Over time, the KDE community has seen many people join and leave, as with any opensource community, which means that very few people in the current community still know about the initial culture. Many of the mantras and jokes from the very old days didn't make it to these days, and this presentation is an attempt at sharing more of the initial KDE culture to the current generation. Beyond the possibly surprising way that development was done at the time (for instance, do you know what was used before subversion? CVS. And before CVS?), it is particularly interesting to realize that many of the things in the architecture that we consider fixed and unchanging now, were subject to a much greater amount creativity back then. Maybe this presentation will encourage the current community to be creative again in these areas?

Since then it has grown into little community comprising of contributors. KDE India has been regularly organising conf.kde.in, annual gathering of KDE contributors in India. This talk will recount the journey of 10 years that KDE India community took from the first ever BoF to where it is at this day. In this talk, I will talk about the 10 years of KDE India journey. I will quickly tell the audience how the KDE India community was born. This talk will elaborate what kind of issues we faced during the initial days and how we solved it. This talk will discuss how new friends were made and old friends came to help in the time of need. We will discuss how the KDE e.V. was always watching us from far away and never let KDE India fail. This talk will definitely discuss how the community plugged itself into other events by doing talks, workshops or even mini-conferences at other conferences. This led to the idea of conf.kde.in and how that materialised. We will discuss how the community has been doing conf.kde.in with its limited resources. This talk will also show case how some entities like Janastu has been helping KDE India since half a decade with our finances. Similarly it will talk about other friends who have helped through out the journey. This talk will also touch upon the current state of the KDE community in India and what are the possible directions it can go in coming years. We will try and touch the topic of contributor strength and attrition in India. If time permits, would like to take up any other issues or questions from the audience. https://conf.qtcon.org/assets/qtcon.jpg pradeepto Video 2016-09-02T13:30:00+02:00 13:30 00:10 C01 c01_-_2016-09-02_13:30_-_linux_perf_for_qt_developers_-_milian_-_352 Creative Commons by SA false Perf tools for developers targeting Linux Tooling 60min Are you a Qt developer and do you use Linux as your development platform of choice? Then this talk is for you: I will introduce you to perf, the Linux tool suite for performance analysis. The talk will not only cover a broad part of what perf has to offer, it will also dive into details in how it is applicable to Qt developers in particular. Afterwards, you will know how to use perf to find CPU hotspots in your code as well as some tricks to profile wait times for lock contention issues or disk I/O. Linux perf is a tremendously powerful tool suite for performance analysis: It can do basically everything, from CPU sampling profiling to tracing of syscalls or even dynamic tracepoints in your own code. While perf is powerful, it is also quite complex and hard to master: Currently, it consists of more than twenty tools, most of which often require custom configuration to get conclusive results. Thus, newcomers have a hard time overcoming the steep learning curve. This talk aims at shortcutting this process by lying the foundation for any user-space developer to get started with Linux perf. We will cover the basic ways to profile CPU hotspots and dive into some more involved tricks to investigate lock contention or latency issues. Finally, an introduction to custom profiling and data evaluation with Python scripting will be given. While most parts of this talk will be interesting to any user-space developer on Linux, we will also cover some parts where Linux perf and Qt work particularly well together. https://conf.qtcon.org/assets/qtcon.jpg milian Video Linux perf for Qt Developers 2016-09-02T14:45:00+02:00 14:45 00:10 C01 c01_-_2016-09-02_14:45_-_gammaray_-_vkrause_-_364 Creative Commons by SA false Taking a deep look into your Qt application Tooling 60min GammaRay is a high-level runtime introspection tool for Qt applications. In this talk we will look at a number of real-world debugging and profiling problems and how the capabilities provided by GammaRay help you with those. When creating applications we strive to use higher-level frameworks to obtain results quickly and reduce development effort and long-term maintenance cost. This however provides a few challenges during debugging and profiling. With conventional instruction-level tools we have to have a reasonable deep understanding on the implementation of the frameworks we use to interpret the results correctly. Tools with understanding of the frameworks we use mitigate this problem, GammaRay is such a tool for Qt. After a brief introduction on how to use GammaRay we will look at a number of debugging and profiling examples covering a wide range of Qt features such as signals/slots, Qt Quick, widgets, state machines, model/view or Qt3D, and see how GammaRay can help in addressing these. All examples are based on real-world problems KDAB engineers encountered in their daily work, and aim at giving you an idea on how GammaRay can help with problems you might encounter in your Qt application. https://conf.qtcon.org/assets/qtcon.jpg vkrause Video Slides 2016-09-02T16:15:00+02:00 16:15 01:00 C01 c01_-_2016-09-02_16:15_-_qt_3d_and_physics_based_rendering_-__-_397 Creative Commons by SA false OpenGL and 3D 60min Physics Based Rendering (PBR) is the latest and greatest trend in real-time rendering yielding much more visually believable images than the traditional Phong or ad-hoc lighting models. The underlying concept is that the shaders should use physical principles in the encoded models - chief of which are conservation of energy and the Fresnel effect. PBR is used in many AAA game titles but here we will show how to make use of it with Qt 3D as it is widely applicable to many other types of 3D content such as for use within engineering and visualization. In this talk we will cover how to go take your raw 3D meshes, look at how to prepare textures suitable for use with a PBR-based workflow and how to feed these into a Qt 3D application. Along the way, we will explain how Physics Based Rendering works and how its formulation helps convince the brain of its realism without destroying performance. We will also take a look at some techniques that are often used in conjunction with PBR such as ambient occlusion and parallax mapping. Time permitting we will look briefly at how to add some post-processing effects to your Qt 3D renderer setup. Physics Based Rendering is a family of techniques for simulating how light interacts with surfaces. It can be applied in both offline renderers such as path tracers used in the production of television and film VFX, and more importantly for us, in real time rendering systems such as Qt 3D. There are two main groups of PBR techniques that fall under the Metal-Roughness and Specular-Glossiness workflows. This talk will concentrate on the Metal-Roughness workflow. We will show all the tooling required to take simple 3D meshes, uv-unwrap and export them for use in specialized texturing tools that can then be used to generate the images needed to feed into PBR GLSL shaders. In addition to the material textures, we will also show how to process HDR environment maps to allow high quality specular reflections to be calculated in real time. The talk will explain how all of these assets work together to produce convincing results. We will also provide tips on reducing the overall memory usage by using modern GPU facilities for managing textures. https://conf.qtcon.org/assets/qtcon.jpg .

Despite Qt has great support for development on all modern operating systems, we decided to use embedded web browser to show UI using modern web frameworks like React, while having all business logic in C++. In this talk I would like to present architecture of JetBrains Toolbox application. We created initial version of JetBrains Toolbox application during 48-hours Hackathon. Given such tight time constraints we needed UI framework that would be easy to develop and improve. At that moment we already had a number of rich web applications based on UI library speaking our design language. It was a natural choice to adapt this interface for desktop application. We combined the best of both worlds: core business logic written in C++ works stable and fast, UI in HTML/JS gives aesthetic pleasure. And Qt Framework not only provides lots of useful primitives for C++ coding, but also effectively glues both parts together. However, it requires a responsible team to achieve high quality level and smooth experience on all operating systems. I will show how we develop, build, maintain and support this application and discuss pros and cons of chosen approach. I will share best practices we use to release fast and error free. https://conf.qtcon.org/assets/qtcon.jpg .

However, some challenges remain which can be resolved with particular design of the ViewModel objects. Implementing a standalone QML UI is easy and quick. When complexity grows, it can make sense to move some parts of the implementation to C++, using QObject subclasses with Q_INVOKABLE and Q_PROPERTY macros to interface to QML code. That can work well, particularly when the lifetime of those QObjects is compatible with QML object lifetimes. In this scenario, the C++ QObjects have a role of Model or ViewModel, in an MVVM design. However, when the Model in the design does not use Qt, or when the lifetime or ownership concepts used for Model objects don't correspond well to QML ownership semantics, things get more complex. This talk explores some of the possible solutions and variables in the design space to create a maintainable, declarative and testable ViewModel layer to interface between a non-Qt Model and a QML View. https://conf.qtcon.org/assets/qtcon.jpg steveire Video 2016-09-02T13:30:00+02:00 13:30 00:30 B07+B08 b07_b08_-_2016-09-02_13:30_-_a_short_guide_to_writing_terrible_qml_-_d_ed_-_421 Creative Commons by SA false Best practices 30min QML is very easy to write. But is it easy to read? It can be; but with the lack of forced types, scoping and private members, it's easy to fall into bad practices. This talk covers the common QML anti-patterns that make your code incredibly difficult for your colleagues to edit. KDE is in somewhat of an unique position with regards to writing software. We have code tens of years old being edited by hundreds of different people who have never met trying to acheive a constantly evolving goal.. In Plasma I've seen (and been part of) many people making their first steps in QML and have started to note what works well, and what appears to work, but tends to lead to problems down the line. https://conf.qtcon.org/assets/qtcon.jpg d_ed Video 2016-09-02T14:00:00+02:00 14:00 00:30 B07+B08 b07_b08_-_2016-09-02_14:00_-_magic_with_qt_-_nessaa_-_408 Creative Commons by SA false Animations can create magic, So Let's see this Magic in Qt QtQuick 30min Animations are the heart of softwares, There are different types of animations in Qt to create different type of effects.

This seems like the last time anyone cared about it - it lives in Qt Core, but nothing in Qt Core uses it. And more importantly, nothing in Qt Core is able to create a new QFuture instance. We can not even model our own asynchronous operations with QFutures, since this requires using private classes in Qt. In the first part of this talk, we will cover the potential improvements to the QFuture class that would bring it on par with the similar classes for C++ like boost::future and Folly Future, and with similar classes in other programming languages. We will mostly talk about the potential API improvements, as well as different usage patterns in which QFuture might be a useful class if only we could actually use it. In the second part of the talk, we will briefly show the experimental AsynQt library which allows easier creation and composition of asynchronous operations based on QFuture. https://conf.qtcon.org/assets/qtcon.jpg ivan|home Video 2016-09-02T16:15:00+02:00 16:15 01:00 B07+B08 b07_b08_-_2016-09-02_16:15_-_qt_project_status_-_lars_-_354 Creative Commons by SA false The Qt Chief maintainer talks on where Qt is heading in the future In depth 60min A talk on the current state of Qt and what are seen as the big directions where Qt is going.

Both approaches have shortcomings we learned to deal with. Qml to the rescue! There has been effort to make it easy to create stunning presentations in Qml. In my opinion it has the potential to not only make presentations easier to create, but also to unleash new possibilities. I came to this conclusion after I made the presentation of my master thesis with Qml. In my talk I want to share my experience with you, enable you to quickly get started with presentations in Qml and show briefly what is possible by giving examples. <b>Native QML Location API for Web developers </b> JavaScript developers are increasingly looking for APIs which allow them to build native apps.  Esri’s QML API allows these developers to use their JavaScript skills to build Location-enabled apps leveraging the capabilities of the device.  This talk highlights the importance of native apps built purely in QML and JavaScript. <b>End Users and QML in Rolisteam</b> Technical challenges is all the reason why some people work on open-source or free softwares. At least, this information is true for Rolisteam and its team. Let me tell you all the challenges we have been faced when we wrote the character sheet system in Rolisteam. QML has been chosen to carry this feature and the main goal was to let users make their own character sheets. Is it possible for end user to write QML code ? Yes, with some tools and a good approach. Now, Rolisteam's users are QML (assisted) developers. <b>Large Traces in QML Profiler</b> The QML profiler tracks everything that happens in QML and QtQuick.

So far Qt was allowing you to integrate with Open GL fairly easily, but managing the rendering code itself was still a very challenging task. That's why Qt 5.7 will provide a new module named Qt 3D. In this talk we will cover the basics of its API. In particular, we will highlight how it eases the creation of 3D scenes, but we'll also point out that it is a full simulation engine and as such can do much more than 3D rendering. Since writing 3D code from scratch can be very difficult and since getting the architecture of your rendering engine right is critical to your application, Qt 3D will offload those risks from you so that you can focus on your actual simulation and 3D scene content. In this talk, we will cover the basics of Qt 3D's API. In particular it is structured around an Entity Component System (ECS) architecture which will be introduced. We will also present how to add geometries and materials to your scene or how to deal with user's input. If time permits, we will also cover the integration between Qt 3D and Qt Quick. This talk will be interesting to any developer having to implement a 3D scene inside an application using Qt.

