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.Read Automation with Python and STAF/STAX in full
Spring allows us to use "autoproxy" bean definitions, which can automatically proxy selected bean definitions. There are three kind of autoproxies provided for automatic creation of beans. In this article by Massimiliano Dessi, we will look at this in detail.Read Autoproxy in Spring Aspect-Oriented Programming (AOP) in full
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.Read Autoscaling with the Windows Azure Service Management REST API in full

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:
- Materials, Lights and Shading Techniques with Away3D 3.6.
- Away3D 3.6: Applying Basic and Bitmap Materials.
- Models and Animations with Away3D 3.6.
Away3D includes over a dozen material types that can be used to display 3D objects with a huge variety of effects, with some of the materials using the Pixel Bender technology new to Flash Player 10 to create a level of detail that has not previously been seen in Flash applications.
In the previous article by Matthew Casperson, author of Away3D 3.6 Essentials, we covered Materials, Lights and Shading Techniques with Away3D 3.6. In this article the focus will be on:
- The different materials that can be created in Away3D
- Illuminating materials with lights
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.Read Away3D 3.6: Applying Light and Pixel Bender materials in full
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.Read Away3D: Detecting Collisions in full
This article covers some advanced topics such as conditions, raised events, and so on.
In this article by Ezra Schwartz, author of Axure RP 6 Prototyping Essentials, we will cover a set of features such as raised events, conditional logic and variables, introduction to a terminology which is usually associated with programming and suggests complexity. It is understandable if you are not interested in, or are intimidated by, the prospect of coding, and wish to avoid using this set of Axure features as long as possible. You should not.
First, rest assured that no coding is involved. By now, you are familiar with Axure's Interactions and the Case Editor features, which require you only to select from a contextual selection of options and construct interactions by pointing and clicking. The only typing required is the labeling. You will find a similar easy-to-use interface when you use features such as the Condition Builder or simulate "drag and drop".
Secondly, think about some of the terminologies and methods we use in interaction design. We use branching logic to determine use cases, scenarios, and how functionality responds to user interaction under certain conditions. Axure makes it fairly easy to model the logic we need, in order to visualize branching paths, and express it in the interactive prototype.Read Axure RP 6 Prototyping Essentials: Advanced Interactions in full

All web applications and web servers have security vulnerabilities and there is every chance that our website will be compromised. Most web hosts have their own backup procedures in place, but it is not uncommon for a web host to become victim to an attack, and have problems with a small percentage of its customer backups. Because of this it is very important that we keep backups of our website. In this article by Michael Peacock, we will see how to backup our website and restore it back gain from our backup.Read Backing Up and Restoring TYPO3 Websites in full
Penetration Testing, sometimes abbreviated as PenTest, is a process that is followed to conduct a hardcore security assessment or audit. A methodology defines a set of rules, practices, procedures, and methods that are pursued and implemented during the course of any information security audit program with the BackTrack operating system environment. The key topics covered in this article by Shakeel Ali and Tedi Heriyanto, authors of BackTrack 4: Assuring Security by Penetration Testing, include:
- Discussion on two well-known types of penetration testing, Black-Box and White-Box
- Exhibiting clear differences between vulnerability assessment and penetration testing
- Explaining the industry acceptable security testing methodologies with their core functions, features, and benefits
- The BackTrack testing methodology incorporating the ten consecutive steps of penetration testing process
- The ethical dimension of how the security testing projects should be handled
This article by Shakeel Ali and Tedi Heriyanto, authors of BackTrack 4: Assuring Security by Penetration Testing, covers a scope process to provide necessary guidelines on formalizing the test requirements. A scope process will introduce and describe each factor that builds a practical roadmap towards test execution. This process integrates several key elements, such as gathering client requirements, preparing a test plan, profiling test boundaries, defining business objectives, and project management and scheduling. You will learn to acquire and manage the information about the target's test environment.Read BackTrack 4: Target Scoping in full
Wireless Networks have become ubiquitous in today's world. Millions of people use them worldwide every day at their homes, offices, and public hotspots to log on to the Internet and do both personal and professional work.
In this article by Vivek Ramachandran, author of BackTrack 5 Wireless Penetration Testing Beginner’s Guide, we will look at how we can conduct advanced attacks. We will primarily focus on Man-in-the-Middle (MITM) attack, which requires a certain amount of skill and practice to conduct successfully. Once we have done this, we will use this MITM attack as a base to conduct more sophisticated attacks such as Eavesdropping and Session Hijacking.
We will cover the following:
- Man-in-the-Middle attack
- Wireless Eavesdropping using MITM
- Session Hijacking using MITM
In this article by Vivek Ramachandran, author of BackTrack 5 Wireless Penetration Testing Beginner’s Guide, we will focus on attacking the client. Most people exclude the client from their list when they think about WLAN security. This article will prove beyond doubt why the client is just as important as the access point when penetrating testing a WLAN network. The client can be either a connected or isolated un-associated client. We will look at various attacks, which can be used to target the client.
We will cover the following:
- Honeypot and Mis-Association attacks
- Caffe Latte attack
- De-Authenticaton and Dis-Association attacks
- Hirte attack
- AP-less WPA-Personal cracking
Computer forensics involves using various means to analyze, report, and recover information from computers or digital storage media, generally for legal purposes. The outcome in general is to provide the information gathered in such a way that it is useful for the person requesting the information. This includes the recovery of passwords, analyzing computer break-ins or attempts, recovering data from a hard drive after it's been "erased", and so on. In the article by Willie Pritchett and David De Smet authors of BackTrack 5 Cookbook we will examine how BackTrack can be utilized for forensic purposes.
In this article, we will cover:
Intrusion detection and log analysis
Recursive directory encryption/decryption
Scanning for signs of rootkits
Recovering data from a problematic source
Retrieving a Windows password
Resetting a Windows password
Looking at the Windows registry entries
The lines between on-premise and public cloud services have become blurred. The integration between on-premise and off-premise technologies imply that you can now easily implement a backup solution that makes use of both, thus allowing you to maintain up-to-date backups both on-site and off-site. This will allow you to implement a disaster recovery plan that meets strict service-level agreements without having to invest in a Disaster Recovery (DR) site. The DR site can be in the cloud. Depending on your environment, this can significantly reduce the cost of implementing a fully blown disaster recovery site or server room.
There are several new features in SQL Server 2014 that make this possible; they are as follows:
