By Joaquim Rocha. YouTube, Shoutcast, Last.fm or Jamendo are just some examples of the number of existing services offering media content nowadays. Users are now getting used to having these services available also from their usual applications. Unfortunately, to integrating these services in an application developers need to learn new technologies, with different APIs and protocols which means they end up writing specific solutions and replicating a lot of work. Grilo was created to solve this problem by providing a framework that abstracts the way to access media services and hides their specifications from developers. This minimizes the effort to integrate such services in applications letting the developers focus on their applications rather than in the services. In this talk, I will introduce Grilo, the problem it solves, the services it integrates so far, and give an overview of how to use Grilo in applications. If time allows, I will also show how a Grilo plugin looks like.

By Joaquim Rocha. Even with all the existing alternatives, nowadays a lot of information is still printed on paper. From historical documents to places that only recently started to use digital documents in their usual workflow, this information is conditioned by the limitations of paper: hard to index and search, risk of deterioration, ecological implications, etc. Fortunately the state of the art Optical Character Recognition engines, including Free Software solutions, have high success rates in converting printed text into a digital format. However, these command-line tools only convert graphics in text, usually not taking into consideration the layout of the documents analyzed. This means that a regular page with a mixture of text in columns and eventual graphics will be read as if it was only text. There are some solutions that do take into account the structure of the documents besides performing OCR but these are proprietary and commercial and usually do not a version for Linux. OCRFeeder attempts to solve this problem. It automatically tries to outline the structure of the document (using its own algorithm), detect between graphics and text and performs OCR. Its main exportation format is ODT but it can also export to HTML and save or load projects. It is also possible to use different system-wide OCR engines in the same document and manually override any automatic action (for example, to correct its results, etc.). OCRFeeder is published under GPL v3 and was thought to be used mainly in the GNOME desktop environment and it's developed in its infrastructure. It stands as the only Free Software solution to provide a complete and easy to use graphical user interface application to convert printed documents. When used with the Orca screen reader, OCRFeeder is also a useful application for the visually impaired since it enables a printed document to be converted and read by Orca. Thus, during 2010, the main focus of OCRFeeder's development was the improvement of its accessibility Currently, the main features of OCRFeeder are: - Detection of the contents in a document's page; - Classification of those contents (graphics or text); - Deskew of images; - Importation from a scanner device or PDF; - Exportation to ODT or HTML; - Manual edition of any results. - Save and load projects. In this presentation I will explain how OCRFeeder's contents detection algorithm works, how a usual workflow to convert a document should be and give an overview of the main features of OCRFeeder with a demo.

By Joaquim Rocha. Currently there are still a lot of documents still stored in paper format and this presents some problems related to preservation, flexibility and even ecology. With the current Free Software OCR engines it is possible to get a good accuracy rate when converting printed text to digital format but these engines only perform that basic conversion and know nothing about a document's structure and elements. OCRFeeder presents itself as an easy to use solution implemented for GNOME that performs automatic content detection in pages, allows manual correction and uses the system-wide OCR engines to convert the text. It allows to export the documents in various formats such as ODT, HTML or PDF. This project stands as the most complete Free Software solution for converting printed documents to digital formats and competes with the proprietary alternatives.

By Joaquim Rocha. OCRFeeder is a document layout analysis and optical character recognition system that I wrote for my Master's Thesis project. Like it says on its website, given the images it will automatically outline its contents, distinguish between what's graphics and text and perform OCR over the latter. It generates multiple formats being its main one ODT. I think this is currently the most complete and user friendly OCR application for GNU/Linux out there and, of course, I wrote it to be used mainly with GNOME, featuring a GUI written in PyGTK and respecting, as far as I could, the GNOME User Interface Guidelines. I would like to present how the application works on the inside, for example the page segmentation algorithm I created for it, etc. I think this would be interest for the GNOME community and general attendants of the GNOME Dev room at FOSDEM.

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.

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.

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.

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.

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.

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/

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!

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.

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.
