    If widely used, the GPL3 will change that. It is explicitly and methodically being written to be as anti-business as possible. Software released under the GPL3 will be avoided by all companies for any purpose. FOSS will become a hobbiest ghetto, with no commercial potential even for commercially useful software.

    As an aerospace engineer, I'm glad they are reverting to the apollo 'stack' concept. It is safer than the shuttle, in theory...

    Who's theory? I assume you've done a fault tree analysis? In comparing other launch systems with the shuttle, I've found that the theoretical differences in safety are fairly insignificant. Don't give me the "it's got an escape system" if you're not going to talk about what flight envelopes it can be used in (That capsule wasn't designed to separate in atmosphere and once it does it's flying backwards) and what other flight and pre-launch risks such a system adds (some).

    What existing man-rated launcher are you planning to use?

    I'm not saying there aren't engineering and efficiency advantages to expendable launch vehicles. There definitely are. Ability to send up equipment on a cheaper less reliable vehicle is a big one.

  3. Bullshit alert. on NASA Confirms Solar Storm Near 2012 · · Score: 4, Informative

    1.) Apparently, the Earth magnetic field has decreased by 10% in the last 150 years (source: http://www.space.com/scienceastronomy/earth_magnet ic_031212.html). I'm an electrical engineer and during my studies in particle physics, I learned that a particles velocity can be affected by magnetic fields. I believe it's possible that more of the Sun's radiation is penetrating the Earth's magnetosphere ( http://en.wikipedia.org/wiki/Earth's_magnetic_fiel d ) due to it being weaker. If more radiation hits the Earth, shouldn't that also increase the overall temperature of the Earth and can global warming be attributed to this?

    No. The total energy of charged particles impacting the upper atmosphere is tiny compared with the solar light energy Compare for example, the intensity of the aurora with the intensity of sunlight. Now add in the fact that the aurora covers a tiny fraction of the earths surface while sunlight blankets half of the earth at any time.

    Even if it were a significant amount of energy, this energy is entirely absorbed by the atmosphere at altitudes above 60km. You would need to come up with a plausible mechanism for transporting this radiation down into the lower atmosphere without increasing the temperature of the stratosphere.

    2.) Jupitor is experiencing the same climate change that Earth is.

    No, it isn't. The change on Jupiter is regional, not global. There is no indication that it is related to any solar phenomenon.

    3.) Mars is experiencing the same climate change that Earth is.
    No, it isn't. Mars is losing CO2 ice near its South Pole. The most likely explanation is that large dust storms from recent years dumped some dust on the ice causing it to absorb sunlight and sublime. This sublimation may cause warming by increasing the CO2 and H2O content of the Martian atmosphere. This might feedback into causing more ice to evaporate. Since there isn't an active carbonate silicate cycle on Mars due to lack of liquid water, there is nothing to prevent this from occurring. So it's likely that the Martian climate experiences warming of this type in a cyclical manner, and that the warming will continue until something else stops it. For example the reduction in the temperature difference between the poles and the equatorial regions might slow the winds enough that the dust storms stop allowing increased precipitaion of CO2 onto the poles. There is no equivalent mechanism at work on Earth.

    4.) The United Nations found that there is more Methane produced from livestock, which raises global temperature greater than CO2 by a factor of approx. 20

  6. Re:Anticipating "Shuttle sucks/Apollo great" comme on NASA Commemorates Space Shuttle Tragedies · · Score: 1

    Sorry fucktard - your "1-sigma" analysis is ignorant of the fact that Apollo had provisions for crew escape - in fact, for the whole command module to escape.
    I was going to call you an idiot, but that's an insult to idiots. My analysis does include the escape system. Only about a third of potential loss of vehicle accidents offer any chance of survival even with the presence of the escape tower system. (Notice that it was 30 crew for 15 loss of vehicle events, that means that 5 of the LOV events were survivable. Or is multiplying 3 by 15 too hard for you?)

    The escape tower does not help with reentry failures, failures in orbit, or catastropic failure near max-q (the most likely place for a structural failure during ascent). About the only thing it is really good for is loss of enough engines that orbit cannot be acheieved or catastropic failure at fairly low speed. It only works in certain flight envelopes where aerodynamic loads would not still destroy the crew module or make parachute deployment impossible. The reentry system isn't designed for every possible reentry trajectory, and once you use the escape tower you've thrown away the engines you need to adjust your trajectory. If you use it at hypersonic speed in dense air, once the escape rockets are spent, you've got an unstable body pointing in the wrong direction. It won't stay that way for long before it turns into a pinwheel. I highly doubt that the reaction control system on Apollo could have stabilized it.

