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.

ALSA development mailing list.

UCARP allows a couple of hosts to share common virtual IP addresses in order to provide automatic failover. It is a portable userland implementation of the secure and patent-free Common Address Redundancy Protocol (CARP, OpenBSD’s alternative to the patents-bloated VRRP).

The OpenFabrics Alliance is currently developing a unified, open-source software stack for the two major RDMA fabric technologies -- InfiniBand and iWARP (also known as RDMA over Ethernet). OpenFabrics hosts the git repositories for the Linux InfiniBand subsystem.

This mailing list is dedicated to discussions and ideas pertaining to Tech Source's free-software-friendly graphics products. There is a great need in the Free Software and Open Source communities for graphics cards which have open specifications, and my employer, Tech Source, would like to meet those needs in a technically and economically feasible way.
