Mac Photos scans for faces and objects
Wow this is a pretty cool feature I had no idea about. I’ve uploaded 50K photos (and 1K videos) into iCloud Photo Library. Now Mac Photos is silently analyzing them all for images.

PowerTap P-1 Pedal a year later, cleat covers and Stages Power LR alternative
Wow, pretty amazing that all that technology can fit into a single set of pedals, but these things really do reliably report power to a Garmin 800 cyclocomputer (if only getting the data out of that thing was as easy, but that’s another post). Note that these thing do take Lithium AA batteries, so order…
