A bit more about the latter. Beyond organophosphates, the main other alternative is pyrethroids. These are highly toxic to aquatic life, and they're contact poisons to pollinators just landing on the surface (some anti-insect clothing is soaked in pyrethrin for its effect). Also, neonicotinoids are often applied as seed coatings (which are taken up and spread through the plant), which primarily just affect the plant itself. Alternatives are commonly foliar sprays. This means drift to non-target impacts as well, such as in your shelterbelts, private gardens, neighbors' homes, etc. You also have to use far higher total pesticide quantities with foliar sprays instead of systematics, which not only drift, but also wash off, etc. Neonicotinoids can impact floral visitors, with adverse sublethal impacts but e.g. large pyrethroid sprayings can cause massive immediate fatal knockdown events of whole populations of pollinators.

Regrettable substitution is a real thing. We need to factor it in better. And that applies to nanoplastics as well.

So, when we say microplastics, we really mainly mean nanoplastics - the stuff made from, say, drinking hot liquids from low-melting-point plastic containers. And yeah, they very much look like a problem. The strongest evidence is for cardiovascular disease. The 2024 NEJM study for example found that for patients with above-threshold levels of nanoplastics in cartoid artery plaque were 4,5x more likely to suffer from a heart attack. Neurologically, they cross the brain-blood barrier (and quite quickly). A 2023 study found that they cause alpha-synuclein to misfold and clump together, a halmark of Parkinsons and various kinds of dementia. broadly, they're associated with oxidative stress, neuroinflammation, protein aggregation, and neurotransmitter alterations. Oxidative stress is due to cells struggling to break down nanoplastics in them. They're also associated with immunotoxicity, inflammatory bowel disease, and reproductive dysfunction, including elevating inflammatory markers, impairing sperm quality, and modulating the tumor microenvironment. With respect to reproduction, they're also associated with epigenetic dysregulation, which can lead to heritable changes.

And here's one of the things that get me - and let me briefly switch to a different topic before looping back. All over, there's a rush to ban polycarbonate due to concerns over a degradation product (bisphenol-A), because it's (very weakly) estrogenic. But typical effective estrogenic activity from typical levels of bisphenol-A are orders of magnitude lower than that of phytoestrogens in food and supplements; bisphenol-A is just too rare to exert much impact. Phytoestrogens have way better PR than bisphenol-A, and people spend money buying products specifically to consume more of them. Some arguments against bisphenol-A focus on what type of estrogenic activity it can promote (more proliferative activity), but that falls apart given that different phytoestrogens span the whole gamut of types of activation. Earlier research arguing for an association with estrogen-linked cancer seems to have fallen apart in more recent studies. It does seem associated with PCOS, but it's hard to describe it as a causal association, because PCOS is associated with all sorts of things, including diet (which could change the exposure rate vs. non-PCOS populations) and significant hormonal changes (which could change the clearance rate of bisphenol-A vs. non-PCOS populations). In short, bisphenol-A from polycarbonate is not without concern, but the concern level seems like it should be much lower than with nanoplastics.

Why bring this up? Because polycarbonate is a low-nanoplastic-emitting material. It is a quite resilient, heat tolerant plastic, and thus - being much further from its glass transition temperature - is not particularly prone to shedding nanoplastics. By contrast, its replacements - polyethylene, polypropylene, polyethylene terephthate, etc - are highly associated with nanoplastic release, particularly with hot liquids. So by banning polycarbonate, we increase our exposure to nanoplastics, which are much better associated with actual harms. And unlike bisphenol-A, which is rapidly eliminated from the body, nanoplastics persist. You can't get rid of them. If some big harm is discovered with bisphenol-A that suddenly makes the risk picture seem much bigger than with nanoplastics, we can then just stop using it, and any further harm is gone. But we can't do that with nanoplastics.

People seriously need to think more about substitution risks when banning products. The EU in particular is bad about not considering it. Like, banning neonicotinoids and causing their replacement by organophosphates, etc isn't exactly some giant win. Whether it's a benefit to pollinators at all is very much up in the air, while it's almost certain that the substitution is more harmful for mammals such as ourselves (neonicotinoids have very low mammalian toxicity, unlike e.g. organophosphates, which are closely related to nerve agents).

