第三届中国Rust开发者大会 Building Linux Distribution from Scratch with Rust Speaker: Jia Xiaoyu CONTENTS Why choose rust? Using Rust and LFS build linux distro O2 What rkos brings us? Why do we choose by memory unsafety. 2. Security issues can happen not only in the kernel, but also in the whole system, which includes the kernel and the system software. Why do we choose rust? The number of vulnerabilities What rust-related things have happened in the kernel since the release of kernel 6.1? •Linux 6.1: Officially Adds Support for Rust in the Kernel • Kernel internals (kallsyms expansion for Rust symbols

DE组件 Windows Manager Input Method Launcher Panel (dock) Question: DE是否应该努力追求本身独立? 可以跑在更多发行版上 更多的受众，更多的反馈 但DE最终会与底层服务甚至特定版进行交互，完全独立很难走到完美。 造成更多的开发包袱 Linux不会被统一,所以DE最好还是拥有更好的内聚性。 但应该打包更多的系统在一起, 从更多的地方优化用户体验，无折腾。 基础文件系统 + 仓库 + DE + 软件商店(各种应用软件才是正常用户需要的 Systemd, upstart ...

Rust for Linux Miguel Ojeda Wedson Almeida Filho Alex Gaynor Rust for Linux aims to add Rust support to the Linux kernel. We believe Rust offers key improvements over C in this domain. We hope priority is to stabilize them (or to find alternatives): https://github.com/Rust-for-Linux/linux/issues/2 The kernel should build without RUSTC_BOOTSTRAP. The rest of this talk focuses on things that infer the name, and call __mutex_init. Language Library Modularization of core and alloc The kernel does not need a range of core/alloc features. Configuring them off is important for correctness

1 Linux 下 Makefile 的 automake 生成 全攻略 作为 Linux 下的程序开发人员，大家一定都遇到过 Makefile，用 make 命令来编译自己写 的程序确实是很方便。一般情况下，大家都是手工写一个简单 Makefile，如果要想写出一 个符合自由软件惯例的 Makefile 就不那么容易了。 在本文中，将给大家介绍如何使用 autoconf 和 automake 的 Makefile ， 这 样 就 可以 象 常 见 的 GNU 程 序 一 样 ，只 要 使 用 “./configure”，“make”，“make install”就可以把程序安装到 Linux 系统中去了。 这特别适合想做开放源代码软件的程序开发人员，又或如果你只是自己写些小的 Toy 程序， 那么这个文章对你也会有很大的帮助。 一、Makefile 介绍 Makefile 是 configure 依据 Makefile.in 来生成一个符合惯例的 Makefile。下面我们将详细介绍 Makefile 的 automake 生成方法。 二、使用的环境 本文所提到的程序是基于 Linux 发行版本：Fedora Core release 1，它包含了我们要用到 的 autoconf，automake。 三、从 Hello world 入手 我们从最常使用的例子程序 helloworld

notebook has exactly one interactive session connected to a kernel, which will execute code sent by the user and communicate back results. This kernel remains active if the web browser window is closed, and the web application to the same kernel. In the dashboard, notebooks with an active kernel have a Shutdown button next to them, whereas notebooks without an active kernel have a Delete button in its place Other clients may connect to the same kernel. When each kernel is started, the notebook server prints to the terminal a message like this: [NotebookApp] Kernel started: 87f7d2c0-13e3-43df-8bb8-1bd37aaf3373
