"I am very happy about the direction in which the Mac OS X GUI is going, although sadly many Mac users aren't interested in (or don't know about) the "lower levels" of the Macintosh Operating System. Have you ever wondered why the Terminal greets you with the words "Welcome to Darwin"? Why do BSD and Mac OS share certain bits of code? Why does Wikipedia describe Mac OS X as a graphical operating system? Today we're going to take a look at the underlying open source technology which powers your fancy Leopard OS - the hidden core set of components, named Darwin."

Moulinneuf, you are speaking in the language of the backside.
Darwin is a project that contains the underlying OS framework which OS X is built on. Darwin inherits a lot of things from NeXT and NEXTSTEP/OPENSTEP. The driver model was always different in NEXTSTEP. This is not some Apple conspiracy, it's a driver model designed in the mid 80's that was "better than what was there already" because of the nature of Mach (attempting to be a Micro Kernel and not monolithic, like BSD is/was.)
OS X is an OS based on the Darwin framework. It is a seperate project that shares source, but is not directly related to Darwin outside of the fact that Apple provides *their* Darwin changes in *their* repository.
Whether you like it or not, most of your claims could fertilise my lawn.

"At the end of a week in which Electronic Arts confirmed it wasn't developing a thing for the Wii U, one of the software engineers in EA Sports' Canada studio, in a series of since-deleted tweets, disparaged the console as 'crap' and suggested Nintendo should give up on hardware altogether. 'The Wii U is crap. Less powerful than an Xbox 360. Poor online/store. Weird tablet', tweeted Bob Summerwill, listed as a senior software engineer at EA Canada, in a reply to a tweet posting a link about EA's no-Wii U news. 'Nintendo are walking dead at this point'." The Wii U is turning into the 21st century's Virtual Boy.

"In NixOS, the entire operating system - the kernel, applications, system packages, configuration files, and so on - is built by the Nix package manager from a description in a purely functional build language. The fact that it's purely functional essentially means that building a new configuration cannot overwrite previous configurations. Most of the other features follow from this." Interesting approach. A Linux distribution, sure, but with some very refreshing ideas about system configuration.

Appfour added, among other features, C/C++ support to its new version of AIDE. From Android-IDE, "Now you can write parts of your app or your whole app in C/C++ on your device. AIDE supports the Standard Android NDK toolchain (GCC 4.6 + Bionic, STL, ...). No changes are necessary if you want to build an app developed on a PC with Eclipse. C/C++ development is fully integrated: Build errors appear in the error list and files can easily be navigated to with Go to file. The editor supports C/C++ syntax highlighting."

Ars nails it: "The answer is that Google did announce what amounts to a fairly substantial Android update yesterday. They simply did it without adding to the update fragmentation problems that continue to plague the platform. By focusing on these changes and not the apparently-waiting-in-the-wings update to the core software, Google is showing us one of the ways in which it's trying to fix the update problem."

"It is good for programmers to understand what goes on inside a processor. The CPU is at the heart of our career. What goes on inside the CPU? How long does it take for one instruction to run? What does it mean when a new CPU has a 12-stage pipeline, or 18-stage pipeline, or even a 'deep' 31-stage pipeline? Programs generally treat the CPU as a black box. Instructions go into the box in order, instructions come out of the box in order, and some processing magic happens inside. As a programmer, it is useful to learn what happens inside the box. This is especially true if you will be working on tasks like program optimization. If you don't know what is going on inside the CPU, how can you optimize for it? This article is about what goes on inside the x86 processor's deep pipeline."

"It was the only moment I heard regret slip into Otellini's voice during the several hours of conversations I had with him. 'The lesson I took away from that was, while we like to speak with data around here, so many times in my career I've ended up making decisions with my gut, and I should have followed my gut,' he said. 'My gut told me to say yes.'" The world would've been a much different place - Apple would have been less dependant on Samsung for its chips, which probably would've meant less money for Samsung to develop its Galaxy business.

Glass is getting some love at Google I/O as well. New applications have been released - Facebook, Twitter, Evernote, Elle, Tumblr, and CNN. Perhaps more interesting: the newly announced Google Glass Developer Kit will allow offline applications and direct hardware access - great for hacking and expanding Glass' potential. This kit will really allow hackers to put Glass through its paces.

"But Beck and Merrill decided that simply banning toxic players wasn't an acceptable solution for their game. Riot Games began experimenting with more constructive modes of player management through a formal player behavior initiative that actually conducts controlled experiments on its player base to see what helps reduce bad behavior. The results of that initiative have been shared at a lecture at the Massachusetts Institute of Technology and on panels at the Penny Arcade Expo East and the Game Developers Conference." Absolutely fascinating stuff. I'm a League of Legends player, and to be honest, the community isn't nearly as bad as some make it out to be. I'm happy Riot games has the guts to employ science to address the issue.

"Android and iOS, the number one and number two ranked smartphone operating systems worldwide, combined for 92.3% of all smartphone shipments during the first quarter of 2013 as Windows Phone crept past BlackBerry for 3rd place. According to the International Data Corporation Worldwide Quarterly Mobile Phone Tracker, Android smartphone vendors and Apple shipped a total of 199.5 million units worldwide during 1Q13, up 59.1% from the 125.4 million units shipped during 1Q12." Windows Phone doubles from a few to twice few, iOS loser market share as its growth is slower than that of the overall market. BlackBerry continues slide into irrelevance.

In other words what Apple did was switch to a license away from BSD and add code but made it proprietary in order to restrict and control it's inclusion , they are also trying to suggest that there kernel was open sourced when in fact only some part was released.
No , as I said in real Open Source , there is no restricted code or license switching in order to control an addition , you may have different branding/naming and different code added but the code its always developped and available as Open Source.
[/q]Any Apple-branded proprietary libraries and drivers are not part of Darwin and thus aren't distributed freely. [/q]
That's where your wrong , they are removed in the Open Source release , there also Apple branded **derivatives** and **derivative** driver , thats why Darwin open source don't do what Darwin Mac OS X can do and don't have the same size and code.
Yes , rather its Free Software , but if one use your example it's the same as having the Linuz Kernel under APL with some proprietary adittion by Apple and the Linux kernel GPL by the GNU/Linux community , the difference with BSD is that the GNU/Linux community invested in it's kernel so that it's the proprietary version who is behind or very close , where as the BSD community as not invested in there own kernel to be on par with Apple. Also in real Open Source Red Har and Novell and the other commercial contribute code so that Debian and others can benefit from it too and vice cersa.
[/q]The same applies here: the base system (Darwin) is open-source, there just are proprietary libraries, drivers and applications running on top of it. [/q]
No , they are added to Darwin in Mac OS X , not on top of it. That's where you and your friends are getting confused here , code is removed from Mac OS X Darwin to Open Source Darwin. Also the addition on top of it of the derivative by Apple is also a problem under Real Open Source. Because your supposed to make and contribute Open Source addition.
But the real problem is not Apple or what they do in itself. It's what the BSD let them do and what BSD do not do to be on par with itself aka Apple Mac OS X and Darwin so called Open Source.

BSD as nothing as complete or as close as the above , only talking in Darwin.
Hence Darwin is what BSD could have been.
