08:43 bashboi        Hello
08:44 bashboi        Is possible to install LXC on Android?
08:45 Calinou        bashboi: LXC as in the Linux container thing? how is this Minetest-related? :P
08:45 bashboi        he he sorry, is offtopic I know
09:03 sfan5          lxc requires some container stuff in the kernel as far as I'm aware
09:03 sfan5          android will not hav that enabled
09:03 sfan5          if you want linux on android you can use a chroot
09:05 bashboi        linux on android?
09:10 sfan5          a linux container on android
09:10 bashboi        oh ok
09:11 bashboi        what about this? https://lists.linuxcontainers.org/pipermail/lxc-devel/2013-December/006532.html
09:13 sfan5          it says:
09:13 sfan5          If you want to run those, you'll need an ARM based Android device with a compatible kernel (you'll likely need to hand-build one) [...]
09:13 bashboi        ok got it
09:13 bashboi        thanks
09:18 bashboi        is not possible to enable this "container stuff" as normal android user, right?
09:19 sfan5          the problem is that the functionality does not exist in the kernel
09:19 sfan5          because it was disabled at compile-time
09:20 bashboi        like if the source for that functionalities never existed?
09:20 sfan5          correct
09:24 bashboi        is possible to install a new kernel (on android) while the phone is running?
09:32 bashboi        welcome

13:38 ShadowNinja    Found this online ("Minetest Hack"), anyone in the area interested? (St. Albans, UK; ~1h from London by car) : https://www.meetup.com/Silicon-Abbey/events/240754344/
13:46 iisu           How does MT store the chunks?
13:47 iisu           There's that database where each chunk has a position and a BLOB.
13:47 iisu           I remember reading some piece of documentation somewhere on the forum but it was as blurry as the BLOB itself. :v
13:50 iisu           To store a 16x16x16 nodes of a chunk you would need 16n kiB, where n is the size of data needed to identify the node. But the BLOBs are much smaller than that.
13:53 iisu           BLOBs contain node name strings like "default:mese" also. Why not just give each node an integer ID and store all the names once in a separate array?
13:55 iisu           What magic compression do you use to make them so small despite this seeming inefficiency?
14:11 Jordach        ShadowNinja, impossible - it's within the M25
14:13 ShadowNinja    Jordach: The time?  I just checked Google maps for that and rounded down.  Looks like there's a rail system that will take the time down a lot if the endpoints happen to be close to you.
14:14 Jordach        ShadowNinja, M25 is a nogo for my driver
14:15 CWz            I doubt the legitimacy of minetest hack
14:16 CWz            it could like a terrorist plot to kidnap brits and trade them as slaves to isis
14:16 CWz            it how they brainwash regular people to join their retarded cause.
14:17 ShadowNinja    iisu: Assigning a static ID doesn't make since in modern Minetest for a number of reasons.  For one, what happens if you add a new node, how do you make sure it gets assigned an ID thatis never been used before and won't conflict with any other mods -- and how do you make sure that every other copy of minetest agrees so that nodes don't change when you meve from one copy to another.
14:18 ShadowNinja    iisu: Also, the node ID field would take up more space since it has to represent every node from every mod that could ever possibly be added to the map.
14:19 ShadowNinja    iisu: As for the BLOB format, it's gzip'd.  See doc/world_format.txt for details.

14:29 iisu           If you add a new node you just add it to the array and new nodes will be identified by the new entry's index.
14:31 iisu           Supose the static array looks like this: { "default_air", "default_stone", "default_dirt" } Now each node of air is identified with a 0, as this is the first item in the array. Each stone is 1 and so on.
14:32 iisu           When you add, say, tree, you just add a new element to the array: { "default_air", "default_stone", "default_dirt", "default_tree" } Now each tree node is identified with the index of the new element which in this case is 3.
14:36 iisu           how do you make sure that every other copy of minetest agrees so that nodes don't change when you
14:36 iisu           eh, ctrl+v went wrong. I wanted to quote you.
14:38 ShadowNinja    iisu: I suppose that would work, but you now need to store and update that somwhere and you can never remove old entries since it would corrupt the map.  Without it you can't decode or save any blocks.  You'd have to make sure that you wrote it out redularly or the database could get corrupted.  The way it is now, if a block gets saved at all you know that its node list also got saved.  Also, right now you know there are a max of 4096 nodes
14:38 ShadowNinja    per block, but with that you wouldn't.  You'd have to use 16-bit or better ids in every block, although gzip might help make that somwhat reasonable.
14:38 iisu           Anyways, when you move to a different copy of minetest you can just pass your array so that the new copy would look up all the nodes in the old copy's array, compare the names with it's own settings and update the indexes in each node.
14:40 ShadowNinja    iisu: There are certainly improvements to be made though: https://github.com/minetest/minetest/issues/3946
14:40 iisu           A character is 8 bits and a string like "default_stone" is much more than just 2 chars.
14:42 ShadowNinja    Yes, but it's only stored once at the end of the block, not 4096 times.  And even if the blocks are a bit bigger, it may be wortth it.
14:45 iisu           "Only" once per block means "only" 4000^3 per map.
14:45 iisu           "s/3 /3 times "/
14:45 sfan5          the vast majority of blocks just have a single node: air
14:46 iisu           Anyways, I didn't come to suggest an improvement cause I'm a complete noob and I might be wrong. I just wanted to ask how you do it.
14:46 sfan5          you might also want to look at this script: https://gist.github.com/sfan5/52917a0e1338bcda2176edbc416dae60
14:53 ShadowNinja    iisu: Yes, but there's a tradeoff here.  You save space with node names, and lose it in node IDs.  A major disadvantage is that all of the blocks now depend on that one world -- which would make scripts that merge and split worlds much slower and much more complex. (I know that at least one person has made such scripts and used them on a number of worlds)
15:01 iisu           What does read_s() do?
15:03 sfan5          read bytes and interpret them according to the struct syntax (see https://docs.python.org/3/library/struct.html)
15:05 iisu           So the first byte of the BLOB is an unsigned char that states for a version of something, I assume of a map, yes?
15:06 sfan5          if you follow the code to see what it does with the version value you should be able to see what its for

16:02 iisu           Why I asked was because I had an idea for a mod but now I see it's not feasible. Also, it was a very lame idea.

20:02 Out`Of`Control Hi
20:02 bigfoot547     Hi
20:03 Out`Of`Control is it possible to add swim animation when its 2 or more nodes water
20:03 Out`Of`Control in depth
20:13 Sokomine       Out`Of`Control: guess it would be possible if someone creates a model that has such an animation
20:13 Sokomine       setting the animation at the right time might be more difficult
20:16 Out`Of`Control thanks
22:36 CalebDavis     ok i am trying to get the item name when an item is placed in a nodes inventory but idk how is there someone who does
22:42 calcul0n       CalebDavis, itemstack:get_name() ?
22:42 CalebDavis     ill try that
22:43 CalebDavis     it works thx calcul0n
23:11 red-001        wait so was the a legit k-line
23:12 red-001        or just a quite message joke
23:14 sfan5          quit messages look different
