There are many times I have needed a secure SSL/TLS connection to access web resources but do not want to buy a SSL/TLS certificate. Creating a self-signed SSL/TLS certificate helps streamline the process of accessing the secure resource by removing the annoying security message on your browser. When you connect to a self-signed SSL/TLS connection you will be given to option to allow the certificate for all future sessions. Now when you connect to your secure resource there will be no extra steps to gain access.

To create a self-signed SSL/TLS certificate for secure HTTPS connections with Apache there are four steps:

1. download and install the SSL/TLS scripts
2. generate a SSL/TLS key
3. create a self-signed SSL/TLS certificate
4. configure Apache to use the SSL/TLS self-signed certificate

sudo apt-get install freebsd5-buildutils

I came across another issue on my Compaq Presario C500 laptop with regards to the audio. An issue exists with the Intel 82801G (ICH7 family) High Definition Audio (HDA) audio controller with regards to the headphones.

While installing the subversion plugin Subclipse in the Eclipse IDE I came across a problem. Subclipse uses "JavaHL (JNI)" to interface with subversion by default. This default setting generates an error when accessing the "Window->Preferences->Team->SVN" preferences:
