Find Orphan Song Titles in iTunes

In the last blog post, you learned to read songs from an exported iTunes XML file. If you have been using iTunes for a long time and have deleted songs, merged songs from other libraries, or moved your library from one computer to another, then you may not know it, but there could be song files on your hard drive that are no longer in your iTunes library. This blog post shows you how to locate those missing files. To follow along with this blog post, read and follow the instructions in the first blog post on reading songs from iTunes.

Doing Work Right - Part 2: Projects

In an earlier blog article, I discussed why you need a solid demand management process. Demand is what others are asking you to do. It is your “to-do” list or backlog of activities. From this list or backlog, you must be able to select the right work. The other part of what you do for a living is executing the work: doing work right. Therefore, “right work” (what is best to do next) vs. “work right” (what people, processes, or tools will be employed to do the work in the most effective way).

iTunes Player Part 1: Read Songs From iTunes

Have you ever wanted to retrieve the list of songs from your iTunes library? Getting songs from iTunes is not easy. In fact, since Apple stopped supplying their COM component for reading from their iTunes library, about the only way to get song data is to export the library into an XML file, then parse the XML. In this blog post, you are going to learn to parse the XML using the classes contained in the System.Xml.Linq namespace.

A Message Broker for XAML Applications

In any application, you want to keep the coupling between any two or more objects as loose as possible. Coupling happens when one class contains a property that is used in another class or uses another class in one of its methods. If you have this situation, then this is called strong or tight coupling. One popular design pattern to help with keeping objects loosely coupled is called the mediator design pattern. The basics of this pattern are very simple; avoid one object directly talking to another object, and instead use another class to mediate between the two. This class is called a message broker. The purpose of this blog post is show you a simple approach to using a message broker in your XAML applications.

Business Intelligence: You Need a Date Dimension (Power BI)

I challenge you. I challenge you to think of a report that doesn’t rely on a date somewhere in it.  Thought of one? If you did, is the information in the report actually valuable without some type of date range boundary? Even in academia and clinical research, where groundbreaking reports are published and stand up to scrutiny for decades, researchers still clearly call out the dates in which the data was collected. They do this because they know the results of their experiments were valid for the date and time they were collected, but could still change at any time. Remember: it was a scientifically held belief that the Earth was the center of the universe for a long time.
