The radars are not that bad. They are simply lying.

Actually file cabinets typically stored the papers themselves sideways. So this would most be like the existing tab bar being turned 90 degrees and put on the side of the screen. Which does not match the proposed or old design either.
Correct, Google AI was mistaken by sticking that word "Domestic" in there along with "USDA". Only 94.2 million cattle In the USA, which the maximum number of Bison was somewhere around 30 million. This matches the 3x to 4x increase that I expected. I am surprised that the USA has such a small portion of the world total however, but the 1.5 billion number was backed by multiple sources.
I have also heard that both Bison and grass-fed cattle emit less greenhouse gasses than most farmed cattle, not sure what the factor is.
Still, Slashdot doesn't have to play along with their weasel wording. For example, "ergonomic collars that deliver an electric pulse" - just say "shock collar". Don't help them whitewash what they're talking about.
In case anybody is taking this seriously (I think it is supposed to be a joke):
Domestic Cattle: ~1 billion (USDA) to 1.5 billion (FAO).
American Bison: Once 30-60 million (now much less)
If they had eliminated gas taxes and charged ALL car owners the same milage tax then it would have been fair. All the proposals certainly are punitive and are based on assumptions that the EV is driven far more than the majority of cars.
They don't "fly" or "sail", what spacecraft do is "fall" there. Except for the bit of time they use their engines.

Thank you for letting me waste your time.
You're confusing the importance of avoiding Kessler syndrome in LEO with the difficulty of causing Kessler syndrome. GEO debris can potentially remain there for millions of years before interactions between the gravitational pull of the Sun, Earth, and Moon sufficiently perturb it. LEO debris remains for weeks to months. You have to have many orders of magnitude more debris in LEO to trigger Kessler Syndrome, where the rate of collisions exceeds the rate of debris loss.
The fact that a LEO Kessler Syndrome would also be short is something that exists on top of that.
It's also worth nothing that not only are modern satellites not only vastly better at properly disposing of themselves than they were in the 1970s when Kessler Syndrome was proposed, but they're also vastly better at avoiding debris strikes. All of these factors are multiplicative together.
Lol, I was thinking of this instead
People forget that the primary concerns about Kessler Syndrome were about geosynchronous orbit, which used to be where all the most important satellites went (many of course still go there, but not the megaconstellations). It takes a long, long time for debris to leave GEO. But LEO is a very different beast.
They said it's internal rather than a collision, so probably a failed COPV would be my guess.
Yeah. In particular:
with fragments likely to fall to Earth over the next few weeks
LEO FTW. Kessler Syndrome is primarily a risk if you put too much stuff with too poor of an end-of-life disposal rate in GEO. End-of-life without proper disposal rates have declined exponentially since Kessler Syndrome was first proposed (manufacturers both understand the importance more, and do a better job, of decreasing the rate of failures before deorbit - in the past, sometimes there wasn't even attempts to dispose of a craft at end-of-life). And now we're increasingly putting stuff in LEO, where debris falls out of orbit relatively quickly. It's not impossible in LEO, esp. with higher LEO orbits - but it's much more difficult.
Or to put it another way: fragments can't build up to hit other things if they're gone after just a couple weeks.
And this trend is likely to continue - a lower percentage of premature failures, and decreasing altitudes / reentry times. Concerning ever-decreasing altitudes, we've already been doing this via use of ion engines to provide more reboost (with mission lifespans designed for only several years before running out of propellant, instead of decades like the giant GEO ones), but there's an increasing interest in "sky skimming" satellites that function in a way somewhat reminiscent of a ramjet - instead of krypton or xenon as the propellant for an ion engine, the sparse atmospheric air itself is the propellant, so the craft can in effect fly indefinitely until it fails, wherein it quite rapidly enters the denser atmosphere and burns up.
Yea I was wondering about this. I pretty clearly saw that some (all?) of the Fidelity funds that a 401K can invest in include bitcoins as part of the portfolio. So what exactly is new?
But electric cars are WOKE! Seems like a massive failure by Trump.
