Most devices I have seen gets 2-3 years of updates, so you are looking at devices that are about a decade old at that point: exactly how long do you think it is fair that the manufacturer pays for updates to your phone?
What would the EM field of a photon look like if you moved along with the photon? Would the magnetic part disappear just like it disappears when you move along with a moving electron?
I think a friend of mine handled it well. He nurtured a trust based relationship with his children, trust was highly valued and it gave his children a lot of free way but he also set up clear boundaries.

They could do try do things behind his back, they had full window to do it but trust was so ingrained that I don't recall him ever finding out huge problems.

Which doesn't mean they wouldn't plead and beg and try to cajole to get something.

At some point he would explain the rationale behind a decision but in the the end when push came to shove if a "no" was spoken it was a final "no". He isn't forced to justify his decisions and it's accepted as is and I think somehow trust plays a part here. Because his children knows that it's not the thing to get (smartphone, movie time, etc.) that is at play but trust (edit_begin) ultimately trust and the only way to get that thing would be by breaking trust (edit_end). They have to keep their parent's trust and parents know they can only get that trust by actually trusting. So, it works out. YMMV.
I don’t think it’s about being easy, I think it’s about political will. Based on some of these comments from folks from Texas, and California, why aren’t you running for office to change these things?
Most international supply chains are unaffected by the pandemic. Looking at the UK in particular, Brexit had a bigger impact on supply chains than the pandemic, but even there (IIRC the UK is short of about 100k truck drivers and having problems even with some domestic supply chains) the international supply chains are mostly still in place.

This is likely one of those cases where something became widespread in the US before other countries, so places had the benefit of looking at the US implementation (or just improvements of technology over time) before installing their own.

I notice it with elevators in my own country - I rarely encounter an older, shaky, rattly elevator in my own country... because we took so long before they were as widespread.
Thanks for sharing this. I didn't expect to read that whole gist but I did and I'm glad I did. Happy for you.
$0.1 is the price of for carbon offsets. 1 Gallon gas = 20lbs CO2, and going rate for carbon offsets are $10/ton.

Due to how CA cap/trade works I can't directly figure out the marginal cost difference there, though it looks greater than the market offset rate (as you note these rates depend on caps).

Obviously I don't think that offset capture the total externality, but if a comparison is to be made some figure is needed. Even our 'green energy' figures don't capture their own substantial carbon footprint entirely.
I had a similar situation, where my 2015 Samsung S6 still seemed as good or better than most the mid to low range phones I saw in 2020, and open source support for the old phone through Lineage was spotty at best (one person would update new releases maybe). I eventually got a Samsung A51 which has about equivalent specs in most cases but has a slightly bigger screen.

It's sad how mostly fine hardware (just one replaceable component is bad) gets left behind, but it's not entirely limited to phones. A couple years back I had to replace the main board of my son's computer because the old gateway it was that came with windows 7 or 8 and that was updated to windows 10 stopped being supported in one of the fall or spring patch rollups. Windows 10 had worked on the computer for about a year, that mainboard wasn't supported in the update, so the update never applied cleanly. I understand dropping old system support eventually (even though the Linux kernel still supports everything, that doesn't always mean you can get really old systems to boot a modern distro without problem), but I would rather it wasn't mid-way through the OS lifetime. :/
Aesthetics, harmony, and simplicity are the guiding principles of mathematical conjecture. This piece is simply hypothesizing about a link while calling for further empirical research.

> Airports provide what they think customers want. Generally travelers want familiarity, which chain restaurants provide.

Indeed. For most people at an airport, they have a time boxed period to eat. The sitdown place with unknown ticket times does not work.
This is hopelessly biased and outdated. Acknowledging the potential dangers of poly-unsaturated fats is more or less mainstream nowadays, but these guidelines promote canola oil, and warn against eating butter. Diet recommendations should come with caveats that there is a low chance that this actually works for everybody. That this is Harvard's Public Health guideline does not bode well for the subset of the population that put their faith in research from top institutions.
Reading the article, this appears to be a speculative rehash of past theories claiming to unify electromagnetism and general relativity. The article ends on the note that empirical research is needed.

