In this article by Dinangkur Kundu and S. M. Ibrahim Lavlu, we will see how to add network-attached devices in the Cacti system and produce graphs to monitor LAN-sized installations to complex networks with hundreds of devices. It is fairly easy to manage devices through the Cacti web front-end. It provides a fast poller, advance graph templating, and multiple data acquisition methods out of the box, wrapped in an easy to use interface that makes sense to the network administrator.Read Using Graphs to Manage Networks and Devices with Cacti 0.8 in full
A good software developer always keeps the DRY principle in mind. Whenever code is duplicated, maintainability problems are introduced and the code base becomes difficult to understand. Java developers often rely on the template method pattern to reuse code. Groovy's closure programming concept is an alternative way to solve similar problems. Closures provide a concise way to pass around code without the ceremony involved with design patterns. This article by Nirav Assar will demonstrate how closures are used to embrace the DRY principle.Read Using Groovy Closures Instead of Template Method in full
So far, we have only used Hive through its interactive console. In this article by Darren Lee, author of Instant Apache Hive Essentials How-to [Instant], we will learn how Hive supports uses cases, such as periodic ETL jobs, by rerunning the top athletes query in batch mode from the command line. This support allows us to use external tools to start Hive jobs and capture their output.Read Using Hive non-interactively (Simple) in full

Indexes are not advanced because they're difficult, but if we want to be an expert with pandas it is important that we use them well. We will discuss hierarchical indexes in the following There's more... section.Read Using indexes to manipulate pandas objects in full
A Windows Azure hosted service may comprise multiple instances of multiple roles. These instances all run in a remote Windows Azure data center—typically 24*7. The ability to monitor these instances non-intrusively is essential both in detecting failure and in capacity planning.
However, there are times, especially early in the development process, when non-intrusive diagnostics monitoring is not sufficient. In this article by Neil Mackenzie, author of Microsoft Windows Azure Development Cookbook, we will see the benefits of intrusive monitoring of a Windows Azure role instance using IntelliTrace.Read Using IntelliTrace to Diagnose Problems with a Hosted Service in full
In this article by Karthik Kumar, author of the book Drupal 6 Theming Cookbook, we will be covering the following recipes:

Maps provide a great visual experience for location-based services. Maps are now a default feature on most smartphones as they provide a good graphical overview of information (usually geotagged data) around the user's location.
With custom pin markers and directions, maps also help users navigate to their destination easily. Most importantly maps give the user a feeling that "This place is around the next block, north from where I am standing," so decision-making happens quickly for the user.
In this article by Zeeshan Chawdhary, author of Windows Phone 7.5: Building Location-aware Applications we shall cover the following topics:
- Understanding map geometry
- Overview of Windows Bing Maps Silverlight Control
- Using maps in your Windows Phone application – Hello Maps
- Using pushpins with maps
- Custom map pushpins
- Handling pushpin events
- Working with Bing Maps geocoding and reverse geocoding services
