Kernelnewbies are a community of people that improve or update their Kernels and of aspiring Linux kernel developers and more experienced developers willing to share their knowledge. We help each other learn how the Linux kernel works and occasionally discuss other operating system kernels.

A mailing list for coordinating ath5k development, for a first review of patches, and so on.

Linux kernel-janitors discussion, going through the Linux kernel source code, doing code reviews, fixing up unmaintained code and doing other cleanups and API conversions. It is a good start to kernel hacking.

Discussion surrounding the development of the MadWifi and ath5k wireless Ethernet device drivers.

IA64 development mailing list.

A mailing list about the Tux3 versioning filesystem.

Sparse, the semantic parser, provides a compiler frontend capable of parsing most of ANSI C as well as many GCC extensions, and a collection of sample compiler backends, including a static analyzer also called "sparse". Sparse provides a set of annotations designed to convey semantic information about types, such as what address space pointers point to, or what locks a function acquires or releases. Linus Torvalds started writing Sparse in 2003, initially targeting issues such as mixing pointers to user address space and pointers to kernel address space. As of 2006, Josh Triplett now maintains Sparse.

An informal project to get experienced developers to mentor new developers and coach them on the best ways to get their code ready for submission.

Git is the change-tracking tool used by the Linux kernel developers, originally written by Linus Torvalds. This mailing list is where git development happens.

The Linux USB mailing list.

Git commits to the 2.6 Linux kernel.

Linux Security Modules (LSM) development mailing list.

Linux input device development.

The original Linux kernel discussion forum, originally a mailing list it eventually became the newsgroup comp.os.linux. Our archive includes postings from 1991, 1992, and 1993. Originally described as:

"Linux_activists is a discussion archive of the mailing list about Linux, a free unix-like kernel for 386-AT computers, coming with full source code. It is meant for hackers/computer science students to use, learn and enjoy."

Discussion of technical topics for OpenBSD developers and advanced users. This is not a "tech support" forum. OpenBSD developers will often make patches to implement new features and other important changes available for public testing through this list.

OpenBSD bug reports as sent in via sendbug(1) and follow-up discussions.

This low volume list receives OpenBSD security advisories and pointers to security patches as they become available.

Development of multiprocessor support in OpenBSD.

DragonFly BSD commit messages since December of 2004.

Discussion about DragonFly BSD. We offer a complete archive of this mailing list since its creation in September of 2004.

Discussion about the DragonFly BSD kernel. Our archives of this mailing list start in October of 2003.

Discussion about the development of the Haiku kernel.
