Intel is testing BIOS updates to fix performance of its new Core Ultra 200S CPUs

Without tuned power profiles, a separate but related feature called the Intel Application Performance Optimizer (APO) couldn’t kick in, reducing performance by between 2 and 14 percent.

Current BIOS updates for motherboards contain optimized performance and power settings that “were not consistently toggled” in early BIOS versions for those boards. This could also affect performance by between 2 and 14 percent.

The fifth and final fix for the issues Intel has identified is coming in a later BIOS update that the company plans to release “in the first half of January 2025.” The microcode updates in that BIOS update should provide “another modest performance improvement in the single-digit range,” based on Intel’s performance testing across 35 games. When that microcode update (version 0x114) has been released, Intel says it plans to release another support document with more detailed performance comparisons.

If a long Intel support document detailing a multi-stage series of fixes for elusive performance issues is giving you deja vu, you’re probably thinking about this other, more serious problem with 13th- and 14th-generation Core CPUs from earlier this year. In that case, the issue was that the CPU could request more voltage than it could handle, eventually leading to degraded performance and crashes.

These voltage requests could permanently damage the silicon, so Intel extended the warranties of most 13th- and 14th-gen Core CPUs from three years to five. The company also worked with motherboard makers to release a string of BIOS updates to keep the problems from happening again. A similar string of BIOS updates will be necessary to fix the problems with the Core Ultra 200S chips.

arm-says-it’s-losing-$50m-a-year-in-revenue-from-qualcomm’s-snapdragon-x-elite-socs

Arm says it’s losing $50M a year in revenue from Qualcomm’s Snapdragon X Elite SoCs

Arm and Qualcomm’s dispute over Qualcomm’s Snapdragon X Elite chips is continuing in court this week, with executives from each company taking the stand and attempting to downplay the accusations from the other side.

If you haven’t been following along, the crux of the issue is Qualcomm’s purchase of a chip design firm called Nuvia in 2021. Nuvia was originally founded by ex-Apple chip designers to create high-performance Arm chips for servers, but Qualcomm took an interest in Nuvia’s work and acquired the company to help it create high-end Snapdragon processors for consumer PCs instead. Arm claims that this was a violation of its licensing agreements with Nuvia and is seeking to have all chips based on Nuvia technology destroyed.

According to Reuters, Arm CEO Rene Haas testified this week that the Nuvia acquisition is depriving Arm of about $50 million a year, on top of the roughly $300 million a year in fees that Qualcomm already pays Arm to use its instruction set and some elements of its chip designs. This is because Qualcomm pays Arm lower royalty rates than Nuvia had agreed to pay when it was still an independent company.

For its part, Qualcomm argued that Arm was mainly trying to push Qualcomm out of the PC market because Arm had its own plans to create high-end PC chips, though Haas claimed that Arm was merely exploring possible future options. Nuvia founder and current Qualcomm Senior VP of Engineering Gerard Williams III also testified that Arm’s technology comprises “one percent or less” of Qualcomm’s finished chip designs, minimizing Arm’s contributions to Snapdragon chips.

Although testimony is ongoing, Reuters reports that a jury verdict in the trial “could come as soon as this week.”

If it succeeds, Arm could potentially halt sales of all Snapdragon chips with Nuvia’s technology in them, which at this point includes both the Snapdragon X Elite and Plus chips for Windows PCs and the Snapdragon 8 Elite chips that Qualcomm recently introduced for high-end Android phones.

a-matter-of-taste

A Matter of Taste

In light of other recent discussions, Scott Alexander recently attempted a unified theory of taste, proposing several hypotheses. Is it like physics, a priesthood, a priesthood with fake justifications, a priesthood with good justifications, like increasingly bizarre porn preferences, like fashion (in the sense of trying to stay one step ahead in an endless cycling for signaling purposes), or like grammar?

He then got various reactions. This will now be one of them.

My answer is that taste is all of these, depending on context.

Scott Alexander is very suspicious of taste in general, since people keep changing what is good taste and calling each other barbarians for taste reasons, and the experiments are unkind, and the actual arguments about taste look like power struggles.

Here’s another attempt from Zac Hill, which in some ways gets closer.

Zac Hill: ACX is so close to getting it right on ‘taste’, but then dismisses the closest (“grammar”) conclusion in favor of a much more elementary interpretation (“priesthood of esoterica”).

Art works by leveraging the mechanics of a given medium to create meaningful experiences for an audience. This is in turn bounded by three things:

—> The nature of what those mechanics are capable of emphasizing

—> The artist’s facility with those mechanics

—> The audience’s ability to meaningfully perceive how the artist is deploying the mechanics.

The standard ‘highbrow/lowbrow’ distinction is basically just a slider on the third variable. Similar to improving at an instrument with practice, the process of considered experience and reflection of art allows a broader and more textured perception and integration of deployed mechanics.

Menswear Guy is great because he lays this process bare for a medium most of us lack familiarity with; Ebert is the same way; Gardner had this effect on me for literature. One value of the critic is explicating some of these mechanical grammars/vocabularies so we don’t have to derive them independently.

The point is that artistic “quality” can in some sense be ‘empirically/objectively’ derived by understanding those three core variables in greater resolution. Obviously this is in practice impossible, which is why discursive reflection rules. But the process is not mysterious.

