One of the contradictions of the modern open-source movement is that projects which respect user freedoms often rely on proprietary tools that do not: communities often turn to non-free software for code hosting, communication, and more. At Configuration Management Camp (CfgMgmtCamp) 2026, Jan Ainali spoke about the need for open-source projects to adopt open tools; he hoped to pe

There are many applications that need to be able to write multi-block chunks of data to disk with the assurance that the operation will either complete successfully or fail altogether — that the write will not be partially completed (or "torn"), in other words. For years, kernel developers have worked on providing atomic writes as a way of satisfying that need; see, for example, sessions from the Linux Storage, 文件系统, 内存管理, and BPF (LSFMM+BPF) Summit from ✨ 关键特性：

• atomic writes when directI/Ois in use

• the proposed writethrough behavior with immediate initiation of the requested operation

Toke Høiland-Jørgensen has posted an overview of how zero-copy networking works in the Linux内核.

Since the memory is being copied directly from userspace to the network device, the userspace application has to keep it around unmodified, until it has finished sending. The sendmsg() syscall itself is asynchronous, and will return without waiting for this. Instead, once the

Jujutsu is an increasingly popular Git-compatible 版本-control system. It has a focus on simplifying Git's conceptual model to produce a smoother, clearer command-line experience. Some people already have a preferred replacement for Git's usual command-line interface, though: Magit, an Emacs package for working with Git repositories that also tries to make the interface more discoverable. Now, a handful of pe

Matthew Garrett examines the factors that go into the decision about whether to install a firmware 更新 or not.

I trust my CPU vendor. I don't trust my CPU vendor because I want to, I trust my CPU vendor because I have no choice. I don't think it's likely that my CPU vendor has designed a CPU that identifies when I'm generating cryptographic keys and biases the RNG output so my
