Well, there's the token exchange RFC, which defines on-behalf-of/delegation and impersonation semantics.

https://datatracker.ietf.org/doc/html/rfc8693 has all the details, but here's an example:

   {
      "aud":"https://consumer.example.com",
      "iss":"https://issuer.example.com",
      "exp":1443904177,
      "nbf":1443904077,
      "sub":"user@example.com",
      "act":
      {
        "sub":"admin@example.com"
      }
   }
In this case, the user is user@example.com, but the actor is admin@example.com. (In the agentic case, the actor would be the AI agent.)

Is this kinda what you are looking for?

Japan fascinates me.

Growing up in the 1980s Japanese animation seemed to come out of a much larger cultural matrix: I was excited by Space Battleship Yamato and felt moe for the first time when I saw a pin-up of Lum from Urusei Yatsura and my intuitive understanding of that expanded universe turned out to be right: a written culture that started a bit before the year 1000 when Chinese scholars helped Japanese learn to write down their own legends and myths and brought along a wealth of Chinese and Indian literature and then another flowering when Japan opened up to the west and became the first culture outside the west to attempt to beat us at our own game.

It certainly looks as if it has negotiated a different configuration of the balance between individualism and community. In the US people seem to think you are a bad person if you want life to be cozy. On the other hand, I don't think they'd let me ride the bus as-a-fox in Japan. The police have a ludicrously high conviction rate and we don't know if it because if is they are too tough (torture suspects, in cahoots with the judge) or too lax (don't press charges unless they know if they can win)

Even though nonconformists don't seem to be accepted there, the culture industry proves that they must exist. Here on the other hand I increasingly feel frustrated that our vast inventory of fantasy and science fiction literature (Fred Pohl, Pohl Anderson, Piers Anthony, Alfred Bester, Vernor Vinge, ...) doesn't get visual adaptations but our gatekeeping-industrial complex has never seen a sequel it didn't like (Dune, Dune, Dune, Dune, ...) In Japan on the other hand somebody can make a web novel and then a light novel and then there is a manga and a terribly flawed anime that gets me back to the source material... and I'm hooked!

I don't know if I will ever go. I will never go to Akihabara, I've been there in so many video games that I have a vivid image in all my senses including a feel of how many steps it is up to the elevated platform across to the train station. It's probably all wrong but I wouldn't want to let the real thing ruin the Akiba in my mind.

Right. One thing I learned over the years is that you can support arbitrarily high level of tech debt and still be able to effectively maintain and enrich a successful software system, as long as you throw enough warm bodies at it.

The overhead will get absurd, you'll end up with 10x or more increase in engineers working on the system, all of them making slow progress while spending 90% time debugging, researching, or writing docs and holding meetings to work out this week's shared understanding of underlying domain semantics - but progress they will make, system will be kept running, and new features will be added.

If the system is valuable enough for the company, the economic math actually adds up. I've seen at least one such case personally - a system that survived decades and multiple attempts at redoing it from scratch, and keeps going strong, fueled by massive amount of people-hours spent on meetings.

Adding AI to the mix today mostly just shifts individual time balance towards more meetings (Amdahl's Law meets Parkinson's law). But ironically, the existence of such systems, and the points made in the article, actually reinforce the point of AI being key to, if not improving it, then at least keeping this going: it'll help shorten the time to re-establish consensus on current global semantics, and update code at scale to stay consistent.

> Except for in Korea, Vietnam, etc etc

I originally discussed "war between industrialised civilisations." "Korea, Vietnam, etc" were not that.

The World Wars drove home the argument that direct confrontation between industrialised socieities is a lose-lose proposition. Since WWII, what I think we've been experimenting with is whether industrialised civilisations can wage war by proxy and still come out ahead. ("Ahead" here measured in relative and absolute power and wealth.) The answer appears to be no–unless you can bog down another who was stupid enough to engage without a proxy. But I don't think it was obviously no until somewhere between the Iraq War and now.

It's because a compiler is supposed to be high-level to low-level; you already have a lower-level language to write in it, and not a higher-level one. Writing a C compiler in a higher-level language than C is going backwards.

E.g., Pascal compilers have traditionally been written in Pascal, hardly a language which conjures up a "low level" image.

