Authoring an EnterpriseDB report with Report Builder 2.0

by Jayaram Krishnaswamy | June 2009 | Open Source

This article by Dr. Jayaram Krishnaswamy shows step-by-step how you may retrieve data from a database on a Postgres Plus server and display the results in a report generated using Report Builder 2.0. Report Builder 2.0 is a report building and maintaining tool provided with SQL Server 2008. The evaluation version of SQL Server 2008 Enterprise edition was used in this tutorial. Report data is obtained via an ODBC DSN. The connection uses an EnterpriseDB ODBC driver that gets installed on the computer when EnterpriseDB is installed.

Authorizations in SAP HANA

by Mark Walker | July 2013 | Enterprise Articles SAP

In this article by Mark Walker, author of Software Development on the SAP HANA Platform, we will examined the fact that some of your users might not be allowed to have access to all the data in the system, or might have specific rights, maybe to create data but not to see the data that is currently in the system. We'll see concrete example of access restrictions on both objects and their content in this article.

SAP HANA provides several different layers of security from which you can benefit, and in this article we'll be looking at each of them. We'll examine how we can create each type of object, how they interact with each other, and how we can use them.

The authorization concept in SAP HANA is comprised of different notions:

  • Roles

  • SQL privileges

  • Analytic privileges

  • System privileges

  • Package privileges

  • Users

     

We will take a look at each of these concepts in turn.

Authorizing User Access to BPEL Process

by Matjaz B. Juric | October 2010 | Enterprise Articles Web Development

In the previous article, Securing a BPEL process, we saw the principles of securing BPEL processes.

In this article, by Matjaz B. Juric, author of WS-BPEL 2.0 for SOA Composite Applications with IBM WebSphere 7, we will look at how to secure BPEL processes, so that they can be accessed only by authenticated users. In a nutshell, we will:

  • Configure the web service export of a BPEL process to propagate user identity to the process, so that a process instance ownership can be claimed in that user's name
  • Protect a BPEL process at SCA level as a component to implement access to the process for authorized users only

Automated testing using Robotium

by Hrushikesh Zadgaonkar | November 2013 | Open Source

Automated testing helps us to maintain high software quality and provides a facility to capture if any code changes affect the actual use case. This article by Hrushikesh Zadgaonkar, the author of Robotium Automated Testing for Android, introduces the Robotium framework, its different features, its benefits in the world of automated testing, the API set of the Robotium Framework, and how to implement the Robotium Remote Control using SAFS.

Automating the Audio Parameters – How it Works

by Chris Khoo | September 2013 | Open Source Web Development

In this article by Chris Khoo, the author of Instant Audio Processing with Web Audio, we will see how automating the audio parametes is carried out. There are several key rules in regards to scheduling the automation events:

  • If an event is added at a time when there is already an event of the exact same type, the new event replaces the old one.

  • If an event is added at a time when there is already an event of a different type, it is scheduled to occur immediately after it.

  • Events may not overlap – some events occur over time, such as the linearRampToValueAtTime() automation behavior. No events may be scheduled in the time when such events are active, otherwise Web Audio will throw a runtime exception.

Automating Your System Administration and Deployment Tasks Over SSH

by Dr. M. O. Faruque Sarker | March 2014 | Cookbooks Networking & Telephony

In this article, by Dr. M. O. Faruque Sarker, author of Python Network Programming Cookbook, we will cover the following recipes:

  • Executing a remote shell command using telnet
  • Copying a file to a remote machine by SFTP
  • Printing a remote machine's CPU information
  • Installing a Python package remotely
  • Running a MySQL command remotely

This article promotes some interesting Python libraries. The recipes are presented aiming at the system administrators and advanced Python programmers who like to write code that connects to remote systems and executes commands. The article begins with lightweight recipes with a built-in Python library, telnetlib. It then brings Paramiko, a well-known remote access library. Finally, the powerful remote system administration library, fabric, is presented. The fabric library is loved by developers who regularly script for automatic deployments, for example, deploying web applications or building custom application binaries.

Automation with Python and STAF/STAX

by Javier Collado | September 2008 | Open Source

The aim of this article by Javier Collado is to show how tasks may be automated using Python together with STAF (Software Testing Automation Framework) by means of an example. We will first see a problem and then derive its solution using classical Python-only as well as Python+STAF. The implementation of the solution will evolve in different stages. This will help us in comparing both the solution in terms of simplicity and efficiency.

Autoscaling with the Windows Azure Service Management REST API

by Neil Mackenzie | August 2011 | Cookbooks Enterprise Articles Microsoft

One of the attractions of cloud computing is the financial saving gained through the elastic provision of compute services, that is, the ability to scale up and down the number of instances of a hosted service.

In this article by Neil Mackenzie, author of Microsoft Windows Azure Development Cookbook, we will see how the Windows Azure Service Management REST API can be used to autoscale a hosted service, so that it can handle the current and predicted load depending on the day of the week. By autoscale we mean the ability of a hosted service to scale itself elastically by modifying automatically the number of running instances.

Away3D 3.6: Applying Animated and Composite materials

by Matthew Casperson | March 2011 | Open Source Web Graphics & Video

In this article by Matthew Casperson, author of Away3D 3.6 Essentials we will explore Animated and Composite materials. A number of materials can be used to display animations on the surface of a 3D object. These animations are usually movies that have been encoded into a SWF file. You can also display an interactive SWF file, like a form, on the surface of a 3D object. Composite materials are used to display a number of effects like shading, bump mapping, environment mapping, and lighting. The reader will comprehend this article better by referring the previous articles on:

Away3D 3.6: Applying Light and Pixel Bender materials

by Matthew Casperson | March 2011 | Open Source Web Graphics & Video

Away3D includes a large selection of materials. There are various shading techniques that can be used by these materials, which allows for a selection of materials ranging from those that display a simple texture map to those more advanced materials, which produce more interesting detailed results like reflections, lighting, and shadowing.

In this article by Matthew Casperson, author of Away3D 3.6 Essentials, we will cover Pixel Bender, and seen how it has been used by Away3D to create some of these advanced materials. Those materials that can be lit from an external light source are listed, along with a table that breaks down the types of light sources that affect these materials. We will also see how resources, like textures, can be embedded into the final SWF, or loaded from external resources.

Away3D: Detecting Collisions

by Michael Ivanov | June 2011 | Open Source Web Graphics & Video

Three dimensions are better than two — and it's not a secret anymore that 3D is here to stay. Gone are the days when Flash was just used for 2D animations. In the last few years, online Flash content has undergone a revolution with the introduction of real-time 3D engines for Flash. Away3D is the big daddy of them all—which makes it the ultimate resource for top-rated 3D content development and for powering today's coolest games and Flash sites.

In this article by Michael Ivanov, author of Away3D 3.6 Cookbook, we will see how to detect collisions between objects in Away3D.
