I just tried the examples. I think many people would fail these. I didn't because I was carfull and took my time. But if this was on a real web site I'd have the REALLY want to to access it. Mostly I'd say "to hell with this" and find some other web site. It tkes a full minute to work through it, way to long for most of us.
Why not have the user read a short story then answer a multiple choise test. like "What do you think mary will do next? (a) develope a dislike ofdogs, (b) kiss john, (c) jump off a bridge. ---- That would work well. it asks to much of your users time.
And I mean it literally -- why have any physical storage at all? Why not just bounce chunks of data around forever on the Internet?
Good idea but some one first tried this in the 1950's The idea was to send the data encoded on a microwave beam and aim the beam at the moon. The signal would bounce off the moon and come back to Earth a few seconds later. A receiver would detect the signal and feed it back to the transmitter. Many thousands od bis would be stored in the radio signal.
This was an extention of then current technology which was basicall a TV set with a tv camera focused on the screen seding it's signal back. The data was stored in the CRT's phospher. The storage devive actualy had the TV screen and TV camera inside the same vacuum tume as an integrated device. Bit were stored as dots on the screen
The then someone (at MIT, I think) invented the magnetic core and sold it to IBM. The core moad all of these "regenerative" systems obsolite. Core was the way to store data untill recently when semiconductors took over. In fact many of us sometime slip up and call RAM "core". Memory dumps are still called "core files".
So untill the early 50's all data was stored as you suggest - it was sent some place and then echoed back an resent endlessly.
I agree for the most part. Concenting adults should be able to make and view whatever videos they like so long as the making of such video does not cause harm to a third party. For example maybe I'd like to make a video of YOU being tossed into an active volcano? Maybe some one would like to watch it. Of course you would not consent so we don't ask.
It is kind of the same with minors when you make kiddie porn. No one askes them and even if they did a four year old can't give informed concent.
Wow this is a slow news day. I remember watching the duct tape thing live on TV back when it happened. This is not newly released information.
The question everyone asked was "how coud you tear off a fender by brushing against it with a hammer?" the answer was the it and everything sent to the moon was very thin and only just strong enough to do it's job. The fender was only designed to deflect dust, not hammer handles. same with the skin of the lunar lander, Not much thicker then aluminum foil. As I remember the LM operated at a very reduced pressure of about 1/5 of an atmosphere so the skin could be very thin as not much pressure was inside. Same with the space suits and every nut bolt and screw -- all as light as possible.
It reminds me of a sign that the guy in charge at Lotus, the sports car company had. His name was Chapman and the sign is reported to read "If it is not just about ready to break, it is to heavy."
The trouble is they can't validate EVERY unit they buy. They test out one model number and firmware revision and then expect every unit like that to be identical. With Fakes the assumption is no longer valid.
Have you ever bought a fake Rolex. I have. First off all parties tho the transaction know it is a fake. So after some efort I find a shop that has a suply of fakes and find that I get to pick between some horrible very poor quality fakes and some decent fakes but none are even close to "real". The poblem is that is costs a lot of money to ake a real rolex. I bought the fake more as a joke to show off back home "look what you can get in a poorer area of rural Korea for $15."
Cisco fakes are completely different. These fakes really are identical even to experts. And I'm sure only one party to the transaction knows they are fake.
I think your #1 would be very rare. The time and energry required to get to Earth are greater then the resources they could gain.
Another argument is that only civilaztions that are a log like each other bother to fight. If they are very much different they would not both want the same resourses and there would be nothing to fight over. Likely any over cililization is many thousands of year ahead of us. Certainly anyone who can come here is that far ahead of us.
I suspect the in the future, even the close in future of the next couple centuries the only thing of value will be information. Specifically art and science. Good art and science will always be the product of a very few humans while everything else can be can automated and produced dirt cheap.
An invader would not want to destroy earth if the only thing they valued was art and science
"I mean seriously -- if we think our technology and culture is okay for the entire planet, why should we stop here?"
You have this completely backwards.
In every case we've seen when technologically advanced group meets a a less advanced group. It is the less advanced group that "disapears". Seeing at our civilazation is only a few thousand years old chances are that any other one we contact will be much, much older. It is us here on Earth that would go the way of the American Indians.
But is that really such a bad thing? The Indeans were a neolithic subsistance culture. Most did not live to become adults.
The fuel used had a very high flash point. You could get a bucket of the fuel and drop a lighted cigaret and it would just go out. Basically it was a low grade of fuel oil that was pretty hard to ignite. The feul was developed just for this aircraft so that it would be safe. It had a dye in it, purple,I think sothat you could know the right fuel was used or if the stuff on the floor was not purple to "do something" about it.
You "only" have to move the asteriod a few thousand miles to make it hit the Earth the next time around. Next time around is on the order of ten years. That's (say) a 100 foot per year velocity or about 4 inches per day.
