ATI cards with component video output have a macrovision restriction for protected content. It will not display a dvd above 480p. So, if you want to scale a movie with the computer and display on your hdtv, you have to run a decrypter program.
You can do it in real time w/ dvdidle, or just copy to hard drive and then play.
Samsung had a small phone with built in mp3 player and 64mb internal memory. I loved it, b/c I always had it with me when excercising. Unfortunately, no one else did, and they stopped making those phones.
runs on windows. records on pvr250 and 350 boards using hardware encoding. decodes on allinwonder w/ hardware as well. the epg data is provided and is free. the ability to customize recording preferences is awesome. it is easy as heck to set up. you can use the computer for other things as well. the just get a tivo idea is fine, but I also use the thing for scanning, storing, and serving digital pictures, listening to music, burning cds, mp3 discs and dvds, browse the web, etc. Also, although the original mp2 stream would be better, the board does a really good job of encoding from my cable feed.
She didn't specify what the theoretical weight of the cloud was, but it was around the weight of air, which it should be, because it is floating.
Missouri is 88 mi^2 = 2.7e8 m^2 w/ a 1 mi high cloud and the density of air, this gives 80 million elephants. She calculated 40 million. Close enough. Using the density of water would tive 80 trillion elephants.
These things obviously aren't designed to do professional editing. they are designed to take movie clips along on plane rides and such w/o lugging a laptop. Put a hard disk into it like the archos players, and you have a usefull movie watching platform that fits in a large pocket. Put a good organizer into the archos player, which will probably come, and I'll buy it.
For all those replies modded at five that complained about a terrorist being able to take down a plane w/ a Nokia or the system requiring everyone to opt out, simmer down. It's obviously not a big safety problem, and if you plan on taking a plane down by flipping on your phone, you will waste a lot of time flying. Think of how many calls would be going on if they allowed it, though. There would be at least 30-50 calls going on during every take off and landing in the country. That's a lot of calls that they are stopping w/ the current policy, which obviously works.
One could easily shoot the cable rather than the baloon. You could walk up to it Matrix style, yell dodge this, and shoot, or sit back a couple hundred yards w/ a bag of peanuts and a rifle for the afternoon.

Water Flows Uphill

You can tell by the wave pattern that the water is flowing down the ramps. How *dumb* does he think his viewers are??
It's one thing to use a calculator to get an answer. It is entirely different to play an educational game or do workshops on the computer. As for the workshops, I can't imagine that they are that productive. All they can do that paper can't do is adjust the difficulty level based on performance. But hey, we do that anyway, right? When we study, we skip the questions that are too easy for us and move on to the ones that challenge us, but that we can figure out. As for the use of calcs on exams... I've taken many exams at top 10 universities in undergrad and grad engineering. For most of the good exams, a calculator would be useless (graphs or no graphs). Usually, a computer would be useless too, b/c the point was in figuring out the gracefull solution or approximation rather than grinding out some big ass calculation.
Most of these "5" replies are about terrorists using airports, beds, water, etc. Freaking relax! Airports are being secured as much as possible subject to cost / inconvenience constraints. Water supplies are gaurded and tested against terrorist attacks. Now someone wants to secure WiFi as much as is reasonable subject to cost / inconvenience constraints. Big fucking deal. Sounds like a good idea to me. It helps to be able to track viruses, which do cost money, b/c most users are ignorant about computer security.
I used Red Hat from 1997-2001. It replaced Win 95 for stability reasons. It was great for writing a thesis (LaTex), numerical programming (xemacs w/ F90), email, web, etc.
I got a new job in an office environment, and found visual basic w/ excel very useful for creating an application that other people have to use. Win2K took care of stability (for my purposes). Price isn't much of a concern, since it is minimal compared to the cost of my time. Document sharing editing is much easier when all are using the same setup.
At home, I use Win2K, b/c it had much better support for my AllInWonder card when I got it. Also is more likely to be plug and play for all of the gadgets that get plugged into it.
Last time I used Star Office, it was version 5.2, and it choked on several functions and graphs. Does anyone know how comprehensive the conversion is? For example, what percentage of functions are available. Are custom functions handled at all? Do charts reproduce acurately?
I worked in a lab where the intensity reading of each pixel was important. We used scientific grade equipment, so that we could set the sensitivity, offset, and correction.
If you are interested in measuring the intensity of each pixel, read on:
First of all, I would think that a consumer camera with automatic exposure control would automatically set the gain (or sensitivity to light). You would need to be able to turn this off.
Secondly, the offset has to do with black noise (or error due to thermal energy within the ccd). On the camera's that I used, it was around 5 intensity levels out of 256 on an 8 bit camera. There is not a need of refining this on consumer equipment, so it probably doesn't get much better than that. You can buy cooled camera's for getting rid of this, but you want it cheap so this is not a great option. You could try cooling the camera w/ liquid nitrogen. I wondered about doing this myself. Alternatively, if you are taking images of something that doesn't change in time, you can take multiple images and average them. The black noise of the averaged image will decrease as the square root of the number of images.
Thirdly, the image correction -
Most consumer equipment uses a gamma correction curve b/c of similarities w/ film and video. Look it up if you don't know about it, it is interesting, and useful for taking pleasing photographs. For scientific purposes, though, you probably want a linear response. This will give you a constant sensitivity to light changes.
The last thing you should be concerned with it changing conditions / response with time. Some others have noted this. You will need to calibrate the device many times at different times of the day to make sure that changes over large times are reasonable. We utilized a calibration during the experiment to reduce this problem.
As for image formats readable by mathcad / matlab, etc. That sould be fairly easy once you get the device driver settled.

It didn't have a bloated OS either.
are the copys to pansy to put a chip in their finger? it seems much simpler.

Any phd in fluid mechanics can see that. Jeesh.
