3 Servo: Building a Browser Rendering Engine in Rust¶

Created by Mozilla Research in 2012 and now part of Linux Foundation Europe, the Servo project is a web rendering engine written in Rust. It combines memory safety and concurrency to create an independent, modular, and embeddable web engine that adheres to web standards.

Since the renewed activity in 2023, Servo has come a long way. Being written in Rust brings many benefits. Now, Servo is a more practical embeddable rendering engine, making it easier to embed in Rust projects.

In this talk, we will go through the benefits Servo gains from the chosen technology, such as Rust. We will talk about Minibrowser, which was developed by Servo developers. We will take a deep dive into several aspects of technical development going on in the project. At the end, we will explore how Servo is changing the browser, as well as open source world, what to expect, and how to get involved.

5 No, Open Source Didn't Destroy My Creative Agency¶

Fourteen years ago I started a creative agency with the usual mix of proprietary creative software. Seven years ago I took the bold and unusual step of completely replacing those tools with free and open-source alternatives. It has been a surprising, frustrating, fruitful, and enlightening journey.

This presentation is: 1) visually engaging proof that free and open-source tools can compete in a professional setting; 2) a case for why using and contributing to free and open-source software is a professional imperative; and 3) a practical roadmap to greater personal and creative freedom.

Aspiring artists, creative professionals, and anyone interested in the potential of free and open-source software will find this presentation relevant, entertaining, and inspiring.

7 Shining Light on the Open Source Supply Chain: The Risk in Community Health¶

Organizations are increasingly reliant on open-source software (OSS) to accelerate development and reduce costs. However, the health of the communities behind these projects is often overlooked, posing significant risks to the overall supply chain. This talk introduces the open source tool GrimoireLab that can shine lights onto those dark corners of your open source supply chain. We will also show how GrimoireLab was used in a novel Risk Assessment Model for the Maturity and Sustainability of open source dependencies, designed to address this critical challenge.

By using the GrimoireLab tool, combining concepts from the CHAOSS project and cloud-native deployment maturity models, our approach goes beyond traditional Software Bill of Materials (SBOM) analysis to evaluate the ongoing maintenance activity and community health of OSS projects. This enables organizations to:
- Assess the long-term viability of their open source dependencies.
- Make informed decisions about library selection and integration.
- Proactively mitigate risks associated with unhealthy or unsustainable communities.

This talk will delve into the model's design and implementation with GrimoireLab, using Kubernetes as a case study. By adopting this approach, organizations can build a more resilient and sustainable software foundation, ensuring the long-term health of their open source supply chain.

8 Matrix 2.0: Making Matrix Mainstream¶

Matrix is the open decentralised communication protocol recently adopted by the Ubuntu Community for realtime communication.

Much like Linux, Matrix has been on a journey - starting as a very developer-focused technology, and then making the transition to being usable by mainstream desktop/mobile users and being able to outperform closed proprietary alternatives. This has culminated in Matrix 2.0 - a set of new APIs which let Matrix clients such as Element X outperform the likes of Telegram, Discord and WhatsApp.

In this talk I'll give a VIP tour of Matrix 2.0 in my capacity as Project Lead of Matrix, and explain how we're trying to ensure that open communication eventually wins - and that Matrix becomes the real-time communication layer of the open Web.

10 Rust: Reaching for a Better Future¶

From its very begining, Rust has been a programming language about challenging the status quo. Rust's design is rooted in the belief that providing programmers with better tools enables them to design software that is more secure, reliable, and efficient. This belief leads Rust to a unique mix of advanced programming language features while giving to programmer control over low level details such as data layout when needed, all while giving particular attention to the ergonomics of the language. Yet Rust is not only its technical accomplishments. Rust is just as much an experiment in open and collaborative language design, and fostering a collaborative and supportive community. The mission of Rust is ongoing and there is still much to do to build on Rust's community and its technical contributions. This talk will provide a brief overview of the path Rust has made so far towards a better future and the work that still remains to be done.

15 How TCPX optimizes RDMA, and GPU-Direct performance for AI/ML, and HPC workloads¶

Remote Direct Memory Access is a technology that enables two networked computers to exchange data in main memory without relying on the processor, cache or operating system of either computer. GPUDirect RDMA is a technology that enables a direct path for data exchange between the GPU and a third-party peer device using standard features of PCI Express.

GPUDirect-TCPX is a custom and open-source remote direct memory access (RDMA) networking stack that increases the network performance of your accelerator VMs by allowing data packet payloads to transfer directly from GPU memory to the network interface without having to go through the CPU and system memory.

In the era of AI/ML and HPC, where data-intensive workloads demand optimal performance, maximizing network efficiency is crucial. Traditional TCP often struggles to keep up with the high throughput and low latency requirements of modern compute-intensive applications. This session delves into how GPUDirect-TCPX, a custom and open-source networking stack, revolutionizes network performance by optimizing RDMA (Remote Direct Memory Access) and GPU-Direct communication.

