Your turn-key Cockpit UI in a CI/CD ecosystem
Cockpit (https://cockpit-project.org) and its builtin set of UIs for system
services has become an integral part of Fedora Server, RHEL, and is included in
all major distributions.

It has always been very simple to create your own interfaces using Cockpit's
API. But it is a big step from some quick HMTL+JS proof of concept towards
maintaining a production-grade project with proper integration testing/gating
and fully automatic delivery. This talk introduces the tools and services that
the Cockpit team offers for developing your Cockpit extensions, which gets you
there right from scratch.

Make system administration boring again
APIs strive to make programmer's jobs easier by keeping stability. Less attention is perhaps being paid to stability of system configuration, where interfaces include configuration file formats and various utilities. Ansible is a great tool for system management, but keeping Ansible playbooks across major upgrades can be challenging due to those interface differences. Come to learn how we are solving this problem using standardized Ansible roles - Linux System Roles.

Attendees will gain a practical understanding of how to use Linux System Roles with Ansible to configure their Fedora, RHEL or CentOS systems consistently across multiple releases. The audience is assumed to have a basic understanding of Ansible and experience with Linux (preferably Fedora-derived) system administration.

Red Hat CoreOS and OpenShift v4
This is a follow-up to a Devconf.us talk: https://devconfus2018.sched.com/event/FNMU/container-linux-and-rhel-the-road-ahead

In this talk, we’ll look at how the DNA of Container Linux, Atomic Host, and RHEL are merging together to provide automated operating system management for OpenShift v4. Specific focus areas are Ignition, “oscontainers” (ostree-in-container), and how the machine configuration operator ties these together.

We'll demonstrate how this provides operators with automated OS updates that are tightly integrated with the Kubernetes/OpenShift experience.

Tuned - helper for system tuning
The talk will introduce Tuned and its features. Tuned is application for system tuning. It can help system administrators to optimize their systems for various workloads (e.g. SAP, Oracle DB, MS SQL, ...) or to optimize systems for general goals like high throughput, low latency, or low power consumption. Instead of having configuration on multiple places and in custom scripts, Tuned stores all its configuration cleanly in one place - in the Tuned profile. It can do do rollback of settings, supports hot plugging of devices and can be controlled from the command line or through the D-Bus, thus it can be easily integrated into existing administering solutions like e.g. Cockpit.

Auto-maintain your Package
Fedora has a specific aim, to have patches and development go upstream to their respective projects. This has been on each maintainer to do. We want to make that simple, even trivial … by using Git as God^H^H^HLinus intended.

There are many packages which use source git for development, rather than dist-git: systemd, cockpit, ostree, the RHEL kernel and more. The spec files live in the project’s source git history, often pushed upstream.

We are now working on a system to make this easily available to everyone: work with code, not tarballs and patches. We’ll show you a prototype that can easily turn on auto-maintenance of your package in dist-git, even rawhide. Have your package track upstream work automatically, when it passes tests to check that it works with the rest of Fedora.

The dangers of focusing on output vs outcome
Have you heard these phrases at work in the past three months?
1. That's now how it works here. Or, that will never work here.
2. We can't move forward until we have a better solution designed.
3. We can't make a decision until we have everyone in the room.

The expectation to deliver high-quality, feature rich software faster while inadequately addressing the pressure of that has created an environment of high stress and low reward. Trying to change decades of ingrained habits comes at an understandable technology and human cost.

In this talk, you will learn what behaviors are a result of cultures that put an emphasis on output vs. outcome, how you can mitigate them as technologists, and ultimately focus on achieving a healthy and empowered environment.

Challenges of product owner in a new agile team
Product Owners are key in any agile teams that are being formed. They are communication hubs between their teams and all of their teams' stakeholders. They are also important advisors of the team. It is these people that often take the first hit when something does not work ideally ... which happens a lot in new projects. In this session we will take a look into the life of product owners as their projects take off, what hits they take and how do they deal with them.

At the end of the session, the product owners in the audience will have some tips how to make their own lives easier. They will also know that they are not alone. The rest of the audience will have a better understanding of challenges the product owners face which will help them understand how to communicate more effectively.

Knative makes Developers Incredible on Serverless
What makes your developers incredible to develop, deploy, manage modern serverless workload? With Knative, developers can create and deploy their own serverless on Kubernetes where they want then develop your functions with your language of choice. For example, OpenWhisk has rich support for your preferred serverless apps such as Python, Java. If those languages don't suit your needs, you can deploy your own app container to act as your function. Because the containers only spin up for a function when in use, resource usage can be minimized during idle times.
In this session, you will learn how Knative makes it easier, quicker to develop, deploy, and manage your serverless app for enterprise developers with an understandable live demo.

