  1. Hello so I am having trouble and I suspect it might be FAR. In simple terms the issue is that my ship is not slowing down enough on re-entry and after reaching about 5 km altitude my ship starts accelerating instead of decelerating even though it is already flying at supersonic speeds. Now fluid mechanics/aerodynamics is not something I am well versed in so I might be missing something but as fas as I know this is not how it should happen. Below is an album showing the problem, it is a sequence of images showing how the velocity does not slow down enough and how it starts accelerating after about 5 km. I apologize for the large amount of images I did not want to leave any information out that might have been pertinent to someone trying to help. I'm pretty sure we can discard the main suspect of too steep of a re-entry since as you can see in the first few images of the album the re-entry orbit is (ap,pe)= 74, 60 km which is not steep as far as I know. Also I don't think a steep entry angle would cause acceleration above supersonic velocities at low altitudes. I do have quite a few mods installed, and even though I am not a modder I can't think of any 2 conflicting to cause this particular problem. I do have the latest version of KSP (1.0.5) and FAR (0.15.5.4) in case anybody is wondering, and I can provide the versions for any/all of the mods installed. The list of mods that I have installed are: Adjustable Landing Gear, Asteroid Day, B9 Procedural Wings only, Buffalo, Dangit, DMagic Orbital Science, FAR, Habitat Pack, HullCam, Infernal Robotics, KAS, KAX, Alarm clock, Kerbonov, KIS, kOS, KW Rocketry, LaserDist, MechJeb, MRS, OSE workshop, Planetary Base system, RasterProp, Realchute, Remotetech, ScanSat, TAC LS, Taurus HCV, TweakScale, Universal Storage. I apologize if I am missing something dumb or if this is not the correct protocol of asking for help I do not mean to waste anybody's time. Also I completely understand that people might be busy with holidays stuff so don't worry and take your time. Merry Christmas everyone, and thanks in advance.
  2. Hello everyone, I am looking to buy a new all purpose laptop. I know laptops are not ideal to play games but other aspects of my life require that I have one. Probably the most demanding process I run at the moment is KSP which is why I ask here for help. For portability, screen size, performance, and other reasons I have landed to 2 final options: 1. Dell XPS 15 9550: CPU: Intel Core i7-6700HQ (Quad Core 2.6GHz, 3.5 GHz Turbo, 6MB, 45W) GPU: NVIDIA GeForce GTX 960M with 2GB GDDR5 2. Dell Inspiron 5510: CPU: Option A: Intel Core Xeon E3-1505M v5 (Quad Core 2.80GHz, 3.70GHz Turbo, 8MB 45W) Option B: Intel Core i7-6820HQ (Quad Core 2.70GHz, 3.60GHz Turbo, 8MB 45W) GPU: Nvidia Quadro M1000M w/2GB GDDR5 The Inspiron has the option of 3 different processors the other is an i3 thought which I will probably not pick. Both will have the same amount of memory (16 GB) and the rest of the specs seem to be irrelevant for this comparison (but I may be wrong and could look them up and add them if requested). I think I understand the main differences here one has better CPU (Inspiron) the other better GPU (XPS) what I don't know is how this relates to running different processes (in particular KSP). I've also heard that cpu, not gpu, is usually the limiting factor in KSP but it seems like when comparing computers each case is different and maybe a 0.2GHz difference is not that important considering the difference in gpu and/or price (I really don't have an appreciation of what 0.2GHz mean in terms of what it feels like to run a certain application). I guess the main question is in this particular case which one of these would you guys recommend?. Links in case anyone wants to check out extra information (some of the links may point towards different configurations of the model, but the specs above are the best for each, and probably what I would go for): Dell XPS 15 9550: http://www.dell.com/ca/p/xps-15-9550-laptop/pd?oc=nxps15550_bt_h1630pe&model_id=xps-15-9550-laptop Dell Inspiron 5510: http://www.dell.com/ca/business/p/precision-m5510-workstation/pd?oc=xctop551015usca intel.com Xeon Processor: http://ark.intel.com/products/89608/Intel-Xeon-Processor-E3-1505M-v5-8M-Cache-2_80-GHz intel.com i7-6700HQ processor: http://ark.intel.com/products/88967/Intel-Core-i7-6700HQ-Processor-6M-Cache-up-to-3_50-GHz
  3. So quick question how does the greenhouse work? Does it actualy produce food an oxygen and take some other materials or how does it work? I can't find any information on it and I can't find a way to activate it in game or anything. I probably missed something simple just can't figure out what it is.
  4. No I am not saying just sitting and waiting without launching anything. Right now Kessler syndrome is not so dangerous that we can't keep launching. if we start taking care of our satellites right now (i.e. follow the rule I talked about before) then Kessler syndrome will never become a huge problem.
  5. Kessler Syndrome solves itself over time. If we follow simple common sense rules and just wait then everything should be fine. The simple rule to is making sure that the satellites we launch are either taken to a graveyard orbit or made to burn up on reentry after their mission is over. It is farily simple yet it takes some money to use a bit of fuel to make sure the orbit decays. In the end that money might be saved because we won't have to spend it in shielding or on a mission designed just to capture debris.
  6. correct but the universe will probably reach maximum entropy killing all life on it before any significant fluctuation takes place. But yes. Awesome ted talk on this topic I recommend to everyone:
  7. So it looks like you guys could use this: http://trs-new.jpl.nasa.gov/dspace/bitstream/2014/20238/1/98-1132.pdf guy at nasa has thought about this. I think my favorite is the Bussard Ramjet although haven't really thought about it a lot or search about it so don't know if it is the best one. Solar sails might be useful. The problem is that realistic interstellar ships get insanely huge very quickly. Also if we find out we have 100 years we might want to trow a bunch of money at AI research and see if it can help us.
  8. Well my grain of salt is that time is an emergent phenomena like temperature. We can argue whether temperature is real or not and temperature is definitely not real when talking about the microstate you can't ask what is the temperature of that atom that wouldn't make sense, only when you have a large system and are discussing the properties of the macrostate then temperature becomes a very useful characteristic of the system. Time to me seems to be kind of similar, an emergent phenomena, but in reality what we perceive as time just comes from the fact that entropy is increasing. In a universe in equilibrium like the one you are describing there is no time since you have reached maximum entropy. Now in a regular system in equilibrium there is still some fluctuations that could lead to bubbles with lower entropy but I am not sure how those would translate to the universe you describe since things are too far away from each other to interact.
  9. I was thinking of the possibilities of having a part (like an arm or something) that does what a kerbal would of grabbing and attaching parts and connecting pipes and stuff like that. I think it would be great as it would add a new dimension to the mod. This would allow, for example, base construction before the kerbals get there and having a fully robotic fueling base. Probably someone has already thought of this but I couldn't find any mention of it.
  10. I thought that RemoteTech and Mechjeb had problems when installed together is this mod compatible with both at the same time or separately.
