> it was only very recently that your 64 core CPU stopped pretending to be an 8086 during initial boot

Still Does[1]:

>> After a RESET or INIT, the processor is operating in 16-bit real mode. Normally within real mode, the code-segment base-address is formed by shifting the CS-selector value left four bits. The base address is then added to the value in EIP to form the physical address into memory. As a result, the processor can only address the first 1 Mbyte of memory when in real mode.

The UEFI hands off the boot CPU to the OS loader (GRUB/NTLoader etc) in long mode. But when the OS brings up any CPU that is not the initial bootstrap CPU via the interprocessor interrupt... that CPU comes up in 16bit* real mode.

[1]: https://docs.amd.com/v/u/en-US/40332-PUB_4.08 (the intel one says the same thing last I checked, Intel has discussed changing this... but AFAIK has not yet)

* This is a lie... note how the quote references EIP and not IP? That's because it's actually booting up in Unreal mode. Hence the initial instruction run is actually at 0xFFFF_FFF0 IIRC

Related: All LLMs have struggled helping me generate OpenSCAD models for 3D printing. They can’t seem to reason through XYZ space and 3D math. It’s my current litmus test for LLM performance.

I have had moderate success describing things as geometric primitives. I.e. making a simple phone stand is hard to one shot. Had to do it in steps as make a plane with XYZ dimensions, rotate it X degrees up, calculate the height using trig, create another plane with that height, translate to X position. Etc.

Nice. Those activities remind me when I used to visit my dad countryside (he lived in Tuscany). He's legally blind though, and we managed anyway. Not sure why the last bit would be car enabled. I was in East Hamptons a few weeks ago and the kids would play outside while we stayed in the living room/kitchen. We just had to be careful about the pool.

Nah. There's huge alpha here, as one might say. I feel like this comment could age even more poorly than the infamous dropbox comment.

Even with Jax, PyTorch, HF Transformers, whatever you want to throw at it--the dx for cross-platform gpu programming that are compatible with large language models requirements specifically is extremely bad.

I think this may end up be the most important thing that Lattner has worked on in his life (And yes, I am aware of his other projects!)

> The random insinuation halfway through that ancient humans had secret advanced civilizations seems completely uncalled-for, and would put any discerning reviewer on edge.

Are you referring to Peratt’s quoting Mallory? That section of the paper is simply a review of historical work on petroglyphs and insinuates nothing at all. Context is a thing.

Ten years in, Rust jobs are barely 10% of C or C++ jobs, if that. In any market segment, that is not the kind of adoption that successful products usually display.

Judging from the emotion in your comment, I sense that I did touch a nerve, and I'm sorry. As a programming language/platform professional, I'm obviously interested in both language design and market adoption, and I share some of my personal perspectives. That Rust's adoption is significantly lower than that of programming languages that become dominant - in any market slice - is not something I thought is controversial, regardless of one's like or dislike of the language. But I know that some programmers make their programming language preference a part of their identity, and react emotionally to analyses or opinions they don't like.

It's normal to disagree, as experts often do, but once it gets emotional, perhaps it's best to turn away. So I apologise for causing you discomfort, and perhaps if you find my comments too distressing, just skip them and move on. Getting stressed about things like this is not worth it.

For anybody into prehistoric abstract symbols who hasn't encountered this, "The Signs of All Times 1988" [1] is a super interesting study. Also very readable for the majority of us who are not in the field. Pairs nicely with Herzog's Cave of Forgotten Dreams [2] and any mid-tier Cabernet.

[1] https://www.jstor.org/stable/2743395

[2] https://en.m.wikipedia.org/wiki/Cave_of_Forgotten_Dreams

And just my two cents as an under-qualified former art history teacher...

It's fascinating and totally valid to try to analyze these symbols as proto-linguistic, but it can be even more interesting to imagine the cognitive roll these kinda of abstract symbols might have played outside the scope of language as we understand it.

