Once you realize that your voice is just like your e-mail, your IM, your web traffic... it's just data! Why not route it like the rest of your data?
It isn't "just data". There are quality of service and reliability issues to be considered. TDM gives me low and predictable latency, guaranteed bandwidth, and an infrastructure that has extensive reliability features and ways of routing around congestion and damage.
VoIP has lower costs, less reliability, "best effort" delivery.
Many years ago, a friend had a GM car with a nasty design defect. The motor mounts would break, the engine would flip over, jamming the accelerator and disabling the power steering and brakes. When it happened to him, my friend had enough presence of mind to turn off the ignition. From what he told me, this defect had caused many accidents, due to drivers freaking out and losing control of the vehicle. Many people just don't react well to everything going wrong at once.
Didn't they also have some user interface problems on their flight management system and autopilot? I remember watching some demonstrations of how the system could confuse a pilot and end up doing something very different than what was intended by the pilot.
Airbus also seemed to be very quick to blame all incidents on pilot error, before all the facts were in.
NASA does a lot of stuff with geodetics. laser ranging of satellites and the Moon, mapping planetary gravity and electromagnetic fields, upper atmosphere research, remote sensing, movement of the Earth's crust, etc. It's all planetary science, with the Earth as its subject.
The magazine "American Heritage of Invention & Technology" has an interesting article in their current issue on the first transistor radio (see here). It was designed by Texas Instruments and built by Regency. Although the cost was high, $50 was real money in 1954, Texas Instruments only broke even on the product. They were breaking a lot of new ground in the mass-production of transistors and printed circuit boards. That helped them become a leader in the semiconductor industry, where they have made a great deal of money. A little Japanese company, later renamed to Sony, soon followed in 1955 with their own transistor radio.
The problem is that the vehicle doesn't have the speed/energy needed to put itself or anything else into orbit. It's like the first American suborbital manned space flights that used the Redstone rocket. See this for a complete explanation.
Most modern chips have 64-bit or 80-bit floating point hardware. Single precision (32-bit) floating point is not any faster than double precision (64-bit) floating point in most cases. The use of double precision provides an extra cushion against some of the accuracy and stability problems that can afflict code written for single precision.
There are some algorithms and applications where a larger word size can result in major performance improvements. It isn't all marketing bullshit. That said, my major complaint with current processors is their memory latency and bandwidth. Any cache misses and performance goes straight to Hell.
It wasn't a general anaesthetic. I was still conscious during the procedures. I just don't remember any of it. I believe they called it twilight anaesthesia.
You need better drugs. I had an endoscopy and colonoscopy in the hospital and I don't remember anything between getting an injection and waking up in the recovery room.
Most of the energy from the most powerful nuclear weapons was derived from the fission of the bomb jacket, composed of U235 or U238. I don't have any numbers handy, but I believe they were pretty efficient at "burning" the lithium deuteride used as the fusion fuel.
Humphrey was a serious candidate well before the assassination of RFK, he wasn't a replacement for RFK. RFK was shot on the day of the California primary, before the Democratic convention. George Wallace, a third party candidate, received about 13% of the popular vote and won the states of Alabama, Arkansas, Georgia, Mississippi and Louisiana.
I wouldn't call classic digital TDM packet switching. A frame is not a packet, it's a container for a fixed number of channels. The channels get routed, not the frames.
I would suggest writing down the pass phrase, sealing it inside a double envelope, and storing it in a safe. That way, they can get it if they need it, but it is also obvious when it has been disclosed to someone other than the account holder.
There is a huge, huge difference between flying to 100 km and achieving low-Earth orbit (LEO). SpaceShipOne has about 2% of the energy needed to reach LEO.
As a software designer, I'm wondering what's the point of "tens of gigabytes" of HD storage.
I'm assuming that each console has a reasonable amount of flash memory, say 512 MB from looking at current prices. That's enough for tons of saved games, patches and added features.
The game disk has 9 GB of space, assuming dual-layer DVD. If that isn't enough, the game could be split onto two DVDs.
How many of my customers have Internet connections, have their console connected to the Internet, and have a broadband Internet connection? If I want to release a major expansion pack, it's going to be on a retail packaged DVD, along with the current and tested version of the game. So what use is that "tens of gigabytes" of HD space? Don't say that it's for copying pirated games to the hard disk.

That's why we have trade secrets, which have the advantage of not being time limited.
Where did they say "dollars"?
It's not all rocket-ships and astronauts.
I mean the speed of electromagnetic radiation, not electrons. Which is in the neighborhood of 0.6c in coaxial cable.
Which is faster?
Congress had passed enabling legislation in the form of the All-Channel Receiver Act of 1962.
I'm impressed. We're having a special today, would you like to shoot your other foot?

A cable modem is a modem. Modems are not limited to operating on voice-grade telephone lines.
The 486SX sold so well that Intel made a new mask that removed the FPU entirely. This increased the yield per wafer.
