Cookies and Watermelon

Laura made some oatmeal chocolate chip cookies today:

After 11 months, she's finally got the very finicky oven figured out.

We also splurged and bought a whole watermelon at the grocery store. Pretty good:


We bought and shipped some souvenirs home. The shipping was more than the cost of the items, but worth it to us.


I started reading The Calculating Stars by Mary Robinette Kowal. It's this year's Nebula Award winner, so I thought I'd give it a whirl. Very good so far.


I read a lot about non-negative matrix factorization. I'm still trying to figure out how to assess said factorizations and to figure out how to use them for dimension reduction.
