Modern Systems Analysis and Design by Jeffrey A. HofferI read this book as it was the required textbook for a systems design class that I took, and I have very mixed feelings about it. On one hand, I think that it presents material in a good, progressive fashion. The material is real-world, it has three tangible example companies that provide for ample case studies in each chapter, and it is clearly illustrated and diagrammed.
I have two major qualms with the book, however, and one qualm with the material that accompanies it.
- First, the index was very disappointing. Part of my course was a 50-page systems design report, and much of the material I needed to discuss was from the textbook. Over half of the time, the term that I needed to look up (such as test case or test scenario, neither of which are esoteric terms) was not in the index. Several times, I found a word in the glossary and not the index, and in general it was difficult to figure out where material was. That wouldnt be such an issue if it werent for point 2:
- Second, it was not intuitively organized. The organization wasnt horrible, but even after reading and studying the textbook, I still have difficulty finding things. Material was presented in a somewhat progressive format, and it wasnt very repetitive. While this is good in theory, that means that chapters 1-3 as well as 4-5 covered project planning topics. If something (such as how to draw a sequence diagram or how to calculate Return on Investment) is discussed, it will only be discussed briefly again. When the terms arent found in the index, it makes it very difficult to find specific information.
- Last, I was very frustrated with the test bank that seemed to accompany the book. While this isnt a qualm with the book itself, and Im not 100% positive it wasnt altered by the program, when googling unknown terms in practice tests, I was finding exact results, which means my professor wasnt the only one using those questions. The questions that were on the test were often very specific and nit-picky. This wasnt always a problem, but in several chapters, two or more terms may have had definitions that were vague or could potentially describe another term (since we were discussing different schools of thought in systems design, there were many equivalent concepts with different names). This led to some frustrating, ambiguous questions on tests and quizzes.
In short, the material presented in this book is great, but I spent far too much time frustratedly flipping through the book trying to find particular sentences to rate it higher than two stars. If you need this book for a class, you may want to try an ebook.

Customize Drop In
Amazon Echo Show is a smart speaker that is part of the Amazon Echo line of products., When the Amazon Echo Show launched last June, it became the first Alexa speaker to feature a screen - but it wasn't the best looking, nor did it offer the friendliest integrations.
Amazon's voice assistant, Alexa, is infiltrating your home, your beach trips and even your ride to work. The list of commands is expanding rapidly, as is the number of third-party services and devices that Alexa officially and unofficially supports. By default, Amazon's connected speakers have the same wake word. All you have to do to queue up a request is say, "Alexa. Amazon updated the Tap with a hands-free mode that you must enable in the settings. The only wake word available to the Amazon Tap is Alexa. Earlier this year, Amazon added a feature called Follow-Up Mode that makes it easier and faster to issue multiple commands to Alexa without having to keep repeating the wake word.
For better or legitimately worse, the virtual assistant living in the Google Nest Hub now knows me. My favorite photos automatically show up on its 7-inch display. When I set an alarm, it knows to go completely dark afterwards so I can sleep. But it works well in an office, in the living room, on a kitchen countertop. And the Echo Show 5 seems slightly less vulnerable to the privacy foibles of earlier Alexa products. Oh right, Alexa!
