In short, Java was invented for a reason, and while it has become a victim of legacy cruft as well, the underlying concept of truly portable apps, with a minimum of fuss to jump from platform to platform, still ought to be the preferable path. The problem is that that true platform neutrality/ambiguity pretty much kills Microsoft in all but a few niches, like gaming, but only because hardware vendors put less effort into drivers for other operating systems.

Yes, Office is still king, although I think that crown is beginning to slip, and it may end up being Excel, with its large list of features, that may last the longest. But it isn't 1990, or even 2000 anymore. Developers have multiple ways of developing portable applications, and while MS may (for the nth time) update or swap out its toolchains, the real question is will developers really care?

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).

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.

Firstly, I see you have this notion that martian rocks must all be igneous.

You're not talking about rock, you're talking about regolith.

Depending on where the regolith is sourced

Regolith is not "sourced", it's blown across the whole planet. It's not simply "whatever the underlying strata is made out of".

But, since we are playing 'name the ignorance' in this exchange, your attestation stat perchlorate is 0.5% liberatable oxygen says 'Say i'm ignorant of basic chemistry without saying i'm ignorant of basic chemistry, and am bad at reading too.' The 0.5% statistic comes from the publication at bottom, and is the proportion of the regolith that is perchlorates.

I am the one who mentioned that regolith is 0.5% perchlorates, not that "perchlorates are 0.5% oxygen". *facepalm*

"Saying we'll get oxygen from the 0,5-1% of a poison in martian regolith, rather than bulk ice or CO2, is..."

For God's sake, learn to fucking read.

Washing the regolith to remove the perchlorate is a requirement for *any* other use of that regolith

Which is why you shouldn't be celebrating its existence. It is a problematic contaminant, not a resource.

As you have rightly pointed out, the water ice on mars is more 'frozen mud'. Cleaning the melt is going to be a necessary first step to using it *regardless*. That means either vacuum distillation, thermal distillation, or reverse osmosis filtration. Again, NOT OPTIONAL. This is necessary equipment that you need to bring, regardless.

And this just to get water, the most basic of offworld resources. And all of that equipment (especially the mining hardware itself) requires maintenance and spare parts, which impose more dependencies. And the TRL for use on Mars is low regardless.

You've gone from talking up the ease of operating on Mars to talking it down, yet your self-righteousness hasn't shifted at all in the process.

RO filtration is the least energy intensive of these.

Except, it isn't. 0,5-1% perchlorates. RO typically removes 90-95% of perchlorates. So you're down to ~500ppm. Human safety levels** are in the low parts per billion. You're five orders of magnitude off. Yes, you can purify water that far - and the more perchlorates, the easier - but you're talking an over millionfold reduction. It is not at all trivial. You're talking first RO to get it down to levels where it won't hinder bacterial growth, then bioreactor bacterial remediation, then filtration, then RO, then ion exchange. This is not some little, simple system.

** Plants can tolerate much more perchlorates than humans, but they also bioaccumulate perchlorates of exposed to them, so you have to reduce the water to low ppb levels.

The end products are clean water and perchlorate contaminated mud, and clean mud, with contaminated water.

Viola! *eyeroll*

And your "plan" for dealing with waste perchlorate doesn't just magically produce pure O2 and NaCl in the real world. First off, molten sodium perchlorate, which is what it becomes before it decomposes, is an extremely corrosive oxidizer. Exactly what are you planning to make the furnace out of, platinum? Secondly, you never get perfect decomposition. Apart from residual perchlorates, you have residual sodium chlorate, which is also corrosive, and is a literal herbicide. And your gas stream will contain contaminant chloride and chlorine dioxide, which, news flash, you don't want to breathe.

There is no way on Earth anyone would ever prefer this to just conducting electrolysis on the water that you've already purified.

Neo and Android-based Chromebooks, and "good-enough" Office alternatives like Google Docs and I would argue even LibreOffice (I use it almost exclusively these days), mean Microsoft is suffering a differentiation crisis. They'll likely have the corporate lock for some time to come, though they've managed to fuck up Outlook so badly that I have to be wondering if the only thing really keeping the big guys locked in as Teams at this point.

MS's ability to leverage Windows as the platform is decaying, and the "bells and whistles" approach has managed to alienate a lot of users. People are at the point where they use Windows because they have to, but there's enough platform-agnostic functionality out there that the old lock-ins they relied on to keep Windows dominant are becoming more like prisons for their own development teams.

