Weekly Reading: Some Interesting Stuff

This is one of the best articles' I have read this year. So many wow moments in this. Here are some excerpts:
When a supernova explodes, the blast wave creates high-energy particles that scatter in every direction; scientists believe there is a minute chance that one of the errant particles, known as a cosmic ray, can hit a computer chip on Earth, flipping a 0 to a 1. The world’s most robust computer systems, at NASA, financial firms, and the like, used special hardware that could tolerate single bit-flips. But Google, which was still operating like a startup, bought cheaper computers that lacked that feature. 

They were relentless optimizers. When a car goes around a turn, more ground must be covered by the outside wheels; likewise, the outer edge of a spinning hard disk moves faster than the inner one. Google had moved the most frequently accessed data to the outside, so that bits could flow faster under the read-head, but had left the inner half empty; Jeff and Sanjay used the space to store preprocessed data for common search queries. 

A list of the best scientific innovations of 2018. A fascinating peek into where we as humans are going. Things like the Iron-Man jet suit, indoor smart garden, shape-shifting vehicle wheels and the world's first migraine prevention drug make the list interesting and entertaining.

New technology is the key reason for today’s high equity valuations, he said: “It’s created this vision of a world for all of us where we can have high growth and no inflation forever.” But the United States has had many periods of technological change since the late 1800s and none ever produced permanent high growth and low inflation.
So China will abandon its link to the dollar. “It’s just not conceivable that the second-biggest economy in the world would take its monetary policy from Washington, DC,” Napier said. He expects an initial devaluation, then a free-floating RMB that allows China to inflate away its debt. And when the currency relationship ends, so will the nirvana of high US growth, low inflation, and high equity valuations.

A fascinating article on how Sweden has managed to be great at creating new start-ups in business and the changes it has put in place over the last 30 years to get where it is today.

How can 2018 be complete without something about graphite ;-)
Over the next five years, demand for graphite electrodes is expected to outstrip supply, keeping prices high. (Capacity is expected to grow by 8 percent annually, but demand should grow by 12 percent.) “We see this uplift as structural,” noted Sumangal Nevatia in a Macquarie Research report in June. “With no substitute, growing demand and limited new supply, graphite electrodes are now more a ‘strategic resource’ than a ­‘commodity.’ ”
