Wayland & Weston Compositor Ported To DragonFlyBSD
Wayland has been ported to DragonFlyBSD along with its Weston compositor!
In the past we've seen some minor experiments by BSD developers with Wayland/Weston, but for the most part all of the BSDs are still focused on X.Org Server support -- need I remind Phoronix readers that DRM/KMS support is in varying stages across the BSD distributions too as one of the support stepping stones. Just a few days ago I ran into the DragonFly Radeon kernel module failing to properly mode-set with a several year old (pre-GCN) graphics card while meanwhile FreeBSD's Radeon KMS port worked. It's still rather a mine field when it comes to open-source graphics acceleration and support on the BSDs while slowly but surely their catching up with the kernel code.

Over time, memory can become more and more fragmented on a system, making it difficult to find contiguous blocks of RAM to satisfy ongoing allocation requests. At certain times the running system may compact regions of memory together to free up larger blocks, but Vlastimil Babka recently pointed out that this wasn't done regularly enough to avoid latency problems for code that made larger memory requests.
