Download E-books KDE- und Qt-Programmierung, 2., aktualisierte Auflage . GUI-Entwicklung für Linux PDF

By Burkhard Lehner

Eines der erfolgreichsten Projekte der Linux-Welt ist sicherlich der laptop KDE: In vielen Sprachen benutzbar, hat er Anwendern den Einstieg in die Linuxwelt erleichtert und so zur Beliebtheit des freien Betriebsystems beigetragen. KDE basiert auf der Bibliothek Qt der norwegischen Firma Troll Tech., die zusammen mit C++-Programmierung die KDE-Entwicklung ermöglicht.

In der Reihe Linux Specials dieses Handbuch für Einsteiger und für fortgeschrittenere KDE-Entwickler erschienen. Auf etwa 500 Seiten führt Burkhard Lehner sowohl in die Programmierung mit Qt 1.44 als auch der unter einer neuen Lizenz veröffentlichten model 2.0 ein.

Lehners Handbuch beginnt für Einsteiger mit dem obligatorischen "Hello global" und führt zunächst in die Grundkonzepte der Qt-Programmierung für KDE ein. Die Basisklassen QObject und QWidget werden ausführlich behandelt. Der Einstiegsteil führt weiter zur Programmierung so unterschiedlicher Gebiete wie Grafikprimitive, Sound oder Internationalisierung und Mehrsprachigkeit, eine der netten candies bei KDE. Kompliziertere Konstrukte wie die Netzwerkprogrammierung für KDE und das Session-Management werden ebenfalls nicht vernachlässigt. Der vorletzte Abschnitt beschreibt Werkzeuge zur Programmentwicklung für KDE und eine ausgewählte Referenz von KDE- und Qt-Klassen.

Das Handbuch schließt mit einem Abdruck der unterschiedlichen Linux- und KDE-relevanten Lizenzen von GPL bis QT Public License. Es enthält eine ausgewogene Mischung von Erklärungen und Programmbeispielen, die mit Übungsaufgaben abgerundet sind. (Die Lösungen finden sich ebenfalls am Ende des Buches.) Lehners Handbuch ist intestine geschrieben und liest sich verständlich und flüssig. Gerade Einsteiger, die allerdings C++ können sollten, finden hier viele Hinweise und Erklärungen zu den KDE/Qt zugrundeliegenden Konzepten. Für die herannahende neue model von KDE und dem hoffentlich baldigen Erscheinen von KOffice und nicht zuletzt aufgrund der neuen Lizenz von Qt 2.0 sollten Einsteiger auf die Unterschiede zwischen Qt 1.44 und Qt 2.0 achten, die Lehner dankenswerterweise ebenfalls untergebracht hat.

Die beiliegende CD enthält sowohl die Qt-Bibliothek 1.44 als auch 2.0.1, das KDE-SDK, unterschiedliche Werkzeuge zur Programmentwicklung und KDE 1.1.1. --Susanne Schmidt

Download E-books High Performance Parallel I/O (Chapman & Hall/CRC Computational Science) PDF

By Prabhat, Quincey Koziol

Gain severe perception into the Parallel I/O Ecosystem

Parallel I/O is an necessary element of sleek excessive functionality computing (HPC), in particular in storing and processing very huge datasets to facilitate clinical discovery. Revealing the state-of-the-art during this box, High functionality Parallel I/O attracts on insights from major practitioners, researchers, software program architects, builders, and scientists who make clear the parallel I/O ecosystem.

The first a part of the booklet explains how large-scale HPC amenities scope, configure, and function platforms, with an emphasis on offerings of I/O undefined, middleware, and functions. The booklet then traverses up the I/O software program stack. the second one half covers the dossier method layer and the 3rd half discusses middleware (such as MPIIO and PLFS) and user-facing libraries (such as Parallel-NetCDF, HDF5, ADIOS, and GLEAN).

Delving into real-world medical purposes that use the parallel I/O infrastructure, the fourth half provides case reports from particle-in-cell, stochastic, finite quantity, and direct numerical simulations. The 5th half supplies an summary of varied profiling and benchmarking instruments utilized by practitioners. the ultimate a part of the booklet addresses the results of present tendencies in HPC on parallel I/O within the exascale world.
