"I'm not sure how compatible is it with the proposal in the article discussed here."

Right. It seems to me that both approaches make sense. Perhaps with some cleaver yet-to-be-determined math both ideas can finally be mated.

I've never been convinced that the æther doesn't exist. Sure, it's been long debunked in the luminiferous æther sense but as the article points out "...the aether hypothesis was abandoned, and to this day, the classical theory of electromagnetism does not provide us with a clear answer to the question in which medium electric and magnetic fields propagate in vacuum." It is this aspect of the abolition of the æther that has always worried me.

For starters, any new model of the æther would have to exhibit Lorentz-invariant properties. Then there's the matter of vacuum permittivity ε0 and vacuum permeability μ0 to consider as the speed of light/aka 'electromagnetism' is directly linked to these physical constants via the expression c = 1/(μ0 ε0)^0.5. If one constant were to change then so too would the others including α Sommerfeld's fine structure constant, RK the von Klitzing constant, and Z0 the vacuum (free space) impedance, etc., etc. (Anyway, one would expect them to change—not that we'd ever know as we'd likely not exist if they did). ;-)

But I digress a little. We know that ε0 and μ0 have actual non-zero values and cannot be equated out (as we sort of tried to do in the days when we expressed electromagnetism in cgs units). In essence, physical constants ε0 and μ0 are absolutely intrinsic to electromagnetism, and whilst I cannot prove the fact, it seems to me they would be just as intrinsic to any new definition of the æther. Moreover, similar reasoning makes me think that QFT, ZPE/Zero-point energy/quantum vacuum state, ε0 and μ0 are all inextricably linked to GR.

It seems to me that whilst matters such as whether the spacetime manifold is Ricci-flat, etc. are extremely important principally from the perspective that when properly dovetailed into any new theory they'll provide proof thereof—are secondary to the proposition (note, I'm not saying they're secondary aspects of physics, only that they're secondary to the initial proposition).

Moreover, an equally important question to ask is why the constants ε0 and μ0 have the values they do given the quantum vacuum state, etc. Of course, the same logic applies to both α and c. Finally, we base just about everything on c it being the fundamental immutable constant (despite the the perennial emphasis/importance of α ≈ 1/137). The question is, is it in fact so, or is it that underlying physics first determines ε0 and μ0 and thus these constants could be considered more fundamental to any new formulation of the æther than that of c, it being the consequential resultant of the properties of those constants. (Heresy I know, but it would seem to make sense to view c in this context if or when we end up with new definition for the æther.)

Over a longer time horizon, that same system that saved thousands of lives will kill millions more, and it will be done in total silence of anyone that dares to speak up and be a dissident.
If you say the rent is $100/sqft, then the tax break is for $100/sqft of unrealized rent.

If you rent at a reasonable (for the area) rent (say, $15/sqft), then you get the money, true, but it may not beat the tax break.

Passive house is a very high standard, and I do not think it is very practical to do it at large scale.

Aiming for something that can be net zero is probably more practical: building stringently up to a certain point, and then throw some PV panels to offset whatever expected energy use is remaining.

In my comment I meant to say that keeping software out of the wrong hands was ultimately not possible, and thought it would be better the give people more secure and more private means to communicate (something like pinephone, tor, matrix, etc).

Your first clause seems to agree with the first half of what I said (can't stop bad software), but then you said it was irrelevant. Maybe irrelevant to NSO, as long as they can get away with it? Or irrelvant to something else I said?

(I'm not opposed to going after NSO, also. Power to the people. But it seems many governments care about our data more than they care about our votes.)

I feel like the goal posts are moving with lightening speed.

Whenever I read a sentence like "The goal was never to eradicate COVID from being annoying—it was to eradicate it from being a killer." Those same experts, a year ago, were assuring us that COVID would never become endemic.

Same thing with vaccines. Yes, everyone should get vaccinated. Yes, we were given a ton of guidance that vaccines would stop the spread of COVID.

I feel like there are two camps:

1) Liberals, who are in control of the health establishment, who lie to get the behavior they want (starting with "no mask" advice, to now overselling vaccines, and rewriting history)

2) Conservatives, who ignore all science.

Liberal media emphasizes how we've always been at war with Eastasia, and liberals believe it. Conservatives point to inconsistencies and open lies, and use that to discount everything from medical, academic, and government establishments.
SF water has no PFAs [2].

Bay Area groundwater has lithium. San Jose groundwater had 2 ppb lithium in 1964 [5]. Santa Clara groundwater now has 5-10 ppb lithium [4].

SF has several aquifers. In 2017, SFPUC started using 4 mgd (million gallons per day) of groundwater from these aquifers [0]. SFPUC delivers 60 mgd to SF retail customers [1], so groundwater comprises 10% and the remaining 90% comes from Hetch Hetchy via pipeline [3].

I found no direct measurement of Lithium in Hetch Hetchy water. SF fills its reservoirs with Hetch Hetchy water [6]. These reservoirs had about 1 ppb of lithium in 1965 [5]. I expect Hetch Hetchy's lithium levels are unchanged.

TLDR: SF water has 1 ppb (1 ng/mL) lithium and no PFAs.

Ask HN: Any interest in a visual drag and drop K8s cluster builder?
I was talking with my friend about how much of a pain in the butt building k8s clusters are, and how we think working with helm charts and YAML is maybe not the greatest experience.

We brainstormed some things but the gist would be a visual drag and drop style builder, more akin to something like block based programming or like blueprints from the UNREAL game engine that handles building, deploying and monitoring. The thought would be to also generate the associated helm charts.

