YSK - for all the things that can make your life easier!

The rules for posting and commenting, besides the rules defined here for lemmy.world, are as follows:

Rules (interactive)


Rule 1- All posts must begin with YSK.

All posts must begin with YSK. If you're a Mastodon user, then include YSK after @youshouldknow. This is a community to share tips and tricks that will help you improve your life.



Rule 2- Your post body text must include the reason WHY YSK:

In your post's text body, you must include the reason "Why" YSK: It’s helpful for readability, and informs readers about the importance of the content.



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.

Posts and comments 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 non-YSK posts.

Provided it is about the community itself, you may post non-YSK posts using the [META] tag on your post title.



Rule 7- You can't harass or disturb other members.

If you harass or discriminate against any individual member, you will be removed.

If you are a member, sympathizer 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.

For further explanation, clarification and feedback about this rule, you may follow this link.



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- The majority of bots aren't allowed to participate here.

Unless included in our Whitelist for Bots, your bot will not be allowed to participate in this community. To have your bot whitelisted, please contact the moderators for a short review.



Rule 11- Posts must actually be true:

Disinformation, trolling, and being misleading will not be tolerated. Repeated or egregious attempts will earn you a ban. This also applies to filing reports: If you continually file false reports YOU WILL BE BANNED! We can see who reports what, and shenanigans will not be tolerated. We are not here to ban people who said something you don't like.



Rule 12- Linking directly to a video as a source is not acceptable.

Video only posts are responsible for an outsized portion of rules violations. Your post must contain text and meet the requirements of the previous rules.



Rule 13- If you file a report, include what specific rule is being violated and how.

Just learned about the Kaprun disaster in which 155 people lost their lives when an underground train caught fire.

There were only 12 survivors all of whom followed the advice of a retired firefighter who advised them to run downhill through the flames in the rear of the train.

The steep incline of the tunnel acted as a blast furnace that sucked in fresh air from the low end and funneled toxic smoke to the high end.

Not sure how applicable this will be to anyone here, but I thought it a great example of how a little more widespread knowledge of how fire works could have saved a lot of lives.

Tl;dr fire bad but smoke worse. Get to fresh air.

So it’s really about getting under the fire, even if that means going through it first.

[–] notabot@piefed.social 8 points 4 days ago

Specifically, you want to be up wind of the fire, and it the fire is creating that wind in an inclined tunnel that might involve heading down, through the fire. Funicular railways and stairwells could both be places that's necessary.

No. Structures on fire tend to collapse, and then you have fire falling onto you. That sounds like a bad idea.

[–] Bbbbbbbbbbb@lemmy.world 9 points 4 days ago (1 children)

It may either be that or waiting at the top of a burning structure thats going to collapse?

once you get to the top of the structure, evolve some kind of hot air balloon to float to safety.

Actually yes. The thing is that falling onto the fire isn’t any better than the fire falling onto you. You always want to be below where the fire is because that’s where the fresh cool air is, and where the heat and smoke is not.

[–] EncryptKeeper@lemmy.world 1 points 4 days ago

I mean you don’t want to go through it, that will just kill you. But staying below the heat and smoke it’s generating is always a good idea.
