08:01 agaran           Hello
08:01 agaran           anyone knows what happens if I keep node metadata reference (got from get_meta()), inside of some lua code even after mapblock to which node belongs to got evicted from active blocks/from memory?
08:59 agaran           hi Krock
09:00 Krock            hello agaran
09:03 Krock            https://i.imgur.com/RAKrjMH.png
09:17 agaran           lol
09:17 agaran           small progress, now moving too far from mapblock with power-source does not stop lamps from working, yet they don't work too well
13:13 amadin           I can't resize image in formspec more than 16px with ^[resize:<w>x<h> and image file with size more 16px will only 16px in formspec also. Is this normal?
13:22 amadin           Oh i undestand, i can resize by changing second coordinates
13:56 LNJ2GO           Please vote for C++ Irrlicht (and maybe C++ QtQuick): http://www.strawpoll.me/11474009
13:59 Krock            is there now the possibility ofr multi-language opinions?
13:59 Krock            *of
14:00 Krock            perhaps wrong channel, LNJ2GO? I don't get what it's about and how it's related to Minetest
14:00 LNJ2GO           You can vote for multiple options.
14:01 LNJ2GO           The poll is by smb. who make tutorials on YouTube and he asks what should come next.
14:01 LNJ2GO           I would like to learn Irrlicht, so it would be nice if he would make a tutorial about it.
14:02 agaran           well I anyway voted for Irrlicht, just because it will get more attention thus more bugfixes hopefully
14:02 LNJ2GO           And I could better contribute to Minetest :)
14:02 LNJ2GO           +1
14:03 Krock            there are about 11k channels on YT with "smb" in their name

16:03 Fritz01          Hello
16:04 Fritz01          How can i modify the default stack_max value (that's 99) for every single node/craftitem of any subgame?
16:06 Krock            builtin/game/item.lua:641  near "stack_max = 99,"
16:06 Fritz01          Thanks
16:07 Krock            also L604 near stack_max = 99,
16:07 Krock            !next
16:07 MinetestBot      Another satisfied customer. Next!
16:07 Krock            there are further places in the same file, so simply replace all
16:10 Fritz01          Question to everybody: what you think of MultiCraft? isn't it ugly?
16:12 Krock            it's useless
16:16 agaran           Krock: :)
16:26 Fritz01          The shader in minetest are not coded in c++, right?
16:26 Fritz01          shaders*
16:27 est31            nobody codes shaders in c++
16:27 est31            i mean, almost nobody
16:27 est31            maybe with vulkan this will become a thing, but I doubt it
16:28 Fixer            in GLSL iirc
16:28 est31            yes
16:28 Fritz01          so why aren't they coded in java?
16:28 Fixer            examples are in \client\shaders
16:28 est31            Fritz01: because there is no cross gpu java -> gpu compiler
16:29 est31            but there are ones for GLSL
16:29 est31            simple as that
16:29 Fritz01          i don't understand
16:30 Fritz01          you are saying that the java code cannot be compiled togheter with c++ code?
16:30 agaran           java is not compiled.. java is interpreted..
16:30 est31            Fritz01: I'm saying that a shader needs a special compiler, not like a cpu compiler
16:30 agaran           you only squeeze it to bytecode.. which is run on java VM..
16:31 est31            but a GPU compiler
16:31 agaran           and shaders run on GPU
16:31 agaran           thats different world
16:31 est31            and there are tons of GPU models, its far less unified than on CPU world
16:31 est31            the only compilers that exist for GPUs are for GLSL
16:32 est31            and maybe for directx, but good luck porting that over to opencl
16:32 est31            opengl*
16:32 kaeza            but Java is faster than C++
16:32 est31            lo
16:32 est31            l
16:32 Fritz01          sorry for my ignorance but i don't understand what are you talking about
16:32 Fritz01          i can't understand*
16:34 agaran           kaeza: depends on conditions.. but I am not going to dive into that argument..
16:36 Fritz01          shaders are possible to code in java, right? so why it (java) would need a gpu compiler?
16:37 est31            java gets compiled to glsl
16:37 est31            thats all it does
16:37 kaeza            agaran, I'm sorry, I can't hear you over the sound of Java
16:37 Fritz01          but java isn't a compiled language
16:38 waterReflowLives are you a troll?
16:38 Fritz01          me?
16:38 agaran           kaeza: rrright..
16:40 fireglow         Hi, I'm a total Lua noob and I'm trying to write a small mod that sets namecolor on login: http://sprunge.us/OSND But the names are all black. Can somebody tell me what I'm doing wrong?
16:40 Fritz01          fireglow: please post your code
16:41 sfan5            he did
16:41 fireglow         :)
16:41 Fritz01          ops
16:41 sfan5            fireglow: you can replace { get_color_r(color_name), get_color_g(color_name), get_color_b(color_name)  } with colors[name] by the way
16:41 fireglow         ooh
16:41 sfan5            wait no
16:41 sfan5            well partially
16:42 fireglow         will that also get the correct values?
16:42 fireglow         hmm
16:42 sfan5            https://github.com/minetest/minetest/blob/master/doc/lua_api.txt#L1782
16:42 sfan5            see what you're missing?
16:42 sfan5            the r= g= and b=
16:42 fireglow         ooh!
16:42 fireglow         yes!
