Your neighbors leave dead things on your stoop?

I would call the cops.

"It's a trap!"

ED: Last time I looked (when the tech was brand new) I couldn't find any studies on plants, but there apparently are now, and... yeah, it's what I expected. In fact, it's even worse than I expected: because all the energy is absorbed in such a short distance (the (living) epidermal layer), it does a lot more damage in that (critical) layer.

That said, apparently at lower doses you can still kill fungal pathogens without hurting the plants, and is much more effective at doing so, there is that.

I wonder if we should be exploring even shorter frequencies for plants. If you go shorter, bacteria are going to be able to escape harm, but you'll still be able to kill viruses and maybe still kill e.g. fungal condia.

Hmm. New thought (re: 222 / 233nm): as a pesticide.

Insect exoskeletons tend to be proportional to the insect's size. A big beetle's exoskeleton might be up to a couple hundred microns thick, while an aphid's only a several microns, and a spider mite's cuticle is just like 1-2 microns thick. And even with insects with exoskeletons too thick to kill, they typically moult, and after moulting, the new soft cuticle is initially far thinner. Also, with winged pets, the cuticle is often far thinner than on body regions (to keep them light and enable fast movement).

I bet far-UV would really do a number on small pests & winged pests. And... hmm... I guess that means we can go back away from the world of plants and back to the world of humans: surely it will kill skin mites, lice, etc... anything not hidden by clothes / hair / etc.

(And that's without fuel)

I went searching trying to figure out where you managed to find a 3241 lb Camry. Seems the 2020 ones were that light, but were non-hybrid, while the current ones are now all hybrid. Of course, it has an even more anemic performance of 7,6s 0-60, and is once again, still smaller than the 3.

To repeat, from the top: actual class competitors of the Model 3 are cars like: BMW 3-series (330i for the SR, 340i for the LR), Mercedes C-Class, Audi A4 & S4, Acura TLX, Infiniti Q50, Volvo S60, Jaguar XE, etc. And class competitors for the Model Y are cars like: BMW X3, Mercedes GLC, Audi Q5 & SQ5, Volkswagen Tiguan, Lexus NX, Acura RDX, Infiniti QX50.

Either compare apples to apples, or expect nobody to take you seriously. You might as well just say "BUT MY MOPED IS ONLY 200 POUNDS!!!".

Why on Earth are you comparing a SUV to a small sedan? Don't get me wrong, Model Y isn't exactly a GMC Yukon or anything, but it's much bigger than a Camry, with over double the cargo space (971L vs. 428L).The Camry has only 71% the cargo space of the Model 3. 7cm less front headroom / 5cm less rear headroom than the Y, and 4cm / 3cm less than the 3. And it's in an utterly different performance class. Are you, like, *trying* to be dishonest, or are you just this ignorant?

And even then, here's a stats table (US units for you). Tesla mass here and here and Camry here and here, for your disbelief.

Toyota Camry 2025 LE (FWD): 3,594 lbs, 6.9s 0-60
Toyota Camry 2025 XSE (AWD): 3,774 lbs, 6.8s 0-60

Tesla Model 3 2025 SR (RWD): 3,880 lbs, 4.6s 0-60
Tesla Model 3 2025 LR (AWD): 4,019 lbs, 4.2s 0-60
Tesla Model 3 2025 Performance (AWD): 4,080 lbs, 2.8s 0-60

Tesla Model Y 2025 LR (RWD): 4,235 lbs, 5.6s 0-60
Tesla Model Y 2025 LR (AWD): 4,392 lbs, 4.6s 0-60
Tesla Model Y 2025 Performance (AWD): 4,392 lbs, 3.5s 0-60

Explain to me how you think these numbers are somehow out of line with each other, given that even the 3 is larger than the Camry, and both are in an entirely different performance class?

Can't speak for them, but I've never gotten COVID and thus my risk for the much more severe, more common COVID-related myocarditis is zero.

"Processed" usually means smoked, cured, or other means of preservation. Cured meats commonly have nitrates or nitrites (carcinogenic) and tons of sodium. Smoked meats have carcinogenic PAHs and HCAs.

The quality level that you are talking about is not merely a matter of skill on the part of the developer, but also time. The formal methods used that produce that level of performance and perfection take a long time to apply, no matter how good one is.

The *primary* reason why most software doesn't perform at that level is this: time costs money. Software that is thrown together quickly, and as a result has bugs, will be available for purchase much sooner, and will cost far less (mainly because it cost far less to develop). People are willing to buy buggy software if it is going to save them a fortune.

