08:20 independent56 First Screenshots; "I haven't given players flying rights", why are they flying? Second: "Oh, ok" https://imgur.com/a/89uZTx0
08:20 independent56 I love mapgen
08:21 independent56 Oh also, by not using snap and using the default build, i fixed the sound problem
08:29 Fixer joined #minetest
08:51 Oblomov independent56: lol
09:06 Parnikkapore_m independent56: So that's why the server was offline yeaterday...
09:06 independent56 Yes, too many hackers flying and disguising themselves as mapgen :p
09:08 Parnikkapore_m I tried to hack advtrains to give me faster trains yeaterday (it's a single constant in the core + any necessary train updates; cheers to proper software engineering)
09:08 Parnikkapore_m It actually works, somehow
09:09 Parnikkapore_m LZB even searches farther and brakes + stops precisely at the right point
09:09 Parnikkapore_m IIRC this is not recommended unless you want your players to see a bunch of ignore and your server's network bandwidth to explode
09:10 Parnikkapore_m So there's still a place for HSF + Large Track Segments
09:12 Parnikkapore_m ^ re the broken balloon loops: Reminds me of when I worldedited the tracks
09:15 Oksanaa joined #minetest
09:16 independent56 HSF will be built on hacking, just throwing tools at the advtrains core until it is faster.
09:16 independent56 I have yet to continue work on it.
09:16 independent56 But it is a project to be the best mod on the server
09:26 independent56 I'm thinking of having my trains not stop. Before the platform, they go to 1 m/s, open the doors, reach the end, close the doors, and speed up. Is this a good idea?
09:28 independent56 But the LZB searching further makes sense, Germans tend to use a lot of math for their precision enginerring
09:31 independent56 With long platforms, it works quite well
09:36 Parnikkapore_m re trains not stopping: I don't think that will save any more than a couple of seconds
09:37 Parnikkapore_m Faster trains have longer braking distance too
09:41 independent56 I know, but it is being used on the metro
09:42 specing_ joined #minetest
09:43 independent56 It allows the trains to be less worn down as the inital shock of starting is reduces.
09:45 Parnikkapore_m Interesting, can you send me a link?
09:52 independent56 Not really.
09:52 independent56 But i can tell you how it works.
09:52 independent56 It uses ATC tracks
09:53 independent56 B5 <-50m -> B1WOL <- Platform -> OCSM
09:55 independent56 or 100 m if your trains go at 20 m/s
09:55 independent56 But on metros they shpuld go slowr
10:19 independent56 Welp, updating mapserver brings baack the locking error
10:20 independent56 It's either parsing errors or database locking :-/
10:21 independent56 https://pastebin.com/b7ra1D73
10:23 independent56 Oh and also, http://56i.duckdns.org:8080/#!/map/0/10/-256/-2742 does not render correctly. There are East-West tracks, but they won't show
10:33 ___nick___ joined #minetest
10:41 independent56 Ah,now its here
11:02 definitelya joined #minetest
11:16 independent56 joined #minetest
11:23 Volker joined #minetest
11:24 Volker Hi! I want to convert my SQLite3 world to postgres for performance reasions, but when I try to convert the world, it tells me: Failed to modify sqlite3 synchronous mode: database is locked.
11:24 Volker My Server is not running though..
11:24 Volker Does anybody have a clue?
11:24 Volker I am on git master
11:25 definitelya joined #minetest
11:25 Volker SQLite3 database has been locked for 3000 ms - giving up! - see the full log at https://paste.debian.net/hidden/ca8299cf/
11:29 independent56 Is anything else running on the database?
11:29 independent56 Say mapserver?
11:29 independent56 *,
11:30 sobkas joined #minetest
11:30 Volker No
11:31 Volker I also increased the timout to 30s and it still fails ._.
11:31 Oblomov Volker: does lsof of the world file say anything interesting
11:31 definitelya joined #minetest
11:32 Volker Oblomov no, if I do "lsof world" or "lsof minetest", nothing indicates any file use
11:33 Oblomov no idea then
11:34 Volker Hm, maybe if I build the client too? ._.
