A more in depth look at the factors causing high fertilizer prices:

tl;dr: high natural gas prices, weather caused production delays, COVID caused production/shipping delays, power shortages in China (a major exporter) resulting in lower production

"Flattening the curve" is about not overwhleming hospital resources, to avoid non-COVID avoidable deaths spiking.

Counterpoint: high quality journalism must be well funded, and funding based on advertising and 'clickbait' undermines quality. So paywalls it is.

If you have enough electricity to do that, you can just put into EV batteries directly and skip the hydrogen middle man.

It's interesting that you set the threshold there (I presume you meant 'beat the bottom 80% of drivers'). Rationally, we should be happy if their driving performance is above average. I fear that the public (and the courts and the insurers, etc) will require airline levels of per-mile safety and still be wary.

I don't think your intuition is the problem:

The Google doc doesn't say. The article says:

It probably depends on whether the suspect was on foot or driving.

New comment by _rpd in "Long-haul symptoms affect majority of Covid-19 patients, UA study finds"

_rpd — Sun, 22 Aug 2021 04:08:01 +0000

Actual paper ...

> Among participants who tested positive for COVID-19, 68.7% experienced at least one symptom after 30 days, marking the distinction for long COVID. This prevalence increased to 77% after 60 days of follow-up. Researchers also found that individuals who experienced long COVID were more likely to be less educated, have seasonal allergies and pre-existing health conditions, and self-report greater symptom severity than people without long COVID.

If you think about what payment processors actually do, dealing with fraud is one of the main costs. There's a lot of fraud associated with porn related transactions, so it can make financial sense to just drop the entire transaction category.

Wired was always a gossip magazine, but now it is just a gossip magazine. It's sad.