The talk will look at the different requirements and implementations of automating functional HMI tests as well as visual verifications of system tests. To test a Qt or QML application there are many different test types, such as unit tests, functional tests, non-functional tests, system tests, integration tests, etc., which can and should be done. Each of these test types focus on different aspects of the testing and are complementary to each other. Several of the mentioned test types can be partially of fully automated. In this talk you will learn about all challenges of automating the functional HMI testing and visual verifications of system tests of Qt and QML user interfaces on embedded, desktop and mobile platforms.

This talk will explain the various metrics from Statement Coverage to Modified Condition/Decision Coverage (MC/DC), depict their strengths and drawbacks and show how to deal with the challenges posed by Qt C++ and QML code. Software safety standards like ISO 26262 (road vehicles), EN 50128 (railway applications) an DO-178 C (airborne systems) and others require software developers to ensure software quality through analysis of code coverage achieved through their tests. Among other measures. This talk will define what this metric means and - equally important - what it does not mean. Standard levels measured are statement coverage, branch coverage, decision coverage and the more complex modified/condition decision coverage (MC/DC) or multiple condition coverage (MCC). We'll look at the advantages and drawbacks of these levels and what kind of testing efforts they require. Qt applications pose several special challenges for measurement of code coverage: first, usage of the Meta Object Compiler (MOC), the User Interface Compiler (UIC) and various macros leads to automatically generated code that can sometimes be hard to fully cover. Secondly, the language QML includes both static declaration and dynamic JavaScript code. Above topics will be illustrated through some live demonstrations with different tools. The automated Qt tests will serve as a relatively large real-world example for viewing test coverage. Based on selected spots in the code we'll investigate gaps in current QA measures. Dynamic analysis like code coverage has to be distinguished from static analysis. Nevertheless, some classic static code metrics will be listed as their monitoring is also recommended by the safety standards listed at the beginning. At the end efforts and benefits of code coverage will be compared with pragmatic recommendations for every day usage. https://conf.qtcon.org/assets/qtcon.jpg harri Video Slides: Qt C++ and QML Code Coverage 2016-09-02T17:30:00+02:00 17:30 01:00 B09 b09_-_2016-09-02_17:30_-_lightning_talk_-_585 Creative Commons by SA false OAuth and Qt +++ PostBooks, multi-user accounting/CRM/ERP +++ Synchronizing complex animations in QML +++ Design, dummy! +++ One year of WikiToLearn Misc lightning_talk <b>OAuth and Qt</b> "Brief introduction to OAuth.

The presentation will explain the Migration Protocol, and underline the best practices which can smoothen the process and increase the chances of success. In addition, it will present the business opportunities related to large migrations.

It can also be used to create private and public sector transparency, a more equal society globally and all in all, a brighter future. Social movements are however not best known for their business potential, and this needs to change. I will present some of the best practices and cases anybody can adapt into their initiatives - or get inspired by to take a look at a social business model that allows for more impact, systemic change, a smart network and broader outreach. A social entrepreneur? What the hell is that? Both Open Knowledge Foundation´s Rufus Pollock and Wikipedia´s Jimmy Wales are notable examples of social entrepreneurship, i.e. building sustainable initiatives using business techniques in often very innovative ways to solve one or more social problems and achieving systemic change. This presentation will give you insight into the whys and the hows, and allow you to learn how to be more impactful, whatever your quest through some lively examples. https://conf.qtcon.org/assets/qtcon.jpg Regina Sipos 2016-09-02T14:00:00+02:00 14:00 00:30 A03 a03_-_2016-09-02_14:00_-_free_software_is_now_the_default_choice_for_the_digital_transformation_-_stefan_richter_-_475 Creative Commons by SA false Free software is now the default choice for the digital transformation Let‘s talk business 30min Free software is now the default choice for the digital transformation Netscape went public in 1995. Which caused a “browser war”. When Stefan Richter started his company freiheit.com technologies in 1999, people in large corporations said: “This Linux thing. Nobody will ever use it here”. Steve Ballmer, then CEO of Microsoft called it “communism”. Now even Microsoft does “open source” - as it is still called by the unenlightened. The world kept on changing and today - as we all are sure that the internet won’t go away - everybody knows that companies need software for their digital transformations. Free Software is now the default option in all large digitalization projects and internet companies. Google, Amazon and Facebook - none of them would exist today, without free software. Stefan will give us a glimpse into the large projects he is doing today from his customers-list that reads like the Who’s Who of the German and European businesses and industry. Why are enterprises like METRO interested in free software? What are the current trends and why and how are larger corporations using free software as their default choice? This talk will help business people to create their own argumentation on how and why to “sell” the idea of using free software in projects to upper management, by showing real-life cases from the last 20 years in the business. At the same time, it will show programmers how much power they actually have to guide these decisions. https://conf.qtcon.org/assets/qtcon.jpg Stefan Richter Video 2016-09-02T14:45:00+02:00 14:45 01:00 A03 a03_-_2016-09-02_14:45_-_legal_entities_for_free_software_projects_-_not_applicable_-_simon_phipps_-_matija_suklje_-_michiel_leenaars_-_744 Creative Commons by SA false Let‘s talk business 60min As a FOSS/OSHW project grows, at some stage it often reaches a point where it requires a legal entity for better operation – whether this be to gather donations, pay for development, handle finances, organise events, consolidate rights, better governance or other reasons. So far in Europe the only real option was to set up an NGO yourself or join an entity in the US. But finally three conservancy-like organisations are emerging in Europe and aim to offload this overhead from your projects. Join our panel to learn if and which of these organisations could help your project flourish best, as well as pose any open questions or concerns you may still have. https://conf.qtcon.org/assets/qtcon.jpg Not Applicable Simon Phipps Matija Šuklje Michiel Leenaars Video 2016-09-02T16:15:00+02:00 16:15 00:30 A03 a03_-_2016-09-02_16:15_-_powering_sales_marketing_with_open_source_-_sam_tuke_-_444 Creative Commons by SA false Powering Sales & Marketing with Open Source Let‘s talk business 30min Freedom is in your binaries and your manuals, but what about your marketing? Open Source companies require cutting-edge tools for growth hacking, and a new generation of Open Source apps are ready to serve. Witness a modern marketing stack of interconnected CRM, campaign management, analytics and more, with freedom included. Start selling Open Source, using Open Source. Open Source companies have a dark secret: they're dependent on data-gobbling proprietary platforms for sales (Google Analytics, Salesforce, Mail Chimp, HubSpot...). But powerful Open Source marketing software is thriving under the radar, with integrated replacements available for most popular apps. This talk will reveal the potential of Open Source tools as a complementary marketing stack for generating business. https://conf.qtcon.org/assets/qtcon.jpg Sam Tuke Video 2016-09-02T16:45:00+02:00 16:45 00:30 A03 a03_-_2016-09-02_16:45_-_gpl_enforcement_in_germany_-_miriam_ballhausen_-_440 Creative Commons by SA false GPL Enforcement in Germany Free Software policies and politics 30min The presentation will start out exploring why Germany sees so many GPL enforcement cases. It will then explain the legal claims that can be brought in case of GPL infringement under German copyright law, before closing with a short summary of procedural aspects of enforcing the GPL in German courts. German courts have to deal with a large amount of GPL enforcement cases. The presentation is intended to explain, why and how the GPL is enforceable under German (copyright) law and to summarize how the GPL requirements have to be met according to German courts. https://conf.qtcon.org/assets/qtcon.jpg Miriam Ballhausen Video Slides 2016-09-02T17:30:00+02:00 17:30 01:00 A03 a03_-_2016-09-02_17:30_-_lightning_talk_-_586 Creative Commons by SA false Debug application crashes in the field under Windows +++ Protocol Generator +++ key IPTV/OTT STB project +++ QSqlMigrator +++ Packaging Qt software for Linux with AppImage Misc lightning_talk <b>Debug application crashes in the field under Windows</b> You ever encounter a crash happening at a client of your application and you don't have a clue whats going on? And you cannot reproduce the issue with your installation? Then you are most likely right in this lightning talk. I will talk about source indexing symbol files and about creating a symbol server and looking at loading a crash dump. <b>Protocol Generator</b> How do you handle all the corner cases of the protocols? This is a source of very annoying bugs and security issues. We propose a to generate all protocol decoding and encoding from a single protocol description. This talk is a short summary of our journey and our conclusions. And finally I will give a glimpse into the bright future of standardized protocol descriptions. <b>key IPTV/OTT STB project </b> I manage embedded software development as a part of Restream company an i believe our key IPTV/OTT STB project might be of interest to QtCon attendees as: - we are activelyusing Qt framework - our product has around 5M active daily users - main UI app just went through major re-design The idea is to share some practices and implementation details of how does Qt helps us to create and maintain single IPTV/OTT player app with a rich number of features across 5M+ embedded Linux devices based on more than 5 system-on-chip platforms (from legacy MIPS to capable ARM). <b>QSqlMigrator</b> Managing SQL schemas through all the development phases and ensuring database schemas match the expectations of the current code without a proper schema management is quite a challenge. QSqlMigrator is a library that enables you to write SQL schema migrations in C++ and verify valid database schemas. Combined with some easy to follow policies, it makes schema errors a thing of the past. <b>Packaging Qt software for Linux with AppImage</b> Many Qt based projects are cross-platform, yet it is not easy to provide packages for all Linux distributions. AppImage can solve that by letting application developers package software in a standalone, self-mounting image that bundles everything the application needs to run on various Linux distributions. http://appimage.org/ Among the projects present at QtCon, MuseScore and Peruse are already using it.

There are many tools that help in the process, but you need to know of their existrance and how to use them efficiently. In this presentation I will do an overview of the powerful tools of wireshark, strace, perf and systemtap. Then I will introduce Project Flashlight, an initiative to aggregate results of different debugging and profiling tools and then allow to look for specific events, compare between different program exections and more. All that without getting into pages and pages of log files. In the process we'll do a number of discoveries like: how many sockets does kcalc use? what changes if you run it on a different system? The presentation shows usage of advances debugging techniques with complicated applications. It will demonstrate existing tools and show how we can find out how is the application interacting with the outside world. Project Flashlight is a new initiative to make the advanced debugging easier by aggregating results of different tools and showing patterns developers care about. It will be useful for all developers who debug complex application and want to learn new tools. https://conf.qtcon.org/assets/qtcon.jpg mrybczyn Video 2016-09-02T12:00:00+02:00 12:00 00:30 A04 a04_-_2016-09-02_12:00_-_automated_testing_of_hybrid_applications_-__-_349 Creative Commons by SA false Or: Presenting a hybrid test framework for hybrid applications Testing and Continuous Integration 30min Hybrid applications are an accepted way of reusing web-components in your native applications and Qt provides excellent support for just that. Unfortunately the testing frameworks available does not deliver the same high level of integration leaving automated testing hard to do for hybrid applications. This tales-from-the-trenches talk addresses how we solved that. When the talking automated testing, there are different schools for web applications and for native applications: For web applications it is convenient and well established to use tools like the Selenium suite that allows a script to introspect and manipulate the DOM of a web application directly in a web browser. The test script can “click” buttons, “enter” text and verify the existence and traits of DOM elements. Combined with a back-end introspection, this allows end-to-end testing of a web application. For native Qt applications the established methodology is to build an executable that is linked against the QtTest framework together with a test class that can introspect and manipulate widgets. But! When developing hybrid applications, there are no framework that can take you all the way from an executable using the QtTest and a test class to the DOM in the embedded web part and back to verification in the test class again. That is why we, at Atlassian, made a hybrid framework for testing hybrid applications. Our framework allow a programmer to implement classic QtTest tests using a Selenium like API to test the hybrid part of any application (that implements the accessibility interface) Take-aways: 1: This talk will give the audience a complete walk through of the code used to test the web part of your application from your C++ code using methodologies familiar from the web world. 2: The audience will get a full demonstration of an implementation of a wire protocol server. https://conf.qtcon.org/assets/qtcon.jpg .

