Submission + - Solar power boosts opium production (bbc.com) 1

ljw1004 writes: Helmand Province in Afghanistan produces two thirds of the world's opium. Its opium production has more than doubled in the past eight years, due mostly to solar power. "Solar is by far the most significant technological change" in the region for decades. The first solar panels were introduced there in 2013. More recently solar panel installations have doubled every year, and now stand at 67,000. In Lashkargah, the capital of Helmand Province, solar panels are stacked in the market in great piles three stories high. For an up-front cost of $5000, farmers can buy panels and a pump to irrigate their fields, and then there are virtually no running costs. "All this water is making the desert bloom." $5000 is a lot of money — the average dowry is $7000 — but the panels pay for themselves within two years. Farmers used to rely on diesel, which was more costly, unreliable and adulterated which led to frequent machinery breakdowns.

This "is perhaps the purest example of capitalism on the planet. There are no subsidies here. Nobody is thinking about climate change — or any other ethical consideration, for that matter. This is about small-scale entrepreneurs trying to make a profit. It is the story of how Afghan opium growers have switched to solar power, and significantly increased the world supply of heroin. What does this tell us about solar power? That is simple. The story of the revolution in Afghan heroin production shows us just how transformative solar power can be. Don't imagine this is some kind of benign 'green' technology. Solar is getting so cheap that it is capable of changing the way we do things in fundamental ways and with consequences that can affect the entire world."

(Those consequences: far more opium in the world; water table dropping by 3m a year; and a major crisis brewing in 10-15 years when the water runs out and the land returns to desert and 1.5 million people are forced to migrate).

Submission + - How to create my own local TV channel? 3

ljw1004 writes: I want to assemble my OneDrive-hosted mp4s into a "TV channel" for my kids — so at 7am while I sleep in, they know they can turn the TV on, it will show Mr Rogers then Sesame Street then grandparents' story-time then two hand-picked cartoons, and nothing for the rest of the day. How would you do this? With Chromecast and write a JS Chrome plugin to drive it? Write an app for FireTV? Is there any existing OSS software for either the scheduling side (done by parents) or the TV-receiver side? How would you lock down the TV beyond just hiding the remote?

(Why? Because there are good worthwhile things for them to see, but they're too young to be given the autonomy to pick them, and I can do better than Nickeloden or CBBC or Amazon Freetime Unlimited. Also being kids they turn everything into limits-testing and I don't think they're gaining at this stage by testing limits on TV time.)

Submission + - Drug halts decline in Alzheimer's disease (bbc.co.uk)

ljw1004 writes: Alzheimer's disease: researchers are divided on whether it's caused by "beta amyloid" (a peptide found in alzheimer brains) or by "tau protein" (normally used for cellular scaffolding, but can aggregate of control and destroy neurons). Today in Chicago a new drug has been anounced which stops tau aggregation and appears to have halted alzheimer-related decline in 300 clinical trial patients. Do you have friends or family who appear to be dementing? Here is an online questionnaire, part of one used in the clinical trial to diagnose dementia. (disclosure: I made the online questionnaire, and my father is one of the scientists behind the drug.)
