00:12 MinetestBot  02[git] 04rubenwardy -> 03minetest/minetest: Update to Android target SDK 30 (#11746) 1351cfb57 https://git.io/JM3t9 (152021-11-27T00:10:13Z)
03:48 cheapie      New Luacontroller program for people to play with, a sort of outdoor lighting controller thing: https://gist.github.com/cheapie/2039ae3274e7d629adf377b7777520d1
03:50 cheapie      Expects a digistuff advanced touchscreen on the channel "touchscreen", a blinky plant on any pin is recommended, and other channels for optional devices will be mentioned during the hardware setup wizard. Output to the lights is on the digilines channel "light" (for digilines dimmable lights and such) or via mesecons on any pin aside from the one used by the blinky plant.
03:52 cheapie      Supports (in addition to turning the lights on/off manually) control based on light level, in-game time, real-life time, or remotely over the internet by fetching the desired state from a server.
05:40 cheapie      Huh, minetest.net actually renders kinda okay on that web browser someone made in a Luacontroller a few years ago.
05:43 cheapie      ...which then promptly broke when I asked it to render a larger page.
08:07 Chpy0        Im frightened
08:09 definitelya  Chances are, what or who frightens you is scared more than you are. :D
08:09 definitelya  lmao
08:09 Chpy0        are those croopers afraid of me
08:10 Chpy0        maybe they're actually defending their territory that you're stealing
08:10 definitelya  big think
09:55 ebrasca      How to start a server with a subgame with a terminal?
10:40 ROllerozxa   ebrasca: --gameid argument
10:40 ROllerozxa   see the manpage
10:41 ebrasca      I get 'Game "mineclone2" not found'
10:42 ROllerozxa   do you have mineclone2 installed to where the minetest server can find it?
10:45 MTDiscord    <j45> do --gameid list if mineclone2 isnt there, it wouldnt be a valid value for --gameid <game>
10:45 ebrasca      I think yes
10:47 ebrasca      there is MineClone2
10:48 ebrasca      but when I join the game
10:48 ebrasca      it is only void!
11:06 ebrasca      MTDiscord: Thank you I figured the last problem , the world does generate correctly.
11:07 ebrasca      ROllerozxa: thanks!
11:27 ebrasca      Do you have some tips for setting the server settings?
11:39 ebrasca      I am interested where are all the setings I can change documented!
11:59 calcul0n     ebrasca, there's a minetest.conf example in the sources : https://github.com/minetest/minetest/blob/master/minetest.conf.example
12:50 MTDiscord    <j45> lol im j45 not MTDiscord
12:50 ROllerozxa   ok MTDiscord
12:50 MTDiscord    <j45> xD

