01:38 MTDiscord <exe_virus> Shout-out to Wuzzy: your doc_modpack is really useful! I've extended it slightly, so now I can just feed it plaintext files to generate documentation (and autogenerated locale/template.txt files) but it works like a charm for full in-game documentation. I might actually create a fully documented game with 80 mods in minetest within a month now, rather than.... never haha. Thank you!

07:05 independent56 please help... wth?!
07:05 independent56 i couldnt possibly disable moreblocks. too many buildings have it as a dependency.
07:06 thmh I've seen this error too
07:08 CWz joined #minetest
07:12 MTDiscord <Callinicus> Howdy folks
07:13 independent56 please help?
07:14 MTDiscord <Callinicus> Could you retrace your steps and perhaps find a conflict? Did you recently install a new mod?
07:15 MTDiscord <Callinicus> I'm no expert on this but that's generally what I can be traced back to. Otherwise if you've an apt for it refer to the debug text document referenced. It may tell you more directly about the issue.
07:16 independent56 ok'
07:18 independent56 50 mb of pure text 0_0
07:19 MTDiscord <Callinicus> Ah okay. Well it says there that panes.lua on line 9 is the culprit, where 'xpanes' is specified. And it doesn't seem to know what that is? You haven't disabled any sort of components within the mod itself? Or did it just randomly occur?
07:20 MTDiscord <Callinicus> If your builds to rely heavily on the panes within moreblocks you could try disabling those specifically and see if you can load up
07:20 MTDiscord <Callinicus> Don't rely*
07:21 MTDiscord <Callinicus> Unless you want to check out the Lua file and tinker a bit. Be sure to make backups of your world and this stuff before trying anything, you don't wanna lose it
07:21 thmh iirc this error just appears randomly, and I could restart the world without issue
07:21 thmh *rarely
07:21 MTDiscord <Callinicus> Hm. As I said I don't know much about Minetest in general. Error messages I understand though lol
07:22 MTDiscord <Callinicus> I'm recently getting into minetest as a platform to host my art
07:22 thmh that's very cool
07:23 MTDiscord <Callinicus> Pretty soon (sometime tomorrow) I'm going to seek out the authors of two particular mods
07:24 MTDiscord <Callinicus> See if they're not opposed to me using their mods to build upon, fix some discrepancies I have with them and add upon what I view as incomplete.
07:24 MTDiscord <Callinicus> I know it's all open source and I'm free to fork if I will but I think speaking to the authors goes a way
07:25 MTDiscord <Callinicus> I'm interested in creating accurate representations of the Roman architectural wonders in Minetest.
07:27 MTDiscord <Callinicus> Kind of a hobby of mine, lol
07:27 MTDiscord <Callinicus> Not Roman architecture but fascination with the Romans in general.
07:29 independent56 hmmm... 99% plagarised.
07:29 independent56 (my yesterday'sworld.mt vs today's)
07:35 MTDiscord <Callinicus> That the Romans syncretized works that came before their own is no secret, but to deny that they had a great part to play in what would become of those works is fallacious. They exhibited a fascination, a pure sense of conservation in the wisdom that of the peoples they savagely conquered, and in the knowledge of past peoples.
07:36 MTDiscord <Callinicus> They committed many misdeeds, but for all the misdeeds they committed they are almost redeemed in that (even counting the body of works destroyed by their own hand) the written records they passed on of these civilizations and peoples has been immortalized... By their conquerors.
07:37 MTDiscord <Callinicus> And we can thank this record for many ideas that have become mainstream today.
07:37 MTDiscord <Callinicus> As well as the continuation of western civilization as we know it.
07:37 MTDiscord <Callinicus> I find beauty in it, that's all.
07:38 TomTom joined #minetest
07:38 thmh yeah the romans definitely improved the state of mankind, art, technology, and wellbeing. hard to argue against that.
07:39 independent56 yay works
07:41 MTDiscord <Callinicus> I think that it's often the case that even those who committed many misdeeds in Rome, as politicians or bankers or what have you believed that they could make the world a better place. Many fought for righteousness in a swamp of villainous characters, some so inclined to malignancy due to the same misfortune.
07:43 independent56 haha worledit tower i made a few days ago

