Actually, a built-in LVM makes a lot of sense if you stop to think about it; many of the things a LVM does could benefit from information only the filesystem has.
Which is exactly why this strategy is so stupid; they'd sell more than twice as many at $200 as at $400, and right now it's all about achieving volumes. This is even worse than Steve Jobs' refusal to sell NeXTcubes to non-students. I just hope the OPLC project has a reincarnation past Negroponte's irrational fear of capitalism the same way the NeXT system was reincarnated as OS X.
The US MOAB is a large but conventional high explosive; it may well have more raw power than the FOAB, but it's focused on a (relatively!) small area (shock wave power drops off as square of distance). (Not to be confused with the US's next-largest bomb, the 'Daisy Cutter', which *is* a fuel-air explosive.)
The new Russian FOAB is 'themobaric'. Not quite a conventional fuel-air bomb; the explosive is still a standard explosive, but distributed by a smaller primary charge so that it scatters into a large cloud before exploding, spreading the energy much more evenly over a large area.
Deferred, maybe, but not for more than a few seconds, and when it happens it means more disk seeks...
It's long been standard practice to disable this on, eg, news/mail spools (anything with large numbers of read-mostly small files). The new plan of, if I understand correctly, only updating atime when the file is modified or if the new atime is more than 24 hours after the current atime should provide nearly the same functionality with practically none of the performance hit.
Your odds of being killed by an asteroid are much less than by lightning, because it is so much less likely to happen. Just because something kills lots of people when it extremely rarely happens doesn't mean it's more likely to happen.
No, but it's more likely to happen to you. If car accidents that kill 10 people happen with the exact same frequency as car accidents that kill 1 person, you are 8x more likely to be killed in the former than the latter.
My six-year-old daughter is currently enthralled with Cyberchase, a PBS cartoon that actually does a pretty respectable job teaching basic math concepts. Her singing of its repetitive and insanely peppy themesong is driving my out of my mind, though.
The problem with NAT and firewalling, both, is that they're broken by design. They're attempts to add features to the protocol/application/OS layer that are implemented at the network layer. It doesn't have the necessary information to do the job properly! So we end up with godawful mostly-kinda-works klugdes like timeouts on idle TCP connections, etc....
I spend a fair bit of time tracing down network-related application issues, and let me tell you, NAT and firewalling are the work of the devil. Look, I'm all for a Linksys in front of your home Windows box, but please please, can't we kill this nonsense off once and for all?
For 'nationalization' read, of course, 'rationing of basic foodstuffs' (there's a nice article about this in that notorious right-wing rag, the New York Times). And democracy without vigorous protection for minority rights rarely ends well.
Mostly, though, it's just too tedious to work through a chain of no-true-scotsman arguments with the folks who are sure that Socialism is bound to work this time. No doubt in ten years when Chavez is still absolute ruler and has turned Venezuela into an unambigious Zimbabwaean-level disaster, this will all be down the memory hole and you'll be hyping up the next big thing.
One of the nice things about methane (like LOX, and unlike kerosene or for practical purposes hydrogen) is that it's potentially self-pressurizing; keep the tank at the right temperature, and you can maybe dispense with the pumps entirely. Depending on your cost-sensitivity and the performance you're trying to hit, this might or might not be a big win...
Maybe not a full semester, but at least a couple of weeks in a discrete math class should be devoted to information theory. Even if you can't implement a state-of-the-art one, you should understand the basics of error correction, cryptography, data compression...
The interesting point the court made is that antitrust law is made to protect consumers, not businesses. Selling below cost violates antitrust only if it's part of a plan to drive out your competitors and jack up prices later. Since the GPL doesn't allow the 'jack up prices later' part, there's no anti-trust harm to consumers, and no grounds for action.
That's the bus speed; the disk can't actually sustain I/O at anything approaching those rates. (If you're doing all reads serviced out of the little internal cache on the HDD, sure, but try writing a few hundred megabytes of data and see if you get rates approaching the interface bandwidth.)
First of all, disk drives are advancing faster than tapes.
But the problem is worse than that. Different aspects of disk drives are advancing at different rates. Capacity is increasing faster than interface speed is increasing faster than access speed is increasing faster than block reliability.
Consider an old 500MB drive from the mid-90s; it takes maybe a couple hours to read every block on the drive, and odds are that you won't have bad blocks before the disk dies entirely.
The new 1000GB disks we'll have soon, though... you're pretty much guarenteed some of the blocks will go bad before the disk fails; there are just so many of them. And if you can read at 10MB/second, sustained (pretty respectable, I think?), it literally takes 24 hours just to dump all the data from the drive, never mind back it up to something else.
The whole model of 'back up your fixed media to removable media' is not going to work anymore. It does not scale up to modern hardware. I think the answer will be some wacky combo of raid and file-system version control, but YMMV.
Assuming the linksys is doing NAT (and if you don't know, it probably is), that's most likely ok. All your PCs are sharing one internet address, and that means they'll only be able to make outgoing requests unless you frob some settings. If an incoming request (eg, from one of those worms) comes in, the linksys has no idea which PC it's intended for and just drops it.
The iTV was targeted at $299, so it isn't any cheaper. (On the other hand, the iTV doesn't exist yet, so this is a bit unfair to Neuros). And with a DSP you don't need much of a CPU, if video streaming is all you're doing. It'll be interesting to see what kind of processing Apple puts in (and it is OSX based, or a glorified iPod?) - I don't think there have been any reports about that at all.
The Neuros could win some sales based on hackability, though...
Is it just me, or is this pretty much what Apple's upcoming iTV will be? The hardware sounds like it's pretty similar.
Useful mostly for streaming low-to-medium resolution video from PC to computer. Neuros adds the ability to record - maybe useful to an attached MP3/video player? (I guess you could NFS-mount a filesystem from elsewhere...?) In practice, I'd bet that's too much of a hassle to be worth the trouble.

Don't forget the German spies in the US during WWII who were tried and executed by US military tribunals.

Hey, if you're looking for somebody to pursue the case, it looks like Darl from SCO will be available soon!

Since they're being painted out in a thin layer, can we say that the secret to cheap solar energy is therefore Snakes on a Plane?
Which expedition also established that the penguins were tolerated by, or possibly pets of, the Old Ones.

This is also a very good step in the right direction, democracy-wise.
I'd say, democracy-wise, the ruler granting himself the power to rule by decree is a pretty bad sign.
big economic powers require more and more power to control their population
Well, Chavez's ongoing implosion of the Venezuelan economy should serve him in good stead, then.
Seriously, man, anybody who believes Venezula is a shining beacon of progress is a walking trimuph of Marxist ideology over reality.

er, so I did. Let me rephrase:
Yes, but you could put something much like this rocket as a second stage on top of a big dumb booster and maybe get to orbit that way.
It could be the top stage of a two-stage SSTO, though.
Obviously, Judgement Day will be triggered by Skynet in a final, frustrated attempt to eliminate spammers.
