OK, so I’ve given up on restoring my previous Windows guest machine, and am going to create a new one (I only lost a couple files that I cared about). But now VB won’t work properly. Without getting into detail on the error messages, I’d like to just completely remove it, and do a clean install. But I can’t figure out how to do it.
I apparently installed it from a script, so there are no Fedora packages for it, so dnf can’t do anything. When I click on the details of the icon in Gnome, and select remove, it just shrugs its digital shoulders. Anyone have any suggestions?
It didn’t make much sense even at the beginning, give that we knew early on that UV killed it, and there was no evidence of transmission under those circumstances, but it’s come to the point at which it’s now just stupid.
I met Dr. Bhattacharya in October, shortly after the declaration was drafted, at the Hillsdale event where I gave my presentation on the economics of space.
SpaceX is throwing in the towel on fairing recovery, at least in terms of catching them.
There is always a tradeoff between reusability and expendability in terms of minimizing cost per flight. Shuttle had some notoriously bad design decisions, because they anticipated a higher flight rate than they ever got. At the end of the program, it was clear that it would have been cheaper to expend the SRBs than to recover and refurbish them, because of the high fixed costs of the recovery fleet that had to be amortized over a low flight rate. Expending the ET cost tens of millions per flight.
Elon was determined early on to recover as much of the vehicle as possible (they spent years trying to figure out how to recover the upper stage of the Falcon), but he finally decided that the only solution was to scale the vehicle up, and go to stainless steel to handle entry heating, so the focus is on Starship now, and Falcon 9 has reached the end of its development cycle.
Between this kind of thing and the vaccines, I think this is all over but the shouting. I am definitely done with wearing a mask outside, especially in sunlight. Masks outside never made any scientific sense.

Popular new mask says “I’m not a Democrat; I just forgot to take off my mask when I left the store.”
All these leftist institutions–government schools, academia, Hollywood, the media, the Democrat-run cities–should be thoroughly kicked while they’re down, and keep them down.
I think this is a message to Congress that if they want to increase the amount of money NASA has to waste on Artemis, they’re going to have to increase the budget.
I haven’t read it yet, but I wonder if the fact that SpaceX can takeoff and land with minimal blasting of regolith, with its engines so high on the vehicle, was a significant factor?

Glancing through it, ouch. Dynetics Technical Rating was “Marginal.” For the highest bid…
