>I will work on adding somewhere in our docs some metrics for this kind of thing (I think it could be helpful for many).

Certainly! A comparison of performance with specialized tools for large point clouds would be very interesting (like cloudcompare and potree).
>The reason I think UBI won't fix much is, UBI cannot give people purposes to live. Obviously we already have enough material wealth for everyone and UBI is just a confirmation. But "meaning" is always a luxury, and will be more so when less people need to work.

I agree that people will still want/need meaning, and some may lose it, along with their jobs, but having the money for basic needs by default gives you the ability to explore your interests with less risk. You can spend 6 months learning to paint or program or write stories without worrying about food and bills if UBI is properly implemented. If you miss your tech support job, you can go idle in 30 channels on Libera and help people that wander in asking questions about whatever software.

What am I missing here? People giving up without trying to find something to do? People who feel useless if they aren't the family breadwinner? I personally look forward to a day when most people don't need to work, and instead can "work" on what they choose.
From what I understand they are horribly mismanaged and made some terrible Amazon and Boeing management hires in the leadership ranks. Lots of good engineers who are probably looking for better opportunities though.

Nim is pretty close to that for me. It’s more pascal-ish inherited but has a sophisticated type system including case types similar to ML sum types and compile time.
Am I the only one who doesn’t find the results promising?

This is a ton of compute power and complexity for what is basically a shitty AI. It has no practical purpose. Better AIs have been built with less, why don’t people appreciate them? Or do we just take them for granted?
Oh that's a great list!

Makes a lot of sense, thinking about it. I.e. the models that presumably have been given access to calling out to "live functions" can do stuff like that and/or have been specifically modified to answer such common questions correctly.

I also like it when they just tell you that they're a language model without such capabilities. That's totally fine and OK by me.

What I really don't like is the very confident answer with a specific date that is so obviously wrong. I guess the October 2023 thing is because I've been doing this with models where that's the end of training data and not others / retrained ones.
American tech workers need to start paying attention to Chinese national policy, the National People's Congress is happening right now and it's how China sets long term goals and targets.

"Made in China 2025" was a massive national strategic plan that was 10 years in the making, and was designed in 2015. It laid out all of the key sectors for "value added manufacturing", and by most accounts, they've been delivering and meeting their targets despite all the number fudging you want to point out. None of this is particularly secret or pernicious like western media tries to portray. Just follow the news. The next 5-year plan is being set now.

Build up and debug the chain as you work in an environment like Jupyter. No need to create variables. Just run the code and verify that the current step works. Then, proceed to the next. Then, put the chain in a function. If you want to be nice, put a .loc as the first step to explicitly list all of the input columns. Drop another .loc as the last step to validate the output columns. (This also serves as a test and documentation to future you about what needs to come in and out.) Create a simple unit test with a sample of the data if you desire.

I've found that the constraint of thinking in chains forces me to think of the recipe that I need for my data. Of course, not everything can be done in a stepwise manner (.pipe helps with that), but often, this constraint forces you to think about what you are doing.

Every good Pandas user I know uses it this way. I've taught hundreds more. Generally, it feels weird at first (kind of like whitespace in Python), but after a day, you get used to it.

> We no longer have shared values, shared religious beliefs, shared customs, or really shared much of anything any more.

We never had any of these, except for, possibly, just one shared belief: the idea that a constitutional democracy was the best sort of government to live under.

What we did have was a media/cultural environment that glossed over the differences between people, minimized various minority demographics, and worked hard to convince everyone that "we're all Americans and we all believe, do and want the same things". But that wasn't true then, any more than it is true today.

I want our shared national identity to be limited to our belief in our form of government. I don't want to have to know the same songs, go to the same church, drive the same car, watch the same shows as everyone else, and I don't think they should have to do that w.r.t my choices (nor are they likely to want to).

That was the beauty of "American identity", but even the belief in our form of government has been severely eroded. By whom or why ... I'll leave unremarked upon here.

I didn't read the source, but from the description it says it uses memory mapping. So my guess here is that IO isn't so much of an issue since prefetching can hide away the latency if you are able to memory map a large enough segment of the file.

Iff the statement about prefetching is true though, I wonder how the prefetching wouldn't be bamboozled by the multiple threads accessing the file.
I’ve lived in the neighborhood for over sixteen years and am raising a family there.

There’s a lot to say about the crime factor, and it’s complicated. I will say that it’s common to miss it if you don’t happen to witness it. Streets that look quiet, well-developed, and peaceful will suddenly become violent and then go back to normal as if nothing happened.

I also lived on Drexel for a few years. A graduate student was shot and killed nearby while walking home. Another night we witnessed a drive-by shooting while eating dinner. I’ve got a number of crime-related stories after living here that range in severity from “funny-in-retrospect” to “somebody died.”

