CLI tools in Python + interesting/useful packages
You can take advantages of Python even you don't know the language!

One part of this session would be focused on useful python modules, that can be used as command line tools in your scripts - knowledge of python is not required.

By the rest of time I would like to show you subset of interesting python packages available on PyPi and how these tools can you help to avoid reinventing wheel. Ready for action? :-)

You can looking forward to a lot of demos.

Code Analysis and Distribution Profiling
Distribution profiling is a process of taking pristine upstream sources and figuring out how they fit into the distribution in an automated fashion. Native dependency profiling against Python, Ruby and JavaScript packages will be shown in a demo, that is, tracking down what header files and devel libraries are needed for even installing these packages.

All Flavors of Bundling
Bundled software is group of software packages which are distributed together. This talk is going to discuss various ways how the bundling typically looks, but it also goes to point out several not so obvious cases of bundling. The pros/cons of bundling will be discussed as well, although no ultimate answer to bundling will be given.

What you (probably) don't use in modern compilers
In this presentation, I will run down some of the features modern C/C++ compilers have and I will explain how to use them to our advantage. I'll talk about plug-ins that can use the power of compilers, libraries that compilers provide, and maybe a little bit more. I will describe some use
cases for such features and we'll go through some demos at the end of the presentation, based on the time we'll have left.

No Docs, No Commit/Merge
When development and documentation efforts are coordinated, customer satisfaction is more likely.

This theatrical skit presents both failure and success scenarios (in that order) using an extended medieval metaphor. After the skit, we explain things briefly, comparing "no docs, no commit/merge" to "no test, no commit".

The inaugural performance was part of the 2015 CCS Workshop (day 3):

What Awaits You in Python 3
Python 3 is a better language than Python 2.
Unfortunately, for most projects, "porting to Python 3" means writing code that works on both versions unchanged: a subset that is, ironically, a worse language than Python 2.7.

So, why are we doing this? What's the silver lining? What awaits you in the future – on the day when you can drop support for Python 2?

Why should you care about chained exceptions, dict views, nonlocal variables, extended unpacking, keyword-only arguments, async functions, matrix multiplication, isolated mode, or or type annotations?
How can these features help you write better programs, find bugs faster, describe your logic more clearly, and have more fun doing it?

There may be a live demo, but if it fails the talk will still work.

So you want to have a modern infrastructure
Thanks to the rise of SaaS, starting a free software project have
never been as easy than now. Yet, the proprietary nature of most services
make them quite often inflexible, and therefor unsuitable for some
kind of project, thus requiring to deploy your own infrastructure.

However, while lots of documentations exist on the web, most of them
are either outdated, incomplete or not suitable, and there is almost
no guidance on the best practices for system administration for community
project, and what kind of measure are practical and efficient
for sysadmins with less time than usual.

So this talk will explore the best practices in term of security and
deployment for a project infrastructure, from ssh security to
centralized logging and authentication, focusing on the quick
wins and explaining what will they bring to the table.

Application Development from the Users Perspective
Personas are hypothetical users which you can use when designing features for your application, to anticipate user interaction based on their goals. One of many problems in software engineering is providing consistent and easy to use user interfaces. How do you know what UI enables your users to get things done? How do you find a solution if you have conflicting interests? How do you build an interface, which doesn't leave decisions about configuration of the UI up to the user.

This talk will offer a solution to these questions by making use of personas. The talk will give an introduction to what personas are, how they can be build and how they can be incorporated in the software design process. First hand experience is shared from the recent addition of personas for Beaker (beaker-project.org)

Java EE 7 Hands-on Lab with JBoss Forge
Automating tedious user tasks can increase productivity and save you money. While there are numerous tools for the continuous integration of software, many developers still rely on hand-made shell scripts, clumsy integrated development environment (IDE) wizards, or endless Google searches for generating companion project artifacts like dependency-management settings, database and ORM configuration, simple CRUD services, test-environment setup, or deploying into the cloud. JBoss Forge fills that niche in the software-development life cycle. JBoss Forge offers: A simple, modular, easy-to-grasp model for developing pluggable components that can fit in any phase of a programmer's daily life. The ability to use any programming language, database, or server you choose. An easy, testable way to define your own tools, wizards, and extensions. In this lab, you will learn how to create a full-fledged JavaEE 7 application from scratch using JBoss Forge.This is a BYOL (bring your own laptop) session, so bring your Windows, OSX, or Linux laptop and get ready to have fun!

rdopkg: power to the packagers
I wrote rdopkg to automate boring and repetitive tasks related to RPM packaging of OpenStack *client projects and it grown to contain quite a lot of white automagic to make packagers' lives easier.

rdopkg contains functionality to easily keep RPM packages up to date with upstream while managing downstream patches in git patches branches[2] (as opposed to plain .patch files). It can easily manage downstream patches and even rebase package distgit[3] to new upstream release. It also contains utilities for managing python requirements.txt files and much more we need to package OpenStack into RDO/Fedora.

This workshop is for RPM packagers. If you maintain an RPM package that carries some patches, rdopkg will probably save you a lots of time and pain. I'll show you what conventions you need to follow in your dist-git and howto setup your repo[4] in order for rdopkg to work.

