That looks like the best confirmation of the problem, instead of debunking it. They needed a Focus RS suspension instead of the regular Focus just to cancel out the extra unsprung weight of the wheels - and part of the premium price of the Focus RS suspension is its use of lightweight materials so the actual increase in unsprung mass wasn't as great as claimed. Of course engineers can fix the problem given enough money.
The reality is that when a wheel hits a bump, all the unsprung mass of the wheel suddenly undergoes a large acceleration. 'That's pretty much the definition of unsprung weight. And with a fixed, F=m*a also means the force on the wheel is proportional to the unsprung weight. This is 17th century physics.
Welcome to the conversation, intellectus superiosa slashdotus. Confronted with the results of actual engineering studies by experts in the field, which you could actually learn something from, you repeat the same tired old preconceived crap with no analysis whatsoever to support it.
An electric car does not have to have reduction gearing at all. In fact there are electric cars that do not. Repeat, do not. Believe it. In fact you can also do away completely with mechanical brakes.
If Tesla and GM and Nissan and others were all too timid or conservative to do it right, that is their problem.
Wake up, there is no "safe" or "unsafe" in the absolute sense. Many millions of smokers never suffer from appreciable ill effects. Many others suffer an agonizing death likely attributable to it.
Smoking entails a risk. So does exposure to elevated radioactivity. And guess what, so does walking. If all the elderly crawled on the floor everywhere they went, or wore big honking foam rubber bumpers, there would be a lot fewer broken hips, and broken hips are a very significant morality risk for the elderly.
It's nice for you guys that your needs do not encompass any significant amount of data, but there are plenty of guys with a lot more imagination and requirements. I have a personal server with two 6-drive (3 TB each) RAID-Z2 double-redundant pools. That's a total of 24 TB usable storage.
The two pools are currently 85% and 78% full.
My intention is to have a second server with the same storage specs as the first, with the pools synced to those in the first server. That will give me four-level redundancy. So far my second only has one of the pools installed (I ran out of funds).
If I scare up the funds, you can damn well bet I will not only finish the second server, but I will upgrade the disks to at least 6-8 TB each, and hopefully more.
Oh I also have 6 more 3 TB drives (so 24 total) and 22 2 TB drives installed in various other boxes. Let's not even count the pile of 1 TB and smaller that I don't even consider worthwhile to have installed any more.
As long as only a single head is active at a time, reading a single track at a time, transfer rate is proportional to LINEAR density, not AREAL density.
1) If one is not using ZFS with RAID-Z2 (double parity) or RAID-Z3 (triple parity), one is an idiot. I think we're in basic agreement, but I'm just emphasizing that no crude RAID technology can compare with ZFS.
2) You do understand that MTBF has nothing to do with design lifetime. Right?
Desktops and servers are hardly the entirety of the world. They don't even dominate it. Ever heard of ARM? If Linus felt that way about 32-bit, there would be no Android, or it would have to develop its own kernel. Sheesh. FreeBSD and linux are found in routers and such with very weak CPUs.
What are you, on crack? The Republicans in the House can pass pretty much anything they want. That's a fact of life for now. That doesn't get it through the Senate. Even after January it doesn't fly through the Senate because of the filibuster/60-vote procedure. And even if it makes it through there it sure as hell doesn't get signed by President Obama.
It would have to be a pretty rigorous, file-compare-before-and-after, restore check, because just verifying that they read back without any read error would not detect backups that were perfect copies of data that was sitting corrupted in the backup server's RAM.
Oh get over it. RAID protects against *some* data loss scenarios and not against *some other* data loss scenarios. Pretending that it doesn't protect against data loss at all is just silly.
And Amazon says the battery in their Kindle ebook reader lasts 4 weeks - fine print: when used 1/2 hour a day. Pssst - that is an actual 15 hours. And they have a graph with the line for their battery dozens of times longer than the competition which has - ready for it - 13 hours battery life.
I guess my car will only need its tank refilled once a year if I only drive 5 miles once a week.
As pointed out elsewhere, silos are heavily-reinforced concrete. You'd have a gun barrel effect directing the blast straight up.
Are you high? All the energy of a nuclear explosion is released within one microsecond. Matter does not have a chance to be displaced in one microsecond. For a 125 kT subterranean burst in solid rock, the melted cavity will be 40 to 120 meters in diameter. The crush zone will be 150 to 200 meters in diameter. To be contained, the blast would have to originate beneath 500 meters of rock. A Minuteman missile is less than 20 meters high. Your silo is not much deeper than the length of the missile; 25-30 meters at the most; and furthermore the warhead is at the top.
The lid of that silo is either going to be vaporized or ejected very quickly, but it's not going to prevent the vaporization and melting of the concrete walls, which might as well be tissue paper, and a bunch of the surrounding rock or soil, and then many tons of that radioactive material are going to blow into the atmosphere.
Toughness is a perfectly good engineering term with a defined meaning. Look it up. Wikipedia is a decent start. "In materials science and metallurgy, toughness is the ability of a material to absorb energy and plastically deform without fracturing."
Preposterous. Review the Pythagorean Theorem. The diagonal is the square root of the sum of the squares of the sides. A 24" 16x9 monitor is 20.9x11.8". A 24" 16x10 monitor is 20.3x12.7".
11.8" vs 12.7" is 0.9". How do you get "a few inches" out of that? The difference is about the size of a stamp.

If you knew what you were talking about you would know that Blu-Rays are already H.264 or comparable, and they are GIGANTIC.

That's pretty much the BLOODY OPPOSITE of net neutrality, you daft so and so. Are you this irrational on all subjects?
"But unsprung weight" is a tired old preconception. Maybe if you bothered exploring the references provided and elsewhere you would be relieved of some of your misconceptions.

WTF, overwrites the MBR? What half assed OS does this attack? Windows?
Except for the little detail that it is NOT A GODDAM MODEM. Misusing terms does not change their meaning.

Funny, they're binary packages, don't have to compile them, and it doesn't look broken to me. If it isn't xorg-server 1.16, SO WHAT?
OK I'll match your anecdotes.

And FreeBSD tells you that 32-bit will hamstring ZFS, so if you want the good stuff on FreeBSD it's 64 bits for you.

So really, who cares?
So that's really $40/2.5TB in the real world. Who has large amounts of data that is compressible? NOBODY.
It would have to be a pretty rigorous, file-compare-before-and-after, restore check, because just verifying that they read back without any read error would not detect backups that were perfect copies of data that was sitting corrupted in the backup server's RAM.
Where? Put up, or it's a fiction. And they had better be prices for new product, and current production.

In what universe do hot water heaters store steam? And in what universe is steam "explosive"?
Toughness is a perfectly good engineering term with a defined meaning. Look it up. Wikipedia is a decent start. "In materials science and metallurgy, toughness is the ability of a material to absorb energy and plastically deform without fracturing."
It's typically measured by an impact test.
Or maybe functions are chapters, not paragraphs. Ever think of that? Chapters are not neat little things you can see all at once.
