6-axis 3D printer can print on irregular surfaces
Yong Chen and his team at USC Engineering have built a six-axis-of-freedom 3D printer that can rotate its build platform and heads to enable it to print on irregular, curved and slanted surfaces; shown here, a 3D print on a curved bottle.
Associate Professor of Industrial and Systems Engineering Yong Chen of the University of Southern California has been experimenting with different mechanical arrangements for 3D extrusion printing...
The six axes operate similar to a delta unit, but offer the ability to tilt the extruder. This means, for example, this device can print on a slanted surface as the image above shows. Even more amazing is its ability to print on a curved surface, as seen here in the example of a print pasted onto a glass bottle.

Usuários usam fotos de Eric Schmidt no Google+ para protestar contra os novos termos de uso do Google
Era de se esperar que protestos contra os novos termos de uso do Google (ToS, na sigla em inglês) anunciados na semana passada não demorassem a aparecer. A surpresa é que alguns usuários encontraram uma forma “engraçadinha” de fazer isso: trocaram a imagem de seu perfil no Google+ por uma foto de Eric Schmidt, o chairman da companhia.
Os novos termos dão permissão ao Google de utilizar nome, foto e algum comentário do usuário em anúncios a serem exibidos somente para os seus contatos. A ideia é fazer com que estas informações sejam usadas para aumentar o interesse pelos anúncios: um banner tende a se tornar mais interessante para uma pessoa se o produto anunciado contiver a avaliação de um conhecido.
Exemplo de anúncios com dados de usuários
A intenção do protesto é quebrar, mais de maneira provocativa do que prática, a eficiência desta ideia: em vez de visualizar a foto de um amigo em um anúncio que tira proveito desta funcionalidade, a pessoa verá a cara de Eric Schmidt. Dá para encontrar a maioria dos perfis que aderiram ao protesto procurando pela tag #EricSchmidt no Google+.
Apesar do teor sarcástico dos protestos ou da possibilidade destes, na verdade, chamarem atenção para o tratamento que o Google dá para questões de privacidade como um todo, é importante ressaltar que os usuários não são obrigados a concordar com os novos termos.
Quem quiser garantir que suas informações não sejam usadas em anúncios deve acessar esta página do Google+, desmarcar a opção “Com base em minhas atividades, o Google poderá exibir meu nome e minha foto de perfil em recomendações compartilhadas em anúncios” e clicar em “Salvar”.

Cuba: A DIY Society?
After the U.S. left Cuba back in the 60′s, most of the engineers went with them, so [Fidel Castro] told the citizens to learn how to make stuff themselves. They were called the National Association of Innovators and Rationalizers (ANIR), and that’s exactly what they did. This was the beginning of Cuba’s backyard innovation.
Fastforward a few decades and the 90′s were a very difficult time for Cuba. With the collapse of the Soviet Union in 1991, a severe economic downturn almost crippled the country, and as a result a Cuban DIY culture began to flourish even more — out of absolute necessity. No money, no imports, only what they already had. Making and fixing things became a part of life, you couldn’t just go out and buy a solution to your problem, you had to do it yourself. This might be one of the greatest examples of what a full-flung maker/DIY society would be like — well, maybe minus the communist part.
The excellent video after the break is a short story about the designer [Ernesto Oroza], who started collecting examples of this DIY culture under his art project aptly called, Technological Disobedience. It’s worth the watch, so take a look.

You Have To Play With This Interactive Map Of The Galaxy
Thanks to the amazing powers of the internet (and super-creative developers), you can now travel through interstellar space without any fear of ending up like Sandra Bullock in Gravity. Click over to the 100,000 Stars interactive map of the galaxy, and fly through space from the safety of your own bedroom!
Built by Michael Chang and the Data Arts Team at Google, 100,000 Stars is an “interactive visualization of the stellar neighborhood,” which basically means you can mess around in space and feel like you’re really there. Showing the location of 119,617 nearby stars, you can zoom right in, from the whole Milky Way, to our local star system, and solar system. Clicking on a star will give you more info about it, and there’s also a really interesting interactive tour to get you started.
Oh, and did we mention the map is set to music composed by the same guy who did the music for Mass Effect?
This awesome map is part of the Chrome Experiments project, a showcase of web experiments that anyone can submit to the Google team. They’re all built in HTML5 and JavaScript using open web technologies like Canvas and WebRTC, and they are usually really, really cool. You can read a whole complicated description of how Chang and the team built the map right here.
They do warn you that the map might not be accurate to the mile, so please, don’t use it for interstellar travel.

