'How do you diagnose an embedded system that has rendered itself unobservable?'
The way you do this is by having an exact duplicate of the remote system so you can set up a test with conditions as close to those under which the remote system is currently operating. You can then do a series of carefully controlled test solutions to determine the optimum prior to trying it on the "live" system.
This is the way I set up all my production systems and, barring catastrophic hardware failure (self-immolating disks and a router which just folded when its power supply burped) I've had perfect uptime.
(well, ok.. there was that one time, late at night, when I typed "reboot" in the wrong window.. but that happens...)
Re-reading the FAR Part 91 shows that aircraft under 75,000 pounds are exempt from the regulation anyway...
Stage-I (the proper term) engines aren't even built anymore (since 1974). The joke was how loud that little thing is for how small it is (like one could even tell from a lousy.MOV file whether an engine was Stage-I or Stage-III).
Based on the sound from the video, this craft is clearly using a Class-I jet engine. These were phased out of use by all but older military craft (which were grandfathered in) due to excessive noise.
This is the deal with Coppola's wines--they're just ok wines for better-than-ok prices.
Yeah, that's what I thought too until I actually tried one of Coppola's wines..
That sounds flamish, but it's really true. I've got a couple of bottles at home in my basement. They can also be reliably found at Trader Joe's (aka "Home of the Two-Buck Chuck") for a very good price. I don't think Coppola's price-point is out of line for the quality.
In fact, a large proportion (if not most) of the vineyards in California don't produce their own wine - their grapes are sold to various other producers for inclusion in those wines.
I'd hesitate, though, to say that the after-harvest method is more important than good grapes from a good area (for those grapes). While the same grapes, given to different vintners, can produce radically different wines, the quality of the raw material determines the baseline quality of the wine.
That's why I ran to the Rhone! I've been bathing in Chateauneuf du Pape (and surrounding appelations) for the past couple of years and loving every minute of it...
On the other hand, if we rolled that out we'd have alot more decentralized fast networks and the internet could be about connected peers again instead of the consumer/producer model we've got now.
Sorry, but with things like Comcast/Disney going on (delivery + content provider in one), the 'Net is actually going MORE toward consumer/producer. That, IMHO, is a bad thing (and I'm not even going to start to talk about lock-in crap where, if they have their way, you only surf THEIR lines to only look at THEIR content).
Good point. However, in the context of production of ethanol into hydrogen into electricity, the solar energy has already been consumed in producing the raw material (eg, prior to the conversion equation). No matter how you slice it, there can be no "net gain" of energy.
You take Energy Form A (grain) and convert that to Energy Form B (ethanol), then convert that to Energy Form C (hydrogen, plus extra stuff discarded), and from there Energy Form D (electricity). At no point, going all the way back to the production of the solar energy, can there have been a net gain of energy. There is only a loss of usable energy (the energy isn't destroyed, it just doesn't get to enter into the "work" being desired).
2. Converting ethanol into hydrogen and then burning the hydrogen may be far more efficient than burning ethanol. If so, it is possible that each gallon of ethanol represents a net gain of energy.
Just picking a nit here, but where does that "extra" energy come from? I am not a physicist, but I do seem to recall that energy can not be created or destroyed, only transformed.
You invariably lose some of that energy in the transformation from one state to another. All you can do is minimize loss by maximizing efficiency of transformation.
Therefore it is impossible to have a "net gain of energy".
I had a Commodore PET that used a tape drive. And I never labled the tapes. It was very frustrating to LOAD a game, go out for a snack, and come back 45 minutes laters only to find the game wasn't on that tape...
What part of "Economic Litigation" don't you understand?
A company or person with very deep financial pockets can sue out of existence another company or person without such financial resources. It costs money to hire lawyers to do research and show up in court. With a million dollars and a halfway-competent attorney you can bury someone with a thousand dollars and Perry Frickin' Mason on his side.
It's been done countless times before, and it's about to happen to SCO (notice how IBM isn't moving for a dismissal...).

Holy crap dude, you win the prize for Obscure Word of the Week. Have you been reading books again??

Finally I'll have someone to blame my flatulence on besides the dog and my wife (neither of whom are amused).

The U2 spyplane was basically a glider design with a jet engine stuffed into it.
The idea was to have a craft with an overly-large wingspan to be able to fly at the (then) extreme altitudes contemplated by the U2 designers.
No no no.. that's Surly Naussican
Good try, though!

You mean Kunta Kinte?

Darl McBride is a Russian boxer?
Ooos.. that deserves a +1 Funny. Good on ya'!
I'm going to start a cultured-diamond distribution business and call it "DaBrews".
Think I can get by without having a Belgian 9mm applied to my brain?
Dumping into the ocean, you say? Got some GPS numbers for me?

Don't forget to use a hole-punch on the edge of the disk so you can use BOTH sides...

You must come from the rich part of town. I had to make due with my 110 baud. I could read faster than that thing could print to the screen.
