This is nice! On OSX, processes can be paused and continued too (by name via killall, and by PID via kill): kill -STOP 1234 kill -CONT 1234 killall -STOP -c "Pandora" killall -CONT -c "Pandora" A more nuanced control is to throttle down the CPU, via cputhrottle[1]. If I'm running a CPU-intensive calculation and don't want to bog down the rest of my system I will use it to give me enough cycles for Sublime Text to wor…

  #!/bin/bash
  
  currentProcess=$(xprop -id $(xprop -root | grep -F '_NET_ACTIVE_WINDOW(WINDOW)' | awk '{print $5}') | grep -F '_NET_WM_PID(CARDINAL)' | awk '{print $3}')
  
  state=$(grep 'State:' /proc/$currentProcess/status | awk '{print $2}')
  
  if [[ "$state" == "T" ]]
  then
      kill -CONT $currentProcess
  else
      kill -STOP $currentProcess
  fi

Wow, coded like a simple old school Win32 API win app, I didn't realize that was still possible in modern Visual Bloatio. Nicely done.

Earlier quoted context omitted.

As someone who just switched to Linux from OS X, it is really hard to migrate. I miss the subtleties of the apple ecosystem. Sure Linux is awesome, but I have been battling trackpad support issues, keymapping the super_key to CMD, and just general battling the UX. tl;dr a more powerful operating system with worse UI, which is the obvious trade. A less powerful system with a fantastic UI.

UI is subjective. I get mildly annoyed whenever I use a Mac. Little things like having to click on a window to give it focus, or having to use command instead of control in many programs, break my flow. I'd probably get used to those if I only used a Mac, but since I use Linux 95% of the time and Mac 5%, I never do.

This specific example is nice although not truly universal. An interesting startup idea would be a bluetooth thingy (kinda vague, maybe a necklace?) that when pushed becomes a TRUE universal pause button. Pauses my DVR, my car audio, my linux mythtv box, everything, silences my phone ringer, mutes the TV, shuts off the alarm clock, temp-mutes the smoke alarm if its currently going off, silence the oven timer, car ala…
