comment FFmpeg: image intro
With the -itsoffset 5 it will put the intro in front and shift the video by 5 seconds, or remove that to overlay with no shifting. To add an outro you can add a 3rd input like the 2nd (-r + -loop + -i), and add more filters to alpha-fade it in at the desired frame (e.g. length of the video × frame rate) and overlay it. You can have as many filters as you like (e.g. fade in, watermark), separated by ;, within a single -filter_complex argument. See the documentation for complete details and some examples.

comment Automatic updates of Firefox (stable and beta) don't work on OS X
The aurora/nightly builds are automatically generated and I don't think it uses all of the variables to pick one, whereas beta and stable are tested and have officially supported versions and platforms.

@Ube: Darwin_x86_64-gcc3-u-i386-x86_64 means a universal binary supporting both i386 and x86_64, running on x86_64. Darwin_x86_64-gcc‌​3 means that you are running an x86_64-only version. The distribution Mac builds are universal; there are no x86_64-only updates. Did you build it yourself or strip out the i386 part? file /Applications/Firefox.app/Contents/MacOS/firefox in a Terminal will show which architectures your firefox binary supports. I don't know how it got that way but you could potentially edit app.update.url and replace %BUILD_TARGET% with Darwin_x86_64-gcc3-u-i386-x86_64.

comment Hard symbolic link directory
They are probably under different mount points, so they are not hard links, although they may end up referencing the same directory.

comment Linux - Increase volume for HD mp4 files
If you can just copy the audio data (-acodec copy) then there should be no difference between input and output audio, unless you have audio level metadata that you are not copying (EBU R128 or ReplayGain).
