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.

The yellow arrow points to a leather cord tied similar to a poacher's knot to have an end loop.

The red arrow are ends of an elastic string which passes through a hole (one for each end) in the leather.

I need to tie the elastic string ends in such a way to secure both the leather cord, and on itself so that when the elastic is pulled, it will not stretch. Also it should be hard but not impossible to untie.

Also it should not be too bulky.

It’s a standard figure 8 knot, but the end of the rope doubles back through the eight. This leaves the end of the 8 at the top of the knot & would look similar to this:

The right one looks easier to undo than a bowline.

I get you on that, it doesn’t look like much. I’m guessing that’s because it’s a true follow through & looks “traceable”?

Physics or whatnot means the stress that knot puts on itself allows it to retain roughly 80% of the ropes strength, without a backup knot.

Many use a backup knot, but that’s typically just for convenience, to get the loose end out of the way.

The biggest reason, aside from the knot’s strength (…and to my knowledge), that it is used for climbing, is because it will not fail or slip past a rope delivery system, such as an ATC or a grigri.

Basically if you’re ass backwards & heading in the wrong direction, that knot may help stop your decent by not blowing past a safety measure.

I think I made an unclear comment, lol. I actually meant it in a good way. It looks like a strong knot that holds up until it's time to take it apart, in which case it would be somewhar easier than a bowline.