How to Transform Dev and Test Silos into a Team
One of the foundations of lean/agile development is the elimination of waste, delay, and low customer satisfaction associated with siloed dev and test organizations. This talk describes how one software organization transformed siloed dev and test functions into unified teams focused on delivering value to customers. Attendees will learn:
-- why siloed teams are sub-optimal
-- how to plan for the transformation
-- the challenges to expect and how to overcome them
-- how the teams can evolve and grow
By presenting this information I hope to provide encouragement and a roadmap to teams facing the challenge of siloed dev and test teams, and call on them to start a transformation journey.

Processes & Tools over Individuals & Interactions
Agile nowadays might mean a lot of different things to a lot of different people. You might ask 10 times what it is, and get 10 different answers. Because of that, enabling teams to be more agile becomes even more difficult. Different perceptions, different problems and lack of understanding what really Agile is significantly contribute to misconceptions.

When thinking about Agile, some people think about : “too many meetings”, “micromanagement”, “too complex”, “not flexible enough” or ”not having the opportunity to fail”. Plus, it is impossible with remote employees.
Not only because of these perceptions, Agile gets bad reputation.

In this talk we want to share our view of what Agile is and what Agile is not based on our experience working with several teams at Red Hat.

Scale Your Auditing Events
The Linux Audit daemon is responsible for writing audit records to the disk, which you can then access with ausearch and aureport. However, it turned out that parsing and centralizing these records is not as easy as you would hope. Elastic's new Auditbeat fixes this by keeping the original configuration, but ships them to a centralized location where you can easily visualize all events. You can also use Auditbeat to detect changes to critical files, like binaries and configuration files, and identify potential security policy violations. This talk shows you what can you do to discover changes, events, and potential security breaches as soon as possible on interactive dashboards. Additionally, we are combining Auditd events with logs, which are security relevant.

Fearless Multimedia Programming
GStreamer is a popular framework of choice for multimedia programming in the Linux world. Traditionally C/C++ have been the languages of choice for writing GStreamer applications and plugins. Unfortunately, this efficiency comes at the price of safety. Even the most skilled C/C++ developers make mistakes with memory management and the results could potentially be catastrophic. Thread safety is another aspect that is central to multimedia solutions but is extremely difficult to achieve with C/C++. Rust language is designed to be both efficient and safe at the same time. In this talk, Zeeshan will present how GStreamer's Rust bindings not only make multimedia programming a lot safer, easier and fun but also allow developers to write even more efficient code than C/C++ in certain cases.

Don't write shell scripts, generate them!
Writing shell scripts is a fast way how to automate tasks within a system.
However, what does it take to write a proper script?
You have to write code that parses arguments, and a help message. Then, it is nice to have a bash completion and a man page.
Isn't it annoying that all of that is based on the same information, but you have to write it all over again in a different syntax every time?
If you want all of the above, but you don't want to repeat yourself all over again, there is a solution - the Argbash open-source script generator is there to generate everything for you in a smart way.
With Argbash on your side, you can concentrate on the added value of core functionality of your shell script without losing focus, and users of your script will appreciate a first-class user experience.

python2 will not be supported in the visible future.
However,existing script, projects need migrate to python3 while keeping compatibility with 2.
This is quite challenging work since almost all Python 2 programs require some modifications to run properly under 3.
We are working on avocado-vt and tp-libvirt projects migrating,and nearly 650 files were changed without interrupting production.
This talk will share our best practice experience and the pain points encountered:
1)Define migration strategies
2)Best Practices in idioms,including exceptions,importing,standard library numbers,dictionaries,Built-in Function change,etc...
3)Some automatic tools to help migration:sixer,2to3
4)Use virtualenv to set up validating environments
5)Special case handling: deprecated module removal

Auto-healing database for Admins and Developers
When uptime is critical, how do you build a self healing database? Let us demo how Couchbase and OpenShift can form a self-healing and fault tolerant data-as-a-service. We will fail, scale, deploy and rebalance a Couchbase Cluster with the OpenShift Operator Framework automatically. The application remains available and continues to write data without disruption. Attendees will walk away with the know-how and documentation for deploying the operator and configuring their cluster for this database-as-a-service.

We only need an internet connection.
