bonch writes “Apple’s Grand Central Dispatch, which was recently open sourced, has been ported to FreeBSD and is planned to be included by default in FreeBSD 8.1. Also known as libdispatch, the API allows the use of function-based callbacks but will also support blocks if built using FreeBSD’s clang compiler package. There’s already discussion of modifying BSD’s system tools to use the new technology.” The port was originally unveiled last month at the 2009 Developer Summit in Cambridge. Slides from that presentation are available via the Dev Summit wiki.

Reader tail.man points out this press release from Debian which says that the port of the Debian system to the FreeBSD kernel will be given equal footing alongside Debian’s several other release ports, starting with the release of Squeeze. Excerpting from this release: “The kFreeBSD architectures for the AMD64/Intel EM64T and i386 processor architectures are now release architectures. Severe bugs on these architectures will be considered release critical the same way as bugs on other architectures like armel or i386 are. If a particular package does not build or work properly on such an architecture this problem is considered release-critical.Debian’s main motivation for the inclusion of the FreeBSD kernel into the official release process is the opportunity to offer to its users a broader choice of kernels and also include a kernel that provides features such as jails, the OpenBSD Packet Filter and support for NDIS drivers in the mainline kernel with full support.”

An anonymous reader writes “Phoronix has brought benchmarks comparing the FreeBSD 8.0-RC and Ubuntu 9.10 Alpha 6 operating systems. FreeBSD rather ends up taking a wallop to Ubuntu Linux, but there are a few areas where FreeBSD 8 ran well. They also posted benchmarks comparing this near-final FreeBSD 8.0 build to that of FreeBSD 7.2 to show performance improvements there but with a few regressions.”

The first of the Release Candidates for the FreeBSD-8.0 release cycle is now available. ISO images for Tier-1 architectures and a memory stick image for amd64/i386 are now available on most of the FreeBSD mirror sites.

electrostaticcarrot writes “DragonFly — that fourth major BSD — has had its 2.4 release. The ‘most invasive change’ is the addition and usage of a DevFS for /dev; building on this, drives are now also recognized by serial number (along with /etc/devtab for aliases) as listed in /dev/serno. This is also the first release with a x86-64 ISO, stable but with limited pkgsrc support. Other larger changes include a ported and feature-extended (with full hotplug and port multiplier support) AHCI driver (and SILI driver based on it) originally taken from OpenBSD, major NFS changes, and HAMMER updates. A pkgsrc GIT mirror has also been set up and put in use to make future pkgsrc updates quicker and smoother. Here are two of the mirrors.”

The fourth and last of the BETA builds for the FreeBSD-8.0 release cycle is now available. ISO images for Tier-1 architectures and a memory stick image for amd64/i386 are now available on most of the FreeBSD mirror sites.

Adam Dunkels writes “Inspired by the Twitter-sized program that crashes Mac OS X, I just wrote a really, really rudimentary IP stack called twIP, small enough to fit in a Twitter tweet. Although twIP is very far away from a real IP stack, it can do the first task of any IP stack: respond to pings. The entire source code can be found in this 128-character-long tweet. For those who are interested in low-level network programming, a code walkthrough with instructions on how to run the code under FreeBSD is available here. The FAQ: Q: why? A: for fun.”
