I’m a tech interested guy. I’ve touched SQL once or twice, but wasn’t able to really make sense of it. That combined with not having a practical use leaves SQL as largely a black box in my mind (though I am somewhat familiar with technical concepts in databasing).
With that, I keep seeing [pic related] as proof that Elon Musk doesn’t understand SQL.
Can someone give me a technical explanation for how one would come to that conclusion? I’d love if you could pass technical documentation for that.
To be a bit more generic here, when you’re at government scale you’re generally deep in trade-off territory. Time and space are frequently opposed values and you have to choose which one is most important, and consider the expenses of both.
E.g. caching is duplicating data to save time. Without it we’d have lower storage costs, but longer wait times and more network traffic.
