NASA Taking Ethernet Into Deeper Space

coondoggie writes "While Ethernet technology has gone places no one would have envisioned 36 years ago, NASA today signed an agreement with a German Ethernet vendor to build highly fault-tolerant networks for space-based applications. TTTech builds a set of time-triggered services called TTEthernet that is implemented on top of standard IEEE802.3 Ethernet. Its technology is designed to enable design of synchronous, highly dependable embedded computing and networking, capable of tolerating multiple faults, the company said."

      For twelve years, you have been asking: Who is John Galt? This is John Galt speaking. I am the man who loves his life. I am the man who does not sacrifice his love or his values. I am the man who has deprived you of victims and thus has destroyed your world, and if you wish to know why you are perishing-you who dread knowledge-I am the man who will now tell you.' The chief engineer was the only one able to move; he ran to a television set and struggled frantically with its dials. But the screen remained empty; the speaker had not chosen to be seen. Only his voice filled the airways of the country-of the world, thought the chief engineer-sounding as if he were speaking here, in this room, not to a group, but to one man; it was not the tone of addressing a meeting, but the tone of addressing a mind.

      "You have heard it said that this is an age of moral crisis. You have said it yourself, half in fear, half in hope that the words had no meaning. You have cried that man's sins are destroying the world and you have cursed human nature for its unwillingness to practice the virtues you demanded. Since virtue, to you, consists of sacrifice, you have demanded more sacrifices at every successive disaster. In the name of a return to morality, you have sacrificed all those evils which you held as the cause of your plight. You have sacrificed justice to mercy. You have sacrificed independence to unity. You have sacrificed reason to faith. You have sacrificed wealth to need. You have sacrificed self-esteem to self-denial. You have sacrificed happiness to duty.

      "You have destroyed all that which you held to be evil and achieved all that which you held to be good. Why, then, do you shrink in horror from the sight of the world around you? That world is not the product of your sins, it is the product and the image of your virtues. It is your moral ideal brought into reality in its full and final perfection. You have fought for it, you have dreamed of it, and you have wished it, and I-I am the man who has granted you your wish.

      "Your ideal had an implacable enemy, which your code of morality was designed to destroy. I have withdrawn that enemy. I have taken it out of your way and out of your reach. I have removed the source of all those evils you were sacrificing one by one. I have ended your battle. I have stopped your motor. I have deprived your world of man's mind.

      "Men do not live by the mind, you say? I have withdrawn those who do. The mind is impotent, you say? I have withdrawn those whose mind isn't. There are values higher than the mind, you say? I have withdrawn those for whom there aren't.

      "While you were dragging to your sacrificial altars the men of justice, of independence, of reason, of wealth, of self-esteem-I beat you to it, I reached them first. I told them the nature of the game you were playing and the nature of that moral code of yours, which they had been too innocently generous to grasp. I showed them the way to live by another morality-mine. It is mine that they chose to follow.
