03:16 asdflkj_sh I'm trying to get paradust's https://minetest.dustlabs.io/ to load from my local filesystem (file:///home/asdf/gr/mt/minetest.dustlabs.io/mt/index.html... I did wget -r https://minetest.dustlabs.io/mt, then manually downloaded https://minetest.dustlabs.io/mt/minetest.data, then https://github.com/paradust7/minetest-wasm/raw/main/static/.htaccess)
03:16 asdflkj_sh I really have no knowledge of browsers, cross origin requests, access control checks, etc., is it possible to modify it to make this work?
03:17 MTDiscord <Jonathon> @paradust ^
03:17 erle asdflkj_sh which browser?
03:17 asdflkj_sh erle: luakit (webkit based)
03:17 erle asdflkj_sh if you have python3 installed, you can use python to get a local webserver that serves a directory
03:18 erle python3 -m http.server 8080
03:18 erle i think
03:18 MTDiscord <paradust> it needs certain headers: https://github.com/paradust7/minetest-wasm/blob/main/static/.htaccess
03:18 erle paradust you only need those for cross-origin access though
03:18 asdflkj_sh actually I'm trying have a working PoC that a friend can run on a Chromebook
03:19 erle so why would they be needed
03:19 erle if you host it locally
03:20 asdflkj_sh they have termux so they can run a web server, but I think it's too sandboxed to be accessed from Chrome
03:22 asdflkj_sh (it's a managed chromebook so it's basically a padded prison cell)
03:22 paradust I believe the cross-origin headers are needed because webassembly w/ pthreads is a security risk for a website with cookies (due to spectre, etc)
03:22 paradust or hosting other private data
03:23 paradust it also needs to be hosted on https, I believe
03:23 paradust (not 100% sure of that)
03:24 asdflkj_sh how feasible would it be to embed the data into the js or html so it wouldn't have to be requested separately?
03:24 paradust embed what data?
03:24 paradust minetest.data ?
03:24 paradust that's generated by the emscripten file packager
03:25 paradust it can be modified, if you're willing to do the work
03:27 paradust erle: https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/SharedArrayBuffer#security_requirements
03:28 erle oh i see
03:29 erle paradust as far as i understand though, webassembly with pthreads is a general security risk then?
03:29 paradust oh certainly. but it is enabled by default :D
03:30 grouinos joined #minetest
03:32 asdflkj_sh I'm willing to work, and capable if it involves, say, pasting a snippet of JS someone provides for me and the base64 encoding of mintest.data into index.html or minetest.js, not capable if it's much more complicated (I don't know JS)
03:32 paradust they must feel confident that separate processes are isolated, but because the webassembly (and even the js) lives in the same process (and even on the same thread, in some cases) as the browser threads, there is no way to mitigate it
03:32 sys4 joined #minetest
03:33 paradust asdflkj_sh: what's your overall goal here?
03:35 asdflkj_sh paradust: to enable my friend to use minetest to learn lua and coding on a managed chromebook that blocks your site
03:36 paradust huh. do you know why it blocks the site?
03:36 paradust why is the .data file a problem?
03:36 paradust you should be able to copy all the files and host it somewhere else (but it needs to be on HTTPS)
03:37 asdflkj_sh it blocks everything not on a whitelist to keep the managing school legally unliable from accidentally letting kids download porn, malware, and whatnot
03:39 asdflkj_sh the whitelist is pretty arbitrary but blocks most small independent sites so if I host it it'll likely still be blocked
03:40 paradust but it lets you run commands from the terminal?
03:41 asdflkj_sh yes, they have a few whitelisted Android apps available, Termux and MineCraft EE being the only two my friend uses
03:43 erle what is in minecraft EE that is not normally in minecraft?
03:43 asdflkj_sh erle: https://en.wikipedia.org/wiki/Minecraft#Minecraft:_Education_Edition
03:45 erle asdflkj_sh just wait until notch implements lua API lmao
03:48 paradust the place to start would be to try to setup a local webserver, and see if it even works
03:48 paradust can you install the netcat tool?
03:50 paradust if you can, run in terminal: nc -v -l 5000
03:50 paradust and then see if you can surf to http://localhost:5000/
03:50 paradust if you can, netcat will spit out some http junk
03:53 asdflkj_sh they're in a different timezone and asleep right now, will ask them to try that though I think it won't work (think we tried something like that in the past but not quite as simple and good a test)
03:55 erle is your friend able to afford an old thinkpad? minetest runs on everything from the last 15 years or so, but you don't get much more than 30 fps on some.
