LLVM/Clang 3.3 Very Competitive To GCC 4.8

Benchmarks for sharing this weekend are looking at the performance of GCC 4.7, GCC 4.8, LLVM/Clang 3.2, and the latest LLVM/Clang 3.3 development code. How does the performance of the newly released GCC 4.8.0 compare to the yet-to-be-released LLVM/Clang 3.3? It's interesting.

Why Wayland & Weston Were Forked

Last week, Wayland/Weston was forked by a long-time contributor, Scott Moreau. The fork of the Wayland/Weston display server ended up becoming known as Northfield/Norwood, following disagreements within the Wayland development camp. Scott Moreau was ultimately banned from the Wayland mailing list and IRC channel, so he's written an exclusive, independent article for Phoronix to explain his actions and why he felt a fork of the Wayland display server protocol and the reference Weston compositor were necessary.
