8 versions of UUID and when to use them
  • You don't quite understand. One of the major drawbacks of UUIDs over monotonically increasing id's is the lack of ability to sort them. Not just for manual querying, but for index operations, caching, data locality etc.

    It's very handy and is a big part of the reason why Twitter developed Snowflake IDs, which are basically like UUIDs v6 and v7.

    The UUIDs specs are quite easy to understand and definitely not "enterprisey".

    They chose "version" because they are just that, versions. Improvements over the original design that benefit from new insights and technological improvements. We're lucky they had the foresight to include a version number in the spec.

  • robots.txt is a suggestion
  • No it's not, what a weird take. If I publish my art online for enthusiasts to see it's not automatically licensed to everyone to distribute. If I specifically want to forbid entities I have huge ethical issues with (such as Google, OpenAI et. al.) from scraping and transforming my work, I should be able to.