If we are going with one answer from Scott’s list, it is obviously grammar. The real answer is it is all of them at different times and places.

He points to one key aspect of grammar, which is that you can have different internally consistent grammars, and they are all valid in their own way, but within each you need to follow their logic and spirit, and there is better and worse Quality.

Languages also work this way overall. Or cuisines. So do artistic styles.

So does taste. You can ‘have taste’ or ‘not have taste’ within any type of taste, in addition to having the taste to prefer the right kinds of taste, by being able to properly sort things by Quality, and create and engineer high Quality yourself, and have the preference and appreciation for and ability to notice high Quality.

Sometimes, yes, taste is rotating in the sense of fashion, where everyone is trying to stay one step ahead in the status game, but also there is a skill of doing that while also ‘having taste’ both in general and within each context, which is also being tested.

Also, yes, as we saw in From Bauhaus To Our House, sometimes the underlying logic from which taste is being drawn is, as in modern architecture, a literal socialist conspiracy intended to make our lives worse, with a competition to see who can convince more people to suffer more.

And all of this is being combined, in places like the AI Art Test, with other preferences that are not about taste. And sometimes people are trying to apply the wrong kind of ‘good taste’ test to something in a different grammar, or saying that taste should apply on the meta level between the grammars.

Thus, ‘having no taste’ can mean any combination of these (with some overlap):

  1. Too little ability to distinguish, in a context, what is good versus bad taste.

  2. Choosing taste preferences that are, at a meta level, considered bad taste.

  3. Choosing types of things where Quality and taste have relatively low impact.

  4. Failing to appreciate and take joy in good taste and high Quality.

  5. Caring more about non-Quality aspects, thus often choosing low Q over high Q.

  6. Caring about things ‘people with good taste’ think you shouldn’t care about.

  7. Not playing along with today’s status game or power trip.

  8. Failing to appreciate complex historical context that explains why a particular thing has been done before and is therefore bad, or is commenting on something else and therefore good, or other such things (see the Lantz discussion later).

Within a given grammar and context, I will stand up for taste Platonism and physics. I believe that, for all practical purposes, yes, there is a right answer to the Quality level of a given work, to whether liking it reflects good taste.

That doesn’t mean you have to then care about it in every instance. You certainly get to rank things for other reasons too. My Letterboxd ratings (from 0.5-5 stars) are meant to largely reflect this Platonic form of Quality. And sometimes I think ‘oh this is going to be a 2-3 star movie’ and decide that’s what I want to watch today, anyway. When I differ from the critics, both high and low, it’s generally because of aspects they think you’re ‘not supposed to’ care about, that are ‘outside of taste’ to them and that they think shouldn’t matter if you’re in good enough taste, but that I think should count, and matter for Quality.

I think you greatly benefit from good taste if and only if you are not a snob about it.

As in, you can develop the ability to appreciate what is good, without having disdain for things that are bad. Ebert can appreciate and understand both the great movie and the popcorn flick, so his taste means he wins. But if it meant he turned up his nose at the popcorn flicks, now it’s not clear, and maybe he loses.

Ideally, one has the ability to appreciate all the subtle things that make things in good taste, without recoiling in horror when someone has a bad color scheme or what not.

Never, ever tell anyone to Stop Having Fun, Guys.

In Sympathetic Opposition’s Contra Scott on Taste, there seems to be the assumption that Scott is right that having taste and noticing Quality means noticing flaws and thus having the experience of low Quality things be worse. Their response is to say, if you have taste, then you can search out and experience higher Quality, so it’s fine.

They site C.S. Lewis and endorse my #4 in what bad taste primarily is – that good taste is the ability to experience the sublime in things. To which I say:

  1. You can have this, while still appreciating low Quality things too.

  2. Also often the failure to experience the sublime in things that people traditionally think are in bad taste, and of low quality, is a Skill Issue.

  3. In particular, I think one skill I have is the ability to experience the sublime and aesthetic pleasure when consuming media that, objectively, is low Quality and in bad taste, that ‘objectively’ sucks, by isolating the elements that have it from the parts that suck, despite noticing the parts that suck.

  4. When done properly, that makes it better, not worse.

I also think that SO hints at the distinction between ‘good taste’ and ‘good.’

When I peevishly, shittily started a twitter fight about the mask picture by saying “it seems like people only find this image beautiful if they agree w the belief it expresses, which in my opinion is a sign of a bad piece of art,” people who disagreed with me said stuff like:

  • people are talking about it, which makes it good

  • it makes people feel things, which makes it good

  • it communicates a difficult concept, which makes it good

Literally no one defended it by saying anything about the image itself. No one was like “Look at the lines, the composition, the colors. I could just stare at it and drink it in.”

If these people aren’t having a direct aesthetic experience with this image, then it is just not possible to do so.

Which is why they weren’t saying the picture is good as in ‘in good taste.’ They are saying it is ‘good’ as in ‘fun’ or as in ‘is useful.’

Are they having a ‘direct aesthetic experience’ of its details? Not in the sense SO is thinking, presumably, but they are having a conceptual experience, and they are using it as a tool that serves a purpose. Several stars.

What is going on with AI art? It’s not good as in taste. But it’s good as in pretty.

And for a lot of people, that’s what they want.

