Cool, that makes sense... I guess you're saying that a single parameter (the diameter) is sufficient to describe any circle, and that you only need two parameters if you're going to describe the circle's position in >1-space.
A figure 8 curve is an example of a 1-dimensional space that is not a manifold... Secondly, circles are 1-D, not 2-D.
Could you clarify those points? I don't see how either a circle or a curve can be parameterized with a single variable in either an oriented or a non-oriented space, which is (or at least should be) the criterion for single-dimensionality.
Whom would you prefer to own this particular bit of nasty IP? Microsoft (who has never initiated a patent-enforcement action to my knowledge)... or Sony?
Search engines weren't exactly a solved problem when Yahoo/Altavista ruled the roost. They're not a solved problem now, but pretty much all of the low-hanging fruit has been picked... by Google.
Beating Yahoo/Altavista didn't require any truly revolutionary leaps. Beating Google will.
The average person buys a retail Maxtor at CompUSA
Actually, I still haven't found a cheaper source of drives than those red boxes at CompUSA, at least not on the Seattle eastside. The local "enthusiast" shops like Hard Drives Northwest are only too glad to sell you the exact same drive in a plain anti-static bag for $15-$30 more.
I have seen zero failures out of maybe a dozen Maxtors from CompUSA over the past 4 years. Not a bad way to go IMHO.
I think the original poster was pointing out the "capitalistic" barriers raised by the owners of the hard-to-access journal content. The only reason the specialized journals can't be indexed efficiently is because of the burdensome intellectual property policies they currently rely on to make money.
What we need to do is be patient a few more years, and the same running-dog capitalistic system (you know, the same evil system that brought us Google) will finish off those inaccessible, elitist journals nicely.
Many people don't get this. It doesn't matter if it was better or not.
We'll never know, will we? They won, after all.
Microsoft effectively took the "better" gauge out of it when they chose which browser their consumers would use
Shyeah. Just like General Motors effectively takes the "better" gauge out of the car-stereo market when they choose what radio their consumers will get free with the car.
By your reasoning, Alpine, Kenwood, and Blaupunkt should be dead at the hand of Delco.

That, and the fact that they built a better Web browser.
What's to stop someone from signing up with one account and distributing the authentication information to all their friends?
Um, the fact that they have to pay for all the pages their friends will leech?
Why should Slashdot care if someone creates a 'cypherpunks' account? What difference does it make if the 1000 page allowance is used by one person or 1000? Unlike the NYT and other free sites, such an account is useless unless it's paid for.
...and much of the information on the Internet is either dead wrong, or carries an agenda that isn't discernable to your average student.
Funny thing is, that's true of most books, too.
Teaching kids that 90% of everything they see, hear, and read is at least subtly wrong seems like a good idea to me. If the Net can encourage critical thinking skills by driving that point home at an early age, so much the better.
This guy's spectrum analyzer output looks too perfect, which makes me think that it's not very sensitive at all.
Also, that "clean" look is just video filtering in action. Perfectly normal. It looks fine to me, except that I would probably have taken the shot at 100 kHz RBW instead of 1 MHz or 3 MHz like he did.
Yep, the old Tektronix 7000 scopes had quite a few spectrum analyzer plugins (7L5, 7L12, 7L14, 7L18). There were probably a lot of other manufacturers doing the same thing -- it was a good idea.
Besides using too wide a resolution bandwidth to distinguish the apparently-unwanted sidebands from the information-carrying ones, he might have gotten some blurring due to excess CRT intensity cranked up way high (to make the photos look OK, maybe).
He still gets major points for actually measuring the WLAN hack instead of the usual hand-waving I-got-50-HP-from-my-new-coffee-can-exhaust approach. I think his conclusion is basically valid: the sidebands are undesirable IMD-like artifacts, growing at a faster rate than the main lobe's power is increased, but they're not likely to be strong enough to be a real nuisance to anyone.
I saw some cheap used oscilloscopes in a local electronics surplus store at the weekend. If I got my hands on one, how would I go about measuring the frequencies like those guys did with their Linksys? Does one have to buy an antenna, or can it be made? Do all oscilloscopes have the necessary inputs for this. Are there any other considerations? Is this directional (depending on antenna, I guess)?
The instrument used to make those screen shots is a spectrum analyzer, not an oscilloscope. Both instruments display amplitude on a vertical scale, but an oscilloscope displays amplitude versus time while a spectrum analyzer displays amplitude versus frequency. They are very different tools, and any serious RF hacker will own both.
In general, an analyzer is much more sensitive (they normally display RF signal power on a log10 scale, so their dynamic range in voltage terms can exceed 100,000,000:1.) If you had a fast-enough/fancy-enough oscilloscope, you could run an FFT on its display and get the same basic information, but the SA is still the tool of choice for most RF work above 500 MHz. The insanely-fast scopes that can do microwave FFT analysis come with Ferrari-size price tags (literally), and they still don't have the dynamic range of a $3,000 spectrum analyzer. Different horses for different courses.
Sorry for the rather basic questions, but I'm not an EE, and I've only used an oscilloscope very briefly about 12 years ago. I really want to find out where the interference for my 2.4GHz phone is coming from, and how moving the base station helps. I also want to put an FM transmitter on my sound card, and so I want to see how that works too.
For both of those purposes, a spectrum analyzer would be the right way to go. An analyzer capable of 2.4 GHz coverage can be had for under $2K on eBay, but not much less. Some 802.11 hardware can give you reasonably-decent pictures of the 2.4 GHz spectrum, so I'd investigate that possibility first.:)

Germany's a nation, not a "race." Your(?) mention of human rights in the context of German law and culture was what started this (sub)thread.

Um, no. But thanks for playing.
There are no good or bad guys. There are communities of individuals of the species homo sapiens, the majority of these community drew up a plan of how they want to coexist. They can choose whatever "rights" they want.
Correct, until a bigger, badder community of individuals arrives and dictates otherwise. Aren't you glad the biggest, baddest community around at the moment (the USA) has a more liberal perspective on freedoms of speech, press, assembly, and religion than you do?:-)
