I am writing this text (Mar 12) to give you some peace of mind regarding some of the troubles in Japan, that is the safety of Japan’s nuclear reactors. Up front, the situation is serious, but under control. And this text is long! But you will know more about nuclear power plants after reading it than all journalists on this planet put together.

There was and will *not* be any significant release of radioactivity.

By “significant” I mean a level of radiation of more than what you would receive on – say – a long distance flight, or drinking a glass of beer that comes from certain areas with high levels of natural background radiation.

Today, as social media continues radically to transform how we communicate and interact, I can't help thinking with a heavy heart about The Woman in Blue. You see, in the networking age of Facebook, Twitter and Foursquare, the social invisibility that Vermeer so memorably captured is, to excuse the pun, disappearing. That's because, as every Silicon Valley notable, from Eric Schmidt to Mark Zuckerberg, has publicly acknowledged, privacy is dead: a casualty of the cult of the social. Everything and everyone on the internet is becoming collaborative. The future is, in a word, social.

The problem of isolation goes beyond ordinary loneliness, however. Consider what we’ve learned from hostages who have been held in solitary confinement—from the journalist Terry Anderson, for example, whose extraordinary memoir, “Den of Lions,” recounts his seven years as a hostage of Hezbollah in Lebanon.

He missed people terribly, especially his fiancée and his family. He was despondent and depressed. Then, with time, he began to feel something more. He felt himself disintegrating. It was as if his brain were grinding down. A month into his confinement, he recalled in his memoir, “The mind is a blank. Jesus, I always thought I was smart. Where are all the things I learned, the books I read, the poems I memorized? There’s nothing there, just a formless, gray-black misery. My mind’s gone dead. God, help me.”

Shouldn’t we struggle against Facebook? Everything in it is reduced to the size of its founder. Blue, because it turns out Zuckerberg is red-green color-blind. “Blue is the richest color for me—I can see all of blue.” Poking, because that’s what shy boys do to girls they are scared to talk to. Preoccupied with personal trivia, because Mark Zuckerberg thinks the exchange of personal trivia is what “friendship” is.

...

I can’t imagine life without files but I can just about imagine a time when Facebook will seem as comically obsolete as LiveJournal. In this sense, _The Social Network_ is not a cruel portrait of any particular real-world person called “Mark Zuckerberg.” It’s a cruel portrait of us: 500 million sentient people entrapped in the recent careless thoughts of a Harvard sophomore.

A great deal of money is at stake. Cyber security is a major growth industry, and warnings from Clarke, McConnell, and others have helped to create what has become a military-cyber complex.

American intelligence and security officials for the most part agree that the Chinese military, or, for that matter, an independent hacker, is theoretically capable of creating a degree of chaos inside America. But I was told by military, technical, and intelligence experts that these fears have been exaggerated, and are based on a fundamental confusion between cyber espionage and cyber war. Cyber espionage is the science of covertly capturing e-mail traffic, text messages, other electronic communications, and corporate data for the purpose of gathering national-security or commercial intelligence. Cyber war involves the penetration of foreign networks for the purpose of disrupting or dismantling those networks, and making them inoperable.

Throughout recorded history most people who have wanted a household article have bought or bartered it from someone else – in past times an artisan or trader, more recently a seller of mass-produced products. With few exceptions (such as some clothing) it is rare that any of us make such articles for ourselves these days. That may soon change.

In the first part of this paper, we review the history of 3D printing and describe recent developments, including a project initiated by one of the authors to bring such printers into the home. We then examine the IP implications of personal 3D printing with particular reference to the bundle of rights that would typically be associated with a product that might be copied.

Our most powerful 21st-century technologies - robotics, genetic engineering, and nanotech - are threatening to make humans an endangered species.
