Comment: Old news (Score 1) 32

Hate to rain on this guy's parade, but conductive ink pens have already been for sale for quite some time. If he wants to reinvent the wheel, enjoy. Quite honestly, this looks amateuristic, so gefundenes Fressen for artists and "installations", I guess. Sorry for being so negative, it just feels unfair sometimes that hardware designers working their ass of to get you all these nice fancy iGadgets are rarely held in high esteem, while "artists" can "invent" something old, build something trivial (20 lights in parallel!) and makea big deal out of it.

The conductive ink plotter which was featured here some time ago is something completely different, of course.

That way we can get enough sunlight at night to compensate with ground-based solar panels. That's really simple to do, right? Easy Peasy!

That depends a bit on who is "we"... It may also be the Chinese or the Russians, meaning the US wil never get to see the moon ever again.

Anyway, while I assume your plan is not a serious suggestion, allow me to analyze it. For starters: the current non-geostationnary moon already does this to some extent, the spot is just changing all the time. More importantly, the reflectivity (or albedo) of the moon is 12%. This means that, at best, moonlight could be 8 times brighter than it is now. Currently the moon is about 250000 times dimmer than the sun, so in the best case your enhanced moon would still be 30000x dimmer than the sun...

Comment: Re:Article is wrong. Transceivers do this already. (Score 2) 47

The article is misleading. Transmission and reception on the same "frequency" is done today. However, there's some other "discriminator" in the signal. Either modulation method, phase, shift, orientation, or "something" is different so that the receive and transmit don't collide.

Actually, bidirectional, simultaneous transmissions using exactly the same polarisation, modulation etc have been possible for a long time, using circulators/hybrids and echo cancelers. I imagine they had limited succes because typically the power difference between transmitted and received signal is too high for the echo canceler to deal with, but in theory, this "holy grail" is certainly possible.

Apart from that, as you mention correctly, the novelty here is the size.

Comment: bizarre definition (Score 2) 47

By definition its not full duplex if its using a shared channel to transmit and receive.

If you define full duplex in your own bizarre way, then, yes this is not full duplex. The more common definition, however, is that transmitting and receiving can be done simultaneously. And that is exactly what is going on here. Obviously using a shared channel, otherwise it would not be news. And even that is nothing new. Echo canceling and circulators have been existing for ages. The novelty here is the size of integration.

You are not the only man on /. who respects women, but that is not the issue. It is possible to 1) respect woman and 2) not want to have childern 3) welcome new birth control methods.

Typically my ex GFs and I used a condom until we trusted each other enough to go for another contraceptive, which typically was The Pill. If she would have objected to this, for whatever reason, I would have been happy to keep using condoms. No sweat. Respect. Responsability, no problem. On the other hand, "forgetting" to take a pill, getting pregnant, not letting me know on time, not taking any other steps (morning after pill, whatever) wouldn't be very respectful either and would indeed piss me off.

Columbus was probably much smarter than your average lad, otherwise he wouldn't have been able to undertake such a voyage.

He may have been much smarter than your average lad, but at the same time -if you pardon my French- Columbus was an arrogant idiot who went against the common (and correct) knowledge of those days by underestimating the circumference of the Earth by a factor of four. Afterwards he was hailed as the discoverer of America and blabla, but the matter of fact is that he would have drowned if it hadn't been for this random unpredicted piece of land (*) in the middle of the ocean.

(*) Actualy middle-agers made some predictions about undiscovered pieces of land that "should exist" based on some symmetry or whatever religious logic they used. This was not the case for America, though: Columbus really underestimated the voyage and thougt he had arrived in India. The fool!

Well I think that's part of what "respect" means - you don't push your own religious / atheist beliefs in someone else's face when you know they have a different viewpoint.

Publishing cartoons in a magazine one needs to buy in order to see them is not quite "pushing beliefs in someone else's face".

Adding features does not necessarily increase functionality -- it just makes the manuals thicker.