07:43 MTDiscord <Callinicus> Sorry I'm ranting, lol
07:43 independent56 idc, only about artichecture, not society
07:44 MTDiscord <Callinicus> Isn't the fascination in architecture fueled by the sense of mystery that the onlooker experiences when faced with a building? Or the sense of calm, intricacy, even fear that a work inspires
07:45 MTDiscord <Callinicus> I think that has much to do with society.
07:45 MTDiscord <Callinicus> Architecture is art
07:45 MTDiscord <Callinicus> I enjoy art.
07:49 independent56 meh, for me its just "nice minetest world to look at"
07:51 Kimapr joined #minetest

07:59 erlehmann independent56 regarding the xpanes bug, it could be that you have maybe two xpanes mods?
07:59 independent56 hmm
07:59 erlehmann like one out of the modpack
07:59 independent56 its all fixed
07:59 erlehmann another one separately
07:59 erlehmann oh how

08:00 SwissalpS joined #minetest
08:00 MTDiscord <Callinicus> I had an interesting experience earlier today
08:00 ShadowNinja joined #minetest
08:00 MTDiscord <Callinicus> I removed a mod after trying it out on my world, of course I got the unknown node block that I then broke right
08:01 MTDiscord <Callinicus> Well, it left an invisible node right above it that I couldn't remove for the life of me. It acted like a solid block but my cross hair wouldn't highlight it. I had to use /deleteblocks or whatever the command is to get rid of it lol
08:01 MTDiscord <Callinicus> But I did resolve it
08:02 MTDiscord <Callinicus> Ghost nodes are weird
08:03 independent56 use worldedit stick thing and "//set air" next time
08:07 MTDiscord <Callinicus> I actually tried to and it wouldn't work. I had to manually input the coordinates of the node
08:07 MTDiscord <Callinicus> Worldedit thought nothing was there
08:08 MTDiscord <Callinicus> It makes me wonder if after I removed the mod the game freaked out and just turned the space above it into an ignore node.
08:08 MTDiscord <Callinicus> Because worldedit won't remove those as far as I know.
08:11 BigBear joined #minetest
08:14 BigBear Hey folks don't know who looks after this stuff, but just a heads up - dev.minetest.net server certificate needs refreshed from let's encrypt (it expired 25th of may)
08:17 BigBear Also on the forum the sticky/locked topics 'How do i install mods' is pointing to a page that has been removed https://dev.minetest.net/Installing_Mods instead of https://wiki.minetest.net/Installing_Mods
08:24 MTDiscord <Callinicus> I had no idea the Minetest worlds were so small until I played on a server the other day and wound up walking to the edge of the map while looking for an unexplored area lol
08:25 MTDiscord <Callinicus> Took a couple hours but it happened.
08:26 independent56 XD
08:26 independent56 they are'n small.

08:30 independent56 was fun talking.
08:39 nuala2 joined #minetest
08:43 erlehmann is it just me or are users and admins on servers that have money mods a bit hostile to both "hey can you give me stuff" and giving away tons of free stuff?
08:45 nuala2 joined #minetest
08:46 BigBear the earth has a total surface area of 510 million km squared. By default Minetest has a world size of 3844 million km squared if i did my sums right. Perhaps on whatever map someone deliberately reduced the size (it is settable)
08:46 Kimapr joined #minetest
08:48 cheapie BigBear: MT's world is a bit over 60km*60km, so about 3600km² I would think.
08:50 BigBear oh crap yeah i screwed up confuzed m with km
08:58 BigBear its 3844 km2 lol too early in the morning for me, so it is slightly bigger than hong kong.

09:15 Emerald2 Does anyone else find rollback check keeps spamming air -> air to the point you can't actually find out who messed with a node?
09:15 nuala3 joined #minetest
09:17 cheapie I've seen a few air→air entries before, but not at a level that I would call "a lot"
09:17 Emerald2 I get so many, and also from walking light if somebody is carrying a torch, that I often can't get any useful data.
09:18 Emerald2 Because a bunch of people walked over it causing loads of air -> air.
09:19 erlehmann Emerald2 do you have some dynamic lighting mod?
09:19 cheapie Ah... yeah, walking light is... not a great idea, for a few reasons.
09:21 Emerald2 Why's that, cheapie?
09:21 Emerald2 I'm not sure which mod we're using to have the torchlight, it's nice and smooth though.
09:22 cheapie Tends to be rather laggy in multiplayer, most of them tend to be rather buggy, and it's probably the cause of your rollback log spam too.
09:26 nuala4 joined #minetest
09:26 Emerald2 Ahh, we're using illumination.
09:36 Emerald2 Doing some testing I teleported to an unexplored area where nobody has walked. If I jump up and down on a node, it starts the air -> air spam in the rollback check.
09:38 Emerald2 Carrying a torch back and forth on it causes the illumination:light_mid to air and back. Gah.
09:40 cheapie I did suggest ages ago that there be some way to specify that certain set_node() (and similar) calls not be recorded in the rollback log, for this exact reason, but there didn't seem to be much interest and AFAIK it was never implemented.
09:52 Emerald2 Wow, that's sad. They really should implement that.

