For most manufacturers I agree, but Apple has the capability to disassemble and refurbish their devices in an automated fashion and incentivizes users to trade in their old equipment with discounts on new products. There is a lot less that gets sent to landfill as a result.
This looks like the holy grail of extension development, effectively a Python runtime HAL, it's wildly exciting. Getting anything to work optimally on PyPy and CPython more or less means writing it twice. CFFI overhead on CPython really sucks for anything where the runtime of the wrapped function does not eclipse the overhead of the binding. HPy looks like a fantastic approach.

Only complaint from a quick scan -- carrying over that horrid PyArg_Parse() API. It's huge, needs varargs, isn't type safe, repeatedly rebuilds strings to look them up in kwargs, and isn't even all that convenient to use. Also, if you haven't dealt with a SEGV due to PyArg_Parse() before, it means you probably have never tried to write an extension

PyPy will become about 1000x more practical if something like this ever makes it into Cython. That would make it easy to bring over huge swathes of existing extensions like lxml.
Interesting. I know Target in particular offers a 5% discount to users of their in-house debit card.

Even if it’s within the rules, presenting customers with surcharges for using credit cards (as opposed to discounts for other payment methods) would probably still alienate many of them.

“A role for…” [phrase]

A frequent phrase found in submitted and published papers; it often indicates that the authors have nothing to say about the topic of their paper. In its more emphatic form, “A role for…” usually indicates a struggle by the authors to take a side on an issue, after a lengthy attempt to be both non-committal and a supporting party to all sides, as often happens in “molecular and cellular” or “basic and translational” research.

“Reviewer” [noun]

A participant in the review of a grant, paper, or grant proposal. In spite of being in a poor position to assess the merits of a proposal, reviewer tends to demand that authors submit their data for statistical analysis and back their results with it, which the reviewer usually does not. Reviewer usually requires that the author cite his or her own work to prove that he or she is worth reviewing. It is also assumed that the reviewer can detect the slightest amount of bias in any paper, which the reviewer also assumes has not been corrected for."

“Rigor”

Something for scientists to aspire to, a state of mind that would not be required if scientists could be trusted to do their job.

“Science”

A complex web of data, opinions, lies, and errors, now considered the most important (because most expensive) technology in the modern society. To remind you of this, you will frequently see scientists and editors use the word, claim to do something for the sake of science, or see it used as an adjective.

“The topic of the paper”

A wide-ranging category of things or ideas that may not have been relevant when the paper was written, but which the authors believe the paper should be about. Often, the topic is too broad or a non-topic, but is occasionally useful in order to generate support for yet another set of related papers, conferences, seminars, webinars, and so forth, which in turn are used to generate more data for “new findings”, which, after they are manipulated enough, may end up being published and generating yet more data to support a “re-review” of the original paper or other things.

“Validation step”

Another name for a random setting of a parameter of a model, simulation, or algorithm.

“Writeup”

A form of scientific communication in which the author states the information he or she wanted the readers to extract from the paper while making it as difficult as possible for them to find it.

“Writer’s block”

A common affliction among students, arising from various causes, such as: their desire to sell their ideas for a profit, their inability to realize this desire, the fact that their ideas are not selling and will not be bought, and the delusion that most of the wealth and fame in the world would be theirs if they would spend enough years doing science.

> 'watching TV' today when TVs and monitors are common and cheap is different from 'watching TV' 20-30+ years ago, when TVs were more of a luxury good [..]

Source?

Today, people seem to spend a significant amount of money on purchasing an expensive (large) TV. They then spend even more money on subscription services for content to watch on their TV.

Rewind 30+ years (when I was young): TVs were small, and the number of channels was too. No-one paid per month for access to channels. You watched what was being broadcast live, or you drove to Blockbuster and rented a tape. I don't recall that being considered "luxury".

