Conary is a distributed software management system for Linux distributions. It replaces traditional package management solutions (such as RPM and dpkg) with one designed to enable loose collaboration across the Internet. It enables sets of distributed and loosely connected repositories to define the components which are installed on a Linux system. Rather than having a full distribution come from a single vendor, it allows administrators and developers to branch a distribution, keeping the pieces which fit their environment while grabbing components from other repositories across the Internet.
JCons provides a library that bring color to your Java console. The Java console gives no methods to change the foreground or background color. With help of this library, one can make error messages red and success messages green, for example. Most Unix terminals can deal with ESC sequences, so they are used to make the Java console colorful.
TagEventor is a project to enable radically simple computer usage by creating physical-object-based user interfaces. It does this using commercially available (and relatively cheap), standardized RFID technology in the form of small, simple USB connected contacted card/tag readers and small, cheap tags. The project was started based on products available from the "touchatag" company, which has clients for Windows and Mac, and run their own Web service to enable many interesting Web-based applications. However, no simple, lightweight Linux client was available, and the Web focus meant that some client-focused functionality was not possible. The software is currently a daemon that monitors the presence of one or more RFID tags on a connected reader and generates "system events" when tags are placed on it or removed from it.
jniThreadCPUUsage is a Java library to get the amount of user and system CPU time used per thread. This is done via JNI, which calls getrusage() on the system. getrusage() is only available on Linux 2.6.26 or later and Solaris. One useful application of this is measuring the amount of CPU time used for a servlet request. getrusage() CPU time reporting is better than using the real time clock because it measures actual CPU time used and disregards times when the thread is idle or waiting (such as when it is waiting for network I/O).
Nit is a statically typed object-oriented programming language. The goal is to propose a statically typed programming language where structure is not a pain. It has a simple, straightforward style and can usually be picked up quickly, particularly by anyone who has programmed before. While object-oriented, it allows procedural styles. The Nit Compiler (nitc) produces efficient machine language binaries.
The Chameleon Problem Solving Environment is based on the CPACS data format and allows third party application coupling for multidisciplinary simulation. It comprises a set of libraries and integration components for the commercial integration environment ModelCenter or the open source alternative RCE (http://www.rcenvironment.de/). It was initially developed from the German Aerospace Center (DLR).
TIXI is a fast and simple XML interface library for applications written in C, C++, Fortran, Java, and Python. Although simplified and somewhat restricted compared to a fully-fledged XML processing library, it can create documents, create and delete nodes, and add and remove element attributes. Routines for reading and writing text nodes and nodes holding integer and floating point numbers are included, along with routines that process aggregates of these simple types for the processing of geometric data, multidimensional arrays, or arrays of vectors.
The TIGL Geometry Library can be used for easy processing of geometric data stored inside CPACS data sets. TIGL offers query functions for the geometry structure. These functions can be used, for example, to detect how many segments are attached to a certain segment, which indices these segments have, or how many wings and fuselages the current airplane configuration contains. This functionality is necessary because TIGL targets not only the modeling of simple wings or fuselages but also the description of quite complicated structures with branches or flaps. The library uses the OpenCASCADE software to represent the airplane geometry by B-spline surfaces in order to compute surface points and also to export the geometry in the IGES/VTK format. The library provides external interfaces for C, C++, Python, Java, and FORTRAN.
