A few days ago I had the task of figuring the height of an abandoned broadcast tower. It lost its top section in a storm so the FCC records were useless. My first instinct was to measure the length of its shadow to compare with the shadow of an object of known height. Towers are usually made of a steel lattice that allows a large majority of sunlight to pass through. While the bottom few feet cast a noticeable shadow in the grass, the rest of the tower's shadow faded out of existence. Given this experience, I'm not surprised that you cannot see the antenna's shadow, but can see the building's. One is a lattice of steel that lets a lot of sunlight through, the other is an opaque surface.
USAA's deposit@mobile service is pretty neat. But it takes a bit of work. You need something dark for the background. I usually use a black shirt or jacket. You also need good lighting. You still get use of the funds instantly. I've used their check scanning for years, but I now use the mobile version more often. Feel bad for my old Canoscan, scanning checks was practically the only reason I've kept it.
In many cases, such as this one, there is no need for perfect 1:1 VSWR. In broadcast, you can have several kilowatts, or more, of RF power going into an antenna. A high VSWR can be very bad. When you only need milliwatts of ERP, you can deal with inefficient antennas.
This system will still force our adversaries to build more complex rockets and delivery systems. Rocket science is tough even for the Russians, Chinese, and North Koreans. So maybe in their attempt to upgrade their rockets to bypass our barely working defense systems, they will make even more mistakes than we did, and their rockets will fail all on their own. Based on resent missile test from Russia and North Korea it might just work.
This device was designed for the relatively open space of a farm. In urban environments where this may be used, you will get reflections off large flat surfaces. Constructive interference will create some areas of higher sound pressure than might be predicted by the distance alone.
The last time I voted was on an electronic machine. I forget the brand, but it required a key card, and had a paper tabulation of your votes that was visible behind a clear window for your approval. After approving the paper backup, it scrolled up out of sight. I really liked the system. It was easy to use, prevented voter errors, and provided a paper trail. Traditional paper ballots are beyond outdated, but having a paper trail is still necessary. This was in Ohio by the way, but I guess each county has different election commissions and therefore different machines.
Who ever said our rights are limited by the Constitution?
The Bill of Rights only serves as a last measure against attempts by the government to infringe upon these rights. Our cherished First Amendment, for example, does not give us the freedom to speech. We were born with that right. The amendment simply restricts Congress from making any laws curtailing that freedom. It important to remember that these rights we enjoy are not simply words on some document, but instead are our unalienable and fundamental rights as human beings.
One of the arguments against adding the Bill of Rights, was that the explicit and written protection of certain rights and freedoms would cause some to forget about those not included. Thus the oft forgotten and yet critically important Ninth Amendment declares that:
The enumeration in the Constitution, of certain rights, shall not be construed to deny or disparage others retained by the people.
We do not need some piece of paper or court to tell us that unlawful and secret imprisonment is a violation of our basic rights.
He's obviously one of the drug cartel's henchman with a name like Cruz. He was probably taking pictures to send to all the other drug dealers in the area. The police were being very prudent in this post 9-11 world. Since they were unable to determine his innocence on the scene, the best bet is to arrest him and figure it out latter.
Don't worry, the Chinese got that covered. The US intellegence community would be mighty confused and overwhelmed when the backdoor they put on a 100 copies of windows ends up being installed on half a million PCs.
Loran (90-110 khz) is still operational, but if you want real low frequency navigation, you want Omega (10-14 khz). Omega ceased operations in 1997, but while operational its signals had a wavelength of around 25 kilometers, and were transmitted by 8 stations scattered across the globe. By receiving signals from three stations, am Omega receiver could locate a position to within 4 nm using the principle of phase comparison of signals. This made Loran-C (accuracy better than.25 nm) look damn accurate in comparison. These shortcoming aside, it was the first worldwide radio-navigation system.
Andrew Lack, the chief executive of Sony BMG, discussed the state of the overall digital market at a media and technology conference three months ago and said that Mr. Jobs "has got two revenue streams: one from our music and one from the sale of his iPods."
"I've got one revenue stream," Mr. Lack said, joking that it would require a medical professional to locate. "It's not pretty."
I really love how Sony, of all companies, is bitching cause Apple is making money from their iPods. Sony has never profited from the sale of portable music players have they?
I hope to one day actually see products using nanotubes, but I sometimes feel as if nanotubes are becoming the snake-oil of the 21st century. Promising to revolutionize integrated circuits, create indestructible synthetic fabrics, cure impotence, heal the blind, or whatever other applications someone can write a little press release about. I am almost getting sick of hearing about all this research, call me when they actually are mass producing real products and quit with all this nanotube hype.
I believe that the Morse Code should not be a requirement just to to operate on the HF bands. At one time it made sense, but with today's digital encoding methods, you can have reliable low bandwidth communication on the HF band. Even the ARRL plans to file a petition with the FCC seeking the regulation of amateur subbands by bandwidth rather than by mode of emission. http://www.arrl.org/announce/bandwidth.html
And for all you old timer hams, eliminating element 1 as a requirement for General and Extra Classes does not mean that they are abolishing Morse code. It will still probably be used for decades to come, it just will not be a requirement for those who just want to do SSB or digital contacts.

If I swallow my thumb drive containing all my favorite programs, would they come out decompiled?

Wow, I'm surprised no one posted 1984 yet.
It was only 23 years early.

The FCC stepping up to actually protect consumers? Guess the Telcos need to buy off some more commissioners...
