They must do a spectral analysis of the 'noise' and look for peaks at local oscillator frequencies corresponding to local stations and standard intermediate frequencies.
Of course that works best in high traffic areas.

Wouldn't it be getting the local oscillator? That would need to assume a standard I.F. Its many years since I've played much with the internals of radios but are standard I.F's still 455 KHz for AM and 10.7 MHz for FM.
I can believe all that, of course, although it makes things a bit backwards in the sense that busy times when speeding is more likely to be a danger is the time when you are least likely to get a ticket. Why do they bother using the radar or laser at all if they really can't respond to the readings?
If a few people wanted to protest or make a public statement about something, I wonder what the effect would be in a situation like that if a 'moving block' of cars across all lanes slowed and held the trafic down to the legal limit. Not exactly a popular move but depending what you were trying to 'say' it would be quite effective and I doubt that the police could do much about it.
I agree with others that the problems you mention are very real but not really the fault of Access. Access is really two products. The Jet engine and then all the front end forms, reports etc.
I feel like I need to give MS its due praise. It was really Access version 1 that got me started on 'real' databases and I think generally improved the world of desktop databases. Before that I was fiddling around with dBase, FoxBase, DataEase etc which didn't do SQL well or at all. Programming involved lots of, 'set the index, move the record pointer, lookup a related table' kind of stuff. Then along came Access with SQL and enforced referential integrity, queries (views) etc. It was a big step forward and lead me comfortably into 'even more real' databases.
One of the little hassles of life I struck when moving from New Zealand to the US is the greater effort required to empty my pocket of coins. I'd never seen those little boxes of pennies on shop counters. In NZ we gave up our 1 and 2 cent coins long ago and nobody seemed to suffer much. In the US this is the subject of a raging debate. Change (no pun intended) doesn't come easily here. In NZ we also have $1 and $2 coins and prices are usually inclusive of tax so there are fewer oddball amounts to pay.
Also, if anyone knows of any projects (with source available) written in PHP that are designed well, I would be interested to hear of them. I looked at a tiny bit of PHPMyAdmin's code just for kicks and was horrified. But that's not a valid judgement by any means.
ezPublish 3 Very impressive with a choice of GPL or commericial.
I agree that many popular open source PHP apps have a pretty face but are painfully ugly below the surface. Most that I have tried still need register.globals = On.
I'm a Kiwi (New Zealander) living in the US. Some funny things I've noticed between my english (basically British I guess) and american other than spelling and general hood / bonnet, trunk / boot or the meaning of fanny type stuff:
I might say "I couldn't care less". Americans say they "could care less" but mean the same thing. A negative seems to be lost somewhere there.
If I'm sick I might be "in hospital". An american would be in "the hospital" even when nobody knows which one.
"All set" is one of the most frequent expressions I hear. I might say it if I'm ready to go somewhere or start something They say it to mean a general "okay".
The only time I've ever really been caught out by the language was with "entree" in a resturant.
Yes, prepaid can be handy. I got a Verizon prepay for emergencies about three years ago when the minimum payment was $15 per 60 days or about $7.50 per month. Once everyone was hooked, the minimum became $20 and then $30 per 60 days. I couldn't find anything better at the time so I've had it ever since and now have several hundred dollars and a ridiculous number of minutes available. If I'm a day late recharging it, all minutes disappear. I must check out Virgin.
Many years ago I remember reading a British electronics hobbyist magazine which had an article on how to build a metal detector. There was a warning that before using it you needed to go to a government office and get a pipe finders license.
I live in the US and a problem I often hit is companies who refuse to ship to a PO box. This is a real PITA for someone who doesn't have an easy place to receive UPS or FedEx packages during the day. I find the PO quite convenient and cheap especially for small items.
If I reluctantly agree to UPS or FedEx then I sometimes have another problem because my credit card statements go to my PO box and some online companies don't allow different shipping and billing addresses.
The big names (eg Amazon) seem to be smart enough to solve both of these but lots of little ones don't.

My solution to this is to look for a "Virtual Server" account. This is where you have complete control and can therefore install your own PHP. Its also much more secure. If you shop around, the costs are now not much more than good quality standard shared hosting.
I've recently started developing in C# with VS.NET. It is very cool. Even the visual database wizard thingies are useful time savers if you are careful when and when not to use them.
A tip that wasn't immediately obvious to me as a beginner: To use the visual db tools in your non-form classes, inherit the class from System.ComponentModel.Component (or select 'Component Class' when adding a class from the menu). All the examples in books etc seem to only show them being used with forms which is bad for separation of display and logic.
My only real complaint: Why is browsing the documentation so slow? I know its huge etc but it seems like it needs a better indexing system or be in something more like a real database.
Another bit of useless information: (6 more and we'll have a byte)
I'm told that it is illegal for a restaurant to sell raw fish within the city of Manchester so there's no Sushi. The stuff in the mall foodcourt is partly cooked.
There is a famous photo of Soviet soldiers waving a flag over the Reichstag in Berlin, after their army had taken the city in 1945. The official photo was touched up to remove the multiple stolen watches on the arm of the flag waver.

many of the roadways in EZ-Pass areas have average traffic speeds over the speed limits
How can that be allowed to happen?
Have the police just given up enforcing the speed limit in your country.

Just follow the white rabbit (IP address) and you will eventually get to the owner.
How useful is the IP address in headers if it points to a wireless network at Starbucks or McDonalds or an insecure private wireless net.

There are several promising PHP frameworks in development.
Ports of Struts
PHP.MVC
Phrame
And ezPublish 3 which is primarily a CMS but can also be used as a general purpose framework.
IMHO for one of these to really take off (like Struts) is what professional PHP development needs.
