linux: introduce io_uring support by bnoordhuis · Pull Request #3952 · libuv/libuv
Add io_uring support for several asynchronous file operations:
read, write
fsync, fdatasync
stat, fstat, lstat
io_uring is used when the kernel is new enough, otherwise libuv simply

A Cryptographic Near Miss
A recent issue in scalar multiplication makes for a good case study of how unsafe interfaces, undocumented assumptions, and time lead to vulnerabilities.

Servo 项目计划迁移到 Layout 2020
2023-04-14 14:01:00 by 火星超人
Servo 项目计划迁移到布局引擎 Layout 2020。Servo 是用 Rust 语言开发的实验性浏览器引擎项目，最初由 Mozilla 发起，2020 年 Mozilla 大裁员期间裁掉了 Servo 引擎团队，Servo 的开发此后陷入了停滞。Servo 项目后来找到 Linux 基金会托管，寻求为其它项目提供一个高性能的、安全的、可嵌入的模块化渲染引擎。过去几个月，项目的开发再次活跃。本周四，官方博客表示计划迁移到 Layout 2020 引擎。Servo 项目目前有两个布局引擎——Layout 2013 和 Layout 2020，顾名思义，其开发分别始于 2013 年和 2020 年，其中 Layout 2020 设计弥补 Layout 2013 的多个不足之处，开发者表示他们认为 Layout 2020 是项目继续前进的最佳布局引擎，计划不久之后迁移到该引擎。
