00:42 Izzy cheapie: fwiw I get the same worldgen stalls on a dual processor PPC64 box. sometimes it doesn't seem to get there at all.
00:43 pgimeno cheapie: LJ emits SSE2 code, that's probably why it doesn't work on an MMX machine
00:44 pgimeno that applies to JIT-compiled code, not sure about the interpreter but it could be the same case; if not, disabling JIT could be an option (LJ is faster than PUC interpreting too)

01:08 MTDiscord <mistere_123> test
01:09 MTDiscord <jordan4ibanez> no testing in the irc
01:10 ___nick___ joined #luanti
01:10 MTDiscord <mistere_123> I'm switching matterbridge servers, so testing is rather necessary
01:11 MTDiscord <jordan4ibanez> gasp
01:11 MTDiscord <jordan4ibanez> carry on then
01:11 MTDiscord <jordan4ibanez> but I'll be watching :squint:
01:12 [MatrxMT]_ <MisterE> as I maintain the chatbridge between matrix (this is also a test).
01:12 MTDiscord <jordan4ibanez> to make sure the test goes well :D
01:12 MTDiscord <jordan4ibanez> And it seems that it did
01:12 MTDiscord <mistere_123> no one quick test in the dev and we're good
01:12 MTDiscord <jordan4ibanez> you beat me :devtest:
01:12 [MatrxMT]_ <MisterE> all done
01:13 user333_ speaking of i should test something involving one of the bridges
01:13 ___nick___ joined #luanti
01:13 MTDiscord <jordan4ibanez> What is the weight capacity of that bridge?
01:14 MTDiscord <mistere_123> We have discovered it in the past, resulting in the kicking of the bridge from liberaIRC
01:14 MTDiscord <mistere_123> Lets not repeat that
01:14 MTDiscord <jordan4ibanez> What exactly happened?
01:15 MTDiscord <mistere_123> Something about too many messages being ratelimited. I think some setting was changed on sfan5's IRC side
01:16 user333_ yeah libera's bots (ozone in particular) don't get too happy
01:16 MTDiscord <jordan4ibanez> Wow I didn't even know they rate limited the irc
01:17 MTDiscord <jordan4ibanez> Now I wonder if you could transmit an xorg desktop via ssh via compressed characters
01:18 MTDiscord <mistere_123> quintessential Jordan thing to say. Keep it up!
01:30 cheapie jordan4ibanez: Going by my experience on pissnet back in the day....... yes, yes you can
01:32 MTDiscord <jordan4ibanez> I can't even begin to fathom the archaic nature of what displays in the virtual xorg window
01:36 _10KBps joined #luanti
01:36 cheapie jordan4ibanez: Also this reminds me, I'm running out of bad ideas, got any more I can try?
01:36 * cheapie also gives user333_ a '7z b' score of... about 200
01:37 * user333_ runs cheapie through level 9 xz compression
01:37 cheapie Might take a while if you want to do it on this thing
01:38 user333_ xz takes forever but i use it for almost everything
01:38 cheapie I usually use lrzip these days, takes even more forever but compresses notably better
01:38 cheapie Specifically I use it in ZPAQ (-z) mode
01:38 user333_ zstd --ultra -22 is also nice
01:39 cheapie lrzip -zp16 some-100GB-file.tar is very much a "come back in several hours" sort of task
01:40 MTDiscord <jordan4ibanez> cheapie: a lua vm written in lua
01:41 cheapie jordan4ibanez: Does it have to be direct, or can I stick another level in there by getting Lua code running in RVController?
01:41 MTDiscord <jordan4ibanez> yeah! that sounds horrific!
01:42 user333_ lua in linux on rvcontroller on luanti?
01:42 cheapie One of these days I need to get M-mode and U-mode implemented, then maybe I can see about getting Linux running in it
01:43 erbium joined #luanti
01:43 user333_ xz tends to OOM my devices (notably my RPi1) which is annoying because it kills my other znc
01:43 user333_ which speaking of i just had to fix again
01:43 * cheapie gives user333_ a copy of cmix
01:44 cheapie Takes like 20GB of RAM and needs an hour or two per MB, but it compresses better than basically anything else
01:44 * user333_ has not heard of cmix
01:44 user333_ sounds fun
01:44 cheapie https://www.byronknoll.com/cmix.html
01:44 user333_ good use for my 64gb ddr4
01:46 cheapie About the only case where I can actually see it being /useful/ is if you needed to transfer files to some box somewhere that was rather powerful but connected only via dialup
01:47 user333_ or very, very long time archival
01:47 cheapie Ehh, cmix doesn't seem really all that maintained lately, I wouldn't count on it working on a modern system a decade or two from now
01:48 user333_ had to do a bit of work for it to compile on my arch system so probably
01:48 cheapie That and I'm not really sure in what sort of case you would want to archive a few hundred MB (it's pretty much completely impractical for anything more than that) and yet be short on space to do it

02:11 user333_ cheapie, i am using this risc-v emulator in my project: https://github.com/ZakChrom/riscv-emulator
02:11 user333_ thought you might want to see
02:12 crazylad wow look at the colorful language used in the commit messages
02:12 crazylad XD
02:12 user333_ looks like mine
02:12 user333_ not really
02:13 user333_ mine are vague like "fix" or "Update README.md"
02:23 [MatrxMT]_ <the4spaceconstants> what happened to the room name
02:23 [MatrxMT]_ <the4spaceconstants> it's now x and n others
02:24 Sheriff_U3 This is still #luanti ... but I'm not on matrix right now either.
02:49 [MatrxMT]_ <user333> test
02:49 user333_ test passes
02:50 [MatrxMT]_ <user333> fail2ban was the culprit for my matrix server not working, apparently it banned myself
02:51 Sheriff_U3 Hey at least it worked.
02:51 Sheriff_U3 🤣
02:52 [MatrxMT]_ <user333> selfhosting is (mostly) fun

