The ReWalk™ exoskeleton suit uses patented technology with motorized legs that power knee and hip movement. Battery-powered for all-day use, ReWalk is controlled by on-board computers and motion sensors, restoring self-initiated walking without needing tethers or switches to begin stepping. ReWalk controls movement using subtle changes in center of gravity, mimics natural gait and provides functional walking speed. A forward tilt of the upper body is sensed by the system, which triggers the first step.
Years ago, Charlie, a highly respected orthopedist and a mentor of mine, found a lump in his stomach. He had a surgeon explore the area, and the diagnosis was pancreatic cancer. This surgeon was one of the best in the country. He had even invented a new procedure for this exact cancer that could triple a patient’s five-year-survival odds–from 5 percent to 15 percent–albeit with a poor quality of life. Charlie was uninterested. He went home the next day, closed his practice, and never set foot in a hospital again. He focused on spending time with family and feeling as good as possible. Several months later, he died at home. He got no chemotherapy, radiation, or surgical treatment. Medicare didn’t spend much on him.
It’s not a frequent topic of discussion, but doctors die, too. And they don’t die like the rest of us. What’s unusual about them is not how much treatment they get compared to most Americans, but how little. For all the time they spend fending off the deaths of others, they tend to be fairly serene when faced with death themselves. They know exactly what is going to happen, they know the choices, and they generally have access to any sort of medical care they could want. But they go gently.
Tomorrow is the funeral for Aaron Swartz, the programmer and sometime activist who killed himself last Friday, while facing federal trial. No one knows, or will ever really know, what caused Swartz to take his own life. But his suicide, in the face of possible bankruptcy and serious prison time, has created a moment of clarity. We can rightly judge a society by how it treats its eccentrics and deviant geniuses—and by that measure, we have utterly failed.
Programming is changing. The PC era is coming to an end, and software developers now work with an explosion of devices, job functions, and problems that need different approaches from the single machine era. In our age of exploding data, the ability to do some kind of programming is increasingly important to every job, and programming is no longer the sole preserve of an engineering priesthood.
Mindstorms EV3 runs on new Linux firmware that's ready for Android and iOS control out of the box, creates an overall more hackable platform and allows further programming on the core Intelligent Brick itself; accordingly, there's an SD card slot for local storage. A built-in infrared sensor expands the possibilities for a more autonomous design, as well -- Lego suggests that EV3 constructs can follow other moving gadgets, or even their creators, around the room
