Am I a Good Programmer?

Nov 28, 10:30-11:10

Abstract: It's something we all ask ourselves: Am I a Good Programmer? But how can we truly know if we're good at software development or not? Evaluating programming skills is notoriously difficult. I'll walk you through some thoughts that might help.

Speaker: Kate Gregory is an enthusiastic C++ programmer and teacher, and has been paid to program since 1979. She believes that software should make our lives easier. That includes making the lives of developers easier! She'll stay up late arguing about deterministic destruction or how modern C++ is not the C++ you remember. She is one of the three leads of the Carbon Language project, a founder of #include <C++>, and on the board of C++ Toronto, which runs CppNorth.

Kate runs a small consulting firm in rural Ontario and provides mentoring and management consultant services, as well as writing code every week. She has spoken all over the world, written over a dozen books, and helped thousands of developers to be better at what they do. Kate is a Visual C++ MVP, and develops courses for Pluralsight, primarily on C++.

Konecranes: Qt Interface Framework Lifts Tons of Work

Nov 28, 11:30-11:45

Abstract: We were talking about containers way before Docker existed, we have modularity and reusability in our DNA. When developing a complex application like a user interface, we believe in decoupling graphics, logic, and communication. Many times communication layer does not depend at all on your team and maybe unknown for a long time during a project. Interface framework handles this and more, allowing to define an abstract data interface to use in the GUI and effortlessly create one or more real protocol backends later. In this presentation we want to share with you the architecture we have set up for our Cabin panel system, leveraging on Qt Interface framework for the data layer.

 

About the Speaker: Master's degree in Computer engineering in 2008. Living in Genoa, in the northern part of Italy. Joined Fantuzzi group research center in Genoa in 2008 as Graphical Interface developer, the company got later acquired by Terex and then by Konecranes. I've so managed to work for three companies without changing my desk. During these years I have worked in the development of a RAD tool for graphical user interface creation as well as participating in many graphical interfaces projects for off-highway, road, and maritime vehicles. Since 2020 leading Konecranes GUI tech HUB in Genoa Engineering Center.

Change? I Was Afraid of That.

Nov 28, 14:15-14:45

Abstract: It has been said that humans are allergic to change. It has also been said that change is the only constant. While some may rush towards change, others seek out islands of stability. Even though technology has a reputation for being about and bringing about change, in our habits, our codebases, and our technical choices we often avoid change. "No need to upgrade to a more recent version of the library." "C++20? We're still thinking about migrating to C++11..." "If it ain't broke, don't fix it!" In this talk, we'll look at the long-term implications of avoiding change in our code and technologies, from skills to security, from legacy to refactoring. Sometimes change for its own sake is a good thing. We need to develop a better relationship with change... a closer and more intimate relationship... we need to embrace it.

About the Speaker: Kevlin Henney is an independent consultant, speaker, writer, and trainer. His software interests lie in programming, practice, and people. He has been a columnist for a number of magazines and sites, has contributed to both open- and closed-source software (sometimes unintentionally), and has been on far too many committees (it has been said that "a committee is a cul-de-sac down which ideas are lured and then quietly strangled"). He has co-authored two volumes in the Pattern-Oriented Software Architecture series and edited and contributed to multiple books in the 97 Things series.

Getting Qt to run on new MCU environments

Nov 29, 09:00-09:45

Abstract: Unlike desktop application environments that provide (more or less) stable APIs on how to render your user interfaces to the screen, getting even a simple UI to show on a new microcontroller or a new real-time OS can be a challenge. Join us for a presentation where we will, in real-time, make Qt run on Zephyr RTOS. We will start with creating a new Qt kit, write basic memory allocation and timekeeping, and finally display rendering functions. After the end of the presentation, you will have a basic knowledge of how to make your MCU environment run Qt

Porting a Large Scale Non-Qt Legacy CAD Application to Qt/QML: The Good, The Bad, and The Ugly

Nov 29, 11:15-12:00

Abstract: Over the last 3 years, we have been working on porting our large legacy CAD software (Alias) to using Qt/QML for UI. We had been using an in-house developed UI framework for the last 30+ years and it was time to upgrade to something more modern to empower our designers and take pressure off of our developers to make them more productive with easier and more intuitive tools. Because of the state of our application, we have taken an all-in approach where we disabled the UI for our CAD software and began building everything bit by bit. During this project, we not only refactored and changed the technology we use for our UI but also the way we work within our team across disciplines.

