00:17 muurkha   erle: the PDP-11 did it by making a copy of the whole process's memory space, either in RAM or, if necessary, on the swap disk
00:17 muurkha   Unix on the PDP-7 only had the latter option
00:19 muurkha   but on a paged machine like the 386 you could do it by just changing the parent's mappings to be copy-on-write, if you simultaneously reserve enough pages to handle those copies should they in fact be needed
00:19 muurkha   in the swapfile, potentially, rather than in RAM
00:20 muurkha   you can unreserve them on execve() or _exit()
16:11 json      Hello all!
16:11 json      good by all!
16:11 srifqi    hello
16:11 json      no
16:13 json      srifqi just so you know, I'm not participating in minetest, but I'm following the development closely
16:15 srifqi    it's also fine. hope you find it nice here
16:15 json      thank you!
16:18 json      hello!
16:22 json      It's a pity that there are no posts on the official blog for these months.
16:23 MTDiscord <greenxenith> Ah damn, I was supposed to work on the draft last week. Things got busy though
16:23 MTDiscord <greenxenith> I'll write that up tomorrow
16:27 erle      yes i did submit stuff
18:02 MTDiscord <mistere_123> > getting busy Understandable
19:41 erle      if i want a variable spacing in a for loop in lua, how to achieve?
19:41 MTDiscord <luatic> variable spacing?
19:43 erle      luatic so i have this https://git.minetest.land/erlehmann/tga_encoder/src/commit/4d57ba62bf4e499ecadfbd50916e16484a26f86d/donut.lua
19:43 erle      luatic set theta-spacing to 0.01 and the point cloud appears solid
19:43 erle      set phi-spacing to 0.2 and the donut is made out of rings
19:44 erle      now what if i want a thing where the spacing is variable when going around the center of revolution of the torus
19:44 erle      or when going around the cross-sectional circle of the torus
19:44 erle      how to do
19:44 MTDiscord <luatic> you want to change the loop step while looping?
19:44 erle      yes
19:44 erle      so i can have donut which is solid at one end and not at other
19:45 erle      i mean it only appears solid obviously
19:45 erle      it is still a point cloud
19:45 MTDiscord <luatic> i suppose you'll be best of with a while loop + a local variable then
19:45 MTDiscord <luatic> best off*
19:45 erle      everything in games is smokes and mirrors (except smoke, which is particle systems … and mirrors, which is another camera)
19:46 erle      i must confess i made reflections in a level once by flipping it upside down and having transparent texture hehe