How could the first Pascal compiler be compiled if it was written in Pascal, but a Pascal compiler didn't yet exist?

> I eat meat. And I'm highly, highly morally conflicted. I'll leave it at that to avoid sounding hypothetical—except to mention that the only logical reason I don't go vegetarian/vegan is the work and personal development that'd be required of me. (I'll take being called lazy over disingenuous any day, if we're ostensibly virtue signaling here.)

But that is precisely acting as a martyr.

You're "highly morally conflicted", which means you suffer inside. You could stop that suffering by either 1) going vegan, so you don't have to worry about it, or 2) deciding to continue eating meat and no longer worry about it. Right now, you're picking the strictly worse combination of continuing to eat meat and remaining conflicted indefinitely.

I'm starting to realize that internal moral conflicts are a lot like physical pain - it's an important signal from the body, and you should pay attention to it, but in the end, if you know you're not going to do anything about the underlying cause, then there's no point in continuing to suffer - you just make it go away with painkillers, and carry on living. This does not mean denying the problem - quite the opposite. Constant pain makes it hard to think rationally, and suppressing it puts you in a much better position to address its underlying cause.

They're defense contractors the same way IBM and Oracle are. Palantir has a huge USG business, but they're also widely used across the Fortune 500. From the coverage of Palantir online you'd think the company actually manufactured Palantirs, but they are in fact a database consultingware company; one person described them to me as "Oracle but with the benefit of the Web 2.0 technology stack".

People read things like this and a switch flips in their brain, that they're being told to be more charitable to Palantir, and that's not at all where I'm coming from. Rather: the attention paid to Palantir does a very effective job of running cover for Oracle, IBM, and Cisco.

Obviously, the ludicrous marketing/communications operation Palantir is running doesn't make any of this any simpler to reason about.

Austin prices absolutely exploded from about 2010 to 2022. A huge part of that was housing, and then just before the pandemic Austin became sort of a weird "meme stock" ("Elon Musk is moving there!", "Joe Rogan is moving there") where its popular vision far outstripped its actual reality. I remember travelling around 2018 or so and telling people I was from Austin, and nearly every time I got a "Oh cool, I've heard that's such an awesome city" in response, which was far different a response I'd get in like 2005 or so. I mean, I like Austin, but we also had 2 months straight of 105+ degree weather a few years ago...

Like the article states, when housing goes up everywhere, it means that even the lowest wage workers need to be paid a lot more to survive, so the reason basic sandwiches are so expensive there is that entry level pay is now about $25/hr.

The other issue you saw, homelessness, is especially concentrated in Austin. Austin is perhaps the most liberal city in deep red Texas, so homeless people flock to Austin because it has good services and a generally sympathetic populace, and some rural conservative locales have even been giving homeless people one way bus tickets to Austin.

I guess the good news is that Austin built a shit ton of housing since 2021-2022, so housing prices (including rentals) are falling faster in Austin than anywhere else in the US.

The libertarian argument for prediction markets is really beautiful.

It's just a pity it basically depends on all participants in the prediction market being basically unaware that they are participating in a prediction market, and being oblivious to the incentives to create the outcomes they are predicting by the very act of predicting it with money.

But other than that minor detail, that little minor catastrophic flaw in the foundation, it's a beautiful argument.

I think we can call it as a society. It's a failure. We can go back to banning them, not just for moral reasons, but just pragmatic ones. The theory doesn't work.

The ability for agentic LLMs to improve computational efficiency/speed is a highly impactful domain I wish was more tested than with benchmarks. From my experience Opus is still much better than GPT/Codex in this aspect, but given that OpenAI is getting material gains out of this type of performancemaxxing and they have an increasing incentive to continue doing so given cost/capacity issues, I wonder if OpenAI will continue optimizing for it.

"Do you want my number? It's inside this list:"

You might find it interesting to learn a bit about information theory. The entire purpose of your specific number is precisely to identify which number in that list is yours. Having the list of all possible numbers is irrelevant. Conceptually you can model that as everyone has that, all the time. But that's not enough to do anything with, because having that list entire list means you have zero information.

If you say "it starts with an 8", you've eliminated 90% of the possibilities. Now you have log2(10) bits of information, but you haven't nailed it down yet. For each additional number you give you give that many more bits until you nail it down.