At Ableton, we create and distribute builds of Qt and external Qt-based dependencies for Windows and Mac platforms to ensure a consistent base for all Qt development. This talk will outline the motivations for creating binary packages within the organization, the systems the packages need to work with, the process for creating the packages, and the benefits of certain Qt/KF5 features like binary compatibility and modularity. Ableton shipped an updated Push in 2015 which uses Qt/QML for graphics rendering. We are looking at using Qt for future products too and we require a repeatable, versioned process to create the external dependencies we rely on in a convenient way. This includes the ability to set the versions of external dependencies with the versions of our own source, apply patches and create packages which are easily usable by developers, non-developers and CI systems. https://conf.qtcon.org/assets/qtcon.jpg .

The first half of the talk will introduce the essential concepts and tools one has to face when setting up a development environment for Android cross-compilation and for deploying the application on an Android system. In the second half, the focus is on the availability of KF5 libraries and goes into details on what is not possible on Android. As of today, Android is still the most important platform for mobile applications. Under this light, it is a fascinating idea to make applications that are already available on the desktop systems also available on phones and tablets and by this reaching a drastically increased number of users. Qt did a lot of groundwork in this direction. Yet, the first steps in this area might be a little bumpy, since the Android world simply “feels” very different from what you are used on your Linux system. This talk aims to give a fast but accurate introduction into the world of SDKs, NDKs, cross-compilation toolchains, and packaging files. At the end of this talk, a developer shall have an understanding on what is to do to set up an Android cross-compiling environment and how to start developing on their own. Once the basics about how to develop and compile for Android are there, the focus of the talk goes to the libraries and technologies that are available via Qt5 and KF5. In particular, I want to discuss why certain libraries that we love from the desktop world are hard to get on Android to give awareness what the pitfalls are then adapting an application for Android. https://conf.qtcon.org/assets/qtcon.jpg CoLa KDE's Android wiki Video Approaching KF5 on Android 2016-09-02T16:45:00+02:00 16:45 00:10 A04 a04_-_2016-09-02_16:45_-_getting_the_software_on_our_users_hands_-_apol_-_386 Creative Commons by SA false From release to the user Distributing Software and Resources 30min KDE has been distributing software for longtime now, this doesn't mean it every process has been ideal. New technologies and practices appear every day and also new requirements: we want to target different kinds of operating systems like Android and OS X as well as to reach the users in both traditional GNU/Linux distributions and fancier systems like Flatpak. This presentation will look into how it has been done so far and its reasons, and what should we iterate this process to better serve our users. The contents of this talk is subject to the outcome of the Randa Meeting later this year. https://sprints.kde.org/sprint/301 I've talked about the Flatpak (was xdg-app) parts before here: https://twitter.com/AleixPol/status/732594202849218561 http://www.proli.net/2016/02/24/kde-applications-on-xdg-app/ It's especially important to tackle the issue because it's probably desirable to be able to offer software to the users when the distro can't help, but also keep distributions in mind, because they're the ones distributing most Linux software so far. https://conf.qtcon.org/assets/qtcon.jpg apol Video Slides 2016-09-02T11:30:00+02:00 11:30 00:20 A08 a08_-_2016-09-02_11:30_-_fsfe_opening_-_742 Creative Commons by SA false FSFE OPENING Community https://conf.qtcon.org/assets/qtcon.jpg Video 2016-09-02T12:00:00+02:00 12:00 00:30 A08 a08_-_2016-09-02_12:00_-_the_purity_law_for_honest_and_trustworthy_internet_services_-_rafael_laguna_-_581 Creative Commons by SA false The Purity Law for Honest and Trustworthy Internet Services Let‘s talk business 30min 2016 marks the 500th anniversary of the Reinheitsgebot, the ‘German Beer Purity Law’. For half a millennium this Bavarian mandate has ensured the purity and quality of German beer to the continued delight of drinkers all over the world. However, when we examine the developing landscape of digital and online services in 2016 we could only dream of having an equivalent quality standard. At every turn we see technology companies, governments and venture capitalists scrambling to take advantage of our user data. We must ask ourselves; ‘what internet do we want to pass on to our children?’ One that is structured to ensure maximum profit for advertisers, or one that focuses instead on the preservation of quality and purity for the enjoyment and benefit of all users? For this reason we propose a set of Honest Internet Purity Laws to uphold trustworthy and open internet services as a required standard. The principles of open source software don’t just make better technology — they are a blueprint for a better, more open society. https://conf.qtcon.org/assets/qtcon.jpg Rafael Laguna Video 2016-09-02T13:30:00+02:00 13:30 00:30 A08 a08_-_2016-09-02_13:30_-_strategic_use_of_free_software_at_siemens_-_karsten_gerloff_-_449 Creative Commons by SA false Strategic use of Free Software at Siemens Let‘s talk business 30min Siemens is a large engineering company making highly complex products. Often, these products are mission critical for customers, or form crucial bits of civil infrastructure. A large and growing part of their functionality is implemented in software. Free Software components already are important building blocks in many Siemens products. How does Siemens use Free Software, and why? What's the strategic importance of Free Software for the company? And how does Siemens engage with the global community? While Free Software has been widely adopted in the software business world, there is considerably less public discussion about its take-up in the world of "traditional" industry. At the same time, industrial companies are increasingly making use of Free Software, and are becoming more involved in the community. This talk will explore the industry view on Free Software, and will provide valuable insights to people from the community, from other companies, and from the public sector. https://conf.qtcon.org/assets/qtcon.jpg Karsten Gerloff Video Slides 2016-09-02T14:00:00+02:00 14:00 00:30 A08 a08_-_2016-09-02_14:00_-_open_source_as_a_strategic_tool_-_steffen_evers_-_447 Creative Commons by SA false Open Source as a strategic tool Let‘s talk business 30min On one hand, software is becoming the key element for more and more businesses. On the other hand, the price for software has never been lower. In addition, today it is increasingly provisioned through the World Wide Web and cloud computing in the form of services rather than products. The successful establishment of base technologies, platforms and associated business ecosystems therefore plays an increasingly important role in the context of software. Today decisions regarding software both in usage as well as in development are essential for economic success. Open source software and dealing with it has thereby established as an effective tool for the implementation of strategic business goals. https://conf.qtcon.org/assets/qtcon.jpg Steffen Evers Video 2016-09-02T14:45:00+02:00 14:45 00:30 A08 a08_-_2016-09-02_14:45_-_obstacles_for_open_source_in_smes_-_peter_ganten_-_441 Creative Commons by SA false Obstacles for Open Source in SMEs Let‘s talk business 30min Every large enterprise now uses Open Source Software and most have recognized that for maximum benefit and to mitigate risks they need to have a strategy, processes and tools around it. Not so in many small and medium sized enterprises. Here it is sometimes unknown by management if Open Source Software is used at all and many risks are feared - sometimes for good reason. Yet, usage of Open Source Software brings many potentials also to SMEs: Not only does it help to make investments more sustainable and thus increases long-term profitability. It also helps organizations to innovate and enables them to adopt to changes in the market or in technology more easily. So, which are the specific problems which especially medium sized companies have with Open Source Software? How can they use it successfuly? And what can we as the open source community, regulators and vendors of information technology do to make the "German Mittelstand" and SMEs in general more succesful and innovative with Open Source for mutual benefit? The talk might be interesting for Open Source / Free Software activists wanting to understand which specific challenges SMEs have with Open Source Software.

The associated business model is based on the idea of crowdfunding. The customers form a community which finance the solution and develop it together with potentially several companies or individuals. The architecture of the solution makes it possible to preserve individual needs and still benefit from the joint development. In collaboration with the largest children and youth organizations in Switzerland, we built hitobito [0] - a solution for the membership and course management. I would like to explain the idea of ​​community solutions and share our experiences from the projects. Moreover, we are constantly looking for new organizations or developers/companies who share our vision of collaborative software development. In this way, we help establishing free software, particularly in the public administration sector and NGOs.

After realizing global bike sharing information was not publicly available we ended up going after the task of solving the problem for once and for all: a free and open API for others to create applications, visualizations and research on bike sharing data. Fast forward today and thanks to the community, the CityBikes project supports more than 400 cities all around the world and our API powers most bike sharing transportation apps on all platforms. The CityBikes [1] project is a good example of the benefits on the so-called "open data". When data is made available, the community is eager to contribute to and improve public services. We are usually regarded as an "open data project", even though less than 10% of our data feeds come from properly licensed, documented and machine readable feeds. Our project showcases the need of a better policy than the PSI Directive [2] regarding re-use of public sector information, and some common misconceptions between representation and data. The main problem with the PSI Directive is that it does not take into account Public-Private partnerships (PPP). If data ownership or re-use is left out of the deal, the company kidnaps the data and leaves both the city council and its citizens at the mercy of the company providing the service. That is, only the company (or any other company in agreement with the "umbrella company") is to provide applications to use their systems. We as citizens should demand that any project that comes as a result of a public-private partnership should put the data right where it belongs: the public. https://conf.qtcon.org/assets/qtcon.jpg Lluis Esquerda 2016-09-02T14:45:00+02:00 14:45 00:30 A06 a06_-_2016-09-02_14:45_-_how_to_support_activists_using_free_software_-_michal_czyzewski_-_484 Creative Commons by SA false How to support activists using Free Software Community 30min Free, secure infrastructure is crucial to any organization's work, and to NGOs' work especially.

They don't have the resources to protect themselves with expensive solutions and they don't trust most companies. This is why the Czech Technical University started the Stratosphere IPS Project. It is an effort to develop a free software Network Intrusion Prevention System based on advanced Machine Learning algorithms. The goal of the project is to freely protect NGOs and the civil society at large by giving them this advanced defensive tool. The Stratosphere IPS Project provides an off-line free software tool and also a free cloud-based service where NGOs can send they network flows for real time detection. Stratosphere works by modeling the behavioral patterns of known malicious connections from malware and detecting new similar activities by using Markov Chains models. Stratosphere is free software because it is the best way to open our results and because NGOs should trust our work. This talk will show the Stratosphere project, the open model of sharing and how to detect real malware using machine learning in the network. Our topic is a very important one: how the security tools should be free software if we are going to trust them. Most current solutions for using machine learning tools are proprietary because the algorithms are an asset of the company. In this business model, NGOs are left alone without any protection. The CTU University proposed to open its state-of-the-art research in order to protect NGOs with a trustable and advanced free software solution. We believe that NGOs need to work with organizations that are open about their work, about their mistakes and that are willing to show what they are doing. Currently Stratosphere is working with four organizations that are sending their data to us and we are doing our best to protect them continually. https://conf.qtcon.org/assets/qtcon.jpg Sebastian Garcia 2016-09-02T16:15:00+02:00 16:15 00:30 A06 a06_-_2016-09-02_16:15_-_oposso_-_free_subscription_management_-_johannes_loxen_-_477 Creative Commons by SA false OPOSSO - free subscription management Let‘s talk business 30min In early 2015 SerNet started a new free software project called OPOSSO that has been published in May 2016 under AGPLv3. OPOSSO is a subscription management platform that makes it easier for programmers to establish a sustainable subscription based business model. OPOSSO provides automated handling of a high number of subscribers and the start and end of their subscriptions in combination with web shops and software repositories. OPOSSO has been awarded with the "OSBAR" (Open Source Business Award) by OSB-Alliance in 2015. The talk will describe the functions of OPOSSO and how it runs in production at several software projects. OPOSSO can observed in production at https://oposso.samba.plus since September 2015.

