[00:10:17] well yeah, terminology is near impossible to change [00:10:21] I see this in the nuclear industry [00:10:44] once people start using it its almost impossible to make them stop [00:14:56] #KSPOfficial: mode change '+o purpletarget_zzz' by ChanServ!ChanServ@services.esper.net [01:11:42] Action: UmbralRaptor stares at the Kerbal Chronicles. [01:12:11] Action: UmbralRaptor ðŸ”ª whoever wrote "rye" when they meant "wry" [01:16:41] I see it with literature. "Post-modern" etc [01:18:32] There were some other things, so I'm going to go with bad copy editing. [01:21:40] Anyway, it's a PDF on kerbalspaceprogram.com for some reason. [01:24:57] Electron had to overcome lotsa hurdles for their rocket...I did try a 0.625 meter launcher in KSP, and the think is REALLY unstable even with fins. [01:25:23] uh [01:28:34] Anyway, the PDF is a neat idea, but the execution hurts. :( [02:10:51] fellow rocket nerds, I ask your help in a mathematical sanity check. I'm running some numbers backwards and things aren't working out as I expect [02:11:57] rocket with final mass of 3 tonnes; target dv of 7.5km/s; burn time of 96 seconds; engine efficiency 350 seconds [02:12:53] with this information, calculate (1) rocket inital mass, (2) acceleration, velocity, and displacement functions of time for the burn [02:13:30] mass is the easy part; I get about 6.853 tonnes [02:14:23] (intermediary steps engine thrust 128kN) [02:15:06] Can we assume the burn rate is constant? [02:15:12] and the thrust? [02:15:26] yup [02:16:02] well then Mass(time) is linear. So, acceleration(time) is linear as force is constant. [02:16:15] then integrate [02:16:53] the acceleration curve I compute at approximately a(t) = 23.2222t + 19.4444; making v(t) = 23.222/2t^2 + 19.444t, yes? but solving v(96) does not equal the target tv I started with [02:17:11] you forgot the +c [02:17:24] v(0) = 0? [02:17:44] s/tv/dv/ [02:17:52] Clearly it isn't if you don't get the target delta-v you started with. [02:18:11] or maybe it is. [02:18:44] How'd you get thrust? [02:18:53] I'm assuming this is in a relative reference frame, fo v(0) (and d(0)) should be 0 [02:19:21] from Isp, I calculated Ve at ~3418m/s [02:19:37] well if we're just looking at delta v [02:19:55] assuming constant fuel consumption, that's 37.323kg/s [02:20:14] Ve * fuel rate should equal force of thrust, yes? [02:20:27] 350x9.8 = 3430 [02:20:28] thus, ~128kN [02:20:43] my unit of gravity is slightly different. (yay, game intervals) [02:20:55] g0' := 9.765625 [02:21:30] but close enough for government work. my v(t) function is of by over a factor of 2 [02:21:34] *off [02:21:35] that's still 9.8 to 2sf [02:21:54] 2sf? [02:22:21] all the initial figures are to 2 significant figures at maximum [02:22:30] ah. agreed [02:22:34] whatever, it probably doesn't matter [02:23:42] exhaust velocity times mass flow rate is thrust, that bit's correct [02:24:38] Did you make an error in solving for initial mass? [02:25:38] I don't *think* so... 7500m/s = (3418s) m0/3000 m0 -> 7500*3000/3418? [02:26:22] -> 6582kg [02:26:27] dV = Ve*ln(m_w/m_d) => dV/Ve = ln(m_w/m_d) => e^(dV/Ve) = m_w/m_d => m_d*e^(dV/Ve) = m_w [02:26:37] ah! ln [02:27:00] I thought it seemed really low [02:27:14] => 3*e^(7500/3430) = m_w [02:27:40] 26.714... tonnes? [02:28:11] For 7.5 km/s delta-v, sure. [02:28:27] that's probably it, then [02:28:29] and yeah 3 is in tonnes, and 7500 and 3430 are in m/s [02:29:15] I'll re-run the numbers with that fixed inital mass. thanks! [02:29:38] 350s Isp, yeah that's reasonable [02:30:31] approx 10% payload [02:31:05] yup. I was very askance of the about 30%, but didn't make the connection to re-check my rocket equation [02:31:17] er, 40% [02:31:19] also forgot to remind you that Isp->Ve uses 'standard