The Relationship Between Facebook and Privacy: It's Really Complicated: Tech News « The tension between Facebook and its users — and governments, and advocacy groups — over privacy is one of the biggest thorns in the company’s side right now, as it tries to balance the demands of the network (and of advertisers) with the desires of users, and with the law. And all of this is taking place in an environment where the very meaning of what is “private” and what is “public” is being redefined, by Facebook and other online giants such as Google, and even users themselves sometimes can’t decide what information they want to share with the world and what they don’t. Over the past few weeks, the social network has been caught at the center of a privacy maelstrom, with consumer groups attacking it — 15 of them filed a formal letter of complaint with the Federal Trade Commission late yesterday — senators sending threatening letters, and growing numbers of users canceling or deactivating their accounts over privacy concerns. And privacy?

Majestic shuttle in unique station image By Jonathan Amos Science correspondent, BBC News It is a stunning image and one that is bound to be reproduced over and over again whenever they recall the history of the US space shuttle. The picture was taken by Italian astronaut Paolo Nespoli as he left the International Space Station in May in a Soyuz capsule to return to Earth.

Internet censorship Internet censorship is the control or suppression of what can be accessed, published, or viewed on the Internet. It may be carried out by governments or by private organizations at the behest of government, regulators, or on their own initiative. Individuals and organizations may engage in self-censorship for moral, religious, or business reasons, to conform to societal norms, due to intimidation, or out of fear of legal or other consequences.[1] The extent of Internet censorship varies on a country-to-country basis. While most democratic countries have moderate Internet censorship, other countries go as far as to limit the access of information such as news and suppress discussion among citizens.[1] Internet censorship also occurs in response to or in anticipation of events such as elections, protests, and riots. An example is the increased censorship due to the events of the Arab Spring.

RepRapWiki TEDxEWB Talk: Adrian Bowyer at Imperial College, London, introduces RepRap RepRap is humanity's first general-purpose self-replicating manufacturing machine. RepRap takes the form of a free desktop 3D printer capable of printing plastic objects. Since many parts of RepRap are made from plastic and RepRap prints those parts, RepRap self-replicates by making a kit of itself - a kit that anyone can assemble given time and materials. Our data is our digital identity - and we need to reclaim control I’m a film-maker by trade, so heading to Capitol Hill the other week was a new experience for me. I was there to talk privacy, and in essence, to advocate. I didn’t have the first clue where to begin. The architecture, both impressive and oppressive, made me feel simultaneously important and meagre, and as I was later told, this was intentional. For the past month we have accrued about 20,000 signatures at our site trackoff.us, from people who want their Congressmen to see my film about digital privacy: Terms and Conditions May Apply. I had a feeling a lot of people on the Hill didn’t really understand how privacy has been eroded through the digital corporate/government alliance.