20:41 definitelya  rip github?
20:41 ROllerozxa   rip github.
20:41 MTDiscord    <j45> github is down D:
20:41 definitelya  ae
20:43 MTDiscord    <Jonathon> Lol
20:44 definitelya  son of a bee
20:50 MTDiscord    <Jonathon> Sfan5 probably pushed to many commits :p
20:51 definitelya  erle what did you DO?
20:52 erlehmann    definitelya when?
20:53 definitelya  github is offline
20:57 celeron55    nice job m$
20:58 definitelya  microbesoft
20:58 celeron55    obviously, www.minetest.net doesn't work either, being hosted on github pages
20:59 ROllerozxa   github pages still works, actually
20:59 ROllerozxa   at least for me. idk, might be cached
20:59 MTDiscord    <Jonathon> Works for me
20:59 celeron55    now it works
20:59 MTDiscord    <j45> GH pages is "experiencing degraded performance"
20:59 ROllerozxa   downloads used to work, now it 500s as well
21:00 definitelya  bruh
21:01 sfan5        at least they didn't break gh pages
21:01 ROllerozxa   prob because github pages is basically just static pages being spread across CDNs
21:01 sfan5        well who knows maybe they're talented enough to also break it
21:02 MTDiscord    <j45> at least they didnt break gh pages yet
21:02 ROllerozxa   hmm for how decentralized git is, github sure is a centralized monolith
21:02 erlehmann    git.minetest.land still works you clowns :D
21:03 ROllerozxa   great let's migrate the entirety of github onto git.minetest.land :)
21:03 definitelya  I reiterate: erle what did you DO??? /s
21:04 sfan5        uh oh github pages is actually broken too
21:04 MTDiscord    <Jonathon> Maybe its a intern again
21:05 ROllerozxa   it's always the interns isn't it
21:05 erlehmann    ROllerozxa, it's a risk spread strategy. if you all host stuff on a lot of small git hosts, then your risk is basically like a house fire. maybe one house burns down, but not all of them will burn at the same time. if you all use one huge centralized platform, the risk is more like an earthquake: either no one gets hit or, rarely, everyone has problems at once.
21:05 MTDiscord    <j45> www.minetest.net is still working for me ?
21:06 sfan5        try https://www.minetest.net/downloads/
21:06 MTDiscord    <j45> spoke too soon i guess
21:16 MTDiscord    <j45> yay gh pages is back
21:41 erlehmann    meanwhile https://git.minetest.land/user/sign_up
21:43 MTDiscord    <Jonathon> meanwhile
21:43 MTDiscord    <Jonathon> https://cdn.discordapp.com/attachments/749727888659447960/914270130354139206/unknown.png
21:43 MTDiscord    <exe_virus> Yay local git repo
21:43 MTDiscord    <j45> codespaces too now
21:43 MTDiscord    <j45> https://cdn.discordapp.com/attachments/749727888659447960/914270328555986944/unknown.png
21:44 ROllerozxa   what is codespaces anyways
21:44 erlehmann    exe_virus TODOs in source >> github issues ;)
21:44 MTDiscord    <Jonathon> todos in sources >> prevent certain people spamming issues
21:45 erlehmann    gosh who would ever do that
21:46 MTDiscord    <Jonathon> oh, idk, probably the same type of person that spams dev irc
21:46 cheapie      BuckarooBanzai: Well, since GitHub is having... problems, this is the reply to your comment that I was in the process of typing at the time: https://cheapiesystems.com/media/lightcontroller-comment.txt
21:46 erlehmann    i did actually want to make an issue about clearing up all the boundary issues and offering to do it
21:46 MTDiscord    <luatic> I like having TODO in sources :D
21:46 cheapie      BuckarooBanzai: Also a copy of the code itself is here: https://cheapiesystems.com/media/lightcontroller2.lua
21:47 MTDiscord    <luatic> Minetest has a couple TODOs in it's sources too
21:47 cheapie      Also I'm much easier to get a hold of here anyway, I don't pay attention all that much to GH stuff.
21:48 erlehmann    the recent bitop thing with the two's complement ub error, what is the story behind that?
21:48 MTDiscord    <luatic> The neat thing about TODO comments in code is that they already have proper context. They are also independent of the repo hosting used.
21:48 MTDiscord    <luatic> Where is there an UB?
21:48 MTDiscord    <luatic> The Lua bitop lib is a fairly standard one, it should have no issues.
21:48 erlehmann    there is a comment in the source, wait for it
21:49 erlehmann    oh maybe it was implementation defined
21:49 MTDiscord    <luatic> In fact it is LuaJIT's: https://bitop.luajit.org/
21:49 MTDiscord    <luatic> So if you were running LuaJIT - which you probably were, unless you didn't care about performance - you already had that module.
21:49 erlehmann    uh i run builtin lua
21:50 erlehmann    but also i do not do bitwise ops
21:50 erlehmann    i can show you the shameful thing i did
21:50 erlehmann    for the colors
21:51 MTDiscord    <luatic> show it
21:53 erlehmann    so i want to have ARRRRRGGGGGBBBBB bits, converted from 24bit RGB
21:53 definitelya  yes show it! xD
21:53 definitelya  I'm out
21:54 MTDiscord    <luatic> only a single alpha bit?
21:54 MTDiscord    <luatic> RIP semitransparency
21:54 MTDiscord    <luatic> not that it every lived within MT
21:54 * cheapie    looks over at the mess that is https://cheapiesystems.com/git/digistuff/tree/gpu.lua#n38 , speaking of colors
21:54 cheapie      ...or, well, the whole file, really.
21:55 erlehmann    +					colorword = 32768 +
21:55 erlehmann    +						((math.floor((previous_r * max_sample_out / max_sample_in) + 0.5)) * 1024) +
21:55 erlehmann    +						((math.floor((previous_g * max_sample_out / max_sample_in) + 0.5)) * 32) +
21:55 erlehmann    +						((math.floor((previous_b * max_sample_out / max_sample_in) + 0.5)) * 1)
21:55 erlehmann    basically that luatic
21:55 MTDiscord    <luatic> 32768 -> should be 0x...........
21:55 erlehmann    uh what
21:55 MTDiscord    <luatic> use hex notation
21:55 erlehmann    did i botch it
21:55 MTDiscord    <luatic> more readable
21:55 MTDiscord    <luatic> did you?
21:56 erlehmann    absolutely not
21:56 erlehmann    it kinda works
21:56 MTDiscord    <luatic> I'd use 2^5, 2^10 etc instead of hardcoding the numbers; I'd also have a function do the depth rescaling
21:56 MTDiscord    <luatic> I mean, those numbers are "hard" either way xD
21:57 MTDiscord    <luatic> But 2^x shows the intention, shifting something by 5 bits
21:57 MTDiscord    <luatic> otherwise I have to calculate log2(num) to find out by what you're shifting
21:57 erlehmann    well, then i'd have to use math.pow inline?
21:57 erlehmann    which is a function call
21:57 MTDiscord    <luatic> No
21:57 erlehmann    ok show how
21:57 MTDiscord    <luatic> Lua has a^b syntax
21:57 MTDiscord    <luatic> You can just use it that way
21:57 erlehmann    oh i did not know
21:58 erlehmann    ; lua