gravity' and is independent of what gravity actually is. [02:31:34] ah. good catch [02:31:57] KwirkyJ! [02:32:09] UmbralRaptor! *POMF* [02:32:51] ouf [02:35:41] Anyway, I did some shenanigans for analytic solutions to the scrollback at one point. https://drive.google.com/file/d/0Bxef3KjILrVraldBdGJkY3EwdUU/view?usp=drivesdk [02:41:27] dv = 7500m/s; v0, d0 = 0; m1 = 3000kg; Isp = 350s [02:41:46] Isp*g0 = Ve 3432m/s [02:42:07] with rocket equation, m0 = 26680kg [02:42:30] fuel mass = 23680kg [02:42:56] fuel rate (burn 96 seconds) = ~278kg/s [02:43:34] correction: fuel rate = 246.666kg/s [02:44:38] ~850kN? [02:44:45] fuel rate * Ve = thrust = 848kN [02:44:50] @.@ [02:46:03] a0 = ~32m/s^2, a1 = ~283m/s^2 [02:46:05] You okay there, JCB? [02:46:43] That's some kind of acceleration right there. Almost like a rocket. [02:46:52] a(t) = 252t + 32 [02:47:04] er, 251t [02:47:16] eh... depends. headache+forgot was on here still+trying to catch up on things.... [02:48:32] v(t) = 251/2t^2 + 32t + v0 ? [02:49:11] Designing something like Sprint missile? [02:49:20] kinda, yeah [02:50:10] but v(96) = ...1 159 680 m/s? != 7500 [02:50:20] m(t) = m0-A*t [02:50:44] not sure that's displaying properly for me [02:50:45] a(t) = F/(m0-A*t) [02:50:54] it's m-dot [02:51:01] ^ [02:52:01] ? [02:52:06] 283m/s/s is correct for the dry mass acceleration [02:52:09] Assuming constant thrust, acceleration is more like 1/x than x. [02:52:27] m-dot, mass flow rate [02:52:36] mm [02:52:38] KwirkyJ: m-dot as in a slightly silly way of writing dm/dt [02:54:23] so my initial acceleration is way off? [02:54:36] or, the nature of the acceleration curve? [02:55:11] The nature of the curve. [02:56:23] a = F/m. since m varies constantly with time, it might as well be F * 1/t [02:56:45] yup. just convinced myself of that [02:56:56] (cor, tha's dense) [03:00:01] a(t) = 848/(26680-247t) in this case? 848kN thrust, 26680 m0, 247kg/s m-dot [03:02:57] looks alright [03:09:57] v(t) would then be its integral... v(t) = -848/247 log(26680-247t)? [03:12:21] (+c) [03:14:47] #KSPOfficial: mode change '+o Dman979' by ChanServ!ChanServ@services.esper.net [03:16:59] ah, 848 is 848000 [03:17:27] c -> 34.99... call it 35 [03:18:05] v(96) then becomes 7550m/s; very near the dv expected [03:18:38] thank you both for your input [03:21:35] yay [04:43:37] hmm.. factorio.. you can power the train by rocket fuel... eh.. [04:44:04] makes it go 180% as fast... hmm.. [04:45:55] "We forgot to put an endcap on that belt... yes, there is solid fuel leaking everywhere" [04:48:23] huh.. wheres that come from? [04:49:16] my brain, mixing the belts in factorio (which don't spill, for good gameplay reasons) and a throwback to the ;mission generator, with a "There is solid fuel leaking everywhere!" outcome [04:50:47] with solid fuel being both in factorio and KSP, serving roughly different purposes [04:56:13] ah ya.. the guys were using solid fuel to run the train and tanks [04:56:40] I was watching Guude and his friends playing over on youtube... [04:57:17] Solid fuel is (or, was) more efficient in terms of inputs [04:59:02] can't turn it off though...

It's one of those things that require distinct answer to which gender the user would be [09:32:14] you could solve this with an adapter ;P [09:33:01] I wonder what happens to the hard parts, since there's a sieve [09:33:15] but I'm not sure if this is inappropriate for this channel [09:33:57] Mat2ch, noone would design an addition to a complex working device for political correctness sake [09:40:00] Mat2ch, looks like it just has one-use pack in it where solid parts are kept [09:40:12] Ah [09:40:17] also those ARE adapters [09:40:23] that's possible [09:41:31] http://ic.pics.livejournal.com/lozga/3516068/288778/288778_original.jpg [09:54:59] aieee