Developer Frans Pop, author of debtree, posted an article showing the evolution in size of the GNOME desktop environment in recent Debian releases. The picture he paints isn't particularly pretty: the default GNOME install has increased drastically in size over the years.

It's there and it's as useless as the linux one.

Rule one in Linux code land: don't believe anything Kroah Hartman says. I'm in full agreement with you on devfs. I used it, I liked it, I adapted a few drivers to use it, and followed the saga around it closely, essentially Greg "Arsehole" KH drove the devfs maintainer away by being a complete ass. Udev is the dumbest idea ever, why have a userspace daemon manage something that originates in kernel space in the first place? Oh, and as for your major/minor numbers, have an ls -l on your /dev... yep, device nodes still have them. At least most distros are smart enough to put udev's tree on a ram disk, but this is a cludgy workaround that shouldn't be necessary. Solaris, FreeBSD, OS X... and just about every other UNIX out there has used a devfs for years. Only in Linux land could an inferior idea displace a superior one because of loud voices.

I'm sure you've read about Greg defending udev, but here it is anyway:
http://kernel.org/pub/linux/utils/kernel/hotplug/udev_vs_devfs
Sounds convincing enough for me.

That was indeed a major FAIL. I knew that major and minor number still exist. What I meant is now they don't mean anything anymore, they're just a pool of numbers that are not bound to any specific driver.
These days it looks like distros are trying to make their boot times shorter. I wonder if they're going to open up the devfs bag again.
I think what shocked me most when I had to switch to udev was how much it slowed down booting — Even with a tmpfs. I told myself: "oh well, maybe it'll improve over time". It didn't.
My ethernet card jumps to eth2 instead of eth0 for no good reason once in a while. Which pisses me off because I've got to go edit /etc/udev/rules.d/blabla and then modprobe -r driver ; modprobe driver. No such problem with devfs. Fortunately I don't reboot often.

"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.

Google 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.

"During its Keynote today, Google announced new features coming to its flagship search function - you know, that thing we all started using Google for. VP Amit Singhal spent some time discussing what Google's search functionality will eventually morph into. Google's strategy is summarized by three words: answer, converse, and anticipate. Singhal explained that many of the pieces of these upcoming changes can already be seen in products that Google has recently introduced - namely, Google Knowledge Graph and Google Now, with perhaps a splash of Google Glass, too." I hold on to my hat every time Google changes Search. It's such a vital product in my daily life.More News »

FreeBSD has a devfs which is quite a different beast from udev on Linux. With udev you have a tmpfs mounted on /dev and udev, a userland daemon, populates the /dev directory with whatever info the kernel sends it. It's fat, slows down boot time and there are the problems you mention with the ethernet cards amongst others. Devfs on the otherhand is in the kernel and is slimer, and orders of magnitude faster. Linux used to have a devfs (I used it full time, never had problems with it) but it was deprecated because the code was said to be hard to understand and no one wanted to fix the races devfs was said to have. Kroah-Hartmann's udev was chosen instead. And this guy said that devfs was flawed by design. Nevermind that devfs has zero problems on FreeBSD and Haiku for example. But udev does have one advantage, it doesn't rely anymore on the minor and major device number scheme. That makes it possible, according to Kroah-Hartmann, to plug-in much more devices which is needed because of USB etc... Bottom line let's wait and see when FreeBSD and Haiku run out of minor/major device numbers ^^
