Newly spotted black hole has mass of 17 billion Suns, adding another daily

Feeding frenzy —

An accretion disk 7 light-years across powers an exceptionally bright galaxy.

Quasars initially confused astronomers when they were discovered. First identified as sources of radio-frequency radiation, later observations showed that the objects had optical counterparts that looked like stars. But the spectrum of these ostensible stars showed lots of emissions at wavelengths that didn’t seem to correspond to any atoms we knew about.

Eventually, we figured out these were spectral lines of normal atoms but heavily redshifted by immense distances. This means that to appear like stars at these distances, these objects had to be brighter than an entire galaxy. Eventually, we discovered that quasars are the light produced by an actively feeding supermassive black hole at the center of a galaxy.

But finding new examples has remained difficult because, in most images, they continue to look just like stars—you still need to obtain a spectrum and figure out their distance to know you’re looking at a quasar. Because of that, there might be some unusual quasars we’ve ignored because we didn’t realize they were quasars. That’s the case with an object named J0529−4351, which turned out to be the brightest quasar we’ve ever observed.

That’s no star!

J0529−4351 had been observed a number of times, but its nature wasn’t recognized until a survey went hunting for quasars and recognized it was one. At the time of the 2023 paper that described the survey, the researchers behind it suggested that it had either been magnified through gravitational lensing, or it was the brightest quasar we’ve ever identified.

In this week’s Nature Astronomy, they confirmed: It’s not lensed, it really is that bright. Gravitational lensing tends to distort objects or create multiple images of them. But J0529−4351 is undistorted, and nothing nearby looks like it. And there’s nothing in the foreground that has enough mass to create a lens.

So, how do you take an instance of an incredibly bright object and make it even brighter? The light from a quasar is produced by an accretion disk. While accretion disks can form around black holes with masses similar to stars, quasars require a supermassive black hole like the ones found at the center of galaxies. These disks are formed of material that has been captured by the gravity of the black hole and is in orbit before falling inward and crossing the event horizon. Light is created as the material is heated by collisions of its constituent particles and gives up gravitational energy as it falls inward.

Getting more light out of an accretion disk is pretty simple: You either put more material in it or make it bigger. But there’s a limit to how much material you can cram into one. At some point, the accretion disk will produce so much radiation that it drives off any additional material that’s falling inward, essentially choking off its own food supply. Called the Eddington limit, this sets ceilings on how bright an accretion disk can be and how quickly a black hole can grow.

Factors like the mass of the black hole and its spin help set the Eddington limit. Plus, the amount of material falling inward can drop below the Eddington limit, leading to a bit less light being produced. Trying various combinations of these factors and checking them against observational data, the researchers came up with several estimates for the properties of the supermassive black hole and its accretion disk.

Extremely bright

For the supermassive black hole’s size, the researchers propose two possible estimates: one at 17 billion solar masses, and the other at 19 billion solar masses. That’s not the most massive one known, but there are only about a dozen thought to be larger. (For comparison, the one at the center of the Milky Way is “only” about 4 million solar masses.) The data is best fit by a moderate spin, with us viewing it from about 45 degrees off the pole of the black hole. The accretion disk would be roughly seven light-years across. Meaning, if the system were centered on our Sun, several nearby stars would be within the disk.

The accretion rate needed to power the brightness is just below the Eddington limit and works out to roughly 370 solar masses of material per year. Or, about a Sun a day. At that rate, it would take about 30 million years to double in size.

But it’s rare to have that much material around for one to feed that long. And a look through archival images shows that the brightness of J0529−4351 can vary by as much as 15 percent, so it’s not likely to be pushing the Eddington limit the entire time.

Even so, it’s difficult to understand how that much material can be driven into the center of a galaxy for any considerable length of time. The researchers suggest that the ALMA telescope array might be able to pick up anything unusual there. “If extreme quasars were caused by unusual host galaxy gas flows, ALMA should see this,” they write. “If nothing unusual was found in the host gas, then this would sharpen the well-known puzzle of how to sustain high accretion rates for long enough to form such extreme supermassive black holes.”