This is a common misconception people have. I remember someone who claimed to have copyright all possible melodies by virtue of having printed them out and thus enumerated them. But that is meaningless, because the entire job of naming a specific melody is precisely the nailing down of which one you mean. Expanding the list of possibilities you might mean is actually a reduction in the amount of information, despite the superficial appearance of listing more numbers out, and when you expand the possibilities out to "all possible instances of the thing" you're actually at the minimum of information, not the maximum.

I've seen it marketed to help with sleep, anxiety (despite it causing anxiety in a lot of people), depression, any type of pain you can think of, nausea, hoarders of chronic conditions, etc.

I agree with the top comment - I think it's great that we're starting to deal rationally with cannabis, but we need to be realistic about. It can be beneficial but can also cause real harms, especially in children and young adults, and cannabis use disorder is a real thing.

Dynamic typing doesn't scale in large teams, it is however great in small projects, or if optional typing is supported, which took a long time to learn from languages like structured BASIC dialects.

It is no accident that all mainstream dynamic languages now have optional typing support, either in the language directly or via linters.

AI has been awful on Reddit.

I've acquired a sense for at least some of the bots. There's this set of bots that post a high-engagement post about once a day to an implausibly large range of subreddits, with implausible regularity. I can tell by the way I remove them and the way that the other subs are mostly not that most subs have not figured this out yet.

There is an obvious solution to that problem, which I haven't wanted to put out there, but I've become increasingly suspicious that it's already been figured out anyhow, which is to limit a specific user account to a specific "persona" with plausible interests and posting rates.

And that's where I think the race may well end, victory spammers. If there's a winning move against that in general I haven't figured it out.

I know reddit is concerned about this at the corporate level but I'm not sure they realize this is possibly their #1 threat, towering above all others. Not that I have any specific suggestions about what to do about it either. And it's years before the masses realize this and stop visiting, and by the time that happens all the social media companies are going to be in trouble for the same reason. You can see the leading edge here on HN but it's still only an almost negligible fraction of the total userbase of something like Reddit today. But that will change.

>> SMTP "“didn’t win because it was ‘better,’” he argued, but “just because it was easier to implement."

Yes - and this is actually really important! It's true of most of the important early internet technologies. It's the entire reason "internet" standards won over "telco" (in this case ITU) standards - the latter could only be deployed by big coordinated efforts, while internet standards let individual decentralized admins hook their sites together.

Did any of the ITU standards win? In the end, internet swallowed telephones and everything is now VOIP. I think the last of the X standards left is X509?

> Paid out like Spotify pays out artists.

So, mostly to fraudulent AI spam?

AI makes this problem worse in both directions. It makes it fantastically easy to produce ""content"". So if you're scraping content, or browsing content, you're going to run in to increasing amounts of AI. Micropayments makes this worse, because it's then a means of getting paid to produce spam. The problem comes when you want the ""content"" to be connected to real questions like "how does my dryer work" or "what is going to happen to oil availability six months from now".

AI trainers didn't pay book authors until forced to. $3,000 ended up being a pretty high value! But it was also a one-off. Everyone writing books from now on is going to have to deal with being free grist to the machine.

2010 MB C300 I bought in 2013 from a dealer after the lease expired, parked outside without a garage or cover since then (Virginia).

About 3 years ago a large branch (about 8" diameter) from an old overhanging tree fell right on the transparent sunroof cover and shattered it into a million pieces. After picking them out of the sunroof mechanism (which no longer worked after the impact) and the inside of the car, I covered the opening with several sheets of magnetized vinyl. Works great, never a drop of water inside since then and it's stayed in place without any attention. Temperature control inside the car at rest or while driving at highway speed is like it was before the damage.

Being old now I never go anywhere since I can get stuff delivered. About every 3 weeks I go out and the car starts right up, I drive a 5-mile loop to circulate the oil and then park it for another 3 weeks. Been doing this for years. I do get an oil change annually.

