Wenity is a multi-platform Zenity clone that helps (shell) script writers to interact with their users through various types of GUI dialogs. Scripts call Wenity and receive the user's selection in the exit code/response file. It supports any operating system with Java and a GUI installed, supports complex return types by using response files, and has a modular architecture supporting different functions: simple dialogs (user input, information, question, error/warning), progress indicator dialogs, system tray notifications, file choosers, and file viewers (text and HTML).
Simple Workflow is a workflow engine. It is simple to use (you need to call only two methods and implement one interface), written in Java 7, uses a simple domain language to describe workflows, can be used with any storage backend (SQL, NoSQL, file, etc.), can be used with any frontend, and has a high level of backend/frontend abstraction.
Snippetsource is a simple yet powerful repository to store code snippets or any other text content. SQLite is used as the database backend, which makes fast indexed lookups possible. It is based on the editor of the Notepas project, so it will automatically benefit from the incremental changes happening on that project.
ivykis is a library for asynchronous I/O readiness notification. It is a thin, portable wrapper around OS-provided mechanisms such as /dev/poll, epoll_create(2), kqueue(2), poll(2), and port_create(3C). ivykis was mainly designed for building high-performance network servers, but can be used as building block for any kind of event-driven application that uses poll(2)able file descriptors as its inputs.
Dynace is a portable extension to the C language which adds object-oriented facilities, including classes with multiple-inheritance, a meta-object protocol, dynamic dispatching via generic functions, a garbage collector, threads, and an extensive class library, including an optional GUI library. It has complete documentation and a tutorial.
WinTariff is a program that collects and processes information about telephone calls. It receives data from an office PBX about the date/time, duration, and dialled number of phone calls, then calculates the cost of the call and determines the direction. Various reports about all calls during the month, calls to a certain internal subscriber, etc. can be generated. A data collection module is available for Linux/FreeBSD.