About the Speaker: Furkan Uzumcu is a senior software engineer at Autodesk. He has worked with many languages and backend, and end frontend systems to solve problems. He's passionate about good UX, software architecture, and design. He's worked with Qt/QML for over 8 years, and developed software for desktop and mobile devices.

Script Automation: Recording User Actions

Nov 29, 13:00-13:45

Abstract: QML is a versatile and powerful component of all Qt applications, beyond the already established use case of building advanced UIs. It can be easily used for in-application scripting [1], leveraging the C++/QML integration in Qt. This has been used internally in our migration helper tool, but beyond just script automation one of the features we wanted was a way for the user to record a script based on the actions he was doing, so he can save it and replay it later. The underlying idea is close to what the text editing macros in Qt Creator can do, with the difference that the output is a script that can be easily edited or amended after recording. In this session, I will show how such a system can be added to an existing application in the least intrusive way possible, how to make it generic enough for handling almost any kind of API, what are the prerequisites for such a system, and how to handle some corner cases.

About the Speaker: Nicolas Arnaud-Cormos has been working with Qt for more than half of his life already, on multiple Qt widgets or QML projects, with a particular emphasis on API design and software architecture. He is a senior software engineer and trainer at KDAB since 2007, and a runner enthusiast in his free time.

Advances in Lower Level 2D/3D Graphics Enablers in Qt 6.6 and Beyond

Nov 29, 13:50-14:35

Abstract: The first six minor releases in the Qt 6 series (6.0 - 6.5) prove that the 3D graphics API and shading language abstraction layers introduced with Qt 6.0 provide a solid, well-performing, cross-platform foundation for Qt Quick, Qt Quick 3D, and in some cases, Widgets even. The story is not complete yet, however. The QRhi API itself is still private today, and using these facilities in Qt applications involves digging deep into Qt internals. In this talk we are going to take a look at how this is expected to change in the subsequent few Qt 6 releases (6.6, 6.7, 6.8): Is the QRhi API going to be opened up for application use as well? Will there be a QRhiWidget and a QRhiItem? How about adding augmenting a Qt Quick 3D with custom draw calls or compute shaders? And more.

About the Speaker: Laszlo is a principal software engineer at The Qt Company in Norway. He is usually working on various parts of the cross-platform Qt graphics stack, focusing mainly on accelerated 2D/3D graphics for Qt Quick and Qt Quick 3D.

Integrating Qt Interface Framework with Qt Design Studio

Nov 29, 09:50-10:20

Abstract: Qt Interface Framework is a powerful tool that allows for the separation of frontend and backend implementations. On the other hand, Qt Design Studio is an excellent tool for designers to bring their designs to life. By integrating the Qt Interface Framework into the designers' workflow, you can ensure that they have access to proper backend simulation, offload developers from UI integration work and ensure both parties can work seamlessly on design and implementation, resulting in a faster and more streamlined development process.

Inter-Process Communication

Nov 29, 10:25-11:10

Abstract: The technique of combining different applications is often useful to achieve faster time-to-market and improved resiliency by breaking down the responsibilities of each component into specialized tasks. Applications, therefore, communicate with those different components (or provide components to others) by way of Inter-Process Communication. Qt provides a number of classes and entire modules to help developers achieve this, from simple sharing of byte data to high-level Remote Procedure Calling. This talk will describe the advantages and disadvantages of the methods and Qt classes, then it will delve deeper into the low-level IPC classes in QtCore, exploring their uses, limitations, and how to best make use of them.