This is also my response to Scott’s response to SO. He says:

I think that distinguishing this from the deep love and transformation of highbrow art risks assuming the conclusion – the guy who says Harry Potter changed his life is deluded or irrelevant, but the guy who says Dostoyevsky did has correctly intuited a deep truth. But we believe this precisely because we know Dostoyevsky is tasteful and Rowling isn’t – I would prefer a defense of taste which is less tautological.

So I would say, you can say that you got great aesthetic pleasure from Dostoyevsky’s prose, or you appreciated his deep understanding of character, or other neat things like that. If you say those things about Rowling then I’m going to laugh.

But Rowling still spun a good yarn (over and over again) in more basic ways, there is a lot more demand for that product than there is for Dostoyevsky’s product, and there’s no reason you can’t love Harry Potter or let it change your life. It’s fine. There are things there worth finding.

We also have Frank Lantz contra Scott on taste. It’s quite something to see your past self quoted like this:

Frank Lantz: Art skepticism seems to be a common stance among a lot of rationalist and rationalist-adjacent thinkers. This general attitude ranges from Scott’s sincere attempt to carefully think through his skepticism (he followed up his AI art quiz with a post about modern architecture and a discussion of artistic taste) to Zvi Mowshowitz proudly declaring he would never set foot inside the MoMa and bluntly proclaiming that “an entire culture is being defrauded by aesthetics”.

I care about this because I like these thinkers, and I think they’re missing something important and valuable about art. I would like to be able to defend art, fine art, modern art, as a project, in terms that they would find convincing, but I haven’t figured out how to do that yet.

Perhaps, as a preliminary sketch of such a defense, I would start by calling attention to the dynamic nature of art – its necessary and unavoidable restlessness. Every work of art is both embedded within a process of perception, reaction, evaluation, and interpretation, and also an intervention into this process.

While I stand by my statements there, and I still wouldn’t set foot in the MoMa, and you can see above what I think about modern architecture regarding From Bauhaus To Our House, that doesn’t mean I am against art or appreciating art, in general.

Lantz’s most important contribution to this discussion, as I see it, is to point out that art and taste are largely in response to the desire to avoid the boring and predictable and what has already been done while also matching expectations, and that a lot of artistic choices and good taste emerge from the detailed context of what had existed before and also what came after.

And I think all of that really is legitimate, and investing in understanding that context can pay off, and that earlier works very much are enriched and ‘get a free pass’ in various ways by the fact that they came earlier, and they were original and innovative at the time, and in what they then led to, and so on. There’s an elegant, important dance going on there.

Sometimes.

Other times, taste is functionally being fashion, or it is being a priesthood, and for Modern Art I strongly suspect it’s best classified (in Scott’s taxonomy) as bizarre porn, except in a bad way and as buildings displayed on the street.

I’m going to double down that most – not all, but most – of all this modern ‘conceptual art’ is rather bogus and masterbatory, and mostly a scam or a status game or at best some kind of weird in-group abstract zero-sum contest of one-upmanship, at worst a ‘speculative market in tax-avoidant ultra-luxury hyper-objects, obscene wealth and abject, hipster coolness,’ and also a giant fyou to humanity, and I want it kept locked behind the doors of places like MoMa so I can choose to not set foot in there.

I’m definitely doubling down on Modern Architecture.

I’m not bad at aesthetics, you’re bad at aesthetics, in that you stopped believing in them at all, and tried to darvo and gaslight the rest of us into thinking it was our fault.

Or, I’m not the one who doesn’t care about aesthetics, you’re the one who doesn’t care about aesthetics, and you’re gaslighting the rest of us.

You’re pretending to do grammar when you’re obviously doing something else.

I’m not skeptical of art. I’m skeptical of your particular art, which happens to be the dominant thing called ‘Art’ in some circles. Whereas the people I think of as ‘artists’ today that I admire tend to work with video, or audio, or games, or text, or make visual art within one of those contexts that the capital-A Art World would scoff at.

(Yes, the AI poem most liked in the AI poetry study is horrible slop, and I don’t think you need problematic assumptions to explain why, it’s generic slop with no there there, it’s not particular, it doesn’t make interesting choices, it is just a series of cliche phrases, see, that’s it, I did it, no LLM consult required.)

And in other places, like the stuff Sarah Constantin is describing in Naming the Nameless (interesting historical note: Sarah did eventually leave the Bay, and I think she’s happier for it and that this essay is related to why), they are weaponizing a certain kind of aesthetics as a form of, essentially, fraud and associative vibe-based marketing and attempt to control people’s perceptions of things like ‘cool’ in ways that falsify their true preferences, for reasons political, personal and commercial. And they are attempting to attack us with the resulting paradox spirits when we try to call them out on this. Yes.

I also think there’s an implicit claim that if you are in good enough taste, enough ‘part of a project,’ then you don’t have to be accessible, you don’t have to stand outside the ‘project,’ and you don’t have to have aesthetic or other value absent your place in that project.

I think that’s very wrong. Doing all of that is also part of your job as an artist and creator. You can sacrifice it in some situations, and certainly you shouldn’t always be able to come in ‘in the middle’ of everything, but this very much counts against you, and reduces not only the reach of the work but also its value even to those who can handle it, because you’re operating without key constraints and that too is important context – you now owe us a worthwhile payoff.

