Drupal is a modular content management system, forum, blogging and community engine. It is database driven and can be used with MySQL, MariaDB, PostgreSQL, and SQLite. Its features include (but are not limited to) discussion forums, Web-based administration, theme support, a submission queue, content rating, content versioning, taxonomy support, user management with a fine-grained permission system based on user roles (groups), error logging, support for content syndication, locale support, and much more. It is considered to be an excellent platform for developers due to its clean code and extensibility, and it can also be used as a Web application framework.
Geeklog is the weblog software that concentrates on performance, privacy, and security. It features Web-based administration, surveys (polls), user-customizable boxes, a friendly administration GUI with a topic manager, an option to edit or delete stories, an option to delete comments, a search engine, backend/headlines generation (RSS/Atom format), calendaring, and much more.
Weasel Reader is an e-text reader for Palm OS. It is geared towards reading Project Gutenberg e-texts, but will work on any ASCII file. It uses zlib for compression, resulting in good file sizes, an important consideration for Palms. Weasel reads both zTXT (its own format) and PalmDoc files. It includes features such as bookmarks, annotations, categorization, searching, beaming, VFS access, and many display options. Also included is makeztxt, a command line program to generate zTXT databases. makeztxt supports regular expressions to automatically generate a list of bookmarks. Java and Perl/PHP versions of makeztxt are also available.
HickUP is a small multi-platform system for managing applications for a user or project environment. The user can, through a GUI or command line tool, choose which applications and versions they want to use. The project manager can specify allowed applications and versions of these the project members can select. The user can then select one of multiple environments to use at login or within a specific shell.
John the Ripper is a fast password cracker, currently available for many flavors of Unix, Windows, DOS, BeOS, and OpenVMS. Its primary purpose is to detect weak Unix passwords. It supports several crypt(3) password hash types commonly found on Unix systems, as well as Windows LM hashes. On top of this, lots of other hashes and ciphers are added in the community-enhanced version (-jumbo), and some are added in John the Ripper Pro.
KBiff is a KDE "biff" or new mail notification utility. It is highly configurable but very easy to use and setup. It supports session managment (it "remembers" the last state it was in before you logged off) and can be docked into the panel. It has support for mbox (Unix-style), maildir (qmail-style), mh, POP3, IMAP4, and NNTP mailboxes.
Lynx is a fully-featured WWW client for users running cursor-addressable, character-cell display devices (e.g., vt100 terminals, terminal emulators running on PCs or Macs, or any other character-cell display). It will display HTML documents containing links to files on the local system, as well as files on remote systems running HTTP, HTTPS, gopher, FTP, WAIS, NNTP, finger, or cso/ph/qi servers, and services accessible via logins to telnet, tn3270, or rlogin accounts.
climm (CLI-based Multi-Messenger) is a portable, small, yet powerful console-based ICQ and XMPP client. It supports password changing, auto-away, creation of new accounts, and other features that makes it a very complete yet simple client. It is able to send and receive messages from the ICQ network, list users that are offline and online (including their online status), search for users by email address, and look up basic (name, UIN, email) information. climm was formerly known as mICQ.
OBM is a groupware, email, LDAP, Windows PDC, CRM, and project management application. It is mainly used as a mail server, as an LDAP directory, as a Windows PDC, as a contact and customer database, as a project management tool, or as any combination of these functions. It supports internationalization and themes.
The stunnel program is designed to work as an SSL encryption wrapper between remote client and local (inetd-startable) or remote server. It can be used to add SSL functionality to commonly used inetd daemons like POP2, POP3, and IMAP servers without any changes in the programs' code. It will negotiate an SSL connection using the OpenSSL or SSLeay libraries. It calls the underlying crypto libraries, so stunnel supports whatever cryptographic algorithms you compiled into your crypto package.
