    Sage as opposed to magma, maple, mathematica

    There's SymPy as well for symbolic mathematics.

    Science f.lux: Prevent your computer monitor from ruining your circadian rhythm

    I've been using the program for two days now, and while I don't know about the sleep thing yet (I've got kind of a messed up sleep rhythm as it is, right now, and two days just isn't much of a sample size), it's definitely more comfortable looking at a dimmed monitor in the evening. I recommend it.

    Project "Dwarven Skyboats" (fun fantasy spacecraft) - suggestions still welcome

    Lose the wood completely. What are you, an elf-hippie? :lol: The cockpit at least should be all stone, metal and precious gems. (I may actually have to dig up Dwarf Fortress again just to build that ship on a launchpad...) Edit: Oh, and if I remember Dwar Fortress correctly, this needs tons of...

    Project G42-200 StarLiner

    I had the invisible ship thing when I ran the G42-200 on Orbiter 2010. After I upgraded to Orbiter 2010 P1, it worked.

    Project G42-200 StarLiner

    I think it doesn't really matter. If something goes catastrophically wrong during any flight phase, the only real option you have is to preserve the craft at all cost. During launch and reentry, even the tiniest leak would probably rip the craft apart (see Columbia). If you'd have to "bail out"...

    Personally, I'm against helmets. You only have to have a helmet in case of a cabin atmosphere leak, and that cockpit looks like it should be a shirt-sleeve environment anyway. (You could compensate for a leak anyway by just blowing in air at the same rate until you fix it. If you can't do that...

    You need to mentally insert some smilies into my post.

    Ever heard the term "lithobraking"? Couple that with the motto "every landing you can walk away from is a good one" and you've got something going.

    Discussion Powell & Pelligrino's Skytrain (aka ISV Venture Star)

    Well, yeah, but how is that fun? :lol: (I just had the mental image of holding onto one end of the craft and swinging the whole thing around like, say, a stone on a string. I can't figure out how to make that practical for turning the whole thing, though.)

    Discussion Powell & Pelligrino's Skytrain (aka ISV Venture Star)

    The design is good for basic "forward" flight, but I see problems when you want to go anywhere else. The cable you're proposing would be subjected to significant shear strenghts if you just slapped a RCS thruster on either end and began turning the ship, so I imagine a solution would be to...

    Ringworld type object...

    If I remember correctly, though, for the structure as discussed in the books you'd need materials that have tensile strengths in the order or magnitude of nuclear forces. It would probably be worth doing a quick calculation and finding out if this is true for your structure, as well.

    You can't take cupholders too seriously. It's a law of nature. Having good cupholders is, like, the most important thing on a spacecraft, yaknow? :lol: :hailprobe: (and cupholders)

    What do the SAS switches underneath the flight control stick do?

    Project G42-200 StarLiner

    In keeping with the whole glass cockpit thing, a diagnostic page on the EICAS would, perhaps, do the job as well. Then again, when you have an onboard computer malfunction, that page would probably be unavailable, so I vote warning lights panel for at least the major subsystems. Also, I've just...

    Project G42-200 StarLiner

    I agree- in that case, the wingtop would be the best solution. As far as looks go, sticking a radiator out under the rudder would look good, I think, but then you'd have it in the way of on-orbit engine firings, which could lead to much Fun :lol: Lots of switches? Me likes. As long as the...

    Project G42-200 StarLiner

    As far as the radiator goes, why not use that ridge in front of the rudder? I imagine having some sort of fin sticking up- you'd have only one moving part, the radiator itself, and it would not radiate back on the ship too much. Of course, the practicability of this approach depends on how you'd...