As a writer, I have to continuously strike the balance of accessibility versus repetition, of knowing people don’t read these posts in any particular order. I make trade-offs that I’m learning to improve over time, and everyone else has to make them as well.

This concept seems important:

If you pay close attention to how your own taste operates, you can sometimes catch yourself deciding to like a thing. Sometimes this is because your friends like it, or some cool person you want to impress likes it. But other times it’s because part of you, a good part, a part you trust, recognizes something in the thing, a missing piece for a new person you are in the process of becoming.

You say to yourself “I want to like this thing because it is the kind of thing that the kind of person I want to be likes”. And you put yourself in the right posture to like the thing, build the necessary literacy, make the ritual gestures. But you can’t make yourself like something. Often, your existing preferences, as they already are, stubbornly refuse to budge. And sometimes they don’t.

If you pay close attention to this process, you will eventually see this as the terrain of artistic taste.

Weird to say ‘catch yourself’ as if it’s something to avoid or be ashamed about. I attempt to like things all the time. Ceteris paribus, I would prefer to like as many things (and people!) as possible, while keeping them in proper rank order. Find the good in it. But you don’t want to engage in preference falsification. You don’t want to pretend, especially to yourself, to like things you don’t like or especially things you despise, because you’re ‘supposed’ to like them, or it would benefit you to like them.

I went far enough down the rabbit hole to find this:

Frank Lantz: Wow, I just realized that in the comments to that post, Zvi actually makes the following comment: “The post is explaining why she and an entire culture is being defrauded by aesthetics. That is it used to justify all sorts of things, including high prices and what is cool, based on things that have no underlying value.”

So this attitude I thought was more implicit is actually a deliberate, considered position. I find that kind of exciting, honestly. How would I go about convincing Zvi to change his mind on this question?

In turn, I love Lantz’s attitude here that he finds this exciting, and it’s a lot of why I’m giving him so much consideration.

I presume this post should provide a lot of information on how one might go about convincing Zvi to change his mind on this, and what exactly it is that you might want to change my mind about?

Convince me, essentially, that there is a worthwhile and Platonic there there.

If Lantz wants to take a crack at convincing me, maybe even in person in NYC (and potentially even literally at MoMa), I’d be down, on the theory that given story value it’s hard for that to be an unsuccessful failure.

After decades of talk, Seagate seems ready to actually drop the HAMR hard drives

How do you fit 32 terabytes of storage into a hard drive? With a HAMR.

Seagate has been experimenting with heat-assisted magnetic recording, or HAMR, since at least 2002. The firm has occasionally popped up to offer a demonstration or make yet another “around the corner” pronouncement. The press has enjoyed myriad chances to celebrate the wordplay of Stanley Kirk Burrell, but new qualification from large-scale customers might mean HAMR drives will be actually available, to buy, as physical objects, for anyone who can afford the most magnetic space possible. Third decade’s the charm, perhaps.

HAMR works on the principle that, when heated, a disk’s magnetic materials can hold more data in smaller spaces, such that you can fit more overall data on the drive. It’s not just putting a tiny hot plate inside an HDD chassis; as Seagate explains in its technical paper, “the entire process—heating, writing, and cooling—takes less than 1 nanosecond.” Getting from a physics concept to an actual drive involved adding a laser diode to the drive head, optical steering, firmware alterations, and “a million other little things that engineers spent countless hours developing.” Seagate has a lot more about Mozaic 3+ on its site.

Seagate’s rendering of how its unique heating laser head allows for 3TB per magnetic platter in Mozaic drives.

Drives based on Seagate’s Mozaic 3+ platform, in standard drive sizes, will soon arrive with wider availability than its initial test batches. The driver maker put in a financial filing earlier this month (PDF) that it had completed qualification testing with several large-volume customers, including “a leading cloud service provider,” akin to Amazon Web Services, Google Cloud, or the like. Volume shipments are likely soon to follow.

big-loss-for-isps-as-supreme-court-won’t-hear-challenge-to-$15-broadband-law

Big loss for ISPs as Supreme Court won’t hear challenge to $15 broadband law

The Supreme Court petition was filed by the New York State Telecommunications Association, CTIA-The Wireless Association, NTCA-The Rural Broadband Association, USTelecom, ACA Connects-America’s Communications Association, and the Satellite Broadcasting and Communications Association. Cable lobby group NCTA filed a brief supporting the petition.

New York Attorney General Letitia James defended the state law in a Supreme Court brief filed in October. The brief said that when New York enacted its law, the Pai-era FCC “had classified broadband as an information service subject to Title I of the Communications Act. Under Title I, Congress gave the FCC only limited regulatory authority—leaving ample room for States to regulate information services.”

Multiple appeals courts have found “that federal law does not broadly preempt state regulations of Title I information services,” and “Congress has expressed no intent—much less the requisite clear and manifest intent—to preempt state regulation of Title I information services,” the New York brief said. “Applicants’ field preemption claim fails because, far from imposing a pervasive federal regulatory regime on Title I information services, Congress instead gave the FCC only limited authority over information services. Congress thus left the States’ traditional police powers over information services largely untouched.”

Law requires $15 price, or $20 for higher speeds

It’s unclear when New York might start enforcing its law. The state law was approved in 2021 and required ISPs to offer $15 broadband plans with download speeds of at least 25Mbps, with the $15 being “inclusive of any recurring taxes and fees such as recurring rental fees for service provider equipment required to obtain broadband service and usage fees.”

