Libcamera: Making complex cameras easy! (Ecosystem Growth)
8:45 AM - 9:25 AM
A complex camera support library for Linux, Android, and ChromeOS. Cameras are complex devices that need heavy hardware image processing operations. Control of the processing is based on advanced algorithms that must run on a programmable processor. This has traditionally been implemented in a dedicated MCU in the camera, but in embedded devices algorithms have been moved to the main CPU to save cost. Blurring the boundary between camera devices and Linux often left the user with no other option than a vendor-specific closed-source solution. To address this problem the V4L2 community is collaborating with industry leaders to develop a camera stack that will be open-source-friendly while still protecting vendor core IP. Libcamera is under active development and interested vendors have the opportunity to contribute and provide feedback to ensure we cover all use cases before the API is finalised.

RTL experince in Linux (Platform Diversity)
9:35 AM - 10:15 AM
RTL experince in Linux environment not developed like LTR one. As I use Linux since Mandrake 9, I see RTL in Linux isn't mature like in other environements like Mac and Windows. RTL used as a main and secondary languages for about 20% of the world. Making Linux better for them is important. In this talk I'll scoope issues with RTL, and how to solving it.

10:20 AM Next Generation Application Management
Next Generation Application Management (Ecosystem Growth)
10:20 AM - 11:05 AM
A Linux desktop's sole job is to connect users to their applications. There used to be a time where one application was a process. 'ps' would show one easy to manage entry. Now Discord in a flatpak is 13(!) procesess. Have two electron instances and a system-monitor is useless. We have backgrounds services that linger with indecipherable names. It doesn't scale anymore on the desktop. We need metadata. This is a solved problem with new kernel features. CGroups are used commonly for your system services. Any sysadmin won't deal with an Apache process, but the whole webserver as one cgroup. By embracing this not only do we have metadata providing a single-truth of the launched context, but also expose all of the kernel features reserved for cgroups. Separate network namespaces, hard CPU quotas, Out-of-memory protection that works, we can expose this either as transient modifiers or as sysadmin overrides. We've been tackling this on both the GNOME and KDE side. In this talk we come together to talk about what we have each done on our respective sides. Where we've found common ground to common problems, as well as our plans for where we take the linux application ecosystem in the future.

Snaps are confined, standalone Linux applications bundled with all the necessary dependencies to run independently. They are designed to simplify development and deployment of software, and make it easier for users to discover applications. Sounds like an enticing idea ... but where do you start? This presentation unveils the boffinry of the snap ecosystem. It introduces and highlights the steps needed to package applications as snaps, including the underlying snap technology and mechanisms. The session will cover the building blocks used in the snapcraft.yaml file required to turn Linux applications into snaps, with overview of capabilities, confinement, interfaces, plugins, and more. By moving all the cruft behind the scenes, now all it takes is one simple recipe to build software with fun and ease.

Watch a Linux Game Get Built in Real Time (Platform Diversity)
5:30 PM - 6:10 PM
There is a lot of discussion about how apps *should* be built, but has anyone watched an app *actually get built*? Behold, a something-hour time slot where you literally just watch Linux game porter Ethan Lee build Linux games. What you will see is completely uncensored and is actually, seriously how he builds programs that may very well be installed on your very computer at this exact moment in time. No joke. Compare the resulting footage to everything else you see at the summit and attempt to measure the delta accordingly. Ethan "flibitijibibo" Lee has developed over 60 commercial Linux games over the past 8 years, including FEZ, Celeste, Streets of Rage 4, Bastion, Transistor, VVVVVV, Super Hexagon, Proteus, Eversion, Dust: An Elysian Tail, 5D Chess (yes, an actual playable 5D Chess), and Dream Daddy: A Dad Dating Simulator. He is extremely sorry for this so-called presentation.