QtLocation was initially introduced as part of QtMobility. With Qt5, the various QtMobility components have been progressively incorporated as Qt modules. QtLocation is the latest addition to Qt. Qt 5.6.0 is the first Qt5 release to officially include QtLocation as a Qt module, which was previously available only as a tech preview. This talk will discuss the features of the module, how to use them, as well as how to extend QtLocation via custom plugins. The current limitations will also be presented, together with our current roadmap for planned improvement and solutions to some of them. The first part of the talk will be useful for those who have never used QtLocation, or who have had only cursory experience with it. The second part will be more for those interested in extending QtLocation with own data sources and services, as well as those interested in contributing to QtLocation. https://conf.qtcon.org/assets/qtcon.jpg pa 2016-09-02T16:15:00+02:00 16:15 00:10 B03 b03_-_2016-09-02_16:15_-_qt_on_qnx_-_jmcdonnell_-_388 Creative Commons by SA false Automotive, Mobile and Embedded 60min Upcoming developments in the world of Qt on QNX Review some of the changes that will be available in QNX SDP 7.0 scheduled for release in 2017. https://conf.qtcon.org/assets/qtcon.jpg jmcdonnell Slides 2016-09-02T11:30:00+02:00 11:30 01:00 B04 b04_-_2016-09-02_11:30_-_qt_on_os_x_-_msorvig_-_432 Creative Commons by SA false Workshop on where Qt OS X development is going In depth workshop Qt on OS X . short, medium an long term development plans. https://conf.qtcon.org/assets/qtcon.jpg msorvig 2016-09-02T13:30:00+02:00 13:30 01:00 B04 b04_-_2016-09-02_13:30_-_qt_on_windows_-_not_applicable_-_521 Creative Commons by SA false Workshop on where Qt Windows development is going In depth workshop Qt on Windows, what will be coming. https://conf.qtcon.org/assets/qtcon.jpg Not Applicable Slides 2016-09-02T14:45:00+02:00 14:45 01:00 B04 b04_-_2016-09-02_14:45_-_the_qt_serialbus_module_-_nolden_-_369 Creative Commons by SA false Implementation and use of the Modbus Protocol Automotive, Mobile and Embedded 60min The new Qt serialbus module covers implementation of interfaces with industrial bus systems. One main component is the Modbus protocol (http://www.modbus.org/). The talk covers implementation details and use with Qt/KDE applications. Since Qt 5.6, the serialbus module is introduced with the goal to provide Qt implementations and interfaces to industrial bus systems. Currently, the CAN bus is implemented as a unified abstraction to CAN drivers for Windows and Linux, as well as the Modbus protocol for communicating with industrial devices such as PLCs (programmable logic controllers) that control industrial machines and production chains as well as almost any industrial device containing a higher level of digital logic such as power meters or variable frequency drives. The Qt implementation covers a server and a client interface to serial (RS485/RS232) and TCP networks and implements the Modbus specifications in a most complete way. The talk covers a general overview of history and use of the protocol, the Qt implementation and usage in Qt/KDE applications. A live demonstration of an example application connected to an industrial standard PLC system shows the practical use. Further, an analysis of other industrial network protocols used widely may give an outlook of the implementation of these protocols in the module in future releases. https://conf.qtcon.org/assets/qtcon.jpg nolden 2016-09-02T16:15:00+02:00 16:15 00:10 B04 b04_-_2016-09-02_16:15_-_qtquick_concepts_workarounds_and_best_practices_-__-_360 Creative Commons by SA false QtQuick 60min The intuitive simplicity of QML is blessing and curse at the same time, because Java Script and Property Bindings do not necessarily encourage to write nice and clean source code. In my session, I will talk about the lessons I learned over the last 5 years of professional UI development with Qt. As well as best practices for QML code- and project structure, I will present tricks, workarounds and problem solving strategies for common and frequently asked QML problems, such as: -How do I set up a well organised QML project with outsourced colours, fonts and icons? -How to implement flyouts, overlays or dialogs with a well-thought-out z-layering concept? -How to detect click-events outside a Component (very useful to close an overlay)? -How to develop custom controls in QML that are not only easy to use for the end user but also for the developers? QtQuick is very performant: it runs on pretty much any platform and has a very steep learning curve. This is why Qt currently belongs to the most modern and versatile UI technologies on the market. QML allows to solve many problems with astonishingly little effort. In some cases however, seemingly small problems can result in big questions. In these situations it’s important to really understand the relevant concepts. In my session I want to share my experience by presenting reusable techniques that will save a lot of time. For example: A well organised QML UI project template with outsourced colours, fonts and icons (singleton components / singleton js files). A generic way to handle multiple Z-layers combined with a way to catch click-events outsides the the components own rectangle. Example for handling declarative view interactions using a self-populating menu tree. https://conf.qtcon.org/assets/qtcon.jpg . 2016-09-02T11:30:00+02:00 11:30 01:00 B95 b95_-_2016-09-02_11:30_-_qt_contributor_summit_unconference_-_525 Creative Commons by SA false https://conf.qtcon.org/assets/qtcon.jpg 2016-09-02T13:30:00+02:00 13:30 01:00 B95 b95_-_2016-09-02_13:30_-_qtcore_deep_dive_-_not_applicable_-_522 Creative Commons by SA false Thiago moderates a session on QtCore In depth 60min Thiago moderates a session on the state and future of QtCore https://conf.qtcon.org/assets/qtcon.jpg Not Applicable 2016-09-02T14:45:00+02:00 14:45 01:00 B95 b95_-_2016-09-02_14:45_-_qt_web_-_kkoehne_-_523 Creative Commons by SA false Workshop for developers _of_ Qt with an interest in the QtWeb* modules Web workshop Let's talk about the different QtWeb* modules we have in Qt, most prominently QtWebEngine.

Contrary to what you may have heard, empathy is not something you're innately born with - it's a skill that can be learned, cultivated, refined and taught to others. In this presentation, Leslie Hawthorn will discuss the value of empathy, how you can cultivate it in yourself and your organizational culture, and conclude with concrete steps for leveling up in your interactions with your fellow human beings. https://conf.qtcon.org/assets/qtcon.jpg .lh Video 2016-09-03T17:55:00+02:00 17:55 00:05 C01 c01_-_2016-09-03_17:55_-_venue_closes_-_712 Creative Commons by SA false https://conf.qtcon.org/assets/qtcon.jpg 2016-09-03T11:15:00+02:00 11:15 00:10 B05+B06 b05_b06_-_2016-09-03_11:15_-_the_nxp_smartstudio_use_case_-_alicemirror_-_400 Creative Commons by SA false Qt5.5 + PyQt5.5 complex software integration of a multi-platform application in a mixed environment Qt in Use 60min In this talk, we will show the architecture design strategy adopted to create a desktop application interacting with audio hardware platforms through USB direct connection, Network over USB and Ethernet network. SmartStudio monitosr a wide range of complex DSP real-time data over a user friendly User Interface for the best User Experience, paying special attention to the usability ergonomics of the software. The key factors empowered by the Qt/QML platform are efficiency, reliability, flexibility and real-time data monitoring with a less than 15 ms expected delay response. The starting point was an original, partially working application mostly focused on the Python environment and based on the PyQt4/Qt 4.8. The use of the Qt features through PyQt was extremely limited, resulting in a very slow and uneffective application. During a preliminary step, SmartStudio has been ported to the improved development environment PyQt5/Qt 5.5, and then the internal architecture fully redesigned. The new version was primarily aimed to gaining a significantly improved speed and efficiency, real-time reactivity and flexibility, in addition to an easy-to-maintain and easy-to-use application set of packages. Redesigning the application architecture involved the streamlining and reduction of the Python portion of the application, thus managing only the higher level tasks on a model-view-controller application approach based on the company needs. In this talk, we will analize the architecture design paying special attention to the benefits and advantages of using Qt as a powerful user interface and calculation platform controlled by a Python environment.

Qt is beginning to enable location awareness in mission-critical systems world-wide, with visualization and mapping services and technologies leading the way. The key ingredient to any successful spatial app built with Qt is a strong, rich and intuitive geoservices API, giving the indispensable value of “the geographic context” to Qt applications and the decision-making process. Information that is analyzed in its geographic context provides deeper meaning to the analytical result. There are many well-known patterns, practices and standards-based approaches to bringing location information to the Qt platform and the broadening of it. Many location API contributors follow these important standards, and Esri is one of these. This paper talks about the critical value of geospatial contributions to the platform through the use of Esri’s ArcGIS Services and API platform, including Esri’s opensource geoservices plugin for Qt. There are a number of very good Qt-based geolocation APIs available to developers. This session will give the audience a glimpse at how geospatial capabilities can be realized in Qt applications, using ArcGIS Qt APIs from Esri. It also covers what Esri's Qt APIs look like, how they work, and what can be created with them. https://conf.qtcon.org/assets/qtcon.jpg .

Indeed, the OpenGL code of your Qt application could have been written before the modernization of the OpenGL API to exploit better GPUs. In this talk, we will walk through a technique to help refactor your old OpenGL code in the safest way possible and get it ready for the 21st century. We can find plenty of existing OpenGL code in the wild, some of it is rather old. Unfortunately due to the radical changes in GPU architecture, OpenGL had to adapt as well, with more modern, better suited APIs. In turn, it pushed forward very different designs for rendering code. Because of those technical changes, it can be very challenging to refactor legacy OpenGL code to prepare a port to Modern OpenGL APIs. In particular because such code tends to have close to no automated test coverage. What can we do with all that code? It could be tempting to start from scratch, but there is a clear chance to break the rendering in some subtle ways. In this live coding session, we'll see how we can start from an untested Qt and OpenGL legacy code base, add new features to it, and move it over Modern OpenGL in less than an hour. It will be a good way to discover how refactoring and pin testing techniques can be used even for your purely graphics code. All of that in a suboptimal codebase and while doing the simplest things that will work. This talk will be interesting to any developer having to deal with legacy untested OpenGL code or those wanting to modernise for performance or new features. But, if you are interested in testing techniques for rendering code in general or attended one of the previous GildedRose sessions held at Akademy or Qt Dev Days, there will be nice advice for you as well. https://conf.qtcon.org/assets/qtcon.jpg ervin Video Code 2016-09-03T13:45:00+02:00 13:45 00:10 B07+B08 b07_b08_-_2016-09-03_13:45_-_integrating_opengl_with_qt_quick_2_applications_-_peppe_-_373 Creative Commons by SA false OpenGL and 3D 60min This talk will introduce you to various effective strategies of drawing raw OpenGL content inside a Qt Quick 2 scene. After a brief introduction to how the Qt Quick 2 renderer works, we will see the APIs in Qt 5.6 that allow us to integrate existing OpenGL code and QML. One of the foundation pillars of Qt Quick 2 is its OpenGL-based rendering pipeline. By leveraging the GPU capabilities, we get 60 frames-per-second animated scenes, real time eye candy and special effects, particles, and so on. Moreover, the main programming language is QML, which is extremely popular amongst developers and designers -- it allows them to quickly prototype and build user interfaces. For these reasons, Qt Quick is becoming the de-facto choice on mobile and embedded platforms. However, can we integrate Qt Quick 2 with an existing OpenGL codebase? Would it be possible to reuse old, working, tested OpenGL code and give it a new look and feel by building a Qt Quick interface that uses it? How far can we go with that integration? In this talk, I will show the technologies available in Qt 5.6 that allow deep integration of Qt Quick 2 scenes with custom drawn OpenGL content. We will discuss the possibility of simply providing a Qt Quick overlay for an OpenGL scene. The discussion will then proceed to the creation of custom Qt Quick Items drawn using raw OpenGL commands, which can then be used from QML. Finally, I will illustrate how to manually drive Qt Quick's own rendering if we need to be in complete control of how and when the rendering happens. The audience is expected to have familiarity with basic QtQuick and OpenGL concepts, but no in-depth knowledge of them is required. https://conf.qtcon.org/assets/qtcon.jpg peppe Code samples Video 2016-09-03T15:00:00+02:00 15:00 00:10 B07+B08 b07_b08_-_2016-09-03_15:00_-_writing_custom_qt_quick_components_using_opengl_-_kfunk_-_378 Creative Commons by SA false OpenGL and 3D 60min Qt Quick and QML provide an easy way to rapidly develop customized, reusable components entirely within QML. As these components grow in complexity, performance and maintainability often suffer, a drawback that is especially noticeable on low-powered embedded and mobile devices. In addition, some specialized components simply cannot be implemented by combining existing Qt Quick items in QML. For these cases, Qt Quick provides access to its underlying OpenGL scene graph via a C++ API. Components created this way are more closely aligned to the underlying scene graph architecture allowing improved performance and a cleaner implementation. Qt Quick provides a flexible and easy-to-use framework for developing a wide range of applications from automotive HMIs to interactive desktop applications. Under the hood, it uses an OpenGL scene graph for rendering, allowing advanced effects and fluid animations even on low-powered systems. Complex components written entirely in QML can cause noticeable performance problems especially on these low-powered systems. Qt Quick provides a C++ API to directly access its underlying scene graph for creating optimized components with better encapsulation. These components can then be reused from QML in the same way as the built-in Qt Quick items. The focus of this talk will be describing the steps necessary to create a Qt Quick component using C++ and OpenGL. We will start with a custom component written entirely in QML and point out the performance and maintenance problems with this approach. We will then reimplement this component in C++ and OpenGL, step-by-step, so that by the end you'll know enough to create your own C++ Qt Quick components. Finally we'll compare the resulting component's implementation and performance against the original to see the improvement. I will also briefly mention the QtQuickFrameBufferObject as an alternative and discuss when you would use it instead of the scene graph API. The talk is aimed at developers with minimal OpenGL experience. It will briefly introduce enough of the basic OpenGL concepts to get you started writing a custom Qt Quick item. https://conf.qtcon.org/assets/qtcon.jpg kfunk Video Slide set 2016-09-03T16:30:00+02:00 16:30 01:00 B07+B08 b07_b08_-_2016-09-03_16:30_-_introducing_mapbox_qt_sdk_-_abinader_-_350 Creative Commons by SA false Embedding Mapbox accelerated vector maps in your Qt application Geolocation 60min Mapbox GL Native is a library for embedding interactive, customizable and OpenGL-powered vector maps into native applications on multiple platforms. With the power and flexibility of Qt, enabling its port for Mapbox GL native was fast and easy. We provide two different Qt APIs - QMapboxGL and QQuickMapboxGL. In this talk we'd like to expose the APIs by going through the features doing a live demo on a Raspberry Pi 3 using Yocto. Mapbox GL Native is a recent product released by Mapbox in July, 2015 — a cross-platform framework for responsive maps with focus on mobile. Now developers can have the most detailed maps sourced from ever-updating OpenStreetMap data, as well as the ability to fully control the style and brand to design maps that perfectly match their app. This is all done using our new on-device vector renderer, which uses OpenGL ES 2.0 technology for pixel-perfect map design, from antialiased fonts to polygon blurring, all hardware-accelerated and optimized for mobile devices — and all on the fly. With the power and flexibility of Qt, enabling its port for Mapbox GL Native was fast and easy. We provide two different Qt APIs - QMapboxGL and QQuickMapboxGL - which solve different problems. The former is a low-level implementation that can be used on previous versions of Qt and is easily integrated into pure C++ environments.

