The SNMP protocol was introduced in 1988. Overtime security had been added (1991-1992). Also several version improved versions have been published (SNMPv2[1] and SNMPv3[4]) The goal is to allow automation of network management by establishing a standard protocol supported by all network devices for configuration and monitoring.
Using SNMP enabled devices network administrators can automate the tedious and error prone task of changing the configuration of the network by using an administration interface which in turn will automatically re-configure each device on the network using SNMP. By having a unified protocol a single administration application can manage an entire network of heterogeneous devices.

In the late 1990’s many ERP companies caught the web browser wave, undertaking projects to leverage the Internet and browser technology and even to convert their software to “lite-client” or web “portal” architectures. Unfortunately for some, .NET came on the scene too soon after this major overhaul. When .NET appeared, some were too technically exhausted, or inflexible, or still basking in the glow of their new “Internet-based architectures” to recognize and embrace .NET. Other ERP software companies were and continue to be simply too busy struggling to stay solvent during the devastating one-two-three punch of Y2K, the recession of 2000, and 9/11. They lack the resources to consider the complete restructuring of their products that .NET warrants.

Delphi/400 is a suite of application modernization tools designed to enable System i application developers to build completely new Web applications or build new Web interfaces to existing applications. For the System/i developer, there is lots of good news. The approach is based on the same notion of holistic application design and user interface / logic separation that System i developers have been using since the box you and I love was once called the System/38 Delphi/400 is the toolset that best addresses the notion of the application factory of rapid application development. It is the natural next step in a progression of tools from those with sophisticated names such as “Intelligent Development Environment,” “Componentization,” and “Visualization.” Yes, It is all of those and more. It does its thing by asking the developer to think about the whole application, not just one Web page at a time. Isn’t that how System i developers already think?

The combination of evolving ICT standards that increase the interoperability between applications and the ever-increasing need for a more seamless access to and exchange of information is a major driver in the OECD ICT strategy. This paper describes the role and use of web services in the context of recent developments at the OECD to improve the accessibility of statistical information. It follows up on a paper presented at the 2002 ISIS meeting about “Improving Access to Statistical Information at OECD in Response to Users’ Requirements” and describes a technology framework – called “dot.STAT” – that has been devised for the implementation of applications that enable easy access to certain OECD reference data. The concepts outlined in this paper have been developed in close collaboration with the Statistics Directorate, specialised OECD-internal groups and task forces 2, as well as members of the SDMX Consortium3.

The EPICS toolkit consists of a set of software components with which Application Developers can create a control system. The basic component types are:
•OPI
Operator Interface. A UNIX- or NT-based workstation or PC which can run various EPICS tools—the “clients.”
•IOC
Input Output Controller. A VME/VXI-based chassis containing a Motorola 68K or PPC processor with various VME I/O modules for analog and digital signals, and for access to field buses such as Allen-Bradley, GPIB, CANbus or CAMAC.
•LAN
TCP/IP-based Local Area Network. A communication network which connects the IOCs and OPIs. EPICS provides a software com- ponent, Channel Access, which provides network transparent commu- nication between every client—such as OPI—and an arbitrary number of servers—such as IOC.

This tutorial teaches how to use the User modeling and profiling service (UMPS). UMPS provides the methodology to enhance the effectiveness and usability of services and interfaces in order to (a) tailor information presentation to user and context, (b) reason about user’s future behavior, (c) help the user to find relevant information, (d) adapt interface features to the user and the context in which it is used, (e) indicate interface features and information presentation features for their adaptation to a multi-user environment

Windows Presentation Foundation (WPF)
WPF provides a unified framework for building applications with rich user interfaces and interactivity. It is built on top of the .Net Framework and makes use of the managed and unmanaged code. WPF programming model allows the developers to write code once and deploy it as a standalone installed application or in a browser.

The Open-Source Physics project is a synergy of curriculum development, computational physics, and physics education research. One goal of the project is to make a large number of Java simulations available for education using the GNU Open-Source model. This manual describes some of the classes and interfaces that are being used in this project.
