hmmmm, new pull request for mgv5 overgen, so far seems to work okay https://github.com/minetest/minetest/pull/1842 |
| 01:29 |
paramat |
also, when i access eased noise at point i get a warning during build, pasted here https://github.com/minetest/minetest/pull/1834#issuecomment-63128703 |

hmmmm |
uh oh, that can't be too good |

hmmmm |
lol |
| 02:17 |
hmmmm |
paramat, NoisePerlin3DEased() always returns 1 |
| 02:17 |
hmmmm |
that's because I messed up a parenthesis in the macro and the resulting expression happened to be valid since the last parameter is optonal |
| 02:17 |
hmmmm |
so it's float noise = (f(x,y,z), 1) |
| 02:20 |
hmmmm |
try it now |
| 02:20 |
paramat |
okay good! |
| 02:20 |
hmmmm |
hah that was quite a gotcha |
| 02:24 |
paramat |
*looks* ahh i was actually looking at those brackets wondering if they were correct |
| 03:08 |
paramat |
hmmmm, it works now. the eased top-down per-node search seems fast, timed earlier at ~1ms |

nevermind, i thought there was a possible bug from not checking the return value of readConfigFile |

although the port number could probably be made into a #define constant rather than just a numerical literal |
| 07:28 |
hmmmm |
and address could probably default to localhost |
| 07:29 |
sfan5 |
why would anybody want to change the default port? |
| 07:31 |
hmmmm |
it has more to do with clarity than anything else |

Sokomine |
hi. i still have a problem that can't really be solved well, and i'm a bit cueless as to how to proceed (apart from ignoring the problem and claiming it can't be done reliably): i want to mirror buildings along the x- or z-axis in order to increase variety. as long as full nodes are concerned, that's no problem at all. but after that, it gets complicated and depends on the actual shape of the nodebox/model. there may not even e |
| 17:53 |
Sokomine |
just got told that something was missing, so: there may not even exist a node that might act as a mirrored representation |
| 17:54 |
Sokomine |
as far as doors go, there is a mirrored representation - which is another node |
| 18:16 |
|
MinetestForFun joined #minetest-dev |
| 18:18 |
kahrl |
Sokomine: a low-tech solution is to simply have two versions of each schematic - a normal one and a mirrored one |
| 18:19 |
kahrl |
that might even be best in terms of performance, as you don't need to map node ids at runtime |
| 18:22 |
Sokomine |
that might be best, yes. it wouldn't require any additional ressources. still - some nodes do not require a mirrored version, and there'd be no helpful naming convention |
| 18:24 |
Sokomine |
it doesn't sound complex at first to mirror a house. it's just that it ends up beeing exception after exception (and then there are mods/mapgens/games which call the same things diffrently for no apparent reason..) |

i'm actually laughing right now, love it |

hmmmm |
I have a decent way of sabotaging freeminer (at least on non-freeminer servers) |
| 21:54 |
hmmmm |
but it requires downloading and running binary blobs from a server |
| 21:55 |
celeron55 |
we don't need to sabotage freeminer, it sabotages itself |

actually we could make this open source |

( he reverted the cmmit afterwards ) |
| 21:57 |
hmmmm |
I was thinking of minetest downloading a module downloaded from the servers that periodically scans for strings in the working executable's memory and if it sees freeminer, changes it to "screwed up miner" or something |
| 21:57 |
celeron55 |
and competition is for the best anyway; if someone can compete with minetest by adding memory leaks, then maybe minetest isn't very competitive... |
| 21:57 |
sfan5 |
s/,/?/ |
| 21:58 |
hmmmm |
and it sends back a signed hash of what's being executed |
| 21:59 |
Krock |
hmmmm, nice idea |
| 21:59 |
hmmmm |
can't block execution without modifying the executable in memory, which means changing the signature |
| 21:59 |
hmmmm |
so this way it wouldn't be dependent on the minetest executable's signature, just the module loaded |
| 22:00 |
hmmmm |
hmm |
| 22:00 |
hmmmm |
freeminer could work around this messily by allocating all strings that say "freeminer" in a manually-allocated piece of memory with read-only permissions, and the segfault handler would just detect the change and it'd modify the text back to freeminer |
| 22:01 |
RealBadAngel |
http://i.imgur.com/5cQT16m.png |
| 22:01 |
RealBadAngel |
how do you like that? |
| 22:01 |
sfan5 |
why would it segfault on read-only memory? |
| 22:01 |
hmmmm |
we could hook the segfault handler first |
| 22:01 |
Krock |
RealBadAngel, after the wieldhand, the lua entities? |
| 22:01 |
hmmmm |
writing to read only memory is a memory violation |
| 22:02 |
sfan5 |
oh you want to write somewhere |
| 22:02 |
hmmmm |
kool |
| 22:02 |
sfan5 |
makes sense then |
| 22:02 |
hmmmm |
RealBadAngel, nice |
| 22:02 |
RealBadAngel |
this is slightly fine tuned wielded |
| 22:02 |
hmmmm |
yeah, sfan5, we're overwriting strings containing the phrase "freeminer" to "f'd up miner" or something |
| 22:02 |
hmmmm |
in this hypothetical protection system |
| 22:03 |
sfan5 |
if you want it to be secure you need to get TPM involved |
| 22:03 |
hmmmm |
of course |

casimir joined #minetest-dev |
| 22:03 |
hmmmm |
there's lots of ways this could be made bulletproof, but all of those require cryptographic signing of the main executable which is not plausible |
| 22:04 |
hmmmm |
and of course all of it is extremely platform specific |