For most applications, the level of perfection that you are talking about is simply not necessary. People don't need their software to be that perfect in order to do their jobs. Of course, too MANY bugs will be ruinous, so there is a sweet spot to find.

And that's my main point: there is a sweet spot, and for MOST (not all) software applications, it is nowhere near as high as what you are talking about. Therefore, there is no market for top quality software. Any business that tries to aim for that quality level will price themselves right out of the market and go bust before they even get their first product out the door.

So, don't blame the developers. They are simply doing what the market is paying them to do.

Life is competitive, and always has been. And nobody owes you a job.

Tech changes over time and everyone must adapt to it. That's going to put some people out of work. It's not a happy moment for them, but seriously, that's is how it has always been.

There is this nice theory that, by working together, we can all make sure everyone has enough without ever facing the horror of being put out of a job and needing to take unpleasant work to earn a living. Well, human nature doesn't really make this tenable, which is why it consistently fails when it is attempted.

For now, the essential survival strategy is the same as it has been for millions of years: adapt or die.

I am sorry if this news makes you unhappy. But that doesn't make me (or anyone else who understands this) a jackass. We are just adapting like everyone else.

You are talking nonsense. A Tesla Model Y battery is 1700 pounds, whereas a full gastank of a typical sedan is less than 150 pounds

SIGH.

First off, none of the battery packs in the 3/Y are 1700 pounds. The SR pack is 350kg / 772 lbs, while the LR pack is 480kg / 1058 lbs. This includes the charge cabling.

Secondly, unless you drive around in a vehicle that is nothing more than a gas tank or a battery pack, you're kind of forgetting a few things. Let's help you out.

ICE engines typically weigh 150-300kg (~330–660 lbs), and high-performance engines can exceed this. On top of this, the transmission usually adds another 70-115kg (150-250lbs). EV powertrains are light. An entire Model 3 drive unit, including gearbox, oil pump, filter, etc is ~80kg / ~175lbs. And actually this plays it down, because except in the performance Model 3 - which matches up against quite powerful / heavy ICE powertrains - they're software locked, so they're actually well oversized relative to what they're allowed to deliver.

ICE exhaust systems add ~25-45kg / ~50-100 lbs. Obviously absent in EVs.

ICE fuel systems (pumps, lines, etc) add another ~15-20 kg or so (maybe 30-50 lbs)

ICE vehicles, due to their inefficiency, require much larger radiators, coolant reservoirs, hoses, etc (again, another ~15-20kg extra over EVs).

The battery pack in an EV makes up the floor pan. Again, that cuts mass by a couple dozen kg.

The battery pack is a stiffening element, and eliminates the need for many dozens of kg of extra stiffening mass.

The needs of an engine block impose a lot more difficult design constraints on an ICE car, including a larger front end, a higher centre of gravity, a less compressible front end in an accident, etc. The need to compensate for these things also adds significant mass.

ICE vehicles have all accessories driven by the engine, and all electrics on low voltage (heavy wiring). EVs do it either with a DC-DC converter or direct HV, saving many kg again here. New EVs are also ditching the low-voltage battery altogether.

I could go on and on. The simple fact is, while EVs add (significant mass) in the form of one part, ICEs nickle and dime the car for mass all over the place. ICEs still win out mass-wise, but on a class-and-performance comparison, like-to-like, the mass differences just aren't that much (again, unless the designer is just bad at their job or doesn't care - *grumbles again in Hummer*).

(Also, re: serviscope_minor above: You don't compare vehicles by length; it's not a very useful metric. For size, you can compare by interior space specs - trunk / frunk volume, driver/front passenger head/leg/shoulder/hip room, rear passenger head/leg/shoulder/hip room. Length isn't a good proxy because it ignores packaging; a 1960 Chevy Corvette might be "long", but has very little interior space. Interior space and overall profile are often included as part of the category of "class" (for example, the Model 3 and BMW 3-series both have very similar interior space metrics and profiles). Also part of "class" is perceived / marketed luxury, though people differ over what counts as luxury, so it's not a very clear-cut metric. Performance is another axis, as higher performance cars tend to be heavier and/or have less interior space relative to their footprint (though EVs suffer a lot less on this than ICEs).

You can't get sunburned from far-UV like you can with normal UVC. It doesn't penetrate deep enough to reach living skin cells (e.g. the (dead) stratum corneum is 10-40 microns on most skin, up to hundreds on e.g. palms and soles) - in human tissue, 222nm penetrates only a few microns, with most of the energy deposited in the first micron; the deepest any degradation was seen in one study was 4,6 microns (for 233nm, it's 16,8 microns). As mentioned earlier, the only cells it can kill are the outermost layer of cells in the eye (corneal epithelium), but they're constantly being shed regardless (the entire corneal epithelium is 5-7 cells thick and has a ~1 week turnover, so on average just over 1 day per cell on the surface).

