PipeWire: Rethinking Multimedia
Limited Capacity seats available

"PipeWire is a multimedia API that makes it easier to build distributed
real-time multimedia pipelines. It was originally built to provide shared access to
cameras but it can also be used to build a variety of multimedia services
such as a sound server. PipeWire is built on top of a new low-level plugin API (SPA for Simple Plugin API) that is designed to be simple, efficient and suitable for hard real-time processing.

In this presentation I want to talk about the design ideas, the current status
and the future plans for PipeWire."

Flatpaking your app for fame and fortune
Limited Capacity filling up

"Flatpak is a new cross-distribution, sandboxing deployment mechanism
for desktop applications. This talk will explain how you, as an
upstream developer can create a flatpak version of your application,
reaching a large audience and getting a more direct channel to your
users.

The session will start with the basics of building and distributing
flatpaks, and then cover more advanced topics like how to tweak the
sandbox to allow access to the things your app needs, and finally how
you can modify your application to work better when sandboxed without
such access."

Desktop OS of the future: ostree + flatpak
Limited Capacity full

"Endless is building a Linux desktop OS for the next billion consumers, aiming to make desktop computing practical and affordable so people can learn and create with technology.

Starting from a "clean slate" in 2012 allowed us to develop a "legacy free" Linux core OS platform using OStree from the very start, and adopting Flatpak in 2016 as it reached usability/maturity, to replace our own home-grown app bundling system.

Focusing on ostree and Flatpak, this session will detail our reasons for choosing these technologies, our experience from being early adopters in production, and the strengths, weaknesses and potential improvements we found.

A distribution approach to building Flatpaks
Limited Capacity seats available

"Flatpaks are a new way of distributing applications with bundled
dependencies so that a single binary can run across multiple versions
of a distribution and even on different distributions. While Flatpaks
are often built directly from source, building them from distribution
packages allows leveraging the distribution's existing package set and
security update process.

This talk will discuss how and why Fedora is extending its build
system to generate Flatpaks and Flatpak runtimes, how this relates to
building server-side containers and to modularity, and demonstrate the
packager-side view of the process. Attendees will learn how Flatpak
relates to the traditional distribution packaging mechanisms, and will
hopefully be inspired to help convert Fedora applications to Flatpaks."

Easy development with Docker and Openshift tooling
Limited Capacity filling up

"Container oriented development is a new way to adopt for today's developers. Although base tooling allow easy and simple deployment to be adopted, developers needs more accurate tools to deal with their day to day operations.

Based on the Eclipse Docker and OpenShift tooling, we will discover how developer tasks can be easily managed from the Eclipse IDE:
- managing containers, images
- dealing with complex deployments
- deploying and debugging local projects inside launched containers

We will walk from a simple scenario (Docker image build) to a more complex real case scenario where our application deployed on a cloud provider is remotely debugged. Everything from within the Eclipse IDE !!!"

Tao3D: Like an interactive 3D LaTeX Lisp
Limited Capacity seats available

"Tao3D (http://tao3d.sourceforge.net) is an open-source programming language for real-time interactive 3D. It is based on a functional language called XL, and uses LLVM JIT for efficient code generation.

You can use it to create interactive presentations that do not just include images or movies, but also computations, simulations, web pages or external processes. This is definitely not boring old Powerpoint.

The session will be mostly live coding, starting with the construction of simple slides and animations, all the way up to complex examples of simulation, data visualization or real-time ray-tracing shaders.

After the session, you should be able to know how to create simple presentations, and know where to look for information to create arbitrarily complex ones."

You want a Clean Desktop OS? Containerize it.
Limited Capacity filling up

"Containers are all the rage, alongside cloud and DevOps. Sometimes they also induce rage. In this talk, we will take a look at using Fedora Atomic on your desktop, when it makes sense, and what the potential benefits vs drawbacks of having a container-based OS on your desktop are for you as a developer.

You will learn:

* what Atomic Host is
* how it compares to CoreOS
* that you can use container-based OS on your desktop machine as well
* if and why that makes sense from a developer's perspective
* how to do it effectively

No maximum for attendees, no specific requirements, the talk is beginner-friendly, but some existing knowledge of containers is advised."

In this talk I'll describe what advantages Atomic Workstation has over a regular Fedora Workstation, discuss how it differs from a regular Fedora installation, talk a bit about the technologies involved (ostree, flatpak) and give an overview of the current state of affairs in Fedora 28. https://fedoraproject.org/wiki/Workstation/Atomic"

Smart Cards in Linux and why you should care
Limited Capacity seats available

"Do you want to know how Smart Cards can help you improve security and work efficiently?
Smart cards are among us for decades, but they are still not widely used on daily basis by most of us, even though they provide significant advantages for both security and usability and all the tools are open source in Linux. Smart cards are no longer only credit-card sized cards, but also more practical USB dongles which are frequently combined with other features such as OTP or U2F, which can take this even further.
I will go through architecture of smart cards and show you how they can be used to simplify your work."

Nouveau - reverse engineering Nvidia GPUs
Limited Capacity seats available

"I want to give a overview about the Nouveau project and what challenges we deal with reverse engineering Nvidia GPUs. This includes security mechanisms Nvidia added over time to their GPUs to prevent us from doing our job. Having an open source GPU driver is important, because nearly everything somebody does on their Linux driven machine goes through the graphical stack and therefore a lot of sensible information goes through it and why should we trust closed source software with our stuff? Main topics will be which parts of the graphics stack we work on, our goals, what we have achieved already, what tools we are working with to trace the Nvidia driver, how somebody interested in this project can help out, what we currently are working on and what I would like to see implemented next."

Fearless upgrades with Fedora Atomic Workstation
Limited Capacity seats available

"Fedora Atomic Workstation provides a new desktop experience powered by rpm-ostree, flatpak, and docker. There are many benefits to this combination that should make Fedora Atomic Workstation an attractive choice, some of which include:
- transactional updates: never fear updating again, even across major releases
- clear separation of host and apps: flatpaks and docker containers are updated on their own cadence and have little impact on host requirements (and vice-versa)
- other rpm-ostree features such as immutability, update rollbacks, and effortless package tracking

In this session, you will learn:
- why Fedora Atomic Workstation is awesome,
- what you can accomplish on Fedora Atomic Workstation, and
- how you can get started.

This session has no requirements."

"The past, present and future of Anaconda, the RHEL, CentOS and Fedora system installer. This presentation will try to describe significant features around the installer which have recently been released and which are being worked on for future releases.
This presentation should help you understand Anaconda’s evolution and get a glimpse into its future. I will discuss big changes to Anaconda which are coming, and take feedback and answer questions.

Attendees need to have used Anaconda before to fully understand the presentation. No deep knowledge of Anaconda is required but it is welcomed. This session could be highly valuable for those who already have some existing customizations in Anaconda."
