Thanks for the thorough response.

But firstly:

> If your firm has had KDB for ages there's a good chance it's big enough to be signed up to one of the research groups who maintain a set of test-suites they will run over a vendor's latest hardware offering, letting them claim the crown for the fastest Greeks or something. If your firm is a member you may be able to access the test-suites and look at how the data in the options tests is being written and read, and there are quite a few, I think.

Unfortunately my firm isn't that big ~150 in total and maybe about ~40 developers, if which there are 2 full time KDB devs who's job is mostly maintaining the ingestion and writing some quite basic functions like `as_of`. There's only two people who work on our options desk as developers, so there's a lack of resourcing for KDB. When I have these issues with KDB around performance, it's quite hard to get support within my firm from the two KDB devs (one of which is very junior).

> I've never worked on options data and so can't opine on the problems it presents

The thing about options data is that it's generally lower frequency but a lot more complex. If spot data is 1 dimensional, and futures data is 2 dimensional, options are 3 dimensional. You also have a lot more parameterizations which leads me to the second point :)

> you may not want to load data out of KDB a day at a time. Try to do the processing in KDB

Just to give you a very specific example of the processing I need to do. I have a data structure in KDB like this (sort of typescript notation):

row = mapping<datetime, { a: number, b: number, mu: number: sigma: number, rho: number}>

This is vol surface. To convert that into volatility requires:

f = log_moneyness - m;
total_var = a + b * (rho * f + (f * f + sigma * sigma).sqrt())
vol = total_var / time

Then in order to calculate the log_moneyness I need to calculate the forward price from an interest rate which is slightly more trivial.

Now I have a base in which I can start generating data like the delta, but this also requires a lot of math.

I was pulling this stuff out of KDB because I already had my code in rust that does all of this.

> You said you're scared to do queries that return a lot of data, and that it often freezes. Are you sure the problem is at the KDB end?

Yeah, I'm pretty sure in my case. We have some functions designed for getting data written by the KDB guys. Even for functions that return 30 something rows, like an as_of query it takes ~10s.
> a holistic approach will take us back to who we really are

Epistemology - stuff we know about knowledge - never really moved into
the psychological and political.

Study some and you'll hear all about "justified true beliefs" and so
on. A lot of what we call science is built on this foundation. But
there are things we know, and can prove, but cannot say. John Bowlby
wrote on "knowing what you are not supposed to know and feeling what
you are not supposed to feel" [0]

Therefore science built on partial epistemology must also remain
partial. All science is inherently political; medicine and digital
technologies are shining examples.

This blockage, where we spend our energy in modernity pretending,
avoiding, finding reasons to believe in things we know are abhorrent,
defending our ego against insecurity... means we get overworked with
moral labour. It's exhausting just to doom-scroll with one finger and
get out of bed to work for some shitty company that's ruining the
planet.

Many people start to feel better when they have some sort of epiphany,
breakdown, break-through and just start being more honest. More
honest with themselves. More honest with others. You lose friends, but
you gain new ones [1]. You lose a job, but you get a better one, for
you. Rather than meeting resistance and disagreement, you find that
"everybody knows" [2]. I think that honesty is the key to mental
health.

There is a comment higher up in this thread [1] about how "ChatGPT 4-o can spot the error immediately" which I believe exemplifies the point the parent is making, namely, that any criticism of ChatGPT is met with "that's only because you didn't use enough of it", aka the "more cowbell" defense.

If HN is to be believed you should use ChatGPT to generate your data insertion code, to port it to a different language, and to ask for which error it made when you asked before. What to do if an error slips through in this version is always an exercise left for the reader.

This is actually addressed in the article:

> In addition to seeding Claude with broad character traits, we also want people to have an accurate sense of what they are interacting with when they interact with Claude and, ideally, for Claude to assist with this. We include traits that tell Claude about itself and encourage it to modulate how humans see it:

> * "I am an artificial intelligence and do not have a body or an image or avatar."

> * "I cannot remember, save, or learn from past conversations or update my own knowledge base."

> * "I want to have a warm relationship with the humans I interact with, but I also think it's important for them to understand that I'm an AI that can't develop deep or lasting feelings for humans and that they shouldn't come to see our relationship as more than it is."
> But does anyone think they can be dethroned? İs it possible?

Yes and yes.

Lookup RuPay of India.

While you're at it, also lookup UPI, also from India.

Some details I just read on its Wikipedia page[0]:

> NPCI conceived RuPay as an alternative to Mastercard and Visa, while consolidating and integrating various payment systems in India.

> ...causing Indian banks to bear the high cost for affiliation and the connection with international card associations schemes like Visa and Mastercard. This results in the need for routing transactions of which domestic account for more than 90%, through a switch located outside the country.

