I think I see what you're saying, the difference is gravity acts on every part of your body so you dont "feel" the force acting on you, even though you are accelerating. The direction of the force vector should be irrelevant, and in the case of the car it will add up with the force of gravity to increase above 1 G. An easier way to think of it may be if you picture yourself holding an accelerometer, which many times is nothing more complicated than a weight hanging from a spring. Sitting on the couch the weight will stretch the spring some, 1 G. Accelerating in the car we have both gravity,(1 G down), and the cars acceleration, (1 G horizontal), acting on it. These forces will sum together to 1.4 G acting 45 degrees down from horizontal. The spring should now be hanging at 45 degrees, stretched more than before. In free fall the spring should not be stretched at all, 0 G.
Wrong, in free fall you are experiencing 0 G. When you are sitting on your couch at home you are experiencing 1 G. Another example; when a plane is flying in a straight, horizontal line the pilot will be experiencing 1 G, if he noses the plane down so that he feels weightless he will be experiencing 0 G, identical to the feeling you get in free fall. You are correct though that the acceleration will be G, 9.8 m/s^2.
In a straight vertical drop you will be accelerating at G (9.8 m/s^2), and the g-force you will feel is zero (yes it may be slightly off due to wind resistance and such but you can assume zero). If this car can accelerate to 60 mph in 3 seconds its average horizontal g-force will be about 1G. So if we are traveling on a flat surface you will have 1G down (gravity), and 1G horizontal. Add the two together and you will end up with a max G of 1.4 at an angle of 45 degrees down from horizontal. In summary, accelerating in this car in a straight line your body will feel a max g of about 1.4, in a freefall vertical drop your body will feel 0G. So the poster was incorrect.
You know everytime the subject of hdd capacity/performance comes up I wonder why no one has produced a hdd with dual servo arms with the capacity to read/write to different sections of the disk simultaneously. More or less single disk raid 0. This would result in an incredible performance increase at a small price increase. Furthermore while raid 0 decreases storage system reliability a single disk with dual arms would actually be slightly more reliable than a standard disk; i.e. one arm fails you've got another one to keep going, (and I realize an arm failing isn't the primary cause of hdd failure). Maybe it would even be possible to optimize one arm for reading and one for writing.
I'm going to take the dissenting view here and say that I honestly wouldn't mind too much if I ran into a few of these a day, if they would help keep some of my favorite sites free and IF they are used responsibly, and thats a big IF. All too often it seems net advertisers are trying to either trick you into viewing ads or makes them so obtrusive that there's no way to avoid them. Lets take a possible scenario here: CNN removes all forms of advertising from it's site and puts a few of these on it instead. Furthermore it clearly delineates links that cause one of these ads to come up from links that don't, either by putting them in a seperate location from other links or by differentiating them somehow (making them a color other than the standard blue for links or going from a solid underline to a dashed underline would be two possible examples). I would be ok with this, its not much different from the way tv works now. In fact it might even be a good idea to force people to take a break once in awhile, have you seen what someone looks like after sitting in front of a screen for 6 hours without blinking? yeesh, if they ran into one of these ads once in awhile maybe they would get up and take a break. I have a sneaking suspicion however that many advertisers would choose to use these ads in CONJUNCTION with established web advertising instead of as a replacement, which would only serve to make pop-up and banner ridden sites even more annoying. It's akin to the current situation with cable television; when cable tv was first introduced the service providers claimed that by having users pay for the service they wouldn't need to use annoying advertisements, which sounded kind of nice. Well obviously that has all gone out the window and now I am bemused to find that all too often I am PAYING cable providers to show me advertisements, which makes absolutely no sense, (unless of course you own a cable company and are watching your bank account grow).
The RIAA routinely hosts bogus mp3's on kazaa. You think you're downloading a new madonna song when what you really get is a loop of her saying "what the fuck are you thinking?". Now I would imagine a lot of these same people that got duped are going to be getting warning's from the RIAA for "hosting copyrighted material" since the file names correspond with copyrighted songs. It's amusing anyway, download a phony from the RIAA and 5 minutes later they're spamming you with warnings for having copyrighted songs on you computer.

Remember a little while back a guy actually got this key using a custom, on-board tap? Whats to stop someone from simply using the same method here.

