November 22 2013Let’s examine the followers of some popular Twitter users by asking the (Freakonomics-inspired) question, What do Tim O’Reilly, Lady Gaga, and Marissa Mayer all have in common? Although it may initially seem like an obnoxious question to ask, some of the answers may … read more
November 12 2013We can now gather from Twitter’s IPO that it’s fundamentally postured as an advertising company, but its real value isn’t in advertising. Twitter’s most fundamental value rests squarely within data analytics. However, just because Twitter could make a lot of money in … read more
October 14 2013Tomorrow, I’ll be presenting a short webcast entitled Why Twitter Is All the Rage: A Data Miner’s Perspective that is loosely adapted from material that appears early in Mining the Social Web (2nd Ed). Given that the webcast is almost here, I wanted … read more

September 21 2010Creating financial software for the developing world is tricky business. Variations between countries -- and between the banks within those countries -- make proprietary solutions unsustainable without massive investment.

Webcast: Data Science Experiments with Twitter and IPython Notebook
Webcast: Why Twitter Is All the Rage: A Data Miner's Perspective
"A worthy upgrade to the first edition, this time not PHP but enumerated in Python. Does a good job of plotting & describing PayPal's increasingly byzantine "workflows" to bop payments back and forth."
"If you are trying to figure out where you or your business fits into Twitter, Mining Twitter is a must have book for you! "
"Its a slam dunk for Python programmers.
"It is an incredible companion to get you moving in pulling data, trends or just about anything from Twitter."
"Invaluable custom apps, or at least a good solid start in doing so."
"I got out of my comfort zone and learned several things from this book, so I recommend it to all readers who need to improve their understanding of data."
"This fast-paced and rich handbook jumps right into the fray and provides an immediate and useful exercise in accessing the Twitter API using python and doing a very quick visualization of trending subjects. I was hooked and greedily and immediately consumed a few more of his lessons. "
"Kudos to the organization of the book, with chapter 'encapsulation', allowing for each chapter to be read independently, for each social web network. The e-book is enjoyable because it has a lot of hyperlinks, which is quite convenient..."
"Readers often expect an advanced level of technical description and thoroughness from OReilly, and Dojo: The Definitive Guide meets this description."
"Any computer library strong in web development will find Dojo: The Definitive Guide an excellent introduction which covers all 1.x versions and offers plenty of examples and tested code sets. From customizing Dojo to overseeing developers using Dojo in larger settings, this offers the programmer/manager a set of keys to working efficiently with Dojo to produce superior layouts and web applications."
"Not only has Matthew done an outstanding job documenting and explaining the Dojo Toolkit in great and understandable detail in this book, he's made the Dojo toolkit better through his authoring process by asking hard questions when things did not work the way they should. His suggestions have improved Dojo, and this book lives up to its billing as the Definitive Guide for Dojo."