11:34 Oblomov don't see how that would help
11:34 Volker same
11:34 Oblomov sudo lsof /path/to/world/dir/*
11:35 Oblomov (in my case for example running as user shows nothing, because the server is being hosted as Debian-minetest
11:35 Oblomov )
11:35 Volker nothing
11:35 independent56 Is it realistic that 1 - The ballon loop has it's points permenently set to the side? 2 - Buffer stops are at the end to stop trains, allowing easy expansion? https://i.imgur.com/CElLrc4.png
11:35 Oblomov Volker: permissions? is the user you're using to run the conversion the same that runs the server normally?
11:36 Volker yes
11:36 Oblomov ok I'm out of ideas then sorry
11:36 Volker Still thank you! I'll try to dumb debug a bit then
11:37 Oblomov you could try strace to see what get called and what kind of errors get returned
11:37 Volker It's been a while. is it just appending "strace" at the front?
11:38 Markow joined #minetest
11:38 Volker it is :D
11:39 Volker Huh, I *do* get a bunch of EACCES
11:50 Volker Super confusing - I can set a lock as the user which executes the binary, but the binary does not have permission to lock the file?
11:50 Volker omg wait
11:50 Volker MAC
11:51 Volker I forgot I even set that up ^^""""
11:51 Volker big shock: it works
11:51 Volker thanks Oblomov anyway ^^'
12:08 Talkless joined #minetest
12:14 Oblomov Volker: so what was the issue?
12:15 erlehmann joined #minetest
12:24 proller joined #minetest
12:33 Volker Oblomov I am a bit more confused now. Because I am 100% sure that apparmor did not allow locking that file, but I am confused why the server ran without problems? Because the server has to lock the db too ._.
12:34 Oblomov no idea
12:37 Volker Apparently it doesnt actively lock it while running, maybe it has an automatic lock since it is reading it? Anyway, that's out of scope for me. I know what went wrong and now I have a super speedy server :vroom:
12:37 Volker I might just upstream that apparmor profile too

15:05 independent56 The dev version makes it easy to use //deleteblocks and gives shadows
15:06 independent56 Why did i use snap for so long?
15:09 independent56 joined #minetest
15:09 ROllerozxa death to snap, lol
15:09 independent56 It's useful in some situtations. but really, damn it
15:09 ROllerozxa ubuntu always installs snaps over regular packages right?
15:09 independent56 Why use snap when you can do */1 * * * * sudo apt update in crontab? :p
15:10 independent56 Dunno
15:10 independent56 Ubuntu has a package manager, but unsure of whether it is purely snap or a hybrid
15:11 independent56 And it probably gets snap before apt because of autoupdate
15:23 olliy joined #minetest
15:29 toulene8 joined #minetest
15:38 MTDiscord <luatic> @a fluffy... Dashie? (ROllerozxa) who uses the GUI to install packages anyways?
15:40 ROllerozxa wat
15:43 erlehmann joined #minetest
15:49 independent56 It helps me find cool packages i wouldn't find anywhere
15:50 independent56 snap and apt from the command line are like a grocery store. You know whats there. The GUI is like a charity shop. The selected products are cool and constantly change.
15:51 independent56 *Selected products change, products themseleves remain the same

16:49 luizsab good morning! I forget how to activate minetest in ubuntu server... I already permiss on ufw port 30000, but I got the erro time exceed
16:50 Markow joined #minetest
16:51 luizsab in the conf is setting up to announce server and the bind address to the server
16:53 erlehmann luizsab have you permitted both TCP and UDP traffic?
16:55 Verticen joined #minetest
16:55 Krock Minetest only needs UDP 30000 for outside requests, announces happen on a regular basis from the MT server to the master server and do not require forwards
16:55 Krock different story if HTTP remote media is enabled
16:56 rubenwardy make sure you enable ipv6 in MT if your network has ipv6
16:58 luizsab I didn't mencioned, just ufw allow 30000
16:58 luizsab I'll change
17:02 luizsab in the debug i got the error about bind socket it ask if already in use
17:06 rubenwardy make sure you only run the server once

20:19 rubenwardy kabou: any moderator
20:19 rubenwardy if you want to transfer ownership, then please get Fleckenstein to request it
20:20 kabou mineclone2 has changed maintainer and corastenthtry needs to take fleckenstein's place
20:20 kabou cora is afraid to ask on #minetestlol
20:20 kabou fleckenstein sort of ragequit (not due to cora btw)
20:45 v-rob joined #minetest
20:51 MTDiscord <luatic> "ragequit"? He's still very much reachable and in contact with cora, why are you trying to go over his head?
