[06:01:11] yes [06:01:40] (i haven't actually watched simpsons in like 5 years) [06:16:46] I used to keep track of all the episodes I'd seen [07:11:25] Where in the VAB is the TACLS Liquid O2 to O2 converter? In the R&D it's in Improved Power Generation and Storage. Can't find it in the electrics section and I've also used the search function. http://bksys.at/bernhard/temp/screenshot20.png [07:12:14] where on earth is carmen sandiago [07:38:04] oh boy [07:38:23] I'm here [07:38:54] so am I [08:04:59] hehe [09:18:46] hey [09:18:47] http://omega.e-sim.org/lan.87/ E-sim economy and battle game join your country and conquer the world. Server is new!!! Very simple and nice game just try if you want you pm me also you can suggest me any browser game you played with your referer o/ [09:23:47] no. [09:25:26] kbuck: guess one got through? [09:26:24] derp.. [09:28:09] they do from time to time [09:29:23] ... like anyone would fall for it.. [09:33:16] the ones that do are also the ones likely to enter their CC data on any random website [09:54:10] but why are they not using boring company flamethrowers https://www.bmeme.hu/memes/2019/01/8577_6i2wrq5j05_normal.jpg [10:05:59] probably because its boring ;) [10:06:33] oh wait [10:06:38] i didnt want to link this [10:06:46] ok, not bad but still [10:07:06] https://twitter.com/elonmusk/status/1088680182540464128 [10:07:06] <elonmusk> Testing metallic heat shield at 1100C (2000F) @SpaceX https://t.co/frP5eZ5a0z [10:24:02] Action: JVFoxy just spotted a report someone on the ISS accidentally dialed 911.. c.c [10:24:16] lol [10:24:22] no way to get there [10:25:44] in least it wasnt from your stash alt ;) [10:26:00] http://twiar.net/2019/01/09/an-astronaut-accidentally-dialed-911-from-the-international-space-station/ [10:26:05] i dont have a stash [10:26:21] yeah nobody has em [10:26:32] ok, dutch, probably they dont have 911, because that is american [10:26:34] so like... ISS has a proper phone sorta thing you can dial out from? [10:26:35] honestly dont have one also but negative is always hard to prve [10:27:05] also outside number prefix is typically 0 [10:27:11] who chose 9 for that [10:29:29] ugh actually now I that I remember, my foster family phone number had one digit then 911 and then three more numbers on it back before area code had to be included. Miss the first digit, it ignored everything else and went through as 911 [10:29:37] the existence of these prefixes is one of the reasons i prefer my phone over a landline even if i am in roaming [10:30:14] jv lol ouch wonder many people called 911 trying to call your foster family [10:30:22] hehe probably the routing rule was set to prefix instead of complete match [10:31:24] better a false call to 911 than a lost call to 911 due to someone pusing 1 too many times [10:31:27] actually, it only slipped twice... [10:31:31] (or some other fumble) [10:32:08] I was like 'crap sorry, stupid home phone number, missed a number... [10:34:12] any case.. I was trying to see what was going on with AO-85 and AO-95 recently. -85 jsut came out of slumber, in safe mode for the moment. (they worried battery may have been damage). I wanted to see any new changes to -95's radio status or if its just dead in space now [10:34:51] AO- are designations for armature ham satellites.. [10:35:07] amateur (ugh auto spell) [10:39:40] my dad called for an ambulance last night.. I think he used 112 [10:39:57] yes it is 112 in eu [10:40:01] hope he's ok? [10:40:47] or.. whoever [10:40:58] yeah, it was for him [10:41:30] he seemed a bit confused about which number to call [10:42:26] he said something like "what's the number for 911?" [10:42:48] hehe american culture spread through movies [10:43:25] well considering 911 could be just meaning EMS [10:44:14] the emergency number here in the UK is 999 (112 works as well), but I think he wanted the non-emergency number [10:44:49] its 0 for operator here in NA... same as over the pond or? [10:45:11] I wouldn't know these days either [11:37:51] eh, i was eating some cucumbers and the last one, when i took the first bite, sprinkled the monitor and the wall above it with fluids [11:38:33] probably there will be some permanent stains on the wall [11:42:09] at least the screen is now clean :) [11:44:28] eep, someone else has had to phone 999 [11:44:41] house fire not too far away from here [11:55:22] are