!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.

What happened to cylindrical plugs? (lemmy.world)

Barrel jacks were awesome, they could go in any orientation. The only downside was the many different forms of barrel jack and lack of a standard. My question is: why isn't there a cylindrical USB port? You would be able to rotate it any way you want within 360 degrees!

As a matter of fact, why isn't there a cylindrical power plug? You'd get the benefits of a recessed plug like Type-C (EU) and Type-F (Schuko), you'd get the benefits of reversible plugs like Type-A (North American) and more so as you get 360-degree rotation, and it would be MUCH harder to break/bend compared to two flimsy pins (the UK plug has three thicker pins, but a chunky cylinder would be much more difficult to bend than the pins)

If it was a hollow cylinder (a bit like a vacuum-insulated water bottle), you could feasibly fit some small electronics in it, so things like flush low-power USB chargers and smart home sensors could be made.

The contacts would likely need to be outside the cylinder, similar to the "neutral" pins on Schuko plugs. There would likely need to be some plastic tabs to keep the power bits from touching the non-power bits, and then the socket itself would be able to freely rotate.

Actually, why don't regular sockets freely rotate? Then it would solve all the issues of non-reversible plugs not able to go upside down and reversible plugs not able to go sideways.

Speaking of cylindrical objects, what happened to camcorders? They sound like the most comfortable and easiest way to record videos, with straps and everything. They were compact, portable, and wasn't heavy as all heck.

this is my rant about cylinders, thank you for your time.

I saw that chart too. When you click on the F-type link you learn it's rated up to 4 GHz. The summary table is off for several connectors.

You cannot argue that the mating is poor if it's rated to 4 GHz.

There is nothing wrong with using the centre pin of the coax, it's one less join in the chain and it's rated at over 500 matings. It's not for lab equipment, but if you want to connect something and leave it there for the next decade, there's nothing better.
