GTK Maintainer - Matthas Clasen and Sri Ramkrishna talk about Linux App Summit in this short podcast video. Check it out! This is our first video post so feedback is really welcome especially if we get some things wrong.

This presentation aims to inspire developers to build beautiful, free (as in freedom) apps and leverage the powerful tools and community available through GNOME Circle.

Alireza Shabani is a developer from Iran. He enjoys coding, making music and doing graphic design.

The Linux App Summit (LAS) brings the global Linux community together to learn, collaborate, and help grow the Linux application ecosystem. Through talks, panels, and Q&A sessions, we encourage attendees to share ideas, make connections, and join our goal of building a common app ecosystem.

A presentation on recent design developments in KDE Plasma. Building Plasma's next generation design model for a correlated and faster process to develop applications using the power of design systems and open source distributed communities.

Andy Betts is a long time KDE contributor. Andy leads the Visual Design Team at KDE and is also a member of the Community Working Group. Additionally Andy has been a KDE e.V. Board member and currently assists in many capacities involving graphical design. Andy's work involves reviewing graphical changes to the system, providing improvements, maintaining visual conventions and developing new concepts for Plasma. In his professional life, Andy is a Manager of User Testing for a large cloud services provider. Andy resides in the United States.

Symbiosis in open source refers to the mutualistic relationship between the community of contributors and users that drive the development of open source software. It involves a give-and-take relationship, where users benefit from the contributions of developers, while developers benefit from the feedback and support of users.

This interdependence is what fuels the success of open source projects, and enables them to create high-quality, innovative software that meets the needs of users around the world.

Are you an app developer? We want to hear about your Flathub experience! We're running a survey to collect information about how app developers use Flathub and how Flathub could work better for them. During this focus group, we'll walk attendees through our survey questions and have time for discussion and feedback.

This workshop is open to all, but survey questions and discussion will be geared toward app developers with some Flathub knowledge.

Information & Communications Technology currently accounts for 3% of global CO2 emissions. If nothing changes, it will rise to over 30% by 2050. Often overlooked is the crucial role that software design plays: software determines the energy consumption of hardware, and for how long devices remain in use. Nevertheless, environmental harm driven by software design is largely unknown to most people … let alone that users can already do something about it with Free Software.

Energy efficiency AND energy conservation are critical, and both can be achieved now by adopting software meeting the Blue Angel criteria. Developed by the German Environment Agency, the ecolabel recognizes user autonomy and transparency, two pillars of Free Software, as critical for sustainability goals. In fact, Free Software is already fulfilling most, if not all, of the award criteria's user autonomy requirements. In this talk I will provide an overview of the environmental harm driven by software. I will link the inherent values that come with a Free & Open Source Software license to sustainable software design. Finally, I will provide an overview of the work of the KDE Eco project and the sustainability goals of KDE.

This is an introduction to the sommelier-core project, which tries to make it as easy as possible to package a Windows application for Linux. It uses Wine and Snapcraft to create a universal Linux package containing a Windows app.

The project is currently used by about 40 snaps for open and closed source software such as Notepad++, foobar2000, Cryptool 1, and TrackMania Nations Forever.

I explain the long and complicated history of the project, how it works, the future roadmap, and end with a small demo showing how to get started packaging your first Windows app for Linux.

The LinuxAppSummit is on its eighth year of existence. In that time frame, we've forged relationships between desktop projects, focused on application development and distribution. Where do we go next?

This is a panel discussion to cover a range of topics discussing where desktops can share a set of standards and where diversification is our strength. How will we tackle upcoming technologies like chatGPT/AI and Machine Learning that have started to become ascendant? Are they an opportunity or are they a threat? What have been our successes in the past eight years, and what should we be focusing on and planning for in the next 2 to 5 years?

This panel discussion will include desktop projects, toolkits, 3rd party developers, and distro partners.

With the background of all modern printers being driverless IPP (Internet Printing Protocol) printers we are switching to an all-IPP printing architecture without classic printer drivers.

This changes also the needs of the GUI for setting up printers and for printing itself and therefore at OpenPrinting we have mentored several Google-Summer-of-Code projects during the last years to do the required changes, both on the "Printers" module of the GNOME Control Center (2020, 2021, 2022 (1), 2022 (2)) as printer setup tool and on the print dialogs of GTK and Qt (2017, 2022). In further projects we will also treat the print dialogs of applications, like Firefox, Chromium, LibreOffice, ...

The GNOME Control Center will be able to list IPP services as available printers and not only CUPS queues and in the "Add Printer" part for setting up non-driverless printers it will also search for Printer Applications, which replace the classic CUPS drivers.

The print dialogs will not talk directly with CUPS (and other print technologies, like cloud print services) any more, but they will use the Common Print Dialog Backends concept.Here the developers of the print technologies (OpenPrinting in case of CUPS) provide their GUI-toolkit-independent print dialog backend and all print dialogs connect to these backends by D-Bus, so on changes in the print technologies the backends get updated and the GUIs and apps automatically support the changes.

In this talk we want to show the state of the art of the development of the GUIs and also demo them.

In this participatory workshop, we will test apps for usability with the keyboard and without sight using GNOME's Orca screen reader.
