  • As already mentioned, the blue book by Evic Evans is a good reference, but it’s a ittle dry. Vaughn Vernon has a book, “Implementing Domain-Driven Design” that is a little easier to get into.

    Personally, I found that I only really grokked it when I worked on a project that used event-sourcing a few years back. When you don’t have the crutch of just doing CRUD with a relational database, you’re forced to think about business workflows - and that’s really the key to properly understanding Domain-Driven Design.


  • I’ve always understood DRY to be about not duplicating concepts rather than not duplicating code.

    In the example here, you have separate concepts that happen to use very similar code right now. It’s not repeating yourself as the concepts are not the same. The real key is understanding that, which to be fair, is mentioned in the article.

    IMO, this is where techniques like Domain-Driven Design really shine as they put the business concepts at the forefront of things.






  • And at this point, the extended crew of the Discovery was thoroughly sidelined: Burnham’s personal relationships took priority over everything else.

    This is the part that I’ve never got on well with in Discovery.

    In TNG, it’s not a show about Picard, or Riker, or any of the other individuals. It’s a show about the crew. I’ve even seen it said that the actual star of the show is the ship.

    Whereas, with Disco, it’s a show about Michael Burnham and everyone else has a bit part. That always felt weird for a Star Trek show. I want to see how the crew works together to solve problems and overcome things with everyone on an equal footing regardless of their rank in the show.

    And I think that’s why there was such a warm reception to season 3 of Picard. It brought the crew back together. Picard alone isn’t satisfying enough. What we wanted was him as part of the crew.


  • Same, using Chat GPT 4. It explained the steps without prompting, which is different from the single line answer shown in the post too. I got this…

    Let’s break this down step by step:

    1. Sally has 3 brothers.
    2. Each of those brothers has 2 sisters.

    Sally is one of those sisters for each of her 3 brothers. Therefore, the second sister that each brother has would be the same other sister.

    This means that Sally has only 1 other sister, making a total of 2 sisters in the family (including Sally herself).

    So, Sally has 1 sister.
