  • A file is an arbitrary string of bytes. Removing the ability for the user to handle them like this is so obtuse.

    Per the article:

    According to the BTRON3 specification, the first two halfwords of an application ID are the data type it applies to, and only the third distinguishes rival handlers for the same type. When a document contained writing, a table, and a figure, opening those parts made the system launch each one’s registered handler to draw its own content inside the parent document’s window. If no handler exists, or the handler fails to draw, the system strikes a diagonal line through the region where the content should have been.

    That’s a window manager with application/file associations, with the ‘window’ that the application draws to being embedded within a hypertext document. So, you’d be able to attach arbitrary hypertext to a file and when you open it the window manager presents that information along with the application window. That’s not any less flexible or more limited than any other desktop OS.

    IMO you’re much too charitable. I think these are the reasons (at least for American conservatives), roughly in order of what I consider to be the most to least sympathetic:

    • A fondness and nostalgia for fossil power. To be clear I think if this is the reason you’re supporting fossil fuel use when lives are on the line you’re crazy, especially when museums and motorsport categories for older engine technologies can (and already do) exist, but I can at least understand it.
    • Anxiety about change. While there are lots of reasons to think that renewables will put us in a better position than fossil fuels (they’re cheaper, can be less centralized, and better insulated against geopolitical instability) a lot of people are very anxious about things like EV range and grid instability. If they’re a “low information voter” or have been fed a steady diet of oil industry propaganda then they probably have a very exaggerated view of these issues and a very poor understanding of how the world works.
    • The entire idea of anthropogenic climate change and things like a circular economy directly contradicts the Christian worldview they’re operating under. For one they don’t believe in climate change for the same reason they don’t believe in herd immunity from vaccines or systemic racism. Cumulative effects, dynamic systems, and tipping points aren’t part of how they think the world works. Secondly, they view the world as something their god gave to humanity to conquer, dominate, and exploit. Telling them that they can’t suck the world dry and throw away the husk come judgment day is tantamount to telling them their religion is fake.
    • For a portion of the population the above three attitudes have metastasized into conspiracy theories and fascist ideologies. Things like a belief that “15 minute cities” means they will be put into open air prisons, or that wanting to reduce resource consumption means that they will be subjected to population control so that black people can replace white people. I don’t feel like writing a giant comment examining the core of the reactionary mind, but suffice it to say that things like language and truth are very fluid for them. If something makes them feel bad then it must be bad, literally and physically. The conspiracy theories are created to justify the feelings.
    • In addition to the above plenty of people want to hurt others. The fact that large powerful vehicles kill people, the fact that they’re loud, inconvenient for others, and spew black smoke, makes them more appealing. The fact that oil use creates wars that kill children is a bonus. All of this is tough and manly. It makes them feel good.


  • Maybe they could be synced using RF over fiber. This has been proposed as candidate technology for 6g wireless networks, to enable cell free massive MIMO.

    That would mean that you would need to run optical fiber to each of them, though we’ve already seen fiber drones spool out kilometers of the stuff as they fly.

    EDIT: I just remembered this interesting article about doing radio interferometry over a fiber network using cheap quartz oscillators instead of atomic clocks. My (layman’s) understanding is that the quartz oscillators are good enough over a few milliseconds, but will fall out of sync with each other over longer time spans. Meanwhile the fiber optic reference signal (distributed from a central atomic clock) can be kept correct on average by reflecting the reference back down the fiber and doing active correction of the changing path length (caused by thermal fluctuations and vibrations along the fiber) but will be incorrect on a millisecond-to-miliscond basis because of light speed lag and the path length being a moving target. So they use the quartz oscillators over small time scales and use the fiber reference signal to keep them synced over long time scales. Surprisingly the article says they actually get a better sync this way than with using multiple atomic clocks.

    So perhaps something like that is possible.




  • The usage rates in Japanese cities are among the highest in the world, as are the punctuality and reliability of the intercity trains.

    Could the system be less convoluted? Absolutely. But IMO most European countries aren’t in much of a position to criticize given that they aren’t even willing to step up to the plate to anywhere near the same degree, to say nothing of North America.

    Now, one might argue that this has more to do with city form than it does with the quality of the PT infrastructure, but that is infrastructure too, and those two types of infra are two sides of the same coin. And yeah, the city form isn’t completely perfect either, but when it comes to moving a greater proportion of people in the safest and most energy and space efficient way, the numbers are just higher than most other places.
