What's next for GNOME infrastructure (Project Organisation and Governance)

• Bartłomiej Piotrowski

GNOME infrastructure team regularly schemes how to complicate the lives of developers and contributors even more. Come and learn what our plans are for the upcoming years, and how can you contribute!

Accessibility update: the Python stack, Rust, and DBus (Application Development and Deployment)

• Federico Mena Quintero

This talk continues upon the work from last year's, on the state of the accessibility infrastructure for GNOME and free systems in general. While the base C libraries continue to get cleaned up, I have started exploring the Python part of the stack. In terms of technology, the Python stack is in a similar state to how the C stack was: no CI, few tests that don't get run automatically, and loads of little hacks to keep it working. As part of all of this, I have found the perfect excuse to start replacing the DBus marshaling code in C with Rust. Come along for an exciting ride!

The New Printing GUIs: GNOME Control Center and Common Print Dialog Backends (Application Development and Deployment)

• Till Kamppeter (OpenPrinting/Canonical)

With the background of all modern printers being driverless IPP (Internet Printing Protocol) printers we are switching to an [all-IPP printing architecture](https://openprinting.github.io/current/#the-new-architecture-for-printing-and-scanning) without classic printer drivers. This changes also the needs of the GUI for setting up printers and for printing itself. 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 [backends of the print system developers](https://openprinting.github.io/achievements/#common-print-dialog-backends). In this talk we want to show the state of the art of the development of the GUIs and also demo them and in the end we will have a discussion with the audience.

Maintaining healthy upstream relationships as a small team (Community Building and Diversity)

• Dylan McCall

For over a decade, the Endless OS Foundation has balanced creating new products with open source software while maintaining healthy relationships with upstream projects. Forks are inevitable, but those sustainable, long-term partnerships are immensely valuable. This presentation will explore techniques for effectively communicating upstream, fostering a culture of collaboration, and managing disagreements. Using real-world examples from our own experiences with projects like GNOME, we will highlight the benefits and challenges of thinking upstream first while building for a unique vision.

Reducing power and bandwidth use in apps to keep users happy (Application Development and Deployment)

• Philip Withnall (Endless)

Users who are on battery power, or using a mobile connection, can sometimes have a frustrating experience with apps which use lots of power, or keep downloading things. In some cases, this can lead to large bandwidth usage bills before the user realises. The GNOME platform provides ways to change app behaviour to save power and bandwidth when appropriate. This talk will go through some examples of them. The talk is aimed at app authors.

How GNOME Gets into Ubuntu (Use of GNOME by Users)

• Jeremy Bícha (Canonical Ubuntu)

GNOME produces two major releases every year. Ubuntu also has two releases every year. In this talk, a longtime Ubuntu Desktop team member will discuss how GNOME features and bugfixes get into Ubuntu.

How to make a delightful app listing (Application Development and Deployment)

• Cassidy James Blaede (Endless OS Foundation)

Over the years I’ve helped build an app ecosystem built on open standards, and today I work with organizations deploying computers that run Linux to dozens, hundreds, or thousands of people at a time. One of the recurring places I notice app developers struggling is their app’s metainfo—the structured data that forms an app’s listing across app stores including GNOME Software, Flathub on the web, KDE Discover, and more. Let’s fix that! In this talk, I dig into: - Who this talk is for - Why “marketing” is not a bad word - Where and how this metainfo actually shows up - Neat things you can do with metainfo - Examples You don't need to be an app developer to attend this talk, but my hope is that any app developers who do will have actionable advice for immediately making their apps more attractive in every app store on Linux.

The best testing tools we’ve ever had: an introduction to OpenQA for GNOME (Design of User and Developer Experiences)

• Sam Thursfield (Volunteer)

How do you write the testsuite for an entire graphical desktop environment? Desktop and distribution teams have been struggling with this question for more than a decade, and our combined efforts are starting to pay off. The combination of Gitlab, BuildStream, GNOME OS and OpenQA is the most powerful toolset we’ve ever had for ensuring high quality GNOME releases.

Rust: The state of the bindings (Application Development and Deployment)

• Bilal Elmoussaoui

Rust usage has been increasing quiet a lot lately inside the GNOME community, from libraries, and GStreamer plugins to applications. In this presentation, we will go through what the GNOME <3 Rust community has achieved this in the last two years.

State of the shell (Application Development and Deployment)

• Jonas Ådahl (Red Hat)
• Georges Basile Stavracas Neto (Endless OS Foundation)
• Florian Müllner
• Carlos Garnacho (Red Hat)

With GNOME 43 and 44 released, there is much to celebrate since last year. This session will go through the improvements done since last talk, and cover highlights and latest development plans in Mutter and GNOME Shell.

