16:33 lumberJ lol, I'm sure Linus was playing some minetest one day and got inspired :D
16:34 Unarelith joined #minetest-hub
17:38 xerox123 he might even get it out before we do™
17:39 rubenwardy <user> i want convert a map from ARK SURVIVAL EVOLVED to minetest
18:06 sofar wut
18:06 sofar linux-5.0 was released, yes
18:07 sofar (not in clearlinux yet, sorry)

19:02 lumberJ rubenwardy, what are your thoughts on adding a third parameter here to support passing the 'taken' table to crafting.register_on_craft: https://github.com/rubenwardy/crafting/blob/75c9240c295dcaa3fbb058c375fce90706b8e26f/api.lua#L252 ?
19:03 lumberJ as an example use case, I would like a craft that can be done in the player inventory but requires a certain tool in the inventory
19:03 lumberJ by requiring the tool in the recipe, I can use this function to grab the tool, add wear and return it to the inventory
19:11 Megaf sofar, Hi there
19:11 sofar hey
19:11 Megaf I just realized, I bought two ThinkPads last week, now I can finally run Clear Linux
19:12 Megaf one has a third gen i5 and one has a second gen i7
19:12 Megaf isnt that nice?
19:12 * sofar claps
19:12 sofar try the latest live desktop beta to boot
19:12 _Xenon joined #minetest-hub
19:12 sofar there's a "gui" installer that you can use after booting
19:14 Megaf sofar, no EFI support yet!?
19:15 sofar of course it supports EFI
19:15 sofar we only support EFI, lol
19:16 Megaf sofar, http://paste.debian.net/plainh/fa7f5303
19:16 * Sokomine grabs one of megafs thinkpads and runs away with it
19:16 Megaf sofar, so the compatibility checker script is stupid
19:16 sofar Megaf: you are *currently* booted without EFI support
19:17 Megaf I have EFI enable and Im booted in EFI
19:17 Megaf oh well...
19:17 sofar sudo?
19:17 sofar do you have /sys/firmware/efi ?
19:18 sofar Megaf: I'm pretty sure your systems will be EFI
19:18 sofar just try and boot the live beta img
19:18 Megaf will do, its downloading
19:18 sofar what OS are you currently running though?
19:18 Megaf Debian Sid
19:19 Megaf Sokomine, not gonna happen
19:19 Megaf and boi, are these laptops amazing
19:19 sofar do you have /sys/firmware/efi ?
19:19 Megaf so pleased I gave my MacBook Pro to my girlfriend
19:19 sofar (that's what the script checks for)
19:19 Megaf ok, maybe this laptop is running in CSM mode
19:20 sofar lolol
19:21 Megaf I will format both laptops again though
19:21 sofar join #clearlinux and chat there :)

20:15 Calinou benrob0329: if you want forums, I'd say using a CMS isn't the best choice
20:15 Calinou look at Discourse instead
20:20 benrob0329 Calinou, I don't specifically want forums, but it was an example of something that might be added in the future

21:20 GreenDimond Alright so how do I do the thing
21:21 GreenDimond to see whats eating up my server performance
21:22 sofar perf top
21:22 GreenDimond I meant the actual minetestserver itself
21:23 GreenDimond to see what functions are taking the most time
21:23 GreenDimond actually
21:24 GreenDimond geez
21:25 GreenDimond sofar: Alright so riddle me this. Machine with 1 core could run with a few players pretty smooth, and at 15 was decently laggy but not unplayably so. I upgraded to 2 vCores, I have 10 players on, and its laggy to the point of not being playable.
21:25 GreenDimond CPU is at absurd usage
21:26 sofar perf top will show you
21:26 sofar and show you whether it's ABM's or other things
21:27 GreenDimond oh as an actual command?
21:27 sofar you can use it to zoom in on binaries and functions
21:28 GreenDimond installed linux-tools-common, got 'perf not found for kernel'
21:29 GreenDimond Guess it needs extra packages
21:29 GreenDimond Please hold while I fail to use my head
21:31 GreenDimond well it errored but still worked?
21:31 GreenDimond whatever
21:31 GreenDimond sofar: Should I sudo perf top?
21:35 GreenDimond alright well I see processes
21:35 GreenDimond > Failed to open /tmp/perf-821.map, continuing without symbols
21:35 GreenDimond makes it real hard to read
21:37 GreenDimond 7-9% is get objects inside radius and 6-8% is mapgen
21:42 Fixer GreenDimond: upgraded cpu has higher clock speed? also per core performance...
21:43 GreenDimond Is that a question or?...
21:43 Fixer question
21:43 Fixer iirc minetest/minecraft depend highly from core performance
21:44 GreenDimond OVH says "From 2GHz" on all tiers
21:44 GreenDimond so I dont know if its higher or not
21:45 Fixer what if they run it on some crap ARM thiny...
21:45 GreenDimond Its intel
21:46 Fixer iirc you can run minetest on 4096 cores megaserver and it will still lag af and use just one cpu more or less %)
21:46 GreenDimond The multiple cores is for mapgen
21:46 GreenDimond each player in a unique area takes up map loading power
21:47 GreenDimond which is why more players means more CPU taken
21:54 GreenDimond alrighty
21:54 GreenDimond htop is handy
21:54 GreenDimond CPU usage seems ok
21:54 GreenDimond I bet its just technic and pipeworks being themselves
21:57 mransom joined #minetest-hub
22:27 sofar GreenDimond: zone in on executable minetestserver and screenshot
22:30 GreenDimond how do I 'zone in'?
22:32 GreenDimond ah
22:32 GreenDimond got it
22:32 sofar when you open perf top it'll show functions from all apps that are running
22:32 sofar just select one and i'll ask you
22:32 sofar after that you only see stuff from that executable, or library
22:33 GreenDimond https://pasteboard.co/I3VeAw7.png
22:34 GreenDimond I need to figure out a new image host
22:34 GreenDimond pasteboard is broke rn
22:34 rubenwardy <3 i.rubenwardy.com
22:34 GreenDimond alright bud I dont have a personal site to host stuff on
