📰 AI Helped Uncover A "50-80x Improvement" For Linux's IO_uring
Linux block maintainer and IO_uring lead developer Jens Axboe recently was debugging some slowdowns in the AHCI/SCSI code with IO_uring usage. When turning to Claude AI to help in sorting through the issue, patches were devised that can deliver up to a "literally yield a 50-80x improvement on the io_uring side for idle systems." The code is on its way to the Linux kernel...

Linux from Scratch to drop System V versions
Linux From Scratch (LFS) 项目宣布将停止维护其 System V 版本,未来的版本将仅专注于 systemd。
做出这一决定主要有两个原因:
1. **工作量过大**:LFS 项目完全由志愿者维护,需要跟踪海量的上游软件包更新。为 System V 和 systemd 两个初始化系统分别检查和更新所有软件包,给编辑者带来了难以承受的负担。
2. **软件生态的推动**:像 GNOME 以及即将到来的 KDE Plasma 等主流桌面环境,越来越多地依赖 systemd 提供的特定功能,这些功能是 System V init 所不具备的。虽然可以转向 OpenRC 等其他初始化系统,但这依然无法解决持续维护的工作量问题。
项目负责人 Bruce Dubbs 在公告中表达了对这一决定的个人遗憾。他认为 LFS 的核心是帮助用户理解系统如何工作,而理解启动过程是其中重要的一环。System V init 的实现相对简洁(约22个C文件和一些脚本),而 systemd 则庞大复杂得多(约1678个C文件)。转向 systemd 虽然带来了更多功能,但也意味着会失去一些他认为重要的、用于教学理解的东西。
预计仅支持 systemd 的下一个主要版本 LFS 13.0 将于今年三月发布。

📰 Ubuntu Still Figuring Out A Plan For Dealing With California's Digital Age Assurance Act
The talk this week among open-source projects from Linux distributions to app stores like Flathub is how to deal with California's latest insanity: the Digital Age Assurance Act. California's AB 1043 state law is mandating that operating systems -- Linux included -- collect age information during account setup and exposing that age to eligible apps beginning on 1 January 2027.
