The "Linux questions (and other stuff)" thread

Me? I LOVE the command line! I still do all my real work there.

Ah, a woman after my own heart! :) To me any computer I can't launch a bash shell on (or zsh at a pinch) is essentially useless for work.

To show I'm not kidding, I just had a quick look at my laptop and can see 16 terminal windows open (spread over 13 virtual desktops - I use different workspaces for different projects and tasks). But several of those have more than one tab, so that's an underestimate of the number of command lines I have going. I can do virtually anything faster with a command line than a graphical file browser, so rarely open those things.

(OK, this is a Macbook, but that's just a BSD derivative with a different GUI on it, so it's still a *nix. And I use Linux for all of my serious computing, entirely via the command line).
 
There's a teacher looking for guidance setting up a private server, having their students connecting to it with Kindle Fires.

I've gone as far as I can go in the thread.

I know the project can be done--at both ends, i.e., probably rooting the Kindles and providing a locked-down, fixed GUI for the students, and setting up the required services on the Linux box--but I cannot provide the know-how.

I'd appreciate any of you dual Linux/Android geeks popping in to see what you can do. Thanks!
 
I can't remember what machine it was, but I'm thinking it was probably an ancient Pentium or PII...

I do use the CLI for work, and in fact I teach my minions everything they need to know about the CLI (pertaining to our current job, which is like fifteen commands at most).
 
My printer stopped working and I don't know why. :(

In the screenshot, you'll see that I'm getting this: /usr/lib/cups/backend/hp failed

Also in the screenshot, note that the executable file hp exists in /usr/lib/cups/backend.

This is the PC running Kubuntu 9.10 whose pic of it booting up I recently posted.

The printer is an HP Deskjet F4100 Series; its age is ≈12 years old. Nothing has been changed in its settings or its system files in YEARS.

I've tried all the obvious things, but have gotten nowhere.

Ideas?
 
Mint 19 does not come with a KDE version.

Some day I will have to decide whether I like KDE or Mint better, and I am leaning toward Mint.

I mean, xfce does a lot of the things KDE-like, though it's not nearly as flexible... though I see one person on the Mint forums managed to force-update their 18.3 KDE to 19. Mayhaps I will give that a try (with a fresh install of 18.3).
 
Also, look at the log straight after the problem occurs. Chances are there would be diagnostic messages right at the end of the log

use command

> less /var/log/cups/error_log

and hit G to go to the end of the file. Sorry if I'm teaching granny to suck eggs there :)

Will do.

You are, but I don't mind. In fact, I appreciate it. Not only is it helpful for oh-so-rusty me, but it can teach newcomers a thing or two, too.
 
Eyes glazed over, these 20-yr-old children could not think of any reason why one would need to use a regular expression more complicated than *.*

Though it was pretty amusing when I used as an example, under the aegis of make sure you know what you do in a search/replace, of replacing "ass" with "butt" and ending up turning "association" into "buttociation".
 
Because I like Mint, heh.

TBH I haven't gone to KDE.org since the last century, when Kommando was king and their aesthetic was ugly as all hell.

I suppose I should wander over there and see what things like like now.
