Actually I think it is done by way of 4-times oversampling the data, giving you a nice automatically quaderature version of the incoming time-domain signal. It's the way the FlexRadio works, a very fast Taylor detector and commutative switch. If you can sample at 120MHz, you can do the normal 60MHz Nyquist sampling required for the 30MHz HF band, and if you can sample twice as fast, the intervening points will actually be the quaderature phase of the complex spectrum. There's an article about it in Gerald Youngblood's QEX on Software Defined Radios.
While I might be inclined to agree, morse code really isn't that hard.
I picked up 5 WPM code in about 2 days. It's so simple it's amazing. If anything, you can memorize the alphabet, just write down what you hear, and translate later... because it's just so slow.
There are whole bands that are CW only, so unless the also relicense them for voice it would be silly to not require CW. CW is very effective when no voice signal can get through either. If you have a one watt transmitter and you're trapped in a strange area, you may only be getting a broken carrier across, but that's enough for code. Plus code takes so much less bandwidth (a precious commodity) than voice or packet or any other kind of transmission.
The Technician class is saving amateur radio, and if anyone really enjoys it and wants HF, they'll put forth the little effort that is required to learn CW.
I got my license when I was 10 years old back in 1994, and no one in my family was a ham or anytihng. I just did it because I enjoyed it. I stopped going to the local club meetings when people like you would start arguments with the obstinant old people about code requirements. It wasn't fun anymore. If an 11 year old (when I got General) can learn 13 WPM code, then so can a 35 year old! So shut up and get your key.
It is my understanding that even if you do not have phone service, the phone line is your house is still wired. I know when I didn't have service I still got a dialtone, but I couldn't dial anything.
I believe the phone company (landline) still has to provide 911 service, even to disconnected lines. So, you could always just have a phone or two still connected to the landline if you need to call 911 and don't want to use Vonage.
I have heard of people who were obviously using their cell phone as a modem, which is not allowed in their ToS.
Sprint will basically tell you to either buy their real data connection with those Merlin cards ($100 a month I believe), or pay for all the bandwidth you used (1 or 2c/kb I believe).
I would not recommend going the "PCS Vision through Cell Phone to computer" route unless you're very courageous/stupid.
If you absolutely have to, and don't want a local line at all, use the $100 Sprint Wireless Data modems. You can actually pull about 12-13 k/s typically (for me at least) off of them, with about modem latency (200-350 pings).
Well really, even receiving signals causes you to generate a signal. The VFO, or whatever kind of fixed-oscillator that is being used to tune and receive the frequencies that the GPS satellites use causes a sort of EM leakage that is detectable.
Is this a problem? Probably not, but just so you know... receiving does generate an electromagnetic field that could theoretically interfere with the most poorly designed electronics on the planet.
I hate the RIAA as much as any other geek here seems to, but I work for a University and I've seen these Mediaforce / BSA complaints.
They arn't 'snooping' on you, you're publicically making the information available. Let's face it, 99% of every complaint that we get here is legit and it's copyright infringement. Whether you agree with copyrights is another issue, but it still remains that it is really illegal. They don't have to seek you out, you make the information available to them.
The letters don't require any lawyers. The letters get sent to the abuse people who send an email out departmentally and ask for them to check on the file sharing. So at most is caused some sysadmins a headache and some questioning of end-users.
Is anyone compensating the RIAA for the most likely others hundreds to thousands of legit copyright violations that they have probably forwarded to Penn State? No.
People here always seem really one sided. The software is pretty dumb, you'd think they would at least put in his song names to further narrow down the search patterns, because Usher*.mp3 is pretty generic (and that's Mediaforce's problem, not the RIAA).
Like I said, they have to deliver it. But if you were to live in a place where there is a rural carrier in his little car, what do they do when they are not able to deliver it in a standard manner? What if there is no room in your mailbox? Do they throw it on the ground, store your hundreds of pounds of mail at the post office in the hope that you will come and get it?
I wonder, how does the USPS deal with a person who gets that much mail? Obviously they have to deliver it since that's their whole purpose, but I know the little mail truck that comes to my house probably couldn't fit a few extra hundred pounds of mail. And the poor mailman, and the mailbox itself.
It was my understanding that you can enable a packet sniffer and not give it an IP address. If it has no IP address, it certainly won't be responding to port scans. You still do get a light though, you're right. All you have to do is 'ifconfig eth0 up', viola, no IP. I have a box at home running Snort like this.
But, if you have a switched network, the thing won't see anything useful anyway. Somebody would have to break into a closet somewhere, put it on a port, break into the switch, and mirror traffic to the thing (which will most likely break it's bandwidth barriers).
I have to hand it to 3D Realms, I have to respect a company that can focus on putting out a quality product no matter how late it may be. I know a lot of companies don't have the resources to do such a thing, at least 3D Realms does.
It's not like anyone's productivity has been hurt by not having this game available and I think the wait will finally be worth it as it will most likely be a killer product when it is finally released.
Also have to pat them on the back for having such a humorous attitude towards the whole situation.
I've spent time learning Farsi and Arabic. There are so many languages in India that it would be hard to pick one that 'everybody' would speak. Hindi is probably the most widely spoken language in India, but it's still localized to other parts, the farther north you go the more it changes. They speak Urdu in the northwest.
Anyway, I don't think learning languages is the key. It won't help your job security, it will just help you communicate with your co-workers. Software engineers have all of the problems that have been previously mentioned. The best thing to do would be to get a degree in Electrical and Computer Engineering. Suddenly you have huge new avenues to explore outside of software. I love software at heart, but having the ability to design circuits and work on hardware is very helpful in the current market, even if you never do it... people seem to think it is better.
Some companies don't follow all the trendy new languages and such. A lot of federal agencies stick to tried and true programming languages and APIs because they understand that it works. The armed services (and I think maybe NASA too?) writes a large portion of their code in Ada, and I don't think they're planning on changing any time soon.
It's really about where you work and what they do there. Internet stuff, you're bound to have problems. Applications, you may have more life in you. And knowing your hardware and software can be a great asset to boot.
I think we should be much more worried about the trend in using flash for everything. I've seen sites that have whole link bars, with no special effects that warrant it, done in flash. Isn't that' what an href is for?
I do a lot of web developing and I've come realize that a lot of things that I want to do cannot be done without having Javascript in the link. While it is sometimes annoying when I'm browsing a site and cannot directly link to a page because they use a POSTed form inside of a Javascript, there are many many positive uses for Javascript, such as history.go(-1).
She comes from a tradition that I think emphasizes physical things. She completely 100% expects for me to buy her a multi-thousand dollar engagement ring, to be shortly followed by a multi-thousand dollar wedding ring.
I told her that this was just simply not an option. I do love her, but even with all moral arguments aside, $10000+ for two little things to wear on your fingers? I posited to her that it would be so much more useful to put the money into something else, like a home or a bank somewhere. This seemed to have no effect on her.
She simply responded with, "but I want to have rings to wear..." I really do love her, but my god I can't understand how she can be that in love with a completely fictitiously inflated diamond ring.
I'm planning to get her an extremely nice ring in platinum, and it will most likely unfortunately have a nice diamond on it or I really do believe she will never, ever forgive me.
It's just the reality with some women, it's her culture (she's Iranian, they seem to have this thing for public display of wealth, and a diamond seems to count).

I have BellSouth and my local exchange uses "200" to read back the ANI number.
How does Cingular have separate GSM and TDMA networks? The GSM standard uses TDMA, not CDMA or AMPS or any of that other stuff.

I mean, logistically, how do they cope with it?