The law also said ISPs could instead choose to comply by offering $20-per-month service with 200Mbps speeds. Price increases would be capped at 2 percent per year, and state officials would periodically review whether minimum required speeds should be raised.

Residents who meet income eligibility requirements would qualify for the plans. ISPs with 20,000 or fewer subscribers would be allowed to apply for exemptions from the law.

The New York attorney general’s Supreme Court brief argued that public-interest factors “weigh heavily in favor of allowing” the law, and that it won’t create the economic problems that telco groups warned of. “The three largest broadband providers in New York are already offering an affordable broadband product to low-income consumers irrespective of the ABA, and smaller broadband providers can seek an exemption from the ABA’s requirements,” the brief said.

Huge math error corrected in black plastic study; authors say it doesn’t matter

Ars has reached out to the lead author, Megan Liu, but has not received a response. Liu works for the environmental health advocacy group Toxic-Free Future, which led the study.

The study highlighted that flame retardants used in plastic electronics may, in some instances, be recycled into household items.

“Companies continue to use toxic flame retardants in plastic electronics, and that’s resulting in unexpected and unnecessary toxic exposures,” Liu said in a press release from October. “These cancer-causing chemicals shouldn’t be used to begin with, but with recycling, they are entering our environment and our homes in more ways than one. The high levels we found are concerning.”

BDE-209, aka decabromodiphenyl ether or deca-BDE, was a dominant component of TV and computer housings before it was banned by the European Union in 2006 and some US states in 2007. China only began restricting BDE-209 in 2023. The flame retardant is linked to carcinogenicity, endocrine disruption, neurotoxicity, and reproductive harm.

Uncommon contaminant

The presence of such toxic compounds in household items is important for noting the potential hazards in the plastic waste stream. However, in addition to finding levels that were an order of magnitude below safe limits, the study also suggested that the contamination is not very common.

The study examined 203 black plastic household products, including 109 kitchen utensils, 36 toys, 30 hair accessories, and 28 food serviceware products. Of those 203 products, only 20 (10 percent) had any bromine-containing compounds at levels that might indicate contamination from bromine-based flame retardants, like BDE-209. Of the 109 kitchen utensils tested, only nine (8 percent) contained concerning bromine levels.

“[A] minority of black plastic products are contaminated at levels >50 ppm [bromine],” the study states.

But that’s just bromine compounds. Overall, only 14 of the 203 products contained BDE-209 specifically.

The product that contained the highest level of bromine compounds was a disposable sushi tray at 18,600 ppm. Given that heating is a significant contributor to chemical leaching, it’s unclear what exposure risk the sushi tray poses. Of the 28 food serviceware products assessed in the study, the sushi tray was only one of two found to contain bromine compounds. The other was a fast food tray that was at the threshold of contamination with 51 ppm.

F1 Arcade trip report: Great sims make for a compelling experience

Formula 1’s recent popularity still feels a little strange to longtime fans of the sport, particularly in the US, where it had been so niche for so long. But the past five years have seen F1 rise meteorically, and a new, much younger fanbase infused with enthusiasm for the cutting-edge race cars and the athletes who pilot them has emerged. F1 Arcade capitalizes on that popularity, combining food and drinks—including Lewis Hamilton’s agave tipple—with dozens and dozens of race simulators that let you race against friends or compete in teams against others.

With Washington, DC, chosen for F1 Arcade’s second US location, I obviously had to go check it out.

My first visit to the arcade in DC’s Union Market district was several weeks ago at the launch party, an affair that was packed with influencers and loud music. But I returned earlier this week, having booked a 45-minute, five-race session playing head-to-head against a friend. Prices vary depending on the number of races and whether you’re that at peak time, starting at $22/player for three races off-peak and going up to $42/player for five races at peak time. There’s no charge for people who are just spectating (or eating and drinking), not racing.

Perhaps surprisingly, the sims—which use hardware from Vesaro—don’t run the official Codemasters’ F1 game but instead a custom version of rFactor2 made by Motorsport Games for F1 Arcade, a title that’s notorious for being hard to master.

F1 Arcade’s CTO Gavin Williams thinks back to 2021. “There were a lot of things that weren’t quite right with the game,” he told me. “We actually went to Vesaro, who manufactured the simulators. We tried it, and literally none of us could race. It was just so unbearable to watch, and there were things that were missing, like the racing line, the skill settings weren’t quite right.”

americans-spend-more-years-being-unhealthy-than-people-in-any-other-country

Americans spend more years being unhealthy than people in any other country

For the new study, researchers at the Mayo Clinic analyzed health statistics collected by the World Health Organization. The resource included data from 183 countries, allowing the researchers to compare countries’ life expectancy and healthspans, which are calculated by years of life weighted by health status.

Longer, but not better

Overall, the researchers saw lifespan-healthspan gaps grow around the world, with the average gap rising from 8.5 years in 2000 to 9.6 years in 2019. Global life expectancy rose 6.5 years, to about 73 years, while healthspans only rose 5.4 years in that time, to around 63 years.

But the US was a notable outlier, with its gap growing from 10.9 years to 12.4 years, a 29 percent higher gap than the global mean.

