Scalable Vector Graphics. Scalable Vector Graphics (SVG) is an XML-based vector image format for two-dimensional graphics with support for interactivity and animation.

Scalable Vector Graphics

The SVG specification is an open standard developed by the World Wide Web Consortium (W3C) since 1999. SVG images and their behaviors are defined in XML text files. This means that they can be searched, indexed, scripted, and compressed. As XML files, SVG images can be created and edited with any text editor, but are more often created with drawing software. Overview[edit] This image illustrates the difference between bitmap and vector images. SVG has been in development since 1999 by a group of companies within the W3C after the competing standards Precision Graphics Markup Language (PGML, developed from Adobe's PostScript) and Vector Markup Language (VML, developed from Microsoft's RTF) were submitted to W3C in 1998.

Hibernate Best Practices. IDictionary Options - Performance Test - SortedList vs. SortedDictionary vs. Dictionary vs. Hashtable. Please note that the advantage of Hashtable over generic Dictionary for insert and search operations demonstrated here is actually because the tests are based on NON generic IDictionary interface, so each insert or search action is accompanied with check for the key type.

IDictionary Options - Performance Test - SortedList vs. SortedDictionary vs. Dictionary vs. Hashtable

For more information see the Sean's comment below. (Thanks Sean!) Without that Dictionary seem to perform better than the Hashtable. The rest of the test conclusions will not be affected. So to summarize, generic Dictionary is the absolute winner for insert and search operations if used with generic dictionary interface or directly. C# Reference. Open Source Rule Engines in C# Implementation Issues of Authorization Mechanisms in Grid Computing Systems. This paper analyzes the requirement of authorization service for grid computing systems and proposes the use of threshold closure as a basic mechanism for implementing authorization service in grid computing systems. While pointing out the desirable features of threshold closure for complex authorization policies, the paper also discusses the practical limitations of threshold closure in such an environment, and then puts forward a new authorization service for virtual organization.

In addition, an access control protocol which is based on PKI is designed in the paper. By segregating the policy and mechanism aspects of threshold closure, the new service can use existing security infrastructure in grid computing system while keep the ability to express complex authorization policy effectively. XAML Overview (WPF) XAML is a declarative markup language.

XAML Overview (WPF)

As applied to the .NET Framework programming model, XAML simplifies creating a UI for a .NET Framework application. You can create visible UI elements in the declarative XAML markup, and then separate the UI definition from the run-time logic by using code-behind files, joined to the markup through partial class definitions. XAML directly represents the instantiation of objects in a specific set of backing types defined in assemblies. This is unlike most other markup languages, which are typically an interpreted language without such a direct tie to a backing type system. Enterprise Integration Patterns - Messaging Bridge. An enterprise is using Messaging to enable applications to communicate.

Enterprise Integration Patterns - Messaging Bridge

However, the enterprise uses more than one messaging system, which confuses the issue of which messaging system an application should connect to. How can multiple messaging systems be connected so that messages available on one are also available on the others? Use a Messaging Bridge, a connection between messaging systems, to replicate messages between systems.

Typically, there is no practical way to connect two complete messaging systems, so instead we connect individual, corresponding channels between the messaging systems. Windows Workflow Foundation Overview. Windows Workflow Foundation is a framework that enables users to create system or human workflows in their applications written for Windows Vista, Windows XP, and the Windows Server 2003 operating systems.

Windows Workflow Foundation Overview

It consists of a namespace, an in-process workflow engine, and designers for Visual Studio 2005. Windows Workflow Foundation can be used to solve simple scenarios, such as showing UI controls based on user input, or complex scenarios encountered by large enterprises, such as order processing and inventory control. Windows Workflow Foundation comes with a programming model, a rehostable and customizable workflow engine, and tools for quickly building workflow-enabled applications on Windows.

Scenarios that Windows Workflow Foundation addresses include: Demos - APE (Ajax Push Engine) Build a Google IG like AJAX Start Page in 7 days using ASP.NET AJAX and .NET 3.0. Chapter 1. Using Spring AMQP. Chapter 1.
