I was looking for a tea timer countdown but quickly realised I might as well use a countdown script for this. I based my script on the linked script but added a customizable notification at the end

$ nano ~/bin/countdown

#!/bin/bash
# v2 - 2019-05-01
secs=$1
msg=${2:-$1 seconds passed.}
while [ $secs -gt 0 ]; do
   echo -ne "$secs\033[0K\r"
   sleep 1
   : $((secs--))
done
notify-send 'Countdown Finished' "$msg"

$ chmod +x ~/bin/countdown
$ countdown 180 "Tea is ready."

#linux

So I was seeing graphical glitches, freezes and Activity Monitor indicated memory pressure. Turns out macOS doesn't mount a swap file, as I am running from an external SSD install.

This is easily fixed. I can't believe it is a problem though.

By the way I had to change the end of line 4 (because the command in the Ask Different answer returned multiple results) to:

VM_VOLUME=$(/usr/sbin/diskutil list | grep "VM" | awk 'NR==1{print $7;exit }')

It's easy to add the launch item using Lingon X and start it with sudo ./mountvm.sh for the current session.

As a security conscious person I setup my OpenPGP keys with a passphrase, however on OpenSUSE Leap 15 this causes a login prompt to appear that delays the network connection from initiating. The same issue also blocks software updates and means a browser restart due to DNS cache stopping connections to websites. This is fairly annoying.

It turns out that this can be fixed by sharing the network connection via Connections > open the connection > General Configuration > All users may connect to this network. This causes NetworkManager to cache the required  authorization tokens (this is my understanding).

Note that other software such as Kontact might set a daemon to startup by default, causing the same prompt. This can be unticked in its settings.

If everything else fails, then you could remove the passphrase for the PGP key but this is not recommended as this means someone can take on your identity should your key be exposed for any reason.
