Chromium on Wayland Desktop (BlinkOn 7)

Igalia

Igalia is working on enabling Chromium to run natively on Wayland-based Linux systems by improving the Ozone/Wayland implementation. There are ongoing discussions around implementing external window mode in Ozone to allow Chromium windows to be separate from the host desktop, as well as splitting the UI and GPU components into separate processes as in ChromeOS. Igalia is focused on changing the Mus demo to support external window mode and getting Chromium to launch in this mode on Linux. Further work is also needed on desktop integration and using Mojo for inter-process communication in Ozone/Wayland.

Migrating python.org to buildbot 9 and python 3

Craig Rodrigues

Craig Rodrigues presented on migrating Python.org's build system from Buildbot 8 to Buildbot 9 and from Python 2 to Python 3. Buildbot is open source build automation software used by Python.org to build and test Python (CPython). The migration involved porting Buildbot and its dependencies like Twisted to be compatible with Python 3, porting Python.org's Buildbot configuration, and working with an ops team to complete the migration. This updated Python.org's infrastructure to a newer, actively supported version of Buildbot that enables new features and works with both Python 2 and Python 3.

Git is a distributed version control system (DVCS) created by Linus Torvalds in 2005 as an alternative to BitKeeper after its free-of-charge status was revoked for Linux kernel developers. Unlike typical SCMs that track file changes, Git treats each commit as a full snapshot of the project and only stores file differences between commits. This makes Git operations like branching and merging very fast and efficient. Git allows developers to work offline and each local repository contains the full project history. GitHub is a popular hosting service for Git repositories that allows for collaboration and code review. While Git can be used as a valid SVN client, it is best to avoid rewriting history when using Git with SVN to prevent issues with other team

Config management for_kubernetes: GitOps + Helm (CfgMgmtCamp 2020)

Tomasz Tarczyński

Presented at: Config Management Camp, Ghent, 2020-02 Kubernetes provides a declarative API, so you can describe the desired state of the system. And then it is the role of the control plane to operate the cluster (make the actual state match the desired state). But we still need config mgmt for API objects to the point when they are applied to the cluster. Helm helps to organize these configs into charts, template them, and manage releases. And GitOps lets you use a git repo as a single source of truth for the desired state of the whole system. Then all changes to this state are delivered as git commits instead of using kubectl apply or helm upgrade. In this talk I will introduce the GitOps model for operating cloud native environments and give a short demo. In this talk I show two CNCF projects: - Flux CD: https://fluxcd.io/ - Helm: https://helm.sh/

Sustainable Futures: Funding the Web Ecosystem

Igalia

We work and live in the modern world. Surely such an integral piece of our day-to-day life is being built and maintained in a way that ensures it will last? Unfortunately this isn’t the case. The current system funding access to the web is fragile, fractured and unsustainable. In this talk, I’ll give an overview of the current state of things, how we currently fund the web, why this is a problem, and possible ways to fix this so that access to information remains stable and sustainable for future generations to come.

A Year of the Servo Reboot: Where Are We Now?

Igalia

Created by Mozilla Research in 2012 and now part of Linux Foundation Europe, the Servo project is an experimental rendering engine written in Rust. It combines memory safety and concurrency to create an independent, modular, and embeddable rendering engine that adheres to web standards. Stewardship of Servo moved from Mozilla Research to the Linux Foundation in 2020, where its mission remains unchanged. After some slow years, in 2023 there has been renewed activity on the project, with a roadmap now focused on improving the engine’s CSS 2 conformance, exploring Android support, and making Servo a practical embeddable rendering engine. In this presentation, Rakhi Sharma reviews the status of the project, our recent developments in 2023, our collaboration with Tauri to make Servo an easy-to-use embeddable rendering engine, and our plans for the future to make Servo an alternative web rendering engine for the embedded devices industry.

