00:00 Fixer ladders go up and then turn right, for sky island, teleporter gets added, after that ladders are removed, should be good
00:00 Fixer will try that
00:01 Fixer thanks, gn

05:25 segfault22 I am gonna make a fork
05:28 segfault22 Minetest can be much better than any other voxel-based game such as minecraft,...
05:33 segfault22 I will make it such that all nodes are one, each node being occupied by volumes of material with any shape - for example, smooth hills and caves.
05:34 segfault22 nodes being all "one" on that they would become just a simple placeholder/host for volumes
05:39 segfault22 Of course this will make fluid dynamics insanely difficult, because volume must be conserved. Making it look right is as simple as the smooth hills/caves problem, but calculating "where the fluid should go" is the big one...
05:41 Hijiri Is there an upper limit on the size of item metadata?
05:43 lambda-11235 joined #minetest
05:45 DMackey- joined #minetest
05:54 segfault22 Ideally there is no limit, because it is assigned to a string value, which may be as large as however much free RAM is available to store it. However, the implementation may be flawed somehow (like the world size limit problem) requiring a limit to prevent error
06:00 segfault22 I don't believe it is flawed, but that is entirely out of faith because I have not tested to find any limit. It is possible that nobody has ever stored a large enough metadata value to cause problems, so you may have to test and find if there is a limit.
06:08 segfault22 Be careful so that you don't allow players any way to cause insanely massive metadata values to be written, because it can cause the server to hang while it is processing. For example, if some player figures out a trick that makes the game try to store >1GB of metadata, all players would drop connection before the server gets halfway through processing all of it

06:27 jin_xi joined #minetest
06:55 segfault22 I may have to wait for THz computing before fluid dynamics can be implemented in that fork I'm gonna make,... who knows maybe it won't be too resource-hogging, other more complicated stuff generally is possible with common GHz processors
06:59 jojoa1997 joined #minetest
07:06 est31 joined #minetest
07:06 segfault22 oh and by the way room-temperature superconductor really does exists, there is a patent http://www.google.com/patents/US20110130292 dude says he soaked a ring-shaped pile of graphene flakes with an alkane hydrocarbon like octane, and it holds a current loop producing a stable magnetic field, which ceases when the loop is broken. Now I have to go get some graphene flake powder and eicosane (wax alkane, less flammable) and make some
07:07 segfault22 Surely they can make a THz processor with that, what would satisfy the huge processing load incurred with volume-conserved fluid dynamics in a modified version of Minetest
07:07 est31 only becuase the patent claims so doesnt mean its actually a room temperature conductor
07:07 est31 it can be a fake
07:08 segfault22 That's true
07:08 est31 It very much reminds me of this great invention: https://www.youtube.com/watch?v=nAseG7z_GQo

07:15 segfault22 joined #minetest
07:17 segfault22 My internet connection slowed to less than a Kbit/s at the same time I said it would be a waste of money to apply for a patent for something fake,... conspiracy! :O
07:18 segfault22 joined #minetest
07:18 edgrey joined #minetest
07:18 est31 no?
07:18 est31 its a good investment
07:19 est31 because the moment somebody finds a way to turn graphene into a room temperature superconductor that dude can get the patent out of the drawer
07:19 est31 and say "i have the patent, so you all must pay me"
07:20 est31 its a bit speculative, but for the patent filer its a good investment
07:20 est31 although it should not have been granted IMO
07:23 segfault22 It's not just graphene though. The claims state there must be a "proton donor" - if some company makes a graphene superconductor without any "proton donor", it would be outside the scope of the (supposedly) fake patent, rendering it useless and the investment wasted.
07:25 segfault22 I guess we'll just have to wait and see what "comes out in the wash", so-to-speak...
07:37 segfault22 I will work primarily on that fork I said about earlier, but I will still find time to test the legitimacy of that supposed invention. Even if it is really real, I don't have the equipment to fabricate micro devices, and graphene powder is too expensive anyways
07:39 segfault22 I can get a tiny amount of graphene flake powder for lab/science application, but not nearly enough to make enough of the (supposed) superconductor as would be required to wind the coils for a single motor...
07:41 segfault22 Learning how to read and write C++ will be having a much greater fruitfulness to effort ratio
07:42 Calinou reading C++ is not hard, just remember that you'll see <> often because the programmer is a fish
07:42 Calinou ><<<(°>
07:42 * Calinou runs
07:44 segfault22 I don't "get it",...
07:45 Calinou it's an ASCII art fish :)
07:45 segfault22 I got that part, just not why I will see <>
07:45 Calinou that's part of C++ syntax

07:49 segfault22 I only see one or the other used as math operators, or the use of both as brackets, but I have not yet seen both angle brackets together with no characters between them

07:52 segfault22 have a good day

16:44 Lost2Day LinuxMint 18 MineTest 0.4.13 installed from the sarah repos.  Creative mode is set in two different places depending on local (minetest) or server (minetestserver) based game.
16:45 Lost2Day When running local minetest /home/user_name/.minetest/w​orlds/world_name/world.mt" with setting "creative_mode = true" turns creative mode on.
16:45 Lost2Day When running minetestserver /etc/minetest/minetest.conf with setting "creative_mode = true" turns creative mode on.

20:39 Megaf so, if anyone cares about KVM vs Xen, I just did a series of tests here
20:40 Megaf same OS and packages versions on two virtual machines
20:40 Megaf one KVM other Xen
20:40 Megaf the KVM is running on a newer CPU
20:40 Megaf Intel(R) Xeon(R) CPU E5-2680 v3 @ 2.50GHz
20:40 Megaf thats the KVM
20:41 Megaf Intel(R) Xeon(R) CPU E5-2680 v2 @ 2.80GHz
20:41 Megaf that's the Xen host
20:41 Megaf Xen beats KVM on all tests I made
20:41 Megaf cpu speed, disk speed, memory bandwidth and network latency