The gap was most notable for women—a trend seen around the world. Between 2000 and 2019, US women saw their life expectancy rise 1.5 years, from 79.2 to 80.7 years, but they saw no change in their healthspans. Women’s lifespan-healthspan gap rose from 12.2 years to 13.7 years. For US men, life expectancy rose 2.2 years, from 74.1 to 76.3 years, and their healthspans also increased 0.6 years. Their lifespan-healthspan gap in 2019 was 11.1 years, 2.6 years shorter than women’s.

The conditions most responsible for US disease burden included mental and substance use disorders, plus musculoskeletal diseases. For women, the biggest contributors were musculoskeletal, genitourinary, and neurological diseases.

While the US presented the most extreme example, the researchers note that the global trends seem to present a “disease paradox whereby reduced acute mortality exposes survivors to an increased burden of chronic disease.”

Virgin Galactic studies Italian spaceport. The US-based suborbital space tourism company said Thursday it has signed an “agreement of cooperation” with Italy’s civil aviation authority to study the feasibility of Virgin Galactic conducting spaceflight operations from Grottaglie Spaceport in the Puglia region of Southern Italy. Phase one of the study, anticipated to be completed in 2025, will examine Grottaglie’s airspace compatibility with Virgin Galactic’s requirements and unique flight profile.

Follows earlier flight … The announcement comes 18 months after members of the Italian Air Force and the National Research Council of Italy conducted research aboard Virgin Galactic’s June 2023 ‘Galactic 01’ mission from Spaceport America in New Mexico. The flight marked the company’s first commercial spaceflight. It’s all well and good to be making such strategic announcements, but this is all dependent upon the company delivering on its new generation of Delta-class spaceships.

For some reason, Avio and MaiaSpace may partner. MaiaSpace CEO Johann Leroy has suggested that a partnership with Italian rocket-builder Avio could benefit both companies and bolster Europe’s independent access to space, European Spaceflight reports. “The goal of MaiaSpace is to design, produce, and operate the mini-launcher, as well as to market the related launch services, and to stay focused and responsive to market developments,” said Leroy. “However, I am convinced that a collaboration between Avio and MaiaSpace could be established. It would be an advantage for both companies and for Europe.”

But it’s not clear why … Founded in early 2022 as a wholly-owned subsidiary of ArianeGroup, MaiaSpace is developing a 50-meter tall, two-stage, partially reusable rocket designed to deliver small satellites to orbit. Avio builds solid rocket motors and is best known for its Vega rockets. It’s not clear why a reusable launch company would want to partner with a company that builds solids, which are not reusable.

Australian space center shuts down. A spaceport in the Northern Territory of Australia will cease operations immediately, the Australian Broadcast Corporation reports. The company running the spaceport, Equatorial Launch Australia, said it was now in conversations with the Queensland government to relocate its operations to Cape York. The space center’s claim to fame was the 2022 launch of three NASA sounding rockets from the facility.

Disagreements over territory … The company, Equatorial Launch Australia, had been planning a major expansion of the Arnhem Space Centre at its East Arnhem Land location. However that process apparently got bogged down, and the spaceport company blamed the delays on the Northern Land Council. This council pushed back and described those claims as a “falsehood.” The wait for a renewal of orbital launches from Down Under continues. (submitted by Marzipan)

Ukrainian launch company finds refuge in Maine. Promin Aerospace, a small launch company from Dnipro, Ukraine, opened its doors in Maine this month with a goal of hiring US engineers to complete development of its first rocket in time for a test launch in mid-2026, Payload reports. Promin’s goal of launching Ukraine’s first rocket from the coast of the Black Sea was put on hold after Russia invaded the country in February 2022.

Lobsters and launches … For the past two and a half years, Promin has been developing its unique rocket technology amid power outages, Internet connectivity problems, and sporadic attacks on Dnipro from Russian forces. The search started in Europe but quickly moved across the pond to take advantage of the speed and resources that US industry provides. “[Europe moves] very slow, so a lot of things that we expected would be done by our partners in 2022, they’re only going to be done in 2025,” said Misha Rudominski, Promin’s co-founder and CEO. The Maine Space Corporation was more welcoming. (submitted by Ken the Bin)

Long March-8A rocket set for debut. After successfully completing a wet dress rehearsal and other pre-launch tests, the first Long March-8A rocket is set for its debut launch in January 2025, China’s state-run news service, Xinhua, reports. The news service adds that the rocket is “designed to serve as China’s future primary launch vehicle for medium- and low-Earth orbit missions.” The rocket is capable of lofting up to 7 metric tons to a 700-km Sun-synchronous orbit.

Satellite workhorse … The newer rocket offers increased performance over the Long March 8 rocket and a larger 5.2-meter payload fairing. As such, it is being counted on to help deploy one or more of China’s planned satellite Internet megaconstellations. “The Long March-8A is an upgraded version of the Long March-8 rocket, specifically developed to meet the launch requirements of large-scale constellation networks in medium- and low-Earth orbits,” said Song Zhengyu, chief designer of the Long March-8 rocket.

