Ces si désuètes alertes terroristes sur smartphones
Un avis de recherche envoyé sur les mobiles aurait facilité l’arrestation du suspect dans le récent attentat à la bombe à New York. Mais cette technologie paraît bien primaire. Alors, quid de Facebook?

How Much Do Your Text Messages Contribute To Global Warming?
All carbon footprints are about bang for buck. So it's: How much does text messaging do for our lives? Against: What's the impact? NPR reports.

quotemarksright.jpgWhen we wrote this a few years ago, we estimated that the carbon footprint of all the world's text messages to be 32,000 tons of CO2e per year. By now, it will have grown quite a bit, but 32,000 tons is still a tiny figure for all the world's text messaging.

... The estimate we made for an email was about 4 grams (of CO2e). So we're comparing 4 grams for an email and 0.014 grams for a text message, so we're talking about a factor of 300 between the two.quotesmarksleft.jpg

Extreme Tech reports on some of the most interesting new developments and provided some updates on a few of the vendors from last year.

The Good Drone

Drones that catch other drones by shooting nets at them
Michigan researchers develop a drone that can shoot a net to capture other drones

Authorities are still figuring out how to deal with rogue drones. Shooting them down or disabling them can be very hazardous, since a downed drone could fall in the wrong place, or in an extreme case could contain explosives. Some manufacturers, meanwhile, are building firmware into their drones that prevents them flying near airports or near the White House. The Telegraph reports

quotemarksright.jpgResearchers at Michigan Technical University has come up with another solution - a drone that can shoot a net to capture other drones.

The drone, which can be controlled by a human or fly autonomously, fires a net on a string from up to 40 feet that opens up after being flown. It then entangles the other drone, and can fly away to safety.quotesmarksleft.jpg
