I've actually been to some training sessions for vehicle rescue involving polycarbonate and/or lexan windows. The definitely do not 'pop out' of their holders. You can partually crush a car with one of a window like that and it will only make the window bend. The best tool out of all the tools we carry on a heavy rescue truck that can remove a window like that quickly in a rescue situation? A Roto-Zip.
Actually, they are called "Thermal Imaging Cameras", and they are cheaper than that. Multiple companies make them, ours are made by MSA. My department just purchased one for around $12k, so they are cheap enough to carry one per apparatus. You can get them even cheaper if you want fewer features. Almost every volunteer department I am aware of has at least one.
Generally they aren't restricted by particles in the air until the particles get large enough to block the infrared. In some situations the we can actually find the victim based upon their body temperature being cooler than ambient, rather than warmer than ambient. Also a good trick with the modern TICs is that you can put your hand on a window for a few seconds, pull it off, and you scan still see the shape of the hand in the warmth on the window.
Check which version of Sun Ray software you are using. If you are using anything less that 2.0, you should upgrade. If you are running 2.0, they (finally!) released a group of patches for srss 2.0. I have seen a lot of the lockup issues with the patch go away.
I highly recommend (If you have the money) Veritas' NetBackup Professional. It backs up user's workstations to a central disk, and they can even do file-level restores by themselves. We use it in our offices for laptops, workstations, whatever. The only problem is that the catalog gets really unhappy if you shut it down badly.
Actually, CD quality compared to the digital masters that a studio have is a big difference.
In the studio, they usually store audio tracks at 24 bit, 96 kHz sampling rate. Admittedly, this can reproduce well above the human range of hearing. However, the 24 bits is important. This is because CD's are only using 16 bit, 44.1 kHz sampling. The additional 8 bits makes all of the difference in the world. The doubling of the sampling rate helps with over sampling, whcih makes the sound cleaner and allows for less compression.
Keep in mind, you won't hear this difference on computer speakers.
Actually, he knows quite a lot about what he is doing, because of extremely studious research and a lot of testing of everything they work on. I have been following their work for the last year, and have been very impressed by what they've accomplished.
They are currently working on two projects, the most impressive of which is a VTVL (vertical takeoff, vertial landing) vehicle, with 4 thrusters on the 4 corners, and a central main lift engine with the cpability to lift one person to really impressive heights.
The coolest thing about it is that all of the fuel they use is (fairly) safe for the environment.
This race has been around since the late 80's, before fuel cells were even viable as an energy source. Nowadays, this race exists to promote creativity and thinking for team and to advance the technology of alternative-fuel vehicles. How much fuel do you think you'd save if your car was super-strong and only weighed 800 lbs.?
Plus, fuel cells produce electricity. If more efficient ways are created of using that electricity, so much the better. I've had a part in a few American-side solar races, and usually, the oil companies want nothing to do with them, since it does have the potential of affecting their bottom line. The poster from Sunrayce '93 was a picture of a solar car driving right by a gas station. To bad the humor was lost on most..
I graduated from college with only a minor in CS, but I had lots of personal experience in Linux. I found a Sun shop that needed help, and they wanted someone who knew at least a little something, but was willing to work their way up. I got in, and now I am one of the three admins..
Long story short, find a place that will let you in as a junior and let them know you want to learn. Any and all experience that you have is worthwhile.

For corporate security, there are emerging some start-ups that I have seen that deal with restricting people's access to the wireless networks. Both of the units I have seen funtion as a firewall to the rest of the wired network. BlueSocket is one of them, and Vernier Networks are the two I've heard of. They seem resonably secure to the rest of the network, but they still don't address the issue of encryption over the air.
I think this war may prove to be much more costly and long that any of the talking head may say, for two reasons: It's going to involve ground war, no matter what, because of the terrain involved. And there isn't a lot of technology to show you who's in a cave on the other side of the next hill. Also, if the U.S. proceeeds in this to the extent I think they may, then there will be continued uprisings by people in neighboring nations, which could very well result in war from multiple sides, which can only escalate until cooler heads prevail.
I want to know why you can't play one of these discs in a CD player w/ optical out, and dump directly to a digital recorder with optical in. The stream is supposed to be pure audio, with no other footprints.
If you then take an audio card with a digital input, and dump directly into an mp3 encoder, what's to prevent that?
The only way that a system like that is any good is if there is still a human being checking all of the 'hits' that the recognition systems gets. Of course, there are still all the people that should get picked up but don't..
I've been involved in three of these races (Sunrayce '95, '97, '99) for one team, so here's some answers..
1. The route is not planned to avoid anything except really steep grades, and even then there are some pretty steep hills. This is because most of the motors in these vehicles are only about 14 hp.
2,3,4. The vehicles carry batteries with around 4 kWh of power in them. What matters is that with the different battery technologies, the amount of weight is different. 4kWh in lead-acid batteries is about 360 lbs., while 4kWh in Li-Ion is about 70 lbs. On a fully charged battery pack, some of the top cars can run at 55 - 60 mph for 3-4 hours. (That's with no sun at all) A solar car is really an electric car with a solar charging system.
5. Actually, no. Most people just stare and point. If anyone actually tried to throw anything at the cars they would probably be tackled because solar cells are really fragile.
6. The telemetry systems are allowed to be on a seperate battery system from the car's main power, because of the power drain issue and because of the way that the power must be disconnected, and still have telemetry going.
7. Theoretical top speed on the most commonly used motor made by NGM is approximately 72 mph. Not fast by most recognition, but when you are lying on your back 18 inches off the pavement, it seems mighty fast.
I have seen / played with a program called ZixMail, which actually does embedded encryption inside of the mailer. If the recipient has the software also installed, it automatically un-encrypts the message and the reciever can read it, no problems at all. Also, if the sender send to someone without the software installed, it relays a different message to the reciever, pointing them to a web site where they can securely read the message over https.
Two problems, though. One, you have to register yourself with the server, because the messages are cached on their machines, and that lets them control how the different formats (direct vs. html) of messages are handled. Second, and especially sucky, the only mailer that I know it ties into as of this point is Outlook.

You glance at the title and see "Oldest patent discovered" and wonder what it was for and who's trying to make money from it.
