How to get rid of the Banner 'media contains digital photos' downloads bluetooth linux mate for ever [solved]

Problem:
When I look in my SD card, caja throws up a stupid blue banner saying "The media contains digital photos"

Cause:
Not entirely sure.  Related to gthumb-import.desktop, which has the text "Import with gThumb" which is in /usr/share/applications/gthumb-import.desktop
Nothing in mateconf-editor to tweak as well.  Bad coding...
Uninstalling  gthumb and any other image program got rid of the banner, but that is not desirable.


Solution:
Open/create the file /home/$USER/.local/share/applications/mimeapps.list and add these lines (reference http://www.freedesktop.org/wiki/Specifications/mime-actions-spec)

[Removed Associations]
x-content/image-dcf=gthumb-import.desktop;
x-content/image-picturecd=gthumb-import.desktop;brasero.desktop;

then update the mime database and killall instances of caja
sudo update-mime-database /usr/share/mime
pkill caja

Do not get happy and try modifying /usr/share/applications/mimeinfo.cache as it will get overwritten without warning.

Had a similar problem with the Downloads directory, same stupid blue banner again, "Personal File Sharing", "You can receive files over Bluetooth into this folder".
This time I uninstalled the bluetooth sharing agent:
mate-user-share
and did another pkill caja

in mateconf-editor the key /desktop/mate/file_sharing/bluetooth_obexpush_enabled looks suspicious

To all the retards that want these helpful hints, download Ubuntu please or better yet, purchase Windows / Mac OS.

caja Mint 14 mounting /media/user udisks2

New behavior in Mint 14, flash drives, usb drives now mount in /media/$USER/$DEVICE

Caused by the udisks2.  Cannot remove udisks 2 easily because the rest of the system relies on it.

A lot of people are angry about the lack of documentation associated with this major change and rightfully so.


It is still not clearly illustrated why the writer of udisks2 has decided to change the way we look at out personal filesystems but there are a few options.

Fight it:

(use google translate)
or
Create several symlinks each session, ugly...

Roll with it:
Disable caja from automounting, as it still defaults to /media/$DEVICE
run, mateconf-editor -> search for keys called automount -> disable automounting

Although there are changes to the filesystem, it still works.  Users have th be cautious upgrading their systems as torrent clients and VM on other partitions cannot be found straight away.

Getting PDW working using Virtualbox with linux host, pager decoder, pocsag

PWD is a great program for decoding pager tones, but it works only on windows.

If you are using virtualbox for windows on a Linux Host and have the group permissions set correctly, then you can decode from the sound card.

Of course you will need a scanner with a discriminator tap installed.  Connected to the input of the soundcard.

Tested on Mint Mate.

First, run alsamixer and unmute your sound card input channel, so you can monitor the sound comming in.  In my case, go to Mic and press "M" key to unmute.  The sound sound should be heard on the pc speakers.

Then open up Virtualbox (version 4) and select settings to ensure Also host driver is selected.

Then on the windows client, ensure that mic is selected, and pager tones can be recorded on the client, use sound recorder.
