Mouse Shortcuts/Tricks for Ubuntu Unity

Clicking and holding an icon and then dragging it around will allow you to reorder it on the launcher. You can also drag it off to the right of the launcher to move it around. Note that you need to make an explicit movement to the right to move the icon off the launcher before you can move it around.
Dragging and Dropping an icon into the trash can will remove it from the Launcher.
Moving and holding the cursor on the left side for a few seconds will launch Unity dock.
Moving the cursor to top-left corner(near Ubuntu icon) will launch Unity dock as well.
Scrolling the mouse wheel while over the Launcher scrolls the icons if you have too many and need to move around quickly.
By Scrolling the mouse wheel while over the Sound icon on top panel helps you increase or decrease system volume.
Middle click on an application’s launcher icon – Open a new instance of the application in a new window. Very useful at times. In laptops with touchpads, hitting left/right click buttons together is akin to middle click.
Maximizing – Dragging a window to the top panel will maximize it.
Restore/Unmaximize – Dragging the top panel down OR double clicking on the top panel will do.

How to Convert Videos with Transmageddon in Ubuntu Linux

Whether you want to listen to music on your smartphone or watch movies on your iPad, you may need to convert you media files from one format to another depending on what your devices support.

Transmageddon Video Transcoder is a great media converter for Ubuntu. It converts audio and video files, it has a simple interface, and it’s free. Installation is easy. Just type this command in the terminal:

sudo apt-get install transmageddon

Or use the Software Center:

Transmageddon is now installed, so let’s start converting videos. Launch it from the applications menu. The application looks like this:

At the top you choose the input file which you want to convert. Click the button and navigate to the file you want it converted then click “Open”.

You can see the input video properties just below the “Choose Input File” button. If you have a specific device you want to play the video on, then select your device from the “Preset” drop-down menu so the program adjusts the conversion settings appropriately otherwise leave it blank. Now select the target format you want from the “Output Format” menu. Right below that are the settings for audio and video codec. Choose the settings you desire. You can choose different audio/video codecs with different qualities and formats.  At the bottom of the window you can choose whether to rotate the video image or not. This might come in handy if you were shooting a video then found out later that you were holding that you were holding the camera upside down (or if you like to watch videos upside down which would be weird).

After you finish choosing the settings you want, hit “Transcode” to start the conversion process. It may take a while depending on the length of the video and the setting you choose. You will find the output file in under Videos in your Home directory. Easy, isn’t it?

Sebelumnya saya menggunakan ubuntuzilla untuk menggunakan upgrade Firefox di Ubuntu 9.04 Jaunty, tetapi hal tsb gak ampuh untuk dikantor yng ftp portnya di blok oleh tembok api.  Sedikit informasi ubuntuzilla untuk proses donwloadnya menggunakan port ftp.

Untuk menyiasati hal tersebut, saya jalankan upgrade secara manual, dengan langkah sebagai berikut :

1. Download firefox*.tar.bz2 dan simpan difolder yang dikehendaki, dengan perintah wget "http://download.mozilla.org/?product=firefox-3.5.2&os=linux&lang=en-US"

2. Ekstrak file, tar xvjf firefox-*.bz2

3. Copy kan file ke folder /usr/lib, sudo cp -r firefox /usr/lib/firefox-3.5.2

4. Backup file firefox di /usr/bin ke firefox.old sudo mv /usr/bin/firefox /usr/bin/firefox.old

5. Bikin symbolic link, sudo ln -s /usr/lib/firefox-3.5.2/firefox /usr/bin/firefox-3.5.2

6. Dan link terakhir , sudo ln -s /usr/bin/firefox-3.5.2 /usr/bin/firefox

7. Restart Firefox

Semua berjalan dengan baik, jika ada masalah dapat melakukan restore versi sebelumnya, lakukan perintah sbb :

  1. sudo mv /usr/bin/firefox /usr/bin/firefox.bak
  2. sudo mv /usr/bin/firefox.old /usr/bin/firefox

Thx.
