By Jim Blandy, Jason Orendorff

This useful ebook introduces platforms programmers to Rust, the hot and state-of-the-art language. You'll find out how Rust deals the infrequent and important blend of statically tested reminiscence security and low-level control—imagine C++, yet with no dangling tips, null pointer dereferences, leaks, or buffer overruns.

Author Jim Blandy - a former maintainer of GNU Emacs and GNU Guile - demonstrates how Rust has the capability to be the 1st usable programming language that brings some great benefits of an expressive smooth variety method to structures programming. Rust's ideas for borrowing, mutability, possession, and strikes as opposed to copies may be unexpected to such a lot structures programmers, yet they're key to Rust's special advantages.

This ebook provides Rust's principles sincerely and economically; elaborates on their effects; and indicates you ways to precise the courses you need to write in phrases that Rust can end up are freed from extensive sessions of daily mistakes.

By Erik Wischnewski

Mit diesem Buch wird Ihnen als Pascal-Einsteiger eine Hilfe an die Hand gegeben, mit der Sie Ihre ersten Anwendungen programmieren können. Aber auch als fortgeschrittener Anwender werden Sie zahlreiche assistance und tips finden, auf die Sie schon lange gewartet haben. Sie werden erstaunt sein, wieviel Ihnen geboten wird. Insgesamt finden Sie nicht nur - wie im Titel versprochen - a hundred, sondern sogar 103 wertvolle Rezepte für TurboPascal zusammengetragen. Jedes Rezept enthält außer einer nützlichen Prozedur oder Funktion auch ein inter­ essantes Anwendungsbeispiel, wie etwa trigonometrische Berechnungen, Umrechnungen von Temperaturen oder U-Boot versenken. Jedes Rezept bringt Ihnen einen vollen Lernerfolg. Sie werden nach wenigen Minuten bereits Ihre ersten Programme geschrieben haben. Sie können die Rezepte direkt als Bibliothek übernehmen oder auf Ihnen aufbauend eigene Anwendungen daraus gestalten. Zur Erhaltung der Übersicht wird nur das Wesentliche als Programmcode wiedergegeben. Im fortgeschrittenen Stadium gehen Programmierer im allgemeinen dazu über, möglicherweise auftretende Fehler abzufangen und zu bearbeiten. In diesem Büchlein wird bewußt darauf verzichtet, da anderenfalls der Umfang dreimal so groß geworden wäre. Es gibt nur wenige Ausnahmen, bei denen neben einer gekürzten model auch eine kompliziertere Vollversion als Rezept zu finden ist.

Download OpenGL ES 2.0 Programming Guide by Dave Shreiner, Dan Ginsburg, Aaftab Munshi PDF

By Dave Shreiner, Dan Ginsburg, Aaftab Munshi

OpenGL ES 2.0 is the industry’s major software program interface and photographs library for rendering subtle 3D pictures on hand-held and embedded units. With OpenGL ES 2.0, the total programmability of shaders is now on hand on small and conveyable devices—including mobile phones, PDAs, consoles, home equipment, and cars. even if, OpenGL ES differs considerably from OpenGL. images programmers and cellular builders have had little or no information regarding it—until now.

In the OpenGL® ES 2.0 Programming Guide, 3 major specialists at the Open GL ES 2.0 interface—including the specification’s editor—provide start-to-finish suggestions for maximizing the interface’s price in a variety of high-performance purposes. The authors conceal the whole API, together with Khronos-ratified extensions. utilizing certain C-based code examples, they show find out how to arrange and application each element of the pictures pipeline. You’ll circulate from introductory strategies all of the solution to complicated per-pixel lights, particle structures, and function optimization. 

Coverage includes:
* Shaders intensive: developing shader items, compiling shaders, checking for collect mistakes, attaching shader items to application gadgets, and linking ultimate application objects
* The OpenGL ES Shading Language: variables, kinds, constructors, buildings, arrays, attributes, uniforms, varyings, precision qualifiers, and invariance
* Inputting geometry into the photos pipeline, and assembling geometry into primitives
* Vertex shaders, their distinctive variables, and their use in per-vertex lighting fixtures, skinning, and different applications
* utilizing fragment shaders—including examples of multitexturing, fog, alpha try, and consumer clip planes
* Fragment operations: scissor try, stencil try out, intensity attempt, multisampling, mixing, and dithering
* complex rendering: per-pixel lights with common maps, surroundings mapping, particle platforms, snapshot post-processing, and projective texturing
