  TriBUG: Overview of BSD   (Site not responding. Last check: 2007-10-09)
Organizationally, BSD, in all its forms past and present, has been and is driven by a set of design goals established by a team of core individuals and with those design goals kept in mind while striving for improvement.
BSD, on the other hand, is a complete system with not only its own kernel but also its own libraries, utilities, documentation, and so forth.
BSD also continues to evolve, most recently with SMP development, the soft-updates implementation in FFS, and Kirk McKusick's development of UFS2, which has now been integrated into at least the current branches of most of the BSDs.

 Darwin (operating system) - Wikipedia, the free encyclopedia
Darwin is built around XNU, a hybrid kernel that combines the Mach 3 microkernel, various elements of FreeBSD 5 (including the process model, network stack, and virtual file system), and an object-oriented device driver API called I/O Kit.
Darwin does not include many of the defining elements of Mac OS X, such as the Carbon and Cocoa APIs or the Quartz Compositor and Aqua user interface, and thus cannot run Mac applications.
This is a table of Darwin releases with their dates of release and their corresponding Mac OS X releases.

 Darwin FAQ   (Site not responding. Last check: 2007-10-09)
Darwin is a version of the BSD UNIX operating system that offers advanced networking, services such as the Apache web server, and support for both Macintosh and UNIX file systems.
Apple's releases of Darwin will focus primarily on supporting Mac OS X. However, we also expect that other people will use Darwin to customize Mac OS X to meet their specific needs, adding platforms or features that are not a priority for Apple.
BSD has always had a rich academic developer community behind it, and while much of the original BSD UNIX was not free, its source code was available to anyone who obtained a license for it.

 BSD to leapfrog Linux? - TechUpdate - ZDNet   (Site not responding. Last check: 2007-10-09)
BSD is likely to rival Linux very soon in total number of users, and the BSD community is primping for center stage.
Much of the excitement revolves around Darwin, "the fifth BSD." Darwin is published by Apple and available for download from PublicSource.Apple.Com under the Apple Public Source License.
Darwin 1.2 bodes well for a timely MacOS X delivery schedule, and the BSD community -- long the free Unix-like OS world's forgotten stepchildren in the face of Linux superstardom -- are clearly relishing the chance to battle both Linux and Microsoft on a global OS scale.

 Darwin, Mach, BSD. Who does what   (Site not responding. Last check: 2007-10-09)
Darwin, which comprises the underpinnings for Mac OS X, is "Mach", "BSD", and "IOKit".
IOKit is the device driver support component of Darwin; BSD is the primary "OS"; and Mach is used to provide memory management, process/task/thread support, and messaging.
Mach is not "the OS"; mach mechanisms are used in support of the BSD OS component; Darwin is a monolithic kernel.

 Differentiating Among BSD Distros
Darwin, the kernel on which Mac OS X is based, is itself based on the FreeBSD code with a custom Mac kernel in place of the standard BSD kernel.
Darwin's main focus is to provide the base on which the rest of the Mac OS X environment runs.
The Darwin core is an open source project, with Apple and members of the Darwin community enhancing the Darwin code and extending the operation and functionality of the system.

 Daemon News : Introduction to Darwin
Darwin is also a BSD that works on Macintosh hardware, and is the only reasonable choice for some of the newer Macintosh machines.
However, the most interesting reason to work on Darwin is that Darwin maintains BSD compatibility, but takes a different approach at problems than the traditional BSDs.
Darwin is a BSD with radical deviations from the traditional design.

 Darwin BSD - Wikipedia, la enciclopedia libre
Darwin es el sistema que subyace en Mac OS X, cuya primera versión final salió en el 2001 para funcionar en los ordenadores Macintosh.
Integra el microkernel Mach y servicios de sistema operativo de tipo UNIX basados en BSD 4.4 (en particular FreeBSD) que proporcionan una estabilidad y un rendimiento mayor que el de versiones anteriores de Mac OS.
Darwin proporciona al Mac OS X prestaciones modernas, como la memoria protegida, la multitarea por desalojo o expulsiva, la gestión avanzada de memoria y el multiproceso simétrico.

 The Strength of BSD
A hot topic in the world of computers is Linux, but the BSD's have been around for longer, and some administrators would suggest that the BSD's are the only way to go for "high-hit" and high stability environments.
More importantly to the readers of Applelust, the BSD lineage has particular importance to the development of Mac OS X as it is from this lineage that first NeXT and now Apple take their cue.
This version of BSD is geared towards high performance, mission critical server environments where commercial support is required.

 GNU-Darwin becomes 1.0!   (Site not responding. Last check: 2007-10-09)
Darwin is at the center of capitalization for the whole Apple community, which is a great space for innovation and growth, but we should not discard the value of software freedom for mere technical merit, monetary gain, or convenience, which are secondary values.
Darwin has had a major revision since that time, but I don't think that there has been very much change in computational speed relative to Linux.
Until Darwin is freed, I'd say that kernel-level parallelization is better pursued with Hurd or with a free BSD OS.