Something that still strikes me is how crimes can happen right outside homes without anyone noticing. The University Police have a daily email list of “serious” incidents that I check - I’ll often notice a carjacking or home invasion within 500 feet of where I was taking a nap on my couch.

It’s a great neighborhood with a lot going for it, which is maybe part of what makes the crime issue so hidden. It doesn’t look sketchy or violent until it suddenly is.
>One amusing issue we had in developing this idea is that frontier models have an aversion to creating entities called 'GunTurret' etc - as it goes against their constitution! (perhaps we should rename turrets to 'SuperSoaker' or something)

This sounds like a great idea for a short story in the style of Malak by Peter Watts. Imagine a future warfighter AI that has been fitted with a set of filters to make it think it's really having a pillowfight or building a factory to make screws while it's actually tearing people apart or optimizing a military production line.

How exactly are you going to be able to trust elections at this point? I don’t mean as some kind of conspiracy theorist but in a very practical sense that I can’t think of any meaningful controls or external oversight mechanisms that I could point to.

They were literally one of the very first things he got rid of and now all of the voting infrastructure is controlled at the state level by partisans who have shown loudly and clearly that they have no interest in playing fair.

Putting all of your eggs in the free and fair elections category is genuinely not a credible plan at this point.
I think that what sets this type of apart is its position as a response to the fatigue people feel from social media in its current form. I don't think something like this would have resonated as much when social media was in its infancy.

I'd love to see the price continue to come down, so more and more folks can get these products. Compared to the expensive install of a large battery systems, I'd call it a step in the right direction but I agree we need to make these even more accessible. Features like energy management and demand response can improve the economics in some markets, but low upfront cost is the ultimate goal. Most of my family in Louisiana are similarly not considering smarter backup systems seriously because of the cost and either "do nothing" in outages, rely on neighbors' generators, or have unreliable pull-start generators in their garage.

Yes, yes, and yes on offline performance! We're on it!

>that a lack of unifying identity in America is a weakness, not a strength

America's proper and authentic identity always is its pluralism, entailing all the conflict that brings. If America made one unique contribution to the world its that it has shown how identities, plural, can be built from the bottom up and are in constant tension with each other, and that this is a feature, not a bug.

An American government trying to impose identity, by renaming lakes and mountains, mandating language(s) or what have you is so performative it looks more like North Korean state television than culture, it's utterly foreign to Americans and going to fail for that reason. Americans are instinctively allergic to having culture, regardless from what direction, declared on them by fiat.
Another experiment to watch. Natural versus synthetic is utterly orthogonal to tested versus safe.
Now in Canada we have people driving around with US flags and TRUMP stickers on their cars.. there are several communities that have formed backing this idea, in seeing slogans such as “Free Alberta” and “Alberta 51” as well as an ongoing narrative that Canada is no longer a nation and we have no more borders.

If Trunps plans was to disrupt Canadians internal politics, he has certainly succeeded.

Additioanllly the Liberal party had leveraged this whole thing to distract people from its own failures during critical election time by framing US as our enemy and attempting to win votes against conswervatives.

The whole situation is unhinged.
And yet they do [1]. I'm not saying that the expectation be there for all interactions in the country, I'm saying the expectation should be there if you are about to be charged with a crime in that country.

Why should that be an expectation? Because if you or I am being held against our will, wouldn't it be nice if you had an interpreter who could translate what the officer, lawyer, and judge are telling you? IE, if they tell you "you have to do this to not be locked up for 10 years" wouldn't it be nice to know how to comply with a ruling against you? Wouldn't it be nice if when they asked you questions you could actually answer them?

Adding another comment because I can no longer edit my original.

- Power instability causes serious economic damage to individuals, families and small businesses. Imagine establishing a business in an island where you don't know if you'll have power today.

- In PR, you don't buy groceries for an entire month. The power goes out once and all your food is ruined. Families bear the brunt of these reliability failures.

- Outages damage your appliances. This is even more economic damage to families and the poor. A couple years ago, in jest, protesters from across the island took their damaged appliances to the power company headquarters and dropped them off there.

- Diabetics have to use generators or special machines to keep their insulin refrigerated.

I could keep going. It's a shame that this absurdity is happening in the wealthiest country in the world.
1) Can't be automated without a failover switch to disconnect the house from the grid so it doesn't back feed into the actual power lines outside the house and either break or risk injuring linemen who think a line has been disconnected and isolated.

In addition to that you're feeding energy back in through a much smaller wire so you're limited to the capability of the circuit it's connected to and the devices have to be smart enough to actually limit their output to what the wall can handle. Otherwise imagine you have 2 of these each on 1000W circuits (not a normal circuit but for convenience lets pretend) and you have 1500W of load running elsewhere in the house. One runs out of power because it had a lower charge state when power failed, now unless the remaining UPS limits it's output and browns out everything you're pulling 150% the rated power of your circuit, potentially damaging the wires or the loads you're powering.

