There's a good account in the Mike Mullane book "Riding Rockets"

@ErinAnne I'm not claiming they could never be useful but just that the utility seems limited. On the STS-41D pad abort there was a hydrogen fire that (stories differ) could have burned the crew if they had tried to use the escape system.

@ErinAnne Always seemed to me that all those methods (slidewaire, slides) rely on a pretty slow disaster happening.

@ErinAnne Pretty much the standard opening for shuttle Post Insertion and Deorbit Prep intro classes was "Today you will learn how to convert your rocket ship into a space station".... / "Today you will learn how to convert your space station into a hypersonic glider..."

@ymb1 thanks! I actually deleted it myself, because I saw that note about self registration. When I get on a real computer, I'll give it a try. Looks like a great document.

See, that is different. No -. Please edit your question and show the actual command you ran.
Oct 6, 2024 19:18
The command in that other answer requires you to type -name explicitly. You replaced it with -CapCut which as others have commented will just error off. What you think happened, did not happen. Use the command history in a terminal to see what you actually did. That other answer also tells you to run it without the -delete first!

And following on from @muru's comment, that the keys were copied to the directory of the correct user. As far as the log goes, when I do it, I don't get the "next authentication method" line in my log for the public key attempt. Did it try some other method first? Could be a version difference, my server is 20.04.

Check for the existence of /etc/ssh/sshd_config.d/50-cloud-init.conf and see if it contains a line that enables password login. From askubuntu.com/q/1494410/243321
 
May 20, 2024 00:06
I am glad it worked! I will write an answer and do some explaining. You can accept it if you like once I am done.
May 20, 2024 00:06
@user628388 great minds, I asked that an hour ago. Diegonu, If you unmounted the NAS and got no change in the size, then you have data written to that mountpoint in error. Unmount the NAS and delete whatever is in that mountpoint. BUT MAKE SURE THE NAS IS REALLY UNMOUNTED I'd power it off to make sure
May 20, 2024 00:06
I wonder if you wrote a bunch of data to that mountpoint incorrectly thinking it was to the NAS. Remove/unmount the NAS and see if that directory is still huge.

I haven't voted on this question at all, and I despise Musk (and have since before despising him was cool), but your question as written asks "why not" Musk didn't pick a different metric instead of inventing this one. Not answerable. Possibly salvageable by revision.
May 17, 2024 11:52
You mean, like calling something idiotic?
May 17, 2024 11:52
Even if it was space related, it's asking for opinions.
 
Mar 4, 2024 16:24
@DaviSN what is "the same error"? Put the info in your question. I'm done for the night.
Mar 4, 2024 16:24
@ubfan1 the message seemed pretty explicit. And see comments on mchid's answer. 'The 470 driver will ignore this GPU" does not leave much wiggle room.
Mar 4, 2024 16:24
So, you don;t know how to choose a kernel at the grub screen? I am asking so I know how detailed to be. Have you ever done it?
Mar 4, 2024 16:24
Do you know how to boot into different kernels using the grub screen? I am asking so I know how detailed to be.
Mar 4, 2024 16:24
You can boot into the GA kernel using the grub screen at powerup. If it works for you, I would then delete the linux-generic-hwe-20.04 package and all its buddies.
Mar 4, 2024 16:24
@ubfan1 You got me curious so I installed the HWE kernel and the 470 driver. It installed ok, so I was pretty happy...but when I rebooted, a black screen came up before the login screen with the text "The Nvidia GeForce GT 730 GPU in this system is supported through the 390 legacy driver...The 470 driver will ignore this GPU" and it came up using nouveau. So it's pretty clear that driver doesn't support the GT 730 - it told me so!
Mar 4, 2024 16:24
@ubfan1 perhaps one needs the HWE kernel series for that driver. I see the packages in the repos, but since "additional drivers" does not offer it up for my current configuration, I doubt it would work. If I can find some time tomorrow I'll clonezilla my system, try installing the hwe kernel, and see if it's offered up and will install.
Mar 4, 2024 16:24
@ubfan1 when I go to "additional drivers" it does not offer up a 470 driver, only 340 and 390. Are you asking about a 22.04 install? I have 20.04 right now.
Mar 4, 2024 16:24
@DaviSN 1) Don't use the answer button to post comments. 2) In an 20.04 install, do an apt policy linux-generic, if that shows 5.4.0-172-generic then install linux-generic and the packages that it pulls in. Then boot into that kernel using the grub menu and uninstall the hwe kernel and its related packages.
Mar 4, 2024 16:24
@DaviSN As you can see from the printouts I included in the answer, I have the 340 driver working on 20.04 with the GA kernel.
 
