Aj the laser show guy on the worlds largest HD TV Screen.

 Aj Seabeck of Stellar Designs on the worlds largest HDTV Screen at Dallas Cowboys stadium.

He's on tour with the StarWars in Concert series and the show's come to Dallas.  Such a long way from such beginnings as the A/V nerd of Clifton Senior High school.
The massive display weighs 600 tons, is 180 feet long and 72 feet tall. It's made of 10.5 million LEDs.  13000 square feet display was installed back in May of 2009.

California poised to ban big screen TVs November 4th.

I do not necessarily agree with this, just something that arrived in my in box.
I think setting power consumption standards is actually a good thing. Don't know what levels they are actually talking about.

California poised to ban big screen TVs November 4th.
Make your voice heard! Take Action!
On November 4, the California Energy Commission (CEC) is set to pass new regulations that will limit the sale of big screen TVs in California by requiring that the products meet an arbitrary energy use limit. The CEC's regulation would effectively ban the sale of 25 percent of current big screen TV models and later, 100 percent of plasma TVs larger than 60 inches.

For less than the amount of energy of two light bulbs-- which is typical of today's TVs -- the CEC wants to decrease consumer choice, destroy jobs, and stifle innovation. There are alternatives to these regulations that will achieve the same or better energy savings without the added costs to the California economy.  We encourage you to learn more, and then tell the CEC that you don't want state regulators to decide what TV you can buy! Thank you in advance for your willingness to get involved.

"Lifeblogging" Camera Enters Mass Production

FROM: Slashdot

"Remember Microsoft's camera to be slung around the necks of people with Alzheimer's to help them recall where they'd been? A version of this device will now be mass-produced by a UK firm, Vicon, which obtained a license from Microsoft to manufacture the camera. It is worn around the neck and takes an image every thirty seconds, or in response to its light sensor, accelerometer, or body-heat sensor indicating that something of interest may be happening. Until now only a few hundred had been made for research, which showed they can genuinely help people with memory problems. The new version will be marketed to Alzheimer's researchers this winter, and to consumers for 'lifelogging' beginning in 2010."

California appears poised to be first to ban power-guzzling big-screen TVs

California appears poised to be first to ban power-guzzling big-screen TVs
The influential lobby group Consumer Electronics Assn. is fighting what appears to be a losing battle to dissuade California regulators from passing the nation's first ban on energy-hungry big-screen television

The most amazing thing is that they do this with their CLOTHES (not holding up cards). they have a jacket that is one color on the back, one on the front, and that they can open or close to show a third color shirt on the inside.

save RTMP streams as raw FLV's

If you've ever needed to download video that's distributed in a Flash application, you may have encountered a scenario where the video is being streamed via RTMP instead of progressively downloaded over HTTP. Luckily, there's application called rtmpdump which, as its name suggests, is able to dump an RTMP stream as if you had downloaded a standard FLV.

After downloading and building the source, you can save the contents of an RTMP stream with the following command, replacing the RTMP url and the desired output file name:
rtmpdump -r rtmp://hotname[:port]/path -o output.flv
The program is distributed with a Perl script called get_iplayer, which apparently used to be capable of quickly finding Hulu streams and passing them to rtmpdump, but it looks like this feature isn't currently working due to a recent Hulu obfuscation switcheroo. My fingers are crossed that this will be available again soon, but until then, the tool is still useful for pulling content from RTMP urls that you know about.

Worlds Smallest TV - Dec 1965

from Popular Science - Dec 1965
"Here is the results of Westinghouse engineer's work with micro miniature circuitry and components: the worlds tiniest TV set. The ultimate in compact receivers stands 3½ inches in height and is hardly 4½ inches long.  It's picture tube is only 1 inch in diameter - about the size of a quarter. You'll not be able to buy one, it's being tested for applications in military and space electronic microcircuits."
