Apache virtual hosts quick and easy

Wednesday, 03 October 2007
Virtual hosts are used to run more than one web site on a single machine. Virtual hosts can be "IP-based", meaning that you have a different IP address for every web site, or "name-based", meaning that you have multiple names running on each IP address. You can also run your web pages on different ports like 8080 or 8090. The fact that they are running on the same physical server is not apparent to the end user. This workshop describes the different setups based on an OpenSuse 10.2 server.

Xara Xtreme for Linux, a powerful graphics program

Wednesday, 12 September 2007
Xara Xtreme for Linux is a powerful, general purpose graphics program for Unix platforms including Linux, FreeBSD and (in development) OS-X. Xara Xtreme is based on Xara Xtreme for Windows . The source code was made available open-source in early 2006, and is being ported to Linux. The downloadable version of Xara Xtreme for Linux is working straight away on most Linux machines, but the development is continuing daily. At the moment two versions are available for download. The first is the recommended download because it will normally be the most stable. The second is the very latest, but untested version, built and published automatically. Warning: It may be unstable. Linux-Tip was using the latest stable version provided as an “Autopackage Archive” on a Open Suse 10.2 Desktop. We recommend connecting your system to the Internet. In this case the script can easily download and install the necessary packages automatically.