you an incident magnet? [12:13:11] #KSPOfficial: mode change '+o APlayer' by ChanServ!ChanServ@services.esper.net [12:17:40] it is only 8°c outside but it feels warmer [12:18:47] good for you. it is around 0 here [12:19:18] it is 18°c in my room but it feels a lot colder [12:19:38] A few weeks ago, the weather report said -273 (° C) here [12:19:42] that is already getting cold for me [12:19:46] lol [12:19:50] Only for a day, thankfully [12:19:52] heh [12:20:22] how funny would it be if at least some point on earth it could get so cold that a component of air liquifies [12:20:41] "whoosh", the tornado said [12:20:41] that would create a low pressure that sucks in more air to liquify [12:21:20] there are probably some places on earth that are cold enough for dry ice to form [12:21:25] or at least, not evaporate [12:21:29] "whoosh", the wave of liquid oxygen said [12:21:56] dont you want to swim in the lakes of titan? [12:22:17] "Aaaaaa", the swimmer in a lake of molten titanium said [12:22:28] actually liquid methane [12:22:30] Action: APlayer stops [12:23:08] Well, you need to admit, liquid methane does not sound nearly as exciting as liquid titanium :P [12:23:25] but you cant swim in molten metals, too dense [12:23:47] So you would probably sink in liquid methane [12:24:00] (It's /you/ who is too dense!) [12:24:03] hehe [12:24:19] obviously, anybody who is trying to swim in a cryogenic liquid, cant be too smart :) [12:24:20] I heard taking a mercury bath is hard [12:24:52] For that matter, we are discussing a whole range of liquids that are hard to take baths in [12:26:28] OTOH, we don't know about the density of liquid methane under titan's atmospheric pressure. Is it significantly different from liquid methane at 1013 hPa? [12:26:48] liquids are uncompressable [12:26:58] That's an approximation :-) [12:27:19] well, they might be a a tiny bit, but doesnt really matter for density [12:27:45] at least somebody needs to build a kerbal and a sandcastle from the mud on the lake shores :) [12:28:22] A fish can only change depth because water is compressible which changes its density [12:29:37] unrelated. a fish can change its own density [12:30:05] But it maintains a specific depth by matching its density to that of the water at said depth [12:30:28] and it could do that even if densoty ws constant [12:30:48] for sinking it either swims down or changed densoty to sink, then readjust again to float [12:31:12] but yes, there must be a small densoty difference [12:31:38] just not too much. and as far as i remember titan has around earth level pressure, maybe a bit more [12:31:49] I suppose it worky without a density gradient, alright [12:31:54] works* [12:32:03] Fishy swimmy worky [12:32:35] unless it has some bladder problem. you can see that when it struggles to swim down or up [12:32:59] is the density difference from pressure bigger than the density difference from salt content? [12:33:28] 1.45 atm according to Wikipedia. [12:33:32] At Titan, that is [12:33:45] I had a number like 4 or 5 atm in mind [12:34:03] i know sweet water in oceans can cause problems, animals sink in it and stuff [12:34:59] so the answer is probably reverse [12:35:50] The bulk modulus of water is about 2.2 GPa.[40] The low compressibility of non-gases, and of water in particular, leads to their often being assumed as incompressible. The low compressibility of water means that even in the deep oceans at 4 km depth, where pressures are 40 MPa, there is only a 1.8% decrease in volume.[40] [12:36:12] Why do they quote the same source twice in a row? [12:36:24] for different data [12:36:43] there is a whole article for properties of water [12:36:57] what's a "bulk modulus"? [12:37:01] Wouldn't that require quoting once or quoting twice and more specifically (as in, where in the source paper the data is mentioned)? [12:37:02] i dont know [12:37:32] local leet time [12:38:15] http://hyperphysics.phy-astr.gsu.edu/hbase/permot3.html [12:40:57] supposedly hydrostatic lift works because of the pressure difference between the top and bottom. but what happens if you put a thin sheet of material completely horizontally in a liquid? [12:41:03] would that negate lift? [12:41:43] I suppose the thinner your sheet, the less mass it has [12:41:56] Because a = F/m, thickness cancels out [12:42:13] it still has densoty [12:42:19] i cant write that