[02:12:03] #KSPOfficial: mode change '+v eriophora' by ChanServ!ChanServ@services.esper.net [06:10:40] hehe, i was watching a nonsequitur video, and at the and they mentioned louis rossmann and both kyle and aronra knew about him [08:47:57] who?

[14:50:34] (not KSP, happened at work) [14:50:47] I think that will be my favorite bug in a long time [15:19:45] Action: UmbralRaptor has not [15:20:29] Beresheet crash site! http://lroc.sese.asu.edu/posts/1101 [15:21:07] oof [18:24:08] i'm going to try to keep a research lab in solar orbit near kerbin [18:24:45] but i'm afraid of doing a rendezvous for crew rotation [18:25:25] encounters in solar orbit are a lot harder to make [18:25:52] indeed, and i need it to be a short(ish) trip [18:26:04] 20-30 days at most [18:26:24] we'll see [18:26:35] if only there were lagrange points? :) [18:26:42] If only. [18:26:44] in ksp 2 [18:27:09] in unreal engine [18:28:03] when unreal engine includes a mechanism to solve multidimensional differential equations? [18:28:14] I mean, you can exploit the current system to park a station just outside of Kerbin's SOI [18:28:41] but you know where the lagrange points are [18:28:47] so you could kind of simulate them [18:28:56] adding them artificially instead of really computing it [18:29:24] the same way in reality there is no hard limit for soi, bat that is also an approximation [18:29:24] Action: UmbralRaptor waves vaguely at Principia [18:29:32] yes that is the correct way [18:30:28] i've never really looked at the differential equations for multi body physics, or how expensive they would be computationally [18:31:23] they are not that bad. but you have to compute them for every time, instead of just running t in the solution as ksp does now [18:32:16] there's three layers of that going on, first layer is the planets/moons how they move, second layer is your vehicles how they move, and third layer is the prediction how your vehicle will move through maneuvers/patched conics/... [18:32:51] if you do a complete computation, these are all the same [18:33:52] but not all these results need to be available at the same time [18:34:32] you can neglect the vehicle's influence on the solar system [18:34:53] well, that's an obvious optimization :) [18:34:59] the big issue is the prediction. ksp now can predict infinitely [18:35:16] there is no difference between running your simulation loop and predicting [18:35:44] so you just have to take out the delays for predicting, but then you just fry the cpu for even a few years of prediction [18:35:55] the thing is, running the simulation might be too costly to provide meaningful feedback for the prediction [18:36:01] whixh needs to be redone every time you move anything [18:36:21] i guess that is why there is some limit in principia [18:36:31] but i havent ever used it, just saw it in a video [18:37:13] i've no real clue what pricipia even is [18:37:24] wasn't that the name for newtons book? [18:37:28] yes [18:37:29] nbody physics [18:37:36] that is why the mod is called the same way [18:37:39] it does the same [18:37:46] just runs the differential equations correctly [18:37:50] what the game doesnt do [18:42:19] what a meaningful prediction needs is that you precalculate and cache the movement of the planets, so you don't have to recalculate it for every change in your maneuver nodes [18:42:48] which is potentially a lot of memory, and might need tweaking to the maths [18:44:26] i dont actually know how it works. but it has to run the real equations. maybe not for every point, but for some and then interpolate, who knows [18:45:45] before i send up crew i need to send up an expansion, so i'll get to have a crewless try to find a short way to encounter it [19:17:17] http://www.spacedaily.com/reports/EXTREME_Crunch_Looming_if_No_Limits_Put_on_Space_Mining_Gold_Rush___Research_999.html [19:17:31] we havent done a single off the planet mining operation [19:19:51] it will happen this century, i'm sure [19:20:29] from the 2070s onward there'll be huge orbital refineries [19:39:23] and we need cheap gold and other metals for technical purposes [19:41:39] I bet we could make self replicating machines on Earth in 10 years. [19:44:26] and destroy the planet [19:44:40] potentially the whole solar system [19:48:29] well, I already turned the galaxy into paperclips once [19:55:29] Yeah, they might turn all terrestrial planets into space ships and habitats. [19:55:45] If we tell them to. [19:59:57] And they'll colonize the galaxy. [20:13:50] i hope so [20:14:13] i hope us or our creations will spread everywhere [20:14:23] make total destroy the whole galaxy [23:15:58] #KSPOfficial: mode change '+o UmbralRaptop' by ChanServ!ChanServ@services.esper.net
