15:07 calcul0n so it can go down to -30000

18:07 jonadab Of course, if you are seriously dedicated to the game you will construct a spiral staircase from the bottom to the top.
18:08 jonadab NOt sure if there would be enough lava to support making that entirely out of obsidian.  Perhaps not.

18:32 scr267 I keep running into this bug, I know tenplus1 ran into this some time ago... does anyone know of a solution to this, or at least some way of troubleshooting it?   emerge.cpp:2a3: virtual void* EmergeThread::run(): A fatal error occurred: std::bad_alloc
18:33 Dr-Frankenstone joined #minetest
18:35 sfan5 std::bad_alloc means Minetest ran out of RAM
18:36 scr267 sfan5 oh seriously?
18:36 sfan5 yes
18:36 scr267 hum cool, good point i shall try to increase memory then
18:36 scr267 I thought it was just trying to access some memory portion that didn't belong to it, but I guess that would be a segfault.... or an out of memory :)
18:38 scr267 Man and I thought I was good with servers ... ... ... I'm going to go back into my corner and open up linux for dummies
18:38 scr267 haha jk, thanks for the help sfan5 :)
18:42 FreeFull joined #minetest
18:43 tomraceror joined #minetest
18:44 HDMI_STECKDOSE joined #minetest
18:47 jonadab Just add a 512 GB swapfile ;-)
18:49 scr267 BWAHAHAA
18:49 HDMI_STECKDOSE mhh?
18:49 scr267 Well, it might be a wee bit slower, but at least it won't be crashing XD
18:49 Dr_Frankenstone joined #minetest
18:51 jonadab Then run some software that has a bad memory leak, until the 512 GB of swap is mostly in use.  Then close the software that has the leak, and immediately sudo swapoff -a
18:51 scr267 hehehehe ouch*** flush the swap to memory
18:52 jonadab Good times.
18:54 Krock downloadmoreram.com
18:54 jonadab I've actually been around long enough to remember the times before the Linux OOM killer was added; if you ran out of swap space, a simple operation like exiting a program could take over an hour to happen.
18:54 Krock jonadab: or just valgrind the bloody thing
18:54 jonadab Krock: Haha.
18:55 Dr-Frankenstone joined #minetest
18:56 Ingar jonadab: in those days, my sysadmin thought me to make sure to 0-terminate C strings
18:57 Ingar I was a bit confused why the shell server would stop responding when I ran my program :D
18:58 Rafi59 joined #minetest
18:58 jonadab Hmm, let's create a swap file on an NFS-mounted filesystem...
19:01 scr267 jonadab: You really like painful experiments :)
19:01 scr267 Run a special docker container which serves a swap file over an NFS
19:02 scr267 I'm sure theres an xkcd about something like that  XD

19:02 jonadab Was NFS still being used by the time Docker came around?
19:02 Ingar scr267: https://xkcd.com/1495/ ?
19:02 jonadab Though I suppose these days we could use zfs.
19:02 scr267 Ingar: Hahahaa nice
19:03 scr267 I wonder if you could cluster an NFS mounted swap file?  active active
19:04 scr267 just to make sure its highly available
19:04 scr267 5 9s
19:04 jonadab With the xkcd approach, it'll probably have nine fives of uptime.
19:04 emacsomancer joined #minetest
19:04 jonadab 55.5555555%
19:05 scr267 LOL after a couple of reboots it might just fail completely
19:05 jonadab I mean, the correct way to automate a periodic reboot is with cron.
19:07 Pie-jacker875 joined #minetest
19:07 Hijiri joined #minetest
19:07 jonadab I used to have a server set to reboot every Thursday morning around 8am.  Because that was my early day (I got in by 8:30), so if anything went wrong with the reboot, I'd already be there and not get a call at home.