03:55 erle if your friend has the money, it might be a better investment of their time. if not, is jailbreaking the chromebook a possibility?
03:55 erle or would that be detected
03:56 asdflkj_sh great suggestions, unfortunately both fairly unviable

04:20 paradust erle: Looks like Minecraft EE disables network play except for within an "Office 365 tenant"
04:20 erle LOL

15:32 ghoti So.. my xban.db reset a couple of days ago, and new bans have been added since then. I have a backup. Is there an easy way to merge the two files? Or do I need to write something?
15:46 MTDiscord <luatic> How and why did it reset?
15:48 MTDiscord <luatic> Anyways, the "xban.db" files are just Lua scripts that return a Lua table when run. Simply loading both, merging the tables (possibly recursively), then writing should suffice.
15:55 sys4 joined #minetest
16:13 MTDiscord <Jonathon> Xban uses serialize so it loses its mind when it gets to bick
16:13 smolensket Hello. I am trying to install ubuntu 18.04.1 in VMware Workstation 2019.3 on a Mac. I cannot install the bootloader in UEFI mode, because it cannot install it on the Macintosh EFI System Partition (SAP) (/boot/efi). Is there any solution to this?
16:13 MTDiscord <Jonathon> *bug
16:13 smolensket I'm aware of this error message: https://i.imgur.com/6JfPm2d.png
16:13 MTDiscord <Jonathon> Xban should use json like areas, travel etc does to fix the issue
16:14 MTDiscord <Jonathon> However the issue was reported and krock closed it as fixed when it isnt
16:15 MTDiscord <Jonathon> Issue: https://github.com/minetest-mods/xban2/issues/19
16:17 MTDiscord <luatic> wsor: that's what my question was aiming at
16:18 MTDiscord <luatic> and no, Xban shouldn't use JSON
16:18 MTDiscord <luatic> Minetest's JSON API sucks
16:20 sinvet joined #minetest
16:21 sfan5 isn't that just because json itself sucks
16:31 Krock json and its unicode handling sucks
16:31 smolensket Any ideas?
16:32 Krock smolensket: try legacy/MBR boot. that should do the trick. it may be old technology but has proven to be reliable on my side
16:32 smolensket Krock: Thanks. Will try
16:32 Krock dude wtf how are you so far to reply
16:32 Krock s/far/fast/
16:42 MTDiscord <Tuxifan> Krock: Some people can type faster than others 😉
16:44 Krock my message was sent at 1651336349 and I go a reply at 1651336350
16:44 Krock this makes it a solid 180 words per minute even ignoring the reaction and read time
17:06 Verticen joined #minetest
17:22 MTDiscord <Jonathon> Xban should use json unless it wants to keep losing ban lists.
17:23 MTDiscord <Jonathon> Areas, travelnets, already do this because of the issue
17:27 grouinos joined #minetest
17:34 MTDiscord <Warr1024> IIRC mod_storage is now actually database-backed, so isn't it becoming more practical now to just store your data in one of those, broken up into separate keys?
17:39 MTDiscord <Tuxifan> Krock: https://paste.centos.org/view/31b54b06
17:40 MTDiscord <Tuxifan> It was a bot
17:40 Krock it works pretty good tbf
17:42 MTDiscord <Warr1024> Clever
17:42 MTDiscord <ROllerozxa> tbh I already thought it was kinda weird someone was asking about installing ubuntu in a VM in #minetest so the fact it was a bot wasn't very surprising :P
17:43 Krock I wonder where the answer went
17:44 Krock nowhere?
17:44 MTDiscord <Warr1024> I could imagine a business angle behind using chatbots to harvest expert answers over IRC and other non-obvious sources, to run a stack-overflow-like help site but without just stealing the same SO answers that everybody else scrapes.
17:45 MTDiscord <Warr1024> How many times have you searched a technical question, clicked what looked like an answer, and just got the same not-actually-useful result you already found on SO, but on some different site with half-broken layout?  For me ... too many times indeed.
17:47 jadedctrl jesus, those sites are the worst…
17:58 MTDiscord <GoodClover> there needs to be a collaborative project collecting shit sites like that and removing them from results
18:02 MTDiscord <Warr1024> The harder you wack, the harder they mole.
