I always thought that the pure intuitiveness of a search engine such as Google should be the simplest thing in the world. You want to find something, search for "something". Unfortunately I was very wrong and I come across more people every day who can't understand how to locate auto parts or cooking recopies on line to save their lives. The same people who will forward inane emails and play pop cap games all day long.
How is the simple task of knowing what words to use in a search so difficult to grasp? Perhaps critical thinking does come natural... and the rest of the humans have to have other people do the searches.
My dad's had a VW Jetta for a few years now and when I've driven it I've never really run into the nightvision problem. I generally put the lighting in a vehicle on the lowest visible setting, however, because of this very issue. I can't stand losing my night vision. I used to do a LOT of driving on rural roads and without that night vision you can miss a lot of critters. I have also been guilty of falling asleep at the wheel, and never experienced that feeling in his car. I'd done a 14 hour day with six hours of driving with no problems at all, so maybe the blue light works. And I also don't recall having any issues with night vision (again, interior lights at lowest possible setting anyways).
I drive a vehicle with HID headlights now, and they've got that blue tinge to them, I wonder if they're not doing the trick because I've never nodded in this car.
I used to work in construction three years ago. Unless, like the GP poster noted, you're carrying Hazmats, you will eventually start referring to your log book, as your 'comic book'. If there isn't a GPS system in your truck with an electronic log, odds are you're comic book only looks by the book. Most of the guys dropping off our stuff would have a good three days to deliver and return. This was from St. Louis, MO to anytown, MN. He'd be dropping our stuff, and home with the wife and kids within a day. Just for the time off.
Well, after reading through the wiki it self-sharpens when used as ammunition "On impact with a hard target, such as an armoured vehicle, the nose of the rod fractures in such a way that it remains sharp." Its next action is to disintegrate into dust and ignite in a glorious explosion killing all that are near... so... I'm probably going to abandon the idea. It had such potential.
See, NOW you're talking. Heck you could put a tiny, tiny reactor with some sort of altered universe inside the sword to power some sort of mechanical arm for your body. You know, to take out the robots in the eventual uprising and attempted overlordedness they would attempt to attain.
Yeah, I read that article. But if you honestly think that I was replying to an earnest post with anything but jest, you should really find a new sense of humor. Also, having a density of about 19.1g/cm3, it tends to be just over twice as heavy as sword steel (at 7.8g/cm3). Your 2kg sword would be 4.8kg and tire you and your four arms out quite nicely.
True, a uranium sword would be sweet, but what happens when you grow that third and fourth arm? Sure, you'd think the extra gripping power would be 'handy' on your sword now. But what happens when they deliver that bad boy and in your first uranium sword fight they both go critical mass... Did you ever think of THAT?!
The problem with this is that Guitar Hero hasn't even come close to their patent. The patent doesn't seem to be overly broad to me.
Their patent shows that there is a VR headset attached to the player's head (though it does mention a VR 'environment'. I don't think that a TV counts). That would include the video aspect. I haven't read the whole patent, but the experience is quite the opposite of GH. Their patent covers wearing these goggles and playing from a First Person View, as explained in the second paragraph of the patent.
Another problem is that the words "prerecorded video" are thrown around a LOT. All the game play video in GH is generated on the spot.
I think the last problem is that the patent states that you would be playing a particular instrument (as opposed to an input device) so the GH guitar probably won't be covered as it doesn't produce any signals that can be representative of music.
I wasn't thinking about duct taping a bunch of pillows around an iPod, no. I was thinking that if a tape recorder (I haven't seen what they really look like) can be shock proofed in such a manner, that there has to be some sort of solid state material that would survive as well.
As far as expensive goes. I don't know how expensive a 'normal' black box is. And I suppose I expected those to be somewhat expensive already. I searched Google and came up with what looked like a used model for $900. Beyond that is beyond me.
By your logic, you could fit just about any corporation, career path, martial art, committee, political structure, boy scout troops, or literally any group of people where hard work, training, experience and mutual respect can grant higher rank into a 'cult' status.
I'm not a fan of catholicism as a whole, either. And the idea of the Pope isn't appealing either. The Bible really doesn't do a lot of talking about anything 'higher' than elders of a church body. And if you've read Judges and Kings you'd notice that God was pretty opposed to having one ruler over His people. Just real people, being real with Him and His people.
To be perfectly fair, my Nano has done that. Many times. 20', actually. Perhaps it was the exception. More to the point, I think that if you've got enough room in a 25lb box for a magnetic tape drive, there has to be a way to shock proof 1GB of circuitry required to record a whole flight. I'm not an engineer at all. I'm just saying this out of a blind hope that something relatively stationary could be more hardy than a mechanical system. I'd suggest a few ideas, but I'm sure the engineers have thought far past those ideas.
