  1. Re:Didn't this happen with the USSR? on NASA Was Prepared to Silence Stranded Moon Astronauts · · Score: 1

    This sounds a bit stupid to me (or maybe it is just misreported). But how the hell can someone fall towards the sun just by skipping off the atmosphere? It takes one hell of energy to get to escape velocity, that sure doesn't happen to you by accident.

  2. Re:Consider this... on NASA Was Prepared to Silence Stranded Moon Astronauts · · Score: 1

    > (Armstrong was dangerously low on fuel when he landed; Another minute more, and he would have had to abort the landing)

    They actually landed 20 seconds before they had to abort.

  3. Re:Contact on NASA Was Prepared to Silence Stranded Moon Astronauts · · Score: 1

    Not true. NASA had one man accidentally exposed to near vacuum on earth during a space suit test (he is fine). They also have a web page on medical implications of vacuum exposure (sorry, don't have the URL handy right now).

    Actually, for foaming to occur this would require extreme loss of pressure *inside* your body. This would require that your body increases its volume quite much. We know our bodies aren't inflatable balloons, they would explode and we know they don't explode.

  4. Re:Who knows... on NASA Was Prepared to Silence Stranded Moon Astronauts · · Score: 1

    The other way round: the speed of sound in thin air is slower. It nature it is fastest at sea level and a hell of a lot faster in solid objects. Think of it this way: in low density the molecules have to travel a long way to hit the next molecules in order to transfer sound.

  5. Re:No. on NASA Was Prepared to Silence Stranded Moon Astronauts · · Score: 1

    The Sovjets did most of their early space missions (or, better, attempts) in secret and never told the public about failures and deaths. But they had it a lot easier in hiding rocket starts / explosions with their vast uninhabited lands. Censoring took care of the rest. For them dying in an attempt to reach space was obviously not a heroic thing.

  6. ESA manned missions on NASA Was Prepared to Silence Stranded Moon Astronauts · · Score: 1

    The ESA has no manned rockets. The rockets in use are all different types of Ariane and unmanned. There were plans for an European space shuttle ("Hermes", IIRC) but it got discontinued.

    This does not mean that the ESA has no manned space program at all, they just send their astronauts up in cooperation with Russia (to MIR) and with NASA (e.g. the Spacelab module was an European project and twice in space with the Space Shuttle). They also contribute one module to the ISS.

    If you mean changing the From: header, mutt allows this.

  8. Re:True, but... on Bright Star Getting Brighter · · Score: 1

    Perhaps because the existence of Tachyons has never been proved by anyone except by people that went beyond incredibility long ago?

  9. Int'l Netscape SSL enhancement on Germany Frees Crypto · · Score: 2

    You can upgrade the international versions of Netscape to high grade encryption using Fortify, which is developed outside the US. No need to be stuck with 40 bits.

  10. Re:Win95 added crashability (a little off topic) on Linux 2.2 DoS Attack · · Score: 1

    This is known for long. Win95 (and 98?) count time as milliseconds since boot in a 32-bit variable. If you do some calculations you will find out that it will wrap around after 49.71 days.

    For a comparison: Linux counts hundredths of seconds (except on the Alpha, where it too is ms but 64-bit) and will therefore last ten times longer until wrap around. However, kernel code is expected to survive a wrap and debugging is done in this area (like setting the timer variable to a few minutes before wrap at boot time and see where problems arise - 2.2 should have eliminated most of them).

  11. Re:Prototype = function testing on CPU Cooling Insanity · · Score: 2

    I don't think that if this is standard sometime in the future it would have complete MBs under coolant. If liquid cooling is required in the future (looks like that), probably the motherboards would change and everything that emits heat (CPU, RAM, graphics?) would be seperate and then put into a cooling box. After all, not everyone wants a fridge on his desk :-)

  12. Re:Water kicks butt, but.. on CPU Cooling Insanity · · Score: 1

    That would have the problem that it wouldn't work everywhere. Especially not in the Kremlin.

  13. Re:Hard drives are NOT sealed on CPU Cooling Insanity · · Score: 1

    The point is that there is no seal to break but that harddrives do have an opening for pressure acclimatisation. However these have long winded canals for dust filtering, the question is if something with the viscosity of oil would actually get in (consider that the would have to get out through the same opening to let the oil in).

