    Since most of the replies so far have either been disparaging or been references to other scifi works, I will do my best to actually answer your question.

    For the sake of accuracy, I am going to assume the following:

    The mission is 1 way.
    There will be no resupply operations.
    The colony must supply itself with infrastructue and supplies.

    That out of the way, here it goes.

    First, your crew must be over 500 people, and totally unrelated to each other. This is the bare minimum required for a stable breeding population. Any smaller, and you end up with an unviable population, a la the nazi eugenics colony experiments.

    Your crew cannot all be officers, administration, tech heads, et al. You positively have to include blue collar workers. Machinists, assembly workers, etc.

    In addition to this, you cannot presume to find food on the planet you are sending the colony ship to. At our distance from the nearest goldilocks planet, we can't even get a gross atmospheric spectrograph, let alone a detailed list of possible lifeforms. This means you have to not only take whatever food your mission needs for the trip through space, but also the means to produce food when you get there. Frozen domesticated animal embryos, collections of edible seeds and plantforms, etc. The works. It also means you have to take horticultural experts and farmers with you.

    In addition, there is a lot that can go wrong on such a mission. The colony ship will be in transit for over a hundred years to reach the nearest starsystem using the fastest possible forms of propulsion currently available to us. This *will* be a multigeneration voyage, and shit breaks. You have to be able to fix things and make spare parts. That means you need a complete factory and refinery complex built into the colony ship.

    In short, think of a space vessel with the combined cubic footage of new york state, comprising manufacturing, housing, environmental, and food cultivation systems, in addition to propulsion, power generation, water reclamation, and administration systems. You will be launching a small country into space. If it isn't at time of launch, it will be by the time it reaches its destination.

    The colony ship will be too large to land on the destination planet. It will need small craft to deposit transplanted lifeforms, colony site construction equipment and supplies, and ground personel on the surface. These craft need to be reusable. The colony ship would BE the supply line for the new planetary colony site. It would stay in orbit, produce and deploy any gps or com system satelite networks, and ensure the viability of the ground based colony as it develops.

    In addition to the lander craft, the colony ship would need service and resourcing craft to help keep the colony ship operational. The ship would be too large for unassisted spacewalks for repairs, so some form of space only maintenance and cargo tug craft would be necessary as well.

    This means the colony ship needs cargo bays, and docking bays, distributed around the ship.

    Due to the size of the ship, some form of internal rapid transit system for the crew will be necessary.

    The psychological integrity of the hermetically bottled colony ship population needs to be maintained. Recreational fascilities need to be available, including botanical gardens which serve no other purpose. (This means you need people to maintain them. Some bit of crossover in functionality can be possible with the horticultural experts developing new domestic plant varieties enroute in the botanical gardens.) It needs musicians, artists, poets, movie stars... the works.

    The colony ship has to contain epic shittons of water and biomass. It has to be able to reliably handle a growing population while in transit without overloading the environmental systems. It also has to be able to deflect cosmic energy for hundreds of years.

    The colony ship has to produce artificial gravity. This means it has to rotate in some fashion, as no other means of simulating gravity is currently known.

    If you are going to write a story about such a voyage, you have to explain how the earth managed to fund such an operation, and also why they did it.

    Those are the two most commonly used aluminum alloys used in aerospace fabrication (I make prints citing them all the time at work), and for strength reasons these need to be heat treated in most circumstances after being formed or milled. A powder or paste based prototype printer just won't be able to produce these alloys, because the desired mechanical properties are a result of the metalurgical crystaline structures present in them after annealing and heat treating. That is, unless you want to ship a whole annealing oven and solution heat treatment system up there... (just so you know, that equipment isn't light.)

    For composite materials, conventional heat shaped plastics are not common either. Usually a thermally cured resin material is used, such as with phenolic, or with carbon fiber composite. Doing thse in space would be a nightmare, since not only do you deal with a sticky, honey like liquid with toxic fumes, and the curing oven, you also need a vacuum bag machine and the finished product must be sanded, creating tiny (toxic) particles to float around the ventilation system.

    I could see a prototype maching puking out ceramic paste parts prior to electric kilning, or plastic parts, but not the main structural parts made from alloy or composites.

  13. Re:Still impossible on Corporate Claims On Public Domain YouTube Videos · · Score: 1

    1) not quite correct again. I proposed submitting a recording. The definition of which is left purposefully ambiguous by the copyright office, to avoid excluding new technologies. Digital recordings are included in this class, which then includes computational representations. Eg, an mp3 file is a series of instructions for the decoder to produce a sound. It is not itself, a direct or static copy of that sound per se, but is classified as such for the convenience of the legal system. Other such representational formats are .mod, .mid, etc. It is possible to create such a digital recording that is of infinite length. The requirement for an infinite length was a rhetorical one, to fit your contrived use case. The reality of the situation is that you would have an infringement basis, using prior case history, with a far reduced subset than what you postulated: every possible combination of 4 measures of musical notation would be more than sufficient, and is considerably smaller than the rhetorically astronomical sample that you postulated in your first rebuttal. My counter argument was that even under the conditons you specified, your argument doesn't hold up.

    The definition you quoted, "a computer program that produces that output" is exactly manifest by a .mod or .mid file. Further, it also has a graphic art analog in the form of a truetype font, which is a bytecode program for how to deform and display a series of closed quadratic curves. A font is both the printed output, and the program which generates that program. Both are subject to copyright protection. The logic inside such a file would be quite simple, and would defacto BE such a recording, despite your objection to the contrary. I am citing industry standard formats for phonorecordings that happen to have such protections, and which satisfy the requirements, yet you continue to assert that they don't apply, for nebulous and unstated reasons.

    Now, your "does not promote" argument: the program can be part of say, a scientific analysis of the music space, in terms of human cognition. A complete but truncated example of that space (every possible combination of 4 measures) can be experimentally interesting to see what proportion of that space humans would consider music. This has obvious applications for determining how much of the useful space is allready allocated to copyright, and if current copyright is a reasonable solution or not. As a "purely serendipitious" (ahem) consequence of that sampling, the generated work would be impossible to avoid "copying" from, due to the nature of the work.

    If I made such a study for money, would I not be correct in pointing out the obvious utility that copyright would offer to finance additional research? Also, by giving such a test case, do I not essentially torpedo your claim that the sequence has no intrinsic merit for which copyright would apply?

    Your arguments against a static copy are torpedoed by the contrived requirements you assert as being extant: 4 measures of 4:4 time would at most, at fullest extrapolation, be a few gb in size. I could submit the recording on a usb hdd as the physical volume, and still have the desired effect. I don't have to compute entire works for there to be infringement, as established by prior court precident.

    Again, not required if using a proceedural file format, like .mod

    Your argument at this point is one of an appeal to authority argument "the copyright office won't let you, but I refuse to cite any prior case history. You are just wrong, stop talking."

Playing them as raw pcm would result in noise.
