Submission + - They built an artificial pancreas using a Raspberry Pi and hacked insulin pump->

mattydread23 writes: Dana Lewis was diagnosed with Type 1 diabetes when she was 14. To manage it, like most diabetics, she pricked her finger a dozen times a day to measure her glucose levels and used an insulin pump. But doing math in her head to figure out the right amount of insulin to add was a pain, and sometimes she slept through the alarm that was supposed to wake her up if her levels got too low. So she and her boyfriend (now husband), a Twitter engineer, did the natural thing for two geeks: They built an artificial pancreas.

Submission + - Meet microservices: The next big trend after cloud computing->

mattydread23 writes: There's an old proverb among engineers of all stripes: "Better, cheaper, faster — pick two." But when it comes to the mobile apps that increasingly rule our world, we demand all three, every single day. So big tech companies like Amazon, Netflix, and PayPal have completely rethought how they build their products, using bleeding-edge technologies that they developed themselves to take one big problem and make it a lot of smaller ones. And startups are starting to jump aboard too, as this trend makes it much easier to get started and stay lean. Sort of like the cloud computing was 5 years ago.