Building End-user Applications on Embedded Devices with WPE

Igalia

The Web engine is the most important component of a Web Browser, enabling developers to harness the power of the Web Platform to build their applications. However, Web Browsers are not the only type of applications that can be built with Web Engines, which can also be used to develop other types of applications using the same Web-based technologies, but for a different type of use cases other than "browsing the Web". These use cases can cover a wide range of situations outside of the traditional desktop or mobile environments, such as the ones embedded systems are usually used for (e.g. set-top-boxes, smart home appliances, GPS navigation devices, or in-car/in-flight infotainment systems, to name a few). And in those situations it is very common to be running on boards with SoCs and a particular set of HW capabilities that make it crucial for the Web Engine to be able to tightly integrate with them. In this session we will focus on how WPE, a fully Open Source port of the WebKit Web engine for Linux-based embedded devices, can be used to adapt to the different challenges that embedded devices pose to develop end-user applications, using the power of the Web Platform underneath.

Raspberry Pi 5: Challenges and Solutions in Bringing up an OpenGL/Vulkan Driv...

Igalia

The Raspberry Pi 5 was announced on October 2023. This new version of the popular embedded device comes with a new iteration of Broadcom’s VideoCore GPU platform, and was released with a fully open source driver stack, developed by Igalia. The presentation will discuss some of the major changes required to support this new Video Core iteration, the challenges we faced in the process and the solutions we provided in order to deliver conformant OpenGL ES and Vulkan drivers. The talk will also cover the next steps for the open source Raspberry Pi 5 graphics stack.

Automated Testing for Web-based Systems on Embedded Devices

Igalia

Every day, embedded devices are becoming more powerful and capable of running more elaborate applications. Among these applications are Web-based ones, enabling to leverage features from the Web APIs to the embedded context, either through a generic browser running a traditional Web application or through a customized Web engine tightly integrated within the system. But such capabilities usually bring new challenges, like testing user interactions with the application using the embedded device's specific I/O methods, such as gestures, or inspecting Web application internals with JavaScript. In this context, using a browser automation framework such as WebDriver, which is a W3C standard supported by WebKit Web engine, allows testing Web-based applications on such devices as if the user were actually using it, alongside running custom JS code. In this session, we will cover why we need browser automation for testing on certain types of embedded devices, with a focus on WebDriver as the proposed tool to achieve that goal. We will also discuss WebDriver's main features and limitations, as well as other possible approaches and frameworks that could be considered for this kind of task.

Embedding WPE WebKit - from Bring-up to Maintenance

Igalia

Embedded devices have become powerful enough to run Web content a decade ago, and any modern SoC that can run Linux and includes a GPU is a potential candidate to hide a Web engine under the surface. How did it made it there? Does it only show Web content? What else can it do? The talk will cover bring-up tips to build and get WPE WebKit working on your custom embedded device and make your own simple Web browser, as well as the best practices for keeping the system up to date. No less important is integration with the rest of the system: this session will detail the possibilities that WebKit brings to the table, including how to add new JavaScript APIs which call into native code to provide tight, performant access to platform functionality.

Optimizing Scheduler for Linux Gaming.pdf

Igalia

This talk dives into how the scheduler impacts your gameplay on Linux and unveils our journey to smoother gameplay. How does task scheduling impact Linux gaming? Suboptimal task scheduling can cause stuttering while playing games on the Steam Deck game console. First, we nail down the enemy. What exactly is "stuttering," and how can we measure its impact on your gameplay? Next, we extensively analyzed the characteristics of game tasks from the scheduler’s point of view. Characterizing task behavior in Linux gaming helps to understand why some schedulers create much stuttering and others create less and to unveil the secrets behind smooth vs. choppy performance. Lastly, we will share our progress on the optimized scheduler for reducing the stuttering problems in Linux gaming, especially Steam Deck. We implemented the scheduling policy based on sched_ext, a BPF-based extensible scheduling framework.