I'm just a systems software guy, I don't know anything more than anyone else on Donnefeld's true motivations. The old saying is where's smoke there's fire. If Salter had intellectual integrity he would have dug into Donnefeld's past, and asked pointed and direct questions about vulnerability disclosure and how he intends to work with or against people that compete with him in the future. All I know is what is obvious to anyone else who spends 15 minutes looking into things. When a reporter spends DAYS digging up details on Matt yet fails to mention anything about the governance and flamboyant history of WG (the NetBSD incident is a carbon copy minus the salacious clickbait of Matt), what the heck is actually going on here? I think Salter is just stupid rather than a fully aware actor in all this. Donnefeld appears to have some kind of fundamental personality flaw that facilitates using people to inflate his ego.. this became such a big deal because he compromised another FreeBSD developer who never fully took responsibility nor publicly rebuked being used by a narcissist.

Donnefeld was a nobody in the kernel development community, comes out of nowhere with a relatively simple tunneling protocol that is tightly bound to certain design and implementation decisions, and continually insists implementation is inseparable from the protocol. Noobs celebrate this. Pros look at this and wonder what happens when the governance fails for any reason, when the crypto becomes outdated, how it evolves. Pros celebrate independent implementation because it means a general solution has been achieved and stands a good chance of lasting beyond one person, one company, and one implementation.

It seems like the main company everyone would be buying if they were public is SpaceX. So, that leaves space launch companies that are being crushed by SpaceX, and other companies that can make other space-related products or otherwise profit from space exploration.

My impression is that we're getting really close to being able to launch substantial payloads to Mars relatively cheaply, but now that it's time to start packing we don't know what to send. There should be whole industries gearing up to manufacture space suits, rovers, habitats, habitat construction equipment, mining and earth-moving (or is the proper term Mars-moving?) equipment, giant Mars-suitable solar arrays, equipment to generate methane from solar power, water, and C02, and so on. Maybe all that's happening behind the scenes in a non-visible way, but still it seems like there's an opportunity there.

I couldn't help noticing that ARK's logo looks suspiciously like the logo for the Outer Planets Alliance from The Expanse. Too bad their ticker isn't BLTALWDA.
The best explanation I've heard described NFTs as "baseball cards about things other than baseball players". Of course, baseball cards are valuable because of the centralized authority which limits the supply and designates certain ones as "authentic". Anybody can go print a picture of a baseball card; what's valuable is the official Topps one.

Whereas NFTs kind of give individuals the ability to "print their own baseball cards". What this means is that an NFT's identity isn't really just the item itself, it's the item + the person/entity that "minted" it. Anybody can go create an NFT for your piece of art, but arguably only the "official" ones from you are (should be?) valuable.

WRT NFTs as a whole: as with nearly everything else on the blockchain, I think it would be better as a centralized service that "minted" these "cards" and skipped the crypto stuff entirely. In addition to getting rid of the environmental concerns, this central authority could vet each "verified artist/creator", making sure that each NFT actually does come from the right party and isn't being fabricated by someone else (this is a real problem right now; I follow Twitter artists who deleted all of their art posts for fear of someone turning them into NFTs without their consent). If security is a concern for such high-priced transactions, just... use really long passwords/keys to secure people's accounts/items. Maybe upon purchase you get a custom YubiKey that has a picture of the item, or something.

...of course, then you wouldn't have all the crypto-fanatics hyping it up and boosting prices to get the whole thing off the ground :P

I see a lot of misunderstandings in some comments : we are not talking here about desired RF emissions but about unwanted EMC emissions at harmonic frequencies which just happen to interfere with the regular 2.4 GHz devices.This has nothing to do with how much spectrum is allocated to wifi vs mobile vs whatever... Here it is only about EMC (and it is well known for years that USB is difficult with EMC and it requires a lot of care on the PCB design !). And USB3 is not the only product that leads to difficulties : there are for example a lot of debates (at least in Europe) now with regards to the impact of LEDs (which might surprise a lot of people). Another example are debates on Wireless Power Transfer (which are desired emissions but with very strong harmonics that affect sensitive radio services)

On the Commodore 64 the OS was a REPL and ? was shorthand for PRINT, therefore you could type `? 2+2` and you would get the result printed.

Can I ask why you chose Tailscale over the alternatives? I've been looking at that spectrum of products and Tailscale does look nice.

One thing I can't get over is that it's pricing is "per user". That makes sense our user-oriented VPNs (dev workstations, home machines, and phones), but doesn't feel like it's oriented towards server use. My end use case is probably 80% securing server connectivity across sites.

