I was trying to find out whether it was stated somewhere which versions returned a view, and which returned a copy, but I just got a headache.
@StephenKitt Yes, I realise that. I mean, I thought that originally. Then I realised there were other two letter commands which were not builtins (of course). Are non-builtins referred to as executables? Or something else?
Here is another unfortunate user who was also confused about it.
I'm confused about the rules Pandas uses when deciding that a selection from a dataframe is a copy of the original dataframe, or a view on the original.
If I have, for example,
df = pd.DataFrame(np.random.randn(8,8), columns=list('ABCDEFGH'), index=range(1,9))
I understand that a query return...
@FaheemMitha in POSIX terminology, they’re all utilities; built-in utilities are identified as such, everything else isn’t, and built-in utilities are also supposed to exist as executables
Do we have consensus on whether to represent keyboard letters always as uppercase characters? I found this latest edit, by @AdminBee, confusing in this regard and would like to revert it. Maybe I should take it to Meta?
I’m not sure I’m entirely consistent with my keyboard edits, but I’d rather indicate the actual case in the key... I also have a keyboard somewhere which is labeled in lower case.
But this would be better discussed on Meta, yes, especially if the goal is to establish a ground rule.
@Quasímodo Personally (there is no policy on this I am aware of, so I'm just speaking as a regular user) I think we should always use lower case unless we actually need upper case. It is simply less ambiguous: i) if you use a capital letter for something like Ctrl+A it might be misinterpreted as Ctrl+(Shift+A) and ii) upper case I can be confused while i cannot. Conversely, lower case l (L) can be confused.... so maybe this isn't a very good point.
And having written this, I realize that I have never seen Ctrl+a and always see Ctrl+A. So maybe none of my points are very good.
In such circumstances, script is very handy: it runs a shell, recording all the output. In your example, before entering the chroot you'd run
script temp_file.txt
and then
sudo enter-chroot
etc. On exit from the chroot, you'd exit again to exit script, and you'd find the text you wanted (al...
Another choice:
Ctrl+W : Delete everything till the first white space, basically, delete the last word.
Genrally useful shortcuts (don't work for password prompts):
Ctrl+A : Go to the beginning of the line
Ctrl+E : Go to the end of the line
Ctrl+K : Kill everything from the position of the...
And that is actually ambiguous...
Maybe we can fall back on readline? Control-G in .inputrc means "press the control and g keys at the same time", not "press the control, shift and g keys"
Same in the emacs world with things like M-X or whatever. That means the x key not a capital X
@StephenKitt Yeah. But it sounds like it does unless you pay very close attention. Before living in France, I would have sworn that it is tonic and they tend to stress the last syllable but that isn't actually true.
@StephenKitt At least in French a native should be able to pronounce any word, even new ones they've never seen before, correctly. In English, not a chance.
@StephenKitt Nah, that's fine unless you're British :P
I actually only found out that this is the normal pronunciation in the UK this year! I had always thought you had lieutenant and leftenant, since I'd seen both in print, and you'd pronounce each as written.
The crazy thing is that even though French pronunciation is largely consistent, even many French people forget the rules, and you end up with “merçi” for example...
Can't wait until the 11 when I'm flying over and I get to wallow in sweltering heat.
I am wearing long sleeves and even had a little heater on this morning in London.
Granted, in the kinds of temperatures that would make @Kusalananda complain about the heat, but 18 degrees is cold for me, dammit! And 20 in my room is unpleasant.
@terdon sorry to hear/see! That looks a bit like rain coming down from an ash cloud?!? Is Arhens a new or alternate spelling of Athens (the only city I know in Greece)

Is there a Linux distribution certified with the Single UNIX Specification? What are the primary reasons that most distributions don't get certified?
