the origin of "core dumped" |
01:06 |

it comes from magnetic cores in the olden days, purported ly |

core as in magnetic core |

why do people insist on making mods gplv3, if they're clearly building on top of minetest_game and don't add any new concepts? |
02:51 |
sofar |
I guess I'll reimplement it from scratch and release as lgpl2.1..... sigh |

LazyJ |
RealBadAngel, I (and others) have noticed that nodes that use the colorize feature in their code appear blackened when normalmaps are used. Is this fixable? |
17:31 |
LazyJ |
And thanks for the tip about AwesomeBump. That does do a much better job than GIMP. |

rubenwardy joined #minetest |
17:46 |
LazyJ |
Any ideas what increasing the dedicated_server_step would have? How much is too much? |
17:48 |
Calinou |
LazyJ, the more you increase it, the less smooth player movement will appear. |
17:49 |
Calinou |
0.1 is a decent value, but use 0.05 if you can… |
17:49 |
Krock |
It means there will be less packets flying to to the clients |
17:49 |
Calinou |
(my hunger games server uses 0.05) |
17:49 |
Calinou |
many servers can handle that value fine |
17:50 |
LazyJ |
Hmm... Does the 3rd person view give a reasonable depiction of the more smooth/less smooth effects of the dss? |

AndDT joined #minetest |
18:07 |
Calinou |
LazyJ, no, it does not since the third person view's position and animations are entirely client-side |
18:07 |
Calinou |
use another client to see how smooth movement is |
18:07 |
Calinou |
also movement would look smoother if yaw changes were interpolated… it's 2015 and they still aren't :( |
18:09 |
LazyJ |
Given how rigid the avatars are at present, they aren't capable of much motion to be fluid about. Will do some tinkering to try to strike a balance. Thanks ;) |
18:14 |
Calinou |
the ideal would be 0.025 |
18:14 |
Calinou |
(40 FPS) |
18:14 |
Calinou |
but it's probably too taxing on many servers and networks |
18:14 |
Krock |
0.02 (50 FPS) |
18:14 |
Calinou |
(40 FPS networking is what many modern games use) |
18:14 |
Ingar |
4D interpolation is hard |
18:14 |
Calinou |
Krock, 50/60 is definitely too much… for instance, a Warsow server with that framerate (on server) will drop packets like crazy |
18:14 |
Calinou |
default is 20, I bumped it to 40 on my Warsow server :p |
18:15 |
Krock |
Ingar, no, it's just eating damn much CPU when you want to interpolarize it correctly |
18:15 |
Krock |
Calinou, yeah.. Always depends on the amount of the data which is sent every step |
18:15 |
Ingar |
the biggest problem imho is, you're not interpolating |
18:15 |
est31 |
wtf |
18:15 |
Ingar |
you';re extrapolating |
18:15 |
Ingar |
because the next frame is still on the server |
18:15 |
est31 |
why not linear interpolation |
18:15 |
est31 |
done |
18:15 |
Calinou |
Ingar, we need to interpolate position and yaw, that's all |
18:15 |
Ingar |
est31: fail |
18:16 |
Calinou |
our interpolation is not entirely linear btw |
18:16 |
Calinou |
(which is probably a bad thing, it tends to create stuttering) |
18:16 |
est31 |
Ingar, why fail |
18:16 |
est31 |
also, why interpolation at all |
18:16 |
Ingar |
wehave fun doing standard interpolation on rotations |
18:16 |
est31 |
it introduces lag |
18:16 |
Ingar |
*standard linear |
18:16 |
Ingar |
interpolation does not cause lag, by definition |
18:17 |
est31 |
Ingar, you need to know the next value in advance in order to interpolate. |
18:17 |
est31 |
so you have to wait until the server sends you the next yaw value |
18:17 |
Ingar |
est31: as I said earlier |
18:17 |
RealBadAngel |
LazyJ, if one of my PRs will get merge you will be able to define the normal map to use |
18:17 |
est31 |
so by definition, interpolation can only be done offline |
18:17 |
Ingar |
est31: in your case, the lag is casued by having to wait an extra frame, not by the interpolation itself |
18:17 |
Calinou |
only hardcore QuakeWorld players complain about interpolation :P |
18:18 |
Ingar |
est31: yes, that is true |
18:18 |
RealBadAngel |
so it wont collide with texture compositions (read damn shitload of files) |
18:18 |
Calinou |
but yeah, interpolation strength should be a minetest.conf setting |
18:18 |
Ingar |
that;s why trem caleld it "client prediction" :p |
18:18 |
Ingar |
called |
18:18 |
est31 |
Ingar, yes of course, but the interpolation requires it, so adding interpolation introduces lag one way or another |
18:18 |
LazyJ |
Ok. Thanks, RealBadAngel ;) |
18:18 |
Calinou |
Ingar, we interpolate only yaw since only yaw is displayed on players |
18:18 |
Calinou |
no need for pitch |
18:19 |
Ingar |
Calinou: then you might be able to get away with it and extrapolate |
18:19 |
Ingar |
even higher -order based on past frames |
18:20 |
Ingar |
n-polys are fast to interpolate |
18:20 |
LazyJ |
I know there is an Issue posted by... HybridDog? about the blackening of normalmaps but I think he closed it for some reason. Would posting an Issue, myself, with a screenshot make a difference? |
18:20 |
Ingar |
can't remember the name of that algorithm |
18:21 |
|
nrzkt joined #minetest |
18:22 |
est31 |
there are tons of algorithms to do interpolations |
18:22 |
Ingar |
you want one where you just can add a node each frame |
18:22 |
est31 |
the smart ones however require that you need to set the base points irregularly |
18:22 |
est31 |
regular points are bad |
18:22 |
Ingar |
and keep the exponents of the interpolation polynome |
18:23 |
Ingar |
est31: it has been over 15 years since I actually had to study that stuff :p |
18:24 |
Ingar |
it's a bit rusty |
18:24 |
est31 |
I'm doing it right now |
18:24 |
est31 |
could do better though |
18:25 |
Ingar |