20:52 MTDiscord <luatic> I'll just ping him over here on Discord. @Fleckenstein please request that ownership of the MCL2 topic be transferred to cora.
21:00 specing joined #minetest
21:03 kabou luatic I'm asking on behalf of cora, she's on #mineclone2 if you want to ask her
21:03 kabou and yes, she confirmed she is in contact with fleckenstein

23:31 Guest3350 i'm trying to find where i can install the `cavestuff` metapackage, but i can't find it except for in other packages
23:31 Gustavo6046 joined #minetest
23:31 Guest3350 where do i get it?
23:32 panwolfram joined #minetest
23:33 MTDiscord <Jonathon> well, your obviously on cdb, what requires it?
23:34 MTDiscord <Jonathon> cavestuff is provided in plantlife modpack
23:35 rubenwardy https://content.minetest.net/metapackages/cavestuff/
23:35 MTDiscord <Jonathon> https://content.minetest.net/packages/VanessaE/plantlife_modpack/
23:35 rubenwardy Provided by > Mods
23:35 rubenwardy lists plantlife, as said
23:37 Guest3350 well, useful to know i guess lol
23:37 Guest3350 it sucks that i have to have an unrelated plant mod to get caves
23:38 Guest3350 well, i guess i mean large, expansive, open-space type caves
23:39 MTDiscord <Jonathon> cavestuff is a terrible name
23:39 MTDiscord <Jonathon> all it does is add those (in my opinion annoying) pebbles all over the place
23:39 MTDiscord <Jonathon> not really even in caves
23:39 MTDiscord <Jonathon> https://github.com/mt-mods/plantlife_modpack/blob/master/cavestuff/mapgen.lua
23:39 Guest3350 oh
23:40 Guest3350 so do i need caverealms or something?
23:40 Guest3350 there's a server i play on that i really miss, that has these giant wide open caves to mine in, that just go on forever
23:41 MTDiscord <Jonathon> most likely caverealms
23:41 MTDiscord <Jonathon> what server?
23:41 MTDiscord <Jonathon> could be dfcaverns, or some other mod, but highly unlikely on a server
23:41 Guest3350 it was wunderweltr
23:41 Guest3350 wunderwelt*
23:41 Guest3350 they only release their modpack thru /mods, which is really annoying
23:42 MTDiscord <Jonathon> they use caverealms
23:42 Guest3350 ah
23:42 Guest3350 thanks
23:42 MTDiscord <Jonathon> most servers send there mods to serverlist
23:42 Guest3350 wunderwelt doesn't though, and i've even asked juri about what mods are used and he doesn't wanna say
23:43 Guest3350 but, any suggestions on mods that go well with technic or technic plus?
23:43 MTDiscord <Jonathon> servers.minetest.net, hover over version, else servers.minetest.net/list if you want it json
23:43 MTDiscord <Jonathon> wunderwelt does as i just looked lol
23:43 Guest3350 oh ok
23:44 MTDiscord <Jonathon> use mt-mods technic(technic plus), minetest-mods technic is basically outdate/obsolete
23:44 MTDiscord <Jonathon> greenxenith has a fork of technic chest you could try out, i rather like its interaction with areas, not something if your playing in singleplayer
23:44 Guest3350 should i switch content repositories?
23:45 MTDiscord <Jonathon> swapping out minetest-mods technic for mt-mods technic, you should have any issues
23:46 MTDiscord <Jonathon> if your also using advance trains with technic, try out https://content.minetest.net/packages/gpcf/technictrain/ kinda neat
23:46 MTDiscord <Jonathon> also digilines (digistuff, etc) if your not using it already
23:46 MTDiscord <Jonathon> https://content.minetest.net/packages/OgelGames/powerbanks/ is useful for dragging power with you
23:48 MTDiscord <Jonathon> digtron if you want to dig huge areas, note it is sorta buggy
23:48 MTDiscord <Jonathon> can connect it to power as to not burn fuel all the time
23:49 Guest3350 what mod was it that added the circular saw and multiblocks?
23:50 Guest3350 specifically super glow glass, and super glow glass slabs
23:50 Guest3350 moreblocks, right?
23:51 MTDiscord <Jonathon> yes
23:52 MTDiscord <Jonathon> invsaw if you want the ability to have the saw in your inventory