The abouve is very crude numbers but you get the idea: You don't have to push it so hard, nothing even close to the.22 cal bulet hitting the truck
Next, maybe you don't know it but the satilites weight many tones and are about the size of a trailer that a semi might pull. And they are moving maybe 20 times faster then the.22 cal bullet. Could hitting one of these change the asteriod's speed by a few inches per day?
You have to stop thinking about school as only being a rount to a job. What's importent is not the nuts and bolts of how to write programs. What's always more importent is the bigger picture. Even if you take the materialist "I want money" point of view you have to notie that the bigger the picture you get to think about the more money they pay you.
In 20 years no one will be using today's programmig languages. OK maybe C will servive but java, ruby and Perl will go the way of what was in style when I was in school (PL/1, cobol, fortran) Don't go to a place that teaches the technology of the day. Theory never changes. Math never changes.
Also there is a huge advantage to going to a small school. I went to both UCLA and Loyola Merrymount U. (both in LA) You can get a better education at a place where at facilty and staff know you by first name. When I greaduated I was the only CS major that year at LMU and only the second one ever from that school
I think the big technical school is best for graduate level work.
Talk about global warming! Could you imagine how hot the Earth would be if we collected all the energy from a Dyson Shpere and sent it to earth. The Earth would actually be hotter then the sun. Heck with the Earth the whole inside of the Sphere would bake.
Even with a small scale system you are in effect adding surface are to the Earth and causing it to collect more solar energy.
It will be a LONG time before we run out of surface area on Earth and need to put collector panels in space. Would be cheaper to lfoat the pannels on barges in the ocean then to put them in space. Even if the floating pannels need to be 10X larger.
You are correct "once a big enough hole was made" but maybe with the use of stronger materials the hole would have been smaller. Smaller enough to prevent sinking or delay it until help arrived we will never know.
The glossy screens are intended for the averageuser who is a "media comcummer". This is someone who uses his computer mostly as a media player either for DVD movies, games or internet. I think 90% of all computers are used this way now and for that the bright "out of whack" colors are what they want. If you are creating digital content you want "accurate" color and an anti-glare screen.
Apple's Macbook Pro comes with thescreen you want. Even if they do cost a bit more than something else, it is worth paying an extra $1K just so you don'r have to use MS Windows.
What's the difference between unsoliticed snail-mail marketing and unsolicited email
Easy. With snail main the sender pays for it with a stamp. With spam the sender uses other people's resource to send the mail.
Actually look at spam from your point of view as an end user spam is a bit like jumk mail. All yuo have to do is sort out the crap and toss it out. but from the ISP's point of view spam is very costly. What if the junk-mailers used fake stamps? the post office would be very upset but you would not care much. This is what's going on with spam. the spammers are costing the ISP's a a lot of time and money
spam is more like telephone marketing than junk mailing.
That law that states that unsolisited material mailed to you is "yours". Is very, very importent. If it was not there I could mail anything to your house and then demand payment or that you pay postage to return the item.
I tried a little test. My kids are not what you'd call computer experts. Just typical kids ages 9 and 16. They use both Mac OS and Windows. I put a Linux Ubuntu system up and made them a logon account. Having never seen Ubuntu before they are able to do all the normal taks they did on the macs. There was not learning curve or comming up to speed. That said, the biggest problem with Linux and other UNIX systems it that you can't run the Adobe or Apple suit of applications. I LIKE Apple's "final Cut Expres" and Aperture and the Adobe creative Suite so I have some Macs at home. Here in the office it si 100% Linux and Solaris. But in terms of ease of use at the desktop level they are all the same.
A good way to handle asbestos, if you have to clean it up some place is to spay water on it. This keeps the dust down. Th danger is if you breathe the dusts. asbestos by itself is a natural substance and not harmfull untill it is disturbed and gets into the air.
Yes Beta 2 exppired today but Beta 3 was also released today. There was a gap of a few hours. This software is for DEVELOPERS and has not effect on end users.
If they track your location they can automtically send tickets to 100% of the drivers you drive to fast or run lights or roll through stop signs. Maybe some day there will be a law requiring every car to be tracked. Think of the millions that city must loos because they can't ticket every speeder.
Apple's multi-touch track pads will let us see if getures are a good way to control computers. If it is then I can see that the nest step will be to do away with the touch pad and just move finger n the air while a web-can type device watches. That could use use a few cores. Watching a user's eyes to see what part of the screen is being read could be usful too. What about sorting my library of photos by object, for example finding all the ones with a give person in them? There are lots of uses for computing power. And then there is alwys voice

Years ago I kept my lines to 72 characters. Now I''l let them go much wider, to maybe 100 characters. they fet better on today's screens.
Either the F-22 has better stealth than we realize, or there's something newer, more stealthier and more secretive coming around.
Yes. un-manned aircraft.

As for PostgreSQL documentation. Just do a search at amazon.com you will find enough there. More than you could ever read.