By the end of this session, participants will gain a comprehensive understanding of how TCPX unlocks the full potential of RDMA and GPU-Direct, empowering them to build faster, more efficient networks that meet the growing demands of data-intensive applications.

18 The Journey of KDE Plasma on Ubuntu Core¶

Last year, the Ubuntu Core Desktop effort has been introduced. It comes with a GNOME Shell based desktop. KDE Plasma couldn't be left out from such an effort, and this is how the "KDE Neon Core" idea came to be.

KDE Neon provides the latest KDE software packaged on top of an Ubuntu LTS base. KDE Neon Core is a similar idea but on top of an Ubuntu Core base.

This makes for interesting challenges both on the technical and community sides. Having another desktop running on Ubuntu Core pushed the envelop in term of expectations from snapd. It also brings lessons and future risks as desktop environments depend more on systemd directly.

In this talk we will show how KDE Neon Core is structured, what is does offer and its limitations. We will also explain the issues we encountered which led to patches in KDE software or in snapd itself. We will highlight how tests are produced and run on the KDE infrastructure. Finally, this will be an opportunity to reflect on the path forward and how to foster community involvement.

The talk should provide interesting insights for people curious about how the processes in a desktop session integrate, or about the interactions between snapd and applications.

If you want to hear battle stories on bringing another desktop to Ubuntu Core and learn what we discovered along the way, this talk will be for you.

21 Lowering the Burden: a GUI App for Everything¶

If we ever hope to move the Linux Desktop into mainstream, as developers, we cannot be constantly targeting ourselves. In order to target the general public, we need to stop solving problems with command line tools. However, if a problem already is solvable with command line tools, it should also be given a GUI app.

Zenity, a GNOME tool, gives us exactly what we need in most cases to do exactly this. Erich Eickmeyer, project leader of Ubuntu Studio and technical lead for Edubuntu, has written several tools to give regular users access to what would normally be done using the command line and editing configuration files, all using BASH and Zenity.

23 I am a developer!¶

“I photograph to find out what something will look like photographed”, said the great photographer Garry Winogrand. The genius of his work lies in his phenomenal powers of attention - his ability to see. Seeing is a deliberate act.

What do programmers “see”? How well do we do it?

I suspect that our world of software development is so full of intention that we fail to pay attention.

I want to pursue this, and I want to light up a potential dimension in programming that I haven’t seen explored. For example: why is it that a story or photograph can be about something, but we never hear of a computer program that is about something? Is it not possible? Or have we just missed it? We’re all familiar with love poems and love songs - could a "love program" exist? What would it look like?

I think we can answer all those questions in interesting ways, that connect programming to our understanding and appreciation of the world and our arts. I think that they can suggest new opportunities and ideas to us. It might not make us better programmers, but it could help us become more interesting ones.

24 Making the Thunderbird snap a first class citizen¶

There is a long history of Thunderbird being seeded on the Ubuntu ISOs. With this latest 24.04 Ubuntu release, there was a shift towards the Thunderbird snap by replacing the Thunderbird deb package with a transition package, much like was done with Firefox in 20.04.

As a former Canonical employee, I was able to bring the importance of snaps to MZLA (Thunderbird) and coordinate this transition in time for the Ubuntu 24.04 LTS and we've seen relatively little issues.

This talk will cover those important steps needed to get the Thunderbird snap ready for the limelight and highlight which conversations were needed between Canonical and Thunderbird (upstream) that would likely be needed by other projects looking to make the deb -> snap transition.

Come learn about how to get an upstream project interested in the snap packaging, and what steps to take to bring that snap to a top tier as well!

27 Introducing Ubuntu Flavors Design Squad¶

Design squad is a new initiative to connect flavors with volunteers who are interested in contributing design and similar skills. The flavors have unique challenges such as uneven workloads of design and branding tasks from release to release, and need of specialized skill sets. Even when the team has a design or art volunteer they tend to be a single person, or one time contributors.

Rather than a centralized effort, the squad aims to be an additional resource for flavors and a hub for volunteers who aim to contribute in this area.

This will be a brief talk to introduce the initiative and its goals.

32 UMU -- A unified tool and database for easily running your games outside of Steam¶

Last year's summit presented an opportunity for a lot of the major gaming on Linux developers to get together in one place and juggle ideas on how we can make gaming better on Linux. Ultimately we all had a general agreement that having a tool that can run cross-platform like Valve does, as well as a unified place for known game fixes to be used and shared would benefit everyone. From that opportunity spawned "Open Wine Components" -- our group, and we put together UMU.

What is UMU?

UMU-Launcher is a CLI tool that utilizes Valve's pressure-vessel system and runtime environment alongside proton to run non-steam games outside of steam just like steam does.

UMU-Database is an online database built together by members of various projects (Heroic, Lutris, Bottles, and more) assigning IDs for non-steam games, so that games all receive the same fixes no matter what launcher is being used as long as that launcher uses UMU-Launcher as the backend. The database is also searchable online via website and able to be queried for information via API end points/access points. The website source is also available in github in case any user wishes to self-host their own copy.

