  • Please don’t lump trademarks with the rest. Makers have stamped their goods with their mark since ancient times, both as advertising and to signify quality products (and not knockoffs). Swords were especially commonly marked with the smith’s trademark.

    It was illegal to sell bread in ancient Rome without a trademark, for example. The punishments for doing so were harsh, as they wanted to be able to track down the baker if someone sold tainted bread.

    In modern days, they’re useful for customers to know what company they’re buying from.




  • It’s necessary to split it out into different tables if you have a one-to-many relationship. Let’s say you have a list of driver licenses the person has had over the years, for example. Then you’d need the second table. So something like this:

    SSN_Table

    ID | SSN | Other info

    Driver_License_Table

    ID | SSN_ID | Issue_Date | Expiry_Date | Other_Info

    Then you could do something like pull up a person’s latest driver’s license, or list all the ones they had, or pull up the SSN associated with that license.


  • Theoretically, yeah, that’s one solution. The more reasonable thing to do would be to use the foreign key though. So, for example:

    SSN_Table

    ID | SSN | Other info

    Other_Table

    ID | SSN_ID | Other info

    When you want to connect them to have both sets of info, it’d be the following:

    SELECT * FROM SSN_Table JOIN Other_Table ON SSN_Table.ID = Other_Table.SSN_ID

    EDIT: Oh, just to clear up any confusion, the SSN_ID in this simple example is not the SSN itself. To access that in this example query, it’d by SSN_Table.SSN










  • When I’m driving, it’s actually unsafe for my car to be operated in that way

    being able to consistently and reliably operate the thing without taking your eyes off the road

    Considering they’d just spent the previous few questions discussing the visual-first aspect of touchscreens and accessibility issues for the visually impaired, I think that’s exactly what they were talking about.

    The generalizations are about completely different devices. They talk about CT machines & automatic defibrillators later.

    An advantage of funding things via a collective like Nebula as opposed to each individual creator managing their own patrons is that new creators can start making bigger, more expensive projects quicker. Even established creators have this advantage, they can take bigger risks on bigger projects with the safety net of a share of the nebula pie.

    I don’t think a project like The Prince would exist without Nebula, for example.
