Inside Google’s Quest To Popularize Self-Driving Cars | Popular Science
"While various companies are developing self-driving-car technology, Google’s is the most advanced. Once a driver activates the autonomous mode, the vehicle’s drive-by-wire system transfers control of the brake, gas, and steering to an onboard computer. The vehicle’s roof-mounted lidar (or light detection and ranging) unit probes 360 degrees with 64 laser beams, taking more than a million measurements per second. This data forms a high-resolution map (accurate to about 11 cm) of the car’s surroundings. Prebuilt navigation maps indicate static infrastructure, such as telephone poles, crosswalks, and traffic lights, which enables software to quickly identify moving objects, like pedestrians and cyclists. These targets are clustered together and tracked so that algorithms can process the traffic situation and plot a path safely through it."
Curiosity about life in all of its aspects, I think, is still the secret of great creative people. —

1. Determine your values. Undoubtedly my top strategy for being effective is to work backwards from death. Imagine your last few seconds on Earth and the life you have lived. What was important to you? What were your most proud contributions in life? What do you hope to be remembered for? The bottom line is that you cannot gauge ‘effectiveness’ without first determining what you value.
A sweeter soda: when will gum arabic be violence-free?
Gum arabic is a stabilizer used in food products like chewing gum and soft drinks (soda). It is a natural product derived from the sap of the acacia tree.
In Sudan, a global commodity like gum arabic can help local farmers survive harsh economic conditions in the war-ravaged country.
In 2007, John Ukec Lueth Ukec, Sudan’s ambassador to the United States, claimed that 80% of gum arabic imported for use in the U.S. came from Sudan (Washington Post).
This week, the battle over land to grow gum arabic in Darfur left 64 people dead.
