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.

I recently saw a comment chain about nuclear bombs, and that led me to thinking about this. Say there is a nuclear explosion in the downtown of my US city. I survive relatively fine, but obviously the main part of the city has been destroyed, while major zones extending from the center were also badly damaged. What would be a good response to (a) survive and (b) help out the recovery effort?

This brings to mind something David Mitchell said once on Would I Lie To You (British panel show):

In response to Kelvin MacKenzie's claim that the "This Is My" guest had built him a nuclear bunker:

David Mitchell: If there's a nuclear war, I don't want to live. I don't want to come out of a shelter and try to rebuild society. I have no skills. Okay, society is destroyed by a nuclear war, we're basically - we're back to the bronze age...how long is it gonna be before people start pitching panel shows again? It's gonna be at least 2000 years!

Watch it here if you want, it was annoyingly hard to find.

However I don't think David - who is a comedian - is precisely right about how such a war would affect the state of technology. If there are survivors, I don't think we'd really be back to the bronze age. Even if all technology was destroyed (which it wouldn't be), give humans a few decades, we'll have some sort of modern technology back up and running. Maybe not computers, but some certainly some analogue electronics - the knowledge isn't lost. Communications would be one of the first points of focus, so television would follow closely behind.

The longest stretch would likely be chip fabs. You need precision electronics and hazardous chemicals and plenty of power.

But considering that some form of electronics will survive, and it wouldnt take long for people to get rudimentary electricity going, I don't see why we couldn't have world Internet within a decade.

[–] NeatNit@discuss.tchncs.de 4 points 4 months ago (2 children)

Yeah, chip fabs are exactly why I think computers would need more time. I'm not super familiar with this, but I'd wager such a factory can only be built using tools and machines that come from other specialized factories, and so on maybe 3 levels down before you get to a relatively rudimentary manufacturing process that can be reasonably achieved within a few years. It would take a lot to get that back up and running.

[–] Zoot@reddthat.com 3 points 4 months ago (1 children)

However... Just think about how many chips are currently just sitting around... Between scrapping and searching you would likely be just fine for a few decades.

[–] Mammothmothman@lemmy.ca 1 points 4 months ago (1 children)

EMP would fry most of them though.

[–] Zoot@reddthat.com 1 points 4 months ago

Only if they were currently running, and I'm willing to guess the vast majority of reusable/scrap chips will be unpowered in the event of an EMP.

Replacing all working electronics with new boards would definitely be a task. But unless we get an massive flare from the sun I hardly think that'll be an issue.

[–] intensely_human@lemm.ee 1 points 3 months ago (1 children)

By the time nuclear war happens, most chip manufacturing capability will be underground or in hidden sites and therefore not targeted.

[–] NeatNit@discuss.tchncs.de 1 points 3 months ago

How could you be sure of any of that? For all we know, nuclear war could start tomorrow. Or, a bit more realistically, next year. How fast can these factories be built?
