Re:Education required for designing these plants?

How Motherboards Are Made

From my second (or third) hand knowledge. Formal education (sitting in the classroom, etc) is not the main point. It really requires studying the problems at hand very hard and constantly tweaking and refining. They may speak lesser English, but they do know to pool experiences from all the displines mentioned in this thread together.
This is NOT to say whoever designed and maintained such a plant do not have education. Most of them have advance degrees. Typical job opening needs a college degree just to get the resume in. AFAIK, the salaries for entry-level engineers starts around US$15,000/year. Not great, but certainly not pennies per hour that some/.ers thought. And the compensation is HEAVILY loaded with bonuses and stock options. It is not unheard of the bonuses being several times of salary for a good year.
Oh, for those who are interested in some certain phone numbers: send some Karma over and I'll see what I can do.
Well, looks like your math is right. But the resoultion of a radar is mainly determined by its bandwidth, not the carrier frequency. i.e. Shorter pulse = larger bandwidth = higher bandwidth.
Yes. See FCC ruling. One of such radars I believe the issue of opening up this frequency for automotive use is currently being debated in Europe, too. There are protected bands around 23.7 GHz for ammonia spectral lines.See this list.
But without freedom, all you enventually get are inferior products! That's the whole idea behind free software and free market and free society. Can't you see what happened to the places where there's no alternatives? RMS might have a personality that is too strong for many people's tates, but he knows what he is doing and he sticks to it. The world may not be a better place if everybody follows RMS, but it is certainly going to be a lot worse one if there no people like him.
I like to protect my privacy, but I hope companies that provides good services to last.
Amazon has been losing money since day 1 despite its huge customer base and shipping volume. If they are going to be around then they HAVE to make a profit. The way I see it, they either have to find other revenue sources or increase the prices.
For the first option, they are already selling not only books but toys, music, and many other stuffs. What else could turn the margin to the postive side? Raise the price will drive away at least some of their business to competitors. Remember the next store is only one click away and there are programs that will automatically check the prices on other sites for you. The customers almost ALWAYS know where to find the lowest price! How much do they have to raise the price to break-even? I don't know, but I think a 5% premium (over their competitors) will probably drive a BIG chunk of their customers away.
I really can't blame them for viewing the customer's data as a souce of income. IMHO, that's their biggest assetts. So if they get another policy out, saying they'll NOT sell your information by default. But if you are willing to let them sell it, they'll give you a 5% discount. So people can opt-in and save a few bucks if they don't care THAT MUCH. The rest could be assure that their data is confidential.
I think it's only fair either to pay for the goods and service or let someone subsidize (and gain access to your data).
How could they (or any software company) lose money with deal like this? O.K., you found (and even proved) that their softwares are problematic. You called 1-800-MS-S*CKS(TM) and obtained an e-mail address to send back the (faulty or not) software. A week later, the compressed file of the upgraded version software arrived at your e-mail box and your credit card was charged $399 instead of the MSRP of $524. Sweet deal, eh? No, wait here is the best part: you don't even have to be the original owner to be able to do this.
A better deal for the software company, I think.
Well, from "pure" technical point of view, there's very little "new" stuff here. The point is to figure out a way to build them cheaply. Almost everything in Astronomy is astronomical, especiall the cost. For example, it will be considered a bargin if one can build the SKA for less than half billion USD. So to use off-the-shelf components is essential. Those dishes may not be the best ones out there, but you will need thousands of them before it is done. So are the LNAs and the Correlators, and the computing units needed. It comes down to MONEY, 100s of millioms of US dollars at least. If you insist on using "cutting edge" technologies, you'll be talking about billions of US dollars.
For each dB of reduced transmitter power, you can have ONE dB more on the antenna gain. The sum has to be less than 36dBm, well, legally, anyway.
You can certainly attatch an antenna with higher gain if you just don't care what FCC or other users of this frequency have to say. But please let me know if you know how to build antennas with 186 dBi gain.
FCC allows 36dBm EIRP. That could be 30dBm (1 Watts) power + 6dBi antenna gain (or 20+16 etc.).
If you are using an antenna with 45dBi gain, the output power should be less than -9dBm. Otherwise it is very possible to F*CK other's communication.
More importantly. This could become a health threat, especially for people who are near the transmitting antenna. Theoriotically, 30dBm + 45 dBm gives you more than 30K Watts EIRP!! Even allow for some spreading, it could do some damage to some senstive organs. Please be advised the 2.45 GHz ISM band is EXACTLY the microwave OVEN frequency. I don't know about you, but I'd rather not been aimed at by this kind of energy.
It is surely NOT legal and potentially UNSAFE. To be blunt, if you cannot derive these two conclusions by reading those instructions for building the "wireless networks", you probably don't know what you are doing. Think twice, no, three times, before you set out to enjoy your "cheap wireless" network. There are things even reboots or re-formats can't fixed.
I like Alpha chips. For number-crunching, they are the best, but their commercial future has been a concern. Intel doesn't have the best chips but they do make A LOT of them. The sheer volume brings down not only the selling prices of the cpu, but also the prices of motherboards etc. Alpha chips might still be the king for FP computations but IBM and Sun have pretty good chips, too. How many High-end chips can the market support? I am afraid that Alpha chips will be forced into a very small niche. People would have to pay a lot more for the same porformance/price ratio if they want alpha machines. If that happens, it will only be a matter of time before Compaq pulls the plug. The key point I see is the volume. How can they sell more to justify the R&D cost? One possibility I saw is to let Aplha chips use the same MBs as AMD's K7s. That has not happened, right? Even AMD has troubles to bring down the prices of the K7 motherboards. Is there a way out?
