    Where does it say that I lived in the US my whole life? You're getting ahead of yourself. From another blog post: > I grew up in Europe (mostly Germany, Denmark, Switzerland). I ha…

    I'm amazed that this is still an ongoing discussion. All of these "studies" have been distracting with muddied data from a very simple, unambiguous scientific fact: alcohol is a po…

    I've had the same thought for a long time. I think this is spot-on. Ballmer is underrated in that he put Microsoft into a profoundly well-resourced position that a better product l…

    I've been very happy with Dynadot. I don't like that domain hosting is just one of many products for Cloudflare and others (as we've seen come up for Google!) and have had bad expe…

    Any idea how it was quoted without being published?

    The natural monopoly emerges from the economy of scale: eventually you are offering a product at a price that nobody else can profitably undercut, because they do not have the same…

    Hi, author here. This is a good point that's worth addressing. Technology is not the reason it's a winner-take-most market. It's helpful, but in the long term, many players will ha…

    Author here - not an ad, I don't even know anyone at Waymo and don't hold any associated financial incentives.

    "In places with working public transit" is a huge caveat here. The vast majority of the US does not have what I would consider "working public transit". And those places aren't goi…

    Hello! Author here. Quick responses: 1) With superior scale, the utilization of each Waymo approaches 100%. "Empty rides" going to a new pickup spot become more and more rare becau…

    Create one DB for the whole test suite, and then re-instantiate tables/schemas on every unit test.

    Worrying about the environmental impact of books is misguided. You use far more paper products in the course of your everyday life: paper bags, cardboard packaging, paper towels, e…

    Not to distract from your point, but you mean topography, not topology.

    You really expect to open a bank account anywhere in 2024 without KYC?

    Not anymore. Online banks like Mercury will do it entirely remotely without any residency requirements, IIRC.

    I don't think there's anything wrong in making a traditional label that conforms to all other labels (i.e. looks aged). That's a design choice, and design choices that appeal to tr…

    This is a severely regressive policy, and -- by the way -- already the case. The vast majority of per-student resources are spent on the bottom 20% by performance.

    How many messages are you expecting to send? 300 - 500 USD/mo suggests hundreds of thousands of messages. Are you expecting thousands of users? If so, any chance that some of your …

    Yep! The only thing that remains is to focus on that code being properly functional; i.e. avoiding side-effects. Side-effects and parallelism don't mix well. Wonder if this will gi…
