00:02 paramat the only recommeded app is the official 'minetest for android phone' app
00:03 piesquared secure.trusted_mods = irc
00:03 piesquared irc.server = irc.freenode.net
00:03 piesquared irc.channel = ##PiSurvival
00:03 piesquared irc.nick = PiSurvival
00:03 piesquared So like that/
00:03 MarisaG Yep
00:04 librebob[m] wow i keep typing apps
00:04 librebob[m] for some reason
00:04 librebob[m] i meant mods
00:05 piesquared Didn’t wrk
00:05 piesquared *work
00:05 MarisaG You have the other setup finished?
00:05 piesquared Hm?
00:06 MarisaG And of course the obvious of shutting down and restarting the server?
00:06 piesquared Yes.
00:06 MarisaG the minetest server, not the whole thing
00:06 piesquared Yeah, ik.
00:06 MarisaG Ok just a sec and I will tell you what else to check
00:06 piesquared How does setting up IRC2 with discord work?
00:07 MarisaG You have the luarocks installed?
00:07 MarisaG It doesnt as far as I know
00:07 piesquared Luarocks?
00:08 MarisaG the irc mod needs that
00:08 piesquared Um, not to my knowledge.
00:08 MarisaG what platform are you running on?
00:08 piesquared Linux
00:08 MarisaG Ok, you need these steps before it will work:
00:09 MarisaG # # On Arch Linux: # pacman -S lua51-socket # # On Debian/Ubuntu: # # Debian/Ubuntu's LuaSocket packages are broken, so use LuaRocks. # apt-get install luarocks # luarocks install luasocket
00:09 MarisaG grr let me paste it one at a time:
00:09 piesquared I’m Ubuntu.
00:09 MarisaG Oh makes it easier, let me copy the lines for that:
00:10 MarisaG apt-get install luarocks
00:10 MarisaG then
00:10 MarisaG luarocks install luasocket
00:10 piesquared It doesnt have to be in the MT folder?
00:11 piesquared Also, I’m no in the sudoers file, so if we can do gitclone...
00:11 MarisaG You need to do this to get the irc mod itself:
00:11 MarisaG cd <Mods directory> && git clone --recursive https://github.com/minetest-mods/irc.git
00:11 MarisaG And no, the IRC mode needs luasocket
00:12 MarisaG I dont think you can set it up if you dont have root access at least temporarily
00:12 MarisaG Who is doing your hosting?
00:13 piesquared Mesecrafted01
00:13 MarisaG hmm
00:15 piesquared He is on discord, but i dont have access to discord.  (Dont ask.) (no, I’m not banned)
00:15 MarisaG They can probably set it up for you or at least give you sudo rights for a few minutes
00:16 MarisaG Thats why I let people have root/sudo access on my servers :(
00:16 piesquared You shouldn’t, really.
00:16 MarisaG They are dedicated
00:16 MarisaG Noone else can see them and vide versa
00:18 Scotty_Trees joined #minetest
00:21 piesquared Also, i have a moderator that want translator mod for Russian... do you know any good ones?
00:24 MarisaG Nope, no clue about russian :(
00:30 piesquared Hm.  Any good translators?
00:33 MarisaG maybe spanish, i dont know :/
00:33 AspireMint joined #minetest
00:47 ANAND joined #minetest
00:59 MarisaG Didnt ask today LOL
01:00 MarisaG But is anyone interested in a free Minetest server running on a Ubuntu host with 2GB ram, 50gb SDD, and 1gbps network speed
01:01 MarisaG oh, its a dedicated server, not just a partitoned server with multiple members on the same server
01:03 MarisaG Im looking for friends and like to do a good deed ;)
01:18 piesquared YES
01:18 piesquared I AM
01:18 piesquared My server has crappy internet x 50
01:18 piesquared MarisaG: Let’s talk. ™
01:19 MarisaG Cool!
01:19 MarisaG Can I pm you?
01:22 MarisaG hmm :(
01:24 piesquared joined #minetest
01:24 piesquared Yes, you can
01:25 piesquared And, i am new to this, so, you may have to explain how to get the server stuff from my server to yours... wait... it just started, ill redo it. XD
01:25 MarisaG ok
01:25 MarisaG good idea :)

