OK let's say NASA loads up the shuttle with a dozen people and has daily launches year-round. That's 4383 persons launched per year. Let's say that only 1 in 100 U.S. citizens both is physically capable and wants to go. The CIA gives the US population at 298,444,215. In order to launch 1 in 100 US citizens at that rate would take 681 years. 298444215 / 100 / 4383 = 680.9 Your turn may take a while..
So in order to receive and listen to some streaming audio: receive buffer -> decoder -> buffer -> deinterleaver -> buffer -> sample rate converter -> buffer -> process mixer -> buffer -> device mixer -> clipper -> float to int -> buffer -> device
Single-stage, 1-bit sigma-delta converters are in principle imperfectible. We prove this fact. The reason, simply stated, is that, when properly dithered, they are in constant overload. Prevention of overload allows only partial dithering to be performed. The consequence is that distortion, limit cycles, instability, and noise modulation can never be totally avoided. We demonstrate these effects, and using coherent averaging techniques, are able to display the consequent profusion of nonlinear artefacts which are usually hidden in the noise floor. Recording, editing, storage, or conversion systems using single-stage, 1-bit sigma-delta modulators, are thus inimical to audio of the highest quality. In contrast, multi-bit sigma-delta converters, which output linear PCM code, are in principle infinitely perfectible. (Here, multi-bit refers to at least two bits in the converter.) They can be properly dithered so as to guarantee the absence of all distortion, limit cycles, and noise modulation. The audio industry is misguided if it adopts 1-bit sigma-delta conversion as the basis for any high-quality processing, archiving, or distribution format to replace multi-bit, linear PCM.
The last time I was there I could have gotten a (counterfeit) North Face coat, Rolex watch, and Prada bag, and for about $100US.
you paid way too much.

X-43A Hits Mach 7
·
· Score: 4, Informative
It was taken to mach 5 by the Pegasus, then it accelerated under the scramjet to mach 7
This is not true. The pegasus booster took it all the way to mach 7. The scramjet proved it could make positive thrust, but it did not accelerate, it actually decelerated during those 10 seconds. Maximum speed was at booster burn out. This is according to their press conference yesterday.

According to their press conference yesterday, the maximum speed was attained at booster burn out. The scramjet achieved positive thrust, but it was decelerating the whole time (10 seconds). The speed was therefore the result of the booster and not the scramjet.

Yeah, GWB is printing it right now on presses made in China, bought with money borrowed from China, in order to pay back China.
PATIENT: How am I doin' doc?
DOCTOR: The good news is you successfully pooped out the wormbot. The bad news is.. we think it laid eggs.
So in order to receive and listen to some streaming audio:
receive buffer -> decoder -> buffer -> deinterleaver -> buffer -> sample rate converter -> buffer -> process mixer -> buffer -> device mixer -> clipper -> float to int -> buffer -> device

SACD is freaking the best digital sound format on the market AND it's 1 bit (DSD). How cool is that?
not too cool.
Why 1-Bit Sigma-Delta Conversion is Unsuitable for High-Quality Applications
Single-stage, 1-bit sigma-delta converters are in principle imperfectible. We prove this fact. The reason, simply
stated, is that, when properly dithered, they are in constant overload. Prevention of overload allows only partial
dithering to be performed. The consequence is that distortion, limit cycles, instability, and noise modulation can
never be totally avoided. We demonstrate these effects, and using coherent averaging techniques, are able to display
the consequent profusion of nonlinear artefacts which are usually hidden in the noise floor. Recording, editing,
storage, or conversion systems using single-stage, 1-bit sigma-delta modulators, are thus inimical to audio of the
highest quality. In contrast, multi-bit sigma-delta converters, which output linear PCM code, are in principle
infinitely perfectible. (Here, multi-bit refers to at least two bits in the converter.) They can be properly dithered so
as to guarantee the absence of all distortion, limit cycles, and noise modulation. The audio industry is misguided if
it adopts 1-bit sigma-delta conversion as the basis for any high-quality processing, archiving, or distribution format
to replace multi-bit, linear PCM.
I didn't know there were major highways with automobiles running around on them back when the lights first were seen...
It can be explained by road lights even back in the 1880s. Horse drawn carriages carried lanterns when driving at night.
"The entire coach was dark red with lanterns near the front to help while driving in the dark."
Old timey looking lighting fixtures selling today still go by the name "carriage lantern" or "coach lantern". Google for it.