20:51 Genshin I am getting really close to completing the Dungeon crawl editor.
20:52 Krock rtalk101: glad you didn't look at the bug tracker yet
20:53 Lone_Wolf Seems like someone spawned in an ice biome again
20:53 Lone_Wolf :clap: for DCE though
20:53 Krock isn't that cool?
20:53 VanessaE rtalk101: welcome :)  be aware that we're a random bunch of nutjobs -- or how did c55 put it originally? :)
20:53 Krock uh. a random VanessaE appeared o//
20:53 VanessaE hi.
20:54 Markow joined #minetest
20:54 Krock although it's an unusual choice of words
20:54 jonadab I originally spawned in an ice biome.  But I eventually relocated to a landmass with grassland and savanna and desert biomes.
20:54 jonadab Took pine saplings with me, though.
20:54 * Lone_Wolf hates cool biomes
20:54 Menche jonadab ;o
20:54 Krock Lone_Wolf: install a snowman mod
20:54 Krock and skiing mod.. as soon that exists
20:54 VanessaE Krock: I'm referencing a phrase that c55 once used on the website to describe the modders and devs, but can't remember how he put it :)
20:55 jonadab Oh, heh, didn't know you were here, Menche.  I thought you played the other game.
20:55 Menche :D
20:55 Menche same
20:55 Krock there is no other game aside Minetest. it's a singularity you cannot escape
20:56 Genshin If anyone wants to see some progress with the dungeon crawl editor, here is a screenshot X) https://media.discordapp.net/attachments/306168088032706561/674161168864247808/Screenshot_at_2020-02-03_23-24-20.png?
20:56 Krock "** DANGER" ...  *villain music starts playing*
20:57 Krock that's a lot of particle spawners
20:58 Genshin I might tone the particles down a bit for some of these NPCs
20:58 Lone_Wolf Wait, you have Discord Genshin?
20:58 Genshin yes
20:58 Lone_Wolf Are you on the UMTD by any chance?
20:59 Krock or add more to increase the boss defeating difficulty. that amount could already cause my computer to drop several frames
20:59 Krock Boss + Stutter vs Lonely Figher
20:59 Genshin Krock, I did worked on a phase feature for bosses, so they do transform along the way
20:59 Dr_Frankenstone joined #minetest
21:00 Krock Genshin: that's impressive. So will there also be a rare skill to dual-wield tools?
21:00 Genshin Lone_Wolf, Unfortunately I'm am not on the UMTD.
21:00 Genshin Krock, I am planning to make a dual wield thing
21:01 Genshin it's tricky, but only works on 3rd person im afraid X)
21:01 Lone_Wolf Ah, ok, I have an invite if you want one
21:01 Krock indeed

21:01 Genshin Sure Lone_Wolf

21:02 Krock where are you

21:02 Krock thanks :)
21:03 LWBot Entity attached to player is only visible in third person camera modes (actually a request, not a bug)
21:03 Dr-Frankenstone joined #minetest
21:04 Krock and attached meshes lagging behind the parent bone is a feature
21:07 Krock btw, attachment positions won't work properly on invisible meshes (1st person player) so you'd unlikely get a nicely attached entity in 1st person view
21:07 Krock that's to destroy some hopes

21:54 Genshin What did you tried to do?
21:57 erlehmann joined #minetest
21:58 catninja joined #minetest
21:59 Dr-Frankenstone joined #minetest
22:00 Genshin or describe the nature of the occurrence
22:00 sfan5 did you search the issue tracker?
22:06 Dr_Frankenstone joined #minetest
22:10 illwieckz_ joined #minetest
22:11 scr267 I found this in the issue tracker so I'm looking through the mods I have: https://github.com/minetest/minetest/issues/7835
22:15 sfan5 that one was fixed in 5.1.x though
22:15 scr267 so I thought... somehow I'm getting a similar error, but I'm not sure that its caused by this issue.
22:15 scr267 I'm on 5.1.1 by the way
22:19 Genshin Could probably be that you were trying to access a field that does not exist
22:20 scr267 could this be the cause? https://paste.centos.org/view/bbf6ab68
22:20 scr267 I found an earlier conversation where sfan5 tells another user not to do that: http://irc.minetest.net/minetest/2019-12-11
22:21 Genshin have you tried using method get_luaentity?
22:21 Genshin that might solve it
22:22 scr267 No, I'm not coding any mod... I'm updating mods that I already have  - and which in those versions work... unfortunately due to the nature of the error, I can't pinpoint which mod is the cause
22:22 scr267 culprit
22:22 scr267 Unfortunately I have to go
22:22 scr267 Ill be back later and I'll try to remove some mods ...  see if I can replicate
22:22 sfan5 that might be your best bet
22:23 sfan5 or go annoy a coredev to implement backtraces for such an error
22:24 Genshin Does remove function remove a entity with a specific userdata?
22:24 Genshin does it require a userdata input?
22:25 sfan5 which function are you referring to?
22:25 Genshin <object userdata>:remove()
22:26 sfan5 should work
22:31 Dr-Frankenstone joined #minetest
22:34 Genshin scr267, try this fix https://pastebin.com/NhtvZSiJ
22:35 Dr_Frankenstone joined #minetest
22:35 Genshin forgot to add double quotes on the strings X)
22:38 Genshin scr267, fixed: https://pastebin.com/RWb4zGLi
22:47 sfan5 that might still break when an object is removed while you iterate
22:48 sfan5 generally you aren't supposed to touch minetest.luaentities anyway
