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

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.
About That Falcon 9 Booster Loss
It was caused by a fuel leak.
Leaks happen.
Utterly Compelling Historical Research

Tardigrades To The Rescue?
This seems very promising for both spaceflight and cancer treatment, if true.
incredible breakthrough: a protein from tardigrades can now protect human cells from radiation.

The launch webcast will go live ~40 minutes ahead of liftoff https://t.co/Q9HTUSYmtf
[Evening update]
Better luck tomorrow, or if they can’t turn it around that fast, Wednesday. Weather looks better, anyway.
Congrats To Firefly
It’s the first successful landing on the Moon of a private company.
But Max Polyakov was screwed over by the Deep State.
Next up: The next flight of Starship/SH tomorrow afternoon.
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.
