  1. 5/10. A pioneer of rocketry, but bears the dubious distinction of being a weapon that killed more of its builders than it did the enemy.
  2. Decided to start work on a sensible Moho mission, it being one of only three places (along with Dres and Vall) I haven't landed on. OK, "sensible" is relative. I'm in for some long ion burns, but at least I shouldn't run out of delta-V! The lander is inspired by the Russian LK Moon lander, being a single stage but with the landing legs to be left behind on the surface. It fits, just about, in a 2.5 m fairing.
  3. As many others have mentioned, this isn't a question I can answer without considering the politics, a banned topic on the KSP forums. The same goes for a lot of real-world space exploration topics past and present.
  4. Yeah, these things vary depending on jurisdiction. Britain has a good one I feel with the two distinct intermediate signals. At pedestrian crossings you get flashing amber after red, which means you can go once any pedestrians have completely cleared the crossing. (Mind you, over here pedestrians can and will cross anywhere they like anyway) Likewise, whether it's legal to pass through an amber light will vary, and I admit to not knowing the law on this in Britain. But it's definitely bad driving to try and beat the amber light.
  5. A processor that is overclocked too high has a chance of making errors. If one of the calculations involved in something like designing a bridge or calculating a company's accounts gives a wrong value and nobody notices the consequences could be very serious indeed. That's why you don't see overclocking in professional settings.
  6. Tests in KSP show that yes, the recent Core i5's are much better than the old Athlon IIs and Phenom IIs when it comes to handling the big part count ships.
  7. https://en.wikipedia.org/wiki/Instructions_per_cycleIt's basically about the details of the processor's design that mean some processors do more, per core per megahertz, than others. Even though clock speeds dropped back after the end of the Pentium 4 and have only increased slowly since then, improvements in IPC have meant modern processors are much faster than old equally-clocked ones.
  8. Probably possible but not easy. Back in 0.90 FAR I did a Basic Jet spaceplane. FAR then gave the Basic Jet a similar top speed, but I was able to climb to a rather better 16 km on it before lighting the rockets. Whether it's *useful* is another matter mind you, it could easily have an inferior payload fraction and cost-per-kilo-to-LKO when compared to a good regular launcher.
  9. Well, what other choices were there when Harvester was starting out? A custom engine seems out of the question for a single guy with little or no game development experience doing this as a personal project on company time. Unreal Engine, so often suggested as what KSP should use, was at the time very expensive and from what I've looked into I think it's even less suited towards KSP than Unity. Similar cost issues applied to most commercial engines back in 2011, while Free engines are often weak on documentation, a big deal for a novice developer. SpaceEngine wasn't being licensed and still isn't and I'm not sure if it even has a physics model to speak of.A discussion on making a game like KSP in Unreal Engine: https://forums.unrealengine.com/showthread.php?29261-how-to-create-planet-size-world . It sounds like making KSP in UE would be extremely difficult if not impossible.
  10. The broken patcher is Squad's fault. GoG being slower in making 1.0.4 available might be down to them, Squad, or both. Keep in mind that how quickly an update or patch is available is only one of many things to consider when deciding where to buy your games from.

    Riddles

    An apple? An Apple?
  12. I think everyone would like to believe that. Unfortunately experience has shown it isn't true.The other factor I think is that Winx64 behaviour has been very variable. The original "hack" was OK, as was the first Squad release. A couple of versions later we had a Winx64 version that was flat-out broken with a bug preventing career progression (0.90 I think that was). Perhaps the new hack in 1.0 is greatly improved. Even on the same version it's often been a case of it works well for some players, is hopeless for other players, and nobody knows why.
  13. Yes. Yes. Yes. Yes. Run it from the command line using mono ckan.exe , the GUI will open. Virtually all. The only exception I've found is "Advanced Fly-By-Wire", a mod that adds controller configuration options, which has separate Windows and Linux versions. No. Linux 64-bit is stable and all mods I know of support it. Yes, with one caveat - if you set your Linux system in a language other than English you need to be careful with the "locale" KSP runs under. If you have an nVidia graphics card you will need the proprietary nVidia drivers to get good performance. If you have an AMD graphics card you may want the proprietary AMD drivers and can expect underperformance compared to on Windows whatever driver you use, though for KSP it might not matter. Either way you should install your graphics drivers, and most other programs, using Linux Mint's package manager or software centre. Don't download Linux software from websites like you would on Windows unless you've searched in the package manager and it's not there.