07:01 Quiark Not sure if close enough but soil did form there
07:05 Alexand{er|ra} joined #minetest
07:06 ChimneySwift definitely wet soil? if that's not it it might be because they don't grow while the chunks are unloaded, try standing around for a bit
07:06 ChimneySwift also they need light to grow if it's underground

15:47 fasm Hi
15:47 fasm Are there any explosion proof materials?
15:47 twoelk clouds
15:48 twoelk not in inventory though iirc
15:48 fasm only clouds?
15:48 fasm i'm trying uunbreakable mossycobble from maptools
15:49 fasm it's not very unbreakable
15:49 twoelk there might be the old admins tools mod
15:49 twoelk and the one ore other mod adding bedrock
15:52 fasm twoelk: just tried it, cloud blew right up
15:52 twoelk :-(
15:54 fasm https://wiki.minetest.net/Category:Explosion-proof hm
15:54 fasm dont fancy using any of these for building :P
15:55 nowhere_man joined #minetest
15:55 twoelk ah yes, explosions should respect protection
15:56 ANAND joined #minetest
15:56 fasm it's kind of a ffa private world with looting
15:57 twoelk you would have to start your singleplayer map in server mode and then join with a second client
15:57 fasm it's not a singleplayer map
15:57 fasm it's a server
15:57 twoelk ah
15:57 fasm but i'm not too keen on using protection
15:58 fasm kind of defeats the point of my game if there's no risk
15:58 fasm of course i could protect 6 areas immediately around
15:58 fasm unless it would explode through the wall, leaving it intact, which i guess it probably will
15:59 rdococ how would I stretch a 2:1 texture over one node face?

16:53 rdococ hmm, interesting
16:53 rdococ well, I decided to use two nodes

18:26 Alexand{er|ra} I'm going to try to section off parts of the map to create "alternate dimensions". Is it possible to use different C++ map generators on different sections of the map, such as v5 in one area and v7 in another?
18:27 Alexand{er|ra} I'm guessing it's not possible.
18:28 Alexand{er|ra} I'm guessing I'm going to need to use singlenode and learn how to build map generators from scratch in Lua.
18:28 Alexand{er|ra} It'd be awesome if I'm wrong though.