The whole accretion disk is also large enough that it should be possible to image it with the Very Large Telescope, which would allow us to track the disk’s rotation and estimate the black hole’s mass.

The system’s extreme nature, then, may actually help us figure out its details despite its immense distance. Meanwhile, the researchers wonder whether other unusual systems might remain undiscovered simply because we haven’t considered that an object might be a quasar instead of a star.

Darwin Online has virtually reassembled the naturalist’s personal library

“I have bought many books….” —

Previous catalogs only listed about 15 percent of the naturalist’s extensive collection.

State Darwin Museum, Moscow

Famed naturalist Charles Darwin amassed an impressive personal library over the course of his life, much of which was preserved and cataloged upon his death in 1882. But many other items were lost, including more ephemeral items like unbound volumes, pamphlets, journals, clippings, and so forth, often only vaguely referenced in Darwin’s own records.

For the last 18 years, the Darwin Online project has painstakingly scoured all manner of archival records to reassemble a complete catalog of Darwin’s personal library virtually. The project released its complete 300-page online catalog—consisting of 7,400 titles across 13,000 volumes, with links to electronic copies of the works—to mark Darwin’s 215th birthday on February 12.

“This unprecedentedly detailed view of Darwin’s complete library allows one to appreciate more than ever that he was not an isolated figure working alone but an expert of his time building on the sophisticated science and studies and other knowledge of thousands of people,” project leader John van Wyhe of the National University of Singapore said. “Indeed, the size and range of works in the library makes manifest the extraordinary extent of Darwin’s research into the work of others.”

Darwin was a notoriously voracious reader, and Down House was packed with books, scientific journals pamphlets, and magazine clippings that caught his interest. He primarily kept his personal library in his study: an “Old Study” and, after an 1877 addition to the west end of the house, a “New Study.” A former governess named Louise Buob described how Darwin’s books and papers inevitably spilled “into the hall and corridors, whose walls are covered with books.”

The French literary critic Francisque Sarcey remarked in 1880 that the walls of the New Study were concealed “top to bottom” with books, as well as two bookcases in the middle of the study—one filled with books, the other with scientific instruments. This was very much a working library, with well-worn and often tattered books, as opposed to fine leather-bound volumes designed for display. After Darwin died, an appraiser valued the scientific library at just 30 pounds (about 2,000 pounds today) and the entire collection of books at a mere 66 pounds (about 4,400 pounds today). Collectors now pay a good deal more for a single book that once belonged to Darwin.

The two main collections of Darwin’s books—amounting to some 1,480 titles—are housed at the University of Cambridge and Down House, respectively, but that number does not include the more ephemeral items referred to in Darwin’s own records. According to the folks at Darwin Online, tracking down every single obscure reference to a publication was a case study in diligent detective work since Darwin often only hurriedly jotted down a few notes, with crucial information like author, date, or even the source of a clipping often missing.

Many of these have now been identified for the first time. One of the project’s major sources was a handwritten 426-page compilation from 1875, whose abbreviated entries eventually yielded 440 previously unknown titles originally in Darwin’s library. They also scoured Darwin’s reading notebooks, Emma Darwin’s diaries, a 1908 catalog of books donated to Cambridge, and the Darwin Correspondence (30 volumes in all), as well as historic auction and rare book catalogs.

The newly discovered items in Darwin’s library include works by philosophers John Stuart Mill and Auguste Comte, as well as Charles Babbage and what was at the time a controversial book on gorillas: Paul du Chaillu’s Explorations and Adventures in Equatorial Africa. The naturalist also owned a copy of an 1826 article on the habits of the turkey buzzard by ornithologist John James Audubon. His personal library also included less heady fare, like a coffee table book of heliotrope illustrations, an 1832 road atlas of England and Wales, an 1852 treatise on investments, a book about chess, an illustrated 1821 book on the Nomenclature of Colours, and a book on the “water cure” for chronic disease. (Darwin was a devotee of the water cure—not to be confused with the method of torture—for his many ailments.)

