Coding for Journalists 101 : A four-part series Photo by Nico Cavallotto on Flickr Update, January 2012: Everything…yes, everything, is superseded by my free online book, The Bastards Book of Ruby, which is a much more complete walkthrough of basic programming principles with far more practical and up-to-date examples and projects than what you’ll find here. I’m only keeping this old walkthrough up as a historical reference. I’m sure the code is so ugly that I’m not going to even try re-reading it. 10 tools that can help data journalists do better work, be more efficient It’s hard to be equally good at all of the tasks that fall under data journalism. To make matters worse (or better, really), data journalists are discovering and applying new methods and tools all the time. As a beginning data journalist, you’ll want to develop a sense of the tools others are using to do the work you admire. You won’t be able to learn them all at once, and you shouldn’t try.

When using Fusion Tables with an unsupported browser, the Network Graph visualization will not be available.
The Best Data Mining Tools You Can Use for Free in Your Company Data mining or “Knowledge Discovery in Databases” is the process of discovering patterns in large data sets with artificial intelligence, machine learning, statistics, and database systems. The overall goal of a data mining process is to extract information from a data set and transform it into an understandable structure for further use. Here is a simple but fascinating example of how data mining helped dissipate wrong assumptions and conclusions about girls, and take action with tremendous social impact.
