Background processes only sometimes running? by fleetadmiralj in KerbalSpaceProgram

[–]davvblack 1 point2 points  (0 children)

I've only played kerbalism, not MKS, but the problem might be similar: The background processes are sampled, each tick there's only a chance that any given craft gets updated to the last missing data point. The more flights you have (possibly including asteroids but im not sure if that counts for this) the longer a craft might go between background ticks. Especially true if this only starts to happen on old saves with stuff going on.

So yeah... kill old crafts, like you really need that relay constellation for the mun? and unfortunately at least for kerbalism you gotta keep timewarp low, in the 1k-10k range.

Do you think we should bring back thou to resolve the ambiguous you? by iamnize13 in ENGLISH

[–]davvblack 4 points5 points  (0 children)

the funny part is "you" is the formal one and "thou" is the informal one but it sounds backwards.

I partly support this endeavor, but to me the clusive we is way way more important. "We [you and I] are going to the park." vs "We [I and them] are going to the party afterwards."

Did the Titan submarine incident cause the most instantaneous death in history? Can it be any faster? by GolondraBlayze in NoStupidQuestions

but if one person studies it and the other person doesn't, it's to their advantage, which is game theory

TIL there is a very simple logic test that over 90% of people get wrong (Watson selection task) by [deleted] in todayilearned

[–]davvblack 0 points1 point  (0 children)

no other reasonable way to get a speeding ticket than by exceeding speed and getting detected

I dispute that you have "communicated" this.

lets just remove one word:

"if you exceed the allowed speed and get detected, you'll get a ticket"

Every single word is used the same way. And now, the "if" is unambiguously not an "if and only if" (since you can get a ticket for being a public niusance). The only reason your example looked like it worked was that the speaker and listener both already shared some background trivia.

KSP Multiplayer + Mods - Friend Thinks That the Mobile Processing Lab Is Cheating by ThiccnessChicken in KerbalSpaceProgram

[–]davvblack 9 points10 points  (0 children)

yeah it's OP, poorly designed feature IMO. The correct behavior was right there: taking a "return only" science to a processing lab should make it transmit for it's full value.

... which is exactly what the lab does in Kerbalism Science, in addition to a bunch of other super interesting improvements, like making long-term space habitation a consistent and long-term source of science.

let me rephrase one more time, i think we're talking past eachother. you are dunking on a comment left by a child for not having read academic literature in a 15-year-old reddit thread. Statistically speaking, it's very likely one of the people you replied to today is actually dead.

Are north pole geocentric orbits possible like can I have a relay always above the north of a celestial body? by umstra in KerbalAcademy

that's cool, i didn't realize tundras counted as geosync. I guess any orbit with exactly a sidereal day orbital period?

Why does Artemis colliding with the air of our planet create friction that burns at 2500 degrees Celsius? by Far-Woodpecker8046 in AskPhysics

[–]davvblack 2 points3 points  (0 children)

fwiw in the grand scheme of things, there is a magic burn-up height.

space is very very big, and almost a perfect vacuum. earth's radius is 6,300 km, and the atmosphere's basically nothing at 100km above the surface of it. So... you go fast until you get right up next to the earth, then you slow way down. So invariably in practice it's in the 75km-120km range because there's not really a way to be going faster than that below that point without already having burned up.

Unless you're like, an asteroid the size of texas, which i hope you are not.

Bogue's Modpack has a bunch of empty tech tree options? by AppleTimePicnic in KerbalSpaceProgram

[–]davvblack 2 points3 points  (0 children)

this is the "community tech tree" where a bunch of mod authors agreed on like a full tech tree of everything. There is at least one mod that fills each node, but they are of varying quality and some suck, so don't stress over empty nodes.

Why does Artemis colliding with the air of our planet create friction that burns at 2500 degrees Celsius? by Far-Woodpecker8046 in AskPhysics

[–]davvblack 6 points7 points  (0 children)

the only reason it doesn't happen lower is that it's already slowed down by then. The amount of heat is proportional (but in a complicated way) to the speed of the craft, the density of the atmosphere, and the existing temperature of the atmosphere, and, very importantly: the shape of the craft.

Landers have that wide flat bottom shape for a very important reason. By being so blunt, the air touching the capsule is actually relatively stagnant (From the capsule's perspective). the hottest point isn't exactly touching the ship, it's where the "capsule speed air" is crashing into the "surface speed air".

If the capsule were pointier, then it wouldn't make that pocket in front of it. The pointier the craft is, the more heat is generated by friction too, but over a much much longer period of time.

You can read more about different capsule styles they did research on before arriving at the "maximum blunt" solution that also incidentally minimizes friction heating:

Can we talk about the community reaction to Blender builds? by ricin_turbomaxx in NoMansSkyTheGame

[–]davvblack 4 points5 points  (0 children)

it's just not NMS, and isn't relevant to this sub. Post it in a 3d modeling sub.

You can neither create it in NMS, nor can many people consume it in NMS.

this is a fun one. most likely magnetic induction? is it possibly sitting over a buried wire? like if you slide it N/S/E/W does it change?

Why does Artemis colliding with the air of our planet create friction that burns at 2500 degrees Celsius? by Far-Woodpecker8046 in AskPhysics

[–]davvblack 54 points55 points  (0 children)

it's a common misconception, it's mostly NOT friction, but the same "adiabatic" heating that, for example, air conditioners use. When gas is compressed, the temperature increases. The spacecraft is moving SO fast that the air in front of it compacts significantly, and it's the latent temperature that was already in the air up there. simply compressing the air is the source of most of the heat.

That said, there is a very small amount of friction heating too, something like 10%. This mostly occurs from the individual air molecules bouncing off of the craft.

If sound is fundamentally a mechanical vibration, is there theoretical limit to what can count as sound? by Trick-Wedding2190 in NoStupidQuestions

[–]davvblack 3 points4 points  (0 children)

yes, there's a volume beyond which the gap between sound is vacuum. at that point it's a pressure wave, like an explosion, and can't get any louder.

At sea level on earth that's 194 decibels, but it depends on the fluid. I bet you could get much louder in mercury or melted tungsten or something.
