I don't know the future now. If I traveled to the past, would I know the future then? If not, how would I know where I came from? Would I end up thinking I was always there? Who can say there aren't many unaware travelers among us?
But the marbles are all touching so they move together at the same time. Or, substitute a stiff, long iron bar for the marbles. That is, the bar is 1 inch high, 1 inch thick, and about 2500 miles long. You push on the end of the bar in NY. When does the end in CA move?
Yes, this reminds me of something I can't figure out. It's a string of marbles thing. Imagine a string of marbles stretching from NY to CA all touching one another. Push on the first marble in NY. How long before the last marble in CA moves?
Does it move immediately, or does a pressure wave or something have to propagate along the string? Seems that if it moved immediately, a signal would be traveling faster than the speed of light.
It's restricted because there is a tremendous amount of compelling evidence that smokers are far more likely to die than non-smokers.
So you don't smoke and you won't die? I suppose you meant to say die early. But your misstatement reveals a crusading attitude. Whatever way you die, it's likely to cost a lot of money.
No, the main reason tobacco is restricted is because it's an easy target for a sin tax.
And yes, I wish I never started smoking but does that give you the right to make a bad situation worse by taxing me for something I'm physically addicted to?
And quitting isn't just a matter of willpower. I've tried many times. I suspect that those who can quit have a body chemistry that reacts less strongly to nicotine.
So aim your laser at the planet Jupiter and modulate it with your data. Detect the laser light when it bounces back and there's your stuff again. Catch it and send it on its way once more.
Ok, you may have to wait a while to get to a particular section of the serial stream, but you could repeat important things at know intervals and be guaranteed to find it within a certain amount of time.
Not enough space to hold your data? Point your laser at Pluto. Need more space? How about one of those recently found planets around a distant star?
Produce redundant streams if the data is important. If you miss one stream, catch another.
I, too, just read Command Line for the first time and enjoyed it very much. Thanks. I haven't run Linux in a few years, but my interest is now rekindled.
A system that operates "closed loop" is more robot-like than one that operates "open loop". A closed loop system compares a measurement to a setpoint and adjusts a system variable to minimize the difference between the measurement and the setpoint. I've spent time developing and testing PID process controllers and it's fascinating to watch them operate. They seem eerily human.
Oh yeah, I remember that. There's something similar called Arachne. It's a graphical dos browser that still seems to be under active development. Long live dos. Why do things the easy way? Here's a link to Arachne:
I use an old 166 MHz Compaq Armada 7730 as an ebook reader. The 12 inch display is much better than a pda. I'm running 98 on it and can view pdf and chm files just fine. An even older machine would be good enough for text files like those from Project Gutenberg.
But we already have taxes on wealth. Aren't real estate taxes based on the value of a home? And isn't the cost of wealth protection (military defense) an ongoing cost?
I don't want to see more taxes. I'm again' em too. But I'd like to see more fairness. Simplify, yes, but in a fair way.
Flat taxes, of course, are not "rigged against the poor" at all. All citizens pay precisely the same fraction of their income in taxes. The only way you can come to the conclusion that they're rigged is if you start with the assumption that the wealthy should pay a bigger percentage, which is circular reasoning at its finest.
An additional dollar to someone making $25K is worth more in improving his living conditions than that same additional dollar to someone making $250K.
In addition, since a large part of taxes go to the military who protect the wealth of those that have, shouldn't the wealthy pay a higher percentage for that?
This article gives a two-factor security example in which a bank mails a user a sheet with perhaps 50 scratch-off numbers unique to that user on it. The user would need to enter a password and one of the scratch-off numbers to log into his account. Once a scratch-off number was used, it would "die" never to become valid again. A new set of 50 numbers would be mailed out each month with the bank statement.
The banks where I do business don't use this, but it seems like a really good idea. IANASE (I am not a security expert) but isn't this a one-time pad approach? Has anyone seen this used? It may be more common than I realize.
Could the idea be expanded to other fields? Is there a better way than snail mail to deliver the scratch-off sheets?
I eat this twice a week. It's good enough.
Instant Lasagne:
1 can Beefaroni
3 spoonfulls Ricotta cheese

mix together
no need to heat
Use Chef Boy-ar-dee if you're having company.
A grasp of mathematics is no doubt essential in order to become a competent programmer. As well, methinks, an ideal programmer would also be a circuit slob. Just as important, I'd say.
Pull the four aces out of a deck of cards. Don't look at them. Give any 3 of them to a friend and keep one. Send the friend on a 2000 mile plane trip. Nobody knows which 3 cards the friend has. They could be any of the aces. After the friend reaches his destination, look at your card. It's the ace of spades, for example. You instantly know that the friend's 3 cards are the aces of diamonds, hearts, and clubs.
I don't get it. I like to read about cosmology but the way things are often explained confuses me. Maybe someone can help.
So we see back to 0.3 billion years after the big bang. What was that, 12.7 billion years ago or so? And the light that comes to us from that place took 12.7 billion years to get here. But how long did it take for whatever is producing that light to get 12.7 billion light years from here? If everything was in one place to begin with, it must have taken time for pieces of it to get somewhere else. How much time? Maybe 12.7 billion years at the speed of light. Wouldn't the universe then be at least twice as old as 12.7 billion years?
Do these questions make sense?
No! No! No! Don't dumb down my devices!

So some people can't figure out how to use the things they buy. Too bad. I say add more features. Many features require little in the way of additional hardware. Why not include them even if they're not used often? Granted, sometimes there are bad interfaces but a bad interface is better than NO interface!
It's sad. Look at what happened to digital watches. They're much more reliable than analog watches and they died only because people couldn't figure out how to set them to the correct time.
On a similar note, I'm beginning to hate PowerPoint. Why does everything have to be broken into bite size pieces? Give me high density information. I'm a big boy. I can read a white paper.

Evolution would stall without misteakes, would it not?

By my definition, though, a toilet is a robot.

Ever heard of marginal utility?

How about a progressive tax on wealth?

So how is this different than EPR pardox?:

How about human power?
Hook up a generator to a stationary bike.
Some rough calculations:
max instantneous human output = 0.1 horsepower = 75 Watts .026 horsepower
20 Watts needed to power laptop =
seems possible without too much exertion
energy calculations:
1 Watt hour per 0.85 calorie
1 slice pizza = 200 calories
therefore, 235 Watt hours per pizza slice
at 100% efficiency, 11.75 laptop operating hours per pizza slice
at practical efficiency (30%?), 3.5 laptop operating hours per pizza slice
Does this seem reasonable?
