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: Disiniformation, 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.

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



Partnered Communities:

"WHY": It can help you plan for the best places to sit, take photos, etc.


A friend is planning an event this summer and wanted to find a shady spot in a large park for people to sit. I remembered seeing this project, and it helped in my use case

Here is the website: https://shademap.app/

Here is the developer's GitHub with some code, API, and sample projects: https://github.com/ted-piotrowski

Here is an article I found by Bellingcat talking about the features: https://bellingcat.gitbook.io/toolkit/more/all-tools/shademap

There is also this other tool ShadowMap (app.shadowmap.org), but the data quality wasn't great for the places that I tried.

Pretty neat. Even gets the mountain shadows.

[–] lautre@jlai.lu 2 points 9 hours ago

I used the tool when looking for a house to buy.

I was looking in a mountainous area so the amount of sun a house gets in winter can vary quite a lot. Even a few hundred meters can make a huge difference in some cases.

I'll have to remember this one during the next storm

As someone that's a design engineer for the solar industry, this might actually be a useful tool for me! Thanks for putting it together!

As a design engineer you don't have CAD software that can predict shading? It's a pretty trivial function, actually. Also, you should know the procedure to construct proper shadows, but sure, that takes a lot more time than having them done by CAD.

[–] Resonosity@lemmy.dbzer0.com 10 points 10 hours ago

you don't have CAD

I do, but I'm an design engineer not a designer so my CAD skills are just basic. And I have better things to do with my time than learn CAD beyond the things I do now just to do what this tool does. My firm has designers that are better equipped for that kind of work, so there isn't really a need.

pretty trivial function

How so?

you should know the procedure

And you should know how to suck me from behind.

Shockingly accurate even for my unremarkable small town. It even has the tree shadows!

[–] popcorp@discuss.tchncs.de 8 points 19 hours ago

This is so amazing. And accurate. Thanks!

[–] 200ok@lemmy.world 19 points 1 day ago

Thank you!!!

I've been looking for a way to find out how much sunlight certain spots get at specific times of year.

Internet, today was a good day ❤️

Damned slick! Seems right on the money with my house, given variations for small landscaping changes.

This is really cool - thank you for sharing!