Belief, if you value it at all, must spring from an honest embrace of some purported truth. It cannot spring from a callow desire to avoid consequences.
Don't know what you believe, but being a Christian myself, I've felt the same way for a long time. So Amen.
You typically don't have to lock yourself in for two years. You just have to pay more for the handset, and have the kind that they'll accept. If you buy an unlocked handset you can usually move between carriers okay. And you don't have to sign contracts. Back when I was off contract with Verizon (ages ago) I was on a month to month plan that was the same as my old plan.
So I suppose things haven't changed much. If you have the right hardware, you can move where ever you want, as long as they're willing to deal with you. (activation fees, and all that will likely abound)
Probably because it's half-life is about half that of Pu238. Wouldn't work as long or as reliably for deep space. But that's just a conjecture and I'm no scientist.
First: I completely agree with you that there was enough danger of the tanks surviving to justify active destruction of this satellite.
Second: This last post sounded almost like a craiglist.org advertisement. I'd almost be willing to buy one of these, if I were in the market for a tank that would hold liquid and had a good chance of surviving re-entry. Bravo.
The design goal of Gravia is to provide light in a room (600-800 lumensâ"roughly equal to one 40 watt incandescent lightbulb), over a period of 4 hours, using people to generate power.
Seems to me that the competition website is implying that it can provide the same light as a 40W bulb for 4 hours per lift of the weight. At least that's what the sentence structure implies. A quick search of other articles related to this idea or the student gives no more info.
You could just ask him. The link points to his school website, with which you can look up his email. I could post that, but I don't want the poor guy getting any more spam that he's already most likely dealing with at the moment.... I hope all of that email is telling him that he should be using the metric system...
Also, I've done my own calculations and it looks like the system could produce all of 23mW constant power if that weight were to fall the 1.47m over 4 hours. Some one was saying my work might be off by an order of magnitude, but I'm not sure where.
It doesn't matter what you do with that torque on the end of the system. Either you have a lot of RPM's in your motor with a weak magnetic field and less amps, or reverse all that, but more voltage. (I might have amps and voltage messed up, it's been a while). Either way the same amount of work (Watts) is always being used in total.
Watts = Force x Distance / Time
This never changes. No matter how fast you gear it up at the end. If you get a spindle to turn 160:1 all you're getting is a spindle with 1/160th the torque of the original. Less, actually, because no system can be 100% efficient. It's best to work with what you have. So, use stronger magnets in a brushless system and get more Amps and losing less energy in gearing.
In a situation like this you need to increase the spin just to make a magnetic field. Which is probably why the guy that came up with the scheme figures he needs a 50lb weight. That is the first red flag. He should have been using metric.
Most laptops, too. A good cycling workout converted into energy could easily charge a laptop battery after a few hours. Yes, I consider a few hours on a bike a decent workout. You could step it up a bit for the 90W laptops, too. Won't make too much of a difference, but it will make a difference. Say you need to charge up your cell, iPod (or other MP3 player), portable phone and other gadgets. Throughout the week every evening you'd lose some weight and have some nice looking legs after that.
Except that it doesn't. Do the math. One high output white LED needs 50mW for power.
Force x Distance/Time=W
22.6Kg x 1.47m x (9.8m/s/s)/14400s =.023mW
A brushless motor can operate at up to 90% efficiency, but the friction in the system will reduce the efficience a lot. We'll just say it runs at 60% efficiency. That's just 13.5mW. You need five of these to power an LED under current configuration. They want 600-800 lumens. So we'll lowball the figure with 600. Each LED can do about 80 lumens.
600/80=7.5, so 8 LEDs. That's 400mW of power for the system, or 30 generators.
Either you need 30 generators, a 680Kg weight, a 44.1m tall light (falling 30x's faster), OR a planet with 30x's the gravity. Your call.
Or very tiny handwriting. Back in my college days my classmates would prefer my roommate's messy scrawling to having to get a magnifying glass to read mine. Mine was very neat, but I'd fit 3-4 lines or numbers into a single cell of 5x5 per inch graph paper. What fun.
Slashdot Mirror
They already do. Haven't you ever received a "Pre-Approved" credit card application?
We have it in Minneapolis. I'm not a subscriber but there is presence pretty much anywhere?

Not to start a new bitch-fest about HDDVD vs Blu-ray, but what did you find better about HD-DVD?
I drive a vehicle with HID headlights now, and they've got that blue tinge to them, I wonder if they're not doing the trick because I've never nodded in this car.

Feet vs armpits. Should be a vast difference.

Maybe depleted uranium.

You're just waiting for the inevitable inter-stellar war between the planets of Petrified Natalie Portmans and Hot Grits. Admit it.
