This book shows how to design and implement C++ software that is more effective: more likely to behave correctly more robust in the face of exceptions more efficient more portable makes better use of language features adapts to change more gracefully works better in a mixed-language environment is easier to use correctly is harder to use incorrectly. In short, software that s just better.

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.

"TR1 roughly doubles the size of the C++ standard library, and it introduces many new facilities and even new kinds of library components. TR1 has some classes, for example, where some nested types may or may not exist depending on the template arguments. To programmers whose experience stops with the standard library, this is strange and unfamiliar. This book is complete (it covers all TR1 facilities), it is easier to understand than TR1 itself, and it is technically accurate."

The iputils package contains ping, a basic networking tool. The ping command sends a series of ICMP protocol ECHO_REQUEST packets to as pecified network host and can tell you if that machine is alive and receiving network traffic.ipv6calc is a small utility which formats and calculates IPv6 addresses in different ways. It extends the existing address detection on IPv6 initscript setup or make life easier in adding reverse IPv6 zones to DNSor using in DNS queries like nslookup -q=ANY ipv6calc -r 3ffe:400:100:f101::1/48`

This player allows you to show the videos (FLV) in your websites with more controls and a broader audience as with QuickTime, Windows Media or Real Media. The FLV is now recognized as a fabulous format, using swf players to connect to the flv files by progressive download of streaming. This player is smaller and easier to adjust than the components in Flash.

Design patterns are elegant, adaptable, and reusable solutions to everyday software development problems. Programmers use design patterns to organize objects in programs, making them easier to write and modify. C# Design Patterns: A Tutorial is a practical guide to writing C# programs using the most common patterns. This tutorial begins with clear and concise introductions to C#, object-oriented programming and inheritance, and UML diagrams. Each chapter that follows describes one of twenty-three design patterns, recommends when to use it, and explains the impact that it will have on the larger design. The use of every pattern is demonstrated with simple example programs. These programs are illustrated with screen shots and UML diagrams displaying how the classes interact. Each of these programs is available on the companion CD-ROM and can be run, examined, edited, and applied.

It was proposed that perfect invisibility cloaks can be constructed for hiding objects from electromagnetic illumination (Pendry et al., Science 312, p. 1780). The cylindrical cloaks experimentally demonstrated (Schurig et al., Science 314, p. 997) and theoretically proposed (Cai et al., Nat. Photon. 1, p. 224) have however simplified material parameters in order to facilitate easier realization as well as to avoid infinities in optical constants. Here we show that the cylindrical cloaks with simplified material parameters inherently allow the zeroth-order cylindrical wave to pass through the cloak as if the cloak is made of a homogeneous isotropic medium, and thus visible. To all high-order cylindrical waves, our numerical simulation suggests that the simplified cloak inherits some properties of the ideal cloak, but finite scatterings exist.

In an electromagnetic cloak based on a transformation approach, reduced sets of material properties are generally favored due to their easier implementation in reality, although a seemingly inevitable drawback of undesired reflection exists in such cloaks. Here we suggest using high-order transformations to create smooth moduli at the outer boundary of the cloak, therefore completely eliminating the detrimental scattering within the limit of geometric optics. We apply this scheme to a non-magnetic cylindrical cloak and demonstrate that the scattered field is reduced substantially in a cloak with optimal quadratic transformation as compared to its linear counterpart.
