When iOS SDK was released to the public, because of the nature of hardware and software used in iOS devices, developers immediately recognized the amazing power in these devices and started to write games for the iPhone and now for the iPad. Developers had to write custom code to manage gamers? scores, manage leaderboards, initiate multiplayer games and etc. With the introduction of Game Center, a framework built into the iOS SDK, developer can take advantage of all the features of Game Center built into the core of iOS SDK. Features such as: leaderboards, user authentication, achievements, multiplayer games and etc. Game Center is a quite new framework to iOS.

There are many students and professionals in science and engineering, other than those specifically interested in fields such as computer science or computer engineering, who need to know how to solve computational problems on computers. There are basically two approaches to meeting the needs of such people. One is to rely on software applications such as spreadsheets, using built-in functions and perhaps user-defined macros, without requiring any explicit understanding of the principles on which programming languages are based. A second approach is to learn a programming language, previously Fortran or Pascal, and more recently C, C++, or Java. These languages are important for certain kinds of work, such as computer science or scientific computing, but they may be viewed, possibly with good reason, as irrelevant by many students and professionals. From a student’s point of view, there is no painless solution to this dilemma, but in this book I assume that learning to solve computational problems in an online environment using HTML,1 JavaScript, and PHP will at least appear to be a more relevant approach. HTML and JavaScript are universally used for developing self-contained online applications. The use of PHP for accessing externally stored data files, a capability that is not available directly through JavaScript, greatly extends the range of science and engineering problems that can be addressed. A working knowledge of these programming languages is a valuable skill for any scientist or engineer. The fact that these are Web-based languages may make such skills more immediately marketable than comparable skills developed with older text-based languages.

HTML5: Everyone’s using it, nobody knows what it is. I realize that sounds more like a line out of an existential movie — maybe Waiting for Godot or a screenplay by Sartre — than a statement about HTML5. But it’s really the truth: most of the people using HTML5 are treating it as HTML4+, or even worse, HTML4 (and some stuff they don’t use). The result? A real delay in the paradigm shift that HTML5 is almost certain to bring. It’s certainly not time to look away, because by the time you look back, you may have missed something really important: a subtle but important transition centered around HTML5.

PHP is the engine behind millions of dynamic web applications. Its broad feature set, approachable syntax, and support for different operating systems and web servers have made it an ideal language for both rapid web development and the methodical construction of complex systems. One of the major reasons for PHP’s success as a web scripting language is its origins as a tool to process HTML forms and create web pages. This makes PHP very web-friendly. Additionally, it is eagerly promiscuous when it comes to external applications and libraries. PHP can speak to a multitude of databases, and it knows numerous Internet protocols. PHP also makes it simple to parse form data and make HTTP requests. This web-specific focus carries over to the recipes and examples in the PHP Cookbook. This book is a collection of solutions to common tasks in PHP. We’ve tried to include material that will appeal to everyone from newbies to wizards. If we’ve succeeded, you’ll learn something (or perhaps many things) from PHP Cookbook. There are tips in here for everyday PHP programmers as well as for people coming to PHP with experience in another language. PHP, in source code and binary forms, is available for download for free from http://www.php.net/. The PHP web site also contains installation instructions, comprehensive documentation, and pointers to online resources, user groups, mailing lists, and other PHP resources.

上一篇介紹到由 Client 端提出連線(connect)的請求後,Server 端這邊剛好也正處於傾聽(Listening)狀態中,因此當Server 端收到了Client 端的連線請求後,Server 端會決定是否要接受連線,此時會使用到accept()這個功能呼叫;其實這中間牽扯到了很重要的3-way handshaking(連線三步曲)的TCP/IP 概念,不懂的人請自行參閱相關書籍.

首先我們先來介紹 socket()這個功能呼叫;當一個網路軟體要開始與在另一端上的網路軟體進行資料的交換時,要先開啟一個通訊用的端點,透過這個通訊端點,兩端間的網路軟體才可互相進行資料的交換.

首先我們先以 TCP(連結導向)的網路連線建立過程來作說明Client 與Server 端間會用到的一些功能呼叫(Function Call),底下我們列出了這些功能呼叫之間的相互關係.

最近由於工作繁忙及本人懶散因素,所以一直沒由撰寫什麼新文章,不過最近到了各大書局閒逛了一圈下來,卻發覺了介紹Winsock 的書籍可以說是寥寥無幾,所以興起了分享我的Winsock 程式設計經驗給予大家的念頭,希望能就我所學與大家一同學習,如文中內容有誤,請不吝予以指導!癈話不多說,進入主題啦!

