That’s a super interesting project. For anyone else, the project overview has some great system level diagrams:

time for some kind of anonymizing location data sharing service, peer to peer or federated protocol? that might be interesting, or sketchy, not sure which.

Pretty sure you can download the maps ahead of time, GPS doesn’t require data, then upload the fixes when you get home.

Go map keeps crashing for me, does it for you?

I’ve been using Go Map! but it keeps crashing… Maybe I’ll try Streetcomplete if it’s on apple.

Crawling and indexing lemmy inter-instance would be an incredible boon to discoverability on the platform.

It’s beautiful!

The internet is a series of tubes.

Thanks, I fixed it

You’re getting it.

I’ve never tried Usenet, but I’ve heard little bits about it here and there. What’s a good way to give it a try?

Oh, maybe there wasn’t. I added it.

Yes! [email protected]

Oh, I see what you mean by

Is that… 32 bytes of memory?

No, each wire that goes through the rope, weaving through or around each of the ferrite rings, represents one or multiple bytes.

I totally want to try, I think ferrite toroids are everywhere, but the material that core/rope memory rings are made of has a specific magnetic response hysteresis which is important.

Oh, my bad, I linked the wrong page!, edited to include both

The touching of the cores isn’t really important, what matter is which specific wires run through each core vs around/outside each core. That weave pattern defines the addressing scheme and the data stored in each address.

I’ve idolized the pdp-8, and always wanted to lay my hands on one.

And rope memory!

Very good introduction to this topic.