Veja o crescimento do Facebook rumo ao domínio do mundo
O crescimento do Facebook nos últimos anos é surpreendente: a rede social de Zuckerberg já tem mais de 1,2 bilhão de usuários e é a mais popular em ao menos 127 países pelo mundo. É muita coisa.
Ao voltar alguns anos no passado percebemos quão rápida e surpreendente é a ascensão do Facebook. E é isso o que o Vincos ajuda a perceber, com o mapa mundial das redes sociais. Em 2009, não havia um nome tão forte como o Facebook: a rede social dominante variava mais de país para país. Mas em 2013 não – o Facebook está em todos os lugares. Nas Américas, em parte da África, na Europa Ocidental, em parte da Ásia.
Muita coisa aconteceu nesses quatro anos. No Brasil, podemos lembrar do momento em que o Orkut deixou o trono de rede social mais popular do país para o Facebook. Foi em 2011 e, depois disso, o cenário das redes sociais no Brasil ficou bem estranho.
Até onde o Facebook pode chegar? Será que em alguns anos veremos um mapa desses todo azul, ou o império de Mark Zuckerberg vai acabar em algum momento? [Vincos Blog via Digg]

How alien conspiracists are just like creationists
According to the popular series Ancient Aliens, on H2 (a spinoff of the History channel), extraterrestrial intelligences visited Earth in the distant past, as evidenced by numerous archaeological artifacts whose scientific explanations prove unsatisfactory for alien enthusiasts. The series is the latest in a genre launched in 1968 by Erich von Däniken, whose book Chariots of the Gods? became an international best seller. It spawned several sequels, including Gods from Outer Space, The Gods Were Astronauts and, just in time for the December 21, 2012, doomsday palooza, Twilight of the Gods: The Mayan Calendar and the Return of the Extraterrestrials (the ones who failed to materialize).
Ancient aliens theory is grounded in a logical fallacy called argumentum ad ignorantiam, or “argument from ignorance.” The illogical reasoning goes like this: if there is no satisfactory terrestrial explanation for, say, the Nazca lines of Peru, the Easter Island statues or the Egyptian pyramids, then the theory that they were built by aliens from outer space must be true.
119. JOHN GREEN: Make gifts for people
John Green (1977-) is an American author and video-blogger extraordinaire. He has written best-selling young adult novels including Looking For Alaska, Paper Towns and the recent The Fault in our Stars, which was named Time magazine’s best fiction book of 2012.
John and his brother, Hank, are the Vlogbrothers. They helped pioneer video blogging when they communicated only through YouTube videos for a year. They’ve since produced a wide variety of video series and have attracted a devoted army of fans known as the Nerdfighters.
I discovered John Green when a reader sent me the link to the awesome Crash Course World History series, which Green hosts and co-writes. The series tells the entire history of civilisation in over forty, very entertaining 10-minute videos. I was totally addicted to it and I highly recommend it. There have since been a Literature series and Green is currently updating a series on American History. For you science buffs, John’s brother Hank has done a biology, chemistry and ecology series. All the videos can be seen on the Crash Course YouTube channel.

Before it took over smartphones, Android was originally destined for cameras
Nearly ten years ago, well before Android became the dominant smartphone operating system it is today, Andy Rubin and his colleagues were designing it as a software platform for cameras. That revelation came from Rubin himself during a presentation at Japan's New Economy Summit. According to PCWorld, Android in its earliest days was intended to improve the connection between digital cameras and PCs. Bringing new app experiences to cameras — a relatively stubborn market at the time — also seemed to be on the radar.
"We thought it would be good if we could build a camera platform with third-party apps," Rubin said. Ultimately though, even before Apple's iPhone had launched to consumers, the mobile trend became clear. "We decided...