As impressive as the Darwin Online catalog currently is, the project is still ongoing. “There can be no doubt that further works that belonged to Darwin and his family remain to be recorded here,” the folks at Darwin Online wrote, and the project welcomes any information that leads to those missing works.

Before snagging a chunk of space junk, Astroscale must first catch up to one

This artist's illustration released by Astroscale shows the ADRAS-J spacecraft (left) approaching the defunct upper stage from a Japanese H-IIA rocket.

Enlarge / This artist’s illustration released by Astroscale shows the ADRAS-J spacecraft (left) approaching the defunct upper stage from a Japanese H-IIA rocket.

Astroscale, a well-capitalized Japanese startup, is preparing a small satellite to do something that has never been done in space.

This new spacecraft, delivered into orbit Sunday by Rocket Lab, will approach a defunct upper stage from a Japanese H-IIA rocket that has been circling Earth for more than 15 years. Over the next few months, the satellite will try to move within arm’s reach of the rocket, taking pictures and performing complicated maneuvers to move around the bus-size H-IIA upper stage as it moves around the planet at nearly 5 miles per second (7.6 km/s).

These maneuvers are complex, but they’re nothing new for spacecraft visiting the International Space Station. Military satellites from the United States, Russia, and China also have capabilities for rendezvous and proximity operations (RPO), but as far as we know, these spacecraft have only maneuvered in ultra-close range around so-called “cooperative” objects designed to receive them.

The difference here is the H-IIA rocket is uncontrolled, likely spinning and in a slow tumble, and was never designed to accommodate any visitors. Japan left it in orbit in January 2009 following the launch of a climate monitoring satellite and didn’t look back.

That was the case, at least, until a few years ago, when the Japan Aerospace Exploration Agency (JAXA) partnered with Astroscale in a public-private partnership to demonstrate capabilities the private sector could use to eventually remove large pieces of space debris littering low-Earth orbit. The same robotic technologies could also apply to satellite servicing or refueling missions.

“We are putting this debris removal by robotic technology as one of our main technology development areas because safely approaching an object, and also observing the object and capturing the object, is basically a common technology for any on-orbit servicing,” said Eddie Kato, president and managing director of Astroscale Japan.

In hot pursuit

This mission is called ADRAS-J, short for Active Debris Removal by Astroscale-Japan. “This mission entails the first ever approach of actual space debris and will be a monumental step toward a more sustainable future in space,” Mike Lindsay, Astroscale’s chief technology officer, posted on X.

The ADRAS-J spacecraft, built in-house at Astroscale’s Tokyo headquarters, is about the size of a kitchen oven and weighs roughly 330 pounds (150 kilograms) fully fueled. The satellite launched from New Zealand at 9: 52 am EST (1452 UTC) Sunday aboard an Electron rocket provided by Rocket Lab. About an hour after liftoff, ADRAS-J deployed from the Electron’s kick stage into an on-target polar orbit reaching an altitude of 370 miles (600 kilometers) at its highest point.

The liftoff from Rocket Lab’s spaceport in New Zealand was timed to allow ADRAS-J to launch into the same orbital plane as its objective—the H-IIA upper stage. Astroscale reported the spacecraft was healthy after Sunday’s launch. In a pre-launch interview, Kato said ADRAS-J will begin its pursuit of the spent H-IIA rocket in a couple of weeks, once ground teams complete initial checkouts of the spacecraft.

ADRAS-J will fire thrusters to match orbits with the H-IIA rocket, and as soon as next month, it could be flying within about 300 feet (100 meters) of the abandoned upper stage. Astroscale engineers will initially rely on ground-based tracking data to pinpoint the H-IIA’s location in space. Once in closer range, ADRAS-J will use visible and infrared cameras, along with laser ranging sensors, to transition to relative navigation mode. These sensors will measure the distance, closing rate, and orientation of the upper stage.