haven't played in a long time and I'm trying to figure out a minimum of mods to use, I think I'm already going overboard [09:58:24] the sky isn't even the limit when it comes to KSP mods [09:58:37] only your RAM/CPU/GPU is the limit [13:06:37] GlassFragments: https://i.imgur.com/fLGveJVr.jpg [13:06:50] Hope nobody is taking Inokashira home [13:07:52] ...inokashira? that't wont get you back to kita-senju [13:09:53] TheKosmonaut, school ended super early today so that there would be enough time for those living further away to get home [13:10:19] GlassFragments: no. I saw this posted [13:10:35] GlassFragments: Tokyo gets so chaotic in the snow [13:10:41] Is this your first snow here? [13:10:50] my first real snow [13:10:51] The grocery near my house is abandoned [13:11:10] It's great. Because they put everything on discount by 7pm. [13:11:36] It's the heaviest in a while. [13:11:49] in 2015/16 it snowed while I was sick in bed and somehow one week later I could still see a pile of snow next to a road somewhere [13:11:53] My neighbors are shoveling already. Why bother when it's still falling at a good rate. [13:12:16] It's like going outside and hosing the sidewalk when it's raining [13:12:28] yeah I can hear shoveling all the time [13:12:37] ve2dmn: it was the "Extreme Textures" :) [13:14:10] TheKosmonaut, sucks that my phone battery ran out when I got to my station because ekimae was fairy tale level beautiful [13:14:56] also my cracked screen started falling off so I had to be careful not to get the exposed circuitry wet [13:17:36] TheKosmonaut, apparently some lines have already been closed off for strategic purposes https://twitter.com/878ne/status/955335690308349952 [13:17:36] <878ne> ºé¤Êü¢’M~ZkS“j“M“g‹eeeªï¿eee https://t.co/7SfytZrfjs [13:22:28] I hate that train [13:23:40] if you hate the people movers, there's more: yurikamome being driven manually https://twitter.com/taka1974/status/955351460631388160 [13:23:40] †ŠK‚KÕKâ https://t.co/GnVcwiGVZz [13:25:16] Huh never seen that one before [13:27:39] the box with the controls is clearly visible, I think there might even be a sign that you might have to give up your seat if they have to operate manually [13:28:22] and I think I linked this before but here's proof that monorails are superior to people movers https://twitter.com/jza80supraakb48/status/955219803148492800 [13:28:22] j“KØDf‹hc_‰âÎìüëLéÃ»ëÕØk() https://t.co/wIh1TR6OTc [13:28:27] Yeah I know that. I just haven't seen it operated before [13:29:34] I also had a JR east driver signal me to stop filming out of the front window [13:35:56] zilti: ... I rest my case :P [14:44:42] Good morning [14:46:39] Ahaha. Because of the gov shutdown Falcon Heavy can't be operated [14:46:48] the universe doesn't want SpaceX to fly :D [14:47:16] Action: ve2dmn facepalm [14:47:24] The art of compromise is dead [14:52:23] I really wish we would learn form the lessons of the past. The generation that lived through the great depression were really risk-averse, but it served them well by building on solid founcation... While the generation that followed live through great wars and were willing to compromise to make stuff happen. [14:53:00] Not sure what our generation will be remembered for. [14:54:24] Dank memes [14:54:34] And the internet in general [14:55:05] Though you could argue that it's a multigenerational creation [14:55:35] TheKosmonaut: the historian of the future will have a lot of crap to look at to find the good stuff [14:56:30] but then again, the previous generation didn't have the means to publish, so there's probably good material that died in the past, forgotten to the ages [14:57:01] There's plenty of utter garbage from the past too. It just doesn't quite stand the test of time. [14:57:30] Hopefully, SpaceX