00:27 NathanS21 luizsab: not sure if you seen this. https://youtu.be/yN0xQsOnEok
00:27 NathanS21 Just some shameless self promotion of my Technic video.
00:30 luizsab NathanS21, thank you, I will see
00:36 awell Yes, I remember that video.
00:36 awell I lost a $5 bet because of that video.

02:02 awell minetestvids, no worries. I had a bet with my brother for the optimum height of the solar panels to get max power output. Don't feel bad, I was just being stubborn and my brother remembered correctly.
02:02 awell I was so sure of myself too. Oh well.
02:03 awell minetestvids,
02:03 awell woops
02:06 awell Either way, it is a pleasant memory, even though I lost $5. Keep doing what you are doing. Good night.

07:54 YuGiOhJCJ hello, my server is not listed at https://www.minetest.net/servers/ and I can read in the log "2019-09-02 03:50:49: ERROR[CurlFetch]: servers.minetest.net/announce not found (Couldn't resolve host name) (response code 0)" 3 times, 5 minutes between each message, what is a code response 0 please?
07:56 YuGiOhJCJ I think I just lost the connection at 03:50:00
07:56 YuGiOhJCJ but now the connection is back again and I still don't see my server listed
07:56 YuGiOhJCJ it's just like it is not announced
07:57 YuGiOhJCJ address: yugiohjcj.tk, port: 30000 (UDP)
08:10 fruitsnack hey guys, raycast actually makes the server emerge blocks?
08:10 fruitsnack or only load
08:30 BuckarooBanzai YuGiOhJCJ: does the error still appear in the logs?
08:31 YuGiOhJCJ nope it's the last error seen
08:31 YuGiOhJCJ and now my time is 2019-09-02 10:30:00
08:31 YuGiOhJCJ but the problem is that the server is never listed at  https://www.minetest.net/servers/ and I don't know why
08:32 BuckarooBanzai YuGiOhJCJ: ipv6?
08:33 YuGiOhJCJ no I am using IPV4 as far as I know
08:34 YuGiOhJCJ public and private IP on my server are ipv4
08:35 YuGiOhJCJ sfan5 told me yesterday that he does not see the request whereas I have restarted the server
08:35 YuGiOhJCJ if the request is not received, I understand that my server is not listed at all
08:38 BuckarooBanzai YuGiOhJCJ: can you capture the network traffic with wireshark or something?
08:39 YuGiOhJCJ yes I do not not have a GUI so I can't with wireshark but I can use tcpdump
08:40 BuckarooBanzai YuGiOhJCJ: # tshark -i eth0 "ip.port == 443" (or something like this...)
08:41 BuckarooBanzai YuGiOhJCJ: or can you just do a "curl http://servers.minetest.net/list" and see if the request gets through...?
08:41 YuGiOhJCJ so I will dump traffic with tcpdump on the interface corresponding to my public interface and only packets send or received from 185.107.80.107 (it's the IP of  servers.minetest.net)
08:42 YuGiOhJCJ when I type "curl http://servers.minetest.net/list" I have a huge output
08:43 YuGiOhJCJ probably written in JSON
08:44 YuGiOhJCJ the beginning is: "{"total":{"servers":219,"clients":231},"total_max":[...]"
08:44 ShadowNinja joined #minetest
08:45 BuckarooBanzai YuGiOhJCJ: ok, so not a firewall issue.. :/
08:49 Fusl joined #minetest
08:50 YuGiOhJCJ interesting the request is not sent at all: $ sudo tcpdump -ni eth0 'host 185.107.80.107' does not print anything
08:50 ssieb joined #minetest
08:51 YuGiOhJCJ whereas I restarted the server
08:51 YuGiOhJCJ I expected to see at least one line
08:51 YuGiOhJCJ in the log, I can see: "2019-09-02 10:48:07: ACTION[Server]: Announcing to servers.minetest.net"
08:52 YuGiOhJCJ but it seems that the server is not announcing at all
08:55 YuGiOhJCJ I think that I have no choice but to analyse the Minetest 5.0.1 source code to understand what happens
08:56 YuGiOhJCJ the server is not announcing
09:01 YuGiOhJCJ it's here: https://github.com/minetest/minetest/blob/76325d0ba925cfdd18e387ae96d27921136e98e5/src/serverlist.cpp#L246
09:02 YuGiOhJCJ I will write a short piece of code in C++ that is doing the same thing
09:02 YuGiOhJCJ then I will run it on my server
09:02 YuGiOhJCJ to see if it works