Astroscale officials view the switch from relying on ground tracking data to onboard relative navigation sensors as a crucial moment for the ADRAS-J mission. ADRAS-J will circle the rocket to assess its spin rate, spin axis, and the condition of its structure. This is the crux of the challenge for ADRAS-J because the rocket is unpowered and therefore unable to hold position. The upper stage also lacks laser reflectors and targets that would aid an approaching spacecraft.

This will mark the conclusion of the JAXA-supported portion of the ADRAS-J mission. If everything is working as planned, the spacecraft could move closer to the rocket to further validate Astroscale’s sensor suite and automated navigation and guidance algorithms. This will allow the company’s engineers to gather data for a proposed follow-on mission to actually go up and grab onto the same H-IIA upper stage and remove it from orbit.

“We are targeting to go closer, maybe 1 to 2 meters away from the object. Why? Because the next mission will be to really capture the H-IIA launch vehicle,” Kato told Ars last week. “In order to safely approach to a range where a robotic arm is able to be extended, it’s probably like 1.5 to 2 meters away from the object. We want to demonstrate up to that point through this ADRAS-J mission. Then on the next mission, called ADRAS-J2, we are actually equipping the robotic arm and capturing the H-IIA launch vehicle.”

Will Smith parodies viral AI-generated video by actually eating spaghetti

Mangia, mangia —

Actor pokes fun at 2023 AI video by eating spaghetti messily and claiming it’s AI-generated.

The real Will Smith eating spaghetti, parodying an AI-generated video from 2023.

Enlarge / The real Will Smith eating spaghetti, parodying an AI-generated video from 2023.

On Monday, Will Smith posted a video on his official Instagram feed that parodied an AI-generated video of the actor eating spaghetti that went viral last year. With the recent announcement of OpenAI’s Sora video synthesis model, many people have noted the dramatic jump in AI-video quality over the past year compared to the infamous spaghetti video. Smith’s new video plays on that comparison by showing the actual actor eating spaghetti in a comical fashion and claiming that it is AI-generated.

Captioned “This is getting out of hand!”, the Instagram video uses a split screen layout to show the original AI-generated spaghetti video created by a Reddit user named “chaindrop” in March 2023 on the top, labeled with the subtitle “AI Video 1 year ago.” Below that, in a box titled “AI Video Now,” the real Smith shows 11 video segments of himself actually eating spaghetti by slurping it up while shaking his head, pouring it into his mouth with his fingers, and even nibbling on a friend’s hair. 2006’s Snap Yo Fingers by Lil Jon plays in the background.

In the Instagram comments section, some people expressed confusion about the new (non-AI) video, saying, “I’m still in doubt if second video was also made by AI or not.” In a reply, someone else wrote, “Boomers are gonna loose [sic] this one. Second one is clearly him making a joke but I wouldn’t doubt it in a couple months time it will get like that.”

We have not yet seen a model with the capability of Sora attempt to create a new Will-Smith-eating-spaghetti AI video, but the result would likely be far better than what we saw last year, even if it contained obvious glitches. Given how things are progressing, we wouldn’t be surprised if by 2025, video synthesis AI models can replicate the parody video created by Smith himself.

It’s worth noting for history’s sake that despite the comparison, the video of Will Smith eating spaghetti did not represent the state of the art in text-to-video synthesis at the time of its creation in March 2023 (that title would likely apply to Runway’s Gen-2, which was then in closed testing). However, the spaghetti video was reasonably advanced for open weights models at the time, having used the ModelScope AI model. More capable video synthesis models had already been released at that time, but due to the humorous cultural reference, it’s arguably more fun to compare today’s AI video synthesis to Will Smith grotesquely eating spaghetti than to teddy bears washing dishes.

Monthly Roundup #15: February 2024

Another month. More things. Much roundup.

