Securing Web 2.0: are your web applications vulnerable?The definition of Web 2.0 is still being debated despite extensive discussion. Its staunchest advocates proclaim it a complete philosophical and technological reworking of how the web functions. Others declare that it is meaningless. However, most agree on common characteristics of a Web 2.0 application, such as increased interactivity, the acceptance of user input for building community and a reliance on client-side functionality. Additionally, Web 2.0 applications can be more vulnerable to exploitation by hackers than their predecessors. Hackers spend most of their time gathering information. When Web 2.0 applications push functionality and code to users, they provide hackers with information that can be used for formulating attacks. Often, old attacks such as cross-site scripting become more dangerous when used against Web 2.0 applications. This white paper defines some of the common technological components of Web 2.0 applications and discusses ways of securing them against exploitation.
Web 2.0 components
Web 2.0 uses the web for delivering information that is often created through community contribution. Wikis and blogs are good examples of these types of appli cations. The main attribute of a Web 2.0 application is interactivity. More functionality is on the client, and less is on the server. As a result, requests are updated in the browser without refreshing the entire page. For example, consider Google Maps. Instead of a static page, you can drill down or zoom in and out of a map without making requests for a new page. You can use several key technologies—or more appropriately, groupings of differentClassroom Suite Access QuickStartClassroom Suite is accessible to keyboard, mouse, IntelliKeys, and switch users.
IntelliKeys
IntelliKeys is IntelliTools’ award-winning adaptive keyboard that connects to Windows or Macintosh computers. The original IntelliKeys was created in 1991. IntelliKeys USB was introduced a decade later. Both IntelliKeys models (Classic and USB) offer a range of access settings to meet the needs of people with various disabilities. Access settings can be customized for individual students. IntelliKeys is most powerful and versatile when used with IntelliKeys overlays.
IntelliKeys Overlays
The IntelliKeys keyboard works in conjunction with interchangeable IntelliKeys overlays. An overlay is a printed sheet of paper or plastic that is placed over the touch sensitive, front panel of the IntelliKeys. Each overlay has a keyboard layout printed on it that may correspond to an on-screen document. Simply insert the appropriate overlay and begin working. Pressing a printed key on the overlay sends the desired information to your computer. Using overlays, a student can type letters, enter numbers, navigate on-screen displays, or execute menu commands. A teacher can also customize IntelliKeys access settings for a student using the IntelliKeys USB Control Panel or Setup Overlay.
IntelliKeys for Switch Users
IntelliKeys has two built-in, programmable switch ports allowing the IntelliKeys to be used as a switch interface. Many commonly used switches can be plugged into these jacks. In addition, the keyboard itself can behave as a two-key keyboard, thus replicating the actions of two switches. One switch area (one key) covers the entire left side of the IntelliKeys touch-sensitive surface, while a second switch areaGetting Started with Maya TutorialViewing the Maya 3D scene Introduction Camera tools Workflow overview Viewing objects in shaded mode Grouping objects The Hypergraph Selection modes and masks Pivot points Save your work Beyond the lesson Lesson 4 Components and attributes Introduction Template display Components The Attribute Editor Surface materials Save your work Beyond the lesson Getting Started with Maya 4 Table of Contents 3 Polygonal Modeling Introduction Preparing for the lesson Lesson 1 Modeling a polygonal mesh Introduction Setting modeling preferences

Depending on which port(s) your computer has, you can connect the GT 050Q in a number of ways. You’re probably already familiar with FireWire 400 and USB, so we’ll tell you a little about FireWire 800 and eSATA.
FireWire 800 Facts
• FireWire 800 supports speeds up to 800 Mb/sec, twice as fast as FireWire 400.
• If your computer does not have built-in FireWire 800, you'll need a PCI card to achieve a true FireWire 800 connection.
• Most 800 ports are Bi-Lingual, which means they speak both FireWire 400 and FireWire 800.
• If you connect a 400 device to an 800 device, you will be running at 400 speed maximum.
• FireWire is forward-compatible and back-compatible, but the bus always runs at the speed of the slowest link.
• Beta cables are used to connect 800 devices to 800 devices.
• Bi-Lingual cables are available to connect 400 devices to 800 devices.
• Bi-Lingual cables have a 9-pin Bi-Lingual connector at one end and a 4-pin or 6-pin FireWire 400 connector at the other end
eSATA Facts
• eSATA is an external interface technology that grew from the internal SATA I interface.
• The GT 050Q’s eSATA port supports speeds up to 1.5 Gb/sec (150 MB/sec), much faster than FireWire 400 or FireWire 800.
• Shielded eSATA cables up to 2 meters in length are available.
• eSATA cables are different than SATA I cables, they are shielded and cannotProgramming in CSharp pdfCSharp is designed for the .NET framework. The .NET framework is object oriented. CSharp has a great set of tools for the object oriented programmer. CSharp is the first component oriented language in the C/C++ family. Component concepts are first class:
Properties, methods, events Design-time and run-time attributes integrated documentation using XML CSharp can be embedded in web pages. In C++ and Java primitive date types (int, double, etc) are magic and do not interoperate with objects. In Smalltalk and Lisp primitive types are objects, but at great performence cost. CSharp unifies this with no performance cost. CSharp also adds new primitive data types, for example decimal. Collections work for all types.
In CSharp, private is the default accessibility. The accessibility options are:
public - accessible to all
private - accessible to containing class
protected - accessible to containing or derived classes
internal - accessible to code in same assembly
protected internal - means protected or internal
Classes can be marked as public or internal. By default classes are private.

In learning to use a CAD system, lines and circles are the first two, and perhaps the most important two, geometric entities that we need to master Copyrighted the skills in creating and modifying. Straight lines and circles are used in almost all technical designs. In examining the different types of planar geometric entities, we can see that triangles and polygons are planar figures bounded by straight lines. Ellipses and splines can be constructed by connecting arcs with different radii.
As we gain some Material experience in creating lines and circles, similar procedures can be applied to create other geometric entities. In this lesson, we will examine the different ways of creating lines and circles in AutoCAD® LT 2006.

PICPgm is very good open source software for Windows. Works well with Windows 98, XP and Vista. It supports even our JDM based programmer circuit. Here is a Screenshot of the software as you open it (without connecting any hardware circuitry).
Now, if you just connect the Programmer Hardware PCB (without the actual PIC Microcontroller IC placed on it) to the Serial Port of the Computer CPU (through a Serial Port Connection Wire), and press the ‘Autodetect Programmer Hardware’ Button … you will get to see the type of Programmer Hardware, as follows:
Now additionally, if you place any 40?pin PIC Microcontroller IC (belonging to the 16F or 18F Series) on the zip socket, and press the ‘Autodetect PIC Type’ button … you will get to see the IC Number.
(You can also program a non?40?pin PIC IC using the external pin connector, instead of using the zip?socket)
