LogicalDOC is a Web-based document management system that is easy to use and learn. Its architecture leverages best-of-breed Java technology to achieve a powerful and flexible solution. It supports its users with a powerful search engine (Lucene), Web service interface (JAX-WS via CXF) compatible with .NET and PHP, versioning, annotation on documents, a WebDAV interface, importing and exporting from .zip files. Documents can be organized into hierarchical folders, searched using the integrated search engine, or browsed by Tag. The system is extensible thanks to the technologies used (Spring-Hibernate) and its plugin architecture.
The GNU Gatekeeper is a free H.323 gatekeeper based on the OpenH323 project. You can use it to manage a Voice-over-IP network and let endpoints (e.g., Netmeeting) communicate through symbolic names. It also has an external interface for billing and other applications. It runs on a number of Unix versions (including Linux and Solaris) and Windows.
FLTK (pronounced "fulltick") is a cross-platform C++ GUI toolkit for UNIX/Linux (X11), Microsoft Windows, and Mac OS X. It provides modern GUI functionality without the bloat, and supports 3D graphics via OpenGL and its built-in GLUT emulation. FLTK is designed to be small and modular enough to be statically linked, and also works fine as a shared library. It also includes an excellent UI builder called FLUID that can be used to create applications in minutes.
DB Solo is a powerful database development and management tool for developers and DBAs. It has an intuitive user interface that allows you to explore and manage your database objects as well as execute ad-hoc queries. It supports Oracle, MySQL, Sybase, DB2, Solid, PostgreSQL, and MS SQL Server. In addition to viewing and managing objects such as schemas, tables, indexes, views, tablespaces, users, roles, sessions, and stored procedures, you can view, edit, print, and export data from tables or the results of queries. You can also graphically view foreign key relationships.
Vim is an almost fully-compatible version of the Unix editor Vi. Many new features have been added including multi-level undo, syntax highlighting, commandline history, online help, filename completion, and block operations. It is descended from the vi clone "stevie" and runs on many systems, including Unix, MS Windows, OS/2, Macintosh, VMS, and Amiga.
libextractor is a library used to extract meta-data from files of arbitrary type. It is designed to use helper-libraries to perform the actual extraction, and to be trivially extendable by linking against external extractors for additional file types. The goal is to provide developers of file-sharing networks, file managers, and WWW-indexing bots with a universal library to obtain meta-data about files. It includes a shell-command and bindings for Java (JNI) and Python.