Jesse Smith writes in Asterisk that our HVAC workforce is both deeply incompetent and deeply corrupt. This certainly matches my own experience. Calculations are almost always flubbed when they are done at all, outright fraudulent paperwork is standard, no one has the necessary skills.

It certainly seems like the Biden Administration is doing its best to hurt Elon Musk? Claim here is that they cancelled a Starlink contract without justification, in order to award the contract to someone else for more than three times the price. This was on Twitter, but none of the replies seemed to offer a plausible justification.

Claim that Twitter traffic is increasingly fake, and secondary claim that this is because Musk fired those responsible for preventing it. Even if it is true that Twitter traffic is 75% fake, that does not mean that your experience will be 75% bots, or even 7.5% bots. Mine is more like 0.75%. As usual, the bots are mostly making zero attempt to not look like bots, and would be trivial to find and ban if people cared.

Nate Silver is correct that ‘misinformation experts’ are collectively making a mistake when they themselves spread highly partisan misinformation, and also that the game theory makes it impossible for them to collectively stop.

The word ‘genocide’ risks being watered down to the point where we will not have a word for what it used to mean, and this will make it much harder to maintain the taboo of Never Again.

Avatar: The Last Airbender’s live action Netflix version decides that some of the scenes in the original ‘are iffy’ and it needs to soften a cartoon show made for eight year olds, to exclude a character arc where a boy grows up and learns not to be sexist, because the character started off too sexist. Not that I was ever watching anyway. As one commenter notes, if that is an issue, in news related to the previous item, wait until you hear about the Fire Nation.

An essay correctly identifying some (but far from all) of the problems with modern (post-2017) Star Trek, and how things have shifted from Starfleet being fundamentally good and its officers as professionals committed to behaving as such and living up to its ideals, to Starfleet being more often than not the enemy institution to be critiqued and opposed morally and practically, although its rivals are still worse, and everyone standing up for personal morality and vibes rather than caring about principles, professionalism, discipline or truth.

Picard I see as doing this ‘on purpose’ as subject, while still embodying the ideals of old Star Trek and thus still being actual Star Trek, Picard falls back upon moral authority because this is a scenario in which he lacks chain of command, whereas Discovery is simply a distinct entity (also its imagined future pretty much ruins everything) and thus I do not treat it as canon.

(Strange New Worlds a lot of people I know think is great, but both I and my wife stuck with it for that reason and found it unwatchable and bad on pure quality grounds, the issues pointed at here didn’t seem to be the problem.)

More on the lying, cheating bathroom scales that have been imbued with memory. A vision of one form of nightmare awaiting us in a future full of things that have ‘intelligence.’ Good news is the replacement scale I bought lacks this ‘feature.’

Claim that the remote work is devastating to talent development in software engineers. As someone who has worked from home most of their various careers I am skeptical. Yes, I see the value of in-person contact for tech, but it would be so easy to also make the opposite case.

Another case against smartphones, this one that they obviate and eliminate the opportunities and finitudes in which those virtues are cultivated. And yes, ‘your pocket calculator’ and everyone else’s can radically alter dynamics to derail many who would otherwise be likely to accomplish great things. It is amazing that those terrified of the slightest regulation as the death of innovation will often deny that any other obstacle in someone worthy’s path could ever stop them. You can’t have it both ways.

To what extent is our continuing to cook our own food a regulatory issue? To what extent is it us not actually being all that rich?

I do not think it is lack of wealth. Cooking for yourself is not even obviously more efficient, since you give up mass production. The places that most economize on food, such as schools and armies and collectivist groups, very much do not have anyone cooking for themselves. Cooking for yourself can be a luxury. You get food exactly how you want it, when you want it, fresh and not (do not underestimate fresh and hot) and you get to do something many people enjoy and find rewarding. This does break at the extremes, but that is a long way from where we are, and the very fact we are rich makes the labor required expensive. Being richer won’t save you from cost disease.

