I know it's Fall in New York because the weather is changing and I wish I were back in Northern California where it never does. But inside, sheltered from the wind, I present you these links from the past week:

• With the rise of small-scale production and 3D printing, small goups of consumers can create their own dream tools. Like this Lucky Charms marshmallow sifter.
   
• What did Twitter know and when did it know it? How US intelligence agencies are using the social networking apparatus to predict the future.
   
• Among the things that can make you sick this week: economic inequality and mortgages.
   
• This is not a vacant lot.
   
• Silicon Valley has become a new locus for civil rights concerns (see the above link), so the Electronic Frontiers Foundation has a guide to San Francisco's Rightscon.
   
• Hacker collective Anonymous is up to its old tricks, now going after the nation's law enforcement officers in solidarity with Occupy Wall Street.
   
• An American cycling in Paris: one writer's ode to bike sharing in the city of lights.
   
• Even the rich are getting in on P2P car sharing, as it comes to Los Angeles.
