00:30 Zughy[m]  hurray, back again to 100 PRs
02:36 proller   Zughy[m], just reopen https://github.com/minetest/minetest/pull/12142 to be 101s
10:58 MTDiscord <paradust> Why is blockdata serialized as three separate arrays (array of all param0, followed  by param1, followed by param2) instead of just copied node by node?
10:59 MTDiscord <paradust> oh probably a compression thing? nevermind
11:06 MTDiscord <luatic> Also useful on the Lua side of things (VoxelManip): Having three large arrays has much less overhead than having one large array where every entry is a table of 3 values.
11:08 celeron55 also generally one is interested in a single param across multiple neighboring nodes, so you want to store them in separate arrays as a cpu cache optimization
12:38 MTDiscord <paradust> but their in-memory representation is a single array, it appears

14:05 sfan5     it is indeed
14:05 sfan5     but for serialization it'll be to optimize the compress yeah
