[00:03:32] #KSPOfficial: mode change '+o purpletarget|ktns' by ChanServ!ChanServ@services.esper.net [00:04:59] https://media.discordapp.net/attachments/186186669324500993/542133366028369952/51450679_1301867723289570_5778596927302008832_o-1.png?width=631&height=469 [00:37:02] I'm pretty new to game, are there any mods I should get to start or just do career mode vanilla first? [00:39:18] I like sandbox the most to be honest :P [00:39:50] I don't think you really need mods when starting out, but if you want more parts/features/things then you should look into it [01:04:30] I tend to shill science mode as newbie friendly, but it's ultimately your call. [01:05:34] And yeah, with 1.6, I'd say that one of the most common reasons to get a mod (”V calculations) is mostly practical in stock. [01:40:03] huh... so doing some figures here for alittle jet plane.. [01:40:49] learjet is 15,000lbs takeoff, 2 engines run 13.1kn each.. [01:42:30] my plane is 21,000lbs, 2 engines running at 18.5kn, but flying around 10km up, nearly 550m/s.... figures are somewhat close, though aren't kerbal stuff suppose to be smaller than the real thing? [01:47:50] I suspect differences in engine performance + some aerodynamic fudging + learjetsactually have stability issues above ~mach 0,82? [01:49:32] lol.. mean while I'm doing nearly 1.7mach... 1/2 hour flight to the poles, I'm already on descent to the ice sheet and still have 554 of 700 fuel remaining... [01:51:07] earlier was testing flying at under 2km alt... was only doing about 320m/s burning rate of 0.12.. at 10km up, I'm doing nearly 600m/s, only burning between 0.10 - 0.08 hmm... [01:51:27] sorry.. I was down 1/4 throttle while under 2km... [01:54:52] Yeah, stock KSP jet engines allow for supercruise. Check out the thrust curves in the config files >_> [01:58:32] ya but... with a pair of wheezlies? [01:59:45] even a pair of juno's do pretty decent despite what the flavor texts says. Acceleration isn't great but does get some respectable speed [01:59:54] Thrust does something like a slow falloff up to mach 1,but then increases with the actual peak at like 1,3 or 1.5 [02:00:37] ya I know.. some function of speed and alt.. [02:01:06] wheezlies do pretty good at low alt but suck fuel badly, overheats if kept too high powered [02:01:32] I'm not sure what engines they're actually emulating [02:01:52] I've a little f-zero type thing I made, 3 of the engines on the back. crazy fast at low alts but ugh.. engines heat stupid fast [02:03:54] did a wanna-be-f18 jet... good speed, just gotta careful on pitch, wants to pull stupid high g's and rip itself apart [02:07:10] Hah [02:08:07] Action: UmbralRaptop is always amused at how easy it is to build a thermally limited craft around the turboram or the RAPIER. [02:08:45] I love this plane quite a bit, I ported it over from an older version KSP career. Cheetah 100: https://imgur.com/a/QroKfGv [02:09:15] 200 adds another mk1 cabin.. since the performance is so good. [02:13:01] oh... also adds extra strakes.. looks a whole lot longer...hmm [02:15:48] lol.. huh ok, fully fueled, seems aero is pretty close to cg, seems to fly ok though. [02:16:34] yay [02:18:12] trouble is... having aero that close, things kind of wanna pitch really hard. [02:18:35] just means being delicate on the stick when taking off... shrug [02:19:46] but ya.. anyways.. 200 here: https://imgur.com/a/dtsqoeU [02:20:02] and with that.. have to go soon. just waiting for traffic to calm down [05:57:45] Does anyone know what integration method KSP uses for physics? (implicit euler, runge-kutta, etc)? [06:02:26] depends [06:03:13] thermal is RK, rigid body is probably euler, orbital is black magic [06:04:38] (whatever RB uses for non-gravitational forces, cleaver tricks with Keplerian mechanics for gravitational) [06:04:40] are orbits still done with conic sections? [06:05:07] yes, still single-body [06:05:24] if you want N-body, use pricipia [06:05:43] er, principia [06:05:44] does the game even use integration with real time simulations [06:06:00] if it didn't, it would not work [06:06:04] at all [06:06:06] well I mean [06:06:56] you can kind of simulate