“Kalman filter” usually refers to “linear quadratic estimator”, which assumes a linear model in its derivation. This will impact the “predict“ step at the very least, and I think also the way the uncertainty propagates. There are nonlinear estimators as well, though they usually have less-nice guarantees (eg particle filter, extended kalman filter)

Edit: in fact, I see part three of the book in tfa is devoted to nonlinear Kalman filters. I suspect some of the crowd (myself included) just assumed we were talking about linear Kalman filters
What an interesting way to send money to people without being tracked.
It's true, once a secret is exposed then you become copy-able.

But in reality it's more complex than that, because the secret maker has the advantage of momentum and someone copying you only has a snapshot in time (when they saw how you do your magic).

Fighting patents are extremely expensive, and ensuring your product stays locked to your patent is equivalent to circling your wagons around the patent. The world moves on, new technologies are released, new languages, now you are scared to move forward because protecting your patent means you have to stay locked to that idea.

I would never patent software again
So matrix is commercialized now and the "real" software version is as expensive as Slack/Rocket? That's really disappointing...
You can't GC together with the host environment if you do a custom GC (i.e. a wasm object and a JS object in a cycle wouldn't have any way to ever be GC'd).
I would rather do that as two commands than to scroll to see the output of each.
At the end of the day, the money has to come from somewhere.

I'm not sure if it's related to how kids are taught to hold the pen. And the pen itself. In India as a kid, that was really long back, ball pens banned, you had to use fountain pens. And I hold the pen like it's featured in most pen ads.

When I spent time in East, like Singapore, Malaysia I was shocked to see people holding pens like they're about to stab the paper. Even kids. But I did learn they also had fountain pens only rule for a long while before relaxing.
The fundamental issue is extremely pro-AI people do not respect any creative endeavor at all, and therefore all of this is unknowable to them. They don't know why people are interested in art or why people want to make art; movies, images, music, any form of creative expression; they simply know that people are interested in those things, and that various AI models will let them make those things without investing into the skills to execute, or indeed, even the vision to know what they might want to make. To them, a movie is not a thing you make because you want to express something: a movie is a product, brought to market, and people then pay tickets to see, and they see things like Sora as a way to make movies that people will want to see. This is the only way that the way they talk makes any sense: because they don't know why people want to see movies, them wanting to see it is treated as a given. Of course they'll want to see it, it's a movie.

And like, this isn't that weird. This is the mindset of every money-minded media executive that exists, and is why studio meddling in projects is almost universally bad, and the more meddling there is, the more frantic focus-group testing that's done, the more diluted and bad the art comes out in the end. Classic example is the original theatrical release of Blade Runner which was subject to tons of studio interference before it's release, and the studio's version is so legendarily bad that the studio itself, decades later, has all but fucking buried it at sea.

It's this particular kind of brain worms that infests people who want to get into that space, but have no desire to cultivate skill. They want to make things people love and/or get the money for doing so, but they have no idea why people make things, or why people want the things people make. Hence why all of them are tripping over themselves for their imagined AI future.

And if you think I’m being elitist or whatever, I’m just reading the marketing here. All of this stuff is sold with the primary selling point being you can make stuff without learning the skills required to make stuff so it’s naturally going to be most appealing to people who lack skills and see the acquisition of them, or more likely the difficulty involved in that, as something they don’t want to deal with.
This makes great sense to me, but just curious if you or others have a theory as for why Google routinely directs me to “content mill” churned “detritus” as opposed to engaging expert content?
Please don't accuse people of engaging in "low effort" comments. It doesn't add anything to the discussion. You can see that I've actually written quite a few very good and well-thought responses to discussion points raised by others. It's anything but low effort.

In a discussion where the First Amendment related to speech is at the center of the discussion, it's important for people to define what they mean by First Amendment Association versus Freedom of Speech as defined in the First Amendment, especially when the discussion is primarily framed as an issue relating to Freedom of Speech. If someone is asking for clarification of what someone else means, that adds to the discussion, it doesn't detract from it. We can't discuss things if people are unwilling to explain what they mean, particularly within context.

