I've been screwing around with evals - here is my first one!
I know many of you are AI haters but its here and its real.
For this case I've looking at speed, accuracy and cost for solving hard NYT connections.

One of the notions we think about quite a bit at @motherduck.com is "handling data before it becomes big" and I think this example from @tigrisdata.com really nails it. The trick here is parsing the JSON on insert so its really quick to query it.
AI scrapers can overload your app before you even see them coming.

vibe coded my way through adding tiebreaker logic to mdsinabox.com/nba today, and of course discovered there is some ambiguity in the tiebreaker rules as described on nba dot com. it is also potentially non-deterministic if there is a tie for the 6/8/10 seed
