I am just experimenting these days with Ubuntu 8.10, installed quite a bit of apps, tried different themes, but today got Twhirl working on my machine. Thought you people might be interested.

1. First you need to download Adobe AIR from http://labs.adobe.com/downloads/air_linux.html

2. Install Adobe AIR

root:~/adobe$ chmod +x adobeair_linux_b1_091508.bin

rppt:~/adobe$ ./adobeair_linux_b1_091508.bin

3. After installing Adobe Air download Twhirl from http://www.twhirl.org/project/twhirl

4. Open the Twhirl application with Adobe Air and here you go, Twhirl is installed.

Linux Keyboard Shortcuts

In Linux, when your entire system freezes, there are plenty of safe ways to exit and get back on track immediately. Alt + SysRq + (a selection of other keys) will do the magic trick. Note: ‘SysRq’ key is equivalent to the ‘Print Screen‘ key.

Alt + SysR + K
Kill all processes (including X), which are running on the currently active virtual console.

Alt + SysRq + E
Send the TERM signal to all running processes except init, asking them to exit.

Alt + SysRq + I
Send the KILL signal to all running processes except init.

Alt + SysRq + L
Send the KILL signal to all processes, including init.

Alt + SysRq + S
Run an emergency sync (cache write) on all mounted filesystems. This can prevent data loss.

Alt + SysRq + U
Remount all mounted filesystems as read-only. This has the same effect as the sync combination above, but with one important benefit: if the operation is successful, fsck won’t have to check all filesystems after a computer hardware reset.

Alt + SysRq + R
Turn off keyboard raw mode. This can be useful when your X session hangs. After issueing this command you may be able to use .

Alt + SysRq + B
Reboot immediately without syncing or unmounting your disks. Using this, you will likely end up with filesystem errors, so this is not highly recommended.

Alt + SysRq + O
Shut the system off right away.

If all these ‘Alt + SysRq’ keyboard combo are hard to remember, you can press Alt + SysRq + H to display a helpful list of the shortcuts above.
