jtoberon | 8 months ago | on: Cancer DNA is detectable in blood years before diagnosis

Imagine a reader who is not one of your lucky “most” majority. Imagine a reader whose cancer was not caused by the bad lifestyle decisions that you listed. Put yourself in the position of somebody who undergoes extensive surgery/radiation/chemotherapy and then lives with the side effects of these treatments. Consider what it’s like to live with the fear of recurrence even after such treatment. Then maybe you’ll understand why people might be excited about the potential of this sort of screening.

Disclosure: I work at AWS.

Here are some examples from my team’s 2019 work: We contributed numerous changes to containerd. We open sourced firecracker-containerd, and we also created a Go SDK that others are using to work with Firecracker. We contributed to Debian and the Debian kernel team. We contributed to Envoy. We collaborated with a number of communities, including Kata Containers, Red Hat’s Clair, and the Open Container Initiative. All of these examples are sustained investments, not one offs.

To clarify, an AWS customer has a shared responsibility to describe the security of their systems including how they use AWS tools, and in this respect Amazon is no different than other AWS customers.

Question for the author: how do you actually deploy your model? Do you have a dependency on Spark in your production system?

I'm not 100% sure what you mean by utility real-time programs, but yes, this probably is they meant. Nest knows where you live (I don't mean that in a creepy way), and they can help you enroll in what are called "demand response" or "load control" programs in your area. When you enroll, you get an incentive like a bill credit or a free thermostat, and you give the utility permission to turn your AC off for a little while at some point during the summer.

Many of these utility programs actively recruit customers, so chances are (a) you'll get a chance to sign up even if you own a different type of connected (e.g. WiFi) thermostat, and (b) the sign up process won't be hard.

FWIW, the Lux Geo can run on on 24VAC, AA batteries, or micro-USB. I don't know how long the batteries last though.

There are lots of reasons why most fancy thermostats need a lot of power. For example, a fancy screen is hungry, WiFi is an expensive protocol (e.g. as compared to ZWave), etc.. Compare the Lux screen to the Nest, and you'll see at least one reason why they think they can get away with batteries.

Another option, patented by Honeywell I think, is called "power stealing." Here's an interesting article on the subject: https://www.ecobee.com/2014/01/the-problem-with-power-steali....

jtoberon | 11 years ago | on: Hardware startups should consider local manufacturing

In the NYC area, there's http://www.refactory.co/. I used to work with these guys, and they know their stuff.

They argue in favor of both designing and manufacturing locally. A quote from their blog: "If you kind of just prototype something and bring it to China expecting that then thousands of these things can be made easily without understanding the processes and materiality of manufacturing, that is gonna be a big problem for you. What works is when the design process is iterated alongside the manufacturing process."

EnergyHub, Brooklyn, NY

We build a IoT platform for connected thermostats. Together, our partners have already sold over 100,000 EnergyHub-powered devices, and soon we will be managing 1 million devices.

Our easy-to-use web/mobile apps help people save money by, for example: figuring out the most efficient time to run your heat or AC; using geofencing to turn things down when you're not home; and providing customized tips to help guide your decisions. We also run critical parts of the Smart Grid by linking our thermostat customers to Demand Response programs in the US and Canada.

You will have the opportunity to work on all aspects of the software: web and mobile applications, the distributed back end system including the communication layer to connected thermostats, analytics that drive efficiency, and the tools that we use. We use modern tools, and we're open to trying out new technologies, languages, and ideas.

To apply, please send your resume and a brief note about why you're interested in EnergyHub to josh at energyhub.net.