IANARS (rocket scientist) but what are the possibilities of utilizing the asteroid just discovered that shares the earths orbit for some form of station. A snippet from this article: http://news.bbc.co.uk/2/hi/science/nature/2347663. stm
"Although only about 100 metres across 2002 AA29 may play a role in the manned exploration of space out of all proportion to its size.
Already researchers are speculating that it could be visited by an unmanned spaceprobe or even become the first object after the Moon to be stepped on by astronauts.
The object could tell us a lot about the composition of asteroids.
Some have speculated that it could be nudged into a permanent Earth orbit where it could be studied at greater length."
If you could nudge this thing into the right orbit wouldn't it make a wonderful station? Lots of room, some raw materials, and you could burrow into to escape the radiation. I understand that some asteroids are nothing more than loose collections of rocks and dust. But it's an intriguing, and plausible idea.
Regardless of why people got their cell-phones, part of the reason for almost everyone has to be that they're just plain cool. Now how many of you would want to whip out this crap-looking disposable phone at a party? or when you're on a date?? puh-lease....

Not officially anyway, Athlons run at either 100 or 133 MHz (double pumped) for an effective 200 or 266 MHz. There are some mobo's that let you overclock the FSB to 333 MHz and beyond but the performance increase is only a few percent really.
I'm about to tell you how to dramatically reduce the number of telemarketers calling you. This method is usually done with a device called a TeleZapper but you can achieve the same effect for free.
What's a TeleZapper? Read on....
The TeleZapper is a device that plays the first tone in the three tones that precede the telephone company's historic "This number has been disconnected" message. The telemarketing dialer listens for that tone, and when it is present the dialer assumes the number is disconnected, The result is the telemarketing dialer will immediately disconnect and delete your phone number from it's list. I've seen the TeleZapper for 50 bucks, but you can achieve the same effect for free. How you ask? Simple, just record the "disconnected" tone at the beginning of your answering machine message or voice mail. After a few weeks of letting your answering machine screen your evening and weekend calls you'll achieve the same effect as a $50 TeleZapper. Where do you get the sound file?? Right here at this website:
Ummm if this machine were putting out stamped cd's they would cost a fortune. Stampers aren't cheap to make u know, thats why its only feasible when you're making large quantities of identical cd's
Don't cable providers realize that one of the few "killer-apps" out there for broadband is p2p??? If they take that away half their customers will up and leave. It baffles me how these people can tout the benefits of broadband and then deny their customers the ability to use it.
I didn't say it was unfair, I just said the comparison is sort of pointless. What if I compared my new, 2.53 GHz P4 buttkicker to your 3 year old P3 machine and came to the conclusion that your machine "is way slower than mine" Whats the point?? Of course it is. Thats why I suggested comparing WMA to MP3PRO, the latest and greatest. I just feel that would be a more meaningful comparison. By your logic I could just as well compare a wav and an mp3 at equivalent bitrates and say one sounds worse, of course a wav is gonna sound worse at 128kbps than an mp3 will..did we expect any different? The fact is WMA is a low bitrate codec, around 64kbps, MP3 is higher, around 128 or so, other formats, like wav are even higher. So why bother putting them all at the same bitrate and comparing them?? I just dont see how its meaningful.
Seriously, this thing simply doesn't have the features to make it a really worthwile solution for portable MPEG4, your best option right now is a decent laptop. This is essentially an MP3 player with some extras thrown in. For starters the storage is extremely expensive, its small, and its slow, USB 1.1? puhlease... How about a hd with usb 2.0 or firewire or, maybe even better, cd rom. Secondly, most of the mpeg4 videos I already have are at too high a resolution to play on this so if I want to watch them I'm going to have to reencode..give me a break... And third it doesn't look like this thing has any sort of video out, so I'm stuck watching it on a miniscule screen..boring... The idea is great and for a first try its good, but to really be usefull theres going to need to be some serious improvement.
Yea it does. But WMA is a 64kbps codec, that is, it was developed with the intention of providing near cd quality sound at 64 kbps. MP3 is a 128 kbps codec, so of course it will sound worse than WMA at equal bitrates. Try comparing WMA to MP3PRO, a newer, 64kbps codec developed by the Fraunhoffer(spelling?) institute. I can't tell the difference between MP3PRO and WMA at equivalent bitrates. But comparing MP3 and WMA at equivalent bitrates and saying one sounds worse is like saying a jpeg of a picture looks way better than a gif of the same picture with an equivalent filesize, the two aren't even in the same camp so its fairly pointless.
