You didn't get far. Only your second paragraph and already a blatant error. The TV Band/whitespace Devices broadcast ON channel (i.e. 13 through 51), not between channels. In fact it says that right in the article.
Did you bother to read the linked article? Let me help you out some:
ROSE: TV stations need licenses to use the airwaves. But the FCC wants to open up the so-called white spaces between channels so that tech companies can use them without a license. Genachowski says its the same approach that worked 25 years ago.
Unless you think the between there is wrong, but that is exactly what this person who works for a company that designs devices currently using this method says.
>>>between channels 1 and 6 there is a unused band of 14 khz
No. Not unused. It's occupied by various wireless services like police radio. Also 14 kHz isn't anything to get excited about. That's equivalent to a single AM station, and AM Digital Radio only broadcasts at 30 kbit/s...... slower than dialup internet. Completely worthless in the modern age. THINK.
I was speaking of the gaps in the bands of 802.11, if there are police radios up in the 2.4 Mhz range, that would surprise me greatly, as they wouldn't be much use. As to the speed issues you raise, the TV band with even a 14khz bandwidth is still pretty significant when you aggregate several of these bands together. As I am not a EE, and since I don't see you mentioning anything about you working on this project, but the people working for the FCC who are trying to nail out the rules for this are mostly EEs, I imagine they have already thought about these problems pretty heavily.
Actually, what he put down is quite accurate. If you live in Baltimore, you can actually receive the signals from all four of those markets. When they plan the TV stations, they take and draw a circle around the transmitter on a map of the size of the broadcast range for the particular channel, when circles intersect, the people in that overlap area won't receive either station as they will interfere with each other. As all those cities (except maybe harrisburg) are within 50 miles of each other, the overlap areas are pretty large, so the markets have to cooperate on channels.
as I have seen you railing and railing on this over the whole thread, I decided to reply to this post. You obviously live in the same area I do, which is rather interesting, and you are posting on Slashdot, which means you are literate. I am a little baffled why you rail against this technology without even reading about it.
These "wifi routers" are working in the white space between channels that was freed up due to the digital conversion, due to the way the channels are allocated by the FCC, when the digital transition was accomplished, each channel needed less bandwidth. Think of it as channel 45.5, not as 45 and 46 are losing their license. When the channels were analog, there was a gap between the channels in order to prevent interference, with a digital broadcast, interference is less of an issue, and this area of "do not use" is now free, the best way to visualize this is to look at a chart of the wifi bands used in 2.4 Mhz:
if you look at the chart, and the source material for it a bit above, you will notice that for instance, between channels 1 and 6 there is a unused band of 14 khz, if you collected the bands between 1, 6 and 11, you now have 28 khz. When speaking of the TV channels, look how much possible bandwidth is available now that the gaps are no longer needed in the TV frequencies.
Hopefully this post allows you to understand what the FCC is doing, because everything I have seen you comment in this article appeared to be complaints due to lack of knowledge of the subject. Maybe someday we can meet up for beers.
Except that the DDoS was in response to a DDoS of tracker sites on the web. If Anonymous is guilty of a crime, then so are these Orgs for doing the same thing.
I know you are joking a bit here, but there is actually a dead finger test that is used now in many biometrics. Your finger actually changes some when there is no longer blood flowing through it, and even a simple temperature measurement can pick this up. Also, often they will include some kind of vein detection.
I was going to link to some articles but was unable to find them.
How do you suppose they program the unit for people with different length legs? Or people with limited range of motion?
There are many uses for software updates, unfortunately, there are still also reasons against. I was just mentioning that it is entirely possible for there to need to be updates, and some reasons why. Why would you make everyone buy a new exoskeleton when a simple firmware update would fix the issue? These legs could cost near $10k, think of it more like a car, you don't throw away your Camry because it has an accelerator issue, you update firmware to correct the issue.
With more and more devices allowing and requiring firmware updates, it wouldn't be so surprising to have to hook up these legs to a computer occasionally to upgrade the control software. This would leave it open to attack in many ways. Many people who bought the movie Avatar complained about the need for a firmware update just to watch the movie, when you have software controlling your leg movement (or assisting, whatever) what is to say that there won't be bug fixes, or even modifications to the software for a persons personal leg gait.
3 When the wine ran out, Jesus’ mother said to him, “They have no wine left.” 4 Jesus replied, “Woman, why are you saying this to me? My time has not yet come.” 5 His mother told the servants, “Whatever he tells you, do it.”
Hell Jesus even made wine. Beer came from monks as it was the only way to safe water. Yeah, Al is big in the bible.
I'm guessing the letter wasn't published because any man who is scared of a president who pulled us out of a fabricated war,
Which was exactly has Obama pulled us out of? I believe we are still embroiled in two wars, one where we were invited, and one that was started on the basis of bad intel. Why people expect that Bush somehow should have been omnipotent and known that the intel was wrong I still have not understood. There have been many very good indications that Saddam had WMD, and with the way the war was telegraphed through the media for a couple months before it happened, there was plenty of time for the weapons to have been moved out of the country.
But Link is Link, he is right handed, what would be the sense of allowing you to change his handed-ness. That's like saying Link should be ambidextrous./sarcasm
Apple is shipping iOS 3.x for iPads and iOS 4.x for iPhones and iPods,
Ok...
so mobile wise Apple is shipping one flavor of the iOS, 4.x
What? you just totally contradicted yourself, and in the same sentence. So you are saying that iOS fragmentation is a user issue, not a device issue, so um, how do you upgrade the original iPhone to the latest version of iOS? There are the same issues here too, so get off your fanboy bus and try to be a bit objective.
ABC, NBC, CNN, and many others. Are you that partisan that you can't see that?
Democrat or Republican, sending reports about peaceful protests is wrong, it goes against the constitution; you know that document that is the basis for our government?
Yup. I said the same thing above here, all manufacturers have issues of this type. I go Dell when I have a choice at work because their support for the commercial side is great. Call them up, and generally the new part is in receiving the next day. I haven't seen anything like it from any other manufacturer. Apple treats you like a moron who shouldn't open the computer, HP forces you to ship laptops back to them, because god forbid I own a jewel screwdriver kit and can do the work myself. Dell is the only one I have found that will have the new part in my office the next day, and a tech on site an hour or two after to fix the issue. Though I usually decline the tech, I generally have more experience then the tech as I remember hooking up computers as old as C64.
Especially hilarious that it is a completely true comment. Mod me troll if you like, it just proves your inability to comprehend past the RDF from Steve...
Every manufacturer has these types of issues, holding any manufacturer responsable for them will only mean you don't buy from anyone. What manufacturer didn't have video cards from NVidia in this time period? What manufacturer hasn't had a bad batch of batteries?

I am Catholic and I thought it was hilarious. So, dumb people will be dumb, it is now +5 funny, so no worries
They make specially designed edging rollers that can be used with poles.
It looks like this kit includes one, but I could not find one on its own online...very odd.
