hmmmm, i'll push #2640 soon, i removed checks for p and pmax for reasons given in the thread, back soon |

oops heh |
| 01:46 |
paramat |
done |
| 01:48 |
hmmmm |
wait you removed the checks? |
| 01:48 |
hmmmm |
hello cutoffs :| |
| 01:49 |
paramat |
yeah i know |
| 01:49 |
paramat |
sorry, you said the check for p was redundant |
| 01:50 |
hmmmm |
yeah the check for the point, not the area |
| 01:50 |
hmmmm |
contains(VoxelArea{pmin, pmax}) implies contains(p) |
| 01:50 |
paramat |
ah, my original PR checked p and pmax |
| 01:50 |
paramat |
i misunderstood |
| 01:50 |
hmmmm |
well that's okay |
| 01:51 |
paramat |
still, see reasons in thread, you agree? |
| 01:51 |
hmmmm |
i'm going to modify a few other things in that file soon |

hmmmm |
i thought it just said that it was slow or something like that |
| 01:52 |
paramat |
i think speed is more important than checks for cutoffs |
| 01:53 |
hmmmm |
do you realize the difference in magnitude.. |
| 01:53 |
paramat |
especially since cutoffs due to rotation are not checked for anyway |
| 01:53 |
hmmmm |
do you mind if I add it back in when I add in the rotation check? |
| 01:53 |
paramat |
yeah small |
| 01:53 |
paramat |
no i don't mind =) |
| 01:53 |
hmmmm |
ok |
| 01:55 |
paramat |
so you will be checking for cutoffs due to rotation? impressive |
| 01:56 |
hmmmm |
it's not hard |
| 01:58 |
paramat |
okay. now, game#310 has approval from the team, is rebased and squashed, i'm considering pushing it for them since they're so busy ..? |

| 02:05 |
paramat |
well i'm gonna do it, i even asked nore yesterday and got no response |
| 02:06 |
hmmmm |
fine by me, i mean i don't do anything with minetest_game |
| 02:10 |
paramat |
oh hang on, some of ShadowNinja's line notes have not been acted on, so it needs improving before pushing |

| 05:04 |
hmmmm |
hmm |
| 05:04 |
hmmmm |
i look at stuff like this http://i.imgur.com/HFEftHA.jpg and it makes me wonder if we've been doing it wrong |
| 05:05 |
hmmmm |
should we be using 2d noise as the base terrain and then 3d noise for "detail"? |
| 05:05 |
hmmmm |
although I suppose the current algorithms already do this to an extent |
| 05:07 |
hmmmm |
how can the 2d noise shape be made more prevalent over the 3d |
| 05:08 |
hmmmm |
what if the base terrain was pure 2d and then for terrain detail, the same 2d noise is multiplied by 3d noise to create the detail |
| 05:09 |
hmmmm |
so it'd be like placing mapgen v5 on top of a mapgen v6 map |
| 05:09 |
hmmmm |
sorta |
| 05:09 |
hmmmm |
except the terrain would be synchronized |
| 05:09 |
hmmmm |
i gotta try this out but i'm stuck doing unit test crap |

'stuck'? you're not at work, do what you feel |

it's a priority for me |

hmmmm |
I hate work right now |

hmmmm |
i feel like i'm getting micromanaged |
| 05:36 |
paramat |
my river valleys use 2d valley noise to multiply 3d mountain noise, for a smooth blend from one to the other |
| 05:43 |
paramat |
something like (1 + 2Dnoise) * 3Dnoise |
| 05:44 |
hmmmm |
that's what mapgen v5 already does |
| 05:44 |
hmmmm |
hmm what I'm talking about is hard to explain i think, i just need to show you |

hi all |
| 14:15 |
neoascetic |
github supports contributors notice: https://github.com/blog/1184-contributing-guidelines |
| 14:16 |
neoascetic |
could someone add CONTRIBUTORS.{md,txt} to the repo with style guides/etc? |
| 14:17 |
neoascetic |
I think it is better to have guidelines in the repo instead than somewhere on wiki |

sometimes, C is very weird |
| 15:22 |
est31 |
I have these 4 files: https://github.com/est31/csrp-gmp/tree/master/sha |
| 15:23 |
est31 |
where is the implementation for SHA256_Init?? |
| 15:23 |
sfan5 |
remember how i said just ripping some code out of a big project is not a good idea |
| 15:24 |
sfan5 |
this is exactly what happens |
| 15:24 |
sfan5 |
you use some code |
| 15:24 |
est31 |
it works very well |
| 15:24 |
sfan5 |
then somehow something is missing |
| 15:24 |
sfan5 |
or you don't know where it is |
| 15:24 |
sfan5 |
or it breaks for some reason |
| 15:24 |
sfan5 |
or .... |
| 15:25 |
est31 |
I just wanted to add SHA-1 support so that I can test whether we are conformant with RFC 5054 |
| 15:25 |
est31 |
(in theory) |
| 15:25 |
est31 |
I mean we dont need that conformance, but its a good way to check whether all computations are right |
| 15:25 |
sfan5 |
you mean whether sha1.cpp is right? |
| 15:25 |
Etzos |
Line 33-66. |
| 15:26 |
est31 |
Etzos, which file? |
| 15:26 |
Etzos |
sha256.c |
| 15:26 |
est31 |
ah I see |
| 15:26 |
est31 |
thanks |
| 15:27 |
* est31 |
should read more carefully |
| 15:27 |
sfan5 |
est31: <sfan5> you mean whether sha1.cpp is right? |
| 15:27 |
est31 |
no that is ok |
| 15:27 |
est31 |
I mean I trust that |
| 15:27 |
est31 |
I only want to check the srp implementation |
| 15:28 |
sfan5 |
sha1.cpp is correct btw |
| 15:28 |
est31 |
and the test vectors in the RFC rely on sha-1 |
| 15:33 |
est31 |
I know of sha1.cpp |
| 15:33 |
est31 |
but its c++ |
| 15:33 |
est31 |
and the test file is c based |

sfan5, I think you have convinced me. I now think that libnettle is no bad option at all. |
| 21:14 |
est31 |
Right now it might only be used for hashing, but later we can use it for encryption too. |
| 21:15 |
est31 |
However, before its a back and forth, I suggest first running with the "ripped out" sha implementation, and then adding nettle when adding encryption. |
