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 →

Creating time-series queries with SQL macros

To create a time-series query using macros, select a macro like $__timeGroup or $__timeGroupAlias from the Data operations drop-down, select a time column from the Column drop-down, and select a time interval from the Interval drop-down.
