Linux

It makes me mad to see the current state sway is in, I even bought an AMD GPU for nothing.

In the earlier days of Plasma 6, it would crash on me when waking from sleep, so I had a small script that would basically restart plasmashell when waking so I didn't have to wait the several seconds for the system to realize that it was frozen before I had a functional desktop.

gtk3-classic still doesn't work properly on Wayland and I doubt it will ever be fixed so I include WAYLAND_DISPLAY=0 in each shortcut file to force them into xwayland.

I wrote a script to turn the power of the the Wifi+Bluetooth chip off, then enumerate the PCIe bus again to start it back up.

The chip sometimes hung itself when using both. I looked for the bug and even found an Intel engineer on some mailing list admitting that they had issues with coexistance mode.

Just turning the wireless off and back on wasn't enough I needed to reeinitialize the hardware and that was the best way I knew.

On the client side of a relayd-based wireless bridge using OpenWrt, I discovered there was a bug in that relayd version which made the process hang after it moved so many gigs of data. I made a cron job that pings the network relayd makes accessible. If the ping fails, it nukes relayd. Of course this relies on a live machine to ping. If this machine dies for some reason, the cron job would just keep killing relayd over and over again. 🥹

Here's a few of the micro-hacks that I've hacked up in the past.

#!/bin/sh  

clear  
doas chroot /linux /bin/login

#!/bin/sh
#Works only for C
vim $1.c && cc -O3 -Wall -Werror -Wno-unused-result $1.c -o $1
#MODE=`stat -f "%OLp" $1`
if ("stat -f "%OLp" $1 | grep -e 6 -e 4 -e 2") then
	chmod +x $1
fi

#!/bin/sh

#dos2unix -O -e -s $1 | sed 's/    /	/g' | sed 's/“/"/g' | sed 's/”/"/g'
cat $1 | sed 's/    /	/g' | sed 's/“/"/g' | sed 's/”/"/g'
#Convert DOS line endings to Unix ones and add a final newline if there isn't one,
#replace sequence of 4 spaces with tab,
#and replace "smart" quotes with normal ones

I just keep those ones for historical value, but there's one hack I use every day. My keyboard doesn't have a function key (Fn), so I use the Super/Windows key instead.
I have xdotool keyup Super_L keyup Super_R keyup F4 key XF86Sleep bound to a custom keyboard shortcut. It unpresses the keys used for the shortcut (Super + F4), then presses the sleep key.

Don't remember the specifics but I had a key combo setup to force a soft reset in my DE. Occasionally a kernel or driver update would fuck up my video and make the system unusable but still live. I try to avoid hard resets.

Bootstraping.

wayland.windowManager.sway.config.keybindings = let
    # ...
    screenshot = with pkgs; writeShellScriptBin "screenshot.sh" ''
          DATE=$(date +"%Y%m%d%H%M%S")
          if [ "$1" = "full" ]; then
            ${grim}/bin/grim ~/Pictures/shot_$DATE.png
            ${libnotify}/bin/notify-send "saved full screenshot to shot_$DATE.png"
          elif [ "$1" = "full-copy" ]; then
            ${grim}/bin/grim - | ${wl-clipboard}/bin/wl-copy -t image/png
            ${libnotify}/bin/notify-send "copied full screenshot"
          elif [ "$1" = "sel" ]; then
            ${grim}/bin/grim -g "$(${slurp}/bin/slurp)" ~/Pictures/sel_$(date +"%Y%m%d%H%M%S").png
            ${libnotify}/bin/notify-send "saved selection to sel_$DATE.png"
          elif [ "$1" = "sel-copy" ]; then
            ${grim}/bin/grim -g "$(${slurp}/bin/slurp)" - | ${wl-clipboard}/bin/wl-copy -t image/png
            ${libnotify}/bin/notify-send "copied screenshot"
          else
            printf "Invalid argument: '$1'\n"
          fi
          '';
  in lib.mkOptionDefault { # ...

This is in my Home Manager configuration. I don't think this is that bad, it's just kinda messy. If you can't tell, it's a script for taking screenshots, embedded in my configuration.

I made a script to add a middle click scroll function with a toggle. I can share the script, it's a really bash script

My Fedora distro can't restart and stalls when it tries to shutdown with the auto update checked. So it never shuts down. I set up a cronjon to run dnf update to make sure that I don't need to uncheck the auto update option. Just a really silly thing that bothers me.

I’ll leave this one here for someone:

You can tunnel L2 over OpenVPN. Just bridge your interfaces in both sides and it works.

That way if you need to provision a VOIP phone or just have something NetBoot remotely. Not that I recommend doing that…

About a decade ago I was playing a game on Linux and the game crashed and took the entire DE with it. So I went to a different tty and started a fresh x desktop session and started playing again until the game crashed again (I was running a bunch of mods so it would crash every couple of hours or so) and still didn't feel like rebooting so I went to yet another tty and started yet another x desktop session. I did this about 3 times in total before I finally went "I should probably actually reboot because this has to be making a bigger mess of things"
