Facebook’s Profit Propelled by Mobile

Facebook, based in Menlo Park, Calif., said it had about 1.32 billion monthly users around the world in June, with more than a billion of those people using the service at least partly on mobile devices.
Revenue was $2.91 billion, up 61 percent from $1.81 billion during the same period last year.
Mobile devices accounted for nearly two-thirds of Facebook’s revenue, which at this point mostly comes from ads shown on the Facebook website and apps. However, the company is beginning to supplement that with ads on other sites.
... The company accounted for 5.8 percent of the world’s estimated $120 billion in digital ad revenues in 2013, and it captured 17.77 percent of mobile ad spending, according to the research firm eMarketer.
MIT students make 3D-printed ice cream
If your ice cream could look like anything in the world, what would you choose? A new machine could 3D print your ice cream in 15 minutes. The Guardian reports.
Three students from MIT have hacked together a 3D printer that can produce edible Mr Whippy-style ice cream in any shape.
Kyle Hounsell, Kristine Bunker and David Donghyun Kim developed the contraption – a modified version of an existing 3D printer connected to a “soft serve” ice-cream machine – as part of a graduate project in MIT’s additive manufacturing department.
The students built a cooling system using liquid nitrogen to fix the ice cream in place as it was squirted out of the 3D printer’s nozzle into the desired shape. The instant cooling allowed the printer to build up the ice cream layers just as a traditional extrusion-based 3D printer squirts down layers of plastic.
“The main reason we feel an ice cream 3D printer is an important addition to current additive manufacturing technology is that it interests children,” the MIT students explained.
The students had to balance the accuracy and printing resolution of the printer to enable interesting shapes and creations with the speed of printing, as no one wants to wait 30 minutes for their ice cream to appear.

Drone users swarm for Burning Man registration, cap nearly reached
As of late Thursday, more than 150 registrants submitted requests to use drones at the annual week-long counterculture gathering in Nevada's Black Rock Desert. When organizers announced the registration Tuesday, it set limit the number of people allowed to use devices to 200. [via The Examiner]
Though registration was required at 2013’s event, organizers believed limiting the number of flyers to this year to 200 would more than accommodate the number of people intending to fly.
“We don't think we had anything close to that last year. We'll see what we get,” Graham said Wednesday.
But by 11 p.m. Thursday night, 156 attendees had registered for this August’s event.
Despite the numbers, Graham said Friday morning that the organization doesn’t believe it will need to increase the cap.
“We had a rush of applications when we announced registration,” he explained. “It has slowed to a trickle. We think the 200 cap is good and was based on our ability to staff and properly support the effort.
