John@17 19 -- holy crap long notes {{{
John@4 20 -- notes on list storage:
John@7 21 -- Using names as keys as I do now is atrocious.
John@4 22 -- It prevents insertions (twss) to the middle of the list because then it acts
John@4 23 -- as a side effect onto all the others. ie ABCD -> AXBCD would be phrased as
John@4 24 -- "insert X and shift down B,C,D" which sucks. BCD haven't really been affected
John@4 25 -- (yet) because their relative positions to the others are still intact - ie
John@4 26 -- they are still below A right where they belong. But really X hasn't done
John@4 27 -- anything to affect their relative standing.
John@4 28 --
John@4 29 -- Ok so we can't use names.
John@4 30 --
John@4 31 -- We can't use monotonic integers either because it suffers the same problem.
John@4 32 -- Also consider, randoming in someone to a list of ABCD. Say they roll spot 2.
John@4 33 -- What if someone else runs a separate raid and also randoms someone into slot
John@4 34 -- 2? How do you handle that conflict? Difficult. Also, consider this:
John@4 35 -- List of ABCD on night 1.
John@4 36 -- Admin 1 on night 2 rolls in 30 new people. ABCD's indexes are shuffled to be
John@4 37 -- between 1-35.
John@4 38 -- Admin 2 on night 3 rolls in 5 new ones and people ABCD and PQRST now all have
John@4 39 -- indexes between 1-9.
John@4 40 -- When these two are resolved against one another, do the 1-9 peopole end up on
John@4 41 -- top of the list compared to those other 30?
John@4 42 --
John@4 43 -- Solution:
John@4 44 -- Need a huge random space with purposely left gaps to leave plenty of room for
John@4 45 -- conflicts.
John@4 46 -- So if ABCD had randomed on a space of say, 10,000 and then were sorted into
John@4 47 -- order, then the next 30 could roll into that same space and have a proper
John@4 48 -- ordering. Then the next 5, etc.
John@4 49 --
John@4 50 -- Handling conflicts:
John@4 51 --
John@9 52 -- Executive decision: random on a range of [0,1], ie math.random
John@9 53 -- then on an add-to-end event just do last + .1
John@9 54 -- disallow random after any add-to-end event occurs
John@9 55 -- because the list either elongates beyond 1 OR becomes
John@9 56 -- ridiculously bottom heavy, thus meaning that randoms
John@9 57 -- don't get an even distibution from then on (in fact
John@9 58 -- they'll end up getting top favor)
John@9 59 -- * if a stream contains a random-add after an add-to-end
John@9 60 -- it is declared invalid. tough tits. it's just not a fair
John@9 61 -- distribution at that point.
John@10 62 -- * actually, fuck it. I'll give them an unlock command and
John@10 63 -- let them screw over their lists :)
