The price is larger than for the Raspberry Pi: $74 (including shipping), but the new mini PC has better hardware. And it's a lot cheaper than Cotton Candy, which does have a dual-core CPU and 1GB of RAM, but it costs $199 plus shipping and further more, the pre-orders have been closed for now.
MK802 can be purchased via aliexpress.com (US $74.0)

Nautilus Columns is a Nautilus extension that displays PDF and audio (mp3, WAV and FLAC) tags as well as EXIF metadata to the Nautilus List View. The extension has been updated recently by WebUpd8 reader Arun to work with Nautilus 3.4 so you can use it in the latest Ubuntu 12.04 LTS.
The extension supports displaying the following info in the Nautilus list view columns:

• mp3, WAV, FLAC: artist, track, album, title, bitrate, date, genre, length and sample rate
• EXIF: dateshot, image size, software and flash
• PDF: title, author (displayed under "Artist")

Screenshots:





To install Nautilus Columns in Ubuntu 12.04 Precise Pangolin, use the commands below:

sudo add-apt-repository ppa:nilarimogard/webupd8
sudo apt-get update
sudo apt-get install nautilus-columns

Then, restart Nautilus (the .deb tries to do this automatically, but just in case):

nautilus -q

Once installed, in Nautilus select Edit > Preferences and on the "List Columns" tab, enable the audio, EXIF and PDF metadata that you want to be displayed. This info is only displayed in the list view so select View > List from the Nautilus menu (or use CTRL + 2).
That's it for Ubuntu 12.04 users.
For other Linux distributions, you can download Nautilus Columns from HERE. Important: this version doesn't work with Nautilus versions older than 3.4! To install it, extract the archive and copy the "bsc-v2.py" file to one of the following folders (if they don't exist, create it):

• for the current user: ~/.local/share/nautilus-python/extensions/
• for all users: /usr/share/nautilus-python/extensions/

You'll also need to install some dependencies: python-nautilus, python-mutagen, python-pyexiv2, python-kaa-metadata, libnautilus-extension1a and python-pypdf (they might have a different name, depending on your the Linux distribution). After you've installed everything, remember to restart Nautilus.
Thanks to Arun for porting Nautilus Columns to Nautilus 3.4!

The GNOME Shell Window Buttons extension has been updated for GNOME Shell 3.4 and is now available in the WebUpd8 GNOME 3 PPA.
Window Buttons is an extension that displays the minimize, maximize and close window buttons on the top GNOME Shell bar, like in Unity. The buttons order or theme can be customize and the extension comes with 5 built-in themes: Ambiance, Radiance, Zukitwo, Zukitwo Dark and a generic (default) theme.

Install and configure GNOME Shell Window Buttons extension

To add the WebUpd8 GNOME 3 PPA and install GNOME Shell Window Buttons extension in Ubuntu 12.04 (there's also an older version available for Ubuntu 11.10 with GNOME Shell 3.2), use the commands below:

sudo add-apt-repository ppa:webupd8team/gnome3
sudo apt-get update
sudo apt-get install gnome-shell-extension-window-buttons

Once installed, restart GNOME Shell and activate "Window Buttons" using GNOME Tweak Tool.

The extension has been tested with Ubuntu 12.04 and GNOME Shell 3.4.1 but it should work on other Linux distributions too (not tested!) - you can download it from HERE.

Window Buttons on the top GNOME Shell bar, window titlebar removed using Maximus

The extension can be configured using Dconf Editor - if it's not already installed, use the command below to install it:

sudo apt-get install dconf-tools

Then run Dconf Editor and navigate to org > gnome > shell > extensions > window-buttons. Here, you can change various settings, such as:

• theme: set the theme you want to use: "Ambiance", "Radiance", "Zukitwo", "Zukitwo-Dark" or "default"
• pinch: set the window buttons like Mutter, Metacity or Custom.
• order: if you've set the pinch (see above) to Custom, here you can set the button order
• onlymax, hideonnomax: enabling these two options, the window buttons will be hidden when there are no maximized windows. This option is a bit buggy, to get it to work, use the maximize/unmaximize button on the top GNOME Shell bar a few times and the buttons should dissapear when there are no maximized windows.

After changing some of the settings, like the theme, you must restart GNOME Shell.

 To automatically remove maximized windows titlebar, you can use Maximus  - for more info, see: How To Remove Maximized Windows Titlebar In GNOME Shell


You can get the window buttons on the panel using the Classic (Fallback) GNOME Session too, see:  `Window Applets`, Finally Available For GNOME 3 (Classic / Fallback)


Thanks to tiper, Sander Deryckere and barravi for updating the extension to work with GNOME Shell 3.4!
