Crew Or Automated
An interesting thread:
Will the flight crew get to “drive” Starship HLS during terminal landing on the Moon, or will landing be fully automated? The idea of a pilot landing something so tall and massive by hand on rough terrain seems a little… difficult? But if there’s no crew in the loop, how will… pic.twitter.com/338ApLPcLx

Linux Update Problem
When I ‘dnf -y update’ it downloads all the packages, but at the end crashes with this error message:
Importing OpenPGP key 0x7FAC5991:

Any idea how to tell it to ignore this and just do the other updates? I don’t see any obvious options on “dnf update.”
Thanks for the advice in comments. Unfortunately, I can’t deal with it until I get back from a trip on Friday.
[Friday update]
The problem seems to have resolved itself while I was gone. I updated last night with no issues.
Cameras Versus Lidar/Radar
Why Elon dropped lidar for FSD.
The reason why Tesla FSD performs better with just computer vision than systems that have LIDAR and radar is a bit counter intuitive. Allow me to try to explain.

It’s not obvious that this professor of aerospace engineering knows that the sun is the hardest place to get to in the solar system. Escape from the solar system is easier.
