    Rethinking open source in the context of the coronavirus pandemic

    I think you'll get some good feedback from this sensible presentation. I have some minor points.

    Re: "it might be more pragmatic to officially open up the designs than to fight the copies." -- Wouldn't dealing with
    support requests for counterfeits still take up staff time?

    Re: "The pandemic has increased awareness about potential benefits of manufacturing locally" -- I'm not sure this is true. It might show the opposite, that global trade is so important, especially during a pandemic, that government should be prevented from interfering in it, via tariffs, for example. At least, I hope so.

    Re: "we could open up some existing products after exceeding some donation threshold" -- it might be more sensible to solicit donations after a particular product is opened up.

    And finally, you didn't mention it, but your various bits of firmware could be made into free software.

    If you're willing to have the robot run the course from memory, it could steer wider on the curves and cut the corners to achieve a faster time. What do the rules say about how close to the course the robot has to be?

    On losing my baby

    Candice and Jan,

    Our condolences to you and your family for your loss. Thanks for sharing the story.

    I would have had a brother 17 months older than I if he hadn't been stillborn, with
    hydrocephaly; they were worried about me when I was born because I had a big
    head, and because I didn't start talking until age 3. We recently found what we
    think is the location of his grave in Lubbock, Texas, and my sister Kris visited it.
    Perhaps we'll add a marker.

    I've downloaded the Liszt piece and will attempt it. I have a good piano teacher now,
    so it might eventually be possible.
