Acceleration due to gravity has nothing at all to do with the mass of the falling object, only with the mass of the attractor. Read up on your physics.

With regards to the second nano-machine in the article that was invented by the Dutch and Japanese scientists...
This motor spins on energy gained from light. Would it be more efficient than our current photovoltaic cells to generate electricity somehow with these mini-motors?
Maybe use the motors to bounce around a solution, creating heat energy, and using the heat energy to generate electricity.. Or a more direct method that someone more clever than I could come up with.
If I were a dictator who controlled the cure for HIV, I could innoculate all my countrymen, then do everything in my power to hasten the spread of the disease everywhere else, secure in the knowledge that my own people were safe.
Just about anything can be twisted for a negative purpose.
(1) I have a high-speed internet connection at home by way of ADSL.. It would definately be nice if TiVo could make use of that to download the programming information instead of tying up my phone line.
(2) More importantly to me: Removable media! I would be a very happy camper if I could archive recorded TiVo shows. I don't know what the insides of the box are like, but I wonder if it would be possible to add a DAT drive to the system.
I just cannot justify spending that kind of money for delayed viewing without the archiving capability, too. I'd be willing to buy a TiVo and an external DAT drive, though, if this was possible.
Mr. Bullwinkle, would the layout of the box allow for something like this?

Yes. This is an interesting story, but it's still a long way from 'dust'. These things are currently 5mm big, which they hope to halve.. Half is still 2.5mm. About the size of a tick, for instance. Something you'd notice stuck to your skin, and definately way too large for inhalation. They could have some novel uses, but it's still a far far cry from nanotech.
This exact same device was posted on slashdot on 6/31/99 (by CmdrTaco himself), and 6/6/99 (by Justin)...
The 6/31/99 reposting didn't bother me because it was a listing of a number of miniaturized computing devices, but this repost adds no new info whatsoever.
in your/etc/isapnp.conf file, you'll have to specify io base and irq for your cards. then in your/etc/conf.modules, append io=whatever irq=whatever. PnP cards [are supposed to] have a unique identifier serial number, so if you put one card in first and do a pnpdump, you can read the output and find out what its serial number is. then you'll know which card is which once you put them both in.
Yeah, no kidding. It makes me wonder: how hard would it be to build a circuit that converted from SVGA 15-pin input to LCD? Fit the circuitry into a base to hold the screen up. Buy a laptop, take the screen off of it, attach connector/base. Voila, budget desktop LCD, with a whole self-contained computer left over. (car mp3/gps/whatever?:))
Uh... What sort of "secret" information would you possibly be broadcasting across the entire campus? And if you're broadcasting it over the airwaves, it's perfectly legal for someone from another school to listen in.
I went and checked out the WaveLAN pages, and it looks to me like the fastest one they offer is the WaveLAN IEEE Turbo PC Card. The description for this product claims:
The High Speed Option gives
3 times more effective throughput as the Standard Speed option. Standard Speed and Standard Low Speed are the equivalent to the throughput offered by the WaveLAN IEEE radio.
Standard Speed being equivalent to 2Mbps, this indicates to me that this Turbo card maxes out at 6Mbps. This falls short of the 11Mbps promised from the AirPort product.
So I wonder if they are really the same product after all. I'd love it if they were; I'd buy 3 in a heartbeat at $99 a pop. But the lack of any 11 Mbps option on the WaveLAN page makes me wonder.
Yes. I concur; this looks like a scam to me. I mean, heck.. They're attempting to build a massively parallel computer, yet they consistently misspell the word "parallel" itself? Once or twice I could pass off as typo... But they never spell it correctly. Smacks of ignorance of the subject matter to me. Even if they're not scamming, I suspect they haven't really thought this all through.
Your comment inspired me to go and do a little bit of web-browsing... http://www.advancedvisi on.net lists a few DVD drives in the $70 (USD) and under range. Definately getting cheaper.:)
that's what i do, too. i wish that books.com would bring back their user commentary section; that's the only reason that i go to amazon.com. books.com is guaranteed to have cheaper pricing. they will go check amazon's price real-time and undercut them! how great!:)
What if someone were to design a 'neural net'-based search engine? Initially it could be much like any other 'dumb' search engine. Instead of linking directly to the target sites, have the links go back to a redirector on the search engine's server, enabling the search engine to get feedback on what pages the user actually utilizes, out of the multitude returned. For instance, when I do a search on "ADSL and linux", it would learn that I only clicked on the links that actually had relevant material, and ignored the multitude of XXX/porn sites that put large blocks of common keywords on their pages... Over time and use, the engine could learn what sort of information is really relevant to "ADSL and linux", and what sort is really not, and rank them accordingly.
Well, perhaps the computing power for something like this isn't available yet. But it'd be nice...
how about this: outfit each "marble" with a directional antenna, and have them each triangulate their positions relative to each other and to the base set. if you put two antennas in the base set, spatially separated, that'd give you sufficient data to calculate the positions of all the marbles.

When I would point my previous cell-phone at my laptop computer, it would make my mouse pointer move. :)
And I'd done nothing odd to the laptop's shielding..

There are drivers.

I have stability problems with 'em, but maybe you'll fare better.

I have some cards that work under windows. They're Proxim Rangelan2, and they do peer-to-peer. 2Mbps max.
There is unofficial linux driver support for the card, but it's not too reliable in my experience.

Ah, but it does matter; on a lot (most) systems, a user's ftp password is the same password that the user uses for interactive logins.
