Saturday/ the heat is on

We got to 101 °F (38°C) here in the city today, and it will be even hotter tomorrow and Monday.
Four of us played tennis in the morning until noon or so, by which time it was  already 90 °F (32°C). A good time to call it quits.

Here’s the new blue car getting its first wash at Uncle Ike’s Carwash. It was really a quick rinse only, with the water sprayer. (Driving in the dusty parking lot by the upper tennis courts at Amy Yee Tennis Center had coated it with fine dust). As soon as I started to drive away, the automatic windshield wipers sprung into action, wiping away the water beads. Rain-sensing wipers typically use a sensor mounted behind the windshield. It sends out a beam of infrared light that, with water droplets on the windshield, is reflected back at different angles. Tesla cars use its autopilot cameras to feed its computer vision neural network to determine the need, and the speed for the wipers.
