No Stupid Questions
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. This includes using AI responses and summaries.

Because it used to matter more. As other have said "ftp.domain.extension" was for FTP, mail for mail, and www for websites but that has long been somewhat redundant, as the servers at a domain redirect connections to the right place. mail.domain.extension was originally exclusively for mail servers themselves, but lots of websites long ago made it also valid for landing pages for web interfaces for their mail service if a request comes in via http.
WWW was certainly a very useful concept when people were getting used to the internet. A lot of people had no concept of computers and domains, so to say "www.domain.extension" was clear to people "this is the website for your browser". And when you say www it's very clear you're telling someone it's a website; that is helpful when say your audience my include elderly people who never got used to computers.
Also the redirection of connections is so simple now, that specifying WWW is generally just not needed. WWW is still the basic landing place for many web sites, but if you don't include it the servers at the domain will very likely direct you on to the right place, and if they don't your browser will often try again by appending www anyway and retrying to see if it reaches a valid webpage. So now we just don't need to tell people "you need to include www".
About when did this happen?
That's a question that probably requires more digging than I want to do.
On the DNS side, it depends on CNAME record types. Sources in the Wikipedia article suggest that was defined in 1987 and updated in 1997.
On the server side, it depends on how easily the server software can be configured to use multiple domains for the same site (or how easy it is to set up a redirect). This sounds like a deep home to research, and I'm not going to bother. But cPanel and Webmin are both about 30 years old now.
Could also be the amount of processing time strings take.
