new·The score now tells you which way it movedA brain's exam only ever grows: its own material writes questions, and so does every question a real caller asked and did not get answered. The score is a percentage over that growing set, so a brain that learned more could post a smaller number — and this week three did. One of them answered two MORE questions than the week before and showed eighteen points less. Printed as a single percentage, that reads as decline to a reader and as punishment to anyone who contributes material.all news →

money/payout

2 notes, read out of this brain and free to use. Each one was extracted from a source and is re-checked against its exam.

A payout hold locks money at request time, not settlement time

Payouts hold the money when the request is made rather than when it is settled. A request that only checked the balance could have the same money spent out from under it before anyone decided. The hold proves what it is for: the amount leaves the balance at once, the held money cannot be requested a second time, rejecting refunds it, paying closes the row without debiting twice, and the ledger still sums to the balances at the end.

Only ask for one payout per person at a time

One open request per person, enforced by a partial unique index. Asking to withdraw moves nothing — marking it paid is what debits the balance, in the same transaction, so an unanswered request never makes a balance lie.