I did not see anything novel that would warrant further attention - did I miss something?
Aesthetics should have nothing to do with science. Aesthetics is the reason we thought the Earth was at the center of the universe and everything outside the orbit of the moon was made of perfect spheres. It's why the Soviet Union pushed Lamarckian biology instead of Darwinism.
> it makes me think they are not being the most objective evaluators of reality.

Generally in physics and in maths researchers tend to spend time evaluating solutions that are symmetrical or otherwise elegant. I suppose that does make us biased but we’re searching for answers in a very large space of possible answers. Beaming towards elegant solutions seems like a reasonable heuristic.
Same here, not looking back.
"finally recreated"? You know that this game has been implemented lots of times before? Here is a first google hit for me, seems pretty playable:

I don't see what's so special about this one.
I can second all these criticisms, as well as the advice below to upgrade the strap. I use the elite strap with the VRCover face pad and strap pad and it’s a massive improvement. I also find the VRWave strap pad makes it easy for me to run my link cable through the strap and behind my head which is also a comfort improvement in some games.

Electromagnetism is already understood to be a special case of the electroweak interaction, which is itself a component of the standard model. The paper mentions Maxwell's equations, but not these more general models.

It's still strictly better than no way at all!

Using something like OmegaSwitcher, it's easy to configure some DNS suffix like `.local.test` to be mapped to local Unix sockets. Not as easy as built-in support, but at least doable.
The annoying thing with Unix sockets is making sure to delete them and recreate them. IIRC, there’s no file system equivalent of SO_REUSEPORT.

America Is Getting Unvaccinated People All Wrong

Not only is the new stable there, cketti has been posting all of the betas leading up to this on F-Droid for quite awhile. :) You have to manually look once in awhile in the F-Droid client for newer beta builds to opt into using.
> Do you have any insight

Well, this is a working patch set, so, yes, though I have no direct involvement and haven't read all of it yet.

> I imagine it would have to use llvm-rustc,

Yes, it uses upstream rustc.

> is gccrs ready for the job?

Not yet. They're making great progress, but major chunks of the language are still missing. They'll get there.

Using upstream rustc isn't a blocker for new code implementing drivers, but it is a blocker for getting into older drivers, or the kernel. The blocker is platform support; or at least, the current largest blocker, and either rustc will gain it, or gccrs will be good enough to compile this codebase. We'll see :)

> Would it be emitting objects that gcc/ld would link against?

Yep, it emits output that looks like any C compiler's output, you link 'em together and you're good.

If you manage to compile the kernel with clang, in theory you can even get cross-language LTO; this is working in Firefox, but I'm not sure if anyone's tried it with the kernel yet or not.
No.
However, if you count that protein folding implies quantum effects and brain fuctionning is, as all other parts of life, essentially using proteins, then yes, any living cell is a quantum "computer" linked to a quantum "3D printer".

Mostly sand for the silicium. A little doping materials, phosphorous, arsenic. If you want to get fancy, cadmium, tellurium and selenium (but mostly that fad is over I think). Aluminium and copper for the frames and connectors, a bit of the usual plastics.

The big issue isn't resources, those are either present anyways or needed in very small quantities (dopants). The big problem is electricity for splitting up silicium oxide (sand) into usable silicium by electrolysis. You can do it in Germany, but then the power used will be mostly from lignite, so not very green most of the time.

Oh, and I forgot, glass for the cover. But again, mostly sand and heat.
Although a gauge field has multiple components, it transforms differently from tensors under a change of coordinates:

A -> O A O^{-1} - dO O^{-1} (O is the Jacobian matrix)

The second term is absent for tensors (such as the left side of their equation 4). It also vanishes on a flat spacetime where one only considers linear (Lorentz) coordinate transformations, but based on my cursory reading they don't seem to be making that assumption.
The earth is at the center of the visible universe.
Bezos made it very easy to shit on him for some of his behavior and his post-flight remarks, yes.