  14. Re:Translation on Linus To Recieve Honorary Doctorate · · Score: 1

    Debian comes with this program (called "chef") in the "filters" package.

  15. News? on U.S. Using Key Escrow To Steal Secrets? · · Score: 2

    This is news? Only because it concentrates on key escrow. It is known however that intelligence agencies are used to spy on foreign industry and to use the information to help local companies. They have to be of some use after the cold war has ended, after all.

    Remember ECHELON? Was on /. a few days ago. There's a sort of funny story about that. A European (would have to look up whether it was German or Netherland) firm were sued by an US company over a patent they registered earlier. When the European company asked for the paperworks on that, they got some of their own internal fax communication that was eavesdropped. The agencies didn't even bother to remove the original company logo. IIRC the European company even lost in court...

  18. Re:How long would a PC and a couple of these need? on Shamir's new Crypto Gadget · · Score: 1

    TWINKLE attacks by factoring. This is useful for most asymmetric algorithms but not for symmetric algorithms which do not use primes maths. My estimate for the PII 300 (and in that case it doesn't really matter much whether it's a 5GHz or a 50MHz) would be a couple of million of years for 128 bits. Only, of course, if trying all keys is the easiest way to crack the encryption.

    Look at distributed.net, trying to crack a 64 bit key for 558 days now. Checked only 7.9% so far. And remember, 65 bit takes twice as long, and 66 bit twice as long as 65 bit...

    Oh wait, I just run the numbers through bc: 128 bit has 340282366920938463463374607431768211456 possible keys, if we check 1 million keys per second, we would need approximately 5395141535403007094485264577495 years to find the key. Have fun.

  19. Re:Factoring technology on RSA slightly broken · · Score: 4

    No, there is no known plaintext. You don't encrypt the message, you encrypt a key for conventional cryptography and encrypt the message with that one. And the key you encrypt is (and should be, or you have a problem) a random number of which nothing is known about by an attacker.

  20. Re:What about frequent flyers? on Total Recall Weapon Scanner a Reality · · Score: 1

    Frequent flyers fly frequently and therefore get a lot cosmic ray pollution anyway (they said the scanning is equivalent to about 1 hour flight). But yes, it's still an increase.

    And I don't think flight personnel pass through several scanners a day because there is no checking inside the security area. Unless they go to the hotel for the night they usually stay inside.

  21. parport mp3 decoder on Do it yourself MP3 Stereo · · Score: 1

    The German computer magazine c't will have a description, board layout etc. of a hardware mp3 decoder that hooks up to the parallel port in their next issue. They claim it works with 80286 and even XTs. Sorry, don't have more info yet.

  22. Why lasers? When mini-LCDs are far better? on Laser-based Virtual Retinal Display · · Score: 1

    Yes, why? Maybe because direct projection gives higher resolution, sharper picture, better contrast, better colors, less power consumption (I'd guess) and doesn't need lenses to correct the short distance between eye and display?

  23. mind control on Gates: "Linux will have Limited Impact" · · Score: 1

    Anyone noticed that M$ ceases to mention their "superior" technology? Now it's all about the consumers, and Gates knows, no, defines what "the consumer" wants. FUD at it's best, addressing the laziness to try something new, giving the cozy feeling that this is the standard way to do it. Because this is what you want. You want that, get it? No denying.

    He's getting desperate, isn't he?

  24. Hackers vs. Crackers on "Hackers" Really are Anti-Social Geeks · · Score: 1

    So what then? When "hacker" refers to a cracker, how does one refer to a hacker? It causes annoying confusion. Sure, you can not expect everyone to know it, but if there is confusion you can explain the difference between a hacker and a cracker. Simply accepting the media's choice of calling crackers "hackers" leaves you no way to communicate on that subject with anyone who is polluted by the media definition.

    And probably it will be successful some day. I already notice in the German magazine c't that they slowly get the terms right (not everytime, but it increases).

  25. 2 GB? I thought it was 8GB on D.H. Brown Associates Attacks Linux · · Score: 1

    They won't mangle the VMM, but Linus agreed to incorporate future patches to use unmapped memory as ram disk, which would not create an ugly, unmaintainable mess in the source code.
