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.

Bravo! Outstanding explanation. I got lost on like the second sentence though. If you have the time, can you also ELI5
It's a common enough expression but what does it even mean?
This is it. This is the comment that makes me realize that I'm old.
Wow, this caught me off guard. I read an article about kids being given old tech and they knew people waved Polaroids (even though it doesn’t enhance development) from pop culture. Are young people really unaware that we used to dial with a modem to connect to the net?
No I meant do analog modems use tones to transmit information, or how does it work?
Like what is the process of "dial with a modem to connect to the net".
Modem is short for modulator/demodulator. It took a data stream and encoded it onto tones, multiple (audible) frequencies were used to increase data rates. You had to dial in to either a server, another computer, or an ISP. If you picked up the phone you would hear what sounded like white noise.
I lost many a download, or 'online' game to my mother picking up the phone to make a phone call.
That's very clear, thanks. I remember reading about the original phreakers, one guy had perfect pitch so he could just sing the tone to open a long distance line and then dial away. I think he got sued by one of the American phone companies for stealing.
There are some amazing stories about the cat and mouse games regarding phone phreaking. The "captain crunch whistle" is great. All their attempts at security, beaten by a bit of audible brute force, via a cereal box toy.
Think of it like a "fast", automated telegraph that speaks in audible binary instead of Morse code.
Thanks yea, that's exactly what I was wondering.
It might actually be hexadecimal or some other encoding but you get the point.
Watch Wargames. The main character uses the Ethernet somewhat realistically compared to more modern "depictions" of "hackers," and has to use an absolutely ancient modem to connect to the network.
Omg "a 1983 American techno-thriller film"... sounds awesome B-)
And probably more relevant today than it was back then.
That I can help. Back in the day, to access someone’s else computer you literally hooked up yours to a phone line. Your desktop would then dial to some number you got that had another computer listening to answer, and they would start a “conversation”. Your computer sent what to us would sound like noise, the receiving computer would listen to that noise and answer back. Voilá, you’re connected to a network!
This is how it sounded like
And here’s an explanation about what’s happening.
It's binary with low tones representing 0 and high tones representing 1. Thanks for the link, that's just what I wanted to know!