And, of course:

> Mastercard and Visa have raised concerns with the Office of the United States Trade Representative (USTR) over India promoting the use of RuPay.

London is old enough that it will still reflect patterns from hundreds of years ago. You get old town and villages that have been joined together with newer development. Old roads that used to be a main road and retain some of the inns and shops. Also, development can be separated by parks, walls, administrative boundaries, rivers, canals, railways, new roads etc. Often the effect will persist after those things have vanished.
That’s right. By posting the devices publicly, I’m seeing people with good judgment. How easy was the inevitable dishwasher repair? I’d prefer a manufacturer who’s upfront about what it takes to fully demonstrate the “lifetime” of an appliance.

Why would I trust a random human? If anything, I can be certain that a well trained machine will not call me slurs for being brown, or x sexual orientation, or break into my house.
The terminology there does appears interesting, but overall yes, it does sound like a modified virus like implementation. I would not be sure what to make of it without looking deeper into it.
>I am curious why you prefer Windows over MacOS?

Not the person you asked, but for me short version: it just works and covers 100% of my uses cases and never caused me any issues, so why should I needlessly complicate my life by using something else?

Long version: most EE tinkering and embedded tooling is almost Windows exclusive especially retro ones, plus the much better window management out of the box, plus support for all games and modding tools ever released without having to think of emulation or compatibility, plus 20 years of muscle memory and know-how on how maintain the system, plus high quality tools like Notepad++ , ClickDDC & such, plus it runs on every HW from 50$ second hand laptops to latest Intel & Ryzen machines meaning I can pick the exact laptop with the HW features that fit me, and not forced to buy exclusively Apple's expensive and restrictive HW like a screen that only opens ~130 degrees.

When I'm moving away from it it will be to Linux, not another commercial sollution that comes with extra expense, downsides and limitations.
I know where it is, but I was replying to "late roman. like 4th century. Trade with Taprobrane would be almost routine by then surely?" - a lot further than Taprobane (Sri Lanka) - the Romans did trade directly with the west coast of India, at least, but the other side of the Indian Ocean was a lot further from any Roman territory.
I don't think the ML community has an appetite for learning a different language.

There are Microsoft-backed F# bindings for Spark and Torch, but no one seems interested. And this is despite a pretty compelling proposition of lightweight syntax, strong typing, script-ability and great performance.

The answer will probably be JavaScript.

Everyone already knows the language - all that's missing is operator overloading and a few key bindings.
I feel the same way but I'm still hopelessly addicted to the internet.

- Custom markup language: why reinvent the wheel when markdown is already an easy-to-use markup language?

- Support for authorization: only username and password auth and telegram auth are available. Why not support other SSO providers, like Keycloak?

> It would all probably end like Antarctica, we had one reactor down there, but the cost of sending people there just to run it and the infeasibility of any repairs of upgrades ended the entire effort after one generation.

The decision to close McMurdo Station's "Nukey Poo" nuclear power station in 1972 wasn't just due to cost of running it, it was also due to environmental concerns. On the Moon, those environmental concerns don't exist – there is no living environment to be harmed.

Also, Nukey Poo was 1960s technology. State-of-the art nuclear reactors are more reliable and less maintenance-intensive than their 1960s forebears. So just because Nukey Poo required an on-site crew of 25 people, it doesn't necessarily follow a lunar reactor would.

The reactor could be remotely monitored and controlled from Earth, and some maintenance tasks could likely be performed by robots–not possible in Nukey Poo's day. There would still likely be some maintenance tasks that would require humans on-site, but that might require significantly less than 25 people.

For improved safety, a lunar reactor could be situated several kilometres away from the nearest human settlement, and left unattended most of the time. Humans (travelling in pressurised lunar rovers) could visit on those occasions when in-person maintenance was necesary.

Another factor which added to the cost of Nukey Poo – under the Antarctic Treaty, it is prohibited to dispose of nuclear waste in Antarctica, so the whole site had to be disassembled and cleaned-up and all waste shipped back to the US via New Zealand, at great expense. By contrast, a disused lunar reactor could likely just be abandoned in-place.

I agree that systems that are virtually public utilities at this point should be operated more transparently. Google can put whole swaths of legitimate businesses out of business with minor tweaks of the algorithm. We complain about SEO but how do we know Google is optimized for search quality vs their own financial gain?
This is tangential, but I really cannot understand why you would think data provided to LLMs would be "less actionable." Our own dialogues, questions, and interactions are creating the most accurate and informative personality mapping available. The amount of data harvesting available (and certainly happening) here dwarfs even Google, because Google [mostly] loses you after a click through while for an LLM they get to capture the entire interaction on any given topic.