keeps their Texas launch facility construction at a good pace [14:57:34] Like that steam-powered door from ancien greece that was just 'a curiousity' and didn't manage to caught on [14:57:36] ~2019 ish [14:58:16] ve2dmn: there was a Roman site in todays Turkey (iirc) which used a waterwheel for driving a saw [14:58:42] the first invention of a steam machine was used to turn an ox over the fire... [14:58:58] Mat2ch: I guess the time wasn't right for the idea to flourish into more [14:59:06] (well, the first documented steam machine at least) [14:59:13] ve2dmn: slaves were cheap. [14:59:59] Mat2ch: Typical. Blame the economy :P [15:00:48] (The Economy, or the fight for ressources, explains a LOT of things) [15:01:39] Like the greatest mathematicians were only able to do their thing because they were financed by rich and influancial people [15:07:09] Taking a page from math, I feel like the ancien one were more concern about the look of the function, while the recent generation are more obsessed with the first derivative and the second derivative of that function... [15:08:21] Sure Y=X-(10^10) has a positive outlook, but that means starting in ungodly debts [15:14:11] There's still a bit of a slowdown during the first 2 minutes after launch, but I can live with that. [15:14:33] Now all I'm stuck with is that, in space, the camera isn't centered on my probe, but instead on an imaginary point [15:15:02] zilti: try re-aiming camera? [15:15:58] ve2dmn: That doesn't work... [15:16:10] what's the key again... 'v' was it ? [15:25:55] did a white tiger ever look at any of you like you were food? [15:26:10] because it's like the scariest thing ever [15:26:53] Fluburtur: ...well, I mean, you *are* edible, so... [15:27:05] true [15:27:21] but being 3 meters above the kitten and protected by a strong window didn't do much [15:27:22] But, no, that didn't happen to me. How did you get the honour? ^^ [15:27:46] also there was a girl like 5 years old running across the window and the tiger was following her [15:27:52] Heh [15:28:14] and honestly, im often like "I want to pet big kitten" but this always remind me that those things are powerful [15:28:19] and that I still want to pet them [15:29:07] Fluburtur: If that happens in the wild, you must use the power of the 'red dot' [15:31:13] as in the band? [15:31:21] oh no I can't read [15:31:23] uh [15:31:33] ok always keep a laser pointer with me then [15:31:39] Always [15:32:39] I need to go back there [15:32:47] it's like a big park with only felines [15:33:01] and big enclosures too so they are pretty happy [15:33:13] Howdy [15:33:49] yo [15:33:59] you are just the person I need [15:34:36] Fluburtur: what's up? [15:34:50] Writing "Betchya woulda forgot that one." in technical documentation is not a good idea, even if I understood the meaning [15:35:28] https://imgur.com/a/hI0Uo [15:36:14] I was talking with a friend and we decided to make a rocket poweres me 163 [15:36:54] Oooh, nice. [15:38:32] Fluburtur: what's the uh...pole thing for? [15:40:35] it is meant to go in a me 163 [15:40:43] and the back is too small for a rocket [15:40:50] http://www.fiddlersgreen.net/aircraft/Messerschmitt-Me163/IMAGES/ME-163-Rocket.jpg [15:42:46] Oooh, so that's the exhaust pipe? [15:42:49] yeah [15:43:49] Random wifi network [15:43:51] Anyway [15:44:09] https://i.imgur.com/xOuLQtk.jpg [15:44:49] Cool! [15:45:09] What will you use to build the case? [15:45:15] of the engine? [15:45:42] probably aluminium [15:46:04] the casing of the fuel chamber itself isn't too critical but the exhaust pipe and nozzle will be [15:46:27] but it will use parafin and nitrous oxide so I gues it won't gt too hot [15:49:06] Interesting, a non-rocket candy fuel [15:49:36] don't worry I will build