When on the road to hell, it's OK to be left behind.

“Wilt thou call again thy peoples, wilt thou craze anew thy Kings? “Lo! my lightnings pass before thee, and their whistling servant brings, “Ere the drowsy street hath stirred— “Every masked and midnight word, “And the nations break their fast upon these things.

“So I make a jest of Wonder, and a mock of Time and Space. “The roofless Seas an hostel, and the Earth a market-place, “Where the anxious traders know “Each is surety for his foe, “And none may thrive without his fellows’ grace.

“Now this is all my subtlety and this is all my wit, “God give thee good enlightenment, My Master in the Pit. “But behold all Earth is laid “In the Peace which I have made, “And behold I wait on thee to trouble it!”

The Peace of Dives Kipling, 1903

(As you know, there have been no major wars since then)

I too fear what governments will actually do in this area. But I think you may be underestimating the threat to personal agency.

Imagine you are trapped in a groundhog day like time loop - but you are not the person who remembers previous loops. "Z" is. He tries to convince you to do something, over and over and over, thousands or millions of times, refining his approach based on your reactions while you remember nothing. Are you really confident that your free will protects you from being taken advantage of in this situation?

Now imagine that instead of a time loop, Z has a million clones of you. He tries his persuasion on one of them at a time, refining it until it works reliably before using it on you. You are just as vulnerable.

Now suppose he has a billion people, not identical to you but drawn from the same distribution. He has a harder computational problem, mapping the high dimensional manifold of their responses to create a model of you sufficiently accurate to manipulate you. But with enough data he can approximate the results of the previous case without more than a tiny fraction of his experimentation being visible to you.

Any relationship where one party gets to surveil and monitor not only the other party, but millions or billions of like parties, has the potential to be a deeply abusive one. We should not tolerate such situations whether the surveilling party is a government or not.

It depends on whether people wake up to the threat before or after there is a robot army that can crush them, doesn't it? If humans are economically and militarily useless, it won't matter what they choose.

In the immortal words of Scott Alexander [1],

> I used to think that the alternative medicine people were overestimating how evil Big Pharma was. But now I know that’s not right.

> Now I know they’re underestimating it.

> If it were discovered tomorrow that potatoes cured cancer, then people wouldn’t “suppress” this “natural” remedy. Two years from now there would be an ultrapurified potato extract called POTAXOR™®© that was, on closer examination, physically and chemically identical to mashed potatoes. But these mashed potatoes would be mashed in a giant centrifuge by scientists with five Ph. Ds each. Any time someone got cancer, their doctor would prescribe POTAXOR™®© and charge $6,000 per dose, and the patient would get better, and the thought of just going out and eating a potato would never occur to anybody. Not to the doctor, who doesn’t want to sound like the idiot who tells her cancer patients to eat potatoes. Not to the FDA, who doesn’t know whether potatoes might be contaminated with lead or potato fungus or ketchup or God-knows-what. And certainly not to the patient. They would have to pay 60 cents for a potato at the supermarket, but if they have a good enough insurance the POTAXOR™®© is free!

> This system, bizarre as it is, is your guarantee against the pharmaceutical companies suppressing a promising new natural medication. Your insurance company pays $300 on fish oil, and in exchange you go to sleep at night secure that no one has discovered that potatoes cure cancer but decided to cover it up to protect their bottom line. Good deal? Given the current health system, it’s better than you had any right to expect.

Potatoes aren't on Schedule 1; that makes this situation suck a little more. But probably the alternative scenario is just the treatment remaining illegal forever.

I think this is reasonably precise. "Uniformly" means that all points within the unit circle are equally likely. You can sample this distribution by picking independent rectangular coordinates and rejecting points outside the unit circle. I'm sure you can sample it in polar space by using an appropriate nonuniform distribution for radius (because a uniform radius would not result in a uniform distribution over points in the unit circle). If you want to sample directly in some really weird parameterization I guess markov chain monte carlo methods are available.

