The Juicero story is getting a reaction, and I think this nails why: "This is everything wrong about Silicon Valley in one note. A sort of unique sense of out of touch that makes people who ship chopped vegetables at 4000% markup think they are changing the world because of a nice looking app."

Analysis of Google's Tensor Processing Unit (for deep learning) by AWS Distinguished Engineer James Hamilton: "For machine learning inference, this part is more than an order of magnitude faster than an Nvidia GPGPU while being more than an order of magnitude less expensive. This is the power of workload hardware specialization and we are going to see a lot more of this over the next decade ... This is really fine work"

Nice, easy, practical optimization here, using battery backup to optimize gas power plants by being able to skip the very expensive bits for gas turbines (sitting in standby because of lengthy startup times). Love this kind of stuff, low hanging fruit with major impact.

Great Xkcd comic, don't miss the mouseover: "They say you can't argue with results, but what kind of defeatist attitude is that? If you stick with it, you can argue with ANYTHING."

Nice, take multiple pictures, get out a good scan.

I'd say the only thing that might be better is if you could just move your phone around over the document or photo, and it took video, then combined all the video frames to get the scan. The stitching might be easier (each frame would be very similar, less movement) but the resolution might be an issue, I suppose. Still, the greater information available should enable more, and the ease of use would be better.

Self-driving hype resulting in lawsuits:

https://www.bloomberg.com/news/articles/2017-04-20/tesla-sued-over-dangerously-defective-autopilot-software-j1qp271l

By the way, the article quotes Tesla as saying "it’s never claimed its vehicles are armed with full self-driving capability." But the page at

https://www.tesla.com/autopilot

currently says, "Full Self-Driving Hardware on All Cars. All Tesla vehicles produced in our factory, including Model 3, have the hardware needed for full self-driving capability at a safety level substantially greater than that of a human driver."

Interesting data on how Amazon wants to grow, their open job postings. It's a little hard to interpret without knowing existing team sizes (as a lot of this is just dealing with attrition, not growth), but what seems clear is that AWS and devices (like Alexa) are major investment areas and growing, retail not so much.

Remarkable if this is actually possible at scale.

"Something is wrong when Juicero and Theranos are in the headlines, and bad behavior from Uber executives overshadows actual innovation ... These stories are embarrassing, yes. But there's something deeper going on here. Silicon Valley, an international treasure that birthed the technology of our age, is being destroyed."
