  • Another commentor pointed out a legitimate use case, but it’s not even worth thinking about that much. De-duplocated is usually a word you use in data science to talk aboutakong sure your dataset is “hygienic” and that you aren’t duplicating data points. A database is much different because it is less about representing data, and more about storing it in a way that allows you to perform transactions at scale - retrieval, storage, modification, etc. Relational databases are analyzed in terms of data cardinality which essentially describes tradeoffs in representation between speed of retrieval (duplications good) vs storage efficiency (duplications bad).

    The issue is that Elon is so vague and so off the mark that it is very hard to believe that he even has the first clue about what he is a talking about. Even you are confused just by reading it. It is all a tactic to convince others that he is smarter than he is while doing extreme damage to the hardworking people that actually make this stuff possible. Have you noticed that the man has never come to a conclusion that wasn’t in his interests? This is not honest intellectualism, or discussion based on technical merit. It’s self serving propaganda.







  • As someone explained in another comment, you often duplicate information due to rules around cardinality to gain improvements in retrieval an. structure. I would be pretty worried if SSSNs were being used as a a widepread primary key in any set of tables - those should generally be UUIDs that can be optimized for gashing while avoiding collisions.

    Even if we are being generous to Elon, we could assume that social security payments are processed on mainframes given how many have to go out and the legacy nature of the program. Most mainframe shops I know have adapted an SQL interface for records in some capacity, but who knows what he is looking at.

    Government federal IT is done at a per agency basis. I would say oracle database is pretty much the most licensed piece of software the government does use outside of Redhat Linux and windows desktop.




  • It’s an insanely idiotic thing to say. Federal government IT is myriad, and done at a per agency level. Any relational database system, which the federal government uses plenty of, uses SQL in one way or another. Elon doesn’t know what he is talking about at all, and is being an ultimate idiot about this. Even in the context of mainframe projects thatif we are giving elong the benefit of doubt about referring to, most COBOL shoprbibknow have adapted to addressing internal data records using an SQL interface, although obviously in that legacy world it is insanely fractured and arcane.



  • I asked this exact thing somewhere else, and the best answers I got were:

    • there is a somewhat legitimate motivation for fedora to package their own flatpaks in the context of their atomic desktops project.
    • they started doing this before flathub was established, and it was a better idea at that time.

    So, as per usual with Linux, there are some obscure and historical reasons this is a thing, but it is useless for the majority of users. Fedora should really not have it configured as the default source for flatpaks out of the box