Mar 2, 2024 22:36
What version of Ubuntu is this?
 
Feb 10, 2024 21:54
Exactly what did you do when "trying to repair" that package?
 
Dec 30, 2023 00:31
It is unclear what you are asking. You seem to have repeatedly changed the meaning of the question
 
Dec 16, 2023 06:13
Please edit your question and list the "10 picks". Then someone can tell you which one to choose.
 
Oct 9, 2023 17:32
In other words, you have spend billions of dollars in fixed cost and millions more in propellant to gain 100 km/h, which a decent used car will get you for a lot less.
Oct 9, 2023 17:32
If your tower is 400 km tall (ISS altitude) and it's built on the equator its tip will be moving 1780 km/h in round numbers (about 100 km/h faster than the surface of the Earfh). ISS orbital speed is 28,000 km/h in round numbers. Your tower is useless as an orbital launcher.
Oct 9, 2023 17:32
All other considerations (and there are a lot) aside, this tower will be useless as a launcher because its tip (at LEO) will not be in orbit. It's just a tall building. Release something from it...the something falls.
 
Jul 19, 2023 16:41
One question per post, please. Please do some prior research too. The answer to your #3, for example, is obvious.
 
Jul 17, 2023 17:34
Thanks for including the internet archive link in your question, thus solidly confirming that you are a Moon-hoaxer. You must have really worked hard to dig that one up, and what an utterly pathetic bit of support for your cause it is. Surely you have better things to do than tilt at the Moon-hoaxing windmill on this site.
Jul 17, 2023 17:34
I have no intention of reading some link to see what point you're trying to make. Also, what is "the moon landing"? There have been a few.
Jul 17, 2023 17:34
There is no such unicorn as a cheap amateur balloonborne X-ray telescope.

Aft is aft and forward is forward. It doesn't matter where the observer is. By your logic the nose becomes the tail depending on which direction you are looking. Spoiler alert: it doesn't. Downvoted till this is corrected.
 
Apr 30, 2023 14:00
@RonJohn sure, it worked out great.
Apr 30, 2023 14:00
@RonJohn seemingly unproven at this point.
Apr 30, 2023 14:00
I would say that multiple engines out during first stage means it didn't go normally.
 
Apr 4, 2023 17:58
Thanks, but looks like that isn't the culprit. Way down in your output I see muon. You don't necessarily need to add the output of apt policy muon unless you run it and see a nonstandard source.
Apr 4, 2023 17:58
How about doing an apt policy software-properties-qt and adding the output to the question? That command shows the different versions of a package available to your system and where they came from. This kind of problem usually results from having added a problematic source to your system, and that command can help track it down.
 
Mar 31, 2023 16:47
What kind of power supply were you envisioning?
 
Mar 20, 2023 10:32
That is a false dichotomy.
Mar 20, 2023 10:32
I'm afraid the problems with this idea go back to the rocket equation, which you struggled with before.
Mar 20, 2023 10:32
So the idea is, carry up solid boosters, with their poor Isp, instead of carrying up liquid fuel, with its good Isp?
Mar 20, 2023 10:32
Do you mean "expendable" perhaps?
Mar 20, 2023 10:32
What, exactly, is an "expandable solid fuel booster"?
 
Mar 8, 2023 20:05
@uhoh This paper suggests that a better lift coefficient might be no higher than 0.4, but that just makes it worse by cutting the wing loading even more. ntrs.nasa.gov/archive/nasa/casi.ntrs.nasa.gov/19710010231.pd‌​f
