  • Changing key mapping with xmodmap is broken. Is there a workaround?

    Jump

  • Yes. I’m just keeping the symbols file in home directory so that I don’t have to edit the system files. To change backspace you’d have something like the following I believe:

     
                key <BKSP> {    [ BackSpace, Delete ] };

  • Hot take: Lemmy is an even bigger piece of garbage than Reddit.

  • How much of a pain is it to install Nvidia GPU drivers, really?

    Jump

  • It’s trivial. Use Linux Mint or Debian, enable non-free repositories if required, and that’s pretty much it.

    I’ve never had issues with Nvidia drivers. Your mileage may vary.

  • It is a product of its time. If the same research was made 30 years ago, I bet there would be a stark difference to results today. LTO wasn’t as feasible. Compilers were less capable of removing redundant checks. Branch prediction in x86 processors was still a hot new thing. And on top of it all, there was less knowledge about language development.

    What are your opinions on this?

  • Who cares what anyone on r/macos thinks.

  • Icon and .desktop file if you want one for Doom Emacs

    Jump

  • Also, nano may not always be installed.

    mcedit, gedit, pico. For majority of people lack of any simple non-vi-based text editor is a corner case not worth worrying about. Definitely not enough of a problem to start ‘How to learn Emacs’ tutorial with ‘Learn Vim’.

  • Why is 0th step of learning Emacs, learning Vim? The whole premiss that you need to know Vim or you’re unable to work on other people’s computers is ludicrous. Nano is perfectly capable editor for the times I need to use computers without Emacs.

  • Admittedly, I’m probably not the best person to ask for recommendation of a noob-friendly distro, but I feel people are overthinking this. If someone produces a list which includes distros I’ve never heard of, I think they spent too much time on ‘Top 10 Noob Friendly Distros in 2025’ websites.

    If you really care about my recommendation, just start with Mint.

    PS. I should also add, this isn’t criticism of you or any other new user who does search online for recommendation. This is more a comment on state of the Internet where there are so many websites which seem to pad their list with obscure distros where really all such articles should give recommendation for one of the same three distributions. Which three I don’t exactly know.

  • src/* will skip hidden files. You want rsync -avAXUNH src/ dst which copies contents of src into dst. Notice the trailing slash in src/. Without the slash, src is copied into dst so you end up with a src directory in dst. The AXUNH enables preserving more things. You might also add --delete if you’re updating the copy.

    PS. I should also mention how I end up with -avAXUNH. Simple:

     
        
$ man rsync |grep ' -. *preserve'
       --hard-links, -H         preserve hard links
       --perms, -p              preserve permissions
       --executability, -E      preserve executability
       --acls, -A               preserve ACLs (implies --perms)
       --xattrs, -X             preserve extended attributes
       --owner, -o              preserve owner (super-user only)
       --group, -g              preserve group
       --times, -t              preserve modification times
       --atimes, -U             preserve access (use) times
       --crtimes, -N            preserve create times (newness)

    and then include all that. a covers some of those options and those don’t have to be set explicitly:

     
        
$ man rsync |grep ' -a ' |head -n1
       --archive, -a            archive mode is -rlptgoD (no -A,-X,-U,-N,-H)

  • good XMPP client for emacs

    Jump

  • Have you looked at Bitlbee? Not a client for Emacs as such, but an IRC gateway to various protocols. It lets you use your IRC client to talk to XMPP.

  • What others wrote except don’t use dd. Use rsync or make a backup with tar. dd will waste time reading unallocated regions of the disk.

  • Is Ctrl+D really like Enter?

  • I meant what’s the link to use since the same Lemmy post can be viewed through different instances and on each it has a different URL. It’s a bit user-hostile that the link gets you out of your instance (unless you’re on the same instance as author of the post).

  • Is Ctrl+D really like Enter?

    Jump

  • Yeah, it’s a bit philosophical.

    • In graphical applications, Ctrl+M, Ctrl+J and Return/Enter are all different things.
    • In a terminal in raw mode, Ctrl+M and Return/Enter are the same thing but Ctrl+J is something different. You can for example run bind -x '"\C-j":"echo a"' in bash and Ctrl+J will do something different.
    • In a terminal in canonical mode, they are all the same thing. There probably are some stty options which can change that though.

  • Is Ctrl+D really like Enter?

    Jump

  • Yes. So is Ctrl+J actually. Ctrl+J corresponds to line feed (LF) and Ctrl+M corresponds to carriage return (CR) ASCII characters. They are typically treated the same way.

  • Is Ctrl+D really like Enter?

    Jump

  • Yes, I agree. But the dispute is what ‘sends EOF’ actually means. The article I respond to claims Ctrl+D doesn’t send EOF but is like Enter except that new line character is not sent. This is, in some sense true, but as I explain also misleading.

  • look for symlinks pointing at the contents of directory?

    Jump

  • You could pass $1 and $got through $(realpath -P -- ...) to make sure all the path are in canonical form. Though now that I’m thinking about it, stat is probably a better option anyway:

     shell
        
want=/path/to/target/dir
pattern=$(stat -c^%d:%i: -- "$want")
find "$HOME" -type l -exec stat -Lc%d:%i:%n {} + | grep "$pattern"
