If there is no oil export from Iraq, then WHY did they bomb the
ships in Basra yesterday?
It is the US exporting Iraq oil, the profits go into Cheneys
pockets, he pays tax, and that tax is used to buy weapons, bombs,
to drop on Iraqi civilians. [snip]

The current Iraq oil export rate is 1.6M barrels a day (most of
which leaves by ship from Basra). At $20 per barrel on-the-ship,
assuming 300 days/year, that's 9.6B per year. A short time ago
congress approved $87B to pay for added costs and reconstruction
in Iraq, and that was the 2nd large budget outlay. So clearly
oil $$, even assuming we kept any of it, wouldn't pay the bill.

When the $87B was argued, some in congress said we should keep
the oil money in partial repayment, but the administration said
this would send a wrong signal and that idea was dropped. After
all, at only about 10%, why make an ugly issue?
Awareness, bombing civilians for their resources (and control of the
regio) IS ugly.

Yup, it's been active for years now. A friend builds the flash units
for it. BTW, they have a similar system active on the Hume Hwy (Syd-Mel)
to fine speedsters in cars - I believe there are six points and a simple
time-over-distance measurement.

Its a great idea - I think we should do it over here (NZ). Car lovers always
whinge about speed control, arguing its crap drivers who are the real
problem (they are). Unfortunately their solution is for everyone to suddenly
become brilliant drivers, alas an unlikely proposition. Ideally, people
shouldnt be allowed to drive at all.....

My sister lives in Melbourne, and tells me that the traffic lights have 2
cameras - a red light camera, and one which gives you a ticket for speeding
as well (if light is red, speed limit = 0:)

Melbourne had red light cameras in 1987 when I first visited there. I
think red light cameras are a peachy idea PROVIDED they aren't fudged
to generate income, which they are here in a suburb, Mesa, AZ. If I
ever get such a ticket I'm prepared to trash the city in court. I
almost pray for such a ticket... it would be so much fun to collect
damages from the city for running a fraudulent scheme ;-)

The San Diego system was thrown out because 1) the company running the
cameras was paid based on collections 2) they tweaked the yellow light
timing on some intersections to boost income.

There is a new system operating now, supposedly free of those defects.

OTOH, if the fines were in the form of a mandatory remedial driver
education course, we might get somewhere. The guvmint shouldn't be able
to just pocket the money; it should directly target road safety and in
particular the behaviour of the offending driver.

The old system is still in use, but yes, some cameras will issue two
tickets. You won't get a speeding ticket alone though, as they would
get too many photos with multiple cars in the active zone. I haven't
heard any complaints about this system being "rigged", BTW. It's the
roadside snipers that cop (and deserve IMO) the flak, for their
arbitrary taxation.

Some bright s.e.d person should come up with a radar speed *imaging*
technology which divides the photo frame into say 12 zones (3x4), with
a speed reading for each zone (narrower beam angle required). Then the
tickets could be issued to one car in each zone.

Probably our local stores are not using inventory tracking device
tags, yet. But when they do, my concern will rise. Jim, how much
range improvement do you imagine could be achieved with these tags,
or with next-generation tags, if that was the technical challenge
placed in front of you?

Thanks,

Though not directed to me, an interesting question. I don't design
RFID tags; however, I design RF transceivers. This I know from
experience is possible:

~400 MHz, 400 uA continuous receive
sensitivity = -129 dBm
packet size: 24 bytes
raw data rate: 1700 bps
range = 1.5 km (perfect line-of-sight not required)
Tx peak power = +13 dBm
Quiescent (off) current < 2 uA.
size = 2.5 cm2
cost < $5.00

There are power saving modes for sampling the band and responding.

Of course, the above range is only possible with a reasonable antenna,
such as a half-wave dipole. Very small antennas will reduce the range.
For example, a cheap, -2 dBi dielectric "patch" (3.5 cm x 3.5 cm) will
only achieve a reliable range of 850 meters.

I guess an active tag could be built with the above. One of our
customer's applications uses 2 "AA" alkaline batteries. The device
must last 5 years of "normal usage" on 1 set of batteries.

I have been looking up information on the EPC (RFID spec) I saw
elsewhere in this thread. Where are some good references?

dont forget the bell curve though - stupid or arrogant (ie Im a good driver,
how dare you tell me...) people are hardly likely to learn. Here in NZ
statistical analyses have shown that a significant portion of the
drink-driving problem is about 2,000 INDIVIDUALS (pop. 4E6). Cops now
actively target these people, as many are disqualified drivers

arbitrary but voluntary. I choose not to pay, and accept reduced fuel and
vehicle maintenance costs as an unfortunate side-effect. I have done
numerous tests, and driving at the speed limit for 2-3 hr trips will cost
perhaps 10-15 minutes (c.f. speeding +20% where practicable - most NZ roads
are quite skinny and windy, and there are invariably small towns etc) -
hardly worth the bother really. Commuting in Auckland, I frequently am
passed in S.Ak by speedsters weaving in & out of traffic, only to catch up
with them further along.

surely image acquisition/tracking software should be able to do
this.....computing horsepower is cheap (imagine a couple of PS2's or XBOX's)

Whatever happened to reasonable spelling, some punctuation, and a modicum of

Paranoia! When the Nazis marched through Europe, they used the local
lists of gun owners to find their first victims. High tech for the times.

The next invader will use GPS, cell phone, and RFID technology to find
the undesireables. Beware!

Granted that there is no accounting for a lot of what they did, I don't
see the point unless it was simply to confiscate the weapons. Many of
the hand-gun owners would have been of a similar political bent.

That should show up *everyone* as an 'undesirable'. In any case, who
(NOT whom) do you expect to invade?

The list of "undesireables" would be matched to the phone lists and the
GPS would guide them to them.

And who will be the invaders? Only time will tell. America's century was
the 20th. Will the 21st century see the rise of an Asian power?

The 20th did, and look what happened to them.

Homeland Security, of course.