To that end, I'd encourage you to read the section on Limits on the Freedom of Association in the article you provided to see why that line of reasoning doesn't apply here.

Again with Nat Turner you are just shifting the goal posts of course he didn't have billions but he did successfully kill a lot of whites and was feared and put up as an example of the dangers of ending slavery. Ethnic hierarchies by law with legally different rights based on one's ethnicity have all ended except in Israel. All what you are talking about are not legally encoded hierarchies. You're kind of just floundering so I'll leave you to it. Like I said before, and you didn't respond to, I believe in the people of Israel. They will not let their legacy be one of legally encoded ethnic hierarchy. They don't want to be China or Russia, they want to be America, where even the ethnically cleansed Native Americans are equal citizens (to use your own analogy) with equal voting rights and all

The Sonnenschein-Mantel-Debreu results after thirty years (2006) [pdf]
> the mall

>> If you have the people, and the apparatus to dedicate to wholly one structure, you probably can save it. The actual firefighters were simultaneously fighting hundreds of house fires

> had the FD had water

>> they were 6-8 hours into the firefight before the hydrants became an issue and ~15-17 hours in before the tanks were fully exhausted.

To elaborate further for you, that means a huge portion of the damage took place before hydrants were an issue. Furthermore once there was an issue, the professional firefighters had the same exact same sort of mobile water tankers supplying them as the private company you mentioned. No professional firefighter has indicated that more water availability would have materially changed the situation.

> defunded

>> about a 2% reduction [YoY].

>> Los Angeles (City mostly, but also County) clearly need a bigger fire department, with more people, stations, and equipment.

Elaborating, in general I think Crowley and Park are completely correct, that LAFD staffing should have kept better pace with population growth. That's a much broader and more diffuse problem though - that of the FD being able to keep up with their day-to-day mission.

However, even if LAFD had kept pace, and therefore was 50% bigger than it is currently, that doesn't substantially increase the response. LAFD is already not the largest FD in the area, and the mutual aid system pulled in LACoFD and many surrounding FDs. A 50% larger LAFD increases the size of the response by <<50%. In the morning after the Eaton fire, one of the commanders outlined the problem thus: a typical structure fire needs multiple engines for multiple hours. Fighting every concurrently structure fire would have demanded thousands of engines - in his estimation more engines than exist in the state, nevermind in Los Angeles and neighboring counties.

So on the specific point: of course -2%YoY funding shifts the margin slightly, and Crowley is right to complain that every dollar will shift the margins of the department's capability, and of the day-to-day mission will feel the shift in margins. But no counterfactual policy choice short of "we spend the next 3 years' revenue on fire engines, and put them outside every home in the city" shifts the margin enough to make a difference to disaster of the scale experienced. So no, one responding FD cutting its budget by 2% played ~no role in the outcome.

Not at all my experience. My Italian bees are pretty hot though, so that may be why. My Russian bees are much nicer, and I've never been even stung by one of them, so maybe that's it. My hot bees will rip their stinger out within a second, and they emit a very particular frequency that I feel and that lets me know very quickly that I'm in trouble -- to be fair I've only experienced that vibration a handful of times because I've gotten much better at not leaving any exposed skin or any way for them to get in my suit.

All those bee rescue videos you see where the beekeeper doesn't wear a veil are not telling you the whole story. Before they go work on extracting the hive they'll first check that those bees are not hot and angry. If those bees are africanized then they'll use a suit and smoke and they will not bother making or posting a video about it. I.e., those videos are all cherry-picked experiences, all the good ones.

The extensive documentation and the vast amount of widgets were definitely the main reasons why I have chosen to do it in Python/Textual rather than other languages/libraries.

