If you don't have to fit a bunch of them on to ships they can be made big enough to carry more fuel for more range. They could be as fast to the target as a conventional cruise missile, cheaper than battleships and aircraft carriers hauling them to where they're needed, and cheaper than ICBMs too.
Anyone with an ounce of sense wouldn't be wandering into the unlocked basement of a house in the woods without knocking on the front door first.
I agree that 'shoot first, ask questions later' isn't necessarily a smart or comapssionate tactic, but neither is wandering into other peoples homes uninvited and unannounced. People with good intentions don't go sneaking around, and people that concerned about the security of their homes don't leave doors unlocked.
Ever heard of the Tueller Drill? Police training teaches that violent attacker armed with a knife and closer than 21 feet away can consitently reach, attack, and greivously injure a victim armed with a holstered gun before the victim will be able to draw their gun and fire.
Not only that, conflicts with knives are consistently more lethal than shootings.
Guns are not death-rays and it takes far more training, skill, and practice to use them effectively than you may realize.
Refutation. I'd like to know how you can tell when an intruder intends to just steal your DVD player, rather than kill you and rape your wife and daughter.
My point is that just because somenone else is paid to clean up your messes, that doesn't justify you in continuing to make them or nullify their right to be upset at your disrepectfulness. I just used extreme examples just serve to clarify my point.
So what do you do for a living? How are you going to feel if I, for no good reason, decide to habitually make your job a little harder. Are you going to complain? After all it your job to deal with it, isn't it?
Why should a fireman complain about arsonists? If he needs to put out a fire, that's just part of his job. Why should a sysadmin complain about hackers? Keeeping them out is just part of doing his job. Why should a busboy complain if someone dumps their leftovers all over their table? He's paid to clean up isn't he?
Whoah there. The BGA rework station that I use almost every freaking day didn't cost nearly 20K. It works just fine on everything I use it for, which is up to 388-ball BGAs. IIRC it was under $3000. It takes me at most 10 Minutes to replace any component, including 208-pin QFPs and 388-ball BGAs. What really takes time is figuring out just which component needs replacing.
You've hit on a very interesting aspect of performance mods. There are many times when mixing and matching parts from the manufacturers models and years can yield BIG gains with little headache. My 1987 BMW 325e started with 121HP, a 2.73:1 diff ratio, and a 0-60 around 9 seconds. It has since recieved a 325i engine with 168HP and a 4.1:1 differential from a 325i automatic. These two mods alone are worth a nearly 3 second drop in 0-60 times.
I've seen guys that have built some amazing Porsche engines by mixing various years' heads, cylinders, pistons, and cranks - easily doubling their power output using nothing but factory parts.
Once you start talking to the experts in a particular car you can learn some impressive tricks for building performance (You run into trouble when the "expert" is elling somthing). For example, later 1st generation RX-7s have an anti-backfire valve in their intake manifold that can cause airflow restriction, you can gain some cheap horsepower by switching to an earlier intake. Or, you can greatly improve the braking on a Porsche 914 by replacing the calipers with ones scrounged from a BMW 320i.
Have you ever seen a ring made of 24K gold that's been worn for a while? Pure gold isn't much harder than lead and will get beaten up in a hurry. 14-18K is much better suited to everyday jewelry. Although it is a pretty crappy alloy that would turn fingers green.
How can this possibly be modded as informative? Refering to Superman as evidence and then posting a link that only talks about diamond finds around the great lakes does not convince me of the posters veracity.
IMO the best way to handle that, since the servo is mounted to the steering coulmn shaft, would be to build the system as a brushless motor with the rotor integrated into the shaft. No extra moving parts coupled to the shaft and absolutely no extra resitance if the motor dies.
For the rest of the world "by-wire" is defined as the lack of any physical connection. This is the heart of the whole controversy. When a drive-by-wire system fails, that's it, there is nothing to fall back on and you are just along for the ride. Conversely, with power assist systems you always have control (barring mechanical breakage) but with increased physical effort (maybe more effort than some people can manage). I have never heard of a power assist system failing in such a way that it resisted manual control - it just doesn't happen.
