Dynamic Probes (Dprobes) is a generic and pervasive system debugging facility that will operate under the most extreme software conditions such as debugging a deep-rooted operating system problem in a live environment. Dprobes allows the insertion of fully automated breakpoints or probepoints anywhere in the system and user space. Each probepoint has an associated set of probe instructions that are interpreted when the probe fires. These instructions allow memory and CPU registers to be examined and altered using conditional logic. When the probe command terminates, prior to returning to the probed code, a syslog record may be optionally generated.
DXSpider is a Ham Radio program that connects to other similar programs by radio or the internet and provides a real-time information service to Ham Radio operators rather like IRC. It is designed to become a complete replacement for the original DOS implementation written by Dick Newell AK1A.
DX0 is a PHP library that generates Dynamic HTML specific to the visitor's browser. DX0 focuses on generating tight, compact DHTML. DX0 allows reusable cross-browser widgets to be stored in a binary pickle, so scripters in any of the supported languages can use them. IE4+, NS4+, and Mozilla M14+ have all been tested and work well.
Dvipdfm is a DVI to PDF translator. Its features include TeX \special's that approximate the functionality of the PostScript pdfmarks used by Adobe Acrobat Distiller, the ability to include PDF files and JPEG files as embedded images, support for both Type1 and PK fonts, support for arbitrary linear graphics transformations, a color stack accessible via \special's, partial font embedding and stream compression for reduced output file size, native, portable graphics via TPIC \specials, balanced page and destination trees for improved reader access on very large document files.
dvgrab receives audio and video data from a digital camcorder via an IEEE 1394 (widely known as FireWire) link and stores them into an AVI file. It features autosplit of long video sequences into several files, and supports saving the data as raw frames, AVI type 1, AVI type 2, and image files.