movement of objects without integrating (much) [06:07:08] no, you cannot [06:08:39] I guess technically that's true [06:09:41] you cant, even if you do it without it, you had to do it before to get the solutoin [06:10:05] also, you're still integrating the parameters you feed to the solution [06:10:26] yeah, I kind of tend to forcet that the basic kinematic equations are essentially integration already [06:10:50] even if that integration is simply integral(dt) [06:10:58] like if you know the force on a body of mass m and you need to calculate its position and velocity after dt time has passed [06:11:36] but the question is, do you really need any specific integration method for that? [06:12:10] you're really asking the wrong questions [06:12:20] maybe [06:14:00] better might be: how much is analytical and how much is iterative, and what what iterative methods are used [06:14:13] that sounds better, yes [06:15:21] and that, I answered as best I can above :) [06:16:53] (I don't know what exactly physx uses for rigid-body, but it is not suitable for inverse-square fields, thus the mix of rigid-body (physx) and analytical (Keplerian) for off-rails orbits) [06:17:13] on-rails is pure Keplerian [09:06:12] I kinda want to play planet side 2 [09:58:38] why does garbage collection run so frequently n the VAB? [09:58:48] in-flight there is no issue at all [09:58:53] VAB is terrible [09:59:27] GC runs per second, lags editing [10:00:18] with memgraph addon I need to add 6GB heap padding to stop it (or make it much more infrequent) [10:00:39] that's a lot of garbage! [10:01:46] I do not use too many mods [10:02:32] kerbalism and scansat may cause something, but why in the VAB, when time is frozen? [10:08:04] #KSPOfficial: mode change '+o Deddly' by ChanServ!ChanServ@services.esper.net [10:32:08] Uh, there was an all electric garbage truck in my street today [10:32:10] woah [10:32:12] so quiet! [10:32:50] kubi: that's because Unity and C# are the wrong choice for such a huge thing like KSP ;P [10:40:21] can be [10:40:37] but why the VAB? [10:40:43] c# is fine its unity I think [10:40:55] only the mission browser it more simple than that [10:42:35] when ksp started off it was simple enogh that unity would be fine [10:42:40] it just grew a lot [10:43:22] it'd be better with C with some barebones ASM in C for optimization of certain functions. [10:44:05] true [10:44:28] but codin in C and assembly requires more consideration [10:44:38] e.g., proper memory management :) [10:45:25] and what "proper" is, shall be discussed over and over as the game evolves [10:59:58] the guy with the laser cutter isnt answering [11:02:10] kubi: yeah harder to debug [11:02:28] nowdays with internet people now just relase and patch later [11:02:54] old days you release and you better have done right job or you has lots angry customers with cardiage with bug on it [11:34:12] heh.. old days, back when things were on carts... on the flip side, stuff was a lot smaller then, easier to sift through the code [11:35:11] indeed [11:38:32] recall someone did a video on KSP... something about a deficit when it comes to working on coding and deadlines. [11:41:32] ah.. shadowzone... each version that comes out, programmers aren't given enough time to fix the bugs that keep adding up. Some cases, time is even cut shorter because higher-ups figure 'oh you have experience, you can do twice as much work now'... :\ [11:44:02] jeez [11:44:07] programming isnt production [11:44:15] yet they seem to think so [11:44:22] sometimes 10 line code is long and hard, and sometimes 1000 is easy [11:44:25] in a way it is [11:45:44] granted, 1000 line easy isnt very common lol [11:46:58] way I look at it.. we aren't machines, going to make mistakes, not exactly predictible.. [11:51:47] machines are not perfect [11:53:05] no... just needs a human operator to mess things up. Machines do exactly what they are told, nothing more, nothing less...

I've played 7 Days to Die today and exactly on the 7th night the garbage collector went crazy with all the zombies spawning and despawning. [21:13:01] Stuttering all the time... [21:16:52] hehe [21:16:54] did it die?
