06:40 <flayer> nice

06:40 <flayer> i made a VTOL craft using the rotation servos

08:52 <Althego> https://www.kerbalspaceprogram.com/dev-diaries/developer-insights-10-collisions/

08:54 <flayer> from studying fluid mechanics on supercomputers to working on kerbal space program...

10:20 <Mat2ch> This is good news.

10:22 <Mat2ch> buuuuttttttt

10:22 <Mat2ch> they are still using floats.

10:22 <Mat2ch> Funny.

10:23 <Althego> hehe

10:23 <Mat2ch> It is really funny how nobody seems to be able to grasp the idea of using fixed point calculations for this problem.

10:23 <Mat2ch> Probably the same old story as always: We always did it this way.

10:24 <Althego> hehe

10:24 <Althego> not always

10:24 <Mat2ch> Or: That's how everyone else is doing it!

10:24 <Althego> i ported simulator code from the early 70s, that used fixed point, because they didnt have anything else

10:25 <Althego> was full of different precision numbers and always had to normalize them for any operation

10:25 <Mat2ch> How many bits did they have?

10:25 <Mat2ch> 8?

10:26 <Izaya> probably 32

10:26 <Althego> 16 hw, but could use 31 bits if needed to. (31 because of double sign bits)

10:26 <Althego> even had hw division

10:27 <Izaya> fixed point lets you pretend numbers are just integers doesn't it?

10:27 <Althego> but amazingly they had to write all trigonometric functions and matrix operations in asm

10:28 <Mat2ch> Izaya: the other way round. You just pretend that your integers have a point in them :D

10:28 <Mat2ch> And if you are dealing with money you should do that. Always.

10:28 <Izaya> this is the same picture

10:31 <Mat2ch> With 64 bit and two decimals after the point you can have this: 184 467 440 737 095 516.15 mm

10:31 <Mat2ch> This is enough to simulate the whole solar system. (If I didn't make a mistake somewhere. Those numbers are huge)

10:31 <Mat2ch> and millimeter precising would be enough for a game like KSP. So you get even more size.

10:32 <Izaya> even 4 bits of sub-mm would be fine

10:32 <Izaya> 60+4 bits

10:33 <Mat2ch> mm would be fine!

10:33 <Mat2ch> You would never notice in-game...

10:35 <Althego> ... and i would have gotten away with it, if it werent for those meddling kids

15:06 <darsie> What's the effect of finding the desert air strip?

15:14 <darsie> https://i.postimg.cc/pv7whjJ6/screenshot308.png

15:39 <Mat2ch> you can launch from there now.

15:40 <FLHerne> "You can only launch from Dessert if you enable Allow other Launchsites in the Difficulty Settings. When enabled you can launch a plane from the SPH via the dropdown menu under the Launch button. When you hover over it, a menu appears with available launch sites. Select the arrow next to Dessert Airfield to launch from there."

15:40 <FLHerne> ^ wiki

15:48 <Mat2ch> Hm. I thought in career mode at least you've got to discover them, too.

15:55 <UmbralRaptop> You get a discovery notification in sandbox mode if you launch from there

15:57 <UmbralRaptop> Uh, has the wiki been updated / someone tested how it works if you 'discover' a eg: the desert airfield with additional launch sites turned off?

16:01 <darsie> Mat2ch: But I can't: https://i.postimg.cc/fDfvx4mr/screenshot309.png

16:01 <darsie> I do have the Crater launch site.

16:03 <darsie> Ok, it works with enable alternate launch sites.

16:03 <darsie> But why did I get the Crater launch site when it was disabled?

16:08 <darsie> I got woomerang, too, now.

21:40 <Mat2ch> darsie: I have no idea.
