Information Dashboard Design: The Effective Visual Communication of Data ReviewAfter reading this book I have the following positive points to make:
.. It is very well designed, it is nice to look at it.
.. Has some good ideas (but they are not original ones).
.. In general, following its advice you will be able to do a better design of dashboards and management information systems screens.
If I counted only this I would give it 5 stars, but, I think this book has some negative points. One of the points makes the author inconsistent with his own recommendations throughout the book.
The book is about designing dashboards and the major line of thought is:
- keep it simple, clean and objective.
- Use the tools (graphics and tables) in a rational way.
- don't use all the fancy features that software vendors put in their products for they will make your dashboard less effective.
But the author when writing it, forgot part of his own teachings and produced a text that is very prolixic, too many words to explain simple concepts and ideas. Lacks objectivity.
So, if you want to better understand the use of graphs, take a look at Naomi Robbins, "Creating More Effective Graphs". This book is very objective, simple and fast to read.

The second flaw is that in the examples to show how to do a well designed dashboard, the author used two types of graphs that are not available in today's softwares. One type of graph was created by the author while writing this book (bullet graphs) and the other (sparkline) is the creation of Mr.Tufte, which will appear in a future book of his. It would be more useful to see examples with the typical tools available to design a dashboard.So, be prepared for a nice experience with pictures and graphs in a sea of words. It is an excellent book that will help design dashboards and the like. (So far is the best book on this topic).
Information Dashboard Design: The Effective Visual Communication of Data OverviewDashboards have become popular in recent years as uniquely powerful tools for communicating important information at a glance. Although dashboards are potentially powerful, this potential is rarely realized. The greatest display technology in the world won't solve this if you fail to use effective visual design. And if a dashboard fails to tell you precisely what you need to know in an instant, you'll never use it, even if it's filled with cute gauges, meters, and traffic lights. Don't let your investment in dashboard technology go to waste.
This book will teach you the visual design skills you need to create dashboards that communicate clearly, rapidly, and compellingly. Information Dashboard Design will explain how to:

Avoid the thirteen mistakes common to dashboard design
Provide viewers with the information they need quickly and clearly
Apply what we now know about visual perception to the visual presentation of information
Minimize distractions, cliches, and unnecessary embellishments that create confusion
Organize business information to support meaning and usability
Create an aesthetically pleasing viewing experience
Maintain consistency of design to provide accurate interpretation
Optimize the power of dashboard technology by pairing it with visual effectiveness

Texas Instruments Voyage 200 Calculator ReviewThe actual calculator itself is stunningly powerful. It is faster than the TI-92, the full keyboard makes it easier to work with than the TI-89, and the ability to solve, factor, work with imaginary numbers, give exact answers, as well as do all of these things symbolically, plus the amazing applications included (a version of Geometer's sketchpad!), make this the best calculator made by TI.
Just beware that some standardized tests and some teachers will not let you use this calculator.
The biggest drawback is the documentation that is supposed to help you utilize the power of this calculator. There really isn't any. There's a short manual that's included in the box, but it only gives you the broad overview of how to put the batteries in and how to turn it on and off.
To find any information on how to, say, type something in that you want to factor, you have to load up the cd-rom, and hunt around on that thing to find the information you want.
Why don't they include all of this documentation along with the calculator in an actual book form? (Okay, so I know the answer to that - it saves money for them.)
It's a huge hassle - if I'm at class, or work and want to be able to use some function, I have to wait to figure it out until I can get home and load up the cd-rom, find the right page, etc....not to mention that the documentation on the CD-rom isn't that helpful either. There's lots of discussion of stuff, but it is very hard to understand.
A great calculator, but awful documentation that makes learning how to use all of its powerful functions frustrating and annoying.Texas Instruments Voyage 200 Calculator OverviewTexas Instruments 200 Calculator TIVOYAGE200 Calculators