candy ones too [15:50:18] Fluburtur: using aluminum could be a little dangerous though. You could turn your engine into an frag grenade, should there be am explosion [15:50:42] that's what testing is for [15:51:45] True [15:52:26] Have you calculated the thrust and burn time yet? [15:52:48] no [15:52:51] I have done no math [15:53:00] and this model is just there to look nice [16:13:01] I wonder what our universe would look like with 'c = something else' [16:13:24] Or if you changed the mass of the proton to be 0.0000000001% lighter [16:13:46] it would probably look like nothing because that would be impossible :O [16:14:11] Or course it's impossible. It's just a though experiement [16:14:58] I also wonder if these universal contants are real contants or if they are changing, but looks constant 'to us' [16:15:53] #KSPOfficial: mode change '+o APlayer' by ChanServ!ChanServ@services.esper.net [16:16:28] "come look at my computer, the intranet won't load" [16:16:35] "watch you'll walk into my office and it'll just work" [16:16:36] yup. [16:16:41] madmerlyn: it's much more interesting to think about then trying to debug a Java App that is basically a blackbox to me [16:17:01] downloadmoreram dotcom should fix your java problem [16:17:16] I download more ram all the time [16:18:32] madmerlyn: I'd appreciate if you could upload and mail me some of your RAM, I could use some more [16:18:48] so just saw a new custom kerbal controller build on reddit with a good ible on it too, I really need to get off my butt and do that [16:18:50] Also, please charge my internet connection, it seems to be running low [16:19:08] I bet there's a site to download more internet too [16:20:10] Well, Kerbals do it by slapping MOAR routers onto the rocket [16:21:45] Imagine doing a google search from space at a few minutes speed of light delay, though [16:22:11] you know what would be cool, if you could disable most of the HUD elements of the UI and have instrumentation on a custom controller on your desk instead [16:22:38] have your altitude counters, fuel gauges, etc. all on a panel and not on the screen [16:23:09] F2 does the first half of your request [16:23:20] except F2 disables a lot of stuff doesn't it [16:23:37] like can you adjust throttle during screenshot mode? [16:23:43] It disables all but the main image [16:23:53] I think you still have control, though [16:23:55] BadInternetCo do you know how to calculatenozzles? [16:24:21] ideally I'd like to just disable specific UI elements [16:24:42] alternatively I could do a KSRPC app with a flask server or something and have my instrumentation on a second monitor, but that would be less neat [16:26:10] madmerlyn: Telemachus?

I researched this a while back [16:29:18] he's working on a rebuild from scratch called Houston [16:32:02] static fire when? [16:34:11] Last I saw it was delayed without replacement date [16:34:42] Apparently the spaceport Rocket Labs built at Mahia is the first commercial spaceport in the souther hemisphere [16:35:03] and it has a latitude of 39 degrees S [16:36:02] Straya has 1 spaceport, and 2 retired spaceports, but all were military/govt. facilities, not commercial [16:36:11] Althego: fire is never static. Is is always moving [16:36:27] but the rocket doesnt, hence it is static [16:37:27] TIL there's a mobile launch platform in the Pacific ocean. [16:37:28] also you want to PREVENT static from starting fire. It killed the Hindenberg [16:37:37] there used to be one [16:37:44] https://en.wikipedia.org/wiki/Odyssey_(launch_platform) [16:38:02] yes, that is the one [16:38:13] doesn't mention being retired anywhere on the article [16:38:26] rhw platfoem may be ok, the company failed [16:39:28] Althego: then so other company can come along, buy the thing for