The reason for symmetrical wings on aerobatic aircraft is that they impede the flow even more and allow much greater control, at the expense of fuel efficiency.

Wanted to clarify this. The reason for symmetric airfoils on fighter aircraft is that camber provides no additional lift (compared to a flat plate) in a supersonic flow. Lift coefficient is still linearly proportional to angle of attack at supersonic speeds. However, drag coefficients rise quadratically with increasing camber/thickness. Thus, supersonic fighters have very thin, very symmetric airfoils.

I think, sir, that you're talking a bit out of your ass. Supersonic fighters have thin airfoils for aerodynamic reasons but they are by no means required to be symmetrical. The F15 and F16 (both supersonic capable aircraft) have cambered airfoils. Drag increases as the square of the lift coefficient - camber increases the lift coefficient for a given angle of attack, and thus camber increases induced drag (the component of drag associated with lift).

The reason stunt planes have symmetrical wings has to do with the fact that symmetric wings are more efficient when flying upside-down than a heavily cambered wing. That is a state that most other airplanes actively try to avoid. You get the same amount of lift out of the wing at the same angle of attacks. The reason why they're thick is because thicker wings allow you to delay stall. Since stunt planes fly slowly, you don't really have to worry about the efficiency of the wing. That and stunt planes are NOT optimized for aerodynamic efficiency - simply the ability to generate tons of lift quickly.

Next time you cite one of Dr. Anderson's wonderful text books, please read it first.

This argument is true of _any_ system, however, not simply these particular ones. If I can get a sysadmin to run this binary that I've put in my home directory, then I can fully compromise the entire machine.

There is no way to secure the interior completely without making it unusable. There are simply levels of security.

Any time you introduce humans into the equation, there is ALWAYS a possibility of compromising a secure system. So by that extent, maybe the test has unreasonable expectations?

I don't see how your comment is relevant to what I said.

The response I was posting about was how their proposed non-NAND option isn't an option at all, suggesting that perhaps Intel had done their homework to use NAND memory, and not DDR (or some newer version of it) memory.

Apparently, you didn't read my comment in the context of the OP at all.

Comment Re:HW buffer for drives (Score 2, Informative) 271

Sounds like a good plan. Throw cheap battery backed memory, 4-16Gb onboard to act as a transparent buffer between harddrive(s) and system.

Do you mean gigabit or gigabyte? Also, 16 gigabytes of RAM right now isn't very cheap at all. The cheapest DDR2 memory I've seen is about 12.50 dollars per gigabyte, so that's an additional 200 dollars per 16 gigabytes. Is that a good price to pay for some potential increase in speed? IMO, that's what I'd call "extremely hard to justify" for a consumer.

RAID cards have done this for ages, but it's becoming real option for desktops as memory price keeps declining.

Meh, even the most expensive RAID cards loaded up with tons of RAM aren't as fast as a couple of Intel SSD's right now, so why bother with the expense?

First of all, DDR RAM is not cheap (at least, not compared to NAND RAM). It costs significantly more per gigabyte than even the most expensive of Intel's offerings for SSD's. While it should provide more theoretical throughput than any SSD, benchmarks at various places (http://techreport.com/articles.x/16255/1) haven't shown that to be significant yet, at least from the end user perspective (some synthetic benchmarks show that the RAM based disks can be faster than SSD's, but translating that to real world usage scenarios by consumers doesn't quite show any tangible benefits).

DDR RAM uses up a very large amount of power per stick compared to SSD's do. I remember seeing the power consumption of one of the DDR2 based "volatile hard drives", and it was higher than spinning drives (at least at idle), and wasn't particularly faster than the best of intel's SSD's.

So sounds like DDR RAM on board is expensive, power hungry, and doesn't provide that much of a tangible benefit to consumers. Tell me again why it's a good idea?

Reading a bit more about the patent dispute between Curtiss and the Wright company, it becomes clear that the Wright brothers wound up not being a financial success not because of lack of patent collections, but on moneys spent on defending the patents.

If that's the case, then that spells the doom of TiVO.

Having been through the patent process, it became clear to me that filing a patent does one and only one thing - it means that you can use your patent. Defending your patent (by litigation) ultimately will bankrupt you, unless you have a law firm on retainer (which in and of it self can bankrupt you if you're a very very very small business of one or two).

Things probably would have wound up being a bit different for the Wright Brothers had they simply accepted Toulmin's initial offer of being on retainer...

The ONLY thing FOIS had over Tivo was the multi-room DVR feature worked, and worked fairly well. Tivo definitely has room to improve in this area.

Interesting - I had thought that the Tivo HD that I bought has that as a selling point - it provides multi-room DVR features (albeit with other Tivo's or any generic computer running Windows/MacOSX).

I'm the same way with a lotta stuff. Even though I had Cartographer in WoW, I had to open up all those zones completely.

WoW does that now. By exploring every spot on the map (actually, just removing all of the fog of war), you gain an achievement, and a new title "the Explorer" that you cahttp://games.slashdot.org/story/09/08/08/0345231/Finding-New-and-Unintended-Ways-of-Playing-Games?from=rss#n add to your name.

Ultima 3 was the last Ultima I did anythingn like that for. I killed a monster in EVERY square, populating the entire map with treasure chests. I suppose you could say that it eliminated all random encounters (since monsters were boxed in by the treasure chests) and helped me to focus on playing the rest of the game, but it took a really really really long time to actually get to that point.
