turns at 15 revolutions per second, sweeping out a solid white sphere.
I definitly don't want it until they get up 85 revolutions per second, and probably more. And I thought that 60 was horrible, imagine what 15 Hz would look like.
You are absolutly correct. Instead of impedance, we should care about efficency as far as the headphones relate to battery life.
Most people want a specific volume coming out of the headphones, and don't care what the input power is as long as the output is correct. Since more efficent headphones will use less power to make the same volume, they will make the batteries last longer.
In fact, I think you could neglect impediance as long as the amplifier is reasonably efficent across the range of voltages it can produce.
I just got sidetracked into impediance because that is what people had mentioned, but really efficency is more important.
V=I*R, if you decrease R by 1/4, then the volume or output voltage of the ipod needs to be raised by a factor of 4. If you stay below this amount, then yes, the higher impedance speakers will result in a longer battery life.
You can't neglect volume setting, because that is where the voltage comes from. If you have a volume of 0, then your voltage is 0, and headphones don't matter.
If you have 8 Ohm speakers at 75% you are drawing X Amps. If you replace those speakers with 32 Ohm speakers, at the same 75% volume, you are drawing.25*X Amps, or 1/4 the power..75 * X times the length of time would be the number of Amp-Hours that you saved by using the speakers with the higher resistance.
So, the headphone type is VERY important for determining the battery life, unless no power is sent through the headphones.
Practice makes perfect. But, does a lack of practice make horrible? Quite possibly, through atrophy, or even never having done something.
During high school, I had such a great memory for what the teacher said that I could just listen, without taking notes, and then without studying anything, get good grades on the test. Throughout college, the classes where I struggled extremely were the ones in which I was expected to learn certain things outside of class. In those classes, since I had no practice of studying, or even the belief that I even should study, I did relatively poorly.
The people who are smart enough to go through High School without even having to pay attention are in a worse situation than I was, because in college, what the teacher says is very important.
+++ is the modem comand to break out of the data mode and go into command mode ATHO means "hang up" so, "+++ATH0" being sent from the computer means hang this modem up now!
to embed that into a ping, use the "ping -f data" command, with data being +++ATH0 in aschii/hex
Um, yeah, and that would get mismanaged into oblivion.
And, why on earth should the government be responsible for creating software? I do not see free software being used for the defense of a country or for public safety.
Why don't you start a company that charges a yearly flat fee, and gives access to the software that your company produces?
One of my teachers at school had to use powerpoint slides from another teacher, and the one presenting them to my converted the slides to.pdf *JUST* to get rid of the animation, because he would flip back and forth constantly, and the animation would take most of the class otherwise.
"The theft of copyrighted material is far from a victimless crime," said Assistant Director Reigel of the FBI. "When thieves steal this data, they are taking jobs away from hard workers in industry, which adversely impacts the U.S. economy."
Even the assistant director of the FBI doesn't know the difference between theft and copyright infringement.
He's not complaining about latency, but the delay from the low-power state until the mouse realized it has moved.
On the cordless mouse I have here, you can see the difference, as the light goes from bright to dim, and then finally to blinking, with the blinking getting slower. If you move the mouse when it is blinking, it takes a while for the mouse to detect any movement, relative to how long that takes when the mouse is running at full power.
Yes, but what the kids were testing was the way that the IT department/person had set up the server, which is kind of hard to replicate without having much access to the school's server.
Your comment would be true if there was a flaw in the software itself that the school was using, like if they used IIS for a webserver that also had a database with the SSNs in it, and that version of IIS was vulerable.
No, I would say that this is a very approiate use of flash. We are looking for a video, so we expect some sort of plug in. However, not having normal video controls is quite annoying, but it is an approiate use of Flash.
The menus aren't made with flash, which is where Flash gets annoying.
Yeah, I have this display on my '98 Jeep Cherokee, and it is kind of distressing, with getting 4 to 9 mpg accelerating, and then 20-30 braking to a stop light.
However, I just don't care about how much gas I use (obviously- it is a Jeep), but it is cool to see 65-75 mpg going downhill from my house for 5 miles.
Heh,my primary interface to my computer is still a terminal, but inside a GUI. The only applications I use that really use the mouse are Mozilla and Gaim. For the rest, I use the keyboard primarily, for school work (Emacs, gcc, and latex) and such.
The problem with a FM transmitter for the iPod is that you sacrifice quality. A better solution is to get a new car radio that has a 1/8" line in on the front, then you just connect an audio cable between the iPod and the radio, and you power it with a cigarette lighter. This means that you would have to get a new radio, and an iPod, but once you get a radio that has a line in, you don't have to change it if you get a new portable, because 1/8" is essential in a portable music player.
If this is a LCD projector, that would be pretty cool, because I can't go to a normal theater. 72 hz in a dark room isn't quite enough, so if they want my dollar, they will need to make it faster.
you forgot moving stuff from documents and settings to a backup drive, and saving settings that programs have in the repository.
that would work in linux too, but you can have/home be a seperate partition, and install red hat and be up and running with all of your data after just copying stuff off the red hat disc.

watching TV (just games/movies on ps2 and dvd) is tolerable if I have plenty of ambient light in the room as well.
I can't go to a movie theater, though.

And, think expensive, as you have to replace all of the hardware too.

You forgot Rule number three:
sue everybody, regardless of how small the connection between them and the case is.

You mean, you hope that you need more than a social security number to do anything in someone's name.
I want my SSN to be just an identifying number and not a password to my credit too, but I am not too sure that it is going to change quickly.
heh, they might name the next gameboy the gameboy junior........

I think a more deserving mod for that post by mfh would be "ironic", as he obviously doesn't care whether /. will allow large uids.

Aside from that, you are correct, though.
hmm, if there aren't any break; statments in there, that is actually quite interesting.
but, any section of a program that would use that without any breaks in there would probably be just about impossible to understand anyways.