Trying to imaging the structure of the mind and experiencing reality with a complete absence of language can be immensely mind-expanding, even just as a thought experiment. At least it was for me.

I understand that. What I’m saying is that the capacity is different depending on how quickly you drain it. Different battery construction can mitigate this effect to a higher or lower degree, but the battery is rated for 200A discharge in one hour. At 380A you will get less total watt hours out of the battery than you would at 200A, ie it will discharge in less than the 31.5 minutes you would otherwise expect.

I skimmed the papers, because I have not the time to read them in detail.

But let me tell you this: even as a non-expert, comparing the pictures of the claimed phenomenon with various pictures of petroglyphs it's pretty clear that the correlation is extremely loose. And there's nothing in the text I skimmed to address some of this misses.

Maybe you can tell me though. For the images that most identify as depictions of humans that the paper instead identifies as a toroidal flux tube around a plasma column because of the presence of two round dots: how does the presence of many similar human-like figures without those two dots match the same phenomenon?

To put it in really frank terms: this field is problematic in general because spurious correlation is really common. So any paper needs to start by demonstrating not merely correlation but something that makes it seem actually causative, some other factor to make me believe that it might be true. Without that link, Occam's Razor says it's just another thing on the heap of spurious correlations.

Keep every pin and passcode in an app with the encrypted safe or copy on a thumb drive or even file share. It's encrypted. Even your phone pin. The app just needs the one (Very long) key.

Give it to a trusted person with the key, or just the key if shared.

Or variations of the above.

Fire danger? Store your key docs in the same storage. Encryption not needed. I do keep originals in the evac kit.

Some of those don't make that much sense...

Property tax eh? kind of depends on cost of the things that are paid for by property tax. Sometimes that'll be higher in urban and sometimes higher in rural.

I don't know why I should pay extra fees to keep my many cars on my property... that's why I have my property. I don't mind license fees, and I grumble but don't mind that they're higher for my PHEV even though I don't drive it much or plug it in. If I was parking on public right of way, it might make sense to charge me per car, but my cars don't use shared resources when they sit at home, and I can only drive one at a time.

Where can I live where I don't have to pay full price for extended infrastructure? That'd be great. Where I am, I have to pay my own way for my well and septic; if I wanted municipal of either, I'd have to pay for the build out to get it to my house, just like I did for muni fiber. The owners before me that had electricity hooked up must have paid the utility to extend it, and enhancements would be at my cost.

Agreed, but I do think it’s important to distinguish:

- voted Trump because they believe the constitution protects us from his worst impulses; would support constitution over Trump

- voted Trump and would shred the constitution if they had the opportunity to

I think it’s hard to say how many are in each camp. My fear is many tell themselves they are in the first, but will actually end up in the second under the correct manufactured crisis.

But the stats and polling would need to go into a lot more detail than what you quoted to distinguish.

Persistent stressors such as drought, food insecurity, and migration owing to climate change can also be major risk factors for mental illness."

> What "validating" does docker/podman pull do that is in excess of a curl of a file?

Every single thing has a sha hash so verifying that I actually downloaded what I meant to download is easy. This gets tedious if I have to `curl https://github.com/someUser/someProject/release/latest.tar.g...` and also get the `tar.gz.sha256` file (if they even publish one ...).

Curl supports resuming a partial file (assuming the sending server also does) but it can't "know" ahead of time that the first 1/3 of the file I am downloading has already been fetched because it's also used by $someOtherArtifact.

> One of the advantages of a real package manager is that it checks signatures on the content that is downloaded.

So does docker/podman.

> The supply chain on a linux distro's package repos is much harder to break into than typosquatting into a docker registry somewhere.

Perhaps. For every "secure" package repo, I'll show you a much more up-to-date package in AUR/Nix.

