Why Standardization is Critical for ARM in servers - Jon Masters, Red Hat
ARM is the most popular architecture on the planet, and isused across a wide range of mobile and embedded devices. Increasingly,there is a focus on ARM in server applications. The value of multiple vendors providing ARM powered solutions is powerful, as is the potential for fragmentation as a result. For ARM to be successful in servers, there is a strong dependency upon open, cross vendor industry standards and system level compatibility. This presentation addresses the current landscape of ARM standardization and a roadmap ahead.

You Know, for Kids! 7 Ideas for Improving Tech Education in Schools - Rikki Endsley, Red Hat
Access to technology, encouragement, mentors, and role models aren't enough. Before the tech field sees a dramatic increase in diversity, our educational system must be more inclusive. This talk is based on the article Open Letter to My Daughter’s High School Programming Teacher, which is the story of one teenager’s first programming class. Inspired by her daughter’s negative experience in the class, Rikki will discuss what what can (and often does) go wrong, and how the classroom environment can be improved dramatically without affecting staffing or budgets. This talk is based on an article that hit the front pages of Hacker News, Reddit, and Slashdot, generated thousands of comments (and dozens of private emails), and inspired lively (and heated) conversations about high school programming classes and diversity in tech: http://rikkiendsley.com/?p=256

How to Run a Collaborative Project - Lars Kurth, Citrix
Collaborative development is at the core of successful open source projects. Yet to be successful in today's competitive open source world, it is increasingly important to master many different disciplines and to develop an edge.

In this talk we will cover a wide range of topics relevant to developers and members of open source communities who want to increase participation in their projects. Topics range from growing your developer base (e.g. by participation in GSoC, OPW and similar programs), rewarding participation, projecting momentum in the media and press, coercing large companies into contributing more and in different ways to your project, running community initiatives successfully and measuring success.

We will use real-life examples and where appropriate share tools and mental models that help you make the right decisions for your project.

Stealing Chromium: Embedding HTML5 With the Servo Browser Engine - Lars Bergstrom, Mozilla & Mike Blumenkrantz, Samsung
In today's fast-paced development world, HTML5 is an emerging technology which allows for rapid, agile development with a high degree of portability. Many platforms, including Android, are incorporating HTML5 runtimes, which are essentially browser engines, as an alternative to native development. Currently, anyone wishing to embed HTML5 into their application has a very limited number of choices for a browser engine: the Apple-managed Webkit and the Google-managed Blink are the only options. There is a project which aims to create another viable option. Having begun several years ago, the Open Source Servo browser engine is written in the Rust language and is a joint research project with both Mozilla and Samsung invested. This presentation will give some background on Rust, the reasons behind Servo and its architecture, and how to use it as your HTML5 embedding engine.

Universal Tux: Accessibility For Our Future Selves - Spencer Hunley
Linux, as a whole, is advancing – and we are as well. Applications that work for us now may not be as easy to use in the future. Embracing accessibility in Linux will ensure that as we age, our systems will age with us, and will also enable people with disabilities to join the Linux community, contributing new ideas and concepts that could change the very nature of how we access technology.
This presentation will discuss what's working – and not working – for accessibility in Linux, and why it is crucial to the future of not only the Linux community, but Linux itself as well. Spencer will also address the following: the current state of accessibility in Linux; the Confinement Cycle, and how Linux's continuing evolution into mobile computing and the Internet of Things can change it; ways to 'bake-in' accessibility (and why this is needed); and why we must design for our future selves.

Hacking the Kernel, Hacking Myself - Kelley Nielsen
Outreach works! Kelley Nielsen was chosen, out of eighteen successful applicants, to be one of four Round 7 Linux kernel interns through the Gnome Outreach Program for Women. This is the story of her journey from a frustrated retail worker, dreaming of writing code for a living, to a full fledged kernel developer. More fundamentally, though, it's about the win-win situation that helped her, and can help others like her, by bringing them on board with our favorite cause--Linux.

In this presentation, Kelley will talk about the technical aspects of her project, about her participation in the OPW program, and about how she grew and changed as a coder and a person as she rose to the challenge. She will show an example of outreach and mentoring at work, and demonstrates how these activities raise the quality of the code, the coder, and the community.

