Flightdeck-UI is a project that utilizes the ideas in the design of aircraft controls and instruments for creating general purpose user interfaces. The project includes Flightdeck-UI Online (a Web-based monitoring system that works entirely through the browser), the Multi-Variable Monitor (MVM) application, and a Tkinter widget library. Flightdeck-UI Online is installed on a Web server. The MVM application provides a graphical editor with theme support for quickly creating Flightdeck-UI control panels. It is possible but not necessary to write code in order to use MVM.
Xapian is a search engine library, scalable to collections containing hundreds of millions of documents. It's written in C++ with bindings for Perl, Python, PHP, Java, Tcl, C#, Ruby, and Lua. It is a highly adaptable toolkit that allows developers to easily add advanced indexing and search facilities to their own applications. It supports the Probabilistic Information Retrieval model and also a rich set of boolean query operators. Omega is a Web search application built upon the Xapian library. It can index a Web server's document tree (including HTML, PDF, OpenOffice, MS Word/Excel/Powerpoint/Works, WordPerfect, RTF, PS, etc.), or data exported from arbitrary sources (e.g. SQL databases).
