Simple and intuitive 2D vector drawing for electronics and not only.
A multiplatform vector drawing program with a complete library of electronic symbols. Schematics and drawings are stored in a very compact text format. There is no netlist concept behind the drawings (so no simulation, and this is a choice) but this allows a great graphical flexibility and ease of use, making FidoCadJ the perfect tool for exchange sketches in forum and newsgroup discussions with a few clicks. Drawings can be exported in several graphic formats, such as pdf. Follow the development live on Twitter: https://twitter.com/davbucci
GridLAB-D is a new power system simulation tool that provides valuable information to users who design and operate electric power transmission and distribution systems, and to utilities that wish to take advantage of the latest smart grid technology. It incorporates advanced modeling techniques with high-performance algorithms to deliver the latest in end-use load modeling technology integrated with three-phase unbalanced power flow, and retail market systems. Historically, the inability to effectively model and evaluate smart grid technologies has been a barrier to adoption; GridLAB-D is designed to address this problem. User documentation can be found at: http://gridlab-d.shoutwiki.com/wiki/Quick_links The source code is available from GitHub. See https://github.com/gridlab-d/gridlab-d. Issue tracking is handled by GitHub. See https://github.com/gridlab-d/gridlab-d/issues.

Zhongwen Development Tool - helping to study Mandarin Chinese
The ZDT (Zhongwen Development Tool) is written in Java using the Eclipse RCP to help users study mandarin Chinese. The most important feature is the flashcard study feature. ZDT currently contains: * a Flashcard plugin for memorizing Chinese characters, their meaning and their pinyin/pronunciation. The user is able to import Character lists or enter them manually. This * a Dictionary search plugin with three dictionaries: ADSO, CeDict, HanDeDict. The HanDeDict is a German dictionary. It is also possible to search any word lists entered by the user using the flashcard plugin. * an Annotator plugin. The Annotator converts the Chinese characters into pinyin, using the Alphabet with accents. On the ZDT website, flashcard lists are available for some commonly used books, such as Hanyu Jiaocheng (汉语教程). User discussion can be found on: http://www.chinese-forums.com/index.php?/forum/35-zdt-flashcards-forum/ You also may choose to use Tickets -> Support (see above).