I'll demonstrate basic packaging tasks with rdopkg, especially managing patches and rebasing a package to a new upstream version. I'll provide real life examples of rdopkg-managed packages from RDO. Based on your interest, I can also dive into more fancy functionality rdopkg provides such advanced python requirements.txt management or whatever you're interested in[4].

I'll also talk about how rpkg/fedpkg sucks[5] and why I plot to create an ultimate RPM packaging framework called pwnpkg[5] and finally give the world fedpkg it deserves. Join me in the glorious packaging revolution! :)

How to build the fastest multilingual VM
How would you design and write your new language to make it awesome and fast?

Let’s assume our language design is awesome and focus on how to make it fast.
The usual approach to programming language implementation is: an AST
interpreter prototype, an AST interpreter in C++, a byte-code interpreter, and
then add a JIT compiler. But this can take decades.

This presentation will show an alternative way of creating fast programming
language implementation in a single step: Truffle AST interpreters. We'll look
at the key technologies making this possible: the Graal compiler and the
Truffle framework. Graal is a modern, dynamic, clean, JIT compiler with
aggressive speculative optimizations. It's written in Java and provides APIs
which are used by Truffle, a self-optimizing AST interpreter, to generate
highly optimized machine code for many different languages.

This will hopefully come to fruition in one of the upcoming versions of the Java platform (though definitely not 9). In this talk, I will describe what value types and generic specialization are and show them live using the Valhalla prototype. I will also briefly touch another related topic, ObjectLayout.org. During these explanations, I will repeatedly stress the importance of reference locality to application performance and illustrate the difference using a couple of small JMH benchmarks.

How a Java dev benefited from transitioning to Go
How many times, when writing yet another collection of getters and setters, you've dreamed about lightweight features available in dynamic languages? What if I tell you there's a language that combines the best of both worlds: static and dynamic typing? This language offers ease of writing code, with advanced features such as a very efficient garbage collector and support for highly-scalable software architecture, just to name a few. Have you ever wondered what all the fuss is about Go? Why top companies such as Google, Red Hat, Docker, and CoreOS, just to name a few, have chosen to develop their products (Kubernetes, OpenShift, etc.) in Go? If you answered yes to at least one of those questions, this presentation is for you. I'm going to share my experience from transitioning from a long-time Java developer to a Go-dev in mere days. That’s all the effort it took to feel comfortable in the extensive ecosystem surrounding the Go language (also known as “Go-land”). Once there, you'll be programming in an "expressive, concise, clean, efficient (...), fast, statically typed, compiled language that feels like a dynamically typed, interpreted language".

Gentle Introduction to Node.js (not only) for Java devs
Maybe you've already heard it - Node.js is becoming the new platform of choice in many development teams and production systems, known for its flexibility, simplicity and having a plethora of ready-to-use libraries. And many of us, (not only) Java developers, are curious what's in it that it drives so many people away (not only) from Java.

As an active Javaist & JavaScripter, Lukas can offer interesting perspective on what Node.js offers as an alternative to the mature Java ecosystem. So, tighten your seat bealts, it will be a wild ride!

In this session, Lukas will introduce Node.js and compare it with Java:


  • asynchronous flows / promises

  • functional programming in JS

  • parallelization

  • packaging

  • modularity

  • language features from ECMAScript 6 (also known as ES 2015)

  • differences between browser- and server-side JS

  • running JS on the JVM

  • Node.js compared to Java EE

Cython: Stop writing native Python extensions in C
Cython [1] let's you write native Python extensions in a syntax very similar to Python itself. It compiles your code to C and gives you the performance of C (or C++) while keeping the coding itself easy and Pythonistic. You can use Cython to write performance focused parts of your Python project or to create nice Python interfaces for C or C++ libraries, without the need of going mad using the Python C API.

This workshop is interned for programmers already familiar with the Python language, who have no or very small knowledge of Cython.

Assemble Business Applications with BPM Back-end
Most of the new applications and start-ups use MVP (Minimum Viable Product) concept. It is very easy to work with such applications because they know exactly what we need them for and no more. In contrast there exist complex robust applications which can do everything we can think of but they are hard to learn, slow, not effective for our particular need, using too much resources, "expensive", and so on. Into this category we can put most of the business applications from big vendors which attract as many customers as possible and which need to fit to any business.

For many years, we have had flexible solutions (SOA, BPM, microservices, etc.) to keep business logic out of our applications. However, we did not have anything like that in the presentation layer and user interfaces of web applications until recently when web components emerged, html5 imports functionality was introduced, and lastly when Polymer 1.x became production ready in May 2015.

In this talk, we will get familiar with Polymer and its elements. To assemble a business application, we will create reusable custom BPM elements which will communicate to KIE Server working as a BPM back-end where we will keep all business processes, rules, forms, and other assets. Since we won't have to pay attention to the business logic, we will use the given time to focus on the user interface which end-users value the most. Like in any web application we will need routing, forms, data binding, signaling, asynchronous calls, calling REST services, hence there are many functionalities to discover.