    Riddles

    I guess guessing. Or riddles.
  15. Those are two different things. In one material sound might not reduce much with distance, but nonetheless travel quite slowly. In another material it could travel fast but also die away in a short distance.In general v = √(K/ÃÂ) Where v is the speed of sound, K is the stiffness of the medium against being compressed, and àis the density. In a gas stiffness is proportional to pressure which in turn is proportional to density, so changing density changes stiffness and the effects cancel out. You can I hope intuitively see that a more stiff medium will transmit sound faster. If you shove one end of a medium that's stiff, you expect the whole thing to move nearly-rigidly and thus nearly-instantly. If you shove one end of a medium that's floppy you expect it to squash up near where you pushed. The transmission of that shove through the medium is a sound wave. It's less easy to see intuitively that increased density slows sound, but that is indeed the case. The reason solids transmit sound much faster than gases is then that the solids are more stiff while the gases are easily compressible. The higher density of solids actually has the opposite effect but in most solids it's not enough to undo the effect of the higher stiffness compared to gases.
  16. I feel silly for only just realising, you're codenaming these in alphabetical order aren't you

    Electromagnetism?
  18. http://forum.kerbalspaceprogram.com/threads/42877-CPU-Performance-Database The Pentium G3258 seems to underperform compared to the i7's and i5's despite matching it for clock. Perhaps the Pentium has less cache or something, or perhaps even though KSP only heavily loads one core it still helps to have four rather than two. In the wider spectrum of things though it's doing well. I expect yours despite the lower clock speed will beat out more expensive AMD processors as well as most pre-Sandy Bridge Intels. Keep in mind those tests start with a 600-part rocket after all.
  19. Yeah...the problem is that "such as" renders what follows pretty much meaningless, and leaves only what precedes. "Corporate transaction" is incredibly vague which is of course what Microsoft's lawyers want. They have all the power and you have none.
  20. You'll probably want at least one case fan. Looking it up I think that case does come with front and rear fans, but you could ask the seller if unsure.
  21. C:S is easily more graphically demanding. On the CPU side it depends. KSP is poorly multithreaded so shows up the weakness of CPUs with lower single-threaded performance like the AMD FX range. Cities: Skylines is excellently multithreaded so shows up the weakness of CPUs with lower overall performance including recent Intel dual-cores. Both games share that they can be very CPU-intensive, and that the CPU load depends on something the player controls - part count in KSP, population in Cities.
  22. The 750 comes in 1 GB and 2 GB variants, the 750 Ti I've only seen with 2 GB. I would avoid the 1 GB versions of the 750, it's not really enough for games nowadays. At the moment the pricing on the 2 GB 750 and 750 Ti is so close (at least in England) that unless you absolutely must keep to a budget or you've found a 750 at bargain price it's hard to justify not getting the 750 Ti.
  23. Graphics cards are massively parallel, with hundreds or even thousands of processing elements. nVidia calls them "CUDA cores", AMD call theirs "stream processors". The 750 Ti has 640 CUDA cores while the regular 750 has 512; in other respects the cards are basically the same. For a wider context, the bottom end 210 and 610 have 16 and 48 CUDA cores respectively, while the $1000 Titan X has 3072.
  24. Advice on what game settings affect CPU and GPU usage, http://www.gameplayinside.com/strategy/cities-skylines/cities-skylines-game-performance-review/C:S is a more demanding game than KSP though, so it could just be your computer.