Making Open Source a Priority at Spotify - Noa Resare, Spotify
Depending heavily on Open Source for the software we rely on has been the norm in tech companies for a few years now, but nevertheless it can be a challenge to make Open Source contributions a priority in our organizations.

At Spotify we love Open Source, but giving Open Source contributions the place they deserve within our tech organization has been difficult at times. In this talk we tell you all about what we have done to facilitate both contributing to upstream projects and releasing some significant internal infrastructure technology as Open Source.

This talk will give both practical tips when it comes to licensing, legal and patent issues and talk about changing engineering culture away from in house development towards a more open process. We will also give details on how we went about creating the Open Source release of Nameless, a service discovery system we built.

Empowering Your Corporate OSS Developers - Jono Bacon, XPRIZE; Karl Fogel; Leslie Hawthorn, Elasticsearch; Karsten Wade, Red Hat; Moderated by Guy Martin, Samsung
Most companies are consuming open source, but are now also hiring developers to work on open source projects that are the basis of their products. This makes sense, since having input to strategic direction in key projects is critical to innovation and business continuity. However, large organizations still struggle with cultural and procedural barriers to effective collaboration with these community projects. This panel features some of the best-known experts in the open source community discussing how you attract key open source developers to your organization, as well as 'grow' new contributors internally through adjustments to your culture and processes. The panel is moderated by Guy Martin (Senior Open Source Strategist, Samsung), with Jono Bacon (Senior Director of Community, XPRIZE), Karsten Wade (CentOS Engineering Manager, Red Hat), Karl Fogel (Community Author, Developer, Consultant) & Leslie Hawthorn (Community Manager, Elasticsearch).

Open Source in Storage: Is It Here To Stay - Nithya Ruff, SanDisk

There was an important article in Forbes late last year asking the question “why has open source not taken over Storage”.  The article went on to say that Open Source was more computer science than engineering that was needed to support mission critical storage. Nithya will take a deeper look at the transformation that is happening in storage and examine the question of the role of open source in storage. She will also look at the drivers driving growth and adoption of open source in storage as well as the state of open source supply.

Why You Should Consider Using btrfs, Real COW Snapshots and File Level Incremental Server OS Upgrades Like Google Does - Marc Merlin, Google
The presentation will give you everything you know to get up to speed with btfrs, why you should want to trust your data to btrfs, how it offers a lot of what ZFS offers without the licensing problems, as well as best practices for using it. I will go into: - the basics of administration of a btrfs filesystem - How btrfs, swraid, dmcrypt, and lvm fit or don't fit together - how to work with a single storage pool and create all your partitions from it without having to ever resize them, or require LVM as a slow and somewhat unreliable block layer. - how to have virtually as many snapshots as you want and why you really want this - how to do very efficient block level backups of changes only and much faster than rsync ever will - how those block backups can be used to deploy OS upgrades at the file level like I explained in my talk on how Google maintains its many servers last year.

Getting the Most Out of Your Code With Help From the Compiler - Thiago Macieira, Intel
Traditionally, supporting new processor instructions required writing assembly code. Those days, processors are very complex and maintaining assembly code by hand is a hard and tedious task, not to mention that processors evolve and getting the timings right of each generation is better left to the compiler. A little known feature of the compilers is that it is possible to get access to certain instructions from high-level C and C++ code. Yet modern compilers can offer more functionality to help the bold developer write better code. This presentation will present those techniques and show which ones work on GCC, Clang and the Intel compiler. It will also show how to get more information on which intrinsics exist and what they do. It will draw heavily upon the presenter's experience implementing this very type of optimisations for Qt 5.3.

Tux On Top: Open Source at the Top of the Rack - John W. Linville, Red Hat
Enterprise packet switching hardware has continued to be a hold-out against open source in the data center. The reasons for this include many of the same, tired, old arguments used in earlier fights around open source. But, at least part of the issue has been that such devices have traditionally included an under-powered CPU complex where modern Linux was just not practical anyway.

For a variety of reasons, designs are appearing that couple modern packet switching hardware with CPUs comparable to those used in contemporary server machines. Couple that with efforts like the Open Compute Networking Project, and the possibilities for open source networking infrastructure in the datacenter starts to look like a real possibility.

How would such a box look? What would we do with it? What should we do to get it? These are the questions this talk intends to address.
