The idea of progress
Do you consider the invention of smartphones a progress?
You can talk to your friends at any time of the day (or night!), keep in touch with friends and family abroad, read your emails, see your friends’ holiday photos on Facebook, comment on the news on Twitter, download music, play games………….
But how many hours do you actually spend on your phone? Have you ever counted?
Do smartphones bring people closer through modern technology or are they making us more isolated? Technology and smartphones are not bad, but they can take too much time out of our lives. They can be major distractions that hinder our relationships.
Another disadvantage of smartphones is the amount of waste generated: new models are constantly being released, creating a “need” to have the latest model. But what do you do with your old phone? Do you sell it? Exchange it? Recycle it? Put it in a drawer?
Teens are embarrassed to even be associated with the social network as more and more parents attempt to ‘friend’ their children
eenagers are turning their back on Facebook ‘in their droves’ and switching to simpler social networks and messaging apps, new research has found.
Not only are 16-18 year olds moving on to rivals such as Snapchat, Whatsapp and even Twitter, teens are embarrassed to be so much as associated with Facebook, as their parents adopt the network, researchers said.
“Where once parents worried about their children joining Facebook, the children now say it is their family that insists they stay there to post about their lives,” said Daniel Miller, a Professor of Anthropology at University College London, who works on the Global Social Media Impact Study.
“Parents have worked out how to use the site and see it as a way for the family to remain connected. In response, the young are moving on to cooler things.
“What we’ve learned from working with 16-18 year olds in the UK is that Facebook is not just on the slide, it is basically dead and buried.”
Prof Miller, writing on academic news website the Conversation, added that the research found that “slick isn’t always best” as even the teenagers that took part in the study admitted that Facebook is technically better than its rivals.
“It is more integrated, better for photo albums, organising parties and more effective for observing people’s relationships,” he said, yet other factors are much more important to teens – namely the fact they are likely to get a friend request from their mum on Facebook.
“You just can’t be young and free if you know your parents can access your every indiscretion,” he said.
“It is nothing new that young people care about style and status in relation to their peers, and Facebook is simply not cool anymore.”
Instead, rather than using the network to communicate with each other, teens use Facebook as a link to older family and older siblings who have gone to university.
“To prevent overgrazing as others beasts have occupied its terrain, Facebook has to feed off somewhere else. It has thereby evolved into a very different animal,” Prof Miller concluded.

NEW YORK (CNNMoney) — A 3D food printer sounds like something out of Star Trek, but it’s not out of this world. It’s up and running at the French Culinary Institute in Manhattan — and in five years, it could be in your home.
As part of a project at Cornell University, a group of scientists and students built a 3D printer and began testing it out with food. The device attaches to a computer, which works as the “brain” behind the technology.
It doesn’t look like a traditional printer; it’s more like an industrial fabrication machine. Users load up the printer’s syringes with raw food — anything with a liquid consistency, like soft chocolate, will work. The ingredient-filled syringes will then “print” icing on a cupcake. Or it’ll print something more novel (i.e., terrifying) — like domes of turkey on a cutting board.
“You hand [the computer] three bits of info: a shape that you want, a description of how that shape can be made, and a description of how that material that you want to print with works,” says Jeff Lipton, a Cornell grad student working on the project. Lipton is pursuing a Ph.D. in mechanical engineering.
The project came out of Cornell’s Fab@Home venture, headed up by associate professor Hod Lipson. Started in 2005, the project aims to create do-it-yourself versions of machines that can manufacture custom objects on-demand. The group started experimenting with food fabrication in 2007.
Lipton thinks food printing will be “the killer app” of 3D printing. Just like video games fueled demand for personal computers 30 years ago, he thinks the lure of feeding Grandma’s cookie recipe into a printer will help personal fabricators expand beyond the geek crowd.
“It’s really going to be the next phase of the digital revolution,” he says.
David Arnold, director of culinary technology at the French Culinary Institute, has been testing out the technology since October 2009. He loves the experimentation it makes possible.
“One of the main things I hope this machine will let us do is create new textures that we couldn’t get otherwise,” he says. “This is the first time I’ve really seen this happen.”
That could draw in chefs and restaurateurs. But Arnold also thinks a 3D food printer will have mass appeal.
“This would be a slam dunk for cookies at holiday time,” he says. “Anything that requires a high level of precision that people don’t usually have with their hands, in terms of making icing or decorations, this thing can perform amazingly well.”
Because it’s an academic project, the 3D food printer isn’t commercially available — yet. The Fab@Home project has the blueprints for free online, and dedicated hobbyists can use them to build their own. One retailer, nextfabstore.com, offers an assembled version for sale — starting at a mere $3,300.
Entrepreneur Jamil Yosefzai plans to be on the forefront of commercializing the technology. His New York City-based startup, Essential Dynamics, is working on a version that can be sold to the first wave potential customers: pastry chefs and tech early adopters.
Yosefzai thinks his version of the printer will kinetically retail for around $1,000, but he expects that price tag to eventually fall to $700 or so. And he predicts that the technology could become a household staple within a decade.
“It comes down to comfort level, and that will expand as the [technology] goes more and more into schools and everywhere else,” he says. “Sort of like computers — the kids picked it up first, then the parents picked it up, and once everybody has an acclimation to it, they’ll be printing left and right.”