The Prism of Collaborative Marketing in Open Source
- Melissa Logan
7:05 PM - 8:05 PM
The role of marketing in open source is to increase usage and adoption, and collaborating with members of your ecosystem can vastly extend your reach. But developing a shared vision across multiple organizations with different goals requires as much finesse as working on open source code itself—neutrality, trust, and a willingness to find common ground are crucial. How do you create an architecture of participation? This keynote demonstrates how marketing, refracted through an open source ecosystem, expands the spectrum of outcomes more than any single organization acting alone. About Melissa: A 20-year veteran of technology marketing that began in the dot-com era, Melissa Logan pioneered the role of the open source marketer that helped fuel the rise of open source software development. She led marketing for open source projects at The Linux Foundation and founded Constantia.io, a firm that supports open source projects/companies such as Apache Cassandra, Tidelift, and others. Previously, she worked with companies as diverse as Microsoft, Isilon (acquired by EMC), Octarine (acquired by VMware), Meridian (acquired by Aruba Networks), and others. Logan loves all things open source and community, and spends the rest of her time riding horses in the vaquero style. She launched the Sexism Field Guide in 2018 to help people identify and confront all forms of sexism. Logan graduated from the University of Oregon with a degree in Journalism and Political Science, but only uses one of those.

Presentation: Linux Graphics 101 (Ecosystem Growth)
- Rohan Garg (Collabora)
8:00 AM - 8:40 AM
The ever growing popularity of ARM devices has meant a new market for Linux apps. However, unlike conventional platforms where we enjoy the stability of a well tested graphics stack, platforms based on the ARM architecture tend to be quirkier. In this talk, I'll be talking about the basics of how the Linux Graphics stack works touching on how technologies such as DRM, DRI, and Mesa interact with each other and the history behind how we've come to the current Gallium design in mesa. At the end of the talk attendees should have a better understanding of what goes on behind the scenes in the graphics world and a high level understanding of the Mesa/DRM architecture. Furthermore, this should help Linux app developers gain a better understanding of mesa and allow for faster debugging of graphics issues on ARM devices.

GNU Health is social project that uses Libre technology to improve the health care system around the world. In this talk, I'll be talking about the GNU Health Federation ecosystem and MyGNUHealth, the mobile and desktop application. We will talk about the technical components (**KDE, Qt, Kirigami, Python**... ) and how we can deploy MyGNUHealth in every desktop computer, as well as in mobile devices, such as the **PinePhone**. I will go into details about the communication mechanism across the participating nodes in the Federation, the role of the GH message server (**Thalamus**) and the security aspects. Finally, we'll dedicate sometime to the functionality of the main components and nodes, from Personal Health Records (**PHR**), to social medicine, bioinformatics, **epidemiology**, medical genetics, **personalized medicine** and **cancer research**.

UI/UX Tips & Tricks for developers (Platform Diversity)
- Ecaterina Moraru
9:35 AM - 10:15 AM
I will present some general UI/UX tips & tricks that will help you design better. Everyone should know the basic principles and patterns of design, and once you understand them you will naturally integrate them in your work. UI/UX is a craft. The more you practice it, the better you are at it. Some people argue that you need to have 'good taste' in order to be a designer, to be the 'artsy type'. While this might be true for Graphic Design, Branding and Visual Arts in general, when it comes to Interface, Interaction and Product Design, the focus is more on practicality and 'common sense'. Understanding basic design principles will provide an advantage when creating or contributing to your favorite Open Source project.

10:20 AM - 11:20 AM
About this talk: In this talk, a Linux kernel developer gets to complain how his normal "test case" i.e. userspace code, could do better when it comes to a whole range of different things that have been learned over time by maintaining a stable interface to the kernel for 20+ years. About Greg: Greg Kroah-Hartman is a Fellow at the Linux Foundation. He is currently responsible for the stable Linux kernel releases, and is a maintainer of the USB, TTY, and driver core subsystems in the kernel as well as other portions of the kernel codebase that he wishes he could forget about.

