Drilling Back to Source Data in Dynamics GP 2013 using Dashboards

In this article by Mark Polino, author of Building Dashboards with Microsoft Dynamics GP 2013 and Excel 2013, will walk you through the deployment of a dashboard. Once you deploy a dashboard, it's inevitable that someone will want more information. They won't believe a number and will want to know the detail that makes up a balance. A great way to manage this is to build a couple of dashboards. Usually, this looks like a primary dashboard with secondary dashboards that break out more information about sales, cash, or departments. We've done this on a very simple level with our Revenue and Net Income tabs. They provide additional detail to expand on the main dashboard numbers.

Another great way to deal with the need for detail, and to take your dashboard beyond what everyone else is doing, is to allow users to drill down into specific transactions or accounts in Microsoft Dynamics GP 2013. In this article, we will look at drill down options including:

• Hyperlinks

• Using drill downs present in GP 2013

• The structure of a drill down

• Building your own links with Drill Down Builder

• Drill downs in complex environments

Insight into Hyper-V Storage

In this article by Zahir Hussain Shah, the author of Windows Server 2012 Hyper-V: Deploying Hyper-V Enterprise Server Virtualization Platform, we will dive deeper into Hyper-V storage, where we will discuss the various types of storage options available with Microsoft Windows Server 2012 Hyper-V for a virtual machine in detail.

Tracking Faces with Haar Cascades

This article by Joseph Howse, author of OpenCV Computer Vision with Python introduces some of OpenCV's tracking functionality, along with the data files that define particular types of trackable objects. Specifically, we look at Haar cascade classifiers, which analyze contrast between adjacent image regions to determine whether or not a given image or subimage matches a known type. We consider how to combine multiple Haar cascade classifiers in a hierarchy, such that one classifier identifies a parent region (for our purposes, a face) and other classifiers identify child regions (eyes, nose, and mouth).

We also take a detour into the humble but important subject of rectangles. By drawing, copying, and resizing rectangular image regions, we can perform simple manipulations on image regions that we are tracking.

By the end of this article, we will integrate face tracking and rectangle manipulations into Cameo. Finally, we'll have some face-to-face interaction!

Move Further with NumPy Modules

NumPy has a number of modules that have been inherited from its predecessor, Numeric. Some of these packages have a SciPy counterpart, which may have fuller functionality. The numpy.dual package contains functions that are defined both in NumPy and SciPy. The packages discussed in this article are also part of the numpy.dual package.

In this article by Ivan Idris from the book NumPy Beginner’s Guide - Second Edition, we shall cover the following topics:

• The linalg package
• The fft package
• Random numbers
• Continuous and discrete distributions
