A Beginner's Guide to Inter-Service Messaging
Sending and receiving messages is a common task in software.

Fedora Infrastructure has many event-driven services, we'll discuss some of the problems we encountered and their solutions. Topics include:

* How to pick the right message protocol.
* How to design a "good message". How to recover when you inevitably don't design a "good message" or when the meaning of the word "good" changes.
* Networking: centralized or decentralized?
* How to deal with lost messages. Is it bad? Should you care?

Each topic contains plenty of concrete examples from Fedora Infrastructure.
At the end of this talk, the audience should be well-equipped to not repeat the mistakes we made and instead go make new and interesting mistakes.

This talk does not require prior knowledge of any message protocols.

Desktop on an OpenPOWER system? Yes!
Dog-fooding, openness, privacy. There are various reasons why to use an OpenPOWER system as a daily desktop/workstation. Thanks to the OpenPOWER ecosystem we have the hardware now, thanks to the distributions like Fedora we have the operating system and applications. What works and what doesn't, what were or still are the challenges.

Open leadership: An invitation to all
To most people, “leadership” is a capability expected of only a select group of people and roles. But this exclusive view of leadership is antiquated and inadequate. In open source communities, leadership is a set of catalytic mindsets and behaviors that enable people to work together to create something of value. In this session, you will explore new ways to demonstrate and develop personal leadership. Gain valuable insights and take away practical tools for extending your influence and impact, regardless of your role.

Github to PyPI & Fedora releasing with release-bot
Cyborg team member, release-bot can automatically release upstream packages to Github, PyPI and Fedora. If you have a project on Github and you do periodic releases to PyPI and Fedora we'll show you how to set the bot up. Then once you want to do a new release, just fill an Github issue and release-bot takes care of the rest.

Day 1 with Fedora Silverblue
Fedora Silverblue is a variant of Fedora Workstation powered by rpm-ostree, Flatpak, and container technology. It provides fearless, transactional upgrades of your OS and a clear separation of your host and applications, but still maintains the ability to customize your host as you see fit. Would you like to learn more?

This talk will discuss the background of Fedora Silverblue and its supporting technologies, while demonstrating a live install of the OS. I’ll show you how to get up and running with Flatpaks, what it looks like to build and run containers using podman, and how to customize the base OS using package layering. We’ll demonstrate the automatic update capabilities and how you can switch to a completely different ostree-based operating system.