Everything needs to be branded or monetised.

It's why I want large commercial organisations as far away from my data, computers and workflow as possible.

I do not care about you, I don't want to be reminded you even exist, and I certainly don't want to give you money. Go away.

I want to turn on my computer, load up the browser of my choice, and that's it. I don't need to see a single brand, no "notifications", no messages of your choosing, nothing. My boot screen is a spinner. My desktop is a flat, blank, plain colour. I have my browser pinned as a single recognisable icon (doesn't even have the name).

That is what an OS should be. That is what most services should be. We shouldn't be spending our life subject to the whims of a corporation trying to wheedle money out of us or "foster brand engagement" or whatever nonsense they class it as.

The one good thing about hitting limits on CPU clock speed, memory shortages, etc. is that they might finally have to start actually making programmes vaguely efficient again.

There's also yet-another reason that I don't use Windows, and that's that everything seems to want an app running on startup to cache what it needs to to present these shitty web UIs with any semblance of performance, to do the most worthless things.

There are far too many programmes that just don't function correctly if you have a software firewall other than Windows Defender and you deny them web access, for instance. Windows Defender just lets it all through, but if you have a "ZoneAlarm-type" firewall, you see that EVERYTHING wants to talk-home or connect to a local web service and, when denied, it hangs up and falls over itself rather than deals with it gracefully.

Not what you want to see in critical services, for example.

Tell me how you're ever going to implement this on any open-source operating system ever?

Because people will just patch it out.

It's not like it's even a boot-time requirement (thus necessitating it being in the kernel/initrd, etc.). It's an account requirement. Which means that it can be patched out in no time at all.

As far as I know, not one single open-source OS has actually implemented this requirement (they put a field that would be useful for it into systemd, but nobody's actually using it).

While it is an enormous problem, possibly the most significant, we know how to shield against radiation, but it's going to take mass in the form of hydrogen-rich molecules like water or polyethylene (as examples). To solve that problem we are either going to have to make launches a lot cheaper, or figure out how to do it all in orbit.

It's at the edge of our technological capacity to produce such a spacecraft now, so the barrier is economic. That's a massive barrier, but in theory we definitely could, if we put a significant percentage of GDP of the wealthiest nations towards the project, produce a spacecraft that keep astronauts alive and relatively protected from ionizing radiation both on the journey and while on Mars.

As to your general assholery, I guess everyone has to have an outlet, though why Slashdot is a bit mysterious.

Assuming it's remotely true (and there's good reason for thinking it isn't), it still means the FBI director was negligent in their choice of personal email provider, that the email provider had incompetent security, and that the government's failure to either have an Internet Czar (the post exists) or to enforce high standards on Internet services are a threat to the security of the nation (since we already know malware can cross airgaps through negligence, the DoD has been hit that way a few times). The FBI director could have copied unknown quantities of malware onto government machines through lax standards, any of which could have delivered classified information over the Internet (we know this because it has also happened to the DoD).

In short, the existence of the hack is a minor concern relative to every single implication that hack has.

There's no such thing as technologically unable to comply.

If a nation state law enforcement insists, they will make you comply, and you and I will never hear about it.

A simple OS update with "If phone MAC == XXXXXXXXXX then send copy to FBI", targeted specifically at one phone, deployed only to that one phone, would go entirely unnoticed by the world.

And Official Secrets Act / equivalent, combined with a government-NDA and jail time for talking about it's very existence is literally routine. Has been since the days of black boxes in ISPs and them tapping Google's inter-datacentre links.

If someone like the FBI, NSA, MI5, GCHQ, etc. wants you to do something... you have literally zero choice in the matter. And talking about it will get you immediately jailed. And it really doesn't matter how big you are.

You think that Whatsapp end-to-end encryption is just going to make GCHQ etc. go "Oh well, nothing we can do?" No. If they need it, there'll be a guy knocking on your head office with a bunch of people, he'll only tell you why he's there in a closed meeting, you will comply, even if that means throwing everyone out of the datacentre and doing it yourself, and if anyone hears what he asked you to do, you will go to jail.

Been the same for decades. They just don't use it for ordinary crimes and petty stuff, mostly because of the resources they have to deploy to ensure that it stays quiet.
