+Stubborn machine insists on sleeping? These mods should do the trick:
+  sudo nano /etc/systemd/sleep.conf
+  AllowSuspend=no
+  AllowHibernation=no
+  AllowSuspendThenHibernate=no
+  AllowHybridSleep=no
+  sudo systemctl mask sleep.target suspend.target hibernate.target hybrid-sleep.target
+Mask hd-idle to stop it from interferring with external HD sleep / spin down:
+  sudo systemctl mask hd-idle.service
+Clear systemd logs:
+  # Clear entire journal (all logs from all time)
+  journalctl --vacuum-time=1s
+  # Or keep only last 1 hour (safer if you want some recent context)
+  journalctl --vacuum-time=1h
+  # Vacuum by size (keep only 100MB)
+  journalctl --vacuum-size=100M
+  # Rotate and vacuum everything
+  journalctl --rotate --vacuum-time=1s
+Where are flatpak binaries/executables? Here's Pulsar's:
+  /var/lib/flatpak/app/dev.pulsar_edit.Pulsar/current/active/export/bin/dev.pulsar_edit.Pulsar
+See what kind of hard drives you have and which one is boot and which not, etc.:
+  sudo lsblk -d -o NAME,SIZE,TYPE,MODEL,TRAN,ROTA,VENDOR,SERIAL
+  sudo lsblk -o NAME,SIZE,TRAN,ROTA,MOUNTPOINT $(findmnt -n -o SOURCE / | sed 's/[0-9]*$//')
+  df -h
+Google Chrome does the "won't open shit" despite re-install, restart, etc.:
+  rm -f ~/.config/google-chrome/SingletonLock
+  rm -f ~/.config/google-chrome/SingletonCookie
+  rm -f ~/.config/google-chrome/SingletonSocket
+Stop Chrome/Chromium from messing with input level of mic:
+  chrome://flags
+  Allow WebRTC to adjust input volume
+  <disabled>
