Updating Azureus

When I have problems with Azureus I update it with the latest version and it usually gets fixed. The only thing you have to do is replace the Azureus.jar file like this:
Download the newest Azureus.jar (currently, it's here)

Once you have saved it in a folder called, say, "Downloads", you do this in a Terminal:

Backup your old Azureus.jar:
sudo cp /usr/share/java/Azureus2.jar /usr/share/java/Azureus2.jar.bak

Then remove the old version:
sudo rm /usr/share/java/Azureus2.jar

Then copy the newest version to where it should be:
sudo cp Downloads/Azureus2.5.0.4.jar /usr/share/java/Azureus2.jar

Installing and setting up Sun Java

To install Sun Java, you need to install the sun-java6-bin and sun-java6-jre packages. Additionally, if you intend to program your own Java applications, you need to install sun-java6-jdk. Multiverse has to be enabled.

sudo aptitude install sun-java6-bin sun-java6-jre sun-java6-jdk

Next, to make Sun Java the default Java interpreter (rather than GCJ):
sudo update-alternatives --config java

and choose the correct option for Sun Java, ie. /usr/lib/jvm/java-6-sun/jre/bin/java.

Installing checkgmail

CheckGmail is a Gnome Panel Applet that checks your gmail account.
To install it, first install all the dependencies:

sudo aptitude install libcompress-zlib-perl libcrypt-blowfish-perl libcrypt-simple-perl libcrypt-ssleay-perl libemail-mime-encodings-perl libfreezethaw-perl libgtk2-trayicon-perl libmd5-perl libxml-libxml-common-perl libxml-libxml-perl libxml-namespacesupport-perl libxml-simple-perl

Then, download the tarball package version of CheckGmail from here. Extract (say to /home/username/Programs/checkgmail) and then add it to your start up programs (System -> Preferences -> Sessions). To run CheckGmail for the first time, run the checkgmail script from the startup directory.

To get cool On-Screen Display notifications of new emails, install gnome-osd:
sudo aptitude install gnome-osd

Then, right click on the CheckGmail icon, click Preferences and in the "Command to excecute on new mail" field enter the following:
gnome-osd-client -f "<message id='gmail'><span foreground='black' background='lightgray'>%m new email(s)</span></message>"

To get your CapsLock/NumLock/ScrollLock light(s) blinking when you get new email install blinkd:
sudo aptitude install blinkd

and then add this to the field above:
;blink -s -r %m

The field should now look like this:
gnome-osd-client -f "<message id='gmail'><span foreground='black' background='lightgray'>%m new email(s)</span></message>";blink -s -r %m

and add this to the "Command to excecute for no mail" field:
blink -s -r 0

This will make the ScrollLock light blink n times, where n is the number of new email messages, and will make it stop blinking when you have read all your mail.
