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.

Where exactly does supporting 3 people on $133k/year count as 'upper middle class'? You could be doing a lot worse, and many are; but that's not just tons of money in a HCOL area; and that's also lower than twice the median salary for full time employees with bachelor's degrees; so you are calling either a single income household doing a bit better than median or a dual income one doing worse 'upper middle class'; which seems pretty ambitious.

It's hard to train a cow to keep its cellphone charged; so you can see why you need something to keep their tracking collars topped up.

Realistically, the status quo has arguably outrun the dystopia there. Your phone already does far more than anything you could get into the power envelope of a bracelet or embedded chip implant, and if for some reason you've raised enough eyebrows that you'd be hauled in for an RFID read DNA is a pretty indelible identifier.

It's not 100% ironclad; but penetration is broad enough that you've basically got the majority carrying highly fingerprintable RF beacons and the minority standing out for their relative radio silence and attempts to deal in cash. Expensive and uncomfortable ankle trackers are good business and feel nice and punitive, just to remind the wrong sort of people we aren't happy with them; but you don't really need to impose a surveillance society when it will build itself for you.

My (admittedly anecdotal from the totally unscientific sample of random stuff I've had reason to work on) impression is that some 'shared' BMC ports had oddities related to network controller sideband interface speeds, since NC-SI is what the BMC is depending on if the NIC is on someone else's PCIe root. It's not like the BMC actually needs a faster link for much(normal management traffic probably doesn't fill 10mb and mounting virtual media may be literally once-in-a-lifetime) so the actual speed of the NC-SI interface was not a burning priority; but it left things up to the NIC whether it would support remaining at gigabit speeds and just quietly slipping the trickle of shared traffic in(presumably slightly more complex; but seems to be what the newer ones do) or if it would knock the link rate down visibly to simplify the case.

You see little echoes of similar behavior elsewhere. The intel desktop and laptop NICs that support 'vPRO' will be GB or 2.5GB when the system is on; but quietly drop back to 10 or 10/100 when it is off and it's just the management engine listening. Some enterprise vendor USB docks do similar things; looks like a normal USB NIC when the OS is up; but drops to a lower speed and operates quietly over, I think, some sort of oddball vendor-defined messages if one of their systems is plugged in but off.

I assume that, as an exercise, getting 5 simultaneous introductions working makes for a better paper; but is there a reason why you would want that in practice? Especially if there is any wobble in the ratios either randomly, across generations, or in the presence of certain environmental conditions that tweak the plant's metabolism one way or another that sounds like it would be a real pain in the ass to have to re-balance (and, if different patients are deemed to need different combinations even a perfectly stable plant is going to need re-balancing of the outputs) vs. very specifically going for a specific target output per-plant(or e. coli or yeast or whatever is easiest to bioreactor) and then just mixing to taste after purification. Is there some advantage I'm not seeing?

I realize that there are cases where some plant-sourced pharmacological effect looks like it is actually driven not by the identified 'active ingredient'; but by dozens or hundreds of assorted things, and in that case you just have to live with the complexity if you get better results with that than with purified isolates; but if you are deliberately engineering for very specific outputs why a mix of 5?

Isolate should be capitalized as Cloudflareâ Isolate©. They're probably running out of synonyms for Sandbox, Container, Jail, Cage, Cell, Vault, Pod, etc... And has the side effect of also being an homage to oldschool Science Fiction (Isaac Asimov The Foundation which probably has the word "Isolate" as a noun used more per page than any non-scientific book in history).

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.

Immunology, presumably.

The only donor bodies that aren't going to treat the transplant as an act of war are clones or heavily immunosuppressed; and it's probably more plausible to assume that you'll be able to clone a human like a sheep than assume that you'll be making some fundamental breakthroughs in immunology to deal more elegantly with unmatched hosts.

I can see the utility of having spare organs in certain emergencies; but how much life extension would you actually get even if the sort of neurosurgery involved in removing a brain and reattaching it to a new host's spinal cord were viable? Is the theory that the assorted ghastly flavors of neurodegeneration are actually to be blamed on older organs and everything will be fine; or is this just a very expensive way to ensure that you skip the various ways peripheral organs can kill you and are assured to be the spryest patient in the dementia ward?

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.
