The Incredible Shrinking Operating System
snydeq writes "The center of gravity is shifting away from the traditional, massive operating systems of the past, as even the major OSes are slimming their footprint to make code bases easier to manage and secure, and to increase the variety of devices on which they can run, InfoWorld reports. Microsoft, for one, is cutting down the number of services that run at boot to ensure Windows 7 will run across a spectrum of hardware. Linux distros such as Ubuntu are stripping out functionality, including MySQL, CUPS, and LDAP, to cut footprints in half. And Apple appears headed for a slimmed-down OS X that will enable future iPhones or tablet devices to run the same OS as the Mac. Though these developments don't necessarily mean that the browser will supplant the OS, they do show that OS vendors realize they must adapt as virtualization, cloud computing, netbooks, and power concerns drive business users toward smaller, less costly, more efficient operating environments."
Every CPU cycle that the "OS" uses is stealing cycles from processes that could be doing productive work for me. So yes, OSes can be slimmer. Regardless of how much memory or CPU exists. The attitude of "eh, we've got 4 GB of RAM" is why we have such bloated OSes and applications to begin with. As for your suggestion about a distribution with all settings in a database. It's called the Windows Registry, and we all know how well _that_ works.
I think you live in an insulated world. Most (non IT) businesses print reams of paper every day, and academia uses paper like it's going out of style (which I guess it is...).
I never understood why so many services were running by default in the first place.
I always thought it would make more sense to provide three big buttons on setup as well as an advanced tab. Those buttons are the presets: everything off, the most popular stuff on, and everything on. The advanced tabs would let you tweak the specifics.
There's so much extraneous crap running on a typical Windows install it just blows me away. I'm less familiar with Linux and OS X but from what I've seen they are as guilty at times.
Incidentally, this also brings up my beef about software updaters. I have no problem with them running once a week at startup, checking the net for an update and terminating. But these fuckers remain running in the background constantly like Google updater. Look, do I really care to know the second a new program is released, a new patch? Look, why can't you just tell me the next time I reboot? Or hell, just run the updater when I execute the specific program and piss off when finished.
I understand that modern software is really complicated and I'd feel a little less free to complain about bloat if I knew everything that went on in the background. Well, I still wonder what things would be like if I were God Emperor of the World and said that nobody could buy faster machines for a decade, they had to stick with what they had. We see that happen with video game consoles, having a fixed platform to develop for over a period of years, the optimizations that are developed. PC's move so damn fast that by the time anyone figures out the hardware there's something new to write for. And management pays for new features, not optimization. But if they couldn't just demand people buy a faster computer, if they had to work within the resources at hand, I bet our stuff would be running two or three times faster by the end of the decade, just from doing it right the second time.

If you really want to see "slimming down the operating system", check out QNX, which is a true microkernel used mostly for embedded systems. The kernel just does memory, CPU, timer, and process management, plus interprocess communication. Everything else is optional. Networking, disk/file system support, display support, window management, etc. are all user-level processes that you can include, or not, when making a boot image.
The unusual feature here is that the components really are independent. You can have networking without a file system, or a file system without networking. If the machine has no display, you don't have to include any of the "console" stuff. Even error logging is an option, and can be connected to a display, a window, the network, or a file.
But this isn't what the original article meant by "just enough operating system". They're thinking more of bloated distros.
I hope "just enough operating system" means the ad-funded preloaded crap goes away. Remember Dell charging $50 extra to get rid of all that junk?
It struck me as kind of strange that they'd strip out something like CUPS...I mean, don't even most normal users like to print documents?!?!
