When I go to McDonalds, there's no pretense of nutrition or calorie reduction. I order a regular combo with a regular coke
Yeah, because more badness is better than less badness. And you think that people, who apparently cannot resist their urge to eat Big Macs, but somehow manage to at least drink diet coke instead of regular, are funny?
This effect is called "digital cliff". [...] With analog modulation, you would get more noise in information when you get more noise in signal.
This digital/analog comparison mostly holds for AM. In FM, the audio quality also remains good as long as the signal-to-noise ratio is above a certain value, only to plummet below this value. This is known as the threshold effect and it was already known to Shannon in 1948.
The best part is when you assume that "those outside the US" somehow are unaware of what you perceive to be heavy-handed police tactics, when the sad (to you, anyway) truth is that people outside Western nations routinely live under oppression and police abuse
The best part is where you assume the US is the only western nation.
Who is talking about sexual assault? If you give someone consent to take a video of you having sex then you need to beware, you just gave up some of your privacy rights.
It may not be sexual assault, but it certainly isn't a "minor thing" either. I don't think GP should have been modded flamebait. But this is
NO-ONE of these people gave any consent to put these videos on The Net. Is that so difficult to understand?
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...
On a side note: security was a lot more relaxed those days...
I know it may not seem like much, but multiply it by millions of bottles sold and it adds up to a hefty hit on their bottom line.
You are completely correct. In the past Heinz has even been caught cheating by underfilling their ketchup bottles.
There's exactly zero ways "I drive a Virgin" sounds good,
Indeed, "I ride a virgin" sounds way better.
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.
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.
The person who thinks they know it all quite often knows all too little. We are not yet at a point where we (collectively) know it all.
Pssst! Looks quite like the Dunning-Kruger effect.
