You’ve probably got a smartphone. Does it ever confuse you, or do anything you don't expect? When you have a question, where do you get answers? From friends? YouTube videos? Many of us just click different things and hope for the best.

Smartphones do wonderful things, but they’re also tricky, sometimes inscrutable, change frequently, and are almost essential in the modern economy. Today’s guest on Davisville, Louie Toro, is teaching classes this winter and spring at Davis Adult and Community Education for people who want their smartphones to be less of a black box. We talk about common questions (“a big one is almost always downloading files”), how he teaches, and how to live more of your life outside your phone. The phone is “just a tool,” he says. “You should be the one who chooses how to use that tool.”

Today's subjects: January garden calendar, more on evergreen shrubs for screening, mandarin varieties for a long season of harvest, pruning peach and nectarine trees, and more.

It all started with one song, "What Was I Made For?" by Billie Eilish. I answered that question in just a few songs. Today you can hear 30 minutes of great tunes explaining her question.