19:47 paramat joined #minetest
19:48 paramat Alexand{er|ra} "Is it possible to use different C++ map generators on different sections of the map" not possible
19:52 Krock ^ not with an engine modification
19:52 Alexand{er|ra} paramat: Drats. That's what I figured, but it never hurts to check.
19:53 Alexand{er|ra} I guess I've got to learn how to use noise and such to create decent terrain from scratch.
19:54 Krock -> LuaJIT + Lua Mapgen
19:56 Alexand{er|ra} "Lua mapgen" is learning to do it from scratch as I said. As for LuaJIT, if I understand what it is correctly, I can't make it a dependency of my project. Some will use it, some won't.
19:57 Krock Those who don't will surely suffer
19:58 Alexand{er|ra} Joy.
19:58 Alexand{er|ra} Maybe I should do something simple and mostly flat then.
19:59 Alexand{er|ra} Hopefully that can be relatively fast for everyone.
20:02 piesquared joined #minetest
20:03 Krock no matter how complicated it'll be. iterating through the mapblock will take you some time (>= 50ms)
20:03 Krock s/mapblock/mapgen chunk
20:05 Krock funny though that the current method is faster than passing the VManip data from C++ directly to LuaJIT using FFI
20:06 Krock data[vi]  vs data[vi].param0
20:08 piesquared Krock, can you make a separated version of the wold anchor in technic?
20:08 Krock wah
20:08 piesquared One that will run without technic.
20:09 piesquared World anchor.  For my server.
20:09 piesquared I dont want technic, but I want that. :ap
20:09 piesquared *:P
20:09 Alexand{er|ra} Slow either way then. Lovely. And if I recall, LuaJIT isn't used in official Minetest for a reason, so relying on users to have it seems like a bad idea.
20:10 Alexand{er|ra} Maybe I should give up on alternate dimensions.
20:10 Krock no idea how that world anchor works but the code seems quite portable. https://github.com/minetest-mods/technic/blob/master/technic/machines/other/anchor.lua
20:11 Alexand{er|ra} It'll be nice if/when Minetest actually supports multiple dimensions via separate map files.
20:11 Krock >  And if I recall, LuaJIT isn't used in official Minetest for a reason,
20:11 Krock https://github.com/minetest/minetest/blob/master/cmake/Modules/FindLua.cmake#L4
20:12 piesquared So, I could put that in my mods folder and have WO?
20:12 Krock WO = ?
20:12 piesquared World anchor.
20:12 piesquared (Honestly...)
20:13 Krock Yeah, new mod and then try&error loading it
20:13 Krock maybe check for dependencies and whether there are technic functions called
20:14 piesquared Yknow, someone should just make a forceloader.
20:14 Alexand{er|ra} Wait ... So LuaJIT is in Minetest but disabled by default? That's really strange.
20:14 Krock Alexand{er|ra}: did you even read that line?
20:14 piesquared Makes it load the blocks within  x y z
20:14 Alexand{er|ra} So are there any disadvantages to enabling it?
20:15 Alexand{er|ra} Krock: Oops, not well enough, it seems.
20:15 Alexand{er|ra} I glanced.
20:15 paramat lua mapgens without luajit are not particularly slow
20:15 paramat but each mapchunk will take maybe 500ms to generate
20:15 Krock paramat: they're horribly slow, especially on nested loops
20:16 Krock table indexing might also take some more time, but I'm not sure about that point
20:16 paramat so you get some server lags that can be a problem for multiplayer
20:16 Alexand{er|ra} So pretty much anyone that doesn't explicitly disable it will have it available. So why was LuaJIT brought up then? I'm very confused.
20:16 paramat so lua mapgen is borderline unusable on a server
20:17 Krock Alexand{er|ra}: http://luajit.org/performance_x86.html
20:17 paramat luajit often runs out of memory when using a lua mapgen
20:18 paramat alternatively you could pre-generate areas in a world then disable lua mapgen when players are playing
20:19 paramat luajit has a memory usage limitation
20:19 Alexand{er|ra} Okay, so LuaJIT needs to be *disabled* to use a Lua-based map generator due to memory issues?
20:19 paramat possibly
20:20 paramat make sure to use the memory optimisations i explain in the news subforum
20:20 paramat a simple well written lua mapgen can probably work with luajit
20:21 Alexand{er|ra} Yeah, I was going to make sure to check out that topic again.
20:21 Krock never had memory issues while developing my mapgen
20:21 Krock dunno why other mods perform so bad in the memory management there
20:21 Alexand{er|ra} Okay, so I need to optimise and also keep it simple, and *maybe* it'll work. Got it.
20:22 Krock and *most likely* it'll work
20:23 piesquared Oii, the IRC mod has a bug...
20:23 Krock and if you're pushing the limits, then it's quite easy to do some optimizations to reduce the size of a cached table (for example) by saving integers/doubles instead of strings
20:23 Krock or to re-use allocated tables

20:52 piesquared How do i do a search of all files in ssh on ubuntu?
20:53 Krock hackerman version:  tree | grep "filename"
20:53 Krock else, use file -type f
20:53 Krock s/file/find/
20:54 piesquared Thanks.  Lost MT mods on my server
20:55 Krock one does not simply execute sudo rm -rf in a directory