FLOSS communities create freely available products in a social process. Communities with a small number of participants typically organise informally. As the community grows, the need for coordination grows as well and at some point formal organisation is required. Where structure and processes emerge, the principles and norms applied typically reflect voluntary participation and meritocratic peer status. The main interest of the community is to attract and retain contributors and to collect contributions. The presentation will review the governance norms applied by the KDE Community and FSFE as the organisations developed, how the constitutions of the communities reflect the convictions and expectations of their contributors, and how the need to evolve governance norms is at the heart of recent conflicts in both communities. https://conf.qtcon.org/assets/qtcon.jpg miroslav Video 2016-09-03T11:45:00+02:00 11:45 00:30 A03 a03_-_2016-09-03_11:45_-_public_administrations_and_foss_-_not_always_an_happy_relationship_-_karel_de_vriendt_-_453 Creative Commons by SA false Public administrations and FOSS - not always an happy relationship Free Software policies and politics 30min Legal and policy issues around the use of open source software in public administrations and around the participation of public servants in open source communities Although a lot of work has been done already, many IT departments in public administrations continue to struggle with these topics.

Unfortunately those misunderstandings are still widely propagated. They often prevent -- or make it harder -- for individuals, companies, governmental and non-governmental organisations to use the full potential of Free Software.

It is a public resource that government organisations can use, study, improve, and share with each other. For citizens, this means transparency, cost efficiency, and the freedom to interact with their government in the way that suits them best. But not all government institutions are taking advantage of Free Software. In consequence, public funds are being wasted, and programs that should be free are being locked away. This also makes life hard for the Free Software-based companies who employ people in Europe, and pay their taxes here. Many procurement officials are still not fully aware of Free Software. Combined with inertia in public sector IT departments, this means that too many public bodies never look beyond their long-standing relations with suppliers of non-free software. The public sector's procurement choices have very real effects on the economy, and play a significant role in determining the sort of firms that thrive in the market. Even with current procurement practices, Free Software already delivers very significant benefits for the European economy. Anecdotal evidence points in the same direction. Many public adminstrations that begin using Free Software see their IT costs drop by 50-90%. Changing the public sector's buying decisions would have a significant influence on the development of a healthy supplier ecosystem for Free Software products and services. With more government institutions as their customers, many such companies could thrive more quickly, and there would be more and better Free Software programs available to the public. With a campaign focused on gathering information on the status quo of expenses, we want to raise awareness for the tremendous waste of tax money in this field. By providing solid information on the costs of the current procurement policies, we want help decision makers in the public sector to do better -- not only for their organisations, but also for the citizens whom they serve. https://conf.qtcon.org/assets/qtcon.jpg Katharina Nocun Video 2016-09-03T16:30:00+02:00 16:30 00:10 A03 a03_-_2016-09-03_16:30_-_continuous_tests_and_distribution_for_qt_applications_on_desktop_and_mobile_-_lasconic_-_374 Creative Commons by SA false Ship your Qt app faster Testing and Continuous Integration 30min "Code once, deploy everywhere" is one of the mantras of Qt. But how can one really accomplish the same ease of distribution and continuous integration as we know with web development? This presentation will show how Qt applications for desktop and mobile can also be continuously tested and distributed by using free or inexpensive tools. The presentation will take the MuseScore desktop software and the MuseScore mobile app as an example. It will show how for every git push, tests are run, and installation packages made available for Windows, MacOS and any Linux distribution as well as on Google Play and the Apple App Store. MuseScore is a free and open source cross platform music notation software hosted on github.com. It is a Qt Widget app with several external dependencies available on Windows, Mac and Linux. MuseScore uses the CMake build system and regressions tests written with QTest and managed by CTest. As a WYSIWYG software, MuseScore also relies on visual tests managed independently. The presentation will show how the MuseScore project uses Travis-CI to build and run the tests for every push but also every pull requests made to the project. It will also show how Travis-CI is used to deliver self contained binaries for Linux (AppImage) on x86_64, x86 and ARM on Bintray.com and also a DMG package for MacOS on a public FTP server. For Windows builds, our use of AppVeyor will be presented. The discussion will introduce the challenges of building automatically a large desktop app in a relatively constrained environment without any UI. MuseScore also provides a mobile app for iOS and Android. The app is in Qt/QML and built with qmake. We will show how a new version of the app is sent to testers for every build and how the app is cross compiled, automatically tested and, deployed on both Google Play and the Apple App Store together with metadata and screenshots translated in several languages. We will discuss the different problems which had to be solved in order to have a fully automated distribution chain. We hope that sharing our experience with other Qt developers will help to generalize continuous tests and distributions among the Qt community and then develop best practices to solve common problems. https://conf.qtcon.org/assets/qtcon.jpg .lasconic Slides Video 2016-09-03T17:00:00+02:00 17:00 00:30 A03 a03_-_2016-09-03_17:00_-_going_all-in_with_qt_on_mobile_-_kbroulik_-_409 Creative Commons by SA false What it's like to serve iOS and Android with Qt alone Automotive, Mobile and Embedded 30min For three years now my company von Affenfels GmbH has been doing mobile apps for iOS and Android exclusively with Qt, leaving native development behind.

Package managers who are able to tap into huge repositories of Free software have, by their very nature of being Free software, a competitive advantage. Liberal licensing makes it easy for users to install and try software packages. From the user point of view, this choice and its presentation can be a bit overwhelming however. Traditional package managers present huge numbers of packages that don't always make sense to the user. Moreover, contribution processes to popular Linux distributions are often too labor-intensive to follow for casual contributors, for some groups, such as artists existing review processes can appear outright unsuitable. The need for a low-barrier system has long been identified, and for a long time, services such as kde-look.org and kde-apps.org have served us quite well. Still, solutions like Apple's Appstore or Google Play offer a well-presented way of installing software. They are the baseline we will be measured against, so we have to improve. The full potential of an integrated solution to software installation has never been realized, however, and this is what we're trying to offer a plan for, outlined in this talk. The presentation is suitable for a non-technical audience, especially for people interested in the topic of software distribution and involvement of non-developing contributors. https://conf.qtcon.org/assets/qtcon.jpg sebas Video talk slides 2016-09-03T11:45:00+02:00 11:45 00:10 A04 a04_-_2016-09-03_11:45_-_peruse_and_the_art_of_comic_book_distribution_-_leinir_-_381 Creative Commons by SA false Content Distribution By Example Distributing Software and Resources 30min Learn how to get content into your applications using the distributed Open Collaboration Services community based content distribution API, and see how it has been done in the wild. Digital content distribution is not a new subject, and has been around in free software since the inception. The large corporations have caught up recently with their app stores, and while there is still arguments to be made that the Linux package managers are powerful, there is a hole in that model where certain things simply don't fit very well. Open Collaboration Services, originally created for the openDesktop.org distribution network, provide us with a way of filling that gap. Many are already aware of the way the desktop environments from KDE give you ways of fetching new wallpapers and theming, but did you know that there are also applications that let you download both new tools and content for you to use? In the Amarok music player, new music services can be downloaded as scripts. In KStars you can fetch new and updated star catalogues. And now, in Peruse, you can download and read comic books. During this presentation you are introduced to the concepts of social digital content distribution as represented by the Open Collaboration Services, and you are shown how it has been done already, presenting best practices and technological options, depending on the particular needs of your application. https://conf.qtcon.org/assets/qtcon.jpg leinir Peruse Website Open Collaboration Services Video Presentation Slides 2016-09-03T13:45:00+02:00 13:45 01:00 A04 a04_-_2016-09-03_13:45_-_have_you_tried_turning_it_off_and_on_again_-_baloneygeek_-_povaddict_-_583 Creative Commons by SA false KDE SysAdmins plans for the future KDE‘s Latest and Greatest 30min KDE's system administrators have a to-do list that is a couple of miles long. At the same time there's a daily churn of server maintenance, ticket servicing, spam killing and a litany of other small tasks that have to be taken care of. Over the last year, however, we've managed to shorten that mile-long todo list, and we're on track to check a lot of tasks off in the next few months. Some of the tasks on that list include modernising our git servers, finally finishing the migration to Phabricator, making Identity easier to manage, making email services and code-hosting redundant, and killing off older unmaintained sites and replacing them with new ones. In this talk, we'll talk about what we've changed so far, what we're planning on doing in the recent future, and most importantly, how KDE contributors' workflows are going to be affected because of the changes. We're also going to talk about where we're currently stuck and could do with a bit of help. Sysadmin is an unique part of KDE, where people with an interest in system administration and DevOps, and a preference to work on languages like Python and PHP find a home in our community.

For this purpose we have a KDE Framework named NetworkManagerQt which wraps everything available on NetworkManager's D-Bus into a library which is much easier to use and provides many convenient features. In this talk I will go through the structure of NetworkManager D-Bus API and show you the basics of using our NetworkManagerQt framework.