word lol [12:42:36] And width/length also cancels out, because more liquid is displaced the greater the area of your sheet is [12:43:27] I mean, thin sheet = less pressure difference (= less F), but also less mass (= less m) [12:43:44] but the formula is for density [12:43:48] so the mass wouldnt matter [12:43:54] yet it requires pressure difference [12:44:03] Density is mass per volume [12:44:20] Volume is constant (and if it is not, neither is mass) [12:44:55] yes thin sheet means less weight but it still means proportionally less lift too, so they should keep the ratio [12:45:25] So hydrostatic lift still applies to very thin sheets [12:45:34] https://youtu.be/e3jRZgqhqoU [12:45:35] YouTube - Brushless R/C ROCKET Vertical Landing Test #2 - RCTESTFLIGHT [12:45:45] Because the pressure gradient to mass ratio remains constant [12:45:49] but i guess if i imagine a single molecule of material, that would feel brownian motion more than lift [12:46:27] i don't think the concept of "density" works for single molecules [12:46:42] Volume does not work for single molecules [12:47:46] and even the thinnest metal sheets ever produced were like 3 layers of atoms thick [12:48:16] hah, carbon wins again, 1 atom thin :) [12:50:06] yeah, you can scrape off a single layer of carbon, but it doesn't quite work the same way with metal :p [12:50:06] "All of our materials are coated with 3 atoms of metal!!!" [12:50:50] how do you make a sheat that thin? [12:50:52] sheet [12:51:13] Why would you need a sheet of metal (or carbon, for that matter) that is only one (or two, or three) atoms thick? [12:51:26] graphene already has some uses [12:51:37] Nano-tech usually requires structures, not sheets [12:51:41] it has some properties that are useful [12:52:20] I mean, where would you maintain that? Take it into the open air and bam - a nanoparticle hits it and knocks off a few atoms [12:52:39] Or a few atoms corrode away [12:52:40] then dont put it in open air [12:53:08] So the only places where you use that are extremely controlled environments [12:53:34] all of our ICs would die if they were unprotected [12:53:41] so it doesnt matter all that much [12:54:35] and there is an article of graphene uses too [12:54:36] Action: APlayer glares at the 1995 Nokia cell phone [12:58:19] i found an article with 2 atoms thick superconducting lead [13:00:35] strange, i woudlnt have thought there are epitaxial graphene manufacturing processes. my bet was on cvd [13:01:12] there is already a graphene industry. go carbon go [13:18:33] i'm assuming those are 2 layers on top of some carrier medium, so not strictly a "sheet", that you could pick up and move around? [13:19:39] probably [13:20:48] Well, you could consider anything a carrier medium, unless you magnetically levitate your sheet or something [13:21:07] I mean, you need to fix it in place somehow [13:38:48] i mean something more like: "the force needed to detach it is less than the force that would break it apart" [13:50:02] Is that possible on such a scale? [14:01:26] #KSPOfficial: mode change '+o BPlayer' by ChanServ!ChanServ@services.esper.net [15:55:44] #KSPOfficial: mode change '+o APlayer' by ChanServ!ChanServ@services.esper.net [16:04:41] k [16:04:46] anyone on? [16:04:56] BecauseLogic, hi [16:05:02] yo [16:21:03] things I like about neodymium: storing it [16:21:16] things I hate about neodymium: handling it [16:22:59] That's what HandlerExceptions are for :P [16:25:24] ...did you know that the 1 euro cent coin has a steel core? [16:25:54] Copper would cost more than 1 ct if you used that much of it [16:26:09] All of the copper plated cent coins have steel cores, not just the 1 ct one [16:27:37] question [16:27:45] Answer [16:28:05] how should I account for constant acceleration of ion engines when doing an interplanetary mission [16:28:24] In what context? Account how? [16:28:45] lets say kerbin to duna [16:28:55] Stock ion engine, no mods? [16:29:00] correct [16:29:09] Account for it where? [16:29:20] lets say I want to intersect with Duna, but keep firing my engines [16:29:25] for the whole time [16:29:27] In KSP, the stock ion engine is powerful enough that you can do a Hohmann transfer [16:29:36] You don't need constant acceleration [16:29:39] nah, I don't want to do a hohmann transfer [16:29:54] Alright, so you want to be there as fast as possible [16:29:58] yep [16:30:17] In