It is released separately as a stand-alone chapter. Here, we discuss the role of the next generation SIM (Subscriber Identity Module) card, referred to as SCWS (Smart card web server) SIM within Mobile Web 2.0. To explain the background, this document includes other sections from the book so that it becomes as complete document in itself.
Synopsis and key ideas
The key ideas behind this chapter are:
• Web 2.0 has already evolved to Cloud computing.
• Inspite of the notion of a ‘Web only’ processing, the cloud needs a client (as is now apparent from the deployment of a browser like Chrome from Google).
• For a mobile ecosystem, there are two possibilities for a Cloud client; The device or The SIM since both are at the edge of the network(for simplicity we discuss a cellular network only i.e. not Wimax, WiFi etc)
• From a network Operator perspective, the SCWS SIM offers a possibility to be the client for the mobile cloud for reasons that we discuss in this chapter.
• The SCWS SIM technology also offers the possibility of accessing mass market devices.
Notes:
1) This chapter is written from a Telecom Operator perspective. There are other implementations of Mobile Web 2.0 which are non Operator specific
2) We use the term SCWS technology to refer to Smart Card Web Server technology and SCWS SIM as the next generation SIM card incorporating SCWS technology
Web 2.0 and MobileVirtools: How to create interactive textures and an orbital cameraThis tutorial shows how to create behaviors for interactive textures: scrolling, blending textures on the faces of a cube. We will work on one face of the cube with its specific material-shader and one texture “mountain.jpg”. Part 4 of this tutorial covers setting up an orbital camera.
Part 1- In Maya, exporting a cube with textures
Before exporting to Virtools, make sure that all faces inside the cube have their normals facing towards the inside of the cube. Go to Modeling, Display > Polygon Components > Normals
Normals are represented with colored lines sticking out of the faces of the cube.
The red arrow shows the way one normal should look like.
The red arrow indicates a normal that needs to be reversed.
Go to Modeling, Edit Polygons > Normals > Reverse
Creating a database Resource folder:
Open Virtools and create a Resource database, go to Resource > create New Data Resource Folder, name of your choice and save in the location of your choice. Virtools automatically creates a Resource.rsc file and a Resource folder which contains several subfolders. The file called Resource.rsc is used to open the database Resource folder in Virtools. This folder is independent from the composition that you will later create in Virtools. It can be used to exchange assets between projects.

While web applications have become larger and more complex, web application developers today have little visibility into the end-to-end behavior of their systems.
This paper presents AjaxScope, a dynamic instrumentation platform that enables cross-user monitoring and just-in-time control of web application behavior on end-user desktops. AjaxScope is a proxy that performs on-the-fly parsing and instrumentation of JavaScript code as it is sent to users’ browsers. AjaxScope provides facilities for distributed and adaptive instrumentation in order to reduce the client-side overhead, while giving fine-grained visibility into the code-level behavior of web applications. We present a variety of policies demonstrating the power of AjaxScope, ranging from simple error reporting and performance profiling to more complex memory leak detection and optimization analyses. We also apply our prototype to analyze the behavior of over 90 Web 2.0 applications and sites that use large amounts of JavaScript.
In the last several years, there has been a sea change in the way software is developed, deployed, and maintained. Much of this has been the result of a rise of software-as-a-service paradigm as opposed to traditional shrink-wrap software. These changes have lead to an inherently more dynamic and fluid approach to software distribution, where users benefit from bug fixes and security updates instantly and without hassle. As our paper shows, this fluidity also creates opportunities for software monitoring. Indeed, additional monitoring code can be seamlessly injectedCryptanalysis of Microsoft’s Point-to-Point Tunneling Protocol (PPTP)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.
Many organizations and institutions are not centralized. Branch offices, virtual corporations, and traveling employees make the notion of running dedicated network connections to each location logistically impossible. The concept of virtual networking provides a solution to this problem by tunneling cojoined network space over other, transitory and insecure, networks (such as the Internet), thus enabling remote locations to appear to be local. This is done without the expense incurred from running leased lines or dedicated cabling to each location, and is sometimes called a “tunnel.”
While virtual networks solve the problem of de- centralized machines, they create a new problem. They open up traffic that was previously considered internal to the company, to any prying eyes on the networks it traverses. Authentication and encryption are required to keep this virtual network traffic not only tamperproof but private. The result, virtual networking connections combined with cryptographic protections, is a Virtual Private Network (VPN).
The security of a VPN is based on the security of its authentication and encryption protocols. If a VPN’s cryptography is weak, then its security is no better than a non-private virtualMiniview IOGear G-CS12/14 2/4 KVM Port Switch Owners Manual GuideIOGEAR’s KVM switches are first-rate connectivity accessories designed to help reduce the frustration of managing multiple computer systems. With the MiniView series by IOGEAR, you can access multiple computers from a single console (keyboard, mouse and monitor). The MiniView provides two convenient methods to access connected computers. Change ports easily via the push button selection switch located on the unit’s side panel, or by entering Hot Key combinations from the keyboard. Setup is fast and easy; plugging cables into their appropriate ports is all that is entailed.
There is no software to configure, no installation routines and no incompatibility problems. Since the MiniView intercepts keyboard input directly, it works on any PS/2 compatible hardware platform and with all operating systems. There is no better way to save time and money than with a MiniView . By allowing a single console to manage the attached computers, the MiniView eliminates the expense of purchasing a separate keyboard, monitor and mouse for each PC. Additionally, these switches save all the extra space multiple consoles would take up, and eliminate the inconvenience and wasted effort involved in constantly having to move from one PC to the other.

Antiquated manual switches have given way to intelligent devices, which boast new features that increase reliability and productivity. system. Another feature you might want to consider is the KVM switch’s ability to pass a high-resolution video signal without signal degradation.
With so many KVM choices available, you can narrow your options by deciding how many devices you need to switch among, how many concurrent users you need to connect (and the distance of those users from the main console), and the maximum video resolution you’ll use. Most devices employ programmable hot keys for switching, but make sure that the device you select has at least one key sequence that doesn’t conflict with another function in your organization. If you need to support many systems, you’ll most likely need to cascade multiple KVM switches. In that case, look at how clean the cascading process is for both implementation and operation. In addition to the device’s features, you need to consider form factor, cable quality, and ease of use..

But unlike symbolic AI, they “ground” the symbols in the data: the symbols have meaning in terms of data, not just meaning imposed by the outside user. If neural nets could be made to grow their own symbols in the way that brains do, there would be a good prospect of combining neural networks and symbolic AI, in such a way as to combine the good features of each.
It is argued that the secret of growing symbols in neural nets lies in cluster analysis. Algorithms for clustering, many of them naturally implementable in neural hardware, would produce clusters, which are discrete entities summarising data that have all the properties of symbols.
The war between symbolic artificial intelligence and its neural net rival continues because each has strengths that the other lacks, and it has proved impossible to combine them successfully. It is agreed that symbolic systems work well on discretely structured problems, like chess, and give a transparent understanding of what they are doing, which allows their use in new situations through adding and deleting rules. But it is difficult to make them adaptive to data, especially in situations where there is only data to go on, and almost no understanding via rules, such as face recognition. Scaling up from toy to real problems is also hard. Neural nets, on the other hand, are strong where symbolic AI is weak, and vice versa. They adapt easily