LazyJ |
If the num_emerge_threads only deal with mapgen, why does the thread, according to htop, spike to 43% of CPU when I run through an area that has been developed and frequented by players (spawntown) for over two years? |
18:28 |
sofar |
Ingar: vlaams? :^) |
18:28 |
est31 |
LazyJ, I think the emerge threads also do the decompression |
18:28 |
est31 |
but idk, perhaps they spend time with bureocracy |
18:29 |
est31 |
you know filling some internal lists and having O(n^3) complexity or such |
18:29 |
Ingar |
sofar: vollenbak |
18:33 |
LazyJ |
est31, decompression of what? I thought sqlite wasn't compressed? |
18:33 |
est31 |
LazyJ, it is compressed |
18:33 |
est31 |
it would be totally horrible if map weren't |
18:34 |
est31 |
compression could do better though |
18:34 |
est31 |
16 as block size isn't really efficient |
18:34 |
est31 |
but shrug, it is better than nothing |
18:35 |
Ingar |
put home on NFS. load large minecraft map with lots of mods. get coffee. |
18:35 |

Ok, thanks. ;) |
18:36 |

LazyJ, i tester uncompressed mapblocks in DB |
18:36 |
nrzkt |
it's 100 to 400x larger |
18:36 |
nrzkt |
and the database transfer cost more than comprssing the data |
18:37 |
LazyJ |
nrzkt, thanks. I've been trying out various settings over the past few weeks. One of my greatest frustrations is not understanding what affect the settings may or may not have and having no way to measure what, if anything, that they are doing. |

yeah, used to but since I use Git it breaks all the time |
21:18 |

well its unfair |
21:18 |

if you get red screen you cant see |
21:18 |

if you disable client side you have an advantage against players with a screen |

it should be configurable anyway |

now I have another error |
21:28 |
dadix |
wrong passord |
21:29 |
dadix |
it's strange because with the same password I can connect from the GUI server |
21:30 |
dadix |
but wen I open the server from terminal and i want to open the game with my client I have this error |
21:30 |
dadix |
with : wrong password |

dadix: your terminal server uses differend world/user data? |

oh nice |

Rust is a nice thing |
21:40 |
est31 |
only bigger problem I have with it is that Cargo and all this stuff doesnt have debian packages |
21:40 |
est31 |
and one has to trust the rust team to have built trustable compiler |
21:41 |
est31 |
as the rust compiler is written in rust, you can't bootstrap |
21:42 |
est31 |
if you really wanted to rebuild the rust compiler you would have to roll back the git to the ocaml days |
21:42 |
est31 |
back then it was programmed in ocaml so you can use the ocaml compiler to compile it |
21:42 |
est31 |
then you have to continuously rebuild the compiler, with increasing git tags |
21:43 |
est31 |
I think the chain is around 200-400 rebuilds |
21:43 |
est31 |
to comparison: gcc is written in c++ (most parts are still c) and llvm is written in c++ as well |
21:44 |
est31 |
but there are many many c compilers |
21:44 |
est31 |
and there is an old version of gcc which can be used to build newer versions of it |
21:44 |
est31 |
so 3 steps maximum to get gcc / llvm from a c compiler |
21:45 |
est31 |
but I do think that the rust project is one into the right direction. |
21:49 |
* edj |
doesn't think Rust will ever gain significant traction because the syntax is too different. |

hrm, how hard would it be to build a barebones rust compiler, written in C or similar, that perhaps doesn't optimize much and perhaps doesn't fully check type correctness? |
21:51 |
kahrl |
but that is enough to compile the actual rust compiler? |
21:51 |
est31 |
kahrl, idk, rust the compiler has around 200k lines |
21:51 |
est31 |
but yeah, in fact if I had tons of time I would even start such a project. |
21:51 |
est31 |
it would be himmelfahrtskommando i know |
21:54 |
dadix |
who knows where is installed minetest-server? |
21:54 |
dadix |
which folder? |
21:55 |
est31 |
dadix, dpkg -L minetest-server |
21:57 |
kahrl |
or if it wasn't installed through dpkg, you could try "which minetest-server" or "locate minetest-server" |
21:57 |
dadix |
i installed from ppa |
21:58 |
kahrl |
then the dpkg command should work |
21:59 |
dadix |
thanks |