pennies on the Dollar and do launches for cheap? [16:39:55] imagine if spacex launched from the platform and laded on a drone ship :) [16:41:31] https://www.theverge.com/2018/1/22/16918464/spacex-falcon-heavy-rocket-static-fire-delayed-shutdown [16:41:36] egh [16:42:47] you cant trust americans to do anything right. maybe war, but even that only once in a while [16:44:59] bah to that nationalist nonsense [16:45:28] the Rocket Labs launch was pushed back a whole day because some dumb sailors wouldn't stay out of the range [16:45:50] Humans [16:46:35] "there's some dumb guy with an American accent who keeps shouting on the communications radio, what do you think he wants?" "bah who cares, ocean's big, maintain course" [16:48:33] so much for being private in relying on governmentally funded personnel lol [16:48:34] madmerlyn: There's a common joke circulating around the net about 1 captain refusing to change course and shooting to the other guy that is is bigger and more important and the he can't be bothered to change course... [16:49:04] "I am the biggest ship of fleet X, YOU change course, Over" [16:49:16] reponse: "I am a lighthouse, Over" [16:49:22] the lighthouse joke? probably just urban myth [16:49:57] yeah. But the same game of chicken cause the Halifax explosion... [16:50:02] Gasher: Given that nobody really has built much in the way of private space facilities ... [16:50:16] Rocket Labs did [16:50:22] they built their own spaceport in NZ [16:50:47] manufactures the oxidizer in situ, which I'm sure is standard for spaceports [16:51:05] I'm saying this is a rather recent thing [16:51:07] doesn't sound exciting [16:51:22] but ok, if it's the first [16:51:26] it is exciting, they're going to offer low cost launches for small payload customers [16:51:35] If I said "Private Spaceports" ten years ago, nobody would have believed me [16:51:37] It is exciting [16:51:43] What the coordinates of the Rocket Labs launch site [16:51:55] right now if you have a small payload you rely on piggybacking on a larger payload's launch, which has a lot of intrinsic problems [16:52:08] https://en.wikipedia.org/wiki/List_of_rocket_launch_sites [16:52:27] 39.26S 177.86E [16:52:39] that far north? [16:52:45] you mean south [16:53:07] I was expecting closer to polar circle [16:53:21] problem with piggybacking on a larger launch is you have less determination on the final orbit [16:53:32] and, in partial abort situations, primary payload takes priority [16:53:52] couple instances where a secondary payload was aborted [16:54:39] Rocket Labs remedies that with a smaller rocket that is affordable so the small customers can have more input on their orbital destination and not fall victim to a partial abort [16:55:42] I don't know how/if payload insurance works, but I imagine it might even be cheaper to insure a payload on an Electron than as a secondary payload on a F9, due to the fact that its not a secondary payload [16:56:07] em, but smaller rocket means smaller efficiency i think, no? [16:56:23] not really [16:56:39] RL's last launch had a gross weight of 10.5t [16:56:40] i mean, until certain size [16:56:55] they're estimating a cost for a launch being 4.9M [16:57:28] that's up to 350kg to LEO or 250kg to the moon or a heliocentric orbit [16:58:38] not sure what this efficiency question is, efficiency is determined by payload fraction for the most part, and generally the bigger the rocket the lower the payload fraction tends to be due to the need for additional engine mass [16:59:42] but here is some math [17:00:14] F9's payload fraction, total is 4%, that's including the upper stage's mass [17:00:25] wait, right [17:00:32] Electron's payload fraction is similar [17:03:14] ok, wiki says electron is more conservative, 150 to 225kg