These are only examples, for a few very common actions. You are expected to write your own rules for the rest. The syntax is regular JavaScript, but see the polkit(8) manpage for the object structure and available API. These examples are for polkit versions 106 and later, with the JS interpreter. They won't work with Debian's polkit v105.

• If you don't know the action name, run pkaction:

  pkaction | grep cups
  

• The possible results are YES, AUTH_SELF(_KEEP), AUTH_ADMIN(_KEEP), NO. Returning a result is final. Returning null will continue checking other rules.

• Put your rules in /etc/polkit-1/rules.d/*.rules. (You can check everything in one giant addRule, or you can have a separate file and separate addRule for each program; it doesn't matter.)

Read-only FS on Arch Linux ARM

Unlike your typical computer where you usually shutdown properly, I cannot rely on this during the use of my Raspberry Pi. If the Raspberry Pi is improperly shutdown too many times, data corruption in the file system leading to unbootable SD card may result. So we should use a read-only file system.

Full instructions and explanations are obtained from this link but you can run these commands directly. I modified some of the instructions for personal convenience.

Login with default username: alarm, password: alarm

#Optionally enable root over SSH. The rest of these instructions assume u are in root.

Live Transcoding

This is a collection of working commandline examples to show how one could use FFMpeg and VLC for live transcoding of video streams. All examples have been tested on OSX 10.7.5 with FFMPeg 1.1.3 and VLC 2.0.5 in early 2013.

Documentation links

• FFMpeg, Muxers, Encoders, Protocols
• FFMPEG multiple outputs
• VLC Docu, Advanced Use
