Darik's Boot and Nuke (DBAN) is a self-contained boot floppy that securely wipes the hard disks of most computers. DBAN will automatically and completely delete the contents of any hard disk that it can detect, which makes it an appropriate utility for bulk or emergency data destruction.
Data::Locations is a virtual file manager which allows you to write and read data (text and binary) to and from virtual files (think of bubbles). Moreover, this manager allows you to (recursively) define "magic" insertion points in these virtual files (bubbles inside other bubbles) which can be filled in (inflated) later (through a "straw", i.e., the object's reference), at any convenient time and in any order you like. Since this software acts purely in memory, there is no slowing down through costly file input/output (i.e., no temporary files).
Davenport is a Java Servlet-based application providing WebDAV access to an entire SMB network. This enables users to connect to Windows and Samba shares via WebDAV clients such as Mac OS X, Windows Web Folders, etc. or any Web browser. Workgroups are browseable, and users are authenticated against a domain. WebDAV clients can upload, download, create directories, etc. Non-WebDAV clients (i.e., "normal" Web browsers) can also access the network of shares and download files. When run over HTTPS, this application provides a reasonably secure means of accessing an internal Windows/Samba network over the Internet without requiring a VPN.
Debian packaging utilities for Truecrypt source helps to get Truecrypt running with a minimum of effort under Debian-based Linux systems (Debian and Ubuntu are officially supported). Truecrypt is an open source disk encryption software which uses a concept of containers to store encrypted data. The containers (or volumes) can be read transparently under Linux and Windows. The utilities create installable *.deb packages from the sources and those debs can be used in turn to install the encryption software.

The dsnapshot script provides a high-level interface to the Linux Logical Volume Manager. It uses its block-level snapshot support to create directory snapshots. In contrast to block-level snapshots, directory snapshots resemble the file system layer. Thus, you can snapshot any directory that is on a logical volume without worrying about the actual logical volumes, mount points, and paths.
