DirectX not only provides fast access to the hardware and therefore incredibly speedy performance, but it also makes it much easier for hardware developers to produce new devices that work well in the Windows environment. The DirectX APIs take away the necessity of writing your own low-level, device-specific code to access hardware such as the display adapter and network card, making it much easier for you to write programs that take full advantage of the computer s multimedia capabilities.
手機與服務器通過SyncML進行同步的客戶端框架以及API,用戶可以基于此框架快速開發j2me版本的syncML客戶端。
The Funambol SyncML API allows application developers to embed SyncML capabilities in a J2ME
application, thus giving it the access to a powerful data synchronization framework to keep the application
data in sync with other devices.
The PCI Local bus concept was developed to break
the PC data I/O bottleneck and clearly opens the door
to increasing system speed and expansion capabilities.
The PCI Local bus moves high speed peripherals
from the I/O bus and places them closer to the system’s
processor bus, providing faster data transfers
between the processor and peripherals. The PCI Local
bus also addresses the industry’s need for a bus standard
which is not directly dependent on the speed,
size and type of system processor. It represents the
first microprocessor independent bus offering performance
more than adequate for the most demanding
applications such as full-motion video.

Libvirt是一套在linux上用C編寫的虛擬化操作工具接口。其目的是提供一個穩定的支持Xen,QEME和KVM虛擬化平臺的C(也支持Python) API
Libvirt is a C toolkit to interact with the virtualization capabilities of recent versions of Linux (and other OSes).The library aim at providing long term stable C API initially for the Xen paravirtualization but should be able to integrate other virtualization mechanisms, it currently also support QEmu and KVM.
The core of Java(TM) technology, the Java virtual machine is an abstract computing machine that enables the Java(TM) platform to host applications on any computer or operating system without rewriting or recompiling. Anyone interested in designing a language or writing a compiler for the Java virtual machine must have an in-depth understanding of its binary class format and instruction set. If you are programming with the Java programming language, knowledge of the Java virtual machine will give you valuable insight into the Java platform s security capabilities and cross-platform portability. It will increase your understanding of the Java programming language, enabling you to improve the security and performance of your programs.
Matlab is an ideal tool for simulating digital communications systems, thanks to
its easy scripting language and excellent data visualization capabilities. One of the
most frequent simulation tasks in the field of digital communications is bit-error-
rate testing of modems. The bit-error-rate performance of a receiver is a figure of
merit that allows different designs to be compared in a fair manner. Performing
bit-error-rate testing withMatlab is very simple, but does require some prerequisite
knowledge
PHP Cookbook has a wealth of solutions for problems that you ll face regularly. With topics that range from beginner questions to advanced web programming techniques, this guide contains practical examples -- or "recipes" -- for anyone who uses this scripting language to generate dynamic web content. Updated for PHP 5, this book provides solutions that explain how to use the new language features in detail, including the vastly improved object-oriented capabilities and the new PDO data access extension. New sections on classes and objects are included, along with new material on processing XML, building web services with PHP, and working with SOAP/REST architectures. With each recipe, the authors include a discussion that explains the logic and concepts underlying the solution.