The article currently says

> Three points are chosen independently and uniformly at random from the interior of a unit circle

Has it been edited in the last 15 minutes to address your objection or something?

I'm not sure Newton deserves shade for working on transmutation. The reason chemical reactions can't turn lead into gold was totally unknown at the time.

So if someone (actually, practically everyone) who runs an AI company says AI is dangerous, it's bullshit. If someone who is holding NVDA put options says it, they're talking their book. If someone whose job is threatened by AI says it, it's cope. If someone who doesn't use AI says it, it's fear of change. Is there someone in particular you want to hear it from, or are you completely immune to argument?

If AI makes humans economically irrelevant, nuclear deterrents may no longer be effective even if they remain mechanically intact. Would governments even try to keep their people and cities intact once they are useless?

For Newtonian gravity at least, the gravitational force everywhere outside a sphere or spherical shell is exactly the same as if it was a point mass (and everywhere inside a spherical shell it is zero). Not sure if it holds exactly for general relativity.

I can't help but think that numbering all the devices was the wrong idea from the beginning. You don't want to talk to devices, you want to talk to (and offer) services. You probably need something like an AS number to make global routing efficient, but 32 bits would be plenty for that. A packet could be (destination AS, stream ID, encrypted( payload )) and DNS would give you a capability (destination AS, stream ID, keys) for a service. You send a packet to that stream asking to open a connection and providing a capability to reply (with a capability for the specific stream). Your network up to the AS level should have an opportunity to augment the stream IDs in whatever way is convenient for its routing. No one reveals any topology information, network neutrality and a degree of privacy is guaranteed at the protocol level, only really serious multipeer networks need to assign addresses above layer 2, and I think it would be reasonably easy to come up with an edges first incentive compatible transition plan (which is where ipv6 went wrong).

(This is of course an incomplete and poorly thought out proposal, you don't need to dogpile me about that.)

I'm currently using recursive page tables for the OS I'm working on, but I'm probably going to change that. There are lots of different address spaces for different processes and (with IOMMU) devices, and it's nicer to be able to modify any of them rather than only the current one. I am leaning toward just assigning 2 MiB of memory to page tables at a time and keeping a mapping for these (I don't want to map all physical memory in the kernel for security reasons).

There's a history of finding really strong correlations between vitamin D levels and (many kinds of) health, and then disappointing results for RCTs of vitamin D supplementation. There are lots of possible explanations of this, but it seems like a plausible one is that there are some good things sunlight does for you other than produce vitamin D. So I'm a little nervous about everyone eliminating all sun exposure and then taking vitamin D geltabs to compensate, even though sunlight carries some risks. (But obviously too much ionizing radiation is also a problem, and it sounds like most users of tanning beds are getting a lot of intense exposure)

> PostgreSQL isn't "Generic SQL Database 47" it's the successor to Ingres (Post-Ingres-SQL)

How did they pass by "IngresSequel"?

I find these arguments unconvincing. But I do think that as an immortal it would be very difficult and painful to adapt to the changes in society and its values over time as an immortal. Eventually you must either join some isolated group like the Amish or else betray everything you love and believe in, over and over and over again, because whatever you think is important, the future will despise and forget it, while inventing new values incomprehensible to you now. Probably I am too opinionated to happily live even a normal human lifetime, but it's hard to imagine anyone so easygoing that a few thousand years of changes wouldn't leave them homeless.

If I were designing it today rather than in... 2008?, I would use the terms 'async' and 'await' because they are a lingua franca now. And for a modern audience that already knows what promises are it probably makes sense to start the explanation with that part. But the thing as a whole was intended to build lightweight asynchronously communicating sequential processes with private state that can be run locally or in a distributed way transparently, restarted on failure, etc. I don't think the choice of terms was obviously a crime at the time.

