Kurzbeschreibung

Capturing a wealth of experience about the design of object-oriented software, four top-notch designers present a catalog of simple and succinct solutions to commonly occurring design problems. Previously undocumented, these 23 patterns allow designers to create more flexible, elegant, and ultimately reusable designs without having to rediscover the design solutions themselves.

The authors begin by describing what patterns are and how they can help you design object-oriented software. They then go on to systematically name, explain, evaluate, and catalog recurring designs in object-oriented systems. With Design Patterns as your guide, you will learn how these important patterns fit into the software development process, and how you can leverage them to solve your own design problems most efficiently.

Each pattern describes the circumstances in which it is applicable, when it can be applied in view of other design constraints, and the consequences and trade-offs of using the pattern within a larger design. All patterns are compiled from real systems and are based on real-world examples. Each pattern also includes code that demonstrates how it may be implemented in object-oriented programming languages like C++ or Smalltalk.

Dieser Titel ist in englischer Sprache.
In Zeiten, in den sich Technik immer schneller fortentwickelt, kann man nur noch selten einzelne Bücher als Pflichtlektüre bezeichnen: zu kurz ist die Halbwertzeit. Entwurfsmuster. Elemente wiederverwendbarer objektorientierter Software ist genau einer dieser Klassiker, die unverzichtbare Lektüre für jeden Programmierer sind, der unter Verwendung von Objekten Software entwickelt. Diese CD-ROM enthält eine Hypertext-Version des Buches, zusammen mit zusätzlichen Funktionalitäten, die die Verwendung von Entwurfsmustern in eigenen Programmen stark vereinfachen.

Die CD-ROM funktioniert mit jedem javafähigen Browser, also zum Beispiel mit dem Internet Explorer 4.0 oder dem Netscape Communicator 4.5). Man erhält den kompletten Text der gedruckten Ausgabe, aber durch Hyperlinks angereichert. So kann man wahnsinnig schnell navigieren und noch effizienter mit Entwurfsmustern arbeiten. Durchdacht ist dabei, daß gleich zwei Versionen des Textes vorliegen: Eine für eine Bildschirmauflösung von 640x480 Pixeln, eine für höhere Auflösungen -- der mobile Einsatz auf einem Notebook vor Ort macht damit keine Probleme.

Entwursmuster sind Entwürfe höherer Ordnung, die immer wieder in obektorientierten Designs vorkommen. Das Herz dieses Titels ist der Muster-Katalog, der aus 23 grundlegenden Entwurfsmustern besteht. Auf der CD-ROM wird die Funktion jedes einzelnen Elements eingehend besprochen und Gründe für dessen Benutzung genannt. Außerdem gibt es immer Beispiel-Code in Smalltalk und C++. Das ist auch das Angenehme an dieser CD-ROM-Version: daß man einfach nur Copy&Paste machen muß, um die Beispiele gleich in seiner Software weiterzunutzen. Mit der Java-Suchmaschine auf der CD-ROM kann man schnell nach Stichworten suchen, und auch die Querverweise machen das Arbeiten sehr bequem.

Alles in allem ist die Design Patterns CD eine ansprechende neue Version eines der wichtigsten Bücher über objektorientierte Programmierung.

Design Patterns is based on the idea that there are only so many design problems in computer programming. This book identifies some common program-design problems--such as adapting the interface of one object to that of another object or notifying an object of a change in another object's state--and explains the best ways (not always the obvious ways) that the authors know to solve them. The idea is that you can use the authors' sophisticated design ideas to solve problems that you often waste time solving over and over again in your own programming.

The authors have come up with some ingenious ways to solve some common vexations among object-oriented programmers. Want to build a page-layout program that embeds inline images among characters of various sizes? How about building a program that converts files of one format to another? Chances are, some programmer already has thought of a better solution than you will and the recipes you need are here. Solutions are presented in generalised diagrams of data and logic structures. The idea is that you can take the concepts presented here and adapt them--in whatever language you use--to your individual situation. You may have to read some of the chapters several times before you fully understand them, but when you find a solution in this book, it will make your job easier and your results more elegant. --Jake Bond

With the profusion of technologies, it's rare to say that a particular book is required reading for developers. Design Patterns: Elements of Reusable Object Oriented Software is one of those indispensable texts for anyone who develops software using objects. This CD-ROM edition contains a hypertext version of the book, along with additional features that make it easy to use patterns in your own programs.

The CD-ROM works with any Java-enabled browser (Internet Explorer 4.0 and Netscape Communicator 4.0.) It includes the full text of the printed book along with the richness of hypertext links to get the most out of patterns quickly. (Two versions of the text, one for 640 x 480 resolution and one for higher resolutions, are provided.)

Patterns are higher-order designs, which occur repeatedly in object-oriented design. The heart of this title is the "pattern catalog" of 23 basic patterns, ranging from creational patterns, such as Factory and Builder, and structural patterns, such as Facade and Flyweight, to behavioral patterns, such as Command and Mediator. The CD-ROM details each design element along with reasons to use it and sample code in Smalltalk and C++. (With the online version, you can even cut and paste sample code into your programs.) You can use the Java search engine to search the CD-ROM for keywords, and the online version lets you cross-reference patterns easily. All in all, the Design Patterns CD is an appealing new version of one of the most essential texts for object-oriented developers.

Blogs are supposed to be the magic bullet for online business. 

Whether you?re a professional blogger, or your blog is built to buoy your regular business, you?re pressing publish for one primary reason: To build, engage, and nurture a ginormous audience. Not just big and ginormous ? an audience so massive, you?re virtually guaranteed a flood of customers wide enough that your rivers of online revenue will never stop flowing. 

At least that?s how it?s supposed to work. 

Yet, the vast majority of blogs trudge along with an Alexa ranking soaring north of a million, with their authors seemingly screaming down an empty online hallway as the echo of their voices slowly fades amid the chirping crickets and digital tumbleweeds.
It wasn?t supposed to be this hard. You must be doing something wrong, or maybe missing something obvious. You search for help, but instead of answers you find yourself skidding along a slippery path littered with snake oil and bombastic claims:

Make $500 in just one hour with our no-fail system!
How I Make $4,729.19 every week (while never changing out of my pajamas)
Tired of Losing? Beat any competitor to the front page of Google

The siren call is alluring, yet you can see the jagged rocks in the distance.  

If it?s so easy to make $500 in an hour, why are they selling the system for $27, rather than hiring teams of people to do all the work and make them the money? 

What if your competitor buys the same course ? how fast will she knock you off of that top spot? Why do they always detail the amount down to the last decimal? 

You?re skeptical, but hopeful. It seems like everyone is growing a giant site in no time, just not you. What?s their secret?

You open your wallet, carefully sidestepping the ?results not typical? disclaimers. You sift through the nonsense, find a few kernels of solid advice, then diligently put them to work. But you find nothing but more crickets and tumbleweeds; maybe a scant handful of new visitors.

This is exhausting, but you don?t have to do it anymore. How to Build a Blog cuts through the crap and shows you why the guru strategies don?t always work, and how you can follow an A-B-C strategy that will. 

It might not be easy, but it is possible. And ?How to Build a Blog,? shows you exactly how with proven, tangible examples that you can start following tomorrow.
