The new life of bugs.python.org
Limited Capacity seats available

"Bugs.python.org (later called BPO) is the bug tracker supporting development
of CPython, the main implementation of Python language. During PyCon US in Portland,
OR, I was asked to help migrate the current BPO instance into a new infrastructure.
My personal recommendation was to migrate BPO onto OpenShift Online, especially
that it supports open source projects providing resources for running necessary
infrastructure bits. This presentation will be the story how I migrate legacy
BPO installation onto latest OpenShift:

1. What is bugs.python.org
a) What it is and how it's being used?
b) Current deployment details.
2. Pick up the pieces
3. Build
a) Custom builder (non-git repositories & custom process)
4. Deployment
a) Database
b) Configuration
c) Deployment
5. Tips & tricks"

Scalable cloud IDE with Eclipse Che and OpenShift
Limited Capacity seats available

"Eclipse Che is a browser-based IDE providing on-demand workspaces that include runtimes and IDEs. It is powered by a RESTful workspace server (with Docker, OpenShift of Kubernetes as underlying infra), plug-ins for languages, framework, and tools.


In this session, we will demonstrate how to boost the power of Eclipse Che with Keycloak to build a collaborative developer environment. We will also discuss how to manage teams, groups, organizations, and permissions for fine-grained access to APIs and resources.

One Testing Framework to Rule Them All
Limited Capacity filling up

"Testing your software can be even more complex than developing the software itself. You need a collection of distinct types of tests, like unittests and functional tests for every single layer, from the backend to the public API, from the Database model to the Web Interface, from the Mobile App to the Build Scripts, on local, remote, virtual or container deployments. In this session we will discuss methods and frameworks to reduce the complexity, improve the test coverage and optimize its performance.
You're expected to have some knowledge in Software Development and in Software Testing, but the session will cover the basics of the approached subjects."

Why Is CRUD a Bad Idea - Focus on Real Scenarios
Limited Capacity filling up

"Everyone knows what CRUD means - Create, Read, Update and Delete... But wait, what is actually an Update?
Does writer “update” an article or does he “publish” it?
Do customers “update” an order or do they “pay” for it?
Does your happy boss “update” your salary or does she “raise” it?
Generic CRUD approach does not represent a real-life experience and makes both your user interface and API harder to understand and maintain.
This talk covers differences between Rich Domain Model and Anemic Domain Model, their advantages and disadvantages, and how these concepts affect the design of your model, forms and user interface."

Advanced releases and custom routing in OCP
Limited Capacity seats available

"Openshift is becoming more and more relevant in the container platform and PAAS area, with many developers and organizations already using it in production to deliver large scale, mission critical apps.
In this area, some of the most appreciated and used features are related to the advanced deployment techniques.
Since Openshift can easily spawn different versions of the same application and send traffic to them , it is an obvious option to help you implement rolling updates, Blue / Green deployments, canary and so on.
In this talk, we will start introducing different techniques on how to implement content based routing, in order to have advanced routing based on request / client supplied informations. We will talk about HAproxy, Camel and Istio."

Hacker's guide to Web Assembly
Limited Capacity seats available

"WebAssembly is a new low-level binary compile format that will do a better job at being a compiler target than JavaScript. It’s being called “the future of the web platform” and did you know that its promising features in terms of speed, reusability and safety has brought major browser vendors working together to make it a reality and the MVP is already available in major browsers.

Want to know how WebAssembly work? Why is WebAssembly so fast? How to build web apps using C/C++/Rust? In this talk we’ll look at history, basics, applications and deep dive into the core concepts of WebAssembly with help of live demos and coding.

Session Content :
- Introduction to WebAssembly
- Live Demos
- History & Need of WebAssembly
- Applications of WebAssembly
- Community Details & support Channels"

Cockpit - Moving towards more advanced use-cases
Limited Capacity seats available

"Cockpit is a browser-based server adminstration user interface. One of its main goals is to make running linux servers more discoverable and usable for newcomers. However, that doesn't mean that Cockpit isn't useful for more advanced tasks—especially when quickly glancing at the health of a system or figuring out the cause of a problem.

In this talk, we'll present the progress Cockpit has made during the last year: it has grown several new features, made writing third-party modules easier than ever, and is now included in more distributions. We'll also show some of its more advanced use-cases and what we think might be good next steps to take it further into that direction.

Pythonic Apache Spark app patterns for the cloud
Limited Capacity seats available

"In this presentation Michael will demonstrate how to create and deploy Python based Apache Spark applications to cloud native environments. We will explore design patterns to help you integrate your analytics and machine learning algorithms into applications which can take full advantage of cloud native platforms like OpenShift Origin. You will see code samples and live demonstrations of techniques for building and deploying Apache Spark applications written in Python. These samples and techniques will provide a solid basis that you can use to create your own intelligent applications for the cloud."

Being a simple pagure user or just curious about this, you might have missed a few of the features that were added. We will try to go through the main ones, present the ones we are planning on and leave time for questions or live feature requests!"

Extending Cockpit with custom plugins in React
Limited Capacity seats available

"In this session, we will cover extending Cockpit (http://cockpit-project.org/), a web-based server management tool for Linux systems. Cockpit is the default administrative interface for Fedora Cloud, oVirt Node, and other distros, and can easily be added to Atomic, CentOS, and others.

Cockpit was designed to be modular, and adding your own code is a very easy process. Cockpit provides abstractions for invoking on dbus, spawning processes, and interacting with the filesystem.

We'll use docker-compose to bring up a development environment which reflects changes live, and walk through creating a filesystem browser and python REPL in about an hour.

No familiarity with React is required, though some familiarity with basic web development wold be helpful. Docker-compose should be configured."