Running JS via WASM faster with JIT

Igalia

So, we are adding a backend for the SpiderMonkey’s codegen to enable JIT support for JavaScript running through Wasm. Sounds a bit cryptic so let’s divide it into parts. SpiderMonkey is a JavaScript engine which is used for running JavaScript inside the Firefox browser. SpiderMonkey is written in C++ and supports compilation into the Wasm module, see live demo - https://mozilla-spidermonkey.github.io/sm-wasi-demo/. However, SpiderMonkey compiled into the Wasm module supports execution of JavaScript only in the interpreter-only mode and it doesn’t support just-in-time compilation because there is no Wasm backend for that. There are backends for Arm, X86, X64 etc but there is none for Wasm. Why do we want to add support for JIT? Well, because we want speed. Right now there is no solution to run JS scripts via Wasm fast, there are only interpreters. Why does JIT improve performance? The reasons are the same for why an interpreter is slower than a compiler - because it eliminates the interpreter loop, uses a more efficient ABI and, more importantly, it can specialize polymorphic operations in JavaScript. So, we not only enable the JIT tier in SpiderMonkey for Wasm but we also provide support for inline caches. Inline caches is a mechanism for specializing the behavior of particular operations like plus or a call to specific arguments provided at runtime. With all that we can generate Wasm modules on the fly, instantiate them, and link them to provide from ~2x to ~11x speedup over the interpreter. In the talks we will cover how the whole scheme works with SpiderMonkey: 1. How to link modules on the fly into SpiderMonkey.wasm 2. How to add an exotic Wasm backend into SpiderMonkey’s supported backend line - X64, X86, Arm, Wasm 3. How to use the whole solution in the cloud instead of QuickJS 4. How to get a speedup of your JS over wasm with test data. Wasm I/O 2024 14 - 15 Mar, 2024 Barcelona https://2024.wasmio.tech/

To crash or not to crash: if you do, at least recover fast!

Igalia

What could be possibly worse that an almost unbeatable boss in a game or a tough maze that consume hours of gameplay with not much progress? How about a Linux kernel crash that makes you lose all the game progress with no apparent reason or feedback? Though rare, it is a real possibility that would make gamers quite annoyed, given that Linux is used more and more as a platform for playing games. Some technologies are available to collect logs and feedback the user in case such disastrous events happen, mostly related with kernel crashes handling mechanisms. The main ones available are kdump and pstore, but still there are work to be done in this area... In this talk we're going to present the basics about kernel crash handling, like how a kernel panic might happen, how to deal with that (with an overall discussion about kdump and pstore techs) and the kdumpst tool, developed specially to deal with this situation on Steam Deck (and generically on Arch Linux); also we're gonna discuss some missing pieces / ideas to make it even less likely gamers need to complain that their device just got hang for no reason!

2023 in Chimera Linux

Igalia

Chimera Linux is a novel Linux distribution built around FreeBSD core tools and the LLVM toolchain. Since its initial launch in 2021, it has made a lot of progress and is now in alpha stage. The system can be deployed on a wide array of hardware and many people are using it as their desktop system; it works on x86_64, AArch64, POWER (little and big endian) as well as RISC-V and by now comes with thousands of packages. While trying to be practical, Chimera is also highly hardened, partly thanks to the LLVM toolchain, rendering it immune to various security issues other distros are vulnerable to. It has transparent and robust infrastructure, ensuring smooth deployment of packages. We are also developing various new tooling that the whole ecosystem can benefit from, including the Turnstile session tracker. Service management is based around Dinit, a modern, supervising system; we maintain and create a variety of tooling around it, trying to break the existing status quo with systemd, while abandoning legacy approaches. 2023 has seen several major milestones, so I will focus on these, while also giving a short overview so that people unfamiliar with the system don't feel lost. I will also explain how our work benefits the entire Linux ecosystem, as well as beyond.

Building a Linux distro with LLVM

Igalia

For the last 3 years, I've been building a complete Linux distribution, Chimera Linux (https://chimera-linux.org) using solely LLVM as its system toolchain - that means Clang, compiler-rt, and libc++, alongside its other tooling. Right now, it is a complete desktop system that is already used by many, with a familiar GNOME interface and thousands of packages, targeting 5 CPU architectures. In this talk I would like to focus on my experiences using the toolchain, what obstacles got in the way, how I dealt with them, the issues that are still left and I would like to see addressed, the many benefits using LLVM gave the project, and overall give the audience an insight into practical deployment of LLVM in a project where it isn't simply a drop-in alternative to GCC.