BSD Operating Systems are currently not main targets of Qt and KDE though ports are provided by ports maintainers of the main projects (FreeBSD, NetBSD, OpenBSD). The talk covers porting work on the example of the KDE/FreeBSD initiative (https://freebsd.kde.org/) and focuses mainly on questions of improving operating system support for BSD systems, pre-release packaging and testing and avoiding any after-release patching. Shorter release cycles of "upstream" code also require a change of the workflow on the side of packagers to interact with developers to get into the release cycle for providing functional ports at the time of release. https://conf.qtcon.org/assets/qtcon.jpg nolden KDE/FreeBSD Team Video 2016-09-03T16:30:00+02:00 16:30 00:10 A04 a04_-_2016-09-03_16:30_-_the_pity_state_of_linux_desktop_security_-_mgraesslin_-_324 Creative Commons by SA false Platforms and Integration 30min The Linux community is proud about their secure system. It laughs at the competitors, their security problems, the malware for those systems and praises itself for being awesome as there is no malware. But the reality is different. Our desktop is designed around the security of X11 which means it's non-existent. X11 has no security model and many severe security flaws from allowing keyloggers to just take over the complete windowing system. Given the non-existent security on X11, it's normal that applications trust applications running as the same user. This is known as "if it runs, it is trusted!" There is no point trying to protect against malware on the same system, it can just talk to X11. With Wayland we have the chance to create a secure system from a windowing system perspective. The protocol doesn't allow key loggers, doesn't allow grabbing window content, etc. etc. So one would think that Wayland improves the situation. Alas that's not the case. Installing a key logger on Wayland is still trivial, taking over the complete session is still trivial. All the problems of X11 are still there, because the system is not secure. Everything is trusted, everything can modify every aspect of the running or the next running session. Fixing this is difficult, it's an uphill battle against the mentality of "if it runs, it is trusted". In this talk we will look at how bad the security of X11 is and how one can take over a (KWin) Wayland session. We will look at the various efforts in Plasma to fix these problems and to make it more difficult for malware to get into the system. https://conf.qtcon.org/assets/qtcon.jpg mgraesslin Video Slides 2016-09-03T17:00:00+02:00 17:00 00:30 A04 a04_-_2016-09-03_17:00_-_writing_a_qt_application_in_rust_-_vandenoever_-_419 Creative Commons by SA false Platforms and Integration 30min Rust is an exciting new programming language.

Lydia and Thomas will talk about why they think having a vision and mission is important for a Free Software community, and share their experience with overcoming obstacles on the route towards them. Furthermore, they will give insights into how the vision and mission affects KDE's day-to-day activities and what it means for the future. At least year's Akademy, KDE started the journey to create a Vision for the whole community to rally behind and find direction. During the process, we found that creating a Mission Statement to describe how we want to achieve our vision would be equally important, so after we had agreed on our vision, we set out to create a mission statement as well. This talk offers a behind the scenes view of the process, and details some of the obstacles we were confronted with on our way and how we overcame them. Lydia and Thomas also offer some insights into how our vision and mission have affected KDE since their creation, how they have facilitated discussions and streamlined decisions.

This talk presents the motivation, design principles, major features and future roadmap for Minuet. Minuet is the newest member of the KDE Education suite and aims at providing a full-featured platform for music education. Its very first release occurred as part of KDE Applications 16.04 and already provides a set of 44 exercises regarding ear training. Minuet relies on extensive use of MIDI capabilities to provide a flexible and powerful environment for music education. Minuet's core architecture enables the specification of new exercises as a set of simple JSON files, which are automatically merged and processed in order to build the Minuet's UI. For that purpose, we adopt a lot of dynamic QML coding. Current and future work include: the development of a new version devoted to mobile platforms (to be undertaken as a Google Summer of Code 2016 project), support for multiple music instruments, use of singing and claping data (from the computer's microphone) as input devices, and a flexible architecture for defining and applying exams. This talk presents the motivation, design principles, major features and future roadmap for Minuet. I'll talk about how Minuet compares with other proprietary and FLOSS software for music education, its current features and how the community is been structured, as well as the goals we expect to achieve regarding its use in other platforms, integration with social media, and pedagogic aspects. https://conf.qtcon.org/assets/qtcon.jpg sandroandrade Minuet Web Site Video Slides 2016-09-03T15:30:00+02:00 15:30 00:10 A08 a08_-_2016-09-03_15:30_-_open365_using_desktop_applications_as_webs_-_afiestas_-_418 Creative Commons by SA false Bringing linux desktop applications to the Web Web 30min Porting Desktop applications to the Web is usually super costly as it might involve huge refactoring or even complete rewrites. Instead, we propose to bring the application interface to the Web and manage them using containers to keep the cost low. At Open365 we are using curated desktop applications to complement our Web based file cloud. Simply put it would be too costly to develop from scratch PIM and Office apps using web technologies, so instead we looked around and picked the best free desktop applications to do the job. We are using Kontact for PIM (Email, Contacts, Calendars...) and LibreOffice for document editing, everything integrated in our platform that allows us to scale really easily.

With the experience of organizing 7 Randa Meetings I'd like to invite people to listen to this how to and stand right there to answer questions. In 2009 everything began. I decided to organize a developer sprint for the community I used a lot of my software from. Thus the 3rd edition of a Plasma sprint (called Tokamak back then) was held at the Chalet (holiday house) of my family in Randa, Switzerland. I could welcome around 20 developers and contributors form Serbia to Brazil working on my favorite desktop workspace. Back then I was cooking myself for this crowd, showed them area and offered them internet connectivity and electricity to work on code. 7 years later I might need to cook again myself as I'm still searching for a chef but the Meetings grew and we're in a different house in the some village. 40 to 60 people meet year by year in the middle of the Swiss Alps. Undistracted in a beautiful surrounding they can concentrate on coding, discussing and finding solutions for difficult IT problems. But to make these Meetings real I need to spend one to two months per year for preparations, organization, logistics and financial matters. Over the years my family supported me a lot and I found some locale and less-locale helpers outside of KDE that helped me too. So should one start that big or how many people does a KDE sprint need to have to be a real sprint? And what should one look out for if you want to organize such a meet-up yourself? https://conf.qtcon.org/assets/qtcon.jpg unormal Video 2016-09-03T17:00:00+02:00 17:00 00:30 A08 a08_-_2016-09-03_17:00_-_factors_affecting_free_and_open_source_software_foss_adoption_in_nigeria_-_mni_-__-_426 Creative Commons by SA false Community 30min To get a better view of the current FOSS adoption in Nigeria, several factors are going to be discussed, the presentation will explores the penetration of FOSS into Nigeria and how various state and federal governments react to the use of FOSS between 1999 - 2016. The presentation will also discuss some factors affecting the adaption of free and open source software in both academic and corporate institutions in Nigeria and also the ways and strategies in which the factors can be overcome in the country. Significant negative factors like compatibility, lack of resources and time, lack of support, lack of research and development, employment of additional resources, on-going support and training among others contributed to lack of adoption of FOSS in Nigeria. In the context of current limited financial resources and capacities in information technology in the country, Nigeria can examine how to better use the opportunities presented by the emergence of free and open source software (FOSS) to leapfrog into the information age and bridge the digital divide through reduced costs and less dependency on imported commercial software. https://conf.qtcon.org/assets/qtcon.jpg mni . 2016-09-03T11:15:00+02:00 11:15 01:00 A06 a06_-_2016-09-03_11:15_-_high-dpi_qt_-_msorvig_-_433 Creative Commons by SA false In depth workshop Planning future high-DPI work Possible topics: - Fixes and Improvements for QtWidgets - Fixes and Improvements for QtQuick - Fractional scale factor support - Icon/image sets with support for image density - Platform configuration issues https://conf.qtcon.org/assets/qtcon.jpg msorvig Video 2016-09-03T13:45:00+02:00 13:45 01:00 A06 a06_-_2016-09-03_13:45_-_qt_graphics_on_embedded_linux_-_lagocs_-_348 Creative Commons by SA false In depth 60min Let's discuss what's new and what's happening regarding Embedded Linux in Qt 5.6 and later versions, focusing mainly on the eglfs platform. https://conf.qtcon.org/assets/qtcon.jpg lagocs Video 2016-09-03T15:00:00+02:00 15:00 01:00 A06 a06_-_2016-09-03_15:00_-_qt_quick_graphics_state_of_the_union_-_lagocs_-_327 Creative Commons by SA false Qt Quick advancements in Qt 5.8 and beyond QtQuick 60min As announced earlier this year, the Qt graphics stack - and first and foremost, Qt Quick - is undergoing the most significant changes since its introduction in Qt 5.0. The aim of the modularization process is to remove the strong OpenGL dependency, paving the way for other graphics APIs in the future, and to strengthen support for environments where accelerated graphics is not feasible. The previously standalone Qt Quick 2D Renderer is going to become a core part of Qt Quick with a new LGPLv3 license, making it available out of the box on every platform. In addition to a number of internal changes and enhancements, the introduction of partial updates will be visible to every user of this backend since expensive fullscreen updates plaguing earlier releases are now avoided. To prove that the changed Qt Quick Scenegraph interfaces are suitable to handle graphics APIs different from OpenGL, an additional backend using Direct3D 12 is being developed in parallel with the rest of the changes. This also provides the foundations for potential future support for APIs like Vulkan or Metal. While OpenGL remains the default, number one choice, and many Qt Quick applications are expected to be able to run on a different backend without changes, there are cases, typically involving custom QQuickItems or shader effects, that will need attention and potentially a few changes from the applications. The first set of the Qt Quick improvements are expected to get integrated into Qt 5.8, due H2/2016. It is now therefore time to take a look at what these changes mean in practice. https://conf.qtcon.org/assets/qtcon.jpg lagocs Video 2016-09-03T16:30:00+02:00 16:30 01:00 A06 a06_-_2016-09-03_16:30_-_ffmpeg_technical_discussion_-_503 Creative Commons by SA false What will the future of FFmpeg be?

We will discuss how threads, QObjects and events interact together; how a thread affinity of a QObject has a play in signals and slots connections; and how you can leverage the modern C++11 threading capabilities in your Qt application. Cross-platform thread support was introduced in Qt 2.2, released in 2000, ages before it finally got standardized by C++11. This support has allowed developers using Qt to succesfully build countless multithreaded applications, running natively on many operating systems: Windows, Linux, OS X, QNX, iO S, Android, and so on. Across the span of four major versions Qt's threading facilities have been greatly expanded and improved. Following Qt's evolution across the years, a number of "design patterns" have emerged, in order to allow developers to use these facilities to the maximum extent, and not fall into any of the countless traps of multithreaded programming. In this talk I will discuss the basics of thread support in Qt, starting from QThread, the central class in Qt that manages a thread. I will then focus on the interactions between QObjects, QThreads and thread-local event loops, and how all of this plays a role into the cross-thread signals and slots. The most common pitfalls will be analyzed and discussed here. I will then show how to "mix and match" Qt and C++11/14 threading and synchronization primitives, and what degree of support one can expect when moving away from Qt's constructs in favour of the standard C++ ones. https://conf.qtcon.org/assets/qtcon.jpg peppe Video Slides 2016-09-04T13:00:00+02:00 13:00 00:10 B05+B06 b05_b06_-_2016-09-04_13:00_-_the_qt_wayland_compositor_api_-_johanhelsing_-_392 Creative Commons by SA false In depth 60min QtWaylandCompositor allows you to write your own Wayland compositor, making it possible to create custom user interfaces for multi-process embedded applications.

In this talk, Kirigami's maintainer will tell you a bit about its technical background and about how to get started using it for development, while its principal interaction designer will tell you about its underlying fundamental design goals and principles, and how you can get the best user experience out of Kirigami applications. Kirigami UI originally started in 2015 as Plasma Mobile Components, a set of QML components created to facilitate building consistent applications and system features for Plasma Mobile. In the beginning of this year, Marco Martin decided that it could be more than that: A general framework for creating mobile and convergent applications across platforms (it's Qt, after all!). Together with KDE's V Design Group, we set out to build Kirigami out into a whole design philosophy, akin to Google's Material Design, with its own set of components to implement it across platforms and device classes.

