To discover which plugin is used for specific file run command similar to this:
gst-launch -v filesrc location=filename_here ! decodebin ! autoaudiosink
that should give you (among other things) output lines similar to these:
...
/GstPipeline:pipeline0/GstDecodeBin:decodebin0/GstTypeFindElement:typefind.GstPad:src: caps = application/x-id3
/GstPipeline:pipeline0/GstDecodeBin:decodebin0/GstID3Demux:id3demux0.GstPad:sink: caps = application/x-id3
Pipeline is PREROLLING ...


Nice article listing some of them:

Check /var/log/zimbra.log, username connected is logged as sasl_username

Make cell's content formula (ie "=blah blah blah"); when you get value you need copy it to clipboard, then choose paste special instead of normal paste and uncheck pasting formulas.

For setting up X server follow instructions here. (Long story short, use nvidia driver, add glx and extmod extensions to xorg.conf, and add argb-glx-visuals to monitor.)

Like this:
mdconfig /path/to/iso
mount -t cd9660 /dev/mdX /mountpoint

X being md unit reported by mdconfig command.

After done with ISO unmount it and delete md created for it:
umount /mountpoint
mdconfig -d -u X

(Again X being md unit as reported during creation)

Using python from command line:
cat file.json | python -mjson.tool


Keep in mind this will sort keys in structures.

If you created and compiled unit tests using MonoDevelop you need to copy several dlls to the same directory before you can use nunit-console with compiled dll. Those libraries can be found /usr/local/lib/monodevelop/AddIns/NUnit directory
