Disaster Recovery Techniques for End Users

by Jeff Gellman Joel Plaut Pat Esposito Pavlo Andrushkiw Peter Abreu Peter Ward | October 2013 | Enterprise Articles

In this article by Peter Ward, Peter Abreu, Pavlo Andrushkiw, Pat Esposito, Jeff Gellman, and Joel Plaut, the authors of Microssoft SharePoint 2013 Diaster Recovery Guide, explains data prevention and recovery procedures that should be applied by users with their SharePoint collaboration activities to prevent data loss.

The reader of this article is probably technical, and therefore perhaps a little surprised by the title and the topic of this article. You probably assume that DR is an IT department activity, so why should the end user even think about it?

Choosing the right flavor of Debian (Simple)

by Jose Miguel Parrella | October 2013 | Networking & Telephony Open Source

In this article written by Jose Miguel Parrella, the author of the book Instant Debian – Build a Web Server explains how Debian organizes software, the architectures, and installation methods, and indicates a set of criteria for system administrators to choose and get the right media.

The Debian Project prides itself on producing the Universal Operating System. This means that the software the project puts together runs on a broad set of hardware (architectures) for several types of purposes, and even for different kernels such as Linux, Hurd, or FreeBSD.

Choosing the right flavor of Debian for your setup might seem intimidating at first, but this recipe will provide you with decision elements to help you reduce your time to market with Debian and choose the right architecture and installation method, particularly for a web server.

Minimizing HTTP requests

by Sanjeev Jaiswal | October 2013 | Open Source

The website can be made faster in many ways, one of them being reducing requests sent to the server, which will ultimately minimize the delay. The fewer the server requests, the faster the website will be.

We can do it in various ways but in this article by Sanjeev Jaiswal, author of Instant PageSpeed Optimization, let's concentrate on more important ones

So, what is XenMobile?

by Aamir Lakhani | October 2013 | Open Source

In this article, by Aamir Lakhani, the author of Instant XenMobile MDM discusses about XenMobile in brief. Reports from the Internet estimate that there will be an explosion of mobile devices in corporate businesses. Mobile devices are quickly becoming the computing device of choice. Unlike traditional computing devices, mobile devices are designed for consumers before businesses, and therefore organizations are having a difficult time securing and managing these devices. They have turned to mobile device management solutions to help them manage both corporate and BYOD devices in a secure manner within their organization.

Customizing a Linux kernel

by Daniel Manchón Vizuete | October 2013 | Open Source

In this article by Daniel Manchón Vizuete, author of Instant Buildroot, we will learn how to customize a Linux kernel using Buildroot. This article is a must-read for users new to embedded software design, but who already have some experience with software development and Linux.

The Linux kernel is a huge project, and it's full of configuration options and device drivers. Usually, we need to tune the kernel in order to add some basic functionality, integrate the drivers of our devices, or reduce the total size disabling the unused functions and drivers. In this article, we will walk through the most common kernel configuration options.

Gamified Websites: The Framework

by Detrick DeBurr | October 2013 | Open Source Web Development

In this article by Detrick DeBurr, the author of Build Gamified Websites with PHP and jQuery, we will follow a Gamification Design Framework, which is made up of six components. They are:

  • Business objectives
  • Target behaviors
  • Players
  • Activity loops
  • Fun
  • Tools

Over the next few pages, we will take a closer look at each and begin to put "meat" on the "bones" of our gamified e-learning website.

We will wrap up this article with a mock-up of what our final product will look like at a high level. This will make getting in the details and building our application considerably easier.

Dependency Management in SBT

by Shiti Saxena | October 2013 | Open Source Web Development

Software development never happens in isolation. Most of the time, for complex projects, you will not work alone, nor will you develop all the components in the product from scratch. Products are generally created in teams, and they generally rely on external libraries and components. A product itself can be broken into modules developed by different teams dependent on each other. Dependencies in software development refer to the libraries or components required at various stages (compile, test, and runtime) of an application's development life cycle. The process of handling these dependencies, external or internal, for your application is called dependency management. In this article by Shiti Saxena, author of Getting Started with SBT for Scala, we will venture into dependency management.

On the surface, it looks simple. All you have to do is take the JAR file and add it to your project. But when you actually have to handle it, problems arise. Some of the challenges are as follows:

  • Version management: This will track the version of various dependencies you are using. Download the latest ones when they become available and replace the old ones. Ensure someone else in the team doesn't simply change the JAR file to a newer/older version.
  • Transitive dependencies: This handles the chain of dependencies of the libraries you are dependent on, and also the dependencies of these dependencies.
  • Releasing your library: If your library is part of a larger project, making your library available to others to use in an easy way is a challenge, especially when it is updated frequently (think about nightly snapshots).
