Do we still need constellations of satellites for networking when we have drones that can take off and land on their own, be serviced, and go back up and stay there for a year?

The title and summary confused me and made me want to read the article, breaking the Slashdot tradition. Is the discovery that black holes are merging generally, per how the summary starts off "now we have evidence that hundreds of thousands of them are merging". Or is it that black hole pairs are merging, and the summary says shortly thereafter "the population of massive black hole pairs that are merging"?

Or is it that the way that the general merging is happening is one pair at a time, such as with Sagittarius and Andromeda, which just happen to the the two that are merging the closest to us, and which will result in a binary system forming? will the binary system then merge with another supermassive black hole? Or does it have to then merge with another binary system? Or is is a one level merge event, and once every supermassive black hole has participated in one merge event, then it's all done?

I got confused enough and got so any terms thrown at me in the summary hinting that something got grossly oversimplified in the title.

Don't they know the right forum for posting stuff that they want to later blame on AI or bitter chicken?

There are oil & gas fields releasing over 25000 kg of methane all over the world. That's per hour, by the way. Good to see that after all the diversions into subsidies that gives us at best incremental benefit in cutting greenhouse gases, the US is doing something that can have immediate and substantial impact and not just greenie points.

"All these athletes" implies some huge percentage. But seems like the rate is consistent with tests that aren't 100% accurate, and so sme athletes or support staff unknowingly spreading it.

Sure, that could happen. But given that host nations with strong sporting cultures do well in Olympics, is China's performance unusually good?
Also, do we know that no Chinese athletes tested positive?

A whole parallel world of cognition that interacts with ours. Ordinary and spooky simultaneously.

Exactly! They made it narrower than the tablets that pass for phones these days. But too tall. So it isn't pocketable. its just different for the sake of being different. Won't appeal t to the "media consumption" crowd, nor to those who want to carry something that isn't noticeable until you need it.

Do one off the bat, right?

OK, I thought the document you posted had that info, not the document summarized by the document you posted.

As for deterrent effect, you can't know directly, but they have numbers for crime before cameras and crime after. Some of the reduction could reasonably be attributed to cameras.

Hmmm... that is data for private security cameras, which is a more general category that doorbell cameras. And it doesn't say anything about how effective they were - if they played any role in solving crime.

I'm interested in the trade-off between giving them access to data from a private device and the reduction in crime. Or deterrence in crime.

"We've had a lot of success in terms of deterring crime and solving crimes that would otherwise not be solved as quickly."

Cool. So what is a lot of success? Where's the data? What's the trade-off here?

I have no fondness for Tesla or the "electric car revolution", but car dealers should not be the ones deciding the future either. In fact, the dealership model (in the US) is to make money with volume - which mean cheap, under-optioned and option-packaged cars. This means that unless you are very very motivated, you can't buy a vehicle that is best for you. Dealers can move cheap cars the fastest - they source them with pre-packaged options (e.g. if you want active lane departure prevention, you have to get the top of line model with nappa leather, or go without), and attach the most attractive financing to them. This is why the European car market is so much more diverse, but also more expensive. With the volume of cars sold in the US, dealers can make money selling nicer cars with a la carte options too, but it is more work for them.

Look around you. Look at the sea of mediocrity on the American roads - SUVs barely different from each other except for their hood ornaments, differentiated basically by size from mere super-size to megaladon. Insipid inefficient power-trains. People buying expensive name brands with the barely more options than air-conditioning. The dealership model did this.

Don't buy mediocre junk. Spend a little more and don't settle, maybe it means you have to special order (or buy direct from manufacturer if possible). But you won't be looking again in a couple of years because you couldn't live with the compromises that you'd convinced yourself are worth making to drive with something off the dealership lot today.

The best? That's a high bar. TV stations broadcast Full HD over the air, and this is incapable of receiving them. Sure, the TV monitor you connect to may receive them, but then you're using its tuner and app to watch.
