SolarCalc is a program for estimating the solar radiation and electrical energy yield in a given site around the world. The software has been written in Qt and uses the most recent models of solar radiation conversion by PV effects. The software can take into account many aspects of solar systems such as detailed diffuse/beam correlation models, temperature effects, and shadowing effects. The system allows you to build a user-based archive of components, like solar panels and inverters. Many printing and exporting functions are available, as well as ready-to-use PDF report export.
The Java Wikipedia API (Bliki engine) is a parser library for converting Wikipedia/Mediawiki syntax to HTML. It supports wiki tags for bold, italic, headers, nowiki, source, table of contents, tables, lists, categories, footnotes (references), images, syntax highlighting of source code fragments, templates, and template parser functions.
SILGraphite (formerly OpenGraphite) is a project within SIL's Non-Roman Script Initiative and Language Software Development groups to provide extensible cross-platform rendering capabilities for complex non-Roman writing systems. It consists of a rule-based programming language, Graphite Description Language (GDL), that can be used to describe the behavior of a writing system, a compiler for that language, and a rendering engine that can serve as the backend of a text processing application. SILGraphite renders TrueType fonts that have been extended by means of compiling a GDL program. It is currently being integrated into Gecko/Mozilla through the SILA project, a GNU/Linux port is also underway, and there are plans for OpenOffice.org and Abiword integration.
Abbot is a framework for testing Java GUIs. It lets you launch an application or GUI component, play back user actions on it, and examine its state. Tests may be coded or scripted. The editor supports recording user actions into a script, exploring the component hierarchy, running the script, and other features you'd expect from a script editor. Test scripts are JUnit extensions.