我们认为 Perl 是一种容易学习和使用的语言，而且我们希望能证明我们是对的．Perl 比较简单的一个方面是你用不着在说想说的东西之前先说很多其他东西。在很多其他编程语言里，你必须首先定义类型，变量，以及你需要用到的子过程，然后才能开始写你要执行的第一行程序。虽然对于那些需要复杂数据结构的复杂问题而言，声明变量是一个好主意.但是对于很多简单的日常问题，你肯定喜欢这样的一种编程语言

在 2004 年三月，Java 开发者年度大会宣布了由其读者选择的最佳Java 组件年度奖结果，超过15,000 位开发者投票选举诸多Java 工具套件（当然包括不少声名显赫的供应商如Oracle 和Apple 等）之一。但最终，Eclipse 的标准小部件工具套件轻易地击败诸多强手，如同其在2003 年一样赢得了年度最佳。 虽然 Eclipse 是Java 开发领域的迟到者，但其同样在JavaWorld, JavaPro 和LinuxWorld 社区获得了荣耀。一路而来如潮的掌声和好评彰显了Eclipse 对于Java 开发的巨大冲击和影响。在过去的每一天，全球的Java开发者们不断被SWT 和JFace 强劲的功能和部署新插件和独立应用程序的能力所折服。 虽然我们都知道SWT 和JFace 是工具（套件），但更科学地讲它们是软件类库。它们由包含java 类和接口的文件包组成。但又是什么使得这些组件能让你任意组合GUI 呢？你的应用程序可以快速运行，高效运用计算机内存并有着和操作系统界面相同的界面体验，没有其他的GUI 构建体系可以如此。虽然SWT 和JFace 实现了相同的功能，但它们产生用户界面的机理却是迥然不同的。 我们试图通过汽车驱动机理来类比这一情况：SWT 开发就像标准的汽车驱动模式，它给了你更多的控制权力，并有机会接触系统内部的东西，但是其使用是相当复杂的；而JFace 情况下，就像是汽车的自动驱动模式，你不必深入太多，但是你丧失了灵活性。当然，实际情况肯定比这个比喻要更为复杂。所以我们需要更进一步的讨论这两个类库。

The greatest single reason that the World Wide Web has been so widely used and adopted is because individuals are allowed to participate in the Web. People can produce web content and create a MySpace page or home pages provided by their school or organization and contribute their creativity and content to the Web. Free services like Blogger, Flickr, Google Sites, Google Groups, and others have given us all an outlet for our creativity and presence on the Web—at no charge. For most of the life of the Web, if you wanted to have your own rich software-backed website with data storage, your only choice was to purchase hosting services from an Internet Service Provider (ISP) and learn database management and a programming language like PHP to build or run your software. Learning and paying for this much technology was just beyond the reach of most web users, who simply had to accept the limited features of MySpace, Blogger, or whatever system hosted their web content. In April 2008, Google announced a product called App Engine. When you write a program for the Web that runs on App Engine, your software runs on the Google servers somewhere in the Google “cloud.” It is as if you are a Google employee and you have access to the entire scalable Google infrastructure. App Engine captures much of Google’s experience of building fast, reliable, and scalable websites, and through App Engine, Google is revealing many of the secrets about how its own applications scale to millions of users. The most exciting part of the Google App Engine announcement is the fact that it is free for moderate levels of use. Every person with a Gmail account can have a number of free applications running on the Google infrastructure. If your application becomes extremely popular and your traffic goes above the allowed levels of the free account, you can pay to use more of Google’s resources. As your application scales, Google engineers and operations staff take care of all the hardware, data storage, backup, and network provisioning for you. The cost of purchasing resources from Google’s cloud of servers is likely far less than purchasing/renting/maintaining the same amount of resources on your own. Google focuses on providing hardware and network; you focus on building your application and the user community around your application.

I first met Julie Lerman (rhymes with “German”) while she was visiting the Microsoft campus for a Software Design Review (SDR). An SDR is an event where we invite customers we trust to be representative of a much larger crowd. In this particular case, I was new to the SQL Server division and trying hard to catch up on the raft of technologies Microsoft shipped in the data space for developers. Julie, on the other hand, was a seasoned veteran and not only knew the answers to all of my Entity Framework questions but had already written a book on the topic. That book, Programming Entity Framework, was the first edition of the book you’re now holding in your hands. Or, if you are a .NET programmer, you know it simply as “THE book on EF.”