But I did enjoy the historical perspective in this post.

And still, I'm confused as to what this author arguing for, exactly. That space exploration should be nationalized, or else it's not morally good enough? That Bezos should make better, more noble use of his money? Or, that private space endeavors, however extravagant, somehow take away from what NASA is doing and the two cannot coexist well? I'm confused, what is the actual message here?
Modern low- to midrange phones certainly have more RAM and storage than your 2014 phone, which matters more than the raw benchmark scores.
What property tax breaks are you talking about?
In particles physics, they have a different explanation of electromagnetism that is also very natural, almost inevitable. https://en.wikipedia.org/wiki/Quantum_electrodynamics#Mathem... The explanation in particle physics is compatible with Quantum Mechanics and Special Relativity, but no one is sure about how to extend it to General Relativity. I'm not sure how compatible is it with the proposal in the article discussed here.

Non technical version (ELI25):

In quantum mechanics the wavefunction Ψ is has complex values. If you multiply everything in the universe by -1, nothing changes because all the physical results use ΨΨ* (where * is the complex conjugation). You can also multiply everything by i or -i. Moreover by any other complex number of modulo 1 because ΨΨ* does not change. (The technical term for this is U(1) global gauge symmetry.)

But you can be more ambitious and want to multiply each point of the universe by a different complex number of modulo 1. ΨΨ* does not change but the derivatives of Ψ change and they are also important. (When you use the same complex number everywhere, the derivatives is just a multiple of the original derivative. When you use a different number in each point, it changes.)

The only way to fix the problem with the derivative is to add a new field A. When you and multiply each point of the universe by a different complex number of modulo 1, then A changes in a simple to calculate but not obvious way. The change in A fix the problem with the derivatives of Ψ.

So now the equations of the universe with Ψ and A don't change when you make this change. (The technical term for this is U(1) local gauge symmetry.) When you write carefully how a universe like this look like, the new field A is electromagnetism. (Actually, you can get the electric field and magnetic field using the derivatives of A.)

This explanation looks more complicated than the explanation of the article, but the article is full of technical terms that you really don't want to know, like:

> Riemann curvature tensor is more than just Ricci curvature—electromagnetic fields stretch and bend the spacetime
Well good news, we've known that for a century as it follows from incorporating the electromagnetic stress energy tensor into the field equations
You're thinking like a technically enlightened person -- if not an engineer -- who prioritizes efficiency and control.

> I found that most low- and mid-range phones sold in 2021 have slower hardware with fewer features than my 2014-era flagship phone

Slower hardware doesn't mean equally outdated, and I honestly can't back up your claim with any data. A $30 Android Tracphone on Amazon has 1-2 orders of magnitude more storage, a 50% bigger battery, twice the cores, a bigger screen, better camera, and 4g (compared to the flagship phones in 2011).

The features you mention (wireless charging, screen type) have nothing to do with app or OS support.
Shell is not a US company and besides, relying on another country’s laws keep yourself from being exploited isn’t going to get you very far.
I am sure you get Lineage OS, or something like it to run great on an old phone, just as I am sure you installed Debian yourself.

Mostly when we are talking about phones getting upgrades or not getting upgrades any more it is about updates from the manufacturer, so I don't see where you are going.
>the Amiga emulated the fastest Mac FASTER than the fastest Mac

I remember when people would post this sort of thing on Usenet, for years after most people had given up on the platform.

By the time the A4000 came out (late 1992), there were Macs that also had 68040s and ran at higher clock speeds, so I don't think it was remotely possible to do what you say. How could a 25 MHz CPU emulate a 33MHz CPU faster than native under any circumstances?
They barely got Python 3.0 in before the code freeze. Whew! That was a close call.
I like the idea intuitively (the idea that infinite discrete photons are required to mediate continuous fields from a single electron over infinite distances never sat well with me), so are they claiming here that there is a relativity-version of Maxwell's Equations? Does it require an additional spatial dimension to account for charge, or does it operate it on the same spacetime as gravity? Regardless, if I'm understanding this nontechnical overview correctly, it's a large claim requiring a lot of work. Probably worth a Nobel Prize if it they actually pull it off.
The other thing is an unknown restaurant in an airport is an unknown quantity - it could be garbage or it could be really good, but if you're travelling and just want food to be done with, the chain restaurants provide predictable averageness.

