John@0 1 -- lists consist of three things
John@0 2 -- 1) a base state - agreed on by one or more list holders
John@0 3 -- 2) change sets - incremental list changes (can be rolled forwards or
John@0 4 -- backwards)
John@0 5 -- 3) working state - not saved because it can be so easily calculated

John@4 15 -- notes on list storage:
John@7 16 -- Using names as keys as I do now is atrocious.
John@4 17 -- It prevents insertions (twss) to the middle of the list because then it acts
John@4 18 -- as a side effect onto all the others. ie ABCD -> AXBCD would be phrased as
John@4 19 -- "insert X and shift down B,C,D" which sucks. BCD haven't really been affected
John@4 20 -- (yet) because their relative positions to the others are still intact - ie
John@4 21 -- they are still below A right where they belong. But really X hasn't done
John@4 22 -- anything to affect their relative standing.
John@4 23 --
John@4 24 -- Ok so we can't use names.
John@4 25 --
John@4 26 -- We can't use monotonic integers either because it suffers the same problem.
John@4 27 -- Also consider, randoming in someone to a list of ABCD. Say they roll spot 2.
John@4 28 -- What if someone else runs a separate raid and also randoms someone into slot
John@4 29 -- 2? How do you handle that conflict? Difficult. Also, consider this:
John@4 30 -- List of ABCD on night 1.
John@4 31 -- Admin 1 on night 2 rolls in 30 new people. ABCD's indexes are shuffled to be
John@4 32 -- between 1-35.
John@4 33 -- Admin 2 on night 3 rolls in 5 new ones and people ABCD and PQRST now all have
John@4 34 -- indexes between 1-9.
John@4 35 -- When these two are resolved against one another, do the 1-9 peopole end up on
John@4 36 -- top of the list compared to those other 30?
John@4 37 --
John@4 38 -- Solution:
John@4 39 -- Need a huge random space with purposely left gaps to leave plenty of room for
John@4 40 -- conflicts.
John@4 41 -- So if ABCD had randomed on a space of say, 10,000 and then were sorted into
John@4 42 -- order, then the next 30 could roll into that same space and have a proper
John@4 43 -- ordering. Then the next 5, etc.
John@4 44 --
John@4 45 -- Handling conflicts:
John@4 46 --
John@9 47 -- Executive decision: random on a range of [0,1], ie math.random
John@9 48 -- then on an add-to-end event just do last + .1
John@9 49 -- disallow random after any add-to-end event occurs
John@9 50 -- because the list either elongates beyond 1 OR becomes
John@9 51 -- ridiculously bottom heavy, thus meaning that randoms
John@9 52 -- don't get an even distibution from then on (in fact
John@9 53 -- they'll end up getting top favor)
John@9 54 -- * if a stream contains a random-add after an add-to-end
John@9 55 -- it is declared invalid. tough tits. it's just not a fair
John@9 56 -- distribution at that point.
John@10 57 -- * actually, fuck it. I'll give them an unlock command and
John@10 58 -- let them screw over their lists :)