I built myself a custom calculator 5 years ago for my Android phone. I've reinstalled it once in that time frame, and that only after switching phones. Other than that, it's just there when I need it, with 0 maintenance in 5 years.

Were I to switch to an iPhone, I would have to either list my calculator on the app store (and pay the yearly developer fee) or have to remember every single week to "refresh" my app, otherwise it won't work the next time I need it.

Android has side loading. iOS has the bare minimum concession to allow developers to build something at all, and even that has unnecessary friction built in explicitly so that people don't try to use it to sideload.

THIS IS ME. I've never identified with X-gen or Millenials but THIS. YES!

I had a landline as a child but then around 12.....things started to get digital.

I remember hunting bears and rabbits in my 'computer processing' class in high school in Oregon trail. Which was a class that attempted to teach kids about the new technology that was coming out but wasn't great, because the teacher was a lady in her 60's and me and my friends were light years ahead of her.

The internet was all text for a while, then HTML came out and things started to get CRAZY!'

One friend made the newspaper because he was in high school making tons of money WRITING WEBSITES for people.

I had a beep beep boop modem and you had to pay for the internet by the MINUTE.

My buddys dad had a CAR PHONE because they were super rich.

I went from landline, to flip phone, to blackberry, to smart phone. Text and talk were limited to X number or X number of minutes.

It's pretty crazy being EXACTLY on the cusp of such a massive revolution and cultural shift.

If the blockchain is immutable how do you reverse transactions if there's no monopoly on force in order to force the transaction?

Say I have 1 ton of carbon captured, I am paid 1 coin and I "prove" that I captured 1 ton. Secretly, the mechanism of my capture is temporary and I realize not only the 1 ton, but an additional ton as it costed me energy to make this scheme work. What are you gonna do?

Another, more likely example is that I say I have 1 ton captured, EnergyCorp has Bob audit me, I tell Bob, you approve of my fraudulent capture notice and I'll give you 10% of the profits. Bob agrees, I am paid my 1 coin. I give Bob 0.1 of the coin. We both win. Later Bob is found to have participated in the conspiracy. What are you gonna do?

You, the smart reader are reading this and think - OK fine, we'll build a way to confirm capture without anyone else being involved. Well, I point to scenario 1. What're ya gonna do? The post basically assumes trusted auditors, which is fine, but why even do blockchain?

Blockchain cannot beat reality.

For what it's worth, both scenarios apply to traditional fiat, but at least in that scenario punitive damages apply and can be applied. I'm not sure how a tax or fine can or would be applied with any blockchain. It's also not even clear to me why blockchains are even necessary after skimming the OP.
with both copyrights and patents, fees should be just rise geometrically, yearly (but can be prepaid into the future). so for instance, the first year might be $1000, the second, $2000, and the 10th year, ~$1MM (a 2^n progression). by year 20, nearly every patent and copyright would be relinquished as the fee would be ~$1B. with those kinds of rates, even disney would have to innovate to stay large and relevant, rather than sitting on their laurels and collecting rents in perpetuity.
I agree, when my company moved from self hosted mattermost to slack, it was a definite productivity boost.
I don’t think there’s a sane answer to your question.

I think the real answer to your question is “financialization” and zero interest rate policy.

Banks don’t hold loans, they make fees for issuing them and sell them off as securities. There’s so much money chasing so little return that it’s very easy to sell anything that looks “conventional” even if the market really ought to be more skeptical. Since almost everyone involved makes their money off the transaction, they have so many incentives to keep the party going, even though it sure seems like it’s unsustainable and must eventually crumble.
Failing an audit by dodging it (how? blocking the roads with trucks? pointing a gun at the auditor's agent?) is a failure.

Same solution in PoS slashing for stakers who don't maintain required latency: too bad, we don't care why, it was your job to do it right, your stake is slashed. (See the NashX exploding equilibrium for another example of this: the buyer doesn't give a s—t whatever excuses the seller might come up with, because it's cheap talk; the seller makes things right, or their stake gets burned. Period.)

Except for when it does: there are a bunch of people who have repeatedly jackpotted state lotteries, they're usually described as 'reclusive mathematicians'. But that isn't what I'm talking about. I just checked the TX Lottery Commission's site and it looks like scratchoffs would run, worst case, a 30% return. I can't be bothered to calculate the upper bounds, but I'd expect it to be 40%-ish. That seems good to me, I especially like that you can skip the part where you have to drive out to some hotel to meet an undercover Secret Service agent pretending to be a Wells Fargo employee responding to your help wanted notice in Soldier of Fortune.
Those are two different definitions of technical. When you accuse someone of "getting technical", it has a very specific meaning: It means that they're overemphasizing the dictionary definition at the cost of more practical considerations. That's exactly what's happening here, by calling what Apple allows on iPhone "sideloading". Yes, technically, you are able to get an app on your phone without going through the app store. But without a paid developer account, the fact that you have to reinstall weekly is intentionally designed to make that impractical for actual use.
1. There is no such process, as already noted in OP.
2. Bribing or colluding with auditors only works until buyers or skeptics bring in further auditors, kicking off the forking game, as already noted in OP.

What do kernel subsystem interfaces usually look like? Is there a lot of shared ownership of objects with complex lifetimes (i.e. not just allocated on startup and never freed). Do APIs often require consumers to check invariants themselves? If so then there could be a lot of safety lost at the interface.

The best situations for using Rust modules from C are simple APIs that allow the complexity and danger to be strongly encapsulated.
The "dev kits" were freely sold to everyone and also bought by consumers, not just developers. Very different to sell-your-soul-NDA'd console devkits given out to select studios. "early adopter edition" would have been just as fitting.