Chinese national arrested after flying drone near SpaceX pad. Federal police arrested Yinpiao Zhou on Monday after he was allegedly caught flying a drone over the Vandenberg Space Force Base in California, The Telegraph reports. In a criminal complaint, the US Attorney’s Office said Zhou flew a drone over the base and took photographs on November 30, the same day a Falcon 9 rocket launched a payload on behalf of the National Reconnaissance Office. He has been accused of violating national defense air space and of failing to register an aircraft as required under US law.

Is that a drone in your pocket? … The complaint against Zhou, filed in California, says he admitted to installing software on his drone to evade limits on the height the device could fly at, and over a virtual fence around the Vandenberg base. The drone was allegedly in the air for 59 minutes and took photographs of SpaceX rocket pads and other sensitive areas. The flight was picked up by the base’s security team, who traced Zhou to nearby Ocean Park, where he was standing with another man. After initially hiding the drone in his coat, Zhou admitted he had flown it over the base.

Blue Origin says New Glenn is ready. Blue Origin said Tuesday that the test payload for the first launch of its new rocket, New Glenn, is ready for liftoff, Ars reports. The company published an image of the “Blue Ring” pathfinder nestled up against one half of the rocket’s payload fairing. This week’s announcement—historically Blue Origin has been tight-lipped about new products but is opening up more as it nears the debut of its flagship New Glenn rocket—appears to serve a couple of purposes.

Still targeting 2024 for liftoff … First of all, the relatively small payload contrasted with the size of the payload fairing highlights the greater volume the rocket offers over most conventional boosters. Additionally, the company appears to be publicly signaling the Federal Aviation Administration and other regulatory agencies that it believes New Glenn is ready to fly, pending approval to conduct a hot-fire test at Launch Complex-36, and then for a liftoff from Florida. This is a not-so-subtle message to regulators to please hurry up and complete the paperwork necessary for launch activities. A company official said the plan remains to launch New Glenn before the end of 2024.

SpaceX static-fires booster for next Starship flight. Only three weeks after Flight 6, SpaceX has static-fired Booster 14 and rolled Ship 33 to Masseys to complete its own engine testing, NASASpaceflight.com reports. Once both vehicles are tested, SpaceX will begin the final drive to Flight 7, potentially launching in January. Booster 14 is more or less identical to Booster 13 on the outside except for the ship engine chill pipe extensions on previous boosters. These are no longer needed, as Block 2 of the ship has its engine chill pipes running through the aft flap fairing with a flare outward at the bottom. This simplifies the connection between the ship and the booster and reduces mass.

Block 2 upgrades … Ship 33 has many changes compared to past ships, as it is the first Block 2 ship. First and foremost for Block 2 are the extended propellant tanks. SpaceX added a ring on the ship, making it 21 rings tall, and moved around the common and forward domes to be able to load 300 more tons of propellant into the ship. This addition will allow SpaceX to increase its payload to orbit with Block 2. The sacrifice was a smaller payload bay section, which went from five rings to three rings. However, SpaceX retained most of its usable payload space, as the nose cone on Block 2 was completely redesigned. (submitted by Ken the Bin)

ULA expects to be certified for national security launch soon. United Launch Alliance expects to gain Space Force certification for national security payloads within a few months, company chief executive Tory Bruno told Breaking Defense. He added that no further testing of the Vulcan Centaur will be needed to meet certification, saying the company has met all the requirements from the Pentagon. Two successful launches are requisite to achieve certification for carrying payloads under the Space Force’s National Security Space Launch program.

Seeking a higher cadence … A January launch was deemed a success, but there was an anomaly during the second flight in October with one of Vulcan’s solid rocket boosters that currently is under investigation. Overall, he said, the company has 20 launches manifested for 2025, with 16 Vulcan rockets stored away for use and no worries that production won’t be able to keep up with demand. Looking forward, Bruno said he hopes to have 20-30 Vulcan launches a year, about “half” of which would be for national security. (submitted by Ken the Bin)

Super heavy lift is ‘essential’ to Europe. This week the European Space Agency has published a third iteration of a proposed pathfinder study for the development of a European reusable super heavy-lift rocket capable of delivering 60 metric tons to low-Earth orbit, European Spaceflight reports. Twice before, in November and early December, the space agency published and then deleted a call for a study. While the first and second iterations made no mention of Ariane 6, currently Europe’s only heavy-lift rocket, the third iteration highlights the limitations of the ArianeGroup-built rocket.

A final decision may come next year … The text states that the development of a “European very-heavy launch system” is essential for Europe’s future ambitions in space and represents a necessary step to ensure the continent remains competitive in the global launch market. Once the study is complete, ESA hopes to have a detailed end-to-end development roadmap with a well-defined business case that could be used to move forward with the project quickly. A decision on whether to adopt the program will likely be made at the ESA ministerial meeting in late 2025. (submitted by Ken the Bin)

Are LLMs capable of non-verbal reasoning?

In the researchers’ COCONUT model (for Chain Of CONtinUous Thought), those kinds of hidden states are encoded as “latent thoughts” that replace the individual written steps in a logical sequence both during training and when processing a query. This avoids the need to convert to and from natural language for each step and “frees the reasoning from being within the language space,” the researchers write, leading to an optimized reasoning path that they term a “continuous thought.”

Being more breadth-minded

While doing logical processing in the latent space has some benefits for model efficiency, the more important finding is that this kind of model can “encode multiple potential next steps simultaneously.” Rather than having to pursue individual logical options fully and one by one (in a “greedy” sort of process), staying in the “latent space” allows for a kind of instant backtracking that the researchers compare to a breadth-first-search through a graph.