Revolutionizing the audio experience on the desktop with PipeWire (Innovation)
- George Kiagiadakis (Collabora)
4:00 PM - 4:40 PM
PipeWire has been making a lot of progress lately on providing a drop-in replacement audio server that unifies the PulseAudio and JACK APIs. Recently, it was announced that it is ready for general testing and at this rate it should be ready to be distributed as a replacement of PulseAudio in 2021. Looking in the future, though, we need to ask ourselves... how can PipeWire improve the user experience? Does it actually bring any value to end users that have never heard of JACK before? Does it bring any changes? In this talk, George is going to give an overview of how a PipeWire-enabled system looks like and behaves at the moment and then take a glimpse in the future, looking at ideas, which are already being worked on, that could revolutionize the user experience in an environment as complex as the desktop - with your help!

Can your app run on a mainframe? (Ecosystem Growth)
- Elizabeth K. Joseph (IBM)
6:15 PM - 6:55 PM
Modern mainframes feature state of the art hardware and software, including Linux, which is now the fastest growing operating system for the platform. Many organizations that are now taking their first steps into Linux, or moving workloads back to the mainframe, to take advantage of the security enhancements and software now available for Linux. In this talk, I'll cover what is involved in porting an application to the big-endian architecture, as well as free (as in beer) and open source tools and services available to developers to build, test, and release applications for the platform. I'll also talk about how the IBM Z Ecosystem Team has been working with individual developers, the Linux Foundation’s Open Mainframe Project, various Linux distributions, and specific open source projects to port their applications to the mainframe architecture. I will conclude by touching upon about how apps running on Linux can communicate with the more traditional mainframe back-ends, including open source projects like Zowe that modernize these interactions with an API and more.

Introduce the attempts and insights made by the Ubuntu Kylin development team in building a Linux application ecosystem. First, by building the UKUI desktop environment and encapsulating the SDK, users can get a better experience and facilitate application development to support the development of the application ecosystem; second, actively lead or participate in open source application projects to make open source applications more stable, practical and easy to use ; Finally, actively promote the migration of popular commercial software vendors to the Linux platform, provide human support when they do not have Linux engineers, and form a virtuous circle.
8:45 AM On open source apps funding - Manuel Genovés Monzó (GNOME)
On open source apps funding (Legal and Licensing)
- Manuel Genovés Monzó (GNOME)
8:45 AM - 9:25 AM
# On OSS Funding It's well known: OSS is underfunded. That has a lot of implications in several levels, which I won't discuss here. Just for the sake of completeness, I'm gonna point a few of them: - OSS maintainers need to eat. Since OSS doesn't usually let people make a living out of it, they end with other day jobs. That means OSS projects are always at risk of becoming unmaintained, and increases the bus factor of projects a lot. - While OSS maintainers aren't able to monetize their work, big companies usually do, which is at least problematic. - That also means the culture surrounding Linux is "everything is free", so it's less attractive to new developers which want make a living out of their programming. That means a smaller app ecosystem, with a lot of abandonware. ## People are not money-grubbing The truth is, people want to pay for things! And software is no exception: see how well the AppStore or Steam do in that regard, so what's the issue with OSS? Why people don't throw money at developers? ## OSS is a model based in charity Say donations, say charity. Even if factually donating $5 to SomeApp and buying that app for $5 is the same, psychologically those are two very different things ### On the perceived value We live in a capitalist world, and we cannot omit that in our analysis. In capitalism value and perceived value are by no means the same thing, and perceived value scales with the price point put to something, not by their inherent value. Even more important, the price point doesn't necessarily need to match the price the customer ends paying. That's why sales work as a commercial strategy: you put the value with the original price tag, and by making a sale you offer customers the idea that they may get the same value by paying less. If OSS is offered without a price tag, people just will assume its value is lower than the same product with a price tag, even if you allow to not pay anything at the end. More on that: even if we hope to value an app by their inherent interest, that valoration will never be accurate. Developers don't know how to predict how many hours of development a task will take, regular people even less. Since things Just Work TM is easy to assume that things were easy to develop. The strategy of putting an "hours invested in this" is widely used in web products, I think we can assume with some success. ### Friction and expectations Even if the user knows the value of the app they want to use, probably they won't donate to it a cent. This is due to two things: friction and expectations. I'll talk first about the latter. While a donation-based model lowers the fear of loss you may have in a payment-based model, it ups user expectations _a lot_. Why is that? If we think about other donation-based models they're usually built around the idea of "we're doing a public good and we need your trust and money to keep doing it". Well, trust is a hard thing to give, and you usually want the money you donate to be well employed. Not only that: money given to donations usually is a low-priority, highly constrained part of your typical budget. If in the mental model of someone there is X money for groceries, Y money for non necessary things, and Z money for charity, you're directly competing for a quite constrained budget with some high moral non-profits. Not the best place to be for a text editor. Then you have friction, and it affects both charity-based and payment-based models. It's easy: given two paths, people will always follow the one of least resistance. And friction plays a huge role on that. If it's easier to pirate than to pay $2, people will pirate. It suffices to say that having a donation link inside an About dialog which opens a new window and then asks you to input your credit card, your PIN, then check your mobile to confirm the transaction... won't work. _Is way easier to just keep using the application_. If each time you want to buy an app in Software you need to do about the same, people will avoid selecting paid apps. ## The path to a frictionless paid ecosystem Say we implement payments on GNOME. That needs to be done on a Platform level, for several reasons: - We need the payment system to be trustable - We need it to be a fairly centralized system who offers an API to applications -> again, trust - We need it to be frictionless: you put your payment data once, and after that if you want to make a payment you just press a button. - We need to offer incentives for entering the payment data: In all seriousness this could be a very interesting point for GNOME to offer some services (config backups, secure mail, cloud services for enabling apps to have cloud capabilities such as sync of data, who knows) And on top of all of that, we need to put a price to our apps even if we go a pay-what-you-want route, and/or showcase how much work goes into making them.

