If you’ve ever lived with roommates, chances are you shared a “transactive” memory system with them. One person might have remembered to pay the bills, while another knew the contact details of the plumber. It’s common to find social systems that share the information needed by a group across all the members of that group. Systems like these make life easier for individuals, who need only keep track of who knows which nugget.

Transactive memory systems are a common feature of human social groups, but they can be technological, too—and in the case of the Internet, the relationship can be a pretty powerful one. There are already indications that we treat the Internet like a transactive memory partner, remembering only where to find information, rather than the content itself. But could we also be blurring the boundary between our own internal knowledge and the easily accessed knowledge available via search engines? A group of researchers at Yale University think that we are. Read more

On Flickr, it’s cool nature shots. Instagram loves the Kardashians.

But favorite subjects come and go, while the viral cycle lives on. What if you could predict the kinds of photos most likely to strike a nerve? Given the incredible amount of data available on how online users engage with images, is there a way to measure the objective qualities of an image’s shareability?

A zombie network of home routers highlights the importance of prioritizing smart appliance security.

Plenty of science-fiction stories feature ordinary household appliances staging a revolt. In an episode of Futurama, toasters and home robots rise up against their human oppressors. Two trends are now starting to make such scenarios seem less far-fetched.

One is the wave of Internet of things devices being developed for homes—on full display at the CES trade show last week. The other is the increased hacking of home networking gear—as demonstrated by a zombie horde of home network routers discovered recently.