Alternatives I've looked at include: ZeroTier, Slack Nebula, OpenVPN Cloud, and PriTunl.

ATM, I'm using ZeroTier for my home use and quite happy with it. I had hopes of being able to deploy something for work as well, which is why I leaned towards ZeroTier. For home use, TailScale's pricing wasn't a concern.

Neural Networks can do it all after they emerge symbolic representations, a way to represent logic and mathematics.

A neural network that just "feels" that Fermat's Last Theorem is true, is much less intelligent than one that can produce the proof of it and present that to us, so we can trust that what it's saying is true.

If you can't do symbolic manipulation, you are not really intelligent, artificial or otherwise, I would say.

> I see light arrive from X at some time T1+t1

Except that your notion of T1+t1 is already going to be different from any other (non-stationary) observer's, yes?

> I do a little math to calculate how long it took the light to get there (t1)

Doesn't this assume that light has a fixed speed? We know already that this ain't necessarily the case, even in a vacuum; there are plenty of things - like sufficiently strong gravity wells - that can slow down light considerably. And in the context of situations involving warp drives and wormholes and other things bending spacetime willy-nilly, that further throws a wrench in attempting to figure out how long it took light to reach you.

> and now I know what T1 is

More like you have a vague idea of what T1 should be, assuming a flat spacetime. My point is that spacetime curvature can already throw this out the window, and that it therefore doesn't seem like we should be taking that estimated departure time as fact.

That is: if how an observer is perceiving something is indeed what actually dictates reality, then I don't see how causality can actually exist in the first place, because different observers can perceive the same events in different sequences based on their relative movement. If causality is to exist at all, even under normal conditions, then it seems like it needs to be possible for observers to be wrong, no?

So maybe I need to ask this even more specifically:

> The issue is that I can find a frame of reference where T2 < T1

Okay, which frame of reference would that be? Under what conditions? By what mechanisms that would apply to literally all cases of superluminal communication (even ones explicitly formulated to avoid things like relativistic relative speeds upon which thought experiments like the tachyonic antitelephone depend)?

Another sentence that I didn't understand. Sigh. I often think that I am just not smart enough to be in this field.

But, in any event, I found GEB inspiring. Thinking about these world-changing ideas by approaching them from different directions turned me on.

>Today, if 500 people in a room use T-Mobile phones, but Verizon owns all the spectrum, then nobody gets to use anything. This is stupid. Verizon should have access to a fraction of spectrum proportional to their users in an area. More users, more spectrum, and vice versa.

That would require a fairly radical departure from the infrastructure of the existing cellular networks, wouldn't it? Right now, each provider has a monopoly on a portion of the spectrum within a defined geographical area, and provides the base station and backhaul infrastructure to support their network.

It's not like "Verizon owns all the spectrum in a room"; it's that Verizon has better base station coverage of that room than T-Mobile does.

The providers compete on, amongst other things, coverage and network performance. Sharing spectrum would effectively require mutualization of base station infrastructure. You would effectively have a single monopoly with the networks operating as virtual operators. It's very far from clear that would be a good outcome, to me, at least.
I absolutely agree. It's just your typical pseudo-intellectualism rant here. It starts with a provocative declaration and then backed up with some explanation that is technically true, but doesn't offer any actual insights or value.

Apple could make at any time. It took me a few years, but I am now pretty damn good with my hot air reflow station and can reliably work with pretty much any SMD.

If someone (who of of course has given informed consent that I am not Apple and they have no responsibility for this repair) wants me to try and fix their device, what's the good reason for Apple not selling me a component?

Because it makes no sense if your goal is to make as much money as possible. You'd rather sell them something new or capture as much profit as possible by selling your repairs.

I'm an apple customer only because I consider them the least worst option for me at this time. Nobody is king forever, and the second there's a viable option for me, I'm out.

A newspaper or news website would source most of their journalism from Reuters or Associated Press, and then fluff it up to fit their editorial stance.

The same articles would seem longer in print because they're formatted in such narrow columns, wrapping around images. There's some thought that goes into the layout.

Of course, the internet breaks that particular illusion. And I'm sure that if a marketing department could do to their printed paper what they do to their website, design and readability be damned, they would jump at the chance.
