SHEF is an HTML editing framework and component for the Java Swing GUI library. It can be plugged into the javax.swing.JEditorPane text component, adding usable HTML WYSIWYG editing capabilities. In addition, it works around various JEditorPane quirks and adds functionality currently missing from the standard Swing text implementation. It includes an HTML source editor with syntax highlighting, context-sensitive Swing actions, unlimited undo/redo, table creation and editing, click+drag resizable tables, and click+drag resizable images. It is easily embeddable in Swing applications or applets.
libsysactivity is a lightweight library that retrieves statistics of the system's activity in a portable and thread safe way. In each OS that it supports, it offers the same API for retrieving the activity of Hard disks, CPUs memory, Processes, Network interfaces, Memory, and Swaps.
liblognorm is a tool to normalize log data. It takes logs in different formats as input and outputs the data within them in a single, consistent format. For example, if you have traffic logs from three different firewalls, liblognorm will be able to normalize all the events into a generic form. Among other features, it can extract source and destination IP addresses and ports and make them available via well-defined fields. The result is that a common log analysis application will be able to work on that common set independently from the actual firewalls feeding it. Even better, once a well-understood interim format exists, it is also easy to convert that into any other vendor specific format, so that you can use that vendor's analysis tool.
Libee is an event expression library that is inspired by the upcoming CEE standard. Right now, it provides capabilities to generate and emit messages in a set of standard formats and read a set of different input formats. Libee also comes with a handy conversion tool that provides format transformation without the need to program.
Libsonic is a free C library for speeding up or slowing down speech. However, it's optimized for speed-ups of over 2X, unlike previous algorithms for changing speech rate. Sonic enables clear playback of audio books at 3X speed, and some blind listeners are able to listen at 6X. Libsonic has also been integrated into several text-to-speech engines. It works well on all platforms, even Android phones without FPUs. Pitch control is also supported.
PascalSCADA is a framework for Delphi and Lazarus to quick development of HMI/SCADA applications. The platforms supported by PascalSCADA are Windows, Linux, and FreeBSD under 32 and 64 bits (FreeBSD only in 32 bits). You can communicate with CLP's, create interfaces, store values and alarms of process, and control users of the application.
Mathomatic is a portable, general-purpose computer algebra system (CAS) that can solve, differentiate, simplify, combine, and compare algebraic equations, perform standard, complex number, modular, and polynomial arithmetic, etc. It does some calculus and is very easy to compile/install, learn, and use. The symbolic math application with a simple command-line interface is designed to be a colorful algebra calculator that is reliable, responsive, and convenient to use. The symbolic math library is lightweight and easy to include in other software, due to being written entirely in C with no additional dependencies.
PHPLOT is a PHP graphics class for creating charts and plots. It works with PHP5 (but older versions can use PHP4). PHPlot uses the PHP GD extension to produce PNG, GIF, or JPEG images. TrueType fonts (TTF) are optional, or built-in GD fonts can be used. The available plot types are: area, bars, line/points, lines, pie, points, squared, stacked-bars, and thin bar-line. Labels, tick marks, plot legend, X/Y axes, and more are all configurable. Images can be imported as a background, multiple graphs can be drawn on one image, and images can be saved to disk or returned to a browser.