A Free Software community or project can be seen as a movement, or as an organization which creates products. From a product-focused perspective, a community or project is not defined by what its members want, but by what it creates, and what benefits that product brings to its users. A product is only worth creating if it brings value to a relevant group of users, and every aspect of it is measured by that criterion. A product-focused project makes sure that it collects actionable feedback from its users and keeps the quality and attractiveness of its product high. From a movement perspective, several project groups together form a movement, which is defined by its overarching goal. The actions of every group are defined and measured by their contribution to that goal. The overarching goal is usually not realistically achievable, but it is what keeps the movement going. It is broken down into multiple, achievable short- and mid-term sub-goals. A movement-focused mindset makes sure that the different groups within a movement work together to achieve their common goal. Both mindsets can bring benefits to a Free Software community: The movement-focused mindset keeps its motivation up and its actions coherent, whereas the product-focused mindset ensures that the product's quality and value to its users is not forgotten. Ideally, it should switch between both, depending on the question at hand. https://conf.qtcon.org/assets/qtcon.jpg colomar Video Presentation 2016-09-04T11:45:00+02:00 11:45 00:30 B07+B08 b07_b08_-_2016-09-04_11:45_-_what_makes_a_web_service_free_as_in_freedom_-_cornelius_-_325 Creative Commons by SA false Web 30min KDE is all about free software. If you run this yourself you enjoy its freedoms, you are in control of your digital life. The situations is different when using software which is run by others as a service. How can we make sure that this is respecting your freedoms a well and that you keep the control over your digital life. This presentation is intended to be the beginning of an answer to this question. KDE provides a lot of free software. If you run this yourself you enjoy all the benefits of free software, the freedoms to use, study, share, and improve the software. You are in control of your digital life. The situation is different when using software which is run by others as a service, even if these others run free software. There you don't have control about what software is run and how. What does that mean for your freedoms? How much control do you still have? Do you know what is happening to your data? Do you have the freedom to switch to a different service? How is your own freedom affecting the freedom of other users of the same service? There are a lot of questions like these. There are a couple of approaches how to address these questions. There are the user data manifesto [1], the "Terms of Service; Didn't Read" site [2], the GNU ethical repository criteria [3], and other attempts at covering specific aspects of freedom of web services. But there is no definition yet what makes a web service free as in freedom, which is as concise and elegant as the free software definition is. This presentation will give an overview of where we are, what approaches to defining the freedom of web services exist, and what is missing. It's intended to start a discussion which leads to a definition of what a web service has to provide to give users the same freedom as they have when running free software themselves. This is the beginning of a journey and everybody who cares about freedom is invited to join.

We released the first Qt5-based version, restructured our code base and set ourselves more ambitious goals. Let's look a bit deeper into some of the important changes that have happened in KDE PIM in the past year, and peak a little into the future. In this talk we will go over some of the most important changes that happened in KDE PIM in the past year. This includes discontinuing support for some components, switching over to a binary protocol, splitting of repositories and more. We will also look a bit into the future, talk about the current work in progress as well as our middle and long-term goals and tasks.

We will discuss what we have achieved to date, how it can be used by the KDE community and our software users and our plans for the future. KDE neon is brining a revolution to the way KDE delivers its software on Linux. A KDE project providing KDE software directly to our users cuts the feedback loop and allows us complete control of the experience. Using the latest buzzword compliant devops techniques with containerised continuous integration and continuous deployment, cloud provisioning and orchestration with an active engagement through social media presence, KDE neon is updating the model of how KDE provides its software. We will show how KDE neon is used by Plasma developers to test their latest software and their releases. We'll show how people interested in trying KDE's software finally have an answer to the questions of where to get up to date versions. And you can finally find an answer to the question, KDE neon: terrible idea, or simply a huge mistake? https://conf.qtcon.org/assets/qtcon.jpg Riddell Video KDE Neon Akademy 2016-09-04T14:15:00+02:00 14:15 01:00 B07+B08 b07_b08_-_2016-09-04_14:15_-_do_good_things_and_talk_about_it_-_pr_for_oss_projects_-_mfeilner_-_496 Creative Commons by SA false Lessons learned in 20 years of Open Source PR Community 30min This talk will tell, teach and train open source community members, company leaders, developers and open source project leads how to deal with the press.

It is not feasible to write (de)serialization code for all formats in each language. It is better to generate code from a description of the file format. Most computer programs read and write files. Usually, the translation from bytes in the file to information in the program is coded by hand. For live communications between programs the situation is better. On the desktop, DBus is most well known example of a protocol with automatic (de)serialization. And for XML files there is XMl Schema and Relax NG. Yet, there is no widely used method for generating code for reading arbitrary binary files and text files. MSOScheme is a library that translates a description of binary Microsoft Office files into C++ and Java code. It is used in Calligra to translate these files into OpenDocument Format. Binary Microsoft Office files are extremely complex, but using the generated code is easy and safe. The Data Format Description Language (DFDL) is an open specification to describe file formats. New data formats are created every day and new programming languages come into being quickly. It is not feasible to write (de)serialization code for all formats in each language.

Then throw it all out and start again. Attendees of this talk will learn about making iterative design changes to applications, the importance of reviewing designs, ideal places to focus, and pitfalls. We will also examine the signs a design is near retirement and steps to prepare for bigger change. Additionally we will learn about hypothetical user 'personas', how they impact the decision-making process, and the importance of referring to them for design changes.

However, a large part of today's computer-aided research is performed with non-free software. In academia there is an additional dimension to the usage of non-free software aside from the issues commonly associated with it. Traditional academic norms include the concept of communality — i.e. sharing so that others may build upon your findings — which in most interpretations implies free software. However, situating software in academia in the broader context of present academic cultures reveals considerable drift from these traditional academic norms. This talk examines reasons for the prevalence of non-free software in research and highlights differences between some disciplines. Particular focus lies on strategies to be adapted from those disciplines that favour free software. A free software working group at a local university serve as case study of how free software may be practically established in public institutions. This talk does not deal with arbitrary software used in academic institutions but only with software which is involved in the actual act of research. It does not discuss technical attributes of any piece of software but tries to uncover the mechanisms of software usage and software production in academic research. By doing so it presents the underlying political and ethical issue in academia, nowadays discussed under the label open research: Is it necessary to release the software used for research in order to be a good researcher? If so, is this only necessary so others can reproduce your results or is there a moral implication to release this software under a free license so others can reuse and adapt it? In this talk I would like to show some steps how to establish free software in academic institution, pitfalls to look out for and arguments to be ready to counter. Most of these insights I take from personal experience in a number of academic fields which are very diverse regarding the attitude towards free software. However, there are many aspects readily applicable not only to academia but also to other types of institution. I will also discuss likely future actions of distributors of non-free software which target academic institutions and how to be ready for them. By studying actions that we took in the local working group and their results one might see that some high-impact goals can be fairly easy to reach. This is greatly helped by a general willingness to be "open" in academia, as reflected in the open research movement or the open access movement. However, there are some actors involved in academia who are only interested in the positive image connected with the "open" label. In this talk, I will try to present some aspects of this "openwashing" and how it relates to free software. https://conf.qtcon.org/assets/qtcon.jpg Tobias Schrank Video 2016-09-04T10:30:00+02:00 10:30 00:30 A03 a03_-_2016-09-04_10:30_-_the_future_of_search_maybe_not_web_search_-_michal_christen_-_740 Creative Commons by SA false The Future of Search: Maybe Not Web Search? Beyond Code 30min In the last twenty years there had been many different kinds of search engines and web search is just one of them. The talk will show how information is organized with search engines and emphasize the need for search engines by the people for the people with free software. Description: It appears that all large services have distributed but centralized architecture. Sometimes these services are called cloud services. Even web search - as i.e. google provides - is a cloud service. There is free software to do web search, but not on a large scale. Most of the real-time information is not any more available in the web, but in special services like Twitter, Instagram, YouTube etc. When we think of search engines of the future we must consider such kind of information sources as well. The talk shows which tools could be used to create search engines to harvest and index such sources to create search engines for the future. https://conf.qtcon.org/assets/qtcon.jpg Michal Christen Video 2016-09-04T11:15:00+02:00 11:15 00:30 A03 a03_-_2016-09-04_11:15_-_software_heritage_-_the_universal_archive_of_free_software_-_roberto_di_cosmo_-_466 Creative Commons by SA false Software Heritage - the Universal Archive of Free Software Beyond Code 30min Software Heritage is a major undertaking for collecting, organising, preserving on the long term and sharing all free software source code, that has been started at Inria one year ago and is now opening up for global participation. It has potential impact on a broad set of fields and will be of interest to a wide audience. The Software Heritage initiative is building the universal archive of the source code of all the software publicly available. Our main goal is to ensure long term preservation of and broad accessibility of the technological and scientific knowledge of mankind that is now embedded in the many free software components that are pervasives in all aspects of our modern societies. Many applications can be built on top of this fundamental infrastructure, ranging from cultural studies to teaching material, from scientific applications to industrial tools.

Where are women in Open Source? Why the gap is so big? Women participation in open technology and culture is very important so we should all pay more attention. This talk will be focused on the large steps we can take to reduce this gap. Also i'll share my experience at our hackerspace in Tirana (Albania) since we have lots of womens there. My presentation will highlight different aspect of diversity and how fedora is supporting diversity in all terms. It is wonderful to be a women and women should have equal rights to man - be it social, political, economic, or cultural. But, If we look at the percentage of women participation in any field, be it tech or any other field, ratio is damn poor. We, being in the eligible category to guide other women to open source culture, should take steps forward to make this ratio better. I know, taking an initiative in this man dominant area is not easy. But together, we can and we will make the difference. Every tiny little step counts, like educating poor female children, reaching out to college girls to spread knowledge and opportunities about open source, educating them about Ada Initiative, the GNOME Project’s Outreach Program for Women, OpenHatch, Women in Drupal and other similar projects. There are so many nice outreach programs for women in open source, we just need to spread the knowledge and motivate every women out there to join the movement. There are lots of things to do, not just coding and developing, everybody can find other exciting things to do in open source projects i.e. writing, documentation, designing, translation, testing etc. Every established women in open source should feel "obligated" to educate/ help/ motivate at least two other women in her life span to join open source community and make this open source culture more lovable and beautiful and little more feminist. https://conf.qtcon.org/assets/qtcon.jpg Jona Azizaj Video slides 2016-09-04T13:00:00+02:00 13:00 01:00 A03 a03_-_2016-09-04_13:00_-_show_europe_-_746 Creative Commons by SA false To promote national Free Software organizations in Europe Community 60min The FSFE hosts a European session to give various (national) organizations that are actively working for Free Software inside Europe the chance to present themselves.

Qt ships with a lot of 3rd party code, not under CLA. This means the code cannot be relicensed, making it difficult to comply. Furthermore, not closely following any update changes might result in security issues. Let's discuss how to improve the situation, e.g. by a more structured approach similar to Chromium: - 3rd party code must always be in a '3rdparty' folder - 3rd party code must always be included with a 'README.qt' file with details about the use of the code, where it's hosted upstream etc - Documentation of 3rd party code is directly generated out of these files. Furthermore we might discuss which 3rd party code we can get rid of at all, whether we can directly include upstream git repositories, use tools and standards like SPDX, provide a tool to scan for 3rd party code in custom builds ... https://conf.qtcon.org/assets/qtcon.jpg kkoehne 2016-09-04T14:15:00+02:00 14:15 01:00 A04 a04_-_2016-09-04_14:15_-_making_qml_optional_-_aknight_-_428 Creative Commons by SA false QtQuick bof Working with Uwe Rathmann (of Qwt fame), Andrew has been investigating different techniques for reducing the "QML Dependency" which comes with working on Qt Quick applications.

