Primer on encryption

Encryption has been in the news ever since Edward Snowden revealed to the world the massive spying operation that the US and its allies in English speaking countries (UK, Canada, Australia, and New Zealand) perpetrates on the communications of people all over the world.

Happiness and longevity

It is always interesting when conventional wisdom is challenged. A new study provides a classic example of the danger of inferring causation from correlation. There have been studies that show that people who are unhappy have higher mortality rates and thus shorter life spans. It has become conventional to think that being unhappy is bad for you. But a new large ten-year study says that rather than unhappiness leading to increased mortality, it is poor health that leads people to be unhappy and that is the reason for the correlation.

Is homeopathy harmless?

Nassim Nicholas Taleb is a statistician and risk analyst. He recently sent out a tweet that defended homeopathy as being harmless and even beneficial since after all people were only taking a placebo and that it may prevent them from over-treatment of marginal symptoms. He followed up with another tweet saying that “Superstitions can be rational if 1) harmless, 2) lower your anxiety, 3) prevent you from listening to forecast by economists & BS “experts””

Self-driving car gets pulled over by police

One of the self-driving cars being tested by Google was pulled over by a police officer for driving too slow, 25 mph in a 35 mph zone. I had not been aware that driving below the speed limit was a primary offense but apparently it is if you are causing a traffic backup behind you. Or maybe not, because the news report is a bit confused about whether it is an offense or not.

The opportunistic attention given to mental health

Whenever there is a mass shooting of random people, as occurs all too frequently in the US, people immediately seize on the issue of the mental health of the gunman (it is almost always a man). Some use it purely opportunistically, in order to deflect attention away from the easy accessibility of guns in the US that enables individual to obtain an arsenal of lethal weaponry with far less effort and time than it takes to get (say) a driver’s license.

Good news on polio eradication efforts

It looks like we are getting really close to the global eradication of polio. The last countries where it had not been eliminated were Nigeria, Pakistan, and Afghanistan but Nigeria has had no new cases of polio for the last year so the African continent seems to be now clear. The remaining cases are in a region of the Afghanistan-Pakistan border but even there only 51 cases have been reported this year and health officials are cautiously optimistic that they can get that area clear too. But until we are sure it is completely eradicated, people all over the world will have to continue to be vaccinated against it.
