  • Smart washing machine: ours is in the basement and my wife and I used to regularly forget we had laundry in it. I now have Home Assistant text us when a load is complete. But it only texts us if we are home and can do something about it. If nobody is home it waits until one of us gets home to text us.

    BUT: The washer and dryer are still dumb, pre-IoT generation. I built light sensors that are taped to the displays, and Home Assistant relies on those to determine if the appliances are on or off. No need for cloud-based monitoring, etc. A little creativity like that can work just as well or better than a convenient cloud-based solution.




  • I grew up boating up and down the New England coast. As long as there are big boats in the water there will be a need for good mechanics, and plenty of boat owners willing to throw money at you.

    I remember stopping at a marina for fuel once and we saw a mechanic replacing an outboard engine on one of those big “cigarette” boats that often have 3 or 4 engines on them. We struck up a conversation and learned that the boat owner was a rich idiot who didn’t know how to operate the boat properly and would blow an engine almost every time he took the boat out. It happened so often that the mechanic had started keeping a spare $20,000 engine in stock just for this boat. He was more than happy to take money from the idiot boat owner to keep the guy happy.



  • I’ve been driving for a few decades now and I’ve seen plenty of edge cases during that time where driverless cars likely wouldn’t do very well. A few recent examples:

    • A car on fire in the middle of an intersection. Cars drove around it on the red light to make way for approaching fire trucks.
    • I stopped at a red light at a construction zone and was watching for the light to turn green, and didn’t see a police officer standing next to the construction crew trying to wave me through. I finally noticed him when he yelled at me.
    • There’s a traffic light near me where two roads intersect at about a 30 degree angle. You regularly see both the red & green signals for both roads when stopped. I’ve seen Teslas that misread red signals as green be cause of this.
