I have seen IETF in operation about 12 years and I have worked with industry bodies such as 3gpp - worked on one particular standard which actually went through the standardization process. Standards bodies are supposed to be slow and stodgy, that is their purpose. There was a time when we used to get objections based on corner cases which (we believed) were irrelevant, but, in any case, the objections were made in good faith. I used to enjoy the debate, trying to get another, obviously very smart person to see my point of view. Nowadays we get objections which, you know, are because of some directive from the other guy's C*O level or some legal or marketing directive, which he is powerless to oppose. You feel embarrassed for the guy, because you know that he isn't allowed to change his stance and therefore all debate is immaterial. This is the effect of corporatization.
The working groups are infested by corporate types, from Cisco, Google, Microsoft, you name it. IETF was made what it was due to academics - van Jacobson, Jonathan Postel, Sally Floyd, Henning Schulzrine. No wranglings about patent rights or the need to keep their respective companies competitive edge.
They don't actually 'poll' the the tower, they monitor the paging channel. They do re-register with the network every 30 minutes or so, so as to let the system know where they are. However, this is for a static phone; a phone moving inside an airplane would be updating its registration every few minutes as it went from one cell to the other.
The ringing tone is sent back by the local switch once the remote party's location has been verified and an ALERTING mesage has been forwarded to it. So, it is not entirely meaningless when you hear a ringtone on your phone.
"The alleged tax evasion pertains to royalty payment made against supply of software by its parent company, which attracts a 10 per cent tax deduction under the Tax Deducted at Source (TDS) category."
Basically, Nokia India pays Nokia International royalty for each copy of software that it loads onto the phone - as per Indian IT law, they should deduct 10% tax at source. Nokia claims that this is not applicable to them because they are in a Special Economic Zone and the IT department disagrees.
This is an old dispute and the inflation is due to penalties (Nokia has been operating in India for a long time). It has nothing to do with the Microsoft deal - the whole issue has come to the forefront because Microsoft may refuse to go through the deal if this issue is not settled first.
So the first thing he is going to do is to offshore it?
The entire public transport system in New Delhi was switched over to compressed natural gas ten years ago. A city of 16 million people.
Actually, it has been reported in all Indian newspapers and few news channels. I don't think many people were paying attention, but things might change if deportation all of a sudden became a consideration.
Except that is not how science works. 99% of climatologists can be in agreement with AGW and it doesn't mean a thing. Please don't fall into the trap of the deniers by going down to their levels.
The problem in the AGW science that exists today is that there is no one single experimental result which conclusively demonstrates a prediction of AGW theory (AFAIK, would be happy to be corrected). Verifiable predictions are the heart of modern science; it is very hard (and very wrong) to make the case using empirical data only. Unfortunately, it is not easy to setup experiments in an area like this, so we are looking for predictions of results in specific situations. And we don't have that yet.
Wasn't this the program which caused Lockheed Martin to shut down comsat labs?
God, I hope your message goes through to Mozilla. I am seriously contemplating stopping using firefox altogether on my work comp. It eats 345MB of page memory and completely destroys everything else.
This is why I am increasingly of the opinion that capitalism is dead. The employee (CEO) gambles with his employer's money and walks away with a nice parachute when he is done. The capitalists (share holders) are left to pick up the pieces. They cannot effectively punish the CEO (the board was packed with his cronies anyway, all CEOs somewhere or the other) and he will jump into the CEO's seat in some other company and proceed to ruin that one.
Free speech would be an issue if he had restricted himself to making his own web-page about the subject. But when he went and posted offensive comments on somebody else's tribute page, he crossed the line and became a nuisance.
Multivariable calculus, differential operators, manifolds, tensors and Stoke's theorem
Buy the book by Spivak or Munkres' "Analysis on Manifolds". Multi-variate calculus is a beautiful subject, regardless of whether you want to learn relativity or not. Once you are done with that, you need a higher level book on differential geometry.
Actually, at the old TV spectrum, your signal would bounce nicely of the sky and you could get natural multihop transmission. That is one of the advantages of using OFDMA for the air link, because it is resilient to path variations.