In previous versions of QtQuick, we had a few Items specialized for handling pointing device events, such as MouseArea, Flickable, PinchArea, and MultiPointTouchArea. Some of them are limited to handling mouse events, so when you use a touchscreen, they rely on receiving synthesized mouse events. This precludes touch interaction with multiple Items, because of the assumption that there is only one mouse - despite the fact that you are using a multi-touch screen. At the 2015 Qt Contributors' Summit, we discussed a potential solution to the problem, from which the present implementation has evolved. The solution is to have one type of event (a synthetic wrapper in Qt 5, and a common base class in Qt 6) for all pointing-device events, and a new larger set of lightweight Handler objects, focused purely on handling events. They can be device-agnostic, or can filter events from specific kinds of devices. They are not Items themselves, but pointer-handling aspects of Items. This talk will be an exploration of these Handlers and their use cases: how to achieve fluid, multiple-touch, multiple-user UIs in Qt Quick. https://conf.qtcon.org/assets/qtcon.jpg ecloud Video 2016-09-04T11:15:00+02:00 11:15 01:00 A08 a08_-_2016-09-04_11:15_-_new_configuration_system_in_qt_5_8_-_lars_-_765 Creative Commons by SA false In depth 60min I would like to give an intro to the new configuration system I’ve been developing for Qt Lite.

The session will give an introduction to fuzzing, the tool american fuzzy lop and the compiler feature Address Sanitizer. Code written in C and C++ is often riddled with bugs in the memory management. Out of bounds accesses, use after free errors and other issues can hamper the security and stability of applications. Unfortunately many free software developers don't use freely available tools that easily allow finding and eliminating many of these bugs. The talk will encourage developers to change that and integrate these tools into their development process. https://conf.qtcon.org/assets/qtcon.jpg Hanno Böck Video Slides 2016-09-04T14:15:00+02:00 14:15 01:00 A08 a08_-_2016-09-04_14:15_-_ui_development_a_tale_of_two_peoples_designers_and_developers_-__-_359 Creative Commons by SA false QtQuick 60min A passion to implement design specifications to each and every pixel is not common amongst developers. Precisely because classic software developers are more eager on developing complex algorithms, optimizing databases and other exiting topics. In contrast, implementing a user interface seems a trivial and boring task – sometimes even demeaning! In most cases, the right questions at the right time decide over success or failure of a project. My session will give insights into proved and tested processes for successful UI projects. Additionally, I promote a better understanding of the need for very close collaboration between developers and designers. The goal is to encourage the developers to discuss questions with designers instead of simply implementing the next best solution. A button here, a label there and the UI is done. Drag and drop editors make it possible. The result proves to be the opposite in almost every case, however. Ever since the emergence of QML, Qt meets the requirements for developing pixel perfect custom UIs with ease. It is not only a question of programming skills, though. To collaborate efficiently, designers and developers need to speak the same language. Otherwise it is almost impossible to implement a UI true to the vision the designer created. In my session, I want to reduce reservations between the two “peoples” designers and developers and encourage the mutual understanding. In most cases, the right questions at the right time decide over success or failure of a project. I will show examples of common misunderstandings and explain how to guide a UI project with the right handover materials to success. https://conf.qtcon.org/assets/qtcon.jpg .

The talk will give an introduction and some hands-on examples about what you can do with it. State Chart XML (SCXML) is a common format to specify state machines. It has been standardized by the W3C and there are many applications that produce or process it. State charts provide a graphical way of modeling how a system reacts to stimuli. This is done by defining the possible states that the system can be in, and how the system can move from one state to another. State charts offer a very concise representation of business logic, and limit the potential for unexpected behavior. Qt 5.7 comes with a technical preview of Qt SCXML, a module to integrate state charts specified in SCXML into your application, and execute them in accordance to the W3C specification. This way a Qt application can be driven from a state chart, rather than from business logic expressed in C++ or QML. With Qt SCXML, SCXML documents can be compiled into C++, which can then be readily integrated into any Qt application. Alternately, SCXML documents can also be dynamically loaded and interpreted at run time. In both cases, states are exposed via Qt properties, so that QML properties can effortlessly be bound to them. It is thus very easy to attach a Qt Quick UI to an existing, or newly written, state machine. The talk will show the full workflow of creating a state machine in a visual design tool, integrating it into a project with Qt Creator, adding a custom data model, and attaching a user interface to it, using QML and Qt Quick. https://conf.qtcon.org/assets/qtcon.jpg ulf Video slides 2016-09-04T13:00:00+02:00 13:00 01:00 B03 b03_-_2016-09-04_13:00_-_deprecating_qt_apis_and_modules_in_the_future_-_lars_-_531 Creative Commons by SA false Qt Contributor Summit Unconference workshop https://conf.qtcon.org/assets/qtcon.jpg lars Video 2016-09-04T14:15:00+02:00 14:15 01:00 B03 b03_-_2016-09-04_14:15_-_quips_for_qt_-_louai_-_532 Creative Commons by SA false Qt Contributor Summit Unconference workshop Should we have a similiar system as Python has in PEPs? https://conf.qtcon.org/assets/qtcon.jpg louai 2016-09-04T10:00:00+02:00 10:00 00:30 B04 b04_-_2016-09-04_10:00_-_fsfe_wiki_caretakers_-_johannes_zarl-zierl_-_760 Creative Commons by SA false Community 30min Like many wikis, the FSFE community wiki tends to be rather disorganized at times.

Its main components are a matrix of 20 LEDs and a small microcontroller board to generate pre-programmed animations. Attatching a BeagleBoneBlack with WLAN stick also allows concurrent web- or app-based color changing, which is especially great for distracting children while advocating free software to their parents. The complete setup has been designed to allow construction, implementation, programming and usage entirely with free software.

However, multinational companies ask for their users’ data and contributions to advance their own business interests, to improve their products or to enhance their services. However, they regard their users’ contribution as their property without any obligation to share these contributions under an open license. Android, the world’s leading mobile operating system, is Free Software; however, Google integrates its own non-free features so deeply into Android that ordinary users cannot use Android as Free Software and they are tied up with Google, using Google services and thus contributing with their data to enhance Google’s business interest. There are different world views and anthropological and socio-economic concepts behind the idea of sharing. Augustine of Hippo makes sharing a virtue: „Omnis enim res, quae dando non deficit, dum habetur et non datur, nondum habetur, quomodo habenda est”, („For if a thing is not diminished by being shared with others, it is not rightly owned if it is only owned and not shared”) which is also the FSFE’s motto. According to Augustine, man – by the grace of God - is capable of doing good and contribute to the well-being of society. A similar anthropology is also found within Pietism and Puritanism, according to the American Sociologist Robert Merton, „communalism” - a concept favoring communal ownership and the common good – being a basis for the scientific progress as scientific discoveries are shared and not kept exclusively to oneself. In the history of ideas, this mindset resembles the principles of Open Access and Open Data. Open Source Software or Free Software can also be based on the same principles, following the underlying anthropological concepts. In contrast, Thomas Hobbes’s assumption – as laid out in the claim „homo homini lupus” („man is wolf to man.”) - assumes that egotism is a driving force, „bellum omnium contra omnes” („the war of all against all”) is a constant in human society. Adam Smith – in „The Wealth of Nations” makes man’s self-interest the basis for his socio-economic concept: „By pursuing his own interest he [=man] frequently promotes that of the society more effectually than when he really intends to promote it. I have never known much good done by those who affected to trade for the public good. It is an affectation, indeed, not very common among merchants, and very few words need be employed in dissuading them from it.” While everybody is pursuing their own interest, an „invisible hand” - so Smith’s assumption - leads all self-driven interests to ultimately promoting the common good, thus making Liberalism (and Capitalism) the best economic models for society. If egotism is the driving anthropological force and Capitalism is the socio-economic model for society, then hiding code from others, accumulating data and keeping databases locked up, producing software whose data cannot be exported, is the logical consequence. Google, Facebook, Microsoft are symbols of this concept, advancing the company’s profits with their users’ contributions. On the other hand, if sharing is understood in the way of communalism, Free Software – and Open Access, and Open Data, can be the foundation of a socio-economic model for the Information Society that correlates with Augustine’s anthropology. https://conf.qtcon.org/assets/qtcon.jpg Ralf Peter Reimann Video 2016-09-04T10:30:00+02:00 10:30 00:30 B95 b95_-_2016-09-04_10:30_-_design_in_free_open_source_projects_-_experiences_as_a_design_contributor_-_elio_qoshi_-_491 Creative Commons by SA false Design in Free Open Source Projects - Experiences as a design contributor Let‘s talk software 30min Design, community, collaboration https://conf.qtcon.org/assets/qtcon.jpg Elio Qoshi Video 2016-09-04T11:15:00+02:00 11:15 00:30 B95 b95_-_2016-09-04_11:15_-_zerocat_chipflasher_-_open_hardware_diy_with_the_parallax_propeller_-_kai_mertens_-_736 Creative Commons by SA false FSFE community session Community 30min The zerocat chipflasher intends to be a true open hardware chip programming tool, all sources released under a free license, even down to the internal chip design files.

Nowadays, there is a bunch of affordable chipflashers available, but none of them is true open design.In projects, where user freedom is the first criterion for quality, this is a severe drawback. For that reason, the zerocat chipflasher would perfectly fit into the coreboot and libreboot philosophy, offering an alternative means for flashing supported machines like the thinkpad x200/x200s.

Beyond Code 30min No free software user is an island. This has been true always, but never has this been truer than lately. With the advent of social walled gardens, positioning themselves as public infrastructure used by more and more other services, the network effect is stronger an enemy than ever. It cannot be ignored, but can it be defeated? Or, perhaps, co-opted? The Four Freedoms, while being the cornerstone of the free software movement, only deal with software and ignore the question of data. This is understandable: when they have been created, data almost always resided under users' control, and the real problem was making sure users have the necessary, freedom-preserving tools to work with it. Today, we use free software tools to deal with data that effectively falls outside of our control. Often we cannot access the data directly, export it, import it somewhere else. Garden walls do not have windows, or very small ones only. Even free software itself is more and more often being developed using walled gardens -- GitHub being one example. And, more and more free software is being used to build walled gardens themselves. As is often the case, there is no easy solution. But there are things we as the free software community can do, within the community itself, and as part of our policy work, to push things in the right direction. This requires added focus on some of the values that seem to have taken the back seat in the free software world: compatibility and interoperability. We need to put "social" back into libre social networks, among others. It is time free software tools became compatible with each other. Good news is, some work is already being done. https://conf.qtcon.org/assets/qtcon.jpg Michal Wozniak Video 2016-09-04T13:00:00+02:00 13:00 01:00 B95 b95_-_2016-09-04_13:00_-_videolan_unconference_-_767 Creative Commons by SA false Unconference slot to be defined on-site Community meeting https://conf.qtcon.org/assets/qtcon.jpg 2016-09-04T14:15:00+02:00 14:15 00:30 B95 b95_-_2016-09-04_14:15_-_wikidata_and_your_application_make_your_software_part_of_the_free_knowledge_ecosystem_-_nightrose_-_jens_ohlig_-_492 Creative Commons by SA false Wikidata and your application: Make your software part of the Free Knowledge ecosystem Beyond Code Wikidata is a free and open knowledge base that can be read and edited by both humans and machines.

You’ll learn about the community behind Wikidata and a bit about the legal and license questions around the repository of structured data for Free Knowledge. While Wikidata is used in Wikimedia projects today, we want to emphasize its value for applications outside the Wikiverse. Do you want to display information on notable sights or buildings around? Do you want to build a timeline of events? Wikidata can be your source of machine-readable data for the sum of all human knowledge.

In the meantime, the importance of software has grown beyond the scope of user rights. There are other, public interests in having source code available. The three most pressing reasons in addition to user freedoms are: Source code availability as an accountability mechanism that potentially substitutes strict liabilities Source code availability for purposes of government accountability in a democratic society Source code availability for purposes of data protection to prevent discrimination This is a potentially slightly political topic with a somewhat longer term perspective than the most pressing issues of today. That said, there is an advocacy element to it as well, I do not believe that most of the user freedoms arguments do resonate that strongly with (organisation) users of software since they do not always recognise the extent to which computer software touches the core of their functions and what source availability means for that, especially in the public sector. I have held a version of this talk before, at the LLW workshop in Barcelona in April 2016 and this would be more geared towards developers than to lawyers.