VanillaOS - not just another distro (Design of User and Developer Experiences)

• Pietro di Caprio

Vanilla OS is an *immutable* and *atomic* Ubuntu based point release distribution. In the last months we announced that we are changing base, switching to Debian Sid, released as OCI image making it easier to release a desktopless version allowing the community to create non-GNOME flavors and OEMs to customize the distro with additional drivers. In this talk we're going to talk about the user experience idea that drives the full development of VanillaOS and the entire concept that is born from the experience on other distributions (like Fedora Silverblue with OSTree) and systems (like ChromeOS on Chromebooks). We're going to talk about how we aim to simplify the migration to Linux thanks the custom guided *first setup* and the optimized installer. We're going to talk about reliability, security and working modes both for office users and developers thanks to the Sub Systems.

Slow progress on app save/restore support (Application Development and Deployment)

• Philip Withnall (Endless)

Over the last year, some progress has slowly been made on adding support for saving and restoring app state across restarts. This requires changes in gnome-session, GTK and GLib, as well as in apps themselves. This talk will give an overview of where we’re at, the architecture being used, and what’s left to do. It will be a technical talk, and is aimed at toolkit developers and adventurous app authors.

Using Cloud VMs as your Personal Computer ft. GNOME (Use of GNOME by Users)

• Hrittik Roy

In this talk, we will explore the use of cloud VMs as a personal computer and how cloud VMs can provide improved performance and accessibility, making them an ideal choice for remote work and collaborations. The talk will also highlight how cloud VMs can be particularly beneficial for new contributors looking to get started with open-source development. With a cloud VM, they can easily set up and configure their development environment without worrying about hardware limitations or compatibility issues. Lastly, we will discuss how using a GUI like GNOME on a cloud VM can help users access GUI applications and make their work more efficient. By leveraging GNOME's built-in tools, users can seamlessly switch between local and remote workspaces, making cloud-based development a seamless experience. Overall, this talk will showcase the advantages of using cloud VMs with GNOME and how they can enhance the user experience and developer onboarding.

Toolbx: developing GNOME on OSTree based OSes (Application Development and Deployment)

• Debarshi Ray

People are rethinking how Linux distributions for client and edge devices work. There's a rough consensus around shipping the operating system as hard-to-modify OSTree images and the applications as Flatpaks. This promises painless upgrades, separation between the OS and applications, and secure cross-distribution applications. Many of these distributions are heavily reliant on GNOME and vice versa. GNOME OS, Fedora Silverblue and Endless OS are prominent examples, arranged in increasing order of modifications to vanilla GNOME. However, these OSTree-based OSes present some problems when setting up development environments. The OSTree OS images are intentionally minimal and hard to change. They don't even come with traditional package managers like APT or DNF. Hence, it's difficult to install any development tools, editors or SDKs. How do we use these OSes to hack on GNOME and the applications that we want people to use on them? Come to this talk to find out.

Nautilus: Sailing into new seas (Application Development and Deployment)

• Christopher Davis
• Peter Eisenmann
• António Fernandes

Eazel has created the Nautilus project at the turn of the millennium. The *nautilus* is a marine shell mollusk which has survived relatively unchanged for hundreds of millions of years, for which it's considered living fossils. Over 2 decades later, the GNOME Files core application still carries on the *nautilus* name. However, far from a living fossil, it's evolved so much that it's almost unrecognizable! Thanks to many contributors, it keeps evolving and adapting into new seas (GTK 4, flatpak, portals, mobile,...). A talk with bit of history, latest developments, and future plans for a core component of the GNOME user experience. Welcome aboard!

Your app everywhere, just in a Snap! - Interactive Workshop (Application Development and Deployment)

• Till Kamppeter (OpenPrinting/Canonical)
• Jesús Soto (Canonical)

Have you already thought about how the GNOME applications you develop get distributed to end users? Often developers only provide the source code. So for not so tech-savvy users the major distributions need to pick up the project and package it, and maintain it for new releases. This is why there is a need for distribution-independent, secure, and easy-to-use packaging, like on smartphones. This exists also for Linux ... Among the options, there is [**Snap**](https://snapcraft.io/about)! Applications are easy to find in the Snap Store and they are installable on most Linux distributions. **We are here to introduce you to the Snap packaging format and guide you on how to create your first Snap. Hands-on exercises will be done on your laptop. We will start with simple GNOME applications and in the end we will help you snap your own application.** More about Snap: [The Powers](https://www.youtube.com/watch?v=TfB6QwR2GYg), [The People](https://www.youtube.com/watch?v=ido6kGmSHWI) Big Blue Button: BoF Rm 1 Venue: Rm 336