18:02 ___nick___ joined #minetest
18:03 MTDiscord <Tuxifan> Krock: Into some GPT I guess
18:03 definitelya GoodClover: That implies search engines would care.
18:05 ___nick___ joined #minetest
18:06 MTDiscord <GoodClover> I'm pretty sure most search engines would be happy to remove bad results
18:06 MTDiscord <GoodClover> unless they're super anti-censorship
18:06 MTDiscord <ROllerozxa> they're even worse in other languages. in english they're reasonably comprehensible but in swedish they're just... not even google translate quality, they legit must be using some bargain bin translator service to translate their english content to every other language known to man
18:06 jess joined #minetest
18:08 MTDiscord <Warr1024> tbh, after messing around a bunch with weblate, and having to deal with a bunch of languages that are like half-filled-in, it would be nice to be able to just pull in automatic machine translations for everything and use it as a fallback beneath human-translated stuff...
18:10 definitelya GoodClover: hmm, maybe the FOSS ones, the others would need incentive probably.

18:37 gera joined #minetest
18:38 settl3r[m] how do i "convince" my lava source block to produce (cobble-)stone instead of pumice/basalt?
18:39 gera Hi. I'm new to lua. I want to make a command that takes coordinates, three floats positive or negative like this "-111.5 18 75". How do I parse such string in lua?
18:46 Krock local parts = inputstring:split(" ")
18:46 Krock then use tonumber(parts[1])  for each index
18:47 Krock there's also the minetest.string_to_pos() function which however won't be as easy to integrate into multi-argument chat commands
18:49 gera I came up with this: x, y, z = string.match("111.5 -2 3", "([+-]?%d+%.?%d*) ([+-]?%d+%.?%d*) ([+-]?%d+%.?%d*)")
18:50 gera tonumber might be a better idea,ty
19:00 calcul0n settl3r[m], it's probably the gloopblocks mod which changes lava+water behaviour
19:00 calcul0n so simple answer: disable it :p
19:01 calcul0n or make cobble from basalt, there should be a recipe for that

19:06 v-rob joined #minetest
19:07 appguru joined #minetest
19:15 MTDiscord <luatic> gera: keep in mind tonumber is overly permissive though: it will allow NaNs and inf
19:15 MTDiscord <luatic> as well as hex, exponents etc
19:28 Verticen joined #minetest
19:33 erle luatic that's not overly permissive
19:33 erle luatic gera Krock the correct thing is to first match via a regular expression, then use tonumber
19:34 Krock there's no "correct way". many roads lead to rome
19:34 erle gera if you either use tonumber or use the current player position without checking it, you can run into this bug, so don't https://github.com/minetest/minetest/issues/11742
19:35 erle Krock there is a correct way in terms of “state of the art”. and that is to match the input using a context-free, regular or calc-regular grammar. and to perform full recognition before processing.
19:35 MTDiscord <luatic> erle: no, a regex is only part of the solution
19:35 erle luatic, yeah, but it needs to be the *first* part of the solution
19:35 Krock regex will solve your problems and shoot yourself into the knee
19:35 erle to make sure that tonumber gets no NaN
19:36 erle or -Inf or so
19:36 MTDiscord <luatic> to enforce a simple [+-]?%d+%.?%d+ format
19:36 MTDiscord <luatic> Krock: no
19:36 erle if you want to enforce a format, you need a regex
19:36 MTDiscord <luatic> must be %d*
19:36 erle for a commannd
19:36 MTDiscord <luatic> Lua patterns are easy to write
19:36 erle lua patterns also suck if you write them badly lol
19:36 MTDiscord <luatic> Anyways, you need Lua patterns + range checks here
19:36 MTDiscord <luatic> Yeah, Lua patterns have poor performance characteristics
19:37 erle i believe you can hang mcl5 by inputting 4096 times the letter a in the creative inventory search field
19:37 erle due to backtracking runtime bullshit
20:03 MTDiscord <luatic> bruh what
20:03 MTDiscord <luatic> show me the patterns involved please
20:03 MTDiscord <luatic> but yes, Lua patterns have worst-case exponential runtime
20:04 MTDiscord <luatic> the sad thing is that they probably even have exponential runtime for some simple patterns that a decent regex engine would be able to match in linear time
20:04 MTDiscord <luatic> and yes, I am planning to write my own RegEx engine in pure Lua :P
20:09 erle luatic we fixed it in mineclonia i think, i am not motivated to look it up
20:10 MTDiscord <luatic> hmm okay
