Today I Learned
What did you learn today? Share it with us!
We learn something new every day. This is a community dedicated to informing each other and helping to spread knowledge.
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 TIL. Linking to a source of info is optional, but highly recommended as it helps to spark discussion.
** Posts must be about an actual fact that you have learned, but it doesn't matter if you learned it today. See Rule 6 for all exceptions.**
Rule 2- Your post subject cannot be illegal or NSFW material.
Your post 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.
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-TIL posts.
Provided it is about the community itself, you may post non-TIL posts using the [META] tag on your post title.
Rule 7- You can't harass or disturb other members.
If you vocally 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.
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.

<Proceeds to dress as The Sea>
Its not the thread and would actually look okay (or, at least, not like you are a cosplaying goober) as clothing but
https://en.wikipedia.org/wiki/Ship_camouflage
It speaks to the actual role of camouflage as breaking up silhouettes. Which... if you are on the open sea is a major problem because there is nothing to blend into. Hence stuff like dazzle that is more about making it hard to distinguish exactly what kind of ship you are, what your direction is, or what your speed is. And it is genuinely wild how effective it was. Some of the more realistic WW1/2 naval milsims implement it and it makes you understand just how important radar/sonar actually was when you are struggling to make a firing solution for your torpedoes against what MIGHT be a destroyer.
It's ironic that they chose an example of dazzle for the article's main photo since it's purpose isn't to concealn disguise, or blend in so much as make ranging difficult. Not looking to split hairs with semantics. I just think it's cool.
https://en.m.wikipedia.org/wiki/Dazzle_camouflage
I mean... if you actually read the article (or even the comment you are replying to...) you'll see it isn't ironic in the slightest.
Camouflage from other ships really isn't a thing. You can paint your ship grey or blue but that still stands out against the horizon at sea probably 20 hours a day. And is worse than useless if you are near a shoreline.
Odds get a lot better against aerial spotters (e.g. planes) but that also has mostly been rendered pointless in an era of radar since you anti-radar paint is VERY expensive and you don't have many options to add the angles that actually make the biggest difference for stealth purposes.
Which is why Dazzle et al were generally the popular approach. You were going to see the ship no matter what, so the point is to make it as hard to get actionable data out of that visual contact as possible. And... once radar and sonar took over there wasn't even much point to that.