The system you’re describing is one where lives are enriched by this drive away from zero sum, but in my view the one we observe is increasingly described by excess and inefficiency. The middle class is shrinking in the face of technological advances. More people say they no longer expect to do better than their parents. Either the last 40 years have seen no tech progress, or he’s just wrong. It’s worse than zero sum on average, it’s declining economic conditions. It’s full time jobs that used to pay a living wage, but don’t anymore. Even over years of productivity gains (ie away from zero sum, the conditions Thiel says keeps us from violence), a great percentage of the population is losing ground.

Even in your own examples of zero sum, the reality is they are excess-driven. People go to Harvard often by competing for excess which enables contributions above and beyond what is required to pay for education — excess, not academic meritocracy. Many people go to the Olympics because of sufficient excess to spend years practicing bobsledding, not because they’re necessarily the best athletes in the country. We have an abundance of highly paid professionals working jobs they would self describe as “bullshit jobs” (excess).

I’m even saying that I have excess in my own opinion, even though I’m maybe a top 10% earner. And while people are hungry, uneducated and homeless, we have the means to resolve this with existing technology, but we don’t have an economic framework to do it.

In my opinion, the AI race could lift up everyone, or it could create greater excess and inefficiency. I’m pessimistic that recent history is showing it’s the latter.

My original point was just that even in the top 10% of earners (and probably more), violence is a preposterous idea. Seeing my peers excelling whether financially or otherwise is not going to turn me violent. It doesn’t threaten my basic needs or impact my greatest desires, which are to have the freedom to pursue things that I think are important. In my view, the fabric of society is strong when people’s basic needs are not in jeopardy, not resulting from insufficient excess.

It's an independent commission of inquiry making a report to the HRC. The commission could have reported that the moon is made of cheese, and the HRC wouldn't be able to do much about it, other than politely suggesting that they consider a revision.

Even if HRC did have some kind of oversight, current HRC members include Qatar, Cuba, and DRC for example.

> UN press release

Again "UN" is imprecise; the press release (at least the one I saw) was by OHCHR. Another of their press releases described Israel's hostage rescue operation as "the umpteenth massacre by Israeli forces".

> the UN Special Rapporteur on the occupied Palestinian territory

Who has been accused of antisemitism by several countries, and is currently under US sanctions.

> widespread militant infiltration

I wasn't claiming this.

Thanks a lot! That’s a very good point, the game layer is something I’m actively building and still figuring out. I’m actually working on a self-healing P2P network where nodes discover each other through a Kademlia DHT, connect via WebRTC (STUN/TURN for NAT traversal) and sync across different instances as a multiverse of seeds. That’s why I kept the current gamification demo more on the simple side, somehow... Let's see how it goes lol

There's a good discussion of this in the

https://www.amazon.com/Autism-Matrix-Gil-Eyal/dp/074564399X

and you can ask the question of why schizotypy

https://www.amazon.com/Schizotypy-Schizophrenia-View-Experim...

is ignored which is that by being a developmental disability "autism" avoids the stigma that a diagnosis of severe mental ilness would bring (e.g. confirmed bipolar Kanye West thinks he is autistic, Elon Musk who sure acts like he's bipolar but is not diagnosed also thinks he is autistic) If you told the parents of the kid who's being bullied in first grade who shows some signs of anxiety and seems to be dressed oddly that he has a 10% chance of losing his mind completely as a young adult they'd be horrified. Tell them that he has autism and they can get more resources.

Ah I was looking at the pg_uuidv7 python package.

The backwards compatibility is a wild trade off.

Either way my comment was hyperbole, but the concept is the same, 10000 records per millisecond and you get the point. For 99.999% of SQL use cases UUIDv7 is good.

I only advocate for UUID so much because 3 separate times in my career I have been the one to have to add UUIDs so we don't leak number of patients, let users scrape the site by just incrementing (amongst other protections). So much easier to just UUID everything.

> I’d rather just spend the brain power on ditching OpenGL, rather than trying to continue working with this broken API

Is "this broken API" responsible for a library monkey patching?

