We run into this all the time when doing server administration. For example, one of our developers found that web pages were slower on our new virtual servers. The obvious thought is that virtualization=slow. It turns out that compression hadn't been turned on for those servers. Since he was going over a slow VPN connection, it made a fairly significant difference. Once switched on, they worked about the same as real servers.
Yea , but it was still 'something' related to the change that was made.
The dev may not know all about what was done. All he knows is that "before the change it was fast" and "after the changes it was slow". His only information about the change is that it was new VM servers.
Because of the fact that his knowledge of the change was limited. His observations are no less valid. to him it IS the vm servers that are slower.
You mention server administration , so I assume that you do something tech like as work. When you walk in the door on Monday and there is a problem, do you start trouble shooting the whole system ? or do you first ask "what has changed" and start looking at it from that point ? 9 times out of 10 if something has changed , thats the cause of the problem.
The good thing about this story is about how apple and cisco were able to come together to find the problem. In my experience , cisco is one of the few company's that will admit when its there stuff thats broken. At least once you get through the first levels of support. And duke most likely has a ccie on staff , or a provider contract with cisco to gain access to real support.
1) RF in ( from your cable company ) 2) RF out ( to the tv ) 3) POWER 4) Some sort of data connection. Either phone line or network. The bulk of tivos sold ( Series 2 ) dont have wireless networking built in yet. YOu would need to attach at least a USB type device.
AND there is still a nice long setup process with tivo.. Registering the box.. configuring your channles.. Perhaps configuring your cable box..
Fast switching ?? What do you mean by that.. Every fiber switch I have ever used had a MUCH MUCH MUCH lower latency in the switch matrix then coper. Or perhaps you are speaking of something else.
For you to say that they ware wholly unrelated means that you do not understand the force in question.They are indeed the same basic force.If you really want to discuss how the forces are the same we can do that. For your review here is the link the wiki on EM Radiation. While wiki can be wrong, in this case its should suffice to explain my point of how they are indeed the same basic force.
If after reviewing that you care to have a true discussion on how they differ and how they are the same we can. But please take a few moments to review the subject first.
Now I have no idea how this thread got to this point. MY original post was in response to someone summarily dismissing an anecdotal statement about how his friend was able to detect wifi points. It was not in reference to TFA at all. It was simply in response to THAT posting. I guess you were referring to TFA all the time while I was not.
one problem with that , its not 10k years. Humans have know about radio for only a few hundred. But thats not even the point here.
I think summarily dismissing it would be a very naive and arrogant thing to do.The idea is not as far fetched as you may think. EM sensitivity has been proven in the animal kingdom , Think homing pigeons and there internal compass.Which means that nature, as a whole , knows how to detect an electromagnetic signal outside of the normal visible light range. Why would it be such a far stretch to think that the human animal could not develop that sense ? either by design or a mutation.
She very well may be a crackpot in a tin foil hat.
However , If the chick claims that she can sense a wifi access point , and anecdotal reports support it. Then it warrents further study. We know almost nothing about how the human brain works. Even with the recent mapping of our dna , we still have no idea what most of it does. Why cant some part of that be something that was able to detect EM of some sort. Which has been activated in some way in her and has become resonant at the frequency that the wifi access point is transmitting at ?
Thats all I am saying.
To say "it sounds crazy so it must be" , is just stupid.
Well.. the wattage required really depends on the wavelength. Generally speaking the longer the wave the higher the power. in the ghz range where WiFi is 1 watt is ALOT. Down where most am and short wave stations transmit you can pump out a kilowatt is mid power.
Also the way the wave interacts with the earths magnetic fields determines how much power you need. Right around 10m wave lenghts is when your signal will stay inside the atmosphere as apposed to flying right on out.
But no matter how you look at it.. the numbers he used were several orders of magnitude too big.
Yea.. I agree with that.. im just saying that its not outside what I consider to be somewhat plausible .
Like as an example..
