FeatureC++ is a C++ language extension that supports Feature-Oriented Programming (FOP). FOP studies feature modularity in program families. The idea of FOP is to build software by composing features. Features are basic building blocks that satisfy intuitive user-formulated requirements on the software system. Features refine other features incrementally. This step-wise refinement leads to a layered stack of features. Mixin Layers are one appropriate technique for implementing features.
GenFoo is a general Fokker-Planck solver for models of arbitrary dimensionality. It contains three backend solvers, a delta-f Monte Carlo, a standard Monte Carlo, and a Finite Element solver. The key property of the GenFoo package is that physics are separated from numerics by runtime loading of the Fokker-Planck coefficients, which enable solutions of a large class of Fokker-Planck models.
yacts, yet another continuous time simulator, uses J+ to interpret scripts, defining systems of ordinary differential equations, which it solves. J+ is a functional non-imperative simulation language with lazy evaluation, based on the J programming language, a dialect of APL. A program in J+ is a collection of (possibly functional) J assignment statements, just like a set of formulae on a sheet of paper. The interpreter, implemented as a software library, knows the interdependencies between these formulae and is able to compute any of the defined quantities with minimal effort, keeping track of the values which were already computed. The driver program (such as yacts) may ask the interpreter to compute certain quantities and set the values for others (propagating the changes to dependents).
QtitanChart is a Qt.C++ library that represents a set of controls that allow you to quickly and easily provide your application with beautiful and colorful diagrams. It is implemented in pure Qt. Adding it to your program requires only a few lines of code, and the architecture allows you to customize every part of the charts. it supports point, line, step line, clustered column, stacked column, pie, doughnut, аrea, and stacked area charts with full interactivity. A rich set of themes is included, and real time charts are supported.
RealOpInsight is an advanced dashboard management toolkit for Nagios, Zabbix, Zenoss, Icinga, and other common open source monitoring systems including GroundWork, Centreon, Shinken, and op5 Monitor. It provides effective features for monitoring in demanding operations environments such as network operations centers and large data centers.
OpenSAND, formerly known as Platine, is a user-friendly and efficient tool to emulate satellite communication systems, mainly DVB-RCS - DVB-S2. It provides a suitable and simple means for performance evaluation and innovative access and network techniques validation. Its ability to interconnect real equipments with real applications provides excellent demonstration means.