About the Speaker: Thiago Macieira holds a double degree in Engineering and an MBA. He has been involved in Open Source projects for nearly 25 years, with Qt and KDE since 2000.

The talk will show how to use these new features to make your QML code behave in a more predictable way and to enable compilation to C++ via the Qt Quick Compiler.

About the Speaker: Ulf Hermann has been working with the Qt Company since 2013. He is the maintainer of the QtQml module and the QML language. Currently, he is working hard to make QML more efficient by compiling ahead of time to C++.

Understanding the Qt Stack Trace

Nov 29, 13:50-14:35

Abstract: Writing code means debugging code, and that means setting breakpoints and looking at stack traces. When using any framework, much of the stack trace involves code from that framework. In this talk, we will go through some of the Qt internals that are exposed through the stack trace, and try to understand what's going on before the execution hits our application code.

QML Code Reload: Discover What’s New

Nov 29, 14:40-15:10

Abstract: Code reloading is a technique that allows developers to update the application’s source code at runtime. By using code reloading in your Qt Quick project, you can achieve short iteration cycles and speed up development. This talk discusses how to implement code reloading in Qt-based applications for Embedded, Desktop, Mobile, and WebAssembly. We explore different techniques, their advantages, and drawbacks, as well as the best tools to use for optimal performance. The audience will gain valuable insights about Qt 6 and why it is an ideal framework for code reloading. Through practical examples and demos, attendees will discover how to create high-quality applications with fast iteration cycles.

Abstract: Qt and Python are around the same age, but both technologies evolved independently. The moment Python bindings were available for the Qt framework, both stories started to be related. Then the question is: what's the impact of providing bindings in other languages? In this talk, you will learn about the evolution and influence between Qt, C++, and Python. Additionally, you will learn how Qt for Python is closing the gap between these two worlds and the influence on Qt by learning about the current state and future of the project. Thoughts about the interaction with other languages like Rust and Carbon will be presented as well, but no previous knowledge is required.

Verification of Safety Designs – Freedom from Interference

Nov 29, 09:00-09:30

Abstract: Safe operation of any embedded device is enabled by a rigorous architectural design. In ISO26262 mixed-ASIL systems, the architecture needs to ensure freedom from interference among the safety-related partitions and between safety-related and QM partitions. After a safety architecture has been defined and verified, static analysis can (and should) be used to demonstrate compliance between implemented source code and this architecture. This presentation highlights one way to apply an architecture check for the aspect of freedom from interference.

About the Speaker: Steffen Keul studied Software Engineering at the University of Stuttgart and gained experience with static analysis during his post-graduate research on static analysis of concurrent systems.  For four years, he worked in product management and pre-development of automotive basic software with a focus on functional safety according to ISO26262. In 2017, he joined Axivion's Solution Engineering team. In this role, he strives to find the perfect static code analysis solution for every customer project.

Towards Autonomous GUI Testing

Nov 29, 09:50-10:20

Abstract: GUI testing is expensive. While automation helps with reducing the cost and time required for executing tests continuously, it still requires identifying and implementing meaningful test cases. With the spirit of Shift-left Testing, we intend to execute dynamic tests on GUI applications in earlier stages of development, to capture major mistakes early and cost-efficiently. Therefore, we present ideas for autonomously testing GUI applications and discuss some of the various challenges we anticipate and how we plan to approach them.

Model-Based Testing - What's That Model Good For?

Nov 29, 10:25-11:10

Abstract: Software development tends to gain momentum in complexity, and so do tests. How do you test complex applications? How do you find the best path to cover as much as possible with the least tests? Should I go left or right, or turn around? Are we lost? We abstract complexity with models, which we can explain. In this session, we are going to abstract complexity with models. There will be a brief introduction to Model-based testing, and then we will walk the path. We will leverage this concept and Squish to test our Qt application.

