  • Referring to Carney’s visit, the Chinese envoy emphasized that “Canada reaffirmed its long-standing commitment to the one-China policy,” and to “respect each other’s sovereignty and territorial integrity.”

    He did not mention Taiwan explicitly, but it seems the first faint sparks of coercion are already here.

    lol. Assertion of sovereignty always requires force. To label the force necessary for the assertion of sovereignty as coercive or not is a political choice. Just ask the Confederate States of America.





  • Thank you for the take. I saw the bologna slice sandwitches in a YouTube video before but didn’t know what to make of them because I never went.

    Don’t know too much of the riots except they happened and that there are pro and anti government sides.

    How does the food situation compare to other islands?

    Do other islands import food? Did you get why Cuba doesn’t have a variety of food? No imports or can’t grow in Cuba?

    Would like to know why the food situation is like that. They have a large island so don’t know why it’s like that.









  • Two (related) questions + one other question

    I know this is a long way off, but, what do you think will happen to people in your position when autonomous cars become actually real? (Do you have a back up plan)?

    Related to above, do wealthy people care about their staff (chauffeur, chef, concierge, gardener, etc) in a human way? I’d imagine if not, they would replace their staff with automated equivalents when they’d feel they’re both equivalent.

    How do sick days and holidays work?


  • Your example is incorrect.

    • All cats are peanut butter (c is a subset of p)
    • some peanut butter are dogs (p intersects d, or, d is a subset of p)
    • some cats are dogs (c and d intersect, or, d is a subset of c)

    The first two do not make the third.

    You can have:

    • c is a subset of p,
    • d and p intersect,
    • The section of p that intersects with d does not contain any c

    To fix this, reverse the first statement.

    • All peanut butter are cats (p is a subset of c)
    • some peanut butter are dogs (p intersects d, or, d is a subset of p)
    • some cats are dogs (c and d intersect, or, d is a subset of c)

    Any portion of d that intersects with p (some p is d) must also be c (since all p is in c). Hence some c, but not all c, is in the portion of p that intersects with d (some c is d).



  • I think you’re missing the general point.

    In the cases you’ve described, having automated semis would not be feasible. Automated cars already have a hard time in San Fran and AZ cities with smooth asphalt as it is.

    The places where automated semis make the most sense, i.e. large, well maintained highways connecting large urban centres, can be better served with automated railways.

    The engineering is much simpler, fewer degrees of freedom and a much more constrained problem space (and hence constrained solution space), for automated railways than highways. Creating a safer environment for all. Also not having to deal with semis as an individual driver.

    Railways (funded through private investment): https://www.aar.org/wp-content/uploads/2025/01/AAR-Rail-Network-Map-2025-1.jpg.webp

    Highways (publicly owned, operated, maintained): https://www.fhwa.dot.gov/planning/images/nhs.pdf

    There is some good coverage with railroads, but as you said not nearly extensive as the public road network. But I bet you the vast majority (above 60%) are along corridors with railways. However two big hurdles need to be overcome, greater investment in throughput capacity and the fact that trucks can go from ware house to ware house.

    However both issues can be solved.
