    A good GraphQL server and client should be relatively straightforward to make in OCaml. Especially if you start from the premise that fragment spreads compose, rather than inherit.…

    Terminals are scary because it feels insurmountable. What are you supposed to do? If you just type “start python program” it gives you this absurd error that doesn’t make sense. Wh…

    It’s kind of the same argument as that for Node: having a singular language for everything you do lets you have “thick” tightly coupled packages that do everything, which you can c…

    This was kind of true for Spain: they imported so much silver that they had inflation causing massive economic destabilization.

    In your mind is 700 files a lot or a little? It feels very small to me, and Xcode really ought to be able to handle that tiny scale on modern machines with ease. I struggle to imag…

    It’s probably the lawns and yards, primarily. Including things like pools: in Arizona there’s about one pool for every 13 people. The US averages much larger lot sizes, and those y…

    Most code I’ve seen is written in an environment where people can’t afford to “intuit”: thinking through the repercussions of specific language or algorithm choices comes second to…

    It’s reasonable for people to take either approach: are microplastics more like asbestos or are they more like cellulose in terms of harm? The answer being unclear means it makes s…

    Couldn’t the school just build taller too?

    No. In most American suburbs you can get more density by taking 2 single family homes and replacing them with one 6-plex. You’ll also have more open space, because a 6-plex takes u…

    “Half one” is archaic English, and common German, for 12:30. Similarly “my 27th year” just sounds archaic to me: I wonder if you went through a bunch of 19th century writing if you…

    So long as only 10% or less of your incremental successes are mirages, and so long as the downside of shipping a mirage is only a small incremental harm, then shipping 9 success an…

    In your scheme, how do I transfer money from my bank after my phone is stolen and I need to get a new phone without access to the original sim? Or access my email? If that’s just i…

    On the parks/“natural land”: would you rather land exist as an empty razed dirt field for speculators to wait to sell, or given back to the city? Taxing the land value means there’…

    There is absolutely not an oversupply of apartments in my city, nor in Seattle proper. it should be non-controversial to let the market supply as many apartments in the locations p…

    More accessible. People with walkers can access the apartment, as can people in smaller wheelchairs, if there is a small elevator. In NYC plenty of older people live in pre-war bui…

    Which ties into a second problem: the US especially requires elevators to be too large, which limits how many are built because they take up so much square footage, which drives up…

    Double loaded corridors fundamentally change the composition of buildings. If you look at example floorplans, single staircase buildings typically feature 2-3 bedroom apartments, b…

    A key advantage of trains is they can be fully electric and don’t need to carry their entire fuel load on board. An electrified train running on nuclear or wind supplied power basi…

    Right, we have 50+ years where motor vehicle involved deaths are like 15-20% of all deaths for people under 50, not to mention how many more people are permanently injured due to m…

    Allowing infill development of existing parking lots to create mixed use neighborhoods is in reality very cheap for cities to do. All it costs is rezoning: if they then increase ta…

    The subway doesn’t keep to a strict schedule (it has one in theory but no one would depend on it), and has anywhere between 3 and 20 minute headways (time between trains). You can …
