No such thing. Ask away!
!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:
Rules (interactive)
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.

Its because the comments he made are inconsistent with common conventions in data engineering.
Basically what he said is ~~incoherent~~ inconsistent with typical practices among data engineers ~~to anybody who has worked with larger data.~~
In terms of using SQL, it's basically just a more reliable and better Excel that doesn't come with a default GUI.
If you need to store data, It's almost always best throw it into a SQLite database Because it keeps it structured. It's standardised and it can be used from any programming language.
However, many people use excel because they don't have experience with programming languages.
Get chatGpt to help you write a PyQT GUI for a SQLite database and I think you would develop a high level understanding for how the pieces fit together
Edit: @zalgotext made a good point.
Great explanation, but I have a tiny, tiny, minor nit-pick
I'm being pedantic, but I disagree with your wording. As a backend dev, I work with relational databases a ton, and what Musk said wasn't incomprehensible to me, it just sounded like something a first year engineer fresh out of college would say.
Again, the rest of your explanation is spot on, absolutely no notes, but I do think the distinction between "adult making up incomprehensible bullshit" and "adult cosplaying as a baby engineer who thinks he's hot shit but doesn't know anything beyond surface level stuff" is important.
Fair point, I've edited the answer to be clearer for future readers.
That's a bad example to reference. The ZFS implementation of deduplication is poorly thought out, and I say that even though I like and run ZFS on my own Linux server(s). I understand that the BTRFS implementation of dedupe works well (no first-hand experience), and the Windows one works great (first-hand experience).
I've had a poor experience with btrfs dedupe tbh (and a terrible experience with qgroups), however, this was years ago. Btrfs snapshots I prefer though, much easier not to have that dependence.
What distro are you using for ZFS, void?
Good to know, thanks. I haven't worked with btrfs much yet. I have ZFS on a Debian server.
