Session descriptions for Monday
QtCore discussion
Thiago Macieira
Review of latest changes and planning for upcoming work, including preparation for Qt 6 (other than containers). Ideas:
- hashing function update; expanding the hash seed to 64- or 128-bit
- QRandomGenerator and providing a PRNG of good quality (Mersenne Twister or Chacha20)
- QIODevice for Qt 6
3D
Laszlo Agocs & others
Let's discuss the 3D story.
Improving texture support in Qt Quick
Giuseppe D'Angelo
Qt Quick offers an extremely limited support for using non-RGB(A) textures, such as compressed texture formats and/or prebaked atlases. See the discussion and the subtasks of https://bugreports.qt.io/browse/QTBUG-59855 for a discussion.
Qt wiki (wiki.qt.io) maintenance
Tero Kojo
How do we make the wiki more useful to everyone? The basics are there, and in the past wiki weeks helped boost the place, but they are not a long term solution. Also moderation needs to be discussed, we have to have it in place because of spam, but we need a bigger moderation team, so that edits don't get stuck for several days.
Open governance and Jira practices
Santtu Ahonen
How we use Jira public projects, Epics, User stories and Tasks & Bugs to track and share work targets? As far as I can tell there seems to be project specific practices and if nothing else the discussion is about sharing those practices (e.g. why we use so many Epics instead of User Stories?) and see if there is some parts where we could or should align (e.g. how to mark fixtarget releases?). This links in to The Qt Company internal use and practices for Jira use, we cannot plan our own internal Jira usage in vacuum without the contributors.

Session descriptions for Tuesday
Qt6 containers
Thiago Macieira
Discuss whether Qt 6 containers should:
- be copy on write or not
- build upon the C++ Standard Library containers or continue independent
Pretty Printing With Qt-Creator
Stéphane Petithomme
The Presentation is about So-ADE Debugger, a Qt-Creator plugin extension that allows to create custom Pretty Printer in few click for Qt-Creator. It comes with a few hundreds pre-configured Pretty Printers (Boost Library, Qt, Library, Std Library, Verific Library,.. ). During the session you will learn how to customize existing Pretty Printers and create you own one to greatly improve your productivity. I am very interested about feed back and comment to further improve the plugin, which will be make open source by the conference.
BOF Qt OpcUa
Frank Meerkötter
A quick get together for people interested in OPC UA. I'd like to hear about your use-cases for Qt OPC UA. I'd also like to discuss the pros/cons of having a Qt-based implementation at all. Is there mostly interest in a C++ API? What about a QML API? What parts of OPC UA are used in the field? How to get the existing Qt OpcUa based code base off the ground? Is the approach of wrapping an existing implementation sane? Do we wrap the right implementation? Would it be a way forward to build on top of open62541?
DTLS & CoAP protocol
Adrien Leravat
We are contributing a CoAP protocol module for Qt, and would like to hear your inputs regarding current implementation and API. CoAP is a protocol similar to HTTP used in IoT contexts. I will explain a few use case, current status of contribution, and what's to be expected next. We can then have a look at the API and how it is designed to discuss openly these aspects.
Open-source AR with Qt
Martin Voelkle and Stéphane Magnenat
We will present a fully-functional augmented-reality solution using natural marker images, building on Qt 5 and OpenCV. Our solution uses state-of-the-art algorithms but is not yet as fast as competing closed-source products such as Vuforia. We will present the design choices, the architecture, the Qt integration, and discuss challenges and potential improvements. A demo will conclude the presentation.
CI
Tony Sarajärvi
Open discussion related to the change from VMware to openNebula, the new infrastructure, flakiness of the system and a good amount of Q&A.
C++17, C++20 and beyond
Ville Voutilainen
A presentation about what's in C++17 and what is forthcoming in C++20 and future standards.
