Uploading tourist photos is a popular activity on photo sharing platforms. These photographs and their associated metadata (tags, geo-tags, and temporal information) should be useful for mining information about the sites visited. However, user-supplied metadata are often noisy and efficient filtering methods are needed before extracting useful knowledge. We focus here on exploiting temporal information, associated with tourist sites that appear in Flickr. From automatically filtered sets of geo-tagged photos, we deduce answers to questions like "how long does it take to visit a tourist attraction?" or "what can I visit in one day in this city?" Our method is evaluated and validated by comparing the automatically obtained visit duration times to manual estimations.

or the last few years we have studied the diffusion of private information about users as they visit various Web sites triggering data gathering aggregation by third parties. This paper reports on our longitudinal study consisting of multiple snapshots of our examination of such diffusion over four years. We examine the various technical ways by which third-party aggregators acquire data and the depth of userrelated information acquired. We study techniques for protecting against this privacy diffusion as well as limitations of such techniques. We introduce the concept of secondary privacy damage. Our results show increasing aggregation of user-related data by a steadily decreasing number of entities. A handful of companies are able to track users' movement across almost all of the popular Web sites. Virtually all the protection techniques have significant limitations highlighting the seriousness of the problem and the need for alternate solutions.

In this work, a novel mobile browser for geo-referenced pictures is introduced and described. We use the term browser to denote a system aimed at browsing pictures selected from a large set like Internet photo sharing services. The criteria to filter a subset of pictures to browse are three: the user's actual position, the user's actual heading, and the user's preferences. In this work we only focus on the first two criteria leaving the integration of user's preferences for future developments.

people rarely held on to money in the form of cash for any length of time, for the most part due to lack of access to banks and/or the high cost of maintaining an account proportionate to their incomes. Cash was rapidly converted to goods based on priorities and these 'goods' acted as insurance (silver), savings (buying building materials on a piecemeal basis as cashflow allowed until the house could be built), a cushion aka insurance (selling a pig for an emergency or eaten for food) and finally investment (milk bearing cow, young piglets to rear to maturity, etc).

Eating local food when it’s in season is an increasingly popular goal amongst people who are interested in eating the tastiest, healthiest food while also being good to the environment. Knowing what’s available in your area at a given time of year is often difficult to determine, so we’ve taken on the task of collecting data from a variety of sources and presenting it all in the most understandable of ways.

What is "City In A Bottle"?

City In A Bottle is an interactive project bordering between art, science and gaming, funded by the Flemish Audiovisual Fund.

The game environment is based on the AI-principle of emergent behaviour. Organisms (plants and insects) start off with basic behaviouristic rules and goals. If an opponent is edible, attack it. If an opponent is stronger, flee. When cornered, fight back. Hide in a flock of relatives to minimise the chance of being singled out. Follow a food trail marked by a relative. Expand and defend a productive environment. Grow colourful feathers/flowers to incite reproduction.

Complex social behavior then emerges by itself as organisms interact with each other. Species with a good strategy will survive and evolve over time, will adapt, will look different. The gaming enviroment changes procedurally, there is no preprogrammed story or pathway. We don't control the biotope. The creatures will find their own way and either co-exist or fight for limited space and food.

At the Taste3 conference, chef Dan Barber tells the story of a small farm in Spain that has found a humane way to produce foie gras. Raising his geese in a natural environment, farmer Eduardo Sousa embodies the kind of food production Barber believes in.

The Rooftop Gardening Project is an innovative partnership between Alternatives, an international cooperation network, and Santropol Roulant, a community organisation in Montreal. Together we are making widespread rooftop gardening a reality in Montreal and around the world. Our novel soil-less gardens empower urban residents to produce their own food, green their neighbourhoods and build healthy communities.