He's also a sleasebag who has been credibly accused of sexual assault by three women (and in general being a sex pest to many more). When a former friend (Jonny Robb) threatened to out him over it (it had been gnawing at him for a long time, and he was friends with some of the girls), Milton entrapped him (deliberately switching the topic to money, baiting him into asking for money to stay quiet, knowing that he was poor), then when he got Robb to ask for money, reported him into the police for extortion. Robb - his old friend - committed suicide after being released on bail. Milton rained largesse on local politicians, including the Attorney General's campaign. Milton was never investigated by the AG's office for sexual assault, while they arrested Robb immediately just on Milton's word.

I've talked with people online who knew Jonny Robb, and the universal answer was that he was the kindest person you'd ever meet. He had a hard life, struggled through overcoming depression and addiction, and had a lot of sympathy for others who were struggling as a result. I saw a podcast once where he was a guest, and I remember one of the topics was about a recent event where he was at a fast food restaurant, and there was a homeless lady, clearly mentally ill / schizophrenic, who was in general freaking out the guests and the staff, who didn't know what to do with her, and were probably minutes from calling the police. Robb orders for both himself and for her and sits down and eats with her, chats with her. She's having a great time, having not gotten attention like this in ages, starts joking that he's her boyfriend, etc. After they eat, he walks her out, much to the relief of the guests and staff, heads to a store and buys her a new sleeping bag and stuff. And she looks both simultaneously happy with her nice new stuff, but also terrified, and he suddenly realizes, oh shit, other homeless people are just going to steal this off her. And during the interview, he looked almost like he was going to cry when he said that.

Anyway, he's dead now.

I literally have a BA in horticulture. Regolith is NOT a good choice for hydroponics. Period. Stop trying to pretend it is one. Also, regolith has nothing to do with "shales", and it's not clay minerals either.

The closest thing to industrial hydroponics with it is using it to make rock wool (if the elemental composition is correct) - but you can also use, you know, rocks for that. Rock wool (basalt fibre) is basically air blown / centrifugally-flung lava (artificial Pele's hair) that has been spun. Rock wool actually *is* a common and effective cultivation medium for hydroponic (with the caveat that its reusability is limited, and on Earth we usually don't bother). The problem is that rock wool isn't just basalt. It's basalt + limestone/slag + binders (sprayed into the air to collect and bind the fibres) + other chemical treatments. You may be able to substitute anorthosite or similar for the limestone, but the binders aren't available, so you'd have to come up with new techniques to collect the fibres and make a "knitted" or "sintered" rock wool. As for other chemicals, the full composition of horticultural rock wool usually isn't disclosed (each manufacturer has their own optimal formula to be an ideal substrate), but you generally have to treat the fibres in various ways (as an example, for insulation, which has very different demands, they treat the rock wool with mineral oil)

The statement about bassalt fiber is not meant to be taken in a horticultural context.

"Tell me you've never been in a commercial-scale greenhouse without telling me you've never been in a commercial-scale greenhouse"

Those greenhouse tomatoes that you buy at a store out of season? They're probably grown like this. A TL/DR for you: you start out with rock wool (basalt fibre) plug trays to start your seedlings. You then put one seedling plug each into larger rectangular blocks of rock wool that have holes in the centre for them. When they're ready, you put them into a bagged slab of rock wool (usually a couple per bag), and that's what you produce from. You only maintain a small number of vines from each, regularly pruning off all internode suckers, as you have a fixed space between plants and a fixed amount of root volume so can't have them be expanding outwards (the fixed amount of root volume also means that you have to prune lower leaves to maintain balance). Your vines keep getting longer (and need to to produce more flower/fruit clusters), so when they get to the top of your wire, you incrementally slide them over until they're growing more and more horizontally. When you can no longer slide them over any more or they simply get too long, you remove the plants, toss the rock wool slabs, and start over.

And lastly, if your plan to deal with perchlorates from water is *literally splitting the water with electrolysis*, then you better stop celebrating the existence of this poison on Mars (one poison among many, it should be added - arsenic is higher than on Earth, chromium is commonly hexavalent, etc).

100%!

With the caveat that I'd not say lunar regolith is"like asbestos". Asbestos is unusually hazardous because it splits mainly along its long axis, so its fibres tend to get thinner and thinner over time (unlike, say, glass or carbon fibre, which tend to split transverse across the fibre). This turns asbestos into tiny needles that make it deep into the lungs, immune cells try to engulf them, fail and die, and then trigger an immune cascade in response. It's also not really the same as classic silicosis, either - on Earth we deal mainly with crystalline silica, but lunar regolith is mainly amorphous, which is less fibrogenic. It's less likely to cause long-term health issues and is less long-term stable (good), but the flip side to that is it's highly short-term irritating - not just from being fine and jagged, but also because (having not been exposed to moisture or the atmosphere) it's highly reactive.