13:30 Sven_vB hi :)
13:31 Sven_vB How can I make the cart mod tell the MT client that the current trajectory is only valid up to (coordinates of rail turn)? The idea is that in case of lag, the client shall freeze movement at the rail turn until it gets the new trajectory, rather than (seemingly, for a few moments) crash through the wall into the ocean.

14:23 MTDiscord <AntumDeluge> Sorry to be a nag, but the squeaky wheel gets the grease. sfan5, SmallJoker, or rubenwardy, if you could look at my pull request again ( https://github.com/minetest/minetest/pull/11202 ), I think the Action / change needed tag can perhaps be removed now as I made the requested changes.
14:26 MTDiscord <AntumDeluge> IRC/Discord bridge is down. Has the Freenode channel been abandoned?
14:27 MTDiscord <AntumDeluge> Ah, I see the wiki directs to irc.libera.chat now ( https://wiki.minetest.net/IRC ).

16:22 MTDiscord <Callinicus> I suppose to your average player the world size in MT isn't small, but to someone who's used to playing MC anarchy servers where the initial objective  of the player is to get not 30,000 nodes away from spawn but often hundreds of thousands of blocks away, meeting the world border so soon was a big surprise to me lol
16:23 MTDiscord <Callinicus> I did look into the limitations of the engine and now understand why that's the case

17:32 Supersonic hi, does anyone have numbers on how much CPU/RAM/network traffic is required per user on a minetest server for ~700 players or if that's even possible/reasonable?
17:34 specing depends on mods and you aren't getting close to 700 players
17:34 Gustavo6046 joined #minetest
17:35 riff_IRC joined #minetest
17:37 Sven_vB sfan5, should I open a feature request for trajectory validity information?
17:39 Supersonic specing: ok; mods are not yet planned, but if at all, there won't be any heavy ones. Do you mean 700 players are unrealistic for a single server in terms of general performance for the minetest server or in terms of numbers of players that might use it?
17:39 specing Supersonic: both
17:39 specing if you have only most basic and simple mods, you won't get much players at all
17:44 Supersonic ok, sorry, I didn't phrase the question well: we're thinking about doing an university introductory event where people should be able to run around together and solve small riddles
17:49 riff_IRC joined #minetest
18:05 MTDiscord <Warr1024> If you can actually compel roughly 700 people to join an MT server at the same time, that server is probably gonna have a bad time.  I don't know what the exact numbers should be, but if you have the ability to break things up into groups and run multiple independent servers, you might have an easier time of it.
18:06 MTDiscord <Warr1024> You could, say, setup a test server and do your development and testing on it, then load it up with test players to see what its limits are, and then for the actual even, spin up a ton of clones in some cloud service, and then assign each participant to a server or something.
18:14 Supersonic all right, thanks for the estimates, we'll set up a test server and try which resources are necessary :)
18:16 Gustavo6046 joined #minetest
18:24 MTDiscord <Warr1024> One of MT's big scalability limitations is that it can't effectively spread its work out onto an arbitrary number of cores; something like 80% to 90% of its workload (or possibly much more depending on mods) ends up in a single thread.  A lot of independent servers on single-core VMs would probably utilize CPU resources a lot more efficiently than trying to run one world on a big multi-core box.
18:24 MTDiscord <Warr1024> Conversely, though, more instances may be somewhat less RAM-efficient since you're duplicating more basic stuff that could otherwise be shared.
18:25 MTDiscord <Warr1024> Also, the exact level of isolation (VM vs container vs process) may matter, I guess.  It's all a bit of a tricky balancing/tuning act.
18:25 Hawk777 joined #minetest
18:29 MTDiscord <Warr1024> I've only ever run small servers with like 10 players or so myself.  I think there are serious server owners out there who get like an order of magnitude more players, but I'm not sure what it costs them or how much fine-tuning there is to do to handle that many...
18:51 sofar the tuning needed is mods - mods can blow up a server quickly if badly designed or just doing things that are resource intensive
18:51 sofar everything falls down if your mod is not scaling well