The phrasing of "gun rights" in the context that's really about gun responsibilities is a big part of the problem. And I say this from an unusual position; I'm a Brit who was taught to shoot at school (cadets). The urban gun control question is not so much about responsibility as about malice. There's not a huge number of people with murderous intent, but there are enough. And the resistance of rural America to the questions of either "do you actually need a gun?", "are you a responsible person?", and "no, you can't bring that into the city" result in thousands of deaths every year in the city. If they were willing to allow separate rules for different areas, this wouldn't be nearly as heated.

> If we were to uncap the size of the House of Representatives, and instead change so that each district contains 50k people (or close to it), we would have roughly 7k representatives in the House.

Nice and proportional, but a completely unwieldy number of representatives. 700 reps for 500k people each would be more manageable.

(of course, that means very little if (a) they're only from two parties and (b) all 7k districts are gerrymandered six ways from sunday)

What is wrong with all the good things in the world?

Oh, that takes me back to 1982.[1] This is very similar to what we did back then. The syntactical approach is almost identical. It's much more programmer-friendly than some other approaches. One of the problems with proof of correctness is that the people doing it tend to fall in love with the formalism, and it all becomes too abstract and hard. This project didn't do that.

It's not clear what they do when they need to prove something beyond what an SMT solver can do. That's supposed to be covered in section 11.4, "forall and exists: writing and using triggers, inline functions". What they call a "trigger" is apparently a theorem proved by some more powerful system. (Or just assumed as an axiom. That's cheating, and it will come back to bite you.)

That's the right approach - use an SMT solver for the easy stuff, which should be 90-95% of the proofs. Then use something else for the hard stuff. We used the Boyer-Moore prover, a predecessor to the ACL system. Others have used proof-checkers, and Lean. There's recent interest in using LLMs to drive something like Lean; the LLMs make mistakes but the proof checker catches them. Looks like they haven't gotten to this part yet.

The way to partition the problem is to use two "assert" statements in succession. An assert statement is a proof goal before the assert, and is assumed true after the assert. So when you hit something hard, you try to bracket it with

    assert(a);
    assert(b);
and get everything to verify with the SAT solver except

    a implies b
Now you have a self-contained expression to prove by some external means. Often you can prove such statements in a generic form, and reuse the proofs.

There should be object invariants, except that Rust doesn't have objects. It does have structs with associated functions and encapsulation. You need some way to express that structs with internal state are consistent before and after being called. C++ has about the right amount of hiding ("abstraction") for this, with public and private fields and functions for objects. Rust's idea of "private" means "same module", not "same struct". So invariants would apply to a module. Then you have to be very organized about when control enters and leaves the module. Like not calling pub functions from inside the module, because the module invariants may not be valid at internal entry to a pub function.

The extensional equality thing is interesting. It needs more description. The basic problem is this: for some types, such as sets, hash tables, and such, objects are supposed to be considered equal if you can't tell from the outside that they're different internally. Formally, the type must have the property

    for all functions f where x is an element of T, 
        x == y implies f(x) == f(y)
That has to be proven for all functions which accept T. Then you can treat type values as equal even if their internal representation is different. Such types can't have any access functions or pub variables which allow you to examine the internal state. For example, if you convert a set to a vector, it has to be sorted, so that you can't tell what the internal order was.

Nice work. Keep plugging.

From an illustration in the middle of the piece:

"The Stack":

Space: SpaceX, Blue Origin, Maxar, Voyager

Cloud: Palantir, IBM, Cisco, Meta, AWS, Microsoft

Surface: Data Centers, Urban Surveillance, Mobile Fortify, Axon

Energy: The Nuclear Co, Valar Atomics, Oklo, General Matter, Helion

Finance: Paypal, Coinbase, Ramp, Stripe, Erebor, Ripple

---

This doesn't make any sense at all. Many of the categories aren't even internally consistent, and the space->cloud->surface->energy->finance "stack" is incoherent.

I should like this, because one of my longstanding hangups is people hyperfixating on Palantir (the company), which is a database consultingware company and a JV version of Oracle in all the senses we care about --- civil tech punditry has an awful habit of focusing on these lurid instances when they're really just banal examples of something tech giant companies do generally, which has the effect of letting companies like Oracle and Cisco (both of whom have demons resumes) off the hook.

But if the author can't lay out a reasonable map of the industry and the forces acting on it, I have trouble taking the rest of it seriously.