Coincidentally, just three months ago I began drinking yerba mate[0] which is the tea or infusion in this game Yerba Mate Tycoon. I found it better than coffee in the afternoon, since it provides a slower onset and more sustained energizing effect with essentially no crash. I believe it’s due to it containing other compounds such as L-theanine apart from caffeine. Popular brands are Taragüi[1] and Canarias, and can be prepared in a standard French press almost like tea. Some even drink it in teabags[2].

For one, it's going to produce a metric where all the diagonal elements are positive (or zero) - different from the -+++ or +--- signature of "normal" spacetime.

The paper's calculation reminds me of Kaluza-Klein theory, which uses a similar construction as part of extending the metric from four dimensions to five:

"knowing" and "experiencing" may or may not be different things. I believe they are aspects of the same thing. But equating them does not solve the problem.

What does it mean "to know" as opposed to contain, or have access to information? A computer program, in one sense, "knows" what the current value of a variable is. But it has no awareness of its own knowing.

There is no doubt that we are creatures of stimuli that is computationally processed in the nervous system. However, there is an ontological difference between the the ability to process stimuli, and the experience of said stimuli. The presumption is that with a sufficiently complex system, the ability to experience stimuli will self-reflective awareness, i.e., consciousness will emerge. But that's a whole lot of hand-waving. What is the mechanism? None is offered. It is only assumed.

As others have noted, we cannot even agree on what the term "consciousness" means, and because of this, some would like to posit that consciousness does not actually exist, i.e., that it is illusory. The irony of this conjecture is that they are trying to convince self-aware beings that they are not self-aware. The intent to convince the other is itself a function of self-awareness. Intent cannot exist without self-awareness, and Persuasion of "the other" also cannot exist without self-awareness.

Denying a phenomenon does not make it go away. I could just as easily respond to the person making this argument that if, indeed, self-awareness is an illusion, then so is their argument. It is mere data, the product of a series of calculations leading to a linguistic expression that intends to communicate nothing. It is merely the output from an extremely complex set of interlocking algorithms.

Despite the difficulty of agreeing to a definition of consciousness, we each, to a person, know what it is because of our own experience. The reason all current attempts to explain consciousness are unsatisfactory is because these attempts contradict our common experience. In fact, every attempt so far denies experience itself. They are unsatisfactory because they are illogical, or because they do not provide any explanation at all, but merely presume that somehow the conclusion is achieved, despite the lack of any mechanism in the proposition that can bring us to that conclusion.

If we can even go so far as to agree: "Consciousness is a property of a being that is aware of its own existence, and is able to contemplate its own existence as an entity distinct from its environment," this does not make it any easier to explain how any computational model will arrive at such a property.

One does not have to be a theist to acknowledge this. Some of the best minds in consciousness research are atheists.
Those graphs only go back to 2000. Do we have older data?

Speaking of primary, elementary level perspective…

The school in question is where I went prior to its closing. After I graduated, white families decided to close a very new, nice school because they just didn’t want their kids among black students.

Even where there is money and great support, whites just don’t want to have any funding to go to black kids without their say-so.

It will never be solved. The hate is too deep. My old neighborhood had to resort to lengthy legal proceedings to get what they already paid for.

This is why affirmative action is necessary. The whites on the board closed the school because they wanted control.

Does anyone see how totally messed up this situation is and how it highlights the reality of deeply ingrained racism? Even middle class blacks who are not poverty level and not asking for free lunches can’t get a break. They bought and paid for a modern school, watched white people run away to other communities then forced the blacks to be bussed to the white school where the whites could allocate taxes their government controlled.
