I have a "TV channel" app running on a Raspberry Pi serving up local video content to a schedule I create. The Pi has a 5TB hard drive attached with perhaps 1000 videos or so. The app has a schedule and plays the videos according to the schedule. It starts up in the morning, plays tele-courses, moves on to old TV shows, an afternoon movie, after school shows begin around 3:00 PM, a comedy show around dinner time, an…

I just moved to the bay area. I made an app that scrapes all bay area events from meetup, eventbrite, and a couple of other sites- This way you end up with around 100 events a day, way too much to read through. So next I take each event, send it to chatgpt3.5 and ask it to rate this event on around 20 parameters. Next, I take the latitude/longitude of each event and measure driving distance from my house. Then I have…

I'd review the deck before the meetup, and then at the event, I'd not stress about names. I'd pretend to introduc…