Though I don't agree with all design decisions, and there are some bugs, having such well-maintained documentation and clean repo makes it easy to dive into the project and understand what is going on and how other components are built.

Thanks for the library!

How about a naive Bayesian Bag of Words? Just find/scrape/generate with an LLM a large enough corpus of products/services, build the term frequency matrix, calculate class priors and P(term|class) and inference with straightforward application of Bayes theorem.

This particular problem, at least to me, seems trivial, and to use an LLM for anything like this for more than a hundred cases seems incredibly wasteful.

I'm surprised you took away from this that I think the goal should be making more humans because that's not what I believe and not what was I was trying to communicate.

Look: I live next to a reservation, where the US gov committed war crimes. There's a fort up the hill a quarter mile up from where I am, which was a "residential school" where the US gov put kidnapped children to "educate them".

You are 100% right that democracy can coexist with all manner of depravity.

We get it, yall can happily do enact horrors you feel like enacting on the rest of us and still enjoy feeling smug that we don't like it.

But that fact means that something being "democratic" does not mean that we should respect what you do just because you have a veneer of democracy across it.

I am profoundly grateful I have so many greater crimes commited by the US to contextualize what, in the big scheme of things, is a meaningless and goofy action. If I didn't know that they were spearheading the literal ecocide of the planet while incarcerating more people than have every been locked up, while simultaniously funding a genocide in Israel, I'd probably feel like this is some kind of espeically bad thing.

But it's not; it barely even registers once you start looking at the millions of people that the US has directly murdered in the last 250 years.

Yes. The article is about how a particular open source Matrix server implementation isn't suitable for millions of simultaneous users, and you should pay for the non-open-source version.

But if you are merely handling tens of thousands of users, no problem. And if you have the budget to handle millions of users, maybe you have the budget to pay development as well as operations staff?

If you want to study a quantum mechanical system in equilibrium at inverse temperature β, the interesting quantity is the partition function Z = tr exp[-β H]. This can be converted into a path integral Z = ∫ dφ exp[-S[φ]] which can be importance-sampled via the Metropolis-Hastings algorithm [mh] via Markov-chain Monte Carlo.

This approach is commonly used in lattice field theory [lft], where the Hamiltonian H is that of a discretized spacetime (or the problem is formulated in terms of the action S to begin with).

Real-time problems in quantum mechanics involve exp[i t H] which brings a horrible complication called the sign problem [sign]. The one-sentence summary is that exp[-β H] is positive-definite but exp[i t H] is not and it's not clear how to incorporate a complex Boltzmann weight as a probability for MCMC.

Ask HN: How much [more] value to AI do declining social media platforms have?
Clearly both X and Meta are trying to leverage the massive historical dataset they have of real human interactions as an advantage as they pivot into becoming AI companies. Neither of their social media platforms are on the assent anymore.

I’m starting to wonder though if these datasets really are as valuable as they think and if they will remain valuable as this space matures.

Thus far, I don’t know of anyone using Grok or LLAMA. Are these pivots gonna be too little too late? Are these companies on the verge of rapid implosion?
I suggest this depends on the exact model you are using. On Alder/Raptor Lake, the E-cores run at 4.5GHz which is completely futile, and in doing so they heat their adjacent P-cores, because 2x E-core clusters can easily draw 135W or more. This can significantly cut into the headroom of the nearby P. Arrow Lake-S has rearranged the E-cores.
In cryptographic contexts (as opposed to English in general) "X is derived from Y" usually means that Y is the only information you need.

> A lot of people do not want to look at and understand domain names, instead they want to see a name and a check mark. They want a central authority to tell them who is trustworthy and who is not. Domain names are a great solution for technology-adjacent people and I hope that they become more widely accepted, but I'm not too optimistic.

As with most things of moderate import or more, the vibes matter.

Setting up your own domain is pretty simple, but it is also daunting for people their first time.

Even with all the hand holding in the world, without 1:1 human interaction most people won't make that jump.