11:13 [MatrxMT] <birdlover32767> i think i have pressed ctrl+esc 5 times today
11:14 [MatrxMT] <birdlover32767> all of them accidental
11:14 [MatrxMT] <birdlover32767> finally got rid of it
11:15 turtleman joined #luanti
11:15 [MatrxMT] <Blockhead256> how do you do that accidentally??
11:15 [MatrxMT] <birdlover32767> my hand is on the left of the keyboard
11:15 [MatrxMT] <birdlover32767> and when i press esc i also sometimes press ctrl
11:16 [MatrxMT] <Blockhead256> is this a laptop keyboard?
11:16 [MatrxMT] <birdlover32767> external
11:17 [MatrxMT] <birdlover32767> i think delete+esc would be better since you need 2 hands for it to work
11:18 [MatrxMT] <Blockhead256> well I can relate with something similar, sometimes I go to remove a usb device from my pc case and accidentally push the power button
11:22 Ingar my cat managed to CTRL-ALT-DEL me once by jumping on the keyboard

15:10 [MatrxMT] <the4spaceconstants> did 5.17.0 come with optimizations?
15:11 Sompi joined #luanti
15:33 crazylad joined #luanti
15:34 crazylad the4spaceconstants: the only optimization I can remember in 5.17 at the moment is with inventory slots, but you can see all the optimization PRs in 5.17 here -> https://github.com/luanti-org/luanti/pulls?q=is%3Apr+is%3Amerged+merged%3A%3E2026-05-08+sort%3Aupdated-desc+label%3APerformance
15:38 greeter joined #luanti
15:39 [MatrxMT] <the4spaceconstants> nice
15:47 sfan5 personally I added some optimizations to make the load time (joining a server) faster, in particular when you have many/large textures or intensive use of texture modifiers
15:49 crazylad \o/
15:51 potter joined #luanti
15:58 [MatrxMT] <the4spaceconstants> I'm asking because I noticed a significant performance increase

15:59 [MatrxMT] <the4spaceconstants> ok edits are not how I expected them to be from the matrix side

18:09 [MatrxMT] <Oktay> Nice prs. Will the volumetric lighting thingy come in 5.17.x or .18?
18:10 crazylad it's currently in 5.18.0-dev
18:11 Krock depends what exact thingy you mean
18:12 Krock there was an optimization but the Visuals Vol 2 PR will need separating.
18:13 crazylad I assumed "volumetric lighting thingy" meant #17360
18:13 ShadowBot https://github.com/luanti-org/luanti/issues/17360 -- Improve volumetric lighting performance by ubuntuyou
18:33 mmuller joined #luanti
18:39 [MatrxMT] <Oktay> Yes, #17360. I just have a laptop with an i5 from 2015 or sth. and those optimizations sound really nice to me.
18:39 ShadowBot https://github.com/luanti-org/luanti/issues/17360 -- Improve volumetric lighting performance by ubuntuyou
18:41 [MatrxMT] <Oktay> In that sense I'm wondering what happens on my machine when the visuals prs arrive. Hope it will work.
18:46 Krock At least I can tell that Linux/Mesa3D performs a whole lot better on old Intel iGPUs (e.g. HD 4000) than Windows 10
18:47 Krock could've tested the PR there too but well.. I guess it works.
18:47 Krock s/works./works just fine there too./
19:08 mrkubax10 joined #luanti
19:15 [MatrxMT] <Oktay> I'm on Fedora.🙂 I'm just afk, otherwise I could copy pasta some specifics.
19:15 [MatrxMT] <Oktay> It's really funny that Linux is getting faster with every release...
19:20 [MatrxMT] <Oktay> You are all doing great work. Reading all those prs etc. let's me look like a child waiting the xmas presents finally to arrive 😅

21:03 im-poke Just wanted to say the discord invite link is broken, and I don't see a contact page on the website
21:10 MTDiscord <rollerozxa> which invite link are you using? discord.gg/minetest should work
21:11 MTDiscord <wsor4035> also, what website: https://www.luanti.org/en/get-involved/
21:11 celeron55 joined #luanti
21:11 im-poke I used the one on the website, yeah
21:12 im-poke Tried the one you posted as well, and doesn't let me
21:12 MTDiscord <rollerozxa> keep in mind that if you are banned, discord might give you a vague error about the link not being functional 🙂
21:12 MTDiscord <wsor4035> or your account is supremely new and you tripped protections
21:12 im-poke I've never been in the server before, and I've been on discord since '17 or so
21:13 im-poke Hold up, I might've been banned years ago for like, getting hacked or something
21:14 MTDiscord <wsor4035> lol, there it is
21:14 ___nick___ joined #luanti
21:14 im-poke (sigh) great, now I need to get a hold of a Luanti discord mod somehow
21:14 MTDiscord <wsor4035> vanishes
21:14 im-poke Any way I can do that?
21:15 MTDiscord <wsor4035> your talking to one
21:15 MTDiscord <wsor4035> fortunately or unfortunately, take your pick
21:15 im-poke Eyy, happy to hear that
21:15 im-poke Could I add you on discord perhaps so we can talk privately?
21:16 MTDiscord <wsor4035> sure, or pm wsor4035 on irc
21:17 im-poke sent you a friend request, last time I used IRC I was 14 so yeah
21:23 im-poke Right, should be resolved, have a good one
