    In theory you can do filesystem-copy-speed population of large seed data using InnoDB's transportable tablespaces feature. For the test db use-case specifically though, unfortunate…

    Case sensitivity/insensitivity is a property of the collation, which is configurable on a per-column basis. In Postgres the default collation is case-sensitive, and in MySQL the de…

    The articles I read yesterday indicated that it would be quite difficult to determine country of origin in many cases, due to complete lack of official identity documentation. The …

    Pardon my skepticism, but cursory web searching and LLM prompting is giving me responses like "a significant portion of the European Roma population faces high rates of statelessne…

    Which is where, exactly, for the people in question? i.e. what is the legal home country for most Roma in Denmark? Given folks like DHH have such strong opinions about this, I woul…

    I meant in the sense that Roma are an ethnicity lacking their own sovereign state, "stateless" as in https://en.wikipedia.org/wiki/Stateless_nation

    If some individuals are committing crimes, why isn't the normal criminal justice system the answer, instead of deportation? And deport them to where exactly, and on what justificat…

    > the PostgreSQL MVCC approach is well worth never seeing ORA-01555 like error message. But that's a false comparison; it's not a binary decision. As InnoDB demonstrates, you can t…

    If you steal an unpopular product from a store, the damage is also only to "potential profits", so how does that differ? It's entirely possible no one would have purchased the prod…

    My point is that the number will entirely vary for each user, depending on how many poor DB-related infra decisions they've made. Some users may save 99%, others may save almost no…

    I don't see how that would be a realistic risk? Any MariaDB user (including Lobste.rs) could request the source, and per the GPL it must be supplied, so this isn't an effective str…