(Apologies, I guess, if your "agent" actually does this)

If you are building an application, you can and should know what your absolute time/power/cost budget is and evaluate the "speed" of operations against this absolute standard. It does not matter that some operation is 100x slower than it could be if it is still 10,000x faster than you need it to be.

But a lot of software engineering goes into building tools, libraries, frameworks, and systems, and even "application" code may be put to uses very distant from the originally envisioned one. And in these contexts, performance relative to the "speed of light" - the highest possible performance for a single operation - can be a very useful concept. Something "slow" that is 100x off the speed of light may be more than fast enough in some circumstances but a huge problem in others. Something "very fast" that is 1.01x the speed of light is very unlikely to be a big problem in any application. And this is true whether the speed of light for the operation in question is 1ns or 1min.

Apple could choose to give the users of their devices freedom to run whatever operating systems and programs they choose. Then they could truthfully say that there is no way for them to control what people do with their devices once they leave the Apple store. If you put yourself in control of such things because it is profitable, you ought to take responsibility for the consequences.

The paper defines this structure

    struct Strip {
        x: u16,
        y: u16,
        alpha_idx_fill_gap: u32,
    }

which looks like it is 64 bits (8 bytes) in size,

and then says

> Since a single strip has a memory footprint of 64 bytes and a single alpha value is stored as u8, the necessary storage amounts to around 259 ∗ 64 + 7296 ≈ 24KB

am I missing something, or is it actually 259*8 + 7296 ≈ 9KB?

The article [1] spends a lot of words questioning what the results of intelligence tests mean, and none questioning what the answer to "How happy are you?" survey questions mean.

[1] I would write "the author", but sadly these days you can't take the existence of an author for granted

The good dating apps just naturally made less money than the horribly destructive ones and got bought out and converted into destructive ones.

Yes. OkCupid basically solved dating, at least for people like me. It took me 2 dates to find the love of my life, and then I left the site (and all dating sites) forever. I paid them $0. Match Group, whose sites are designed to keep you single or in repeated failed relationships forever, made lots more money, bought them out, and ruined the site so they would stop shrinking the market.

It's a lot like how tech companies, data and advertisers have ruined news, friendship, phone, email, politics, ...

I think there must be typos in your K and S - the parentheses do not match. I get (with no warranty express or implied):

let K = A(A(A))(A(A(A))(A)(A)(A)(A)(A));

let S = A(A(A(A)(A(A)(A(A)))(A(A(A(A)(A(A)))))))(A)(A);

> Eager languages can be made lazy by wrapping arguments in lambdas with dummy arguments

So, something like this?

let A = x => y => z => () => x()(z())(y()(w=>z()));

The author is claiming that a sufficiently capable attacker can MITM the ACME protocol used to automatically renew certificates (and thus get a valid certificate issued for the victim domain with the attacker's private key). This is probably true as far as it goes, but certificate transparency logs make such attacks easy to detect, and browsers will not accept certificates that are not in the logs. Web sites that do not monitor CT logs probably are vulnerable to well resourced attacks of this kind, but I don't think there is a huge plague of them, maybe because attackers with the ability to MITM DNS requests for LE don't want to burn that capability on such easily detected attacks.

If you use AI to communicate with me, you won't get a reply from me. I have no further interest in communication with you.

The key thing that memory safety provides is local reasoning. You can look at some important piece of code and conclude that it does the right thing, even if there are a million other lines of code somewhere else. UB makes this impossible; no matter how carefully you review dont_launch_missiles() it might launch the missiles due to an integer overflow in totally unrelated code in the same process.

My first reaction to your objection was that the informal theory "heavier objects fall faster" inherently has one parameter per object (and that Galileo's objection more or less goes through against it) whereas you are discussing a two parameter theory. But on reflection I think you are right: "heaviness" could simply describe a derived quantity weight/mass.

They stopped before looking at the number of commits by person in the projects with multiple maintainers. I would guess that makes the picture even bleaker.