The comments about material degradation probably are also not true with far-UV. It's certainly ionizing, but again it doesn't penetrate deeply into surfaces . Paint is generally many dozens of microns thick (a typical two coats of interior paint is ~100 microns), while epoxy is typically millimeters or more, so you're only going to be affecting the extreme outermost surface. I doubt you could even tell.

Also, contrary to popular myth (and indeed, our pre-COVID medical understanding), most common communicable diseases (influenza, COVID, most cold viruses, etc) spread by direct airborne transmission, not fomites (surface transmission). So how well surfaces are cleaned has no bearing on this primary means of transmission. That's not that surfaces don't matter - said diseases still *can* be transmitted from fomites, and some other diseases (esp. fecal-oral route ones like norovirus) are still believed to be primarily transmitted via fomites.

Again, honestly, the only thing I would have concerns about are plants. Most plant cuticles are only like 0,1-1 micron thick. Xeriphytes (desert plants) can be thicker, though, like 1-20 microns, and are in general adapted to more UV exposure, so might be able to deal with it. But I'd think a plant with only a 0,1 micron thick cuticle and a 0,1-0,3 micron thick cell wall will get its leaves pretty badly burned by far-UV. I'd expect any epidermis and stomata exposed to the light to be almost entirely killed. But if you had a cactus or plant with really waxy leaves, it might be fine.

That we should be cool with them blowing through billions of our taxpayer dollars so that they can throw shit at a wall and see what sticks.

SpaceX has saved the US government an immense amount of money. What are you even talking about? Falcon 9 / Falcon Heavy is by far the cheapest launch system out there, and is also, FYI, the most reliable launch system out there. And it go that way by exactly the process above. And that process cost far less than NASA spends to develop its super-expensive launch systems.

Tesla has been at approximately mass parity with its closest class/performance competitors from BMW (with a full tank of petrol) since 2017 (the 330i vs. the SR, the 340i vs. the LR, etc). This "EVs are super-heavy thing" is a myth. I mean, sure, if you're terrible at your job you can design a really heavy EV (*grumbles in Hummer*). But usually, if the designers did their job right, the weight difference is small when matched up on class/performance competitors.

And beyond what others pointed out - that PM emissions are only a fraction of pollutants, and that they come from both brakes and tyres, and EVs have far lower brake emissions - it should also be pointed out that tyre PM tends to be mainly *coarse PM*, not fine PM. Both are harmful, but fine PM is significantly more harmful per amount produced. Brakes have a higher ratio of fine to coarse than tyres do, exhaust is higher still.

Cars also have air filters which capture PM. Generally well less than is produced, but I've seen a proof of concept where they amped up the air filtration so that the car was net negative. If you really wanted to, nothing is stopping you from mandating that. Still, economically your best bet is surely on taxing tyres (esp. studded ones) to incentivize people to choose durable ones and ones that don't wear down the roads, to limit hard accel / braking, etc.

Apple is not a completely closed ecosystem. You can use a Dell keyboard and a Logitech mouse with your Mac Mini, for example. There are legal battles being fought right now to make it even more open.

You have no basis whatsoever for your prediction "If Nintendo was open back in the day, they would not be the Nintendo we know now." That statement is based on nothing but pure imagination.

Open ecosystems provide consumers with more choices. That is an awesome benefit! I like the option to use Dell keyboards and Logitech mice with my Mac Mini. And I would like the option to use other-branded docks and/or converters with my Nintendo Switch 2 as well. It would sure be nice to be able to plug an XReal headset directly into a Nintendo Switch 2 for example. But thanks to this arbitrary limitation, I need a rat's nest of power cables and converters to get that to work.

Asking for this is not "crying," and there is nothing immature or entitled about it. Your penchant for insulting those who disagree with you, rather then presenting sound arguments, isn't going to win any hearts and minds.

There are clear consumer benefits to open ecosystems, so we are absolutely right to want them, and (if we choose) to use legislation to force them.

The "evil" here is blocking compatibility with third party components. Open systems are good for the economy and good for the end-user.

Whether the way Nintendo went about it is illegal isn't for me to say. I am not a lawyer and anyway I don't have all the facts. But I DO know that Nintendo is extremely successful in this market and charges a premium for their hardware and their games, so it feels injuriously greedy of them to block third party hardware as well.

They could have chosen to do right by their customers, but they took the low road.

Shame on you, Nintendo.