22:00 MTDiscord    <luatic> OFC erlehmann is trying to break it now
22:01 sfan5        I am positive it is not breakable
22:01 MTDiscord    <luatic> It has a timeout set? Memory limit?
22:01 erlehmann    sfan5, show source
22:01 MTDiscord    <luatic> What about Python / library bugs?
22:01 MTDiscord    <luatic> You can never be sure that it isn't breakable

22:02 MTDiscord    <luatic> The timeout is there
22:02 erlehmann    python standard library is funny bc broken

22:03 MTDiscord    <luatic> wow
22:03 sfan5        that only gets you anything if it has effects other than raising a memory error
22:03 erlehmann    i think everyone here knows that “V=m=g=” is not valid base64
22:04 erlehmann    (this is what you get if you do not validate your inputs)
22:04 MTDiscord    <luatic> MT's base64 is officially superior to Python's

22:20 Krock        erlehmann: MTB also works in /query
22:21 erlehmann    Krock, thanks, but i lost motivation. i just wanted to figure out if it is *easily* breakable.
22:21 erlehmann    i have some PR to do
22:21 Krock        you're kinda late for that tho. MTB already exists for a long time and should be pretty robus
22:22 erlehmann    Krock as robust as minetest itself? ;)
22:22 Krock        I guess
22:23 definitelya  robobust
22:27 erlehmann    Krock, if it is “as robust as minetest”, it's probably easily crashable by someone putting 20 to 30 min of effort into it
22:27 erlehmann    idc though, it's an irc bot
22:28 erlehmann    you only win bragging rights
22:47 DivideByZero Hello folks.  Rcently I started getting this error when trying to run minetest:  2021-11-27 17:44:55: ERROR[Main]: Game [] could not be found.
22:48 sfan5        no games at all installed?
22:48 DivideByZero Doesn't it come with a default game? What happened to that?  I only tried updating and there used to be a game.
22:50 sfan5        depends on how you downloaded/installed it
22:50 DivideByZero using git
22:51 DivideByZero git pull https://github.com/minetest/minetest.git
22:51 DivideByZero I have been updating it with that line
22:52 DivideByZero Previously kept it working and using latest version.
22:52 erlehmann    DivideByZero, do you have devtest game?
22:53 DivideByZero How do I check that? The GUI won't load.
22:53 sfan5        try minetest --version first and see what it says about RUN_IN_PLACE
22:53 DivideByZero ok.. one moment.
22:54 sfan5        you might have to grab https://github.com/minetest/minetest_game too
22:54 DivideByZero Shall I post the results here?
22:54 sfan5        sure
22:54 DivideByZero It's multiline, do you need it all or just the first line?
22:54 sfan5        pastebin all for good measure
22:54 DivideByZero ok
22:56 DivideByZero https://pastebin.com/uP5ntDDR
22:56 sfan5        ok, system-wide installation
22:57 sfan5        do you know if you had a system-wide install before?
22:57 sfan5        but anyway you can  git clone https://github.com/minetest/minetest_game games/minetest_game  and it should work
22:57 DivideByZero Yes, I've been running it this way for over a year now.
22:57 DivideByZero But recently it stopped working, and today is the first day I had time to deal with it.
22:58 DivideByZero Do I do that inside the minetest git folder?
22:58 sfan5        yes
22:59 DivideByZero ok, thank you for the support. I'll do that now, and report back if it worked.
23:03 DivideByZero The games error disapeared but I am getting a different error.
23:03 DivideByZero terminate called after throwing an instance of 'LuaError'
23:03 DivideByZero what():  Runtime error from mod '' in callback run(): /home/rick/minetest/bin/../builtin/async/init.lua:7: attempt to call local 'func' (a string value)
23:11 sfan5        the files on disk mismatch the version of Minetest you are running
23:13 DivideByZero Should I just delete everything and git clone it fresh?
23:22 erlehmann    for the record, i hate the work that the faulty minetest.find_nodes_in_area() bug fix creates so much. it is, again, way too close to the actual map boundaries.
23:23 erlehmann    as said before, i'll make a proposal to fix the map boundary mess in the next few days, with the goal of not introducing any more bugs this time.
23:27 DivideByZero I deleted both minetest and irrlicht and got them both again. Irrlicht was success, but this following command gives an error about irrlicht, though it should be pointing to it..
23:28 DivideByZero cmake . -DRUN_IN_PLACE=FALSE -DIRRLICHT_LIBRARY=$PWD/../irrlicht/lib/Linux/libIrrlichtMt.a -DIRRLICHT_INCLUDE_DIR=$PWD/../irrlicht/include
23:29 DivideByZero IrrlichtMt is required to build the client, but it was not found.
23:31 DivideByZero I confirm both those do exist.
23:31 sfan5        sounds like you haven't built in a while because that way of pointing to irrlicht doesn't work anymore
23:31 DivideByZero That's true.
23:32 DivideByZero What new way should I be using instead?
23:32 sfan5        http://sprunge.us/TDh8lq this'd work
