Accurate geolocation (luna-location? seleno-location?) remains a hard problem on the Moon, and makes Terrain Relative Navigation a non-trivial task to this day.

I present here Galatea, a fused Visual Place Recognition model that can make existing models perform closer to terrestrial models levels of accuracy on extra-terrestrial surfaces.

Very interesting visualization approach. I think I'll try to do this with NOAA's bathymetric data and NASA's Lunar LOLA DEM.

The Sierpinski triangle was the first "complex" system I had managed to draw, using the Logo programming language in the 90s. I recently tried to do a vtk 3D extension (Sierpinski cube)[1] using the same process as in the OP, but it was surprisingly computationally expensive!

I'm actually very interested in the Delay/Disruption Tolerant Networking protocol that is under development at Goddard. I've found a lot of resources on why it is needed and how it is helpful, but not much on the actual implementation.

Where is vectored I/O used in practice? I'd think the requirement of using multiple buffers for scatter/gather is not very efficient...

That ship in their example,the Seneca (Bark) of New Bedford, Mass., has a super interesting history: https://archive.org/details/logbookofsenecab00unse

For some reason that feels like cheating on a test but it's brilliant nevertheless. I think I'll try it with the 15 local corner shop sites that I'm hosting out of the goodness of my heart. Thanks!

I love it! A minor question: is there any way to have profiles, so to speak, so that I can switch between official and 'casual' online identities?
