Toxic is a general purpose template engine. It produces text output from different template input formats, such as text, XML, or SQL. New template formats can easily be integrated and even mixed. It is possible to use a text template format for attributes and text content in XML templates.
Magnetic Track Parser is a Java 7 library that can parse magnetic track data from a bank-issued credit card, such as might be returned from a USB magnetic card stripe reader. All classes are immutable and thread-safe. The standard toString() function formats data in a readable form. Validity is enforced by JUnit tests. Maven is needed for a build.
JS-Collider is an event-driven Java network NIO framework. It is designed to provide maximum performance and scalability for applications having not too many connections but significant amounts of network traffic (both incoming and outgoing). Performance and scalability are achieved via lock free algorithms and atomic states usage. It supports UDP (with multicast) as well. One of the implementation points is to avoid unsafe cheating; it should work the same way on all JVMs (Java 1.7). It supports shared memory IPC.
PAFCalc (Planted Aquarium Fertilizers Calculator) for Android is a useful utility that helps in calculations related to DIY fertilizers for planted aquariums. It has been completely written with the Android developer studio, which should ensure portability to tablets and smartphones. The app doesn't access any external functions on your device.
Vega is a GUI-based, multi-platform Web security scanner that can be used to find instances of SQL injection, cross-site scripting (XSS), and other vulnerabilities in your Web applications. It also includes an intercepting/scanning proxy for interactive Web application debugging and fuzzing.
io-util is a small, scalable Java library for slicing and dicing fixed width tables on disk. The objective is to provide reusable blocks of code for building efficient, custom binary data stores. It allows you to build, search, and maintain a large, externally stored, fixed width, sorted table. The library user specifies the row width (in bytes), a row comparison function (which implicitly defines any given row's key), and an optional delete codec.
RTextDoc is a text editor with proofreading. It is designed for typesetting professional research papers and manuals using the LaTeX, AsciiDoc, and DocBook markup languages. It includes on-the-fly spelling and grammar checking, syntax highlighting, bracket matching, folding, a document structure browser for sections and labels, bookmarks, a manager for LaTeX symbols, WYSIWYG equation editor, and integrated BibTex database manager.
