!nostupidquestions is a community dedicated to being helpful and answering each others' questions on various topics.
The rules for posting and commenting, besides the rules defined here for lemmy.world, are as follows:
Rule 1- All posts must be legitimate questions. All post titles must include a question.
All posts must be legitimate questions, and all post titles must include a question. Questions that are joke or trolling questions, memes, song lyrics as title, etc. are not allowed here. See Rule 6 for all exceptions.
Rule 2- Your question subject cannot be illegal or NSFW material.
Your question subject cannot be illegal or NSFW material. You will be warned first, banned second.
Rule 3- Do not seek mental, medical and professional help here.
Do not seek mental, medical and professional help here. Breaking this rule will not get you or your post removed, but it will put you at risk, and possibly in danger.
Rule 4- No self promotion or upvote-farming of any kind.
That's it.
Rule 5- No baiting or sealioning or promoting an agenda.
Questions which, instead of being of an innocuous nature, are specifically intended (based on reports and in the opinion of our crack moderation team) to bait users into ideological wars on charged political topics will be removed and the authors warned - or banned - depending on severity.
Rule 6- Regarding META posts and joke questions.
Provided it is about the community itself, you may post non-question posts using the [META] tag on your post title.
On fridays, you are allowed to post meme and troll questions, on the condition that it's in text format only, and conforms with our other rules. These posts MUST include the [NSQ Friday] tag in their title.
If you post a serious question on friday and are looking only for legitimate answers, then please include the [Serious] tag on your post. Irrelevant replies will then be removed by moderators.
Rule 7- You can't intentionally annoy, mock, or harass other members.
If you intentionally annoy, mock, harass, or discriminate against any individual member, you will be removed.
Likewise, if you are a member, sympathiser or a resemblant of a movement that is known to largely hate, mock, discriminate against, and/or want to take lives of a group of people, and you were provably vocal about your hate, then you will be banned on sight.
Rule 8- All comments should try to stay relevant to their parent content.
Rule 9- Reposts from other platforms are not allowed.
Let everyone have their own content.
Rule 10- Majority of bots aren't allowed to participate here.

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.
Musk canceled the support for the long running Common Education Data Standards (CEDS) which is an initiative to promote better database standards and normalization for the states to address this kind of thing.
It does not fucking matter if he is technically correct about one tiny detail because he is only using to to destroy, not to improve efficiency.
I mean it matters here, as it's literally the topic being actively discussed by the person who literally asked, so obviously it matters to them lol
The thing is, there are a large number of different reasons to store an SSN as a long int or a string depending on how it is used with the rest of the data. For a phone number, there can be a valid reason to store the area code separately to speed up data queries that narrow down by area code instead of all in one field and peeling it apart. There are also reasons to have additional, seemingly redundant, columns that can be used for optimizing searches or simplifying how queries are written.
A common one is that using 1 and 0 instead of Y an N is often faster for massively large dataset optimization, but isn't as easily human readable.
There are complex reasons for choosing different approaches in a database, and the most important thing is generally consistency within the database. His point is meaningless without context beyond consistency, and the different government systems will have had different priorities, not to mention trying to update all of the databases to make them consistent is a MASSIVE fucking undertaking. And the systems can stay the way they are as long as they have APIs or other methods of transferring data that ARE normalized and consistent.
I have personally been working with reporting data to federal systems for 15 years as a semi knowledgeable technical person. This is what I do for a job. What he is saying is pointlessly small trivia used to justify tearing things down instead of improving them.
They weren't justifying anything or making a moral statement, they were just discussing the technical question that was posed.
