  1. Those poor people, living in a world of paranoia and superstition. May the light of reason one day reach these dark corners of their minds.
  2. You shouldn't have to go into the .cfg to switch a flag that has a button. As for whether Unity might break GDPR, half the reason big companies have all those lawyers is to stay out of trouble. The other half is for when they get into it anyway, and it happens all the time. Usually it's user forums where problems like this one are discovered. A good company will read about and fix the problem before the media does.
  3. Thanks for the replies! You have persuaded me not to add the card unless I encounter bottlenecks years from now. In response... 1) I would add the graphics card myself but would need to move bundles of cables that were zip-tied together and secured to the case by Geek Squad when they upgraded my rig years ago. I might also need to move the hard drive and its cables, because the card would reach from the back of the tower to the front. I am not confident in doing this. 2) My power supply is 1,200 Watts. If it would not have enough power, then I doubt I could find a bigger one,
  4. Hey Forum, I found a graphics card on one of my shelves and want to install it alongside my current one to improve my game performance. Although the graphics cards are slightly different, precluding a bridge, I have read that DirectX12 lets game developers work around this problem by building games that can use several different graphics cards at once. Would installing the second card be worthwhile? Technical Details: -Current Card: GeForce GTX 780Ti 4GB -Found Card: GeForce GTX 780 3GB -Installation Cost: $40
  5. Thanks! Launch profile matters for all systems going beyond LKO, but I see your point. I meant, and my thesis turned out to be, that improving design can only improve cost per ton to the limit imposed by the payload and mission profile. This limit can be called the theoretical upper bound on the efficiency of any rocket system, whether for lifting or transit. Now that I think about it, we could state generally that the maximum efficiency of any engineering project with well-defined theoretical principles is given by applying them to the constraints of the project. In Ker
  6. We can and should define this problem more abstractly. The cost per ton of a launch system equals the amount of money spent, per launch, to lift one ton of payload along a desired launch profile to a desired orbit. These latter two constraints are important because they prevent payloads from being launched by very cheap but very weak lifters, whose cost would approach that of fuel with increasing payload regardless of whether the system were recovered or air-breathing or not. Therefore, we must state the theoretical lower bound of efficiency in two lines rather than one. The first li
  7. Stratzen, are you around?  Please respond. :(

  8. Dear Forum, Why was the founder of Lavabit, an encrypted email service company against which the United States government had obtained a search warrant in pursuit of the whistleblower Edward Snowden, not found in contempt of court and ordered to restore Lavabit after he defiantly shut it down? Although I deplore the whole affair of mass surveillance, I also cannot ignore that the government appeared to have legal means to pursue him personally for his services or, should that pursuit have failed, publicly punish him for opposing its agenda. Therefore, I seek the knowledge of better-read
  9. Hey, Strat, I'm sorry for having not replied to you earlier.  I shouldn't have procrastinated.  Do you still want to make Atlas with me?

  10. I never thought about the possibility of Kerbal nuclear weapons until now, so I figure Kerbals are peaceful. But they're still kerbal: it's easier to list the things they haven't blown-up!
  11. Of course the kids are always innocent: the adults are responsible for them in every case. -Duxwing