Also, we are lucky that linux libraries generally don't use such hacks. That's really bad style of programming. Also legacy games probably would run just fine with a bitblt if they were running fine on older software.

We need a Pythonic language that is compatible with the Python ecosystem designed for machine learning use-cases and compiles directly to an executable with direct specialized access to the low-level GPU cores and is a fast as Rust.

The closest to that is Mojo and borrows many of Rust's ideas, built in type safety with the aim of being compatible with the existing Python ecosystem which is great.

I've never heard a sound argument against Mojo and continue to see the weakest arguments that go along the lines of:

"I don't want to learn another language"

"It will never take off because we don't need another deep learning DSL"

"It's bad that a single company owns the language just like Google and Golang, Microsoft and C# and Apple and Swift".

Well I prefer tools that are extremely fast, save time and make lots of money, instead of spinning up hundreds of costly VMs as the solution. If Mojo excels in performance and reduces cost then I'm all for that, even better if it achieves Python compatibility.

Perhaps quite a bit more not impossible?

We only know of the symbol use (if they were symbols) that happened on media that lasted tens of millennia. If they even painted symbols on deeply underground cave walls, they likely had them on many less durable surfaces as well. There could have been a huge oral tradition augmented by drawn memorization aids on durable but not that durable media. That augmented oral tradition would then occasionally, every few dozen generations or so, due to some exceptional circumstances, spill over to the near-eternal medium of a cave wall.

Interesting. Two engineers at Apple worked on something similar that would slurp character bounding boxes from a PDF page and reconstruct paragraphs, columns, tables, etc.

It was surfaced in iOS a decade ago as "tap to zoom" feature for PDFs. It's funny — as with a lot of things there was a lot of sophisticated engineering under the hood and then marketing simply wants it to detect a tap in a paragraph and zoom to its bounds.

I can't think of the last time I read a PDF on my phone or I would test it to see if it still works as I remember.

Everything that Trump has done via executive order and proclamation should have been checked by the court, and it mostly has except the Supreme Court has granted new supreme powers to the executive that aren’t going away even after Trump leaves office. That is the biggest travesty here, the American system of checks and balances has basically been broken and nothing short of a constitutional convention or revolution is going to fix it.

I've played football (soccer for Americans) with people who were very good who didn't watch the game at all. Similarly for basketball.

People watch sports because it gives them an emotional investment in something that has a new result each week, is not scripted and shows incredible skill and fitness.

It's also a lot healthier than the people who follow politics like sport. They get moral when their team loses.

Do you watch TV, Internet videos, film, or read books ?

That's just another form of entertainment.

> For rail specifically: for rural Americans, passenger rail worth the name (aka what we get in Europe) is something that they see as unachievable, something for "librul city dwellers". When all they get from rail is noise and crossings blocked for hours [1], it's hardly a surprise that rail ends up being yet another culture war issue.

True, I meant climate change denial but I wasnt very clear. Like opposing everything that's eco friendly, not the trains in particular. But that's a point!

GP is arguing about licences. Yes, formally there is no obligation, and I'm not saying the author has any such obligation.

In the present case, either the missing overflow check in the code is by mistake, and then it's warranted to point out the error, or, as I understood GGGP to be arguing, the author deliberately decided to neglect safety or correctness, and then in my opinion you can't reject the criticism as unwarranted if the project's presentation isn't explicit about that.

I'm not making anything the author's problem here. Rather, I'm defending my criticism of the code, and am giving arguments as to why it is generally good form to make it explicit if a project doesn't care about the code being safe and correct.

> I may have an overly STEM-centric view

This is likely; international vs. US also probably makes a difference, as three of the last six US presidents (by person, not year) were Yale alumni (no MIT alumni have yet become president, but I think it's a good idea!)

And five are Ivy League grads: Obama from Harvard Law School, and Trump with an undergrad degree from Wharton/U. Penn. (Biden being somewhat of an outlier, having attended U. Delaware and Syracuse University.)