This emergent, simultaneous processing property comes through in testing even though the model isn’t explicitly trained to do so, the researchers write. “While the model may not initially make the correct decision, it can maintain many possible options within the continuous thoughts and progressively eliminate incorrect paths through reasoning, guided by some implicit value functions,” they write.

That kind of multi-path reasoning didn’t really improve COCONUT’s accuracy over traditional chain-of-thought models on relatively straightforward tests of math reasoning (GSM8K) or general reasoning (ProntoQA). But the researchers found the model did comparatively well on a randomly generated set of ProntoQA-style queries involving complex and winding sets of logical conditions (e.g., “every apple is a fruit, every fruit is food, etc.”)

For these tasks, standard chain-of-thought reasoning models would often get stuck down dead-end paths of inference or even hallucinate completely made-up rules when trying to resolve the logical chain. Previous research has also shown that the “verbalized” logical steps output by these chain-of-thought models “may actually utilize a different latent reasoning process” than the one being shared.

This new research joins a growing body of research looking to understand and exploit the way large language models work at the level of their underlying neural networks. And while that kind of research hasn’t led to a huge breakthrough just yet, the researchers conclude that models pre-trained with these kinds of “continuous thoughts” from the get-go could “enable models to generalize more effectively across a wider range of reasoning scenarios.”

Character.AI steps up teen safety after bots allegedly caused suicide, self-harm

Following a pair of lawsuits alleging that chatbots caused a teen boy’s suicide, groomed a 9-year-old girl, and caused a vulnerable teen to self-harm, Character.AI (C.AI) has announced a separate model just for teens, ages 13 and up, that’s supposed to make their experiences with bots safer.

In a blog, C.AI said it took a month to develop the teen model, with the goal of guiding the existing model “away from certain responses or interactions, reducing the likelihood of users encountering, or prompting the model to return, sensitive or suggestive content.”

C.AI said “evolving the model experience” to reduce the likelihood kids are engaging in harmful chats—including bots allegedly teaching a teen with high-functioning autism to self-harm and delivering inappropriate adult content to all kids whose families are suing—it had to tweak both model inputs and outputs.

To stop chatbots from initiating and responding to harmful dialogs, C.AI added classifiers that should help C.AI identify and filter out sensitive content from outputs. And to prevent kids from pushing bots to discuss sensitive topics, C.AI said that it had improved “detection, response, and intervention related to inputs from all users.” That ideally includes blocking any sensitive content from appearing in the chat.

Perhaps most significantly, C.AI will now link kids to resources if they try to discuss suicide or self-harm, which C.AI had not done previously, frustrating parents suing who argue this common practice for social media platforms should extend to chatbots.

Other teen safety features

In addition to creating the model just for teens, C.AI announced other safety features, including more robust parental controls rolling out early next year. Those controls would allow parents to track how much time kids are spending on C.AI and which bots they’re interacting with most frequently, the blog said.

C.AI will also be notifying teens when they’ve spent an hour on the platform, which could help prevent kids from becoming addicted to the app, as parents suing have alleged. In one case, parents had to lock their son’s iPad in a safe to keep him from using the app after bots allegedly repeatedly encouraged him to self-harm and even suggested murdering his parents. That teen has vowed to start using the app whenever he next has access, while parents fear the bots’ seeming influence may continue causing harm if he follows through on threats to run away.

Report: AT&T, Verizon aren’t notifying most victims of Chinese call-records hack

Telecom companies aren’t required to notify customers about every breach. A Federal Communications Commission order in December 2023 adopted a “harm-based notification trigger” in which “notification of a breach to consumers is not required in cases where a carrier can reasonably determine that no harm to customers is reasonably likely to occur as a result of the breach, or where the breach solely involves encrypted data and the carrier has definitive evidence that the encryption key was not also accessed, used, or disclosed.”

The FCC said that harm requiring notifications can include, but is not limited to, “financial harm, physical harm, identity theft, theft of services, potential for blackmail, the disclosure of private facts, the disclosure of contact information for victims of abuse, and other similar types of dangers.”

The FCC order argued that the harm-based standard would let carriers “focus their time, effort, and financial resources on the most important and potentially harmful incidents” and protect “customers from over-notification and notice fatigue, specifically in instances where the carrier has reasonably determined that no harm is likely to occur.”

Senator: Telecoms should tell customers

US Sen. Ron Wyden (D-Ore.) this week criticized the carriers for having weak security and the FCC for “let[ting] phone companies write their own cybersecurity rules.” Wyden proposed legislation to beef up telecom security requirements.

A spokesperson for Wyden today said that carriers should notify the affected customers.

“Senator Wyden strongly supports the phone companies notifying their customers about the theft of their data,” the spokesperson told Ars. “Not only do Americans have a right to be told that their information was stolen, but this is useful information that could result in some consumers voting with their wallets and switching service to carriers that retain less data and or have better cybersecurity.”

Stanford University researchers collected and studied telephone metadata for a 2016 paper to determine how it could be used against customers. “Using crowdsourced telephone logs and social networking information, we find that telephone metadata is densely interconnected, susceptible to reidentification, and enables highly sensitive inferences,” they wrote.
