📰 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... 🔗 Source: https://www.phoronix.com/news/AI-50-80x-IO-uring #linux#kernel

#UNIX#POSIX 问题：如何正确理解 Permission denied 和 Operation not permitted 之间的区别？ 答案: TL;DR: Permission denied: 老兄，你越界了，这个真不行。 Operation not premitted: 老兄，你在说什么鬼话？ Permission denied 通常用于表示明确的因为权限设置导致的拒绝。 Operation not premitted 通常用于表示因为设计原因所不被允许的操作。 不过在实际的开发中，有的人似乎并不care这些，因此你也会见到因为权限策略拒绝时返回的 Operation not premitted 错误。（例如SELinux）

Freedesktop.org now hosts the Filesystem Hierarchy Standard 文件系统层次结构标准（FHS）现已由Freedesktop.org托管和管理。FHS定义了POSIX操作系统如何组织系统和用户数据，被Linux、BSD及其他遵循POSIX规范的系统广泛采用。这一变动结束了此前关于FHS未来发展的讨论。 新规范页面可在此查看：https://specifications.freedesktop.org/fhs/latest/ #Linux#POSIX#文件系统标准#开源 #AIGC Read more

It uses a master server to manage volumes on volume servers, which handle file data and metadata, enabling very fast file access with minimal disk reads. It supports features like replication, erasure coding, cloud integration for elastic storage, and compatibility with many metadata stores and APIs including Amazon S3. This means you get efficient, cost-effective storage with fast access, easy scaling, and flexible deployment options for large-scale file storage needs. https://github.com/seaweedfs/seaweedfs
