Instead, they’ll be building something that could save your life, and it’s made possible by a drone.

It’s called Project Ryptide, and it’s an automatically inflating life preserver ring that snaps onto your drone. Lifeguards with the Ryptide attachment and life preserver would be able to snap it on within a few seconds, fly over to a swimmer in trouble, and deliver them a life preserver.

And it’s not just lifeguards who could use this. In fact, Piedra said this may come in most handy in places where there is no lifeguard.

“Any casual person going to the beach can bring their drone, and now they can be a sort of lifeguard,” said the project’s leader Bill Piedra. “They could deliver a personal flotation device and keep…

LET THE MACHINE LEARN EVERYTHING! The network is designed as a traditional deep ConvNet, with successions of convolutional and pooling layers, finishing with 2 fully connected layers. The succession of convolutions makes it possible to learn very diverse sets of features, by learning convolutions of convolutions of convolutions (as if we looked at, for example, the blurred embossed image of the edges of an image, but with the actual operation being learned by the system). We learn to read like that! We arrange images in our brain, we learn the characters and associate them with sounds. We practice convolutions of convolutions until we get 100% accuracy. Babies go by images, and then we rhyme with them or say words and little phrases with the images. We keep doing that over time until they train their brain to evaluate images of entire sentences; we still go on for the ones who train themselves to fast reading.

Spark has grown from a gleam in the eye of CEO Zach Supalla to a fully baked prototyping platform. These tiny boards allow you to make programmable Wi-Fi-enabled systems with a few lines of code and a few electronic connections. But Supalla wants to give you more.

The company has just announced the Spark Electron, a cellular-data enabled version of the Spark. It comes in 2G and 3G options with the boards costing $39 and $59 respectively. It comes with a SIM card and Spark will act as an MVNO. They’re offering 1MB of data for $2.99 a month and it will work in the U.S., Canada, and Europe.

In short, this little board will be able to send messages to a central server, for example, almost anywhere in the world without Wi-Fi.

“We’re surrounded by cellular towers designed for our mobile phones and tablets,” said Supalla. “But those same…
