DragonFly belongs to the same class of operating systems as other BSD-derived systems and Linux. It is based on the same Unix ideals and APIs and shares ancestor code with other BSD operating systems. DragonFly is differentiated from other operating systems in its class by, among others, the HAMMER file system, Virtual Kernels, swapcache, and the pervasive use of soft token locks. DragonFly provides an opportunity for the BSD base to grow in an entirely different direction from the ones taken in the FreeBSD, NetBSD, and OpenBSD series.
Dim is a utility to help you track the changes of items (sets composed of multiple files). It provides commands to handle the complete lifecycle of version control operations: create a library, register users (code authors), create items, save local versions, branch, clone, export, import, remove, merge, archive, replicate library content over the network or the filesystem, and access the full history and browse differences at the library, item, file, line, or word level. Dim is a single self-documented POSIX shell script. It just uses standard Unix utilities like awk, diff, tar, and openssl.
Werc is a minimalistic RESTful Web application framework and content management system. It follows the Unix "tool philosophy" and it is designed to be fast, simple, convenient, and easily extensible. It handles both small and big sites and has a flexible system for user and group permissions. All data is stored in plain text files that can be easily manipulated with standard tools, without using any databases or other external dependencies. Existing applications include a blogging engine with RSS/Atom feeds, a wiki system that can easily integrate pre-existing documents (can be enabled for any directory tree), and others.
LMDBG is a collection of small tools for collecting and analyzing the logs of malloc/realloc/memalign/free function calls. Unlike many others, LMDBG does not provide any way to detect overruns of the boundaries of malloc() memory allocations, as this is not the goal. Like most other malloc debuggers, LMDBG allows detecting memory leaks and double frees. However, unlike others, LMDBG generates full stacktraces and separates the logging process from analysis, thus allowing you to analyze an application on a per-module basis.
UnifiedSessionsManager is a unified and simplified interface for the use and management of local and remote sessions on physical and virtual machines. It provides management of distributed and stacked virtual machines, management of desktops and workspaces on multiple monitors, seamless access to all types of sessions, and support of encrypted connections using SSH.
Newfangle is a literate programming technique for LyX (or LaTeX) inspired by notangle. It comes in two parts. The weave part that produces the formatted document is implemented entirely in LaTeX, and the tangle that generates the source code is implemented in awk for portability. Naturally, newfangle is written using literate programming techniques, using itself, and so the source is also the documentation. The source is written using the LyX document editor, an excellent front end to LaTeX. LyX is not required, but newfangle provides formatting support for LyX. Literate programming makes you write good code, because if you can't write a good justification or explanation for your code, it makes you think again and write something that you can explain.
pwgrep is a simple password manager that manages a database file using encryption of GnuPG. It uses encryption and version control on all of the passwords that are stored. The password database can be used on several hosts at once with automatic synchronization. Even several users can share the same password database. The versioning system will keep track of who was changing which entries and at which time. The versioning system to use can be configured (and is Subversion by default). Besides passwords, pwgrep can also be used for storing a collection of files like certificates. The file shredding command for secure deleting of temporary files can be configured. A local backup of all database changes is automatically made. It can be used without a GUI (such as through an SSH session).