This is potentially what's causing fires on nVidia's high power connectors, one connection wears out or is simply loose so more power flows through the remaining pins and it's too much for those wires causing fires/melting the wires.
It's a flimsy argument for sure. But we live in a reality where Meta, Google and other past bastion of progressive movements have taken a 180 turn upon Trump's first week of reign. Is it that much of a stretch to assume that a large swath of DEI champions around us were just parroting performative mantras?

Maybe hypocrites are pretty obvious to spot for you. It's not as easy for me. I was shocked to find many of my peers turn their noses at DEI policies and act as if they've always been against it.

Bandwagoners are going to bandwagon. I personally don't see much use in labelling them as anything else.
Yeah but it's also preference. Some people like to read the facts and then come to their own conclusions. I think it can be interesting to read an opinion / column so now and then, to see someone's perspective. But I think it's important to also think about the stuff that's happening yourself, and not just take the opinions and views of someone else.
My understanding is that the composition of each body is different. There's the obvious: More ices and liquids comprise Ganymede, possible since Ganymede is so distant from the Sun. And the not-so-obvious: Mercury is anomalously dense due in part to (likely) having a disproportionally large core of iron and nickel.

I find Wikipedia's discussion about Mercury's density in contrast to Earth's fascinating [0]:

> If the effect of gravitational compression were to be factored out from both planets, the materials of which Mercury is made would be denser than those of Earth, with an uncompressed density of 5.3 g/cm3 versus Earth's 4.4 g/cm3.

What I think will happen is the US tries to mimic China by creating an even lower class of our workers that form a new industrial/manufacturing base to compete with.

This becomes less of a difficult pill to swallow if a) we're involved in a trade war, b) the economy has crashed and we must work our way out of it "for the country", c) the right people get enough money.

They're too smart for mass murder because that would actually spark a resistance, not to mention get other nations involved. I don't think a sweatshop labor economy will spark a resistance because we can't even resist our current labor abuses (and neither can that segment of China's population).
I think he is talking about a human using the programatic API the LLMs are using to play the game. I think that would be a whole lot slower than normal playthrough
On a personal note, I'll also be really stoked when we're shipping to Australia. Lots of friends down there, and have been lucky to work on some past home energy products for the Australian market.

Parts of Pila's power electronics are already 230~240V capable. We've just launched in the US, and are doing our best to stay focused on excellent support for our home market before expanding. That said, I could see 2026 being the right time for expansion... stay tuned mate!

In my adult life, the only time I can ever remember the consensus that the economy was good was Christmas 1999.

The internet gave people hope about the future in 1999 but now with the internet our desires can never match the reality that follows.

Instead people live in either a post-bubble crash that is about to crash further or if things are going well that just means we are in a super bubble that will have a historic crash. Repeat.
Growing up, I remember throwing my dog food. It was just amazing, the food would arch up, intersect with his mouth, and just... disappear.

except grapes. They would arch up, intersect with his mouth, and... hit a tongue and roll off onto the floor.

turns out grapes (and raisins) are toxic to dogs. How they figure that out during the millisecond encounter with the tongue is mind-boggling.

oh, another one: one time when young I gave my dog a corncob to chew on, my theory being it would be like gnawing on a bone. and it he just ate it. it disappeared. we monitored him, he was fine, but scared me to death.
The intuition for ML-KEM-style lattice cryptography is actually kind of straightforward. Generate a secret vector x and a random matrix A; multiply Ax, then corrupt it with a random vector of errors e, so instead of Ax=b you have Ax+e=b.

Solving Ax=b is like week 2 of undergraduate linear algebra. Solving Ax+e=b, in a lattice setting, is Hard in the same sense factoring is: as you run the steps of elimination to attempt to solve it, the errors compound catastrophically.

> Has there ever been any petition in the UK

Online petitions are useless for anything beyond harvesting a list of potential donors.

The value in a petition or
protest is in demonstrating commitment. If you’re willing to fill in a paper form and/or show up somewhere inconvenient, you’re might also be willing to phone bank (and petition for) a primary opponent.

Online petitions do none of that. If an issue has lots of online petitions and nothing else, it’s almost a sign that its base is electorally useless.
Realistically, I would not have been able to own my car, which is rapidly depreciating to nothing, without my land on which to park it. Are you suggesting that I should start telling people that my car is worth hundreds of thousands of dollars? I'm quite sure I'll get a lot of funny looks, and probably some angered questions from my financial associates, if I heed your advice, even if it is actually true under some sort of accounting methodology.

You are right that in practice a house requires land, but that does not mean that houses and land are the same thing. Especially given the context here about being able to build where you please, which explicitly took land constraints out of the equation.
