Who doesn't know about ls, chmod or cp? Who isn't using it daily? Coreutils are critical components of any Unix. According to its Wikipedia page, the first versions of cp or chown have been released in November 1971. Almost all Linux distros are based on the GNU implementation.

Fast forward today, a community spawned to reimplement the coreutils in Rust. We are able to boot a Debian with it, build Firefox or LLVM, etc.

This presentation will explain why we are re-implementing the wheel. But also how we are doing it, share some of the corner cases we have been facing, why we are (sometime) faster, etc

We will also quickly mention the usage of Rust in the Linux kernel. With these two projects, we think that we will see more and more core piece of the Linux ecosystem in Rust.

Developed by a huge community of developers and users, Firefox is one of the biggest software ever created.

In every release, a crazy number of patches (~8000) lands into the code base. The changes can be C, C++, Java, Rust, Javascript, XML, HTML, CSS, etc.

In order to avoid regressions, over years, Mozilla created a number of tools, method and process to make sure the release in a good shape at release day.

This talk will present the various strategy deployed to reach the best quality possible. We will present a wide range of techniques like manual QA, automated tests, code coverage, static analysis, fuzzers, crash detection and managements, etc.

Mozilla Firefox is a Web Browser. The red panda just turned 10. For the last 4 years, we have been releasing a major release every 6 weeks. During this talk, we will explain how we have been able to reach this goal.

Releasing software is hard. Doing it every 6 weeks is harder, especially in an environment like a Web browser in which there are constant evolutions and changes. We will explain how we have been able to reach a high quality level on a software complex as an operating system while keeping frozen deadlines. We will present our workflow, our tools and our organization to reach these goals.

When starting to contribute to LLVM knowing the technical steps and especially the community habits can make the first (and upcoming) contribution a lot easier and the contribution process will become a more positive experience. This talk will discuss technical points such as your first patch for LLVM, how to get +w permissions, the various workflows, but also more soft skills such as 'how can I find a reviewer for my patch', 'should I review patches myself', or 'what is this the right strategy to add a larger feature to LLVM'?

The LLVM Project is a collection of modular and reusable compiler and toolchain technologies. Despite its name, LLVM has little to do with traditional virtual machines, though it does provide helpful libraries that can be used to build them. The name "LLVM" itself is not an acronym; it is the full name of the project.

LLVM began as a research project at the University of Illinois, with the goal of providing a modern, SSA-based compilation strategy capable of supporting both static and dynamic compilation of arbitrary programming languages. Since then, LLVM has grown to be an umbrella project consisting of a number of subprojects, many of which are being used in production by a wide variety of commercial and open source projects as well as being widely used in academic research. Code in the LLVM project is licensed under the "UIUC" BSD-Style license.

The LLVM dev-room gives room for open source projects to get to know LLVM and to present to a wider audience how they use LLVM themselves.

After extending Debian with two new kernels, Debian will soon be able to be built with a new free C, C++ and Objective-C compiler called Clang. Based on LLVM, this compiler is now close to gcc on many different aspects (performances, build time, level of support of C and C++). This talk will present the current status of a clang-build version of Debian, the next steps and evolutions.

Scilab has left Inria, a French public research institute to a corporation of 20 people and currently it is used in many different fields. The talk will present how this has been made possible in terms of code, documentation, processes, etc.