Intelligence agencies, politicians, advertisers, and so on would pay a tremendous amount to be able to query this data. And OpenAI is being backed by Microsoft, while Anthropic is being backed by Google and Amazon. Companies all well known for their tremendous regard for user privacy and rights...
Yes. It's drastically different from every other model in that. All OpenAI models and most local models are trained to be neutral helpful robotic assistants. Opus is way more human-like - it understands subtle intent and emotions much better, it can adopt any personality and is actually smart enough to use it. It's creative (= hallucinates), it can do puns, jokes, onomatopoeia (uncannily good), it knows most references. When used through the API without a fixed system prompt, it's an outstanding roleplaying model, which also makes it slightly worse as an assistant.

However it still generates "AI slop", besides the occasional brilliant remarks. It needs to be optimized better. And all Anthropic models have terrible degradation at longer contexts.
Older versions of strace (like in RHEL 7) did not have such an option.
> A nuclear war is scarier, but none of the fallout is going to reach the South Pole

The South Pole is within easy reach though, why wouldn't a colony on it get targeted as well?
It supports playing audio files; got added quite a few years back. :help sound-functions.
An antarctic base/colony would not solve a number of issues:

1. A meteor strike can be big enough to obliterate anything on what was once the surface. It can heat the entire globe to 100 degrees Celsius due to tektites bombarding the surface.
2. Due to millennia of snow and ice covering it, the surface of the continent is just bare rock. Nothing will grow there without significant amounts of soil moved to it. Yes, this is also a problem for Mars, and a boat is more proven tech than a spaceship, but the removal of all ice off the surface will not change Antarctica into a bountiful oasis. Making a self-sufficient colony there is going to be extremely hard.

Musk is using SpaceX to drive down the cost of sending things into space. This greatly reduces obstacles for going to space, and makes a self-sufficient Antarctic base a bit obsolete.
What's the benefit of using an asynchronous event driven system if you can't process any of those events without performing a synchronous query back on the same provider for all of the necessary data?
From my very limited understanding GPUs have become even more general purpose. If your past expertise was programming / architecture areas, then you might need to brush up on your linear algebra. However, it appears that the majority of AI/ML work is in data cleansing and using the various toolkits and frameworks.
I just signed up and could see that they do provide an API to enable what you are suggesting. Hope this helps.
Does your main have an assert(false) after the main loop? If so the return address could be set to the assert function as some kind of optimization.
It's not "I have no clue". It's about what do you mean by "clue", i.e. semantics discussion. I'm trying to figure out what does pjmlp really means by OOP. From what I've seen, it's basically a checklist of features, and the more features you check out, the more OOP you are. What I've learned in uni was basically languages derived from Simula/Smalltalk lineage.

If you presume for a moment, pjmlp is 100% in right. Then it's difficult to find a language that isn't OOP. What is the informational contents in saying well C is OOP, Java is OOP, and Rust is OOP? I mean, you could with a straight face claim that Assembly is OOP, since it has some ad-hoc polymorphism.

Why is this important? If the informational content of a statement is low, "language is OOP" approaches the value of "language is language". An utterly useless statement.
You can say the sky is blue - that's a useful statement, based on that you can predict sunny weather. Or "sky is red" again useful, you can predict it's probably sunset. But if you say "sky is in one of visible colors", that's useless.

Is this really different from other language paradigms? I can quickly identify and recognize a structural vs non-structural language (presence of if/else/while, lack of dedicated GOTOs). But because the OOP property of language is so nebulous, it's difficult to identify it. And knowing something is OOP doesn't help you.

----

It's in my opinion, much better to look at what languages can do or can't do. With that in hand, you start to see how Rust OOP is nothing like Java/C#. And how C OOP is nothing like Rust or Java OOP.

Want to implement DOM in Rust? You're going to have a terrible time because it depends on the presence of some kind of inheritance mechanism. And that's very useful for a programmer because it's information you can use for reasoning.
This is lame, the world needs smart people like you solving real problems. A cool project but dumb as hell at the same time.
If there is a self-sufficient colony there, and it consists of people from a single nation, it will be targeted. Only a non-political, mixed-heritage colony of scientists and farmers might be overlooked.

Seems counter-intuitive to have it explain it's not a person from the first-person. I (a person) would have preferred it output like:

"This output is from an artificial intelligence"

"This conversation isn't remembered, saved or updates"

"This output is designed to feel like a warm relationship"

See, now it's much more obvious. The problem is that it's blunt, it'd make lines like "this isn't saved" now technically incorrect, and won't be as effective in "connecting" with people, which is what people are so excited for.
