"i realize from coming here over the last year -- parts of my brain have atrophied" "I never studies CS, but find myself writing software." Go to supermarkets to buy food. Weekly sheets, similar to Safeway's weekly

Someone at safeway, responsible for buying ... $12bn of food per year. Chief merchant. Lots of fiefdoms. No one coordinating. All the associated products. PUtting all the independent little bits, on sale. You have space to put 500 familes of items. And then you figure out which items you need , to

Have to score promotions. And have to put them on a page.

Restuarant. Everyone things of the core items, big ticket. Really, restaurants make money on the side items, sodas.

Personalizing. By time.

Adoption. Of TV. 1950 - 1980. Of

Paper has some magic. Sending flyer or not, is clear.

Mass personalization. Vs individual.

Apache Iceberg data format. Like Parquet