09:13 YuGiOhJCJ hmm Minetest is using a library "jsoncpp" that is built-in the source tree but it is not installed on my system
09:14 YuGiOhJCJ I am wondering maybe it's why it does not work
09:17 YuGiOhJCJ yep, at buildtime it says: "-- Using bundled JSONCPP library." that's why it does not complain at build time, but what happens at runtime? ... I am not sure
09:25 jluc joined #minetest
09:33 YuGiOhJCJ then if  JSONCPP is the one bundled, it will work correctly, I think it is worst to try to use a system-wide JSONCPP, I have to try something else to understand why the announcement is not done
09:33 YuGiOhJCJ I will patch directly the Minetest 5.0.1 source code
09:51 Kimapr joined #minetest
09:54 sfan5 (Couldn't resolve host name) means your DNS is broken, by the way
09:54 sfan5 though then the question is why curl works, but minetest doesn't
10:00 sfan5 ah there is the announce
10:01 sfan5 !up yugiohjcj.tk 30000
10:01 MinetestBot yugiohjcj.tk:30000 seems to be down
10:01 YuGiOhJCJ yes
10:01 YuGiOhJCJ I am working on
10:01 YuGiOhJCJ I have stopped the server
10:01 YuGiOhJCJ and I am running a new one
10:01 YuGiOhJCJ to see if it is able or not
10:02 YuGiOhJCJ to announce
10:02 YuGiOhJCJ correctly
10:02 sfan5 2 minutes ago your server announced but the serverlist got an ICMP udp port 30000 unreachable when trying to connect
10:02 sfan5 3 minutes*
10:02 YuGiOhJCJ sfan5, where have you seen "Couldn't resolve host name" please?
10:03 sfan5 [09:54]  <YuGiOhJCJ> hello, my server is not listed at https://www.minetest.net/servers/ and I can read in the log [...]
10:04 YuGiOhJCJ yes anyway this message happened really when I lost Internet connection :p
10:04 YuGiOhJCJ now it's OK
10:04 YuGiOhJCJ this message has gone
10:05 YuGiOhJCJ yes, in fact 3 minutes ago I ran a server on an other machine but with the address and port
10:08 YuGiOhJCJ ok see my server: http://servers.minetest.net/ :D
10:08 YuGiOhJCJ the announcement is working
10:08 YuGiOhJCJ on this machine
10:09 YuGiOhJCJ weird
10:09 YuGiOhJCJ it's really specific to the other machine
10:09 YuGiOhJCJ maybe a wrong library version
10:10 YuGiOhJCJ I can try to upgrade curl on the other machine
10:10 YuGiOhJCJ to the same version
11:03 Tux[Qyou] joined #minetest
11:14 YuGiOhJCJ how is it possible? I stopped my Minetest server but I still see communications between the serverlist and my server: https://pastebin.com/Psinrpq4
11:15 Milan[m] joined #minetest
11:15 Tux[Qyou] joined #minetest
11:17 sfan5 TCP connections are managed by the kernel and not instantly "gone" as soon as you close the application
11:17 YuGiOhJCJ anyway I have upgraded curl on the server sever to be the same version than the one on the machine where it is working, and it still does not work :\

19:45 Hijiri anyone know whether entities can have animated textures
19:46 Hijiri I noticed snow in minecraft is not particles, but actually just a bunch of planes with a panning texture with snowflakes on it
19:47 comrad joined #minetest
19:50 Krock never seen one tbh

20:14 Hijiri I'm not sure if MC uses the same technique for falling rain (the splash effect on the ground is definitely particles though)

21:55 cheapie Jaysned's old display thing, modernized and now in 3 sizes: https://cheapiesystems.com/media/images/screenshot_20190902_165410.png
21:56 cheapie The middle one is his original size, the right one is his later, smaller one, and the left is double the size (in each direction) as the original.
21:57 cheapie "Cleared", "Full On", "Face", and "Large J" modes on the left are just plain integer-scaled copies of the same images from the middle one, while "Squares", "Blip", and "Snake" run natively at the higher resolution.
21:57 cheapie The middle and right ones are (as far as I can tell) 100% accurate to the original displays they're clones of.
21:59 cheapie All three units are only 1m thick, plus some 1/16th slabs on the back to hide the back side of the screen. The electronics are hidden in the base to the right of the button.