High quality localisation is essential to great user experience for most people in the world, yet the process of translating applications in the Linux / FOSS ecosystem is often more difficult than it needs to be. The problems faced by translators may not be obvious to software developers, though. In this talk I try to give advice to developers and communities who would like to have their applications translated better, based on my experiences in translating various FOSS software. Key points: * Give credit * Offer modern infrastructure * Be responsive * Enable communities * Verify, but trust * Provide context * Avoid hard-coded assumptions * Don't reinvent the wheel * Encourage fixing issues at the source * Consider sustainability

Brickless battery saving with Ubuntu Touch (Innovation)
- Dalton Durst
5:30 PM - 6:10 PM
On the Linux Desktop, we value always-on, always-connected, and always in-sync applications. Our data, discussions, and research must always be available to us. We must always be instantly notified of important changes to the state of our chats, computer, or the world around us. Until we shut the laptop lid. Once the lid is shut, the laptop can safely become a brick until the lid is opened again. Your phone likely doesn't have the luxury of becoming a brick whenever you put it in you pocket. You expect that important changes to the world around you, whether targeted toward you specifically or people sharing your interests, will command your attention. Meanwhile, you also expect your phone to last at least a whole workday of mixed use and sleep periods. It might have a more efficient processor and smaller screen than your laptop, but it also has a much smaller battery. There's no way your phone would last all day if it was in the same "active" state that your laptop is with its lid open. But likewise, your phone doesn't become a brick as soon as it falls asleep. How? Your phone isn't always active. It just fools you into thinking it is. As we move Desktop Linux further into form factors like tablets and candybar phones, we'll need to provide this illusion of continuous connectivity to more applications. This talk is all about how Ubuntu Touch can manage calls, SMS, Telegram messages, news broadcasts, and infrastructure alerts while still providing multi-day battery life.