UMU-Protonfixes is a collection of game fixes -- things such as winetricks, dll overrides, exe overrides, registry entriees, and soon that can be applied to games when run in GE-Proton or UMU-Proton (or any version of proton that integrates UMU and Protonfixes into it).

The short gist of it is that umu-launcher is to gaming outside of steam what proton + pressure-vessel is to gaming inside steam.

33 Re-inventing distroless with Chiselled Ubuntu containers¶

Building Docker images is an easy and accessible practice, however, perfecting them is still an art that is challenging to master. In pursuit of the smallest, most secure and yet functional container images, developers face themselves with distroless practices that usually involve complex tooling, deep distro knowledge and error-prone trimming strategies. In fact, such practices often neglect the use of package managers, contributing to a security abyss, as most vulnerability scanners rely on package manager metadata to detect the software components within the container image.

Chisel introduces a novel pattern for building distroless-like container images from the ground up. It is a self-contained tool that cuts Ubuntu packages into a minimal filesystem, from scratch. Unlike a typical package manager, Chisel works with package “slices”, i.e. predefined subsets of existing packages that have been designed to compartmentalize functionality and leave out contents that are not required for the container application to run.

The result is a minimal, yet functional slice of an Ubuntu filesystem, with a reduced attack surface. There is no need to repackage or manipulate one’s application dependencies, meaning that whatever applications already work today with Ubuntu, will still work with Chiselled Ubuntu.

In this talk, we’ll cover the fundamentals of Chisel and demonstrate how easy it is for anyone to design and build their own minimal and secure container image.

34 Building secure and minimalistic Docker images for Data and ML with Rockcraft¶

Abstract
Embark with us on a journey to the new era of container images. Learn about “rocks” and why there are enhanced versions of traditional Docker images, and explore how to use the tools in the rocks ecosystem.

We will kick off by introducing the concept of chiselled images—lean, minimalistic container images derived from Ubuntu LTS images. You’ll get hands-on experience with Chisel, learning to trim down Debian packages to include only essential binaries and libraries. With these chiselled slices, you will craft your own data and ML rocks using a straightforward YAML format.

Throughout the workshop, we will guide you step-by-step, ensuring you understand how to use Rockcraft’s features to build and manage your rocks. You will also compare your rock images with other popular counterpart images from public registries, seeing firsthand the benefits of this streamlined approach.

By the end of the session, you’ll not only have created a couple of functional container images but also tested them with some fun applications. Whether you’re new to containerization or an experienced developer, this workshop will equip you with the skills to create secure, efficient, and maintainable container images. The workshop includes a couple of live exercises where you will build Data and ML rock images.

What are you going to learn in this workshop
- What is a rock and how does it differ from a Docker image
- The rock toolkit: Rockcraft, Chisel, Skopeo, etc
- How to cut slices from debian packages using Chisel
- How to declare your rock and pack it with Rockcraft
- Exercise 1: create a rock for a data container
- Exercise 2: create a rock for an ML container

What to expect

The workshop will be an interactive session. Participants are expected to bring their laptops with them. People will be paired into groups of 2-4 persons to divide the workload among themselves while experimenting the different parts of the exercises.

Minimum requirements
The workshop is designed to accommodate participants with diverse skill levels. Nonetheless, to make the most of this workshop and be able to engage with the exercises, you should:

• have an Ubuntu workstation or VM (a recent version is recommended, preferrably 24.04),
• be comfortable around a Linux terminal,
• have a basic understanding of shell scripting,
• be familiar with deb packages and snaps.

37 Miriway: Worlds of Wayland¶

"Miri" (the plural of mir) derives from the Russian for "world"; and "way" is for Wayland a protocol used by graphical shells (not the craftsman in European folklore).

Together these make Miriway: an easy way to leverage the Mir compositor engine to build Wayland based desktop environments.

There are many components to a desktop environments: backgrounds, panels, launchers, onscreen keyboards, notifications, etc. Miriway provides a Wayland compositor (which handles the display, input and window management) leaving the rest to be configured.

This talk describes the configuration options that Miriway offers and work through building a full desktop environment by incorporating components from one of the Fedora Spins.

43 Watt-Wiser: Measuring Software Energy Consumption¶

Software has a huge impact on the energy consumption of the hardware running it, but this impact has historically been difficult to measure without significant expertise and extra monitoring hardware. Now with the rise of AI and other GPU-heavy workloads, the energy consumption of computing is more important to understand than ever, but the tools for doing so are frequently hard to find, hard to use, and unable to generate a holistic picture of system energy consumption (missing crucial data like GPU energy consumption).

In an effort to enable visibility into software's energy consumption, I wrote Watt-Wiser, a GUI measurement suite for monitoring software energy consumption using sensors already built into the hardware and surfacing that to the end user. It's like your System Monitor application, but for energy.

This talk will cover:

• why we should measure energy consumption,
• how watt-wiser measures energy consumption,
• how to use watt-wiser on your own applications (for end-users), and
• how to benchmark your application energy use (for developers).
