7 stories to read this weekend

For some odd reason, I have not been able to add a diverse enough reading materials to the mix this week and as a result, there is an unusually large number of tech-centric stories on my recommendation list. Here are the picks for this weekend.

• Hunger Games: How iPhones make anorexia worse. Apps are sort of to blame, argues New Republic writer Alice Gregory.
• How photographing events stops us from living them: Jillian Edelstein of The Guardian makes a fair argument about this behavior.
• Bitcoin, magical thinking and political ideology: Alex Payne bursts the Bitcoin bubble with a well-reasoned argument.
• Bunches of guys: Owen Bennet-Jones talks about the resurgence of al-Qaida in the London Review of books.
• The math equation that explains David and Goliath. Everything is math, in case you were wondering.
• There’s a 1,200 year old Phone in the Smithsonian collections. And it is pretty damn awesome and very simple.
• Tech and the city: Nancy Scola asks the tough questions about New York and its desire to jumpstart an innovation economy. One of the best pieces I have read in a long time, even if it is more than a year old.
