The health benefits of fasting without feeling like you’re starving — the “fasting mimicking diet” from USC

Recently the media has been spreading the news about the USC “fasting mimicking diet” that seems to achieve the well-known health benefits of fasting while still letting you eat some food.

Here’s the science and an interview where the researcher warns about “attempting the fasting mimicking diet without first consulting a doctor and seeking their supervision throughout the process”.

The formula is to mimic fasting 5 days per month for 3 months, by on the first day eating 1090 calories as 10% protein, 56% fats, 34% carbs, and then on the next 4 days eating 725 calories as 9% protein, 44% fat, 47% carbs.

If we suppose that protein and carbs contain 4 calories per gram, and fat contains 9 calories per gram, then on the first day 27 grams of protein, 68 grams of fat and 97 grams of carbs, and on the next 4 days 16 grams of protein, 35 grams of fat and 85 grams of carbs.

Simplicity and the ability to take a beating: why there are 75 million AK-47’s

According to Ethan Trex in “What Made The AK-47 So Popular?”

One might think that the AK-47’s wild popularity stems from pinpoint accuracy. Think again. The standard issue AK isn’t particularly accurate; it’s best in relatively close-range combat situations rather than distant engagements.

The AK-47’s major selling points are its simplicity and its ability to take a beating. The rifle was designed to be easy to use, easy to repair, and reliable. The ruggedness of the gun makes it the perfect weapon for dirty, sandy conditions or for soldiers who might not be super disciplined about maintaining their firearms. Its simple firing mechanism means that the gun jams very rarely. Depending on conditions of use, an AK-47 can have a service life of anywhere from 20 to 40 years.

If you were successful at that, would it even move the needle?

According to Tom Darden in a great interview I recommend

I don’t like to be involved with things where if you were successful with it, it wouldn’t move the needle. A lot of things fall into that category. In life, or business, or dealing with the environment. My goal is to work on things that at least if you were successful, they matter.

“Innovation is a change of practice that displaces other practices already in place.”

According to Fernando Flores

The common sense about innovation is revealed in the popular stories that say that innovation is the product of creative people constantly inventing new technologies based in science. Yet innovations arise without creativity, new technology, or new science, and some creative technologies produce no innovation. Having a clear plan and strategy is also overrated. Some innovations come without these, and many plans and strategies do not produce innovation. Innovation is a change of practice that displaces other practices already in place. Inventing creative technology does nothing: people must take up new practice.

“I’m so privileged to be able to talk to customers; they are a great source of problems.”, says 2014 Turing Award recipient

According to Leah Hoffman

A serial entrepreneur long before the term became commonplace—and a data geek before the age of big data—ACM A.M. Turing Award recipient Michael Stonebraker pioneered techniques that were not just crucial to making relational databases a reality, but that continue to be used in almost all modern systems. […] Since 2001, he has served as an adjunct professor at the Massachusetts Institute of Technology (MIT), while forming a total of six start-ups in 14 years […]”

One Q&A with Stonebraker is

You are currently CTO at three start-ups and co-director of MIT’s Intel Science and Technology Center for Big Data. How do you organize your time?

I fight whatever fire is most pressing. Typically I’m at MIT three days a week, and at one or another startup two days a week, but it varies. There are travel requests and customer visits, and they come on their own schedules. I’m so privileged to be able to talk to customers; they are a great source of problems. They’ll tell you why your stuff doesn’t work, and then you get to fix it.

According to Neil Savage

Samuel Madden, a colleague at MIT who studies database systems, believes Stonebraker founded these companies to demonstrate that his academic ideas have real-world applications. “He’s very singularly driven with a vision of the way the world ought to be,” Madden says, “and remarkably most of the time this vision turns out to be right.”

For undergraduates just getting into computer science, Stonebraker’s advice is, “Learn how to code, and code well, because whatever you do is going to involve implementation.” For Ph.D. students trying to figure out where to focus their attention, he suggests talking to real-world computer users. “They’re happy to tell you why they don’t like or do like any given technology, so they’re a wonderful source of problems to work on.”

Cold fusion with COP from 20 to 80

According to Torkel Nyberg in First Hand Information from Visitors of the Industrial Heat E-Cat Customer!

I know first hand from very reliable sources that themselves have visited the Rossi/Industrial Heat E-Cat customer that the plant works very well. This has been verified both by measurements made by the customer and by significantly reduced electricity bills. The plant seems to be able to produce heat from electricity with a COP in the range of 20-80 depending on the level of self-sustain-mode applied.

Following up to Cold fusion is real — independent test of Industrial Heat’s E-Cat nickel/lithium/hydrogen reactor.

The Rex Neo chip: 10x to 25x increase in energy efficiency for same performance

According to Nicole Hemsoth

When Rex Computing CEO, Thomas Sohmers, was working with embedded computing systems for military applications at MIT at age 13, his thoughts turned to much larger scale systems. For exascale-class computing, he realized there were many lessons to be carried over from embedded computing that could potentially have an impact on the toughest challenges that lie ahead—balancing the performance demands with overall power efficiency and scalability of both the hardware and software.

The result of his research is an up and coming chip called Neo, which brings to bear a new architecture, instruction set, and core design that scraps a great deal of what Sohmers deems unnecessary about current cache architecture, snaps in a new interconnect, and if his assumptions are correct, can do this in a power envelope and performance target that goes beyond the current Department of Energy requirements for exascale computing goals, which they hope to realize in the 2020 to 2023 timeframe.

Sohmers says that the national labs are already expressing early interest in the 64-bit Neo cores, which are 1/145 the size of a fourth generation Haswell core and 1/27 the size of a 32-bit ARM Cortex A-15. He expects to deliver a 256 core chip by the end of 2016 at the earliest using a 28 nanometer process, which will offer 65 gigaflops per watt. Successive generations will use 10 nanometer or 7 nanometer processes as those roll out. “Current proposals for exascale in 2022 are for 20 megawatts, but it’s definitely possible to do better than that within five years,” he noted.
