It's not the surveilence satellites we've got to worry about. It's the communications and GPS satellites that are critical.
Yes, it's possible to replace them with planes over the battlefield. but that uses manpower and resources. It also requires numerous planes to replace the coverage of ONE satellite... Not to mention that, with the right hardware, planes are easy(-ier) to shoot down.
Actually, the Airforce is tasking manufacturers to eventually develop a quick launch capability so that we could replace a downed satellite in less than a month (I believe they said that they would eventually seek 1 week turnaround).
Yeah. That's about the amount of power some of the slant's are producing. There are two challenges in the slant
the cylinder head wasn't designed for high flow and was originally for a 170cuin (2.7L). There are no aftermarket options. Chrysler made a high flow head for the 2.5L 4 cylinder
The crank in the slant is long and only supported by 4 bearings. The 2.5L has 5 bearings. The racers are finding the slant cranks are good to around 400 hp, after which flex does them in and they start to break. They've been talking about ordering custom billet cranks good to 1500 hp; but, they'll run around $3000/ea.
OK, it's true, I've been lurking (or should I say drooling)...
running a NOP draws less power than running a calc. CPU's get warmer (and are happier -- being all warm and fuzzy) when they're doing intense calculation work because they're exercising more transistors (got to keep in shape, you know).
Processor's shouldn't have a shorter life due to usage, unless it's because the cooling fan get's F'd. Having to replace the fan more often will cost you a few $ every couple of years.
For a single (typical) PC, the difference in electrical usage will be a few dollars per year. Given the typical cost of electricity in the U.S., you're only talking somewhere in the $20 - $100 range.
You're more likely to see it negatively affect your sanity; having those fans running at full output all the time.
I find lot's of overlap. Particularly when you find modern cars are loaded with computers (an engine controller, a drivetrain controller, etc, etc.)
In my example, I'm working on a Dodge with an old Electronic Fuel Control computer (carbureted). I look at it and think: "What were they thinking!?" and "I can do better than that!" and out comes the microcontroller programmer and the laptop....
My first car was my Grandma's '72 Duster with a slant-6
If you're feeling nostalgic: Check out slantsix.org -- these guys are regularly running 12's in the 1/4 and a couple of guys are pulling 10's and 11's. Not bad...
There's ton's of overlap. Cars are an engineering piece of art; and, as you're probably aware, most newer cars are full of computers.
I use google as a source of links for information on what I'm working on. Usually once you hit a major (brand specific) site they'll have more links to other useful sites. There are some generic sites (/. style) but they're usually not very helpful unless you're the guy asking "how do I change the oil in my....."
If you're interested in simulation analysis, there are software packages that'll let you see how mods affect performance. The low budget software (~$59) I use is Desktop Dyno If you have money to blow, Dynomation is available (~$600). They're both written by the same people.
My current project is a truck -- I needed something to carry around parts for my projects... I found it's computer to be seriously lacking; and, will soon remedy that = ) BTW, I have painted my PC with a hammered metal finish, to look like a toolbox... Too much?
It's the soluble stuff that's a "contaminant." Otherwise, the stuff was there to begin with. If you lock up the contaminants in an unsoluble form, then the problem is essentially solved. As for the mining of other metals, the same solution applies, except for the arsenic & cyanide that was introduced. This needs additional attention.
purchased in 1988. still works. A little slow (damn 4bit processors); but, I don't do complicated analysis with it -- that's what the 750MHz desktop machine is for =)
You need to change some of your requirements (such as engineers taking files home) otherwise you're never going to be secure.
You MUST have physical security. I can hack any machine I can get physical access to... If the data's encrypted, I just walk out with the whole disk and decrypt it at my leasure in my lab...
Your IT people need to either get a clue or you need to get new IT people.
Finally, hire a reputable security consultant and actually do what he tells you to.
Otherwise, you're wasting your time -- just go ahead and post the files on your ftp server now.
While for the most part you are correct (and I happen to agree with you about this trash) I should point out that some hubs (such as the one I bought for development work) can source > 1Amp per port using an external power supply. I don't plug anything "questionable" directly into my motherboard...
I'm curious... where did you hear Moto was prematurely stopping production on the G4? I'd like to follow up on that. If you have any links, etc. Please post them. Thanks
It's to indicate a reel change -- so the guys running the projector(s) can switch over. It's usually unecessary now since most theatres splice the individual reels into one long film, on a special spool that can feed multiple projectors...

JANITORS IN SPAAACCCeee!!!
Shhhh. Darpa's working on it.
Actually, this has nothing to do with 9-11. US. Space Command has been making this argument since the '80s.
Preparedness, Grasshopper, is being ready for anything which could happen, no matter how unlikely.
What you've said may be true. However, preparedness is about planning for what could happen, no matter how unlikely...
So, they could order commercial images that resolution from 1/2 dozen sources.

It should be possible to build a "stealth" faraday cage. One that blocks EM but doesn't reflect the radiation well.
Most of our test stands run proprietary (and old) DOS software. We have one test stand still running an IBM AT (as in an original AT)

motorola and pic are producing microcontrollers with a built in USB SIE. Just wire it up to a port...
Thanks again.