to 500km SSO [17:03:23] that still puts its payload fraction around 3% [17:03:43] at a cost that is similar or less than piggybacking on a bigger launch vehicle [17:04:45] RL is planning on putting a ME mission on the moon this quarter too [17:05:06] ME has to land before March 31st to win Lunar X prize I believe [17:05:13] however ME might not be ready, though RL seems to be [17:05:29] RL is using a different tech for the rocket body that is helping with weigh (or so I heard) [17:05:51] carbon fiber [17:05:57] the entire rocket body is carbon fiber [17:06:07] 3d printer Carbon Fibre [17:06:16] (sorry, fiber*) [17:06:21] they 3d print most of the components, including the engine nozzle etc. [17:06:46] https://upload.wikimedia.org/wikipedia/commons/2/2c/Rocket_Lab_Launch_Complex_1_%28Sept_2016%29.jpg [17:07:02] it's kinda neat seeing farm equipment and cows in the foreground of it lol [17:07:20] would've been better if they were sheep though [17:07:25] If they can 'grow' a single 'crystal' of Carbon Fiber, the strength of that thing would be impressive [17:08:17] depending on their manufacturing facility, 3D printing might make construction a bit faster too [17:08:53] no need to roll steel and rivet together and then test and inspect joints [17:09:47] I don't know all the details but I'd bet some of the only parts of the rocket that aren't 3D printed might be the actual fuel tanks inside the rocket body, IIRC it's a kerosene rocket [17:10:02] and maybe some of the fuel lines [17:11:52] Imperfections in a material (anything not perfect) brings down the strenght of the material. [17:12:38] If you could make a single 'crystal' of perfect glass without any impurity it would have between 100x to 100000x the strength [17:13:13] now imagine carbon fiber. For the same strength you could get MUCH lighter material [17:13:37] so even if they can't make it perfect, any reductions in impurities will make the thing better [17:19:32] #KSPOfficial: mode change '+o APlayer' by ChanServ!ChanServ@services.esper.net [17:20:52] so my typing game, I think I want to do like a Missile Command style background [17:21:22] like have it put words on the screen, and each word has a meteor crashing down, and typing it shoots it out of the sky [17:23:20] #KSPOfficial: mode change '+o BPlayer' by ChanServ!ChanServ@services.esper.net [17:33:53] Oooh a typing game [17:33:55] I want to play [17:47:38] well as I develop it I'm sure I'll put links for it here :P [17:49:21] #KSPOfficial: mode change '+o APlayer' by ChanServ!ChanServ@services.esper.net [17:49:51] madmerlyn: The Typing of the dead, Undead Asteroids edition [17:54:06] I have a name for it Merlyn. Mavis Beacon's Alien Defense [17:54:29] https://i.gyazo.com/0e76571bbe61f99c3ef91f61a536d11d.png [17:55:21] i know about gyoza, but what is a gyazo? [17:56:02] and I think my old pocket organizer had a similar game...letters popped up onscreen and you had to type the letter top clear it before the screen filled up. [17:57:42] so I apparently have no internet [17:59:47] how are you online? [17:59:54] idk [18:00:11] well I do have internet but my browser says that I don't [18:01:35] DNS. It's always DNS [18:02:48] well now I have internet [18:02:50] great [18:02:59] but it is very slow [18:03:12] maybe because my grandma has some guest over [18:03:18] change the dns to google temporarily? [18:03:49] you can resolve a site manually and see if the ip works but the address doesnt [18:04:35] ve2dmn: looks like the found a compromise. [18:04:53] But I guess it'll take some time to get everything up and running again for the static fire test [18:09:01] uh [18:09:10] slow internet is worse than no internet [18:09:15] static fire, because they start the rocket with a plastic rod on a cat [18:10:11]