A Vision of Future Collaborative Qt Quality Assurance in Distributed Teams

Nov 29, 11:15-12:00

Abstract: This presentation provides a near-future vision of how quality assurance can look like when multiple stakeholders together need to look at software quality data even if they are not in the same room. The vision is driven by several ongoing trends in software engineering. First, the software is increasingly developed in distributed teams. Second, a more holistic approach to quality assurance is taken in which data from many sources are combined, such as the findings of static code analyzers (e.g., gathered by the Axivion Suite), coverage and failure data of dynamic tests (e.g., collected by froglogic's tool set), or change data (e.g., retrieved from a version control system) to name a few. Third, the need to fuse and abstract quality data from the lower level of source code to an architectural level enabling all stakeholders to see the bigger picture. This vision materializes in our ongoing research project in which we create virtual rooms where members of distributed teams can meet to take a common look at their software and its quality. Based on the popular code-city metaphor, the architecture, and implementation can be visualized at a level of abstraction suitable for stakeholders from different domains (e.g., developers, testers, or managers). The virtual room can be entered remotely using classic desktop computers as well as modern AR/VR hardware. The members can interact with the visualization and take on their own individual perspectives. They can also see all other members represented by avatars, which allows them to trace the interactions of all others with the visualization and to see their gestures and mimics enabling non-verbal communication.

About the Speaker: Rainer Koschke is a full-time professor of software engineering at the University of Bremen in Germany and heads the software engineering group. His research interests are primarily in the fields of software engineering, program analyses, and software visualization.

Tit for Tat: How (Not) to Bully a Static Analysis Tool

Nov 29, 13:00-13:45

Abstract: Are you mistreating your static analysis tool? Modern static analysis tools are able to spot a large number of critical runtime defects (e.g. overflows or divisions by zero). However, they may report false positives, which result in a manual review or rework of the code. We show examples of coding patterns that can make the life of a static analysis tool complicated and might cause an increase in false positives - and also what to do to help the tool. As an example from practice, we take a look at the implementation of a message-passing primitive and check how well it can be analyzed. The aim: make life easier for the analysis tool – and you.

Continuously Test Embedded Systems Keyword-Driven with Qt's Squish

Nov 29, 13:50-14:35

Abstract: Modern embedded systems are always connected, and information can be retrieved by a variety of applications on multiple platforms: web, mobile, and desktop. Therefore, end-to-end tests need to automate all those endpoints, platforms, and APIs at once. This can lead to a complex and heterogeneous test environment, very quickly. In this talk, there will be shown how Qt's Squish together with keyword-driven testing according to ISO29119-5 is able to reduce complexity from such a test environment by unifying the test adaption layer and reaching most of the stakeholders involved in QA besides developers.

Code Security Beyond Development and Safety Guidelines: Architecture Security

Nov 29, 15:15-15:45

Abstract: As the consequences of cyber-attacks are becoming increasingly severe, ensuring the security of software systems has become a necessity. Compliance with security coding guidelines can be ensured by static analysis. However, there are additional security threads caused by software architecture violations and bad modularization decisions. Since the manual review of architectural compliance is cumbersome, erroneous, and expensive, automatic static verification of software architectures is desirable. We will show how security issues and their requirements for architectures can be modeled suitably for automatic verification.

Unleashing the Power of Qt and MVVM for Custom UI Development: From View to ViewModel and Back!

Nov 29, 13:50-14:35

Abstract: This talk will focus on the MVVM approach to UI development using the Qt framework, specifically on the strict separation of the UI's visual layer (View), its logic and data management layer (ViewModel), and the driving mock-data back-end (Model). By implementing ViewModel modeling, developers can create UI components that are highly modular, reusable, and easily maintainable across multiple platforms while allowing designers a greater degree of flexibility and total control over their UI designs. The talk will cover the technical aspects of this approach and its benefits in terms of UI design systems, usability, and performance. Attendees will gain insights into the benefits of ViewModel modeling and learn how to apply these principles to their own UI development projects using the Qt framework and Qt Design Studio.
