    Backing up the installer, or indeed the installed binaries, does very little good if the game needs to connect to an authentication server that has gone offline. Heck, even if the server is still online, your authorization may be refused on the grounds that the current installation is different from the first one, and you're only allowed to install once (the number varies, some allow as many as 5 times - which is probably enough for most people, though not for all - but in any case there's no guarantee your backup will work).

    I was just thinking this, and was surprised nobody had commented. Theoretically, yes, I think it could. However, it would be very difficult to make a sufficiently large magnetic field with sufficent strength, and I think you could only do it on one deck at a time - the magnetic field would otherwise probably prefer to go through the deck, rather than the corridor or whatever.

    Much worse, however, is what happens when anything strongly ferromagnetic enters the field. *You* might get accelerated download at something approximating 1 G (or even a fraction of it) but that wrench you're carrying might become very hard to hold onto, and I strongly suspect it would destroy a computer hard drive. Solid-state storage might be OK, but the induced electric field as the wires enter or leave the magnetic field could do some pretty awful things.

    We go over the theory and history of operating systems, and in particular kernels. We consider the inherent trade-offs in scheduling and other resource allocations, consider ways to prevent deadlocks, and so forth. The course is partially pure theory (ideal algorithms, the theoretical advantages of different kernel designs, etc.), partially discussions of operating system features in the real world (processes and threads, memory mapping, hardware abstraction, program loading, etc.), and partially hands-on experience.

    The NT or Linux portion of the course is simply a question of which real-world kernel we get hands-on with. Admittedly, we learn a fair bit that is specific to that kernel - having taken the one that uses the WRK, I know quite a bit about NT's IRPs (I/O Request Packets, data structures used to communicate between kernel components), for example - but the class is NOT a study of a particular operating system. We simply choose a particular implementation that we want practical experience with; in a course with only 10 weeks for instruction, there's really not time to study the implementation of multiple kernels.

    OEM editions of Vista (actually, of any Windows release, but its particularly noticeable with Vista) are absolute shit. Anybody on this site should know to *always* reformat and do a clean install. OEMs replace system functionality, bundle unneccessary performance-eating software, and include unstable drivers that cause BSODs. A clean install will run smoothly on a laptop with 1GB of RAM, a single-core 1.8GHz Turion, and integrated video (I've done it, and no I didn't disable halpful stuff like the search or superfetch). It won't crash randomly as long as you use reliable drivers (sometimes it's hard to be sure, but most non-beta WHQL drivers are fine). Framerates in games will be within 5% of XP (admittedly wth the GPU it had this isn't saying much).

    OEM installations of Vista are responsible for a large part of the public's low perception of Vista. I've given a few people clean installs (at no cost to them, using the key that came with their computer) and turned their perceptions around pretty much 180 degrees. Unfortunately it's a hassle to do once everything is already installed, but doing it once will save a lot of frustration later.

    If you sincerely think that the average user is happier to hunt down a option somewhere in their new program that sets what file types it opens (as opposed to being presented with a one-time dialog during installation) you are so far out of touch with the reality of how people use computers that I honestly can't help but wonder if you're just trolling.

    Besides, you're still not addressing the main point of the GP. On a Mac, you're not even able to set those defaults. They're part of each file's metadata, editable only on a case-by-case basis.

Dual-booting is annoying, but assuming you have a Linux system that actually hibernates reliably it doesn't actually take that long.

    The UW offers OS courses on both the NT and Linux kernels - Neil chose to take the NT one, but in terms of degree progress the Linux version of the OS course is exactly equivalent. The CSE undergraduate labs are a mix of Windows and Linux boxes. The department offers a few Windows servers for student use, but the majority of the servers, including the file server, mail server, and cycle server are all Linux-based.

    As for the required courses, one of the earliest courses in the curriculum teaches basic Linux knowledge, ranging from shell familiarity and manpages to scripting and regular expressions, plus gcc, make (and writing makefiles), and so forth. Later classes include security (one of the programming projects specificaly requires Linux and GDB knowledge), embedded systems (the latter half of the class uses an ARM chip running Linux, and we are required to modify a kernel driver and use the ALSA API), Networking (this one varies, but usually involves developing for a device like a router or N800, running Linux).

    For those who don't know, the WRK is a mostly-complete source code distribution of the Windows 2000 kernel (NT 5.0). It's made available for academic and research uses. While the source isn't included for every single component, there's more then enough there to understand how the kernel works, how its components communicate, and to write your own extensions or modifications (system calls, changes to the scheduler, doing things at different points during initialization, modifying included drivers and so forth).

    UW also offers OS courses based on the Linux kernel; which you take is a matter of preference as they satisfy the same prerequisites and are treated as equal in terms of degree progress.

    While partially true, this is much like the way that, a hundred years ago, natural oild wells were under enough pressure that the oil could be extracted without pumping at all. This made oil cheap and plentiful, which led us to build an economy around it, such that when the easy oil ran out, it was economically feasible to drill for deeper deposits, pump the oil out of the ground, use offshore rigs, and so forth.

    Similarly, just because the easily-accessible natural U238/U235 deposits will run out within a century or so doesn't mean that we can't use them - there's more down there, it'll just cost a bit more to extract.

Now lets suppose my son also likes playing games, and when he's not on his PC (separate from mine) he's on the Xbox 360.

    Only if you assume that per-capita pollution remains the same. This is a completely unreasonable assumption - if it were true, the US wouldn't have ever become the massive polluter that we are today, simply because we have 1/12th or so of the total global population (yet produce a far greater percentage of the total pollution).

    Japan's population could drop by 50% in 20 years (they probably won't, but it could) and they would still end up needing more energy, most likely. It's not just a matter of homes - there's also manufacturing, transportation, computing (data clusters are a significant consumer of US energy supplies), communication, and all the myriad other things that require energy in modern society (and will require more energy in future society). People will be carrying more hardware that needs more electricity to charge (it'll get the same battery life, but simply because battery technology is also improving), using electric-powered cars more (which may use less total energy than gasoline-powered cars, but use far more electricity), and houses will have more power-using technology as it becomes more affordable and usable.

    Mind you, I completely agree that overpopulation is problem that needs to be addressed. However, to claim that we shouldn't be trying to increase our resources - in particular, trying to increase our supply of a resource for which demand grows far out of proportion to population - is foolish. The best option is to address both at once, and create a better life with a stable and sustainable population, without hindering technological advancement. The approach under discussion here is a partial solution, and only a fool as great as you seem to be would imply it either solves nothing or solves everything.

    GNU (recursive acronym for "GNU's Not UNIX!") is an operating system. The only portion of the system that is called HURD is the kernel, which is certainly not an entire OS. It's quite possibly the most important of one, but does not constitute a complete operating system by any means.

    As for "redefining words" you're doing more than a bit of that yourself. A kernel is "the central or most important part" and, in a computing context, "The essential part of Unix or other operating systems, responsible for resource allocation, low-level hardware interfaces, security etc." (http://dictionary.reference.com/browse/kernel) Note the key word "part" that is present in both definitions. A kernel, such as Linux or HURD, is definitely only part of an operating system.

Referring to an OS by its kernel is not a universal practice - OS X is almost never referred to by the name of its kernel (XNU, a derivative of Mach), although of Windows such as Vista or Windows 7 are occasionally referred to as "Windows NT" or even "NT" - but it suffices for the purposes of Linux. That said, it's understandable that Stallman and the GNU project in general would like acknowledgement of how much of the OS that most people call "Linux" was not written by, or in any conjunction with, Linus Torvalds.
