Broadish reply, so an entry point for my question about uneven winds: How big before different turbine blades are in zones with different wind speeds or directions and how would that affect power production?

Sorry, I can't remember the details after so many years, and I'm not sure how much they matter. I suspect it was mostly the recommendation engine on the website, but that's a book-specific black hole. Most product categories can't be abused that much. I vaguely remember negative reactions to the kinds of reviews that were being brought to my attention, but that's actually the opposite of a black hole problem. On that side Amazon has (for most products) collected far more reviews than you want to read and the trick (as Amazon sees it) is how to show you the reviews that will most quickly induce you to buy the product--again subject to the hidden constraint of favoring sales that help Amazon more.

However even if I could remember every detail, I shouldn't be blind to changes. It is possible that Amazon could have undergone "moral improvements" since way back then. And I should be keeping my eyes open to see signs of such changes. I think I have and have not seen them.

Astronomers analyzed the infrared flow of dust and detritus left over from the formation of a baby star called HOPS-315, finding tiny concentrations of hot minerals that will eventually form planetesimals – the 'seeds' around which new planets will grow.

Comment My personal boycott of Amazon (Score 0) 45

My second and final Amazon purchase was decades ago. Both purchases were books, but the website smelled of evil. To high heaven, and I decided I wanted no part of it.

Nothing I've learned since then has improved my sentiments towards Amazon and all things Amazon.

Solutions? Can't get there from here. Sad to report that's how it looks to me.

And yet I wonder how bad it has gotten. For example, how good is Amazon at pulling the suckers' triggers? I think the biggest mind trick would be knowing when to show a negative review that will trigger a sale. Much sneakier and more sophisticated that merely putting the most profitable (for Amazon) products higher in the search results.
