MySQL 8's SKIP LOCKED let them flip the model to one row per inventory unit instead of one row per item, and it held through Black Friday peaks of $5.1M in sales per minute.
Willison reads the published timeline and lands on a detail buried in the first bullet: the incident began during a training run, not an eval.

A Nature paper shows DeepMind's WeatherNext predicting cyclone tracks and intensity about a day earlier than existing models — its three-day forecast is as good as the old two-day one. Five days before landfall it gave Hurricane Melissa an 80% chance of hitting Jamaica as a Category 5, and forecasters used the lead time to warn earlier.
