netgviz is a set of scripts that allows you to easily make graphs illustrating layouts of computer networks at ISO/OSI layer 3. It parses a text file with a list of network nodes with their addresses and generates the data in dot format, which is suitable for a Graphviz set of tools. You can then use Graphviz to draw a graph illustrating the network topology.
FlickrFrame is a set of Perl scripts that allow you to turn a standard Linux distribution into a digital picture frame connected to Flickr.com. Users can "subscribe" to any number of Flickr photosets, which will then be display as a slide show. Photos in the frame are periodically updated by synchronizing with Flickr.com. FlickrFrame is designed to be small and run on a wide variety of hardware. It does not require the X Window System.
fastcgi-gallery is a Web gallery based on Apache::Gallery, but is hacked for usage with Perl FastCGI scripts. Therefore, this version is about 10x quicker (with cache turned on) than Apache::Gallery. With the best template system (Template-Toolkit) you can customize your gallery as you wish; for example, you can create a multi-language gallery. A database is not used; everything is stored in files. Output and generated thumbnails are cached for speed optimization.
image_album generates HTML on-the-fly for the navigation of albums of related images. It supports several different viewing modes appropriate for different display sizes and connection speeds, and allows the viewing of additional image info such as EXIF data. It uses CGI PATH_INFO-style URLs (with no '?' characters) for spiderability by all search engines.
