General failure on a UAV that is big enough to crash into a house and kill people would require one of the following:
1) Failure of redundant navigation systems (GPS/INS/photogrammetric navigation) 2) Failure of redundant power supplied to aforementioned navigation systems 3) Failure of redundant computers storing course data and mission planning
Generally, if any one of these has occurred, its because the aircraft has been shot at and is falling to the ground in several pieces already. "When a plane fails" is an oversimplified statement; the window of failures that must occur for the plane to on the edge of loss of all flight critical systems is very, very small. Flight critical systems are usually triple redundant, mission critical systems are usually redundant. If something happens to an aircraft that defeats flight critical redundancy, something else Real Bad happened to that aircraft.
Yes, text displays in today's environment. The vast majority of servers don't need to have a bunch of X applications on them. Its a waste of resources.
You've got your computer over there, and I've got my computer over here, and I have a looooonnnnggg series of tubes connecting my computer to your computer. Your computer has your bank account information in it, so through this long series of tubes, I go into your computer and take your bank account information...
A friend of mine had a windows box that had a virus which corrupted IE, but I was able to open a command line and use ftp to obtain a copy of firefox so I could get an antivirus program onto the box.
I have a Core2 Duo machine running a basic configuration of XP. Its quite fast. The only time I've seen it get bogged down is when it has to pull calendar information from Exchange, and that's not the workstation's fault.
That having been said, I'm perfectly happy with my dual P2 running NT4 you insensitive clods!
I know its not popular here, but if you RTFA and pay attention to other news sources, you'll find out that the NSA has modified Obama's Blackberry to the point that they are satisfied with it. Good enough for me.
This is the worst written summary I have seen in ages. With all the unit conversions, I wonder if this guy is a former engineer for an old NASA Mars probe team...
When I lived in the UK, I had a Vauxhall Zafira SRi CDTi. Its a 7-passsenger crossover minivan thing, with a 1.9L turbodiesel engine, and a 6-speed manual gearbox. I got 40 mpg (US gallons, I did the conversion) out of that monster. Throw on better crash ratings, more features, and an easy to work on engine, and you have an all around decent car. Oh, and its *American.*
And my friend's Ford Mondeo...50 mpg, and its bigger and safer than the Corolla.
There are a fair number of Japanese cars in Europe, but you're more likely to see American cars there.
At a very large defense contractor we had 9/80s. I'm not a huge fan of them. Now, at the aviation and electronics company I'm at, we have regular 5/40s with an unofficial hour of flex time. I live about 30 miles away (all highway driving though) so after a 30-35 minute drive, I get to work around 7:00-7:30am and leave 4:00-5:00pm. I've only had to work late a couple times, the rest of the time I can just go home at the end of the day, no questions asked. If we are planning something that is going to run late and should be checked on, I can take my laptop home and VPN in, although that is a rare instance. Its the least stressful job I've ever had. We even get to carry over up to 14 weeks of vacation time from year to year. We get a staggering amount of job applications as we're also the most profitable company in the metro area.
"Since they're so lightweight and small, there's no real chance for them to survive electromagnetic weapons (hardening costs weight)."
Since they're so lightweight and small, *you never see them coming.* Most are made from composite materials, powered by electric motors. Even at a few hundred feet away, you'd never see or hear most small recon UAVs. If you don't know its there, your countermeasure weapons are irrelevant. My personal favorites are the AV Raven (fits in a backpack, simple assembly, then throw it to launch it) and the AAI Shadow. The Raven is electric and almost completely silent. Once its just a few hundred feet away, you can't tell its there. The Shadow is bigger and gas powered, but from a mile away you won't see it, but its operator will have a clear view of your face. These aircraft cruise at 4,000 feet or higher, even if you can see it, good luck taking it down with any gun.
For the record, I've done a lot of aerospace work, including UAV design and UAV flight testing with the Air Force and Army as a technical consultant with a major UAV consortium. Until you've seen these aircraft in action, don't claim its so easy to take them out of the sky. It won't be civilians taking them down.

Let the GPS fail, the inertial navigation system will take over and navigate back to base. No big deal. Heck I did this years ago in school.
But that would require knowing something about aircraft and UAVs and not screaming about how the sky is falling.
No, its got a cooler acronym, RAVEN: Redundant Array of Very Expensive Not-disks-but-some-silly-stack-of-flash-memory-chips.

The resistance of the installers made it more difficult to conduct business. *ducks*

IMO.
Those three letters are what make the difference between your reality, and actual reality.

You say this, and I imagine a Cessna Citation business jet armed with comically large bombs that it drops on scientists houses.

Just try snarfing and decrypting CDMA data. Good luck with that.

Your Corolla's mileage blows.

"That and the mortality fail-safe."
Is it bad that I read that as "That and the *moriarty* fail-safe"?

RENT?! I wish we could have done that. We had to buy them from the bookstore for $30, and then we weren't allowed to sell them back.

If you can smell something outside the outside the cabin of a pressurized airplane, you have bigger problems than being offended by the smell.