 O'Reilly Network -- What Is Darwin (and How It Powers Mac OS X)
Darwin's BSD-based extensible network protocol stack gives rise to OS X features such as Bonjour, a zero-configuration networking implementation that eliminates just about all of the hassles that are normally associated with networking.
Apple releases a new version of Darwin on their open source site for each major update to OS X, and it's not long after Apple's release that the folks at OpenDarwin.org provide a corresponding build of OpenDarwin.
Little did they know that Darwin had been leading the way by compiling for x86 alongside of Mac OS X since the conception of OS X--a practice that no doubt provides a significant boost to the overall effort.

 21st-MacOS X
The Mach kernel and BSD (MacOS X uses the FreeBSD 3.2 kernel layered on Mach, while NetBSD is utilized for the user space, according to Probhakar) and the Mach and FreeBSD kernels both live in the same address space.
Darwin has not passed formal POSIX compliance tests, and at the current time, Apple says it has no plans for submitting its new UNIX OS for such certification.
Of course, the $64,000 Mac OS X question is why Darwin uses Mach (originally developed at Carnegie Mellon University), and not the latest BSD kernel.

 BSD News
I personally like Darwin and I think it is wonderful that there is a BSD product that will be able to get the attention of "normal" desktop computer users and show people what BSD can do.
Darwin proper has in it a significant portion of BSD but some equally significant portions are not and those parts are just as open, i.e.
Darwin is great and I'm glad that BSD is there for people to use so freely, but we've got to think before giving so much credit to Apple.

 BSD to leapfrog Linux? | Tech News on ZDNet
For example, leading online BSD publication DaemonNews will launch a dead trees version on Jan 15 of 2001, while each of the five BSD flavors will make or has already made a major new release within the current 30-day window.
The on-schedule release of Darwin 1.2 bodes well for a timely MacOS X delivery schedule, and the BSD community -- long the free Unix-like OS world's forgotten stepchildren in the face of Linux superstardom -- are clearly relishing the chance to battle both Linux and Microsoft on a global OS scale.

 The future is... Darwindows? | Tech News on ZDNet
And it's never been easier to get; all you have to do is install Darwin, the BSD derivative that underpins Apple's forthcoming MacOS X. Darwin is Mac OS X minus the singing and dancing Aqua/Quartz GUI, minus the Mac "Classic" emulator, and minus the "Carbon" API for newer Macintosh binaries.
Darwin supports G3s and newer machines -- "everything supported by MacOS X server" -- though there are reports of limited success with older machines, too.
Darwin on its own is not for the faint of heart.

 OpenDarwin   (Site not responding. Last check: 2007-10-09)
OpenDarwin was originally created with the goal of providing a development environment for building and developing Mac OS X sources as well as developing a standalone Darwin OS derivative.
OpenDarwin was meant to be a development community and a proving ground for fixes and features for Mac OS X and Darwin, which could be picked up by Apple for inclusion in the canonical sources.
Availability of sources, interaction with Apple representatives, difficulty building and tracking sources, and a lack of interest from the community have all contributed to this.

 Blog for wsanchez
We finally finished renaming the Darwin servers so, for example instead of www.publicsource.apple.com, we're using www.opensource.apple.com, which is much easier for people to deal with (the old names still work, naturally).
The goal there is to finally sync up Darwin's BSD libraries to more current code, and set it up so we have an easy way to keep that up.
At one point, I was talking about the BSD libraries which comprise the system framework, and when I got to curses I explained that curses is the "Cocoa of the command line." Apparently that's a lot funnier than I had expected, because the whole room busted up laughing.

 BSDCon 2000: A Small, Tasty Conference
Darwin is an adaptation of technology from several Open Source projects (e.g., Apache, FreeBSD, GNU, Mach, and NetBSD), supplemented with some innovations such as the I/O Kit, Apple's new, object-oriented driver framework.
It is unclear what the audience of Darwin will be; my suspicion is that it will consist mostly of technically-oriented Macintosh users who will use it in conjunction with Mac OS X. In short, these folks may not ever run Darwin as a separate entity.
At the same time, the BSD community is adapting itself to meet changing conditions.

 SystemStarter and the Mac OS X Startup Process
SystemStarter is part of the BSD subsystem in Mac OS X, now known as Darwin, though it's creation predates Darwin as an open source project; it was therefore created by a single author, though it now enjoys several contributors.
Written by Wilfredo Sánchez as an employee of Apple, SystemStarter was first publicly released in Darwin 1.0 and remained mostly unchanged through the release of Mac OS X 10.0 (which corresponded to the Darwin 1.3 release).
Mach ports were chosen for the IPC mechanism because Darwin's CoreFoundation library, which SystemStarter already used extensively to manage its internal data structures, provides a simple API for sending messages between processes using Mach ports.
