  • You point out the key weakness to the whole approach (dependency on a single third party). Though I suspect that the content in question is also hosted by NaviLens, so the codes would still stop working if they ever shut down.

    Just taking a look at their website, it seems to me that NaviLens’ value proposition isn’t just “codes that download a document”, but an entire framework for building and presenting essential documentation in a way that is accessible to people with vision impairments. I can see why it would be cheaper and more effective for a city to buy a service like this than to hire their own software developers and accessibility experts to build out their own bespoke system.








  • Food, especially fresh food, used to be a lot more expensive when adjusting for inflation. A canned chicken like this doesn’t look super appetizing right out of the can, but it probably tasted OK after you shredded it and put it in a casserole. And it was significantly cheaper than buying a fresh whole roasted chicken, assuming you lived somewhere that fresh whole roasted chickens were even readily available. Food like this became particularly popular during the great depression, and stuck around for decades afterwards.

    Nowadays, between industrialized farming, highly optimized supply chains, and a buttload of government subsidy, fresh food is comparatively cheap. You can get a whole roasted chicken right off the spit for $5-10 at just about any grocery store. So for most people the value proposition of a $3 canned chicken isn’t really there anymore, especially if you don’t have an enormous baby-boom-era sized family to feed.


  • “Arithmancy” is their name for math classes and is mentioned several times throughout the books. It is one of Hermione’s favorite subjects.

    At one point, the real world evil witch that is JK Rowling suggested that Arithmancy is like dviniation, but with math, saying they use numbers to predict the future. I take this to mean that the wizarding community discovered calculus independently from the rest of the world and mistook it for a new form of magic.
