A name server is a network service that enables clients to name resources or objects and share this information with other objects in the network.
SolarCalc is a program for estimating the solar radiation and electrical energy yield in a given site around the world. The software has been written in Qt and uses the most recent models of solar radiation conversion by PV effects. The software can take into account many aspects of solar systems such as detailed diffuse/beam correlation models, temperature effects, and shadowing effects. The system allows you to build a user-based archive of components, like solar panels and inverters. Many printing and exporting functions are available, as well as ready-to-use PDF report export.
The ANSI/ISO C++ specifcation includes a standard C++ library, also known as the STL. GCC by default comes with an implementation that does not comply with this standard, but instead partly implements an older version. STLport is a freely available implementation, based on the SGI STL implementation. It is fully-compliant, supported, and very fast. It includes special debugging facilities and interesting and useful extensions to the standard.
