The JACAL Project is a suite of programs, scripts, guidelines, protocols, documentation, and diskettes that assist in quick, network based loads/builds of machines. It has been used to build 70 University lab machines from scratch (No OS) in two hours. This includes NT service packs and 80+ applications on the NT side.
Jhead is a command line driven utility for extracting digital camera settings from the Exif format files used by many digital cameras. It handles the various confusing ways these can be expressed, and displays them as F-stop, shutter speed, etc. It is also able to reduce the size of digital camera JPEGs without loss of information, by deleting integral thumbnails that digital cameras put into the Exif header. If you need to add Exif support to a program, this is a simple program to cut and paste from. Many projects, including PHP, have reused code from this utility.
JReferences is a program written in Java for managing bibliographic references in the BibTeXML format. Storage is done in a binary file database or, optionally, in a MySQL database. A PHP Web frontend is available. It can input BibTex, RIS, BibTeXML, and DocBook formated references.
