Debian From Scratch is really two related components in one. First, it's a live bootable CD image that is designed to provide a full-featured kernel and rescue environment. It includes filesystem tools, editors, C compilers, Python, Perl, and everything you need to manually install Debian on a new machine. On ix86 machines, Grub is used to boot directly from the CD. There is also a program that is used to create the DFS CD images. It is highly configurable and can be used to create other custom bootable CD or DVD images. You can include whatever kernel or packages you want.
Dpsyco is a automated system to distribute system configurations to several computers. It is written mainly for the Debian distribution but should be portable (without too much difficulties) to other distributions or Unixes as well. It consists of a number of shell scripts to perform the desired actions. With it you can handle users, add ssh-public-keys, patch the system, update things using cfengine, install files (overriding other package files), and more.
DSM (Dedicated Server Manager) Standard is a solution for hosting companies and organizations who need to combine a Web server, mail server, DNS server, or a fully featured Web hosting environment. DSM Standard offers four levels of interface access: root user, reseller, site-owner, and mailuser.
Defaults Manager is an editor for the User Defaults preferences database on Mac OS X. It allows you to easily view, edit, delete, and backup preferences, and can be used to view and change the preferences in almost any application. It is useful for developers that want to make sure their preferences are being stored and changed correctly, and can be used to unlock features that previously required the use of Terminal.
DharmaDoc automates most of the tedious work involved in setting up a local Web server that contains a Buddhist reference library. The program allows you to download and install documents, and generates a search engine index. Afterward, you can just type your Buddhist topic of interest into a Web browser and get a wealth of information.
Driver On Demand is an automated driver installation system for Linux that automatically identifies devices that have no drivers and uses an online database to install an appropriate driver for that device without human interaction (if requested). This makes it an ideal system for newbies, as it takes away most of the configuration part of Linux. The goal is to allow users to plug in any device and have it instantly work without the need to manually install drivers.
The ESP Package Manager (EPM) is a simple tool that generates software and patch distributions in various formats, including AT&T software packages ("pkg") used by Solaris, Debian ("dpkg"), HP-UX software packages ("swinstall" or "depot"), IRIX Software Manager ("inst" or "tardist"), portable (installation and removal scripts with tar files), and Red Hat Package Manager ("RPM").