16:42 fireglow         lol right, thank you
16:42 sfan5            !server firegl
16:42 MinetestBot      sfan5: No results
16:43 sfan5            ¯\_(ツ)_/¯
16:44 Fritz01          back to my question: java doesn't need any compiler. so why can't it be used for the MT shaders?
16:45 sfan5            stop trolling
16:45 sfan5            java needs a compiler
16:45 fireglow         sfan5: thanks, that was it! :)
16:46 Fritz01          nope. it needs an interpreter
16:46 Fritz01          and i'm not trolling
16:46 sfan5            java has a compiler too
16:47 whitephoenix     java compiles to bytecode which runs in a jvm typically but can be compiled
16:47 sfan5            http://docs.oracle.com/javase/7/docs/technotes/tools/windows/javac.html
16:48 Fritz01          so java is a interpreted language that can be laso compiled
16:48 Fritz01          also*
16:48 Fritz01          right?
16:48 whitephoenix     it compiles to bytecode which is interpreted when its run
16:49 Fritz01          bytecode is binary?
16:49 whitephoenix     I guess they easy way to explain it is thats its like binary that only the java virtual machine can read/run
16:50 est31            well yeah
16:50 est31            its like x86
16:50 est31            basically, intel processors are harware interpreters for x86 bytecode
16:50 Fritz01          so java it's a kind of hybrid language (half compiled, half interpreted), right?
16:50 est31            yes
16:50 agaran           est31: you are oversimplifying now..;) there is -lot- more done inside cpu before executing
16:51 agaran           Fritz01: seriously, try to read how all that hardware works, will help you ask right questions..
16:51 Fritz01          agaran: -.-
16:52 agaran           gpu is way different from cpu.. otherwise nobody would make specialized gpus if cpu could do same..
16:52 agaran           in principle yes, all that things can execute code.. so could jaquard knitting machine feed with punched metal strip..
16:53 agaran           it was executing 'program' written by punched holes that translated to knitted pattern
16:53 agaran           but thats more or less all similarity..
16:54 agaran           and hoping for universal language is like hope for universal and perfect glue..
16:54 agaran           someday in far far galaxy maybe.. but not here, not now
16:54 kaeza            most languages are "hybrid"; it's just that you (almost) never see the "compilation" phase
16:54 * whitephoenix   hides the c propoganda
16:55 agaran           whitephoenix: :-)
16:55 Fritz01          wait but the shaders in MC and Terasology aren't coded in java?
16:56 agaran           I don't know MC, but I guess none maybe with exception of some boredom scientist work, of shaders are written in Java..
16:57 agaran           they likely just point engine to right shader code which is binary blob passed to display library which feeds it to gpu
16:57 agaran           anyway, half-afk. lua time
17:00 fireglow         sfan5: got any pointers, or example code, where data (for example: player_name -> color_name) are stored in a db, so I don't have to restart the server to apply changes?
17:05 whitephoenix     https://imgs.xkcd.com/comics/pointers.png
17:05 fireglow         lol
17:23 sfan5            fireglow: nah
17:23 sfan5            you can try looking at the code of e.g. sethome
17:24 fireglow         hmm word
18:13 agaran           anyone observed that on factory_bridges staircases occasionally when trying to move forward from standing in middle of them you first move backwards?
19:09 whitephoenix     I wonder if you could dirtyc0w someone by getting them to install a mod
19:09 whitephoenix     scariest bug in a while
19:10 agaran           from lua? hmm difficult, you can't use fmadvise from lua code directly..
19:10 agaran           it was here for long time..
19:11 agaran           fun, you can fall thru staircase ending in some cases..
19:14 whitephoenix     good thing all red-hat products use outdated kernels :^)
19:14 agaran           ea
19:14 agaran           yea
19:14 whitephoenix     I tried it in a vm, its scarily easy
19:15 whitephoenix     when I have more time I'm going to try to exploit my kindle using it as an experiment
19:21 est31            whitephoenix: minetest mods are not using the os's sandboxing capabilities
19:21 est31            instead, they use the lua VM's
19:21 est31            (if mod security is enabled)
19:21 whitephoenix     mods can write to the world directory
19:21 est31            and the sandbox is quite bad
19:22 whitephoenix     I was thinking 1 curl the binary to the world dir 2 io.popen it or something
19:22 whitephoenix     but I don't know much about how lua works so
19:22 Calinou          isn't os.execute() blocked with mod security?
19:22 Calinou          or Lua equivalent
19:22 est31            yes
19:22 est31            it is
19:22 est31            allowing it would be stupid :)
19:23 est31            idk how dirtycow can be exploited but if its via downloading a binary + making it suid + making it owned by root + executing it
19:23 est31            then its not going to work because executing is not possible in lua
19:23 est31            I'm not even sure whether suid is
19:24 whitephoenix     to run it you just get a binary compiled with -pthread then ./dirtycow file_root_owns.txt "new text"
19:24 whitephoenix     then its just a matter of waiting a few minutes
19:24 est31            mhh
19:24 est31            so your only try then is to overwrite suid binaries
19:25 est31            (or some config files)
19:25 Hawk777          whitephoenix: regardless, curl wouldn’t make the file be SETUID root
19:25 est31            but the world file should contain no root owned files anyway :)
19:25 whitephoenix     Hawk777, it doesn't need to be though
19:25 Hawk777          To dirtycow?
19:25 Hawk777          You write to a SETUID binary.
19:25 Hawk777          Unless you meant to use it to attack the user and not root.
19:26 whitephoenix     oh nvm misread
