[15:02:01] c++ is getting increasingly convoluted [15:02:13] which language has killed more people, C or JavaScript [15:02:14] yes js shouldnt exist [15:03:51] C is more likely to be used in context where there is greater potential for gore [15:05:05] well... I don't know in what language it was coded but a PDP-11 Therac25 medical device actually delivered the wrong dose of radiation and killed someone [15:05:25] more than one person I think [15:05:31] 3 [15:05:51] i think those accidents happened much later too [15:05:53] but in one case it was a brain tumor and the patient neve woke up [15:05:54] with some ct [15:05:56] maybe ge, [15:06:02] javascript is more likely to ruin you financially than to cut off your limbs [15:06:05] I guess [15:06:31] "The high-current electron beam struck the patients with approximately 100 times the intended dose of radiation, and over a narrower area, delivering a potentially lethal dose of beta radiation." [15:07:18] with pdp-11 it was probably c or fortran [15:07:37] Can someone explain how I can insert a picture in a reply on the KSP forum? [15:08:08] Guest96656: easiest way is to use an image sharing site and link to that [15:08:11] Guest96656, if you can't attach it upload it to imgur or some other hoster and embed it [15:08:12] (like imgur) [15:08:24] thanks! [15:09:26] I wouldn't count a language as having killed someone unless it was a consequence of the language design [15:11:01] KrimZon_2: it was a race condition if my memory is correct. That 'could' have been prevented with another language, but remember that this was in 1980s with a PDP-11... [15:11:19] KrimZon_2, well null has been called the most expensive mistake ever [15:13:44] Mr Null [15:14:48] GlassYuri: the tyranny of the default, and without input, Null is always the default. Just look at Null Island [15:17:01] hehe null island [15:17:09] i went there so many times [15:17:14] I'd define null as its own type, so when you try to assign null to something that isn't nulltype you get a type error.

[19:50:08] Perhaps.. or perhaps not, planet does have a lot of plantlife... was never determined what kind of fuel is used. [19:50:32] I doubt we will cross the 4 millions+ light-years distance between here and outside the local cluster group [19:51:10] maybe not us [19:51:17] but some kind of ai descendants [19:51:33] Sure.

[19:54:43] lol.. its only just space [19:55:28] JCB: it's fun to speculate, but I doubt with our current understanding of the universe we would go outside the solar system [19:55:31] There's a lot more to space than space. Most of it's dark energy I guess? [19:55:44] Space is hard and BIG. REAL BIG. [19:55:50] sure.. could cross that distance, but there are other things gotta worry about too. Time.. dilation.. particles.. [19:56:02] radiation [19:56:22] Voyager 1/2 pretty much there, took nearly same time I've been alive [19:56:27] ve2dmn: If you could make interplanetary travel pedestrian, I'm sure you'd have the radiation thing figured out by the time you want to do interstellar. [19:56:41] JCB: Time dilation, on extreme scales, would be extraordinarily helpful. [19:57:03] go out there, come back, find out 4billion years passed [19:57:04] Though getting to high fractions of c would be problematic. [19:57:29] JCB: That's not quite how it'd work unless you're traveling intergalactic. [19:57:37] Scolar_Visari: which is why I said earlier that we will never leave the local cluster [19:57:52] might not even have to deal with distances... just jump instantly, but then there has been talk about disconnect of time between two locations placed such a large distance [19:57:59] Though I believe a return journey is typically not a consideration in any quasi-plausible discussion of interstellar travel. [19:58:29] ve2dmn: I was gone, though I wouldn't say never, particularly if human-sicle shenanigans ever become a thing. [19:59:00] lol.. book I have talks about using black holes as a power source.... powering interstellar ships [19:59:10] Or, Heaven forbid, antimatter rockets with thrust greater than a baby's fart. [19:59:20] You really think we could build a ship that travel to a fraction of c and that last for 4 millions+ years? [19:59:37] One day? Why not? [19:59:50] may not even need spaceships... [20:00:21] We have trouble building things that last 1000 years... much less 10000 [20:00:33] ve2dmn: So long as you don't violate causality and do it before the Universe's expansion physically forbids it. [20:00:49] Action: Scolar_Visari notes applying modern technology to a problem in the far future is extraordinarily problematic. [20:00:56] ve2dmn you are talking about a