documentr is a Web-based tool for editing and presenting software documentation. It allows you to easily maintain documentation for multiple products and product branches. Edits can easily be copied between branches, with merge conflicts being handled gracefully. It uses Markdown as its markup language, along with some extensions, and has a role-based permission system.
J2ObjC is a tool from Google that translates Java code to Objective-C for the iOS platform. It enables Java code to be part of an iOS build, as no editing of the generated files is necessary. The goal is to write an app's non-UI code (such as data access or application logic) in Java, which can then be shared by Web apps using GWT, Android apps, and iOS apps. J2ObjC supports most Java language and runtime features required by client-side application developers, including exceptions, inner and anonymous classes, generic types, threads, and reflection. JUnit test translation and execution are also supported.
LilacServer is a Web developed in Java that employs Java NIO technology. It is fast and highly productive. It is also a template engine with its own language for creating templates and a framework with its own API. More features of interest: built-in support for databases via JDBC; integrated localization facilities; sophisticated caching capabilities; support of sessions, multi-part forms, and file uploads; support of third-party libraries; a Web-based management interface; and so on.
Sirix is a versioned tree-based storage system. It provides Snapshot Isolation through MVCC and is best suited for flash-based storage. The tree encoding is suited for heavy update operations. It provides diffing algorithms either to import diffs between currently shredded (imported) XML documents to update a tree structure or to get the differences between versions of a tree structure. A GUI provides several visualizations for comparing imported tree structures.
mechanize is a stateful HTTP/HTML client library written in Java to be available on the JVM. It utilizes Apache HttpClient for HTTP handling and JSoup for HTML parsing. Because mechanize is stateful, it will by default support cookies and hidden form parameters (like Rails CSRF protection). This enables client code to follow links and behave like a RESTful hypermedia client more easily.
jMathLab is a platform for mathematical and numerical computations. It uses the Matlab/Octave programming language. It runs on any platform where Java is installed, and can also run on the Web browser. The following packages are included: symbolic calculations (simplification, differentials, integration), numeric calculations, evaluations of mathematical functions, special functions, linear algebra with vectors and matrices, plotting data and functions, saving data (vectors and matrices) in files, random numbers, statistics, and solving linear and non-linear equations
