Programming Web Services with XML-RPC introduces the simple but powerful capabilities of XML-RPC, a system for remote procedure calls built on XML and the HTTP protocol. XML-RPC lets developers connect programs running on different computers with a minimum of fuss, by wrapping procedure calls in XML and establishing simple pathways for calling functions. With XML-RPC, Java programs can talk to Perl scripts, which can talk to Python programs, ASP applications, and so on. Developers can provide access to functionality without having to worry about the system on the other end, so it's easy to create web services. This book supplies the details of both the XML-RPC specification and various XML-RPC implementations, so you can get started developing distributed applications in Java, Perl, Python, ASP, or PHP.

This new, leading-edge book offers you a comprehensive, in-depth presentation of GPRS (general packet radio service). The book helps you understand how this system is used as a major building block technology for the emerging mobile Internet. You explore the most critical aspects of GPRS in great detail, and gain a real-world understanding of the inevitable implementation challenges you will face in the field.

After a general overview of the GSM and GPRS systems, the book provides you with detailed coverage of a wide range of important topics, including the radio interface, Gb interface, BSSGP, signaling plane, user plane, and RLC (radio link control) principles. Case studies throughout present simple approaches to implementation problems that arise during the development process, along with proposed resolutions. This unique resource is an essential reference for engineers working in the field, and also serves well as a text for advanced graduate and post-graduate students in related courses.

Mobile Internet: Advanced Technologies and Services focuses on the migration of the Internet to the wireless world and discusses the relevant technologies and applications. The book discusses the concept of a wireless Internet, its benefits and challenges, and summarizes the relevant enabling technologies. It reviews particular problems which have to be addressed and general issues such as security, authentication, and mobility. The book illustrates the architecture and the key features of a wireless system capable of providing IP multimedia services. Moreover, the book studies the issues related to the TCP performance in wireless environments and demonstrates ways to improve this performance.

Make clones of some of the best applications on the Web using the dynamic and object-oriented features of Ruby

• Build your own custom social networking, URL shortening, and photo sharing websites using Ruby
• Deploy and launch your custom high-end web applications
• Learn what makes popular social networking sites such as Twitter and Facebook tick
• Understand features of some of the most famous photo sharing and social networking websites
• A fast-paced tutorial to get you up and running with cloning some of the most impressive applications available on the Web.

In Detail

Most users on the Internet have a few favorite Internet web applications that they use often and cannot do without. These popular applications often provide essential services that we need even while we don't fully understand its features or how they work. Ruby empowers you to develop your own clones of such applications without much ordeal. Learning how these sites work and describing how they can be implemented enables you to move to the next step of customizing them and enabling your own version of these services.

This book shows the reader how to clone some of the Internet's most popular applications in Ruby by first identifying their main features, and then showing example Ruby code to replicate this functionality.

While we understand that it connects us to our friends and people we want to meet up with, what is the common feature of a social network that makes it a social network? And how do these features work? This book is the answer to all these questions. It will provide a step-by-step explanation on how the application is designed and coded, and then how it is deployed to the Heroku cloud platform. This book's main purpose is to break up popular Internet services such as TinyURL, Twitter, Flickr, and Facebook to understand what makes it tick. Then using Ruby, the book describes how a minimal set of features for these sites can be modeled, built, and deployed on the Internet.

Break up and rewrite popular social networking and other Internet applications using Ruby

What you will learn from this book

• Discover in depth the major features of TinyURL, Twitter, Flickr, and Facebook and what makes them work
• Discover how each of these popular Internet services can be modeled with DataMapper
• Create clones of these Internet services using Rack and Sinatra
• Use third-party authentication providers with OpenID
• Deploy the cloned Internet services to the cloud using Heroku
• Use Amazon S3 to store data for your clones

Approach

This is a hands-on book with plenty of well - explained code. Each chapter has a standalone project in which a complete web application with specific features of a social networking site is emphasized. The final chapter of the book is a project that has a complete and fully developed social networking site. Each chapter begins with a brief description of the features of the Internet service and the market it is within. After extracting the main features of the service, the chapter goes into explaining how a clone of the service can be designed, followed by a short description of the technologies and platforms being used. The bulk of the chapter goes into describing how the clone is built, with step-by-step explanations and code examples. Finally, the chapter shows how the finished clone can be deployed on the Internet.

Who this book is written for

This book is written for web application programmers with an intermediate knowledge of Ruby. You should also know how web applications work and you have used at least some of the cloned Internet services before. If you are a trying to find out exactly how can you make your very own customized applications such as TinyURL, Twitter, Flickr, or Facebook, this book is for you. Programmers who want to include features of these Internet services into their own web applications will also find this book interesting.

If you don’t hack your systems, who will?

One of the reasons I put this book project together is that I believe security professionals should be hackers. In this case, by hackers, I mean people who are capable of defeating security measures. This book purports to teach people how to be hackers. In reality, most of the people who buy this book will do so because they want to protect their own systems and those of their employer. So, how can you prevent break-ins to your system if you don’t know how they are accomplished? How do you test your security measures? How do you make a judgment about how secure a new system is?

When you’re through reading Hack Proofing Your Network, you’ll understand terms like “smashing the stack,” “blind spoofing,” “building a backward bridge,” “steganography,” “buffer overflow” and you’ll see why you need to worry about them. You will learn how to protect your servers from attacks by using a 5-step approach:

1. Planning

2. Network/Machine Recon

3. Research/Develop

4. Execute Attack and Achieve Goal

5. Cleanup

And you’ll understand the theory of hacking, how to fend off local and remote attacks, and how to report and evaluate security problems.

The Only Way to Stop a Hacker Is to Think Like One.

This book describes the technologies involved in all aspects of a large networking system and how the various devices can interact and communicate with each other. Using a bottom up approach the authors demonstrate how it is feasible, for instance, for a cellular device user to communicate, via the all-purpose TCP/IP protocols, with a wireless notebook computer user, traversing all the way through a base station in a cellular wireless network (e.g., GSM, CDMA), a public switched network (PSTN), the Internet, an intranet, a local area network (LAN), and a wireless LAN access point. The information bits, in travelling through this long path, are processed by numerous disparate communication technologies. The authors also describe the technologies involved in infrastructure less wireless networks.
