that he started two of his own startups which both failed; he subsequently worked in three startups and is currently working in one early stage company. He realized his interest in business from getting involved in the startup community and has been increasingly focused on that area for the past two years. This helped him notice the non-technical skills he was missing as a software engineer.

Essential Non-Technical Skills

This talk is a sum of experience the speaker has collected working in fast paced companies as either a software developer or leading development.  It’s split up into three major parts:

Art Of Good Communication – Explains the pillars of good communication, why we need to communicate and what techniques were used to improve communication skills. It includes things like journaling, why being empathetic to others is one of the keys to good communication, and how to deal with a conversation where there is a lot of tension in the air.

Art Of Not Burning Out – Touches on a controversial topic in today’s software development/startup/DevOps world of how hard we should work and how not to burn out. It tries to explain why we burn out so often, what the real reasons behind burning out are, and how to fix it.

Art Of Getting Things Done – Explains a framework the speaker developed over the years of trying different systems, and how can you incorporate that into your workflow.

The overall goal of the talk is to raise awareness of the fact that technical skills are just a piece of the puzzle if we want to be truly successful. The intent is to give the audience tools and motivation to improve those nontechnical skills.

Patrick Tudor

Patrick Tudor is a systems engineer at the Internet Corporation for Assigned Names and Numbers in an operational role supporting ICANN’s public websites: a broad portfolio including IANA.org, ICANN.org, InterNIC.net, and example.com. Patrick lives in Los Angeles with his German Shepherd dog Jemma.

Protecting Public Websites with Apache and Linux Containers

New features in Apache 2.4 combined with Linux containers will propel your websites forward. In this talk you’ll see configurations with direct benefits for your own websites. Explore tools in Apache 2.4 to enforce common policy across diverse properties with help from containers. We will cover using Macros, If clauses, and other techniques to make a common configuration dynamic as well as protecting resources with limits by method, ACL, or via synthetic errors. Administrators who use web servers other than Apache will still gain valuable ideas from concepts presented and those who are only indirectly involved in the operation of websites will gain insight toward achieving a shared security policy and unified branding across sites. Let’s make better websites with containers and Apache.

Roberto C. Sánchez

Roberto is a practicing software engineer, Debian Developer, consultant, university adjunct instructor, and retired US Air Force officer with extensive experience in free/libre/open source, government, and commercial software development.

Secure Cloud: Linode With Full Disk Encryption

With the cloud’s increasing popularity across the business spectrum, the issue of securing data and systems deployed in the cloud has become critically important. Encryption, especially of data at rest, is a near-constant topic of discussion and of the various approaches to encryption in the cloud, each has various trade-offs. For some threat profiles, encrypting a single partition is sufficient. However, for enhanced security against physical compromise, full disk encryption (FDE) is a viable option, though one difficult to deploy in the cloud. While there are many cloud providers, this talk will discuss, step-by-step, and demonstrate how to provision a new Linode virtual server with FDE. Anyone interested in hosting services and/or data in the cloud in a secure manner will benefit from this talk. Some of the specific topics covered in the talk include:

  • Different encryption options for data at rest, including which options are offered by popular cloud providers
  • How different encryption options protect against different threats
  • The pros and cons of full disk encryption in a cloud environment
  • The types of protection full disk encryption provides and does not provide
  • A detailed HOWTO for deploying a Linode virtual server with full disk encryption
  • Unique issues associated with managing a virtual server with full disk encryption

By the end of the talk, attendees will understand how to arrive at their own decision regarding which cloud encryption option best suits their needs and will have seen a complete deployment of a Linode virtual server with FDE.

Terminal Photography

Photography? From the command line? Absolutely! Linux gives you access to your camera hardware, and plenty of interesting tools for manipulating, working with, and combining images in interesting ways once they’re captured. We’ll explore a small sample of the tools and utilities available to you for the purpose of interacting with cameras and images without involving a graphical user interface.

Steve Ovens

Steve has been working for Red Hat since December 2015 and is deployed to client sites to accomplish projects related to OpenShift. He is known for being an honest, straight-forward person who doesn’t pull punches. He has some unique insights into Red Hat’s culture as seen through the eyes of someone who has not grown up with the company.

So What is It Like to Work at Red Hat Anyways?

I’ve been working at Red Hat since December 2015. I often get asked things like “How did you get into Red Hat” or “What were you doing before” or even “How can I work for a place like that?” I’m not a marketing person, nor am I in charge of recruiting, so in this talk we’ll go over some of the common questions I hear, attempt to cut through any of the marketing and self promotion, and if there is time, cover a bit of what it is like to work solely on client sites as an OpenShift Consultant. If you want to know my honest opinion about working at Red Hat, come on out! Ask questions and get involved in the conversation.

KubeVirt, Virtual Machine Management Using Kubernetes

Kubernetes is a widely-used and extensible orchestration tool for containers. Containers and virtual machines both co-exist in the data centers of today, however there is not an open-source management solution encompassing both workloads, and this is beyond the scope of the core Kubernetes project.

The vision of the KubeVirt project is to manage virtual machines using Kubernetes as its infrastructure. Using a unified management approach simplifies deployments, allows for better resource utilization, and different workloads can be supported in an optimal way. We will cover how we are using the extensible nature of Kubernetes in a way that works well with its native patterns. This will include the current state of the project along with rationale on key decisions that led us to where we are. As with any evolving community project, there is more work to be done—we’ll spend some time discussing those gaps. This session will include a demonstration of how we currently accomplish virtual machine deployments and where we plan to go from here.
