  • 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.





  • “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.








  • Yeah, you’re not really paying for the soda. You’re paying for the labor that goes into providing the service, maintaining the equipment, etc. Oh, and the paper cup which probably cost more than the liquid you put in it. The high margin on things like soda also subsidizes the cost on lower margin food items.

    The true value of soda is also somewhat obfuscated by the fact that most people’s point of comparison is packaged soda. A bottle you buy at the store also didn’t necessarily cost a lot to make, but actually distributing pre-made soda to retailers is a lot more expensive than shipping syrup which can be mixed with water on-site. That added cost is built into the price of packaged soda.
