Comment What a stupid question (Score 1) 573

This is just stupid. Why would anyone ask Twitter to do anything of the sort? It's like asking Ford Motor Company "Would you build electric chairs?" Of course they'll say no, just for the PR and to not alienate customers, since they know the government is not going to ask them to build electric chairs.

The fact of the matter is any of several thousand software companies could easily throw together a registry of this kind. It's straightforward stuff. Heck, outsource it to India. They'd have no problem doing it even knowing what it would be used for.

Comment Very interesting, but could cause other problems (Score 2) 63

This is pretty cool. I think in general it's a good idea, however I can see it causing entirely new sets of problems. As drivers we recognize the difference between what we ought to do, and what we must do. For example, there are times when crossing a double yellow line would result in my death, while there are other times I cross the double yellow line safely and without risk to avoid a hazard in my lane or on the shoulder. My concern is people will start seeing these visual aids as things they *must* do. Thus in the process of trying to adhere exactly to the virtual markings, they become oblivious to the actual hazards that are more important. In one of the pictures they show two lane markers projected, which is where the car ideally should travel. On the right there are barriers that are actual hazards that are taking up part of the lane, and to the left is the other lane, which may or may not be an actual hazard. So if I am concentrating on the projected markers (which I assume are "intelligent" because they are dynamic), will it be obvious enough that I am travelling into another lane and that I must make sure the lane is clear of other vehicles first?

The real question though is this... if the car has that much information about the environment to project images that tell you what to do, why isn't the car doing the driving in the first place?

Think about the power to weight ratio--with as little as a plastic vehicle with a passenger or two would weigh on Ceres, the ratio would be very high, especially after they found the ferromagnetics in the belt that could be magnetized a hundred times as strong as today's (that story, "The Pirate", is still in edit), replace the magnets in a 100 watt motor with them, and one watt will run that motor as well as 100 did the old.

They already had real moon buggies, they're still up there. They used wheels, but the moon is a LOT heavier than Ceres.

Imagine playing basketball on Ceres? I might add that to a story, there were microgravity sports in "Mars, Ho!".

I don't back up daily, more like weekly, plus whenever I have a rash of new data. I keep the backup drive unplugged except when backing up, and never in s thunderstorm. Losing my non-backed up data would only hurt a little, it isn't like I'll lose a 10,000 customer database or anything.

Before I retired, backups were automatically done daily by software. I had to change the backup tapes weekly.

Journal Journal: Santa Killed My Dog!

They say that Santa's coming,
He comes 'round every year.
He comes he'll meet a shotgun slug
'cause he ain't welcome here.

Five years ago this Christmas
The fatass came around
With jingle bells and ho ho hos
And looking like a clown.

He came in for a landing
As I let out a yawn
My house is pretty little
So he landed on the lawn.

Those were all bad presidents. My grandmother, born in 1903, said Coolidge caused the depression but Hoover was a terrible president, too. Most historians consider Lincoln's predecessor, James Buchanan, .was history's worse.

I never thought I'd ever see a worse president than Carter, but GW proved me wrong.

You can always kill the phone's sound before bed, and check messages when you get up. You kids just don't understand that answering your phone, whether talk, text, email, amber alert, or presidential alert is NOT MANDATORY. If you're driving, leave the damned thing in your pocket, whoever is attempting contact can wait until you get where you're going.

Stop being a slave to your phone!

If it looks like there may be tornadoes that night, you might want to let the presidential/amber alerts annoy you.

Previewing this, I laughed; this font makes "tornadoes" look like "tomadoes" (I've seen "tomatoes" misspelled like that before).

Do you work for Maxtor or something? I've had hard drives for decades, few have failed and the failures weren't brand specific, and all were old when they died.

Comment Re:Does this account for dark energy? (Score 2) 244

The theory here is that the speed of light was infinite at the start of the Big Bang, not that it is slowing down. The speed of light is not slowing down, and this has already been proven.

So the speed of light was infinite, but now it is not. That is the very definition of "slowing down" is it not? At which point did it slow down I suppose is my question. If this theory can replace the concept of expansion, then it also must explain the acceleration of the expansion, which is what dark energy is theorized to do. So this theory must somehow take into account dark energy as well, which infers that the speed of light must still be changing since expansion is still accelerating.

Another part of this theory doesn't make sense. If the speed of something is infinite, then the size of the universe must also be infinite to accommodate it, otherwise it would "bunch up" as it hits whatever the "every corner of the cosmos" means (which implies there is a finite size to the universe).

However if you spread a finite amount of energy / matter over an infinite distance, the density would approach zero, thus we would not even perceive that it exists. So I guess this theory assumes there is a finite size to the universe that is independent of the amount of distance or expansion that could happen at the speed of light.

Comment Does this account for dark energy? (Score 1) 244

I'm trying to understand how this affects the redshifting of extremely distant objects.

Pretty much any distant stars / galaxies we look at from earth are redshifted, which indicates they are moving away from us. However we know we aren't the center of the universe (where the big bang happened), but that any observer at any other point would see the same affect we see - everything far away is redshifted. This is why we think the universe is expanding - because everything distant is redshifted. Further, the expansion of the universe seems to be increasing, which has resulted in the theory of dark energy to explain why the universe is expanding faster and faster.

However, if the speed of light is slowing, wouldn't it result in the opposite affect (blueshifting)? Photons en route to us from other distant objects (and thus that have been travelling for a very long period of time) are now moving slower than they were at first, according to the theory of this article. If the speed of light is slowing, then that would decrease the wavelength / increase the frequency, which would blueshift, right? Further, the universe isn't just expanding at a static rate, but the expansion is accelerating, hence the theory of dark energy. According to this theory is that explained by the fact that c is still decreasing? If c is decreasing does that mean that the rate of time is also decreasing? Or must that not be the case or otherwise the speed of light would not seem to be changing?
