Like, why wouldn’t people be interested in knowing that the African slave trade of the colonial period actually started with Jewish kids, but they all died in the African climate of Sao Tome, so the Portuguese started buying slaves from the Congolese, which they captured from neighboring tribes, to work the fields??
Please tell me more about tasker and the subnautica GPS!
I wrote about it on that other website a couple years ago, I’ll link to archives of my posts there
Here’s what I submitted to the Subnautica forum
Here’s what I submitted to the Tasker forum
Tasker is an Android application that lets you automate many different things. One of its features is setting variables for use in your tasks–for example, I have a task sets the variable %Wallpaper to a random number between 1 and 152, and sets my phone wallpaper to DCIM/Backgrounds/%Wallpaper.png every time I turn on my screen, because I don’t want to stay married to one specific wallpaper
You can also do math with variables, which allowed me to program the trilateration algorithm on this webpage into Tasker. All you need to input is your current depth, and your distance to each of three specific landmarks (oceanmarks?), and it’ll do all the complicated squaring and adding and subtracting for you, and then give you a notification with your approximate coordinates–in testing, it’s usually accurate to within about 10 meters, which is more than accurate enough for us to see whatever we’re looking for.
I wish I could actually understand why the squaring and adding and subtracting gives you accurate coordinates, but you don’t got to know what baking powder does to make good bread, you just gotta follow the recipe!
You’ve got me curious about this now too lol. I work with games and love this kind of thing. I’ll know more once I’m not trying to do research on a phone, but the squaring part looks like just a distance formula (A^2 + B^2 = C^2). My very rough guess with the subtracting and adding is you’re basically doing vector math but I’m unsure. I can respond or edit later as I find out more.
Do you mean Pythagoras theorem?
I know what the Pythagorean theorem is, I implemented it in the program to account for differences in depth because trilateration with three known points only works in 2 dimensions.
It’s stuff like this

That I can’t quite wrap my head around