ten-fold in time... human race hasn't exactly been around super long time [20:01:07] we can build things to last several thousand years [20:01:07] It'd be like us trying to apply Egyptian architecture to modern skyscraper construction. [20:01:12] butthey are made of stone and not machines [20:01:29] Action: ve2dmn shrugs [20:02:03] space environment is a relatively new thing for us. making something to last on Earth as opposed to in space presents different challenges. [20:02:05] I just don't see it with our current understanding of how things work [20:02:27] Action: Scolar_Visari ponders using Psi Operative stasis fields. [20:02:40] skyscrapes.. stone.. isn't concrete just a version of stone? [20:02:53] JCB: Skyscrapers typically rely more on steel than stone. [20:03:03] You really couldn't *get* skyscrapers without lots of steel, in fact. [20:03:11] And modern ones typically use lots of glass. [20:03:21] ok so some steal, sure.. [20:03:36] mind you, japanese have managed to make houses that don't even use nails [20:03:42] Action: Scolar_Visari points at the Empire State Building, for instance, using steel for its strength and employing the limestone mostly for decoration as it doesn't carry the weight of the building. [20:03:51] JCB: That's true with most historical cultures. [20:03:53] Steel was made from things that came from the earth too :P [20:04:14] theres bucnh of housing styles that doesnt [20:04:20] a lot of the towers going up over here, concrete and steel reinforcement [20:04:48] Action: Scolar_Visari points to the waddle and daub style of housing popular in Medieval Europe, relying mostly on sticks held together with a mixture of poo and horse hair. [20:06:09] Scolar_Visari seen a video on one of those... economical, but the stench... when people could afford, they made some improvements on things. Stone was also used [20:06:23] in old days people would burn down house theyre moving out in order to get nails back [20:06:42] Gotta wonder what kept our ancestors back from the tech explosion nowadays. [20:07:03] knowledge [20:07:04] sigh... still get the occasional arsonist.. [20:07:13] or the lack of it [20:07:19] maybe even some people playing dirty, forcing redevelopments [20:07:20] Draconiator: no science [20:07:32] also, keeping discoveries secret [20:07:58] partly knowledge, partly survival, partly some people felt that religion and serving the lord was more priority [20:07:59] Rolf: That's not really a thing throughout most history aside from very rare examples ala the secret (albeit poorly kept) production of silk. [20:08:58] Keeping Greek Fire secret, for example, was likely one of the reasons the Roman Empire could hardly produce much of it. [20:09:08] I'm thinking it also took critical mass to get the bass rolling on the science [20:10:10] there was a number of factors... [20:10:27] quite a bit of science was actually repressed at times [20:10:34] JCB: That's more a myth than reality. [20:10:35] bass? ball rolling. Stupid brain [20:11:21] Action: Scolar_Visari wishes there was some way the Dark Ages myths could be taken out back and hanged and quartered. [20:11:41] https://en.wikipedia.org/wiki/Scientific_Revolution [20:12:05] I only know some things... [20:12:35] Action: Scolar_Visari notes the time frame in the link covers the period before and after the Reformation and Counter Reformation. [20:13:29] I even read something that said our LEDs today were reverse-engineered from the Roswell UFO. Do I believe that/ no. lol [20:14:17] Draconiator: That's a myth. They actually have their basis in technology recovered from a captured Sectoid circa 1960s. [20:14:27] Men in Black RPG book says, almost all of the tech now, was brought from other races/worlds... or something. [20:14:40] didnt you know, everything was reverse engineered from time machine found in 1700s [20:14:50] no aliens. just humans [20:15:28] JCB: As much in good humor as that is, a lot of people in the past and modernity (IE Chariots of the Gods) have used the same claims in serious attacks on cultures deemed too stupid to have developed things on their own like the Great Pyramids. [20:15:32] meh.. just thankful for some things we have... social media? Ugh... like I got time for that these days? [20:15:45] "Hey Gorble, have the humans recieved our declaration of war?" "They have Yable, but they play them in places called Clubs, and they call it Dubstep now. [20:15:47] " [20:16:00] ;P [20:16:37] are whales smarter than humans? [20:16:57] More seriously: Technology wasn't reverse engineered. We simply bought it off the Bentusi. [20:17:03] hehe [20:17:11] https://pics.me.me/robots-read-news-an-occasional-web-comic-by-scott-adams-17647230.png [20:17:59] Action: Scolar_Visari shudders at the mention of Scott Adams in a discussion of science. [20:18:12] I don't have answers for everything... I do know to things, internet has a lot more stuff than I do. And I need food soon. [20:19:04] The internet has any answer you want. Some more accurate than others. [20:19:39] Action: Scolar_Visari considers the implementation of Wikipedia:Identifying reliable sources on a global scale. [20:19:44] internet also poses a lot of problems as well.. goes bothways [20:21:50] "SpaceX promised to fly tourists to the Moon. How's that going?" No they did not. [20:22:25] "Nothing else has been announced officially" Except for the cancellation of any and all plans to ever launch a manned vessel on the Falcon Heavy. [20:23:39] moon tourists... has me looking for my mun cruise ship... [20:24:50] SpaceX was solicited by private individuals for a Lunar mission, but it opted not to pursue them beyond what appears to have been back of the envelope planning. I'm unsure as to why this story continues to be incorrectly covered. [20:26:28] ah found it.. [20:27:14] one career, I had something like 12 tourist jump out of the woodwork. 2 wanted kerbin orbit, 10 wanted mun orbit.. [20:27:48] somehow managed to build, launch a craft with only lvl2 pad and VAB... [20:29:16] What on Earth . . . ? "NASA is 100% safe and 100% boring. They should ask for volunteers for a 95% safe orbital system at 25% cost of the 100% safe system. Solid rockets are the way to go with a robust capsule eject system." [20:29:35] So . . . NASA's already done exactly what this person wanted? [20:29:57] sorry to burst the bubble, going to space has always been considered not safe... [20:30:19] JCB: It's probably as safe as driving. [20:30:21] then again, never has been walking across the street.. [20:30:46] Though, ahem, solid fuel LES have already been a thing for a while now, not that they're the end-all to LES. [20:31:04] Action: Scolar_Visari points to CST-100 and Dragon V2 liquid fuel escape rockets. [20:31:30] You can never eliminate risk, only manage it [20:33:30] any case.. gotta go.. [20:33:57] Oh dear. "No plans whatsoever to create faster engines to send probes to other star systems. No plans to deflect killer asteroids. All we do spends billions peeping into Space with multiple telescopes, that's it!" [20:34:22] Action: Scolar_Visari hides the papers on asteroid deflection strategies. [20:36:35] New rule: Any time any one ever mentions, "faster engines" in the context of spaceflight, they probably haven't a clue as to what they're talking about. [20:39:54] It sucks in air https://www.bbc.com/news/science-environment-44396781 [20:40:00] Wasn't there a way to remote control a probe from a nearby crewed vessel, no link back to kerbin required? [20:43:31] There still should be. [20:43:52] They appear to require a minimum number of pilots, however. [20:44:43] Older but probably relevant https://www.youtube.com/watch?v=2gJxljWQO1U [20:44:43] YouTube - How to do remote control with pilots in Kerbal Space Program 1.2 [20:44:45] Just reading up on it (why isn't that on KSPedia?)... [20:45:02] schnobs: I've noticed it's not been up to date on a lot of stuff (such as new parts). [20:45:44] you need a 2.5m Capsule or Lander Can to *give* control, plus a spare pilot and relay antenna. Most everything can take it, even cockpits. [20:48:19] Action: Scolar_Visari would think an in-game pedia ala the Civpedia would also be helpful. [20:49:17] Wouldn't it be nice? That's what I was hoping for when I first heard of KSPedia. [20:54:30] Heck, even the Total War games have a -pedia now. [20:54:56] Though, nonsensically, one that you must be online to use. Heaven forbid they re-integrate an offline one again. [20:57:11] Been a long while since i touched that. It's easy to add a -pedia, but for content and usefulness, Civ sets the benchmark I think. [20:57:53] The City Builder games (Caesar III, Pharaoh, etc.) had pretty good in game encylopedias to match their novel-length manuals. [20:58:02] And that was starting in the 90's! [20:58:23] Action: Scolar_Visari is still a bit disappointed Stellaris didn't add one given the amount of writing that went into its other content. [21:00:11] Well, back in the 90s it was probaly more necessary. In my neck of the woods, (affordable) internet flatrates didn't turn up until y2k or so. [21:01:26] It is irritating in modern games to have online-only encyclopedias, though, particularly since it means opening up a memory eating browser. [21:01:43] It's like Creative Assembly forgot how to make in-game windows . . .
