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.

They're like that in this apartment we're renting and I keep seeing them elsewhere. I don't get it.

I expected Technology Connections or ElectroBOOM, was not disappointed.

To turn things on and off.

Massive if correct

I remember when I was young and bending down all the time was a thing you could do painlessly. Ah, youth.

[–] [email protected] 5 points 9 hours ago

I can still bend down ok, but getting back up off my knees however….

Smart plugs are awesome!

[–] [email protected] 8 points 9 hours ago* (last edited 9 hours ago) (2 children)

also small child/baby protection.

[–] [email protected] 8 points 6 hours ago

But who will protect the big babies?

[–] [email protected] 5 points 6 hours ago (1 children)

How does the switch protect children?

[–] [email protected] 2 points 4 hours ago

if it is a small child it is assumed that the joint probability of both turning on the switch and inserting a fork through the holes is roughly the product of probabilities of each (therefore lower than each individually), i.e both events are independent.

UK household electricity is pretty spicy compared to many other places - it has more safety features as a result. (3 pinned fused plug, socket switches etc)

[–] [email protected] 19 points 11 hours ago

Isn't it just 230v 50 Hz like most of the world?

Apparently around 65-70 % of the world population (with access to electricity) has 230v 50 Hz.

[–] [email protected] 10 points 11 hours ago (1 children)

How is it more "spicy" than anywhere else in Europe?

In our defence, most of that is legacy from the post war rebuild (copper shortages etc). The modern regs are comparable or better than a lot of places.

There's enough of the dodgy stuff around that it needs to be accounted for, but it's being phased out as new stuff it built or renovated.

[–] [email protected] 3 points 9 hours ago* (last edited 9 hours ago) (1 children)

Do they have the wiring on the outside of the houses so it's easier to repair?
I've heard in UK they tend to do such things.

[–] [email protected] 2 points 7 hours ago* (last edited 7 hours ago) (1 children)

No, it's usually buried in the wall behind the plasterboard. Although it is possible to use surface trunking. It's quicker and therefore cheaper to use trunking with less making good afterwards

[–] [email protected] 3 points 7 hours ago* (last edited 7 hours ago) (1 children)

It was a joke on UK putting water pipes on the outside of their houses.
Making them sometimes freeze and burst in the winter, but it's easier to repair. 😋

[–] [email protected] 2 points 2 hours ago (1 children)

Well duh, they freeze and burst in winter so they obviously need to be outside for easier repair! Think of the mess they would make if they were inside the walls.

[–] [email protected] 1 points 2 hours ago

Absolutely, it's not the UK that are crazy, it's everybody else.

[–] [email protected] 4 points 10 hours ago (2 children)

when any electricity leaks out (for example through your body) it switches off. the eu also has the same system, but its one switch for your entire house. the us also has this but only in bathrooms.

[–] prettybunnys 6 points 8 hours ago

GFCI circuits are required by code around sinks and the like. Bathrooms, kitchens, utility wet rooms, etc.

You can relatively easily install them anywhere you want though.

[–] [email protected] 8 points 10 hours ago (1 children)

These aren't automatic switches, but other people explained the reasoning.

[–] [email protected] 4 points 10 hours ago (1 children)

oh, according to electroboom they were gfci.

[–] [email protected] 5 points 9 hours ago

They're connected to an RCD, as modern UK wiring has all sockets connected via an overall RCD in the fusebox, but the switches on the socket are just basic on/off switches.