The Z4 may have electric power assist rather than hydraulic power assist but I guaran-frickin-tee you it still uses a mechanical rack and pinion connected to your steering wheel. This is not steer-by-wire. Real steer-by-wire would not have any direct mechanical or hydraulic link between the steering wheel and the front wheels. Same goes for your brakes - there is still a direct hydraulic connection from your brake pedal to all four calipers, and the ABS solenoid has been designed that if it ever failed it would fail safe, ie not disable your brakes.
Somebody has to be able to record them. Don't they? It just may not use a laser recording process like CD-R/RW, so the recording (or pressing) equipment just might not be inexpensive consumer level stuff like we have for CDs and DVDs.
Slashdotters are bashing this idea because it's dumb. PC performance can't be adequatley summarized by a single number rating. There are far too many different parameters involved and they will all affect the way different programs run differently. One program may require a very fast processor but little RAM and only a medicre video card, another may require a ton of RAM and a good video card with only a mid-range processor. Imagine if Car and Driver decided to rate all the cars they tested on a single scale of 1-10 encompassing acceleration, passenger capacity, towing capacity, handling, cargo space, fuel economy, top speed, and comfort. How's that gonna work for you?
So, how good is it for the rest of us when businesses are forced to pay every unskilled "jock from the street" that they hire a wage far beyond their real value as an employee? Doesn't that drive up costs for the business? This results in a greater likelyhood that the busniness will fail (how much is that job worth when the company is bankrupt?) and their products will become more expensive (everyone's cost of living goes up)?
I think most technology workers (myself included) are much too individualistic to ever see much benefit it unionizing. Most of us would rather negotiate on our own terms without letting a middle man in on the deal. Many of us have witnessed the other downsides of unions as well.
Pricing themselves out of jobs. Promoting mediocrity. Antagonising non-union workers / coercing people into joing. Attracting organised crime.
Most of the blown rotaries you'll see are either driven too lightly and succumb to carbon deposits or are run way too hard with lots of boost and a lean mixture. Pre-ignition will always kill a rotary in a hurry.
I'll point out that you're mom's '93 Del Sol probably isn't reving to 9000 RPM or making 120HP/Litre;-). There are 10 year old Hondas out there with that kind of performance/engine stress, but they're motorcycles and they very rarely go 10 years and/or 100,000 miles without major engine work.
I hadn't heard about problems with over-revving the Renesis, but I do know that the 13B in my 1986 RX-7 was reved to the limiter (8000 RPM) almost everyday for the six years I had it and was still running strong at 160,000 miles when I sold it.
I know that rotary engines naturally don't tend to be as fuel efficient as piston engines but I think that at least some of the difference between the S2000 and RX-8 is due to the 194lb weight difference.
Given that the S2000 engine has roughly 27 essential moving parts (crank, pistons, valves, etc), and the Renesis Rotary has 3 (with the rotors turning 1/3 crank RPM), I'll be impressed to see the Honda go 10 years without a rebuild too.
I think the Wankel rotary engine is an idea with a lot of life left in it, considering that it hasn't had 1/10 the engineering time invested in it that piston engines have.
What do you think "wear leveling" means? On newer CF cards they have an internal microprocessor that constantly remaps the logical addresses of the drive to different physical addresses of the drive to make certain that the entire device is being utilized evenly. So even though the OS thinks it's writing the FAT to that same spot on the drive, the drive is really moving that spot around to maximize the life of the drive.
Aren't you assuming that all calls will be VOIP > POTS? What about VOIP > VOIP? There may be no switch. And if they decide to tap your ISP? What do they do when you have an encrypted tunnel to another location ( VOIP > Tunnel....Tunnel > Abu Dhabi > VOIP > POTS )? They won't even be able to tell that you're using VOIP at all.

You may want to save that question for "Ask the Brothers Chaps".

Do a google search for "engine weight" S2000, or "engine weight" RX-8.
I hadn't heard about problems with over-revving the Renesis, but I do know that the 13B in my 1986 RX-7 was reved to the limiter (8000 RPM) almost everyday for the six years I had it and was still running strong at 160,000 miles when I sold it.

Honda S2000:
Weight - 2835 lbs
Horsepower - 240
Engine Weight - 326 lbs
Milage - 20 City, 25 Highway
Weight/Power Ratio - 11.81 lbs/hp
Mazda RX-8:
Weight - 3029 lbs
Horsepower - 238
Engine Weight - 278 lbs
Milage - 18 City, 25 Highway
Weight/Power Ratio - 12.72 lbs/hp
Theoretical Weight/Power Ratio for S2000 with RX-8 engine 11.71 lbs/hp (and likely better mileage due to the lower weight).