    Before someone starts bemoaning how great and safe Apollo was compared to the shuttle, I'll say what everyone will subsequently ignore:

    If the Apollo program had gone to 117 launches, the best (max likelyhood) estimate is that there would have been 15 loss of vehicle accidents with 30 crew lost. While the error in that estimate is large, there is no evidence that Saturn launch vehicles were any safer than the shuttle, and it's a better than 1-sigma bet that they would have been worse.

    I agree that is what the license says. However, the GPLv2 does not anywhere, that I can see, allow you to prohibit distribution under another version, if you were granted that option, without the consent of the copyright holder. You may choose to distribute under the terms of GPLv2, but that doesn't mean you can restrict distribution under GPLv3 if the source you received says "GPLv2 or later"

    GPLv2 code could be merged with v2orlater code safely - it just needs to be released under v2.

    I'm not sure that is true. The if the license terms of some code are "v2 or later" and someone tries to release it "v2 only" that's a violation of the original license. The license explicitly says that you may only distribute it by giving the recipient the same rights as you recieved. In other words, if you received the right to distribute the code under "v2 or later" you MUST give anyone who receives the code the right to distribute under "v2 or later." "v2 only" violates that license. You can't change the terms of the license without the consent of the copyright holder. In other words, it is the choice of the recipient as to which version of the GPL they choose to receive it under, but my understanding is that a redistributor cannot choose which license they distribute under. They must give the recipient the same terms (i.e. choice) that they had.

    Only the copyright holder can choose to change those terms. If you don't hold the copyright you cannot change "v2 or later" to read "v3 or later" or to "v2 only".

    If Sun chooses "GPL v3 or (at your option) any later version", that pretty much kills that possibility. Linus's choice of "GPL v2 and no other version" is not compatible with "GPL v3 or later." It's unclear to me whether "GPL v2 and no other version" is even compatible with "GPL v2 or later." Probably not, because by including "2 or later" code into a "only 2" product can't be done without changing the license terms of the "2 or later" code without the permission of the copyright holder.

    Umm, yes they did. You have to watch your inclusions here. "v2 only" is a subset of "v2 or later". Also note that the "v2 or later" language is not actually part of the license (or a license type itself); it's just a phrase that is traditionally used to introduce the license in many releases.

    Sorry, I think you're wrong about that.

    GPL requires that the license terms (i.e. "version 2 or (at your option) any later version") be present in the copyright notice. If you don't own the copyright, you aren't allowed to change the licensing terms. Essentially, if people submitted code while the copyright notice read "v2 or later" you are allowed to distribute that code under v2, but you are not allowed to prohibit distribution under v3 or later.

    It's difficult to overstate how strong the ramifications of that "or any later version" clause are. For all intents and purposes, including that clause when you license your code is the next best thing to assigning copyright of your code to the FSF, since it allows them to re-license your code as they see fit.

    No it doesn't. The choice of license is up to the recipient not the distributor. Suppose have a piece of software that I wrote and distribute which is licensed under the "version 2 or (at your option) any later version" clause. Suppose the FSF releases GPL version 4 which states that the recipient must send $100 to the FSF in order to use the software. What person in their right mind, upon seeing "version 2 or (at your option) any later version" is going to choose GPL version 4? No one, that's who.

    And as far as I can tell, no one at FSF can take code to which I own the copyright and modify my copyright notice to read "version 4 only." The GPL allows the recipient of software to choose the terms of a later version or the earlier version, but it does not allow the right to choose the earlier version to be restricted. Modification of the software is allows, modification of the licensing terms is not. Even if the GPL is changed to allow modification of the licensing terms, versions will still be available that say "version 2 or (at your option) any later version".

    From what I know of physics, ice sticks out of the water as much as the density of the ice is less than the water around it. (10% or so) So when the ice melts, shouldn't the sea level stay the exact same?

    It would if the salinity of the water and the ice were the same. In this case the salinity of the ice is less than the salinity of the ocean. Lower salinity means lower density and lower volume. Melt the ice and the salinity of the ocean ends up lower, so the density ends up lower, and the volume increases, raising sea levels.

    It's not as big an effect as it would be melting ice lying on land, but it is an effect.

    It's temporarily offset by the effect of the ice cooling the surface waters (which makes them more dense), but that effect doesn't last. The salinity effect takes much longer to fix.

    Lower salinity has problems of its own. The lowered salinity of the arctic ocean could also affect ocean currents by preventing low salinity cold water at the poles from sinking into the more saline deep ocean. The big fear for Europe and the U.S. is that this might shut down the atlantic conveyor system (i.e. the gulf stream is a part of it). If that happens, Europe will get really cold, and tropical waters will get warmer. It would probably resemble another mini-ice age. A cold Europe would challenge world food supplies.