I would need MORE proof of someone claiming to be able to travel thru time , then of someone being able to simply detect the presence of RF waves. If that makes any sense.
It just felt like a project that was trying to discredit apple more then it was trying to really fix things. The fact that they did not tell apple about the bugs they did find before hand , says to me that they cared more about publicity then fixing them. The fact that they included bugs in software that apple has no control over makes me believe that they did not have enough bugs to fill the month. Which could also be the reasons behind not telling apple. If apple fixed any of the bugs they were told about before release they would have had to include MORE non apple code bugs.
What does religion have to do with it ?? and while it really has no bearing on this.. No I am not religious.
My point was that there are things that people can sense. it may not make sense.. but they can. just because you cant does not mean that they cant.
how skeptical one should be as a default is left up to the person. If someone was to tell me they drove a car at 90 mph on the highway , I would tend to trust that they have. if they said they have driven at 250 mph on the same highway I would tend to not.
Being able to simply sense that a radio wave is present is not outside my realm of believability. If he was to say that she could tell if the access point was using wap vs wep , I would tend to discount that. It has nothing to do with religion.
is being able to detect radio waves really that unbelievable ? its simply a form of electromagnetic radiation. your eyes have eloved to detect a small range of the same type of radiation, what we call visible light. Why is it such a stretch to believe that some people could detect different frequency's of the same type of emission ?
Think about it this way. its the same thing as if you were blind , and someone told you that they could see things.It would be rational to be sceptical about that as a default ? Or if you were deaf. Or even if you were color blind. Would you be skeptical about someone that said they could see different colors?
ummm.. your incorrect in your estimation of the power levels of a commercial FM broadcast.
first of all think about what you are saying. 100k MEGA watts would be.. 100k Million watts.. or.. 1,000,000,000,000 one TRILLION watts. Now just for reference , in RAW power usage , a Home in the us may use 100 or so KILO watt hours per month.. so your saying that your local FM station uses.. 1 billion times more then a normal home. So that your local station pumps into the air the amount of power used by 1 BILLION homes in a month , EACH HOUR ?? This is also assuming a 100% efficient transmitter.
Think about the scale of things before you post please.
50,000 watts is a lot for even an AM station. Which is a lower freq and also a different type of emission where the power does help in its transmission distance. with FM power does not help with how far you can transmit. It simply allows the transmitter to over come interference. The FM range around 88 to 108 mhz is a line of sight wave. Its ant hight that sets how far you can transmit.. not the power levels of the transmitter.
1kw is a lot for a local FM station. much more then that and its simply wasted.
Are you SURE its the sound your detecting. It may be that you have no frame of reference and think its sound but you are detecting some form of electronic emission.
I have a friend whos vision can see slightly into the infra red spectrum.She can look at an object and say that looks hot or cold. So I understand how someone can be sensitive to non normal things. Perhaps the OP's friend can simply detect that one range of freqs due to some resonent vibration or something from the one range of frequencies.
I would think that you with your "dog ears" would be one to not dismiss it so quickly.

Target , sunday mornings .. as a matter of fact I just came from my local target , they still had 5 and I watched 2 get sold while I was in the dept.

Three cables ? Even tivo cant do that
.. Registering the box .. configuring your channles .. Perhaps configuring your cable box ..
Even the simplest connection requires 4
1) RF in ( from your cable company )
2) RF out ( to the tv )
3) POWER
4) Some sort of data connection. Either phone line or network. The bulk of tivos sold ( Series 2 ) dont have wireless networking built in yet. YOu would need to attach at least a USB type device.
AND there is still a nice long setup process with tivo
its not "plug and play"

Well .. ummm .. not for nothing .. the MOAB had a few bugs that had nothing to do with apple.
7 .html bug is in VLC not apple software7 .html OMNI web7 .html Transmit ( 3rd party ftp app )7 .html Flip4Mac .. Just that it was not all bugs in code that apple controls. Also , at least for me, they turned me off when the second bug was in vlc and not anything apple.

Nope. At least not according to imdb ( and my memory ) and its quotes section from back to the future.