Delegated Compositing - Utilizing Wayland Protocols for Chromium on ChromeOS

Igalia

This talk will cover our experience in utilizing Wayland subsurfaces and implementing delegated compositing for Chromium on ChromeOS. Several concepts will be covered - from overlay making decision in Chromium/Viz to design and implementation of custom Wayland protocols, which were required to pass frame data as overlays via Wayland and reconstruct that frame on the Wayland server side.

MessageFormat: The future of i18n on the web

Igalia

Internationalization in JavaScript and on the web platform is very complicated, but also vastly important for us developers in order to build accessible and intelligible interfaces. Thankfully, Unicode Consortium's MessageFormat working group and TC39 have been hard at work standardizing the next generation of i18n tooling that aims to unify analogous non-standard tools in use today while approaching this problem from a fresh perspective. Join me along this tour of i18n in JavaScript, discover some of the newest additions to the toolkit and learn about the ongoing MessageFormat proposal and how it aims to radically improve the developer experience.

Mutation Testing for Task-Oriented Chatbots

Pablo Gómez Abajo

Conversational agents, or chatbots, are increasingly used to access all sorts of services using natural language. While open-domain chatbots - like ChatGPT - can converse on any topic, task-oriented chatbots - the focus of this paper - are designed for specific tasks, like booking a flight, obtaining customer support, or setting an appointment. Like any other software, task-oriented chatbots need to be properly tested, usually by defining and executing test scenarios (i.e., sequences of user-chatbot interactions). However, there is currently a lack of methods to quantify the completeness and strength of such test scenarios, which can lead to low-quality tests, and hence to buggy chatbots. To fill this gap, we propose adapting mutation testing (MuT) for task-oriented chatbots. To this end, we introduce a set of mutation operators that emulate faults in chatbot designs, an architecture that enables MuT on chatbots built using heterogeneous technologies, and a practical realisation as an Eclipse plugin. Moreover, we evaluate the applicability, effectiveness and efficiency of our approach on open-source chatbots, with promising results.

Currently, there is a growing demand for standardization and interoperability in energy data and modeling. Open source standards and specifications within the energy sector can also alleviate challenges associated with data fragmentation, transparency, and accessibility. At the same time, it is crucial to consider privacy and security concerns throughout the development of open source platforms. This webinar will delve into the motivations behind establishing LF Energy’s Carbon Data Specification Consortium. It will provide an overview of the draft specifications and the ongoing progress made by the respective working groups. Three primary specifications will be discussed: -Discovery and client registration, emphasizing transparent processes and secure and private access -Customer data, centering around customer tariffs, bills, energy usage, and full consumption disclosure -Power systems data, focusing on grid data, inclusive of transmission and distribution networks, generation, intergrid power flows, and market settlement data

Introduction of Cybersecurity with OSS at Code Europe 2024

Hiroshi SHIBATA

I develop the Ruby programming language, RubyGems, and Bundler, which are package managers for Ruby. Today, I will introduce how to enhance the security of your application using open-source software (OSS) examples from Ruby and RubyGems. The first topic is CVE (Common Vulnerabilities and Exposures). I have published CVEs many times. But what exactly is a CVE? I'll provide a basic understanding of CVEs and explain how to detect and handle vulnerabilities in OSS. Next, let's discuss package managers. Package managers play a critical role in the OSS ecosystem. I'll explain how to manage library dependencies in your application. I'll share insights into how the Ruby and RubyGems core team works to keep our ecosystem safe. By the end of this talk, you'll have a better understanding of how to safeguard your code.

Apps Break Data

Ivo Velitchkov

How information systems are built or acquired puts information, which is what they should be about, in a secondary place. Our language adapted accordingly, and we no longer talk about information systems but applications. Applications evolved in a way to break data into diverse fragments, tightly coupled with applications and expensive to integrate. The result is technical debt, which is re-paid by taking even bigger "loans", resulting in an ever-increasing technical debt. Software engineering and procurement practices work in sync with market forces to maintain this trend. This talk demonstrates how natural this situation is. The question is: can something be done to reverse the trend?
