Multi user multitouch operating system and monitor

Now that multitouch technology is available in common operating systems (MAC OS, Windows 7, Ubuntu 10.10 beta), it would be great to allow two users simultaneously to use the same computer (same screen, different controls, same or different applications). An example, using one computer with one big screen, I would read my emails in a browser program and simultaneously my friend would write a letter in a word processor program. We would need in total 2 keyboards and 2 mouses, or we would use simultaneously a touch screen. Such a touch screen or system would have to recognise the different users. May be by measuring the body fat percentage, by observing user gestures with a camera, or by voice recognition.

Thunderbird and IMAP remote Trash folder

[Update 2011-07-05] Before reading this post below, you may read a more recent post that shows a simpler solution applicable for all folders: here.


To specify a different Trash folder for an IMAP account in Thunderbird:

1. Completely exit Thunderbird if it is running.
2. Make a temporary backup copy of your profile folder (or at least "prefs.js").
3. Open your "prefs.js" file with a text editor such as Notepad to find the server# used to represent your IMAP account. It could be "server2", "server5", "server7", or some other number depending on your own individual account setup. Look for a line similar to this, corresponding to your own IMAP acccount:

user_pref("mail.server.server2.hostname", "mail.YourImapProvider.com");

4. Insert a line like the following into "prefs.js", with the correct server# and correct name for the Trash folder:

user_pref("mail.server.server#.trash_folder_name", "");

For example:

user_pref("mail.server.server2.trash_folder_name", "Deleted Items");

If you want to use "Gelöscht" (German for Trash) you would have to write it in the user_pref as "Gel&APY-scht", since the German Umlaute has to be encoded differently.

5. Restart Thunderbird. You should now see the new Trash folder (e.g., "Deleted Items") showing the trash can icon. (If not, exit and restart Thunderbird.) If the old Trash folder is still showing, you should now be able to delete it. If you can't delete it through Thunderbird, then delete it through the account's webmail interface.

6. If you deleted the Trash folder in the web front end of your mail provider, you may need to cancel the IMAP folder subscriptions, too. It may take a while for the subscription changes to take effect.