that case, prepare to run your game for a few weeks and check whether the burn is okay every few days :P [16:30:32] You probably want to calculate in what direction to burn, though? [16:30:50] well, yeah, since flight manuevers a basically useless here [16:31:09] 1D kinematics equations seem a bit simple too [16:31:46] There is a mod, I think it was called solar sail navigation or something, that allows you to calculate continous burn trajectories like that. Mind you that last thing I know it was for KSP 1.2 or so and I never got it to work even for that [16:31:59] hmm [16:32:09] I wonder what they used to calculate that... [16:32:15] The other option is writing a kOS, kRPC or external calculator [16:32:52] oh yeah, is there a mod that allows you to warp while accelerating? or is that to buggy? [16:32:57] You may perform a simplified simulation of your vessel using a Runge-Kutta Integrator, which is actually a thing I attempted and kind of made a while ago, in HTML [16:33:00] JS, that is [16:33:20] There were some mods for that, but they were rather buggy [16:33:25] figured [16:33:41] Same KSP 1.2 thing, and never got to make one actually [16:33:43] I can't even use mechjeb anymore [16:33:47] Never got one to work* [16:34:59] What I did was a Hohmann transfer with a vessel that burned so slowly that it spiralled around the planet a few times before ejecting, and as the burn took 20 h or so, I got a mod to work that would allow for physical time warp at x20 or so [16:35:40] ...what kind of vessel was it [16:35:51] In the end, KSP started being wildly inaccurate at any timewarp higher than x8, so I used that [16:36:54] Ah, that was a Kerbin-Duna ship, The Martian style. A few 100 tons of mass, and because of high efficiency mod engines, it needed so much electricity that I could only afford one weak engine on it [16:37:10] gotcha [16:38:54] So I ended up having to write a simplified simulation tool - I should still have it somewhere if it is helpful - that would plot the scenario in 2D. Eventually I intended to use it to calculate at what point in an orbit to start burning if the burn is constantly prograde [16:39:18] But I had some time issues and I never ended up finishing the project [16:39:39] That is, I have the simulation code, but no calculations that return actually useful numbers [16:41:14] It would be only mildly helpful in your case, as it only simulates a spiralling burn around a single body, assuming a SOI of infinite radius. That is, it would have to be modified to also account for the motion of two bodies around a sun, and the different SOIs your ship crosses [16:41:57] And overall, what you are trying to achieve is pretty complicated. [16:42:01] I know [16:54:05] #KSPOfficial: mode change '+o BPlayer' by ChanServ!ChanServ@services.esper.net [17:06:08] stellaris is great... names the first construction ship "Fabricator", the second "Fabricator" and the third "Fabricator II" [17:15:39] you have to 0 and no 1 [17:20:18] UmbralRaptor: yeah; I've bee slowly banning yet another ISP that they connect from [17:20:40] fun [17:23:39] it's because they're using a proxy service dedicated to ban evasion; it's actually marketed to spammers [17:24:01] normally I wouldn't ban like 3 ISPs to deal with idiots like this [17:27:03] Still the freenode spam? [17:27:23] Also o/ UmbralRaptor [17:28:10] Have you found anything on my problem after I left that day? I was sick for a few days after that, so I did not check in, and almost forgot about it [17:32:35] I haven't seen the freenode spam since december or earlier [17:37:00] Sorry, not remembering quite what the problem was at the moment. [17:38:08] How long an object takes from altitude a to altitude b given a starting vertical velocity v and accounting for the gravity gradient [17:39:44] If you have not, this is not a bump to get you to work on it, just asking if you figured something out back then while you were at it, if not, I am just going to start approximating things or use a numerical method [17:48:01] Ah, sorry, got distracted by other things >_>;; [17:48:43] Plugging equations into wolfram alpha gave messy results.

[20:28:24] Yeah I got the game right when it first got released and I'm running it on a Mac like a peasant i know [20:28:41] Sure how do I DO THA [20:29:19] The URL is the address you have at the top of your browser window.
