No Date? No Time!

I’ve not been working on Windows much lately, but while installing Windows XP today, I was greeted with this fine work of nonfiction, which reminds me why I miss it so:

oh, well i guess that makes sense

So I can’t synchronize the time because…the time on the machine is incorrect. And not only that, but my state represents a security risk to the time synchronization machine in the sky.

I hope the person who wrote this error message enjoyed it as much as I did. At least when writing bad error messages in Processing I have some leeway for making fun of the situation (hence the unprofessional window titles of some of the error dialogs).

Book

Visualizing Data Book CoverVisualizing Data is my book about computational information design. It covers the path from raw data to how we understand it, detailing how to begin with a set of numbers and produce images or software that lets you view and interact with information. Unlike nearly all books in this field, it is a hands-on guide intended for people who want to learn how to actually build a data visualization.

The text was published by O’Reilly in December 2007 and can be found at Amazon and elsewhere. Amazon also has an edition for the Kindle, for people who aren’t into the dead tree thing. (Proceeds from Amazon links found on this page are used to pay my web hosting bill.)

Examples for the book can be found here.

The book covers ideas found in my Ph.D. dissertation, which is basis for Chapter 1. The next chapter is an extremely brief introduction to Processing, which is used for the examples. Next is (chapter 3) is a simple mapping project to place data points on a map of the United States. Of course, the idea is not that lots of people want to visualize data for each of 50 states. Instead, it’s a jumping off point for learning how to lay out data spatially.

The chapters that follow cover six more projects, such as salary vs. performance (Chapter 5), zipdecode (Chapter 6), followed by more advanced topics dealing with trees, treemaps, hierarchies, and recursion (Chapter 7), plus graphs and networks (Chapter 8).
