This chapter presents a few of the thousands of mashups you can find today on the Web. No one knows how many other mashups live behind corporate firewalls, but, chances are, the number is large. The mashups in this chapter were chosen to show the variety of the world of mashups. Some of them are proofs-of-concept, others are works-in-progress, and others are experiments. Others are actual, live products or marketing tools. Mashups often provide visualization of information, and, frequently, that visualization is in the form of interactive maps. The release of the Google maps API was a major factor in the interest in mashups, in large part because so much information lends itself to mapping. As you will see in later chapters of this book, new technologies grouped together as Web 2.0 and AJAX are the building blocks of mashups. In conjunction with APIs such as Google mapping, eBay, Yahoo!, Flickr, and others, you will soon be able to build your own mashups like the ones shown in this chapter.

This paper presents the results of a study on the leverage of web 2.0 technology and open business models to expand service providers’ IMS and SDP (Service Delivery Platform) and offer new services and service composition capabilities for existing business partners such as MVNO, ISV, ASPs but also sophisticated end users, so called “prosumers”. We have collected the requirements from different users and customers which were all converging to an expansion of existing environment to offer a much more ‘internet’ like service offering : simple APIs, mix of content and communication capabilities, graphical composition tools, open portal, widgets, developer communities, easy to share, try and comment set of services, etc. Based on that, we did an evaluation of different tools and technology and defined an architecture that could meet these expectations while leveraging existing IMS-SDP environments and built a proof of concept.

The Point-to-Point Tunneling Protocol (PPTP) is used to secure PPP connections over TCP/IP links. In this paper we analyze Microsoft’s Windows NT implementation of PPTP. We show how to break both the challenge/response authentication protocol (Microsoft CHAP) and the RC4 encryption protocol (MPPE), as well as how to attack the control channel in Microsoft’s implementation. These attacks do not necessarily break PPTP, but only Microsoft’s implementation of the protocol.

Unisys and Microsoft collaborated on a proof of concept to demonstrate that the Microsoft SQL Server 2005 product suite will support even the most demanding enterprise business intelligence initiatives. The proof of concept shows that SQL Server 2005 can deliver the same or better results for a high-performance enterprise-class data warehouse than the more-costly alternatives.

Current tools to analyze memory dumps of systems running Microsoft Windows usually build on the concept of enumerating lists maintained by the kernel to keep track of processes, threads and other objects. Therefore they will frequently fail to detect objects that are already terminated or which have been hidden by Direct Kernel Object Manipulation techniques.

This talk is all about writing performant code, not the other kinds of monstrosities that you might regard as crap code. We’ll leave obfustucated code to the Perl programmers, C# isn’t very good at it. Managed languages such as C# are often criticised for being slower than their counterparts such as C++. Often these claims are unfounded. I’ve worked on several projects where performance has been a problem and often people don’t understand why their code is running slowly. Typically they’ll blame the .NET runtime as the problem’s obvious there rather than in their own code. So what sort of performance pitfalls await the unwary? Inspired by the concept of proof by contradiction I decided to take a program and ignore Microsoft best-practises to see “How Slow It Could Go.”

The BlueBag Project Current Bluetooth worms pose relatively little danger compared to Internet scanning worms—but things might change soon. The authors’ BlueBag project shows targeted attacks through Bluetooth malware using proof-of-concept codes and devices that demonstrate their feasibility. In this article, we focus on the new risks created by the widespread presence of Bluetooth-enabled devices carrying both potentially sensitive data and vulnerability-prone software. In particular, we show how this mix of technologies could become a vehicle for propagating malware that’s specifically crafted to extract information from smart phones.
