Comment Re:When will sudo read email? (Score 1) 7

I can't comment on where sudo itself lives on the spectrum from aggressively solid implementation to really-dodgy-smell-around-the-edges; but it seems like its purpose is a fundamentally tricky problem even if its execution were impeccable.

The basic "user is authorized for root; but we'd prefer he be thinking and logged when he uses that authorization" is reasonably cogent use case; but it's more of a reminder than a security barrier. Then you get into the actually-interesting attempts at limited delegation and determine that you'd basically need a different userland for a lot of purposes: aside from the modest number of things(often with setuid already in place) built specifically to carefully do a very particular delegated function on your behalf and provide you with nothing else if they can help it; very little aside from garbage kiosk UIs or web or database-backed applications with user and permission structures mostly orthogonal to those of the underlying OS actually tries to constrain the user's use of the application(within whatever context that user is operating; generally having a privilege escalation is considered bad).

Half of what you run considers having an embedded shell to be a design feature; so including any of that on the sudoers list essentially means being able to chain arbitrary commands from that sudoers entry; and the other half doesn't outright intend to include a shell but would require some really brutal pruning, likely of important features, to prevent being able to chain a couple of interactions into having the ability to run whatever. And that is assuming that sudo itself is working entirely correctly.

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.

The race is already underway, and the EU is already way behind.

You can argue that AI is going to the "bottom" (whatever that means) and it doesn't matter, but that seems rather foolish. People betting trillions of their own money obviously see things differently. LLMs are improving dramatically, and there's way more to AI than just LLMs.

By forfeiting yet another technology, the EU will sit and watch as others get there first.

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?

Comment Why are we listening to this guy? (Score 1) 98

Why, exactly, are we listening to someone who passed through software engineering on his way into management claiming that software engineers(presumably now his direct reports) are the most spoiled profession and how it's just terrible that nobody is willing to spend several years working for peanuts to get experience(because the argument from race to the bottom is persuasive now?)

He then meanders over to the theory that if you are a real actually-good software engineer your job is clearly safe, because AI isn't set to replace you; ignoring the fact that entire teams, competent and all, get wiped out when the money sloshes a different way all the time; and 'AI' has seen some cataclysmic levels of frankly irrational money sloshing by some mixture of conmen, cultists, and the good old 'animal spirits' of that definitely rational market.

It's basically the same story about 'web developers' who learned how to knock together some HTML at a bootcamp somewhere, or 'IT' back when that was something where the money attracted some people who had no interest, warmed over and presented as novel; with a side helping of boundless(but notably vague) optimism about all the cool new AI-things that are being created that will need real engineers at some point.

Honestly, it's almost impressive how he manages to be so grating while being so vacuous.

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).

Ultimately, I agree with you.

The dems, crippled by an attachment to donors who hate what democratic voters want are strategically incapable of anything besides bare-minimum maintenance of the empire and its alliances. Their major accomplishments of the last 30 fucking years are all center-right patches on immense status quo problems: NAFTA, welfare reform, obamacare, *vague hand gesture* "infrastructure"

Trump, on the other hand, totally satisfies republican donors with two words "tax cuts", and can execute any pet right wing project of his no matter how catastrophic or cruel.

This dichotomy is why we're 20 years into the Chinese century now.