So how much does the regulatory issue matter? What would happen if we did not charge extra taxes when food production was outsourced, as opposed to the current method where groceries are immune from taxation and also your labor preparing them is not taxed? What if we also allowed things like small-batch sales from whoever wanted to cook something that day, and enabled that marketplace to properly clear? How much would we then rely on others more?

My guess is there would be substantial movement but less than you might anticipate. There are real natural advantages to cooking for yourself and your family. People rightfully take joy in cooking, and it has its benefits.

One might even say that there is a strange curve, where one starts out so poor one cannot cook, gets rich enough to cook, then gets rich enough to not cook, then rich enough to start cooking again, then perhaps rich enough to have a personal chef.

$250 an hour empty nest coaches for parents who can’t handle it? I mean, sure, I guess, shrinks cost what they cost. I love my kids but do not anticipate having this problem. Oh no, suddenly I have lots of space and money and time.

Extensive guides are being offered to the puzzle that is Disney World, where the stress, planning, time and money costs seem to be spiraling out of control. I have no doubt there is much genuine magic to be had underneath it all, but none of this seems like something any sane person would subject themselves to on purpose, unless you placed very high story value on it. I suppose this was inevitable. People are bidding against each other for the Disney World experience using various currencies, there are a lot of Americans and only one park, so only those who get unusually high value from it will find it worth the price. Seems like there is a lot of winner’s curse going on, also toxic dynamics involving the expectations of children, where the existence of the park is for most people a net negative whether or not they go.

Here is one good use case, showing giant reams of sheet music while playing piano.

Chris Velazco tries it out for the Washington Post. He concludes it has its uses, but that ultimately no you do not need it. The spacial computing as work plan continues to not look good at current margins versus using a desktop with multiple monitors.

Mark Zuckerberg strikes back, flat out calls Quest the better product even ignoring the price differential. Apple’s screen resolution is better, he says, but they had to make tons of compromises to get it, and for most purposes the Quest is better, because it is open and there is software for it and it supports more use cases and input devices.

Demos for the Quest were not available locally, but I tried one on and the difference in resolution was obvious right away.

Liron Shapira joins those returning their Vision Pro, as he was looking for productivity, and the mirroring DPI wasn’t good enough. He did find it promising otherwise as a relaxing work environment, and notes that ignoring his family can also be fun. I applaud him for running the experiment. He does note it might work for those who are already at lower resolutions due to poor vision.

Meanwhile reports are it will be at least 18 months before the second version is available.

Time is valuable and optionality is great. So it still simultaneously seems crazy to buy one, and also crazy to not buy one. I am leaning towards passing, but still not sure.

The problem in science.

helicopterosaur: In a randomized controlled experiment, even if the difference you’re measuring is not there, you can still get a statistically significant result if you roll a natural 20.

Ronny Fernandez: Of course, part of what’s sad here is that scientists tend to think of this as rolling a natural 20 rather than as rolling a natural 1.

Another problem in science is that prestigious journals are now sufficiently gated that publishing in them actively interferes with scientific work.

Ethan Mollick: Evidence that academic publishing is now doing the exact opposite of what it did before the internet. It is now a massive gatekeeper to knowledge, rather than a way of distributing it. Publishing in an expensive journal can lower, rather than raise, citation counts.

Florian Ederer: Market power hinders the dissemination of knowledge.

+1% increase in journal price ➡️ -0.83% article’s citations and -1.07% citing author count with much larger effect for citations from lower-ranked institutions.

Immediate boost to citations when an article becomes free on JSTOR.

Most economics papers and other academic work is useless, everyone involved knows this, outside of the top quartile it is essentially a grift where nothing would survive critical review. Tyler Cowen retweeted and I too have come around to thinking this is basically correct.

Also here we see that the statistical results of economics papers are so frequently selected, and so excessive in their results as compared to their statistical power, that a majority of them are at best misleading.

A large majority of empirical evidence reported in leading economics journals is potentially misleading. Results reported to be statistically significant are about as likely to be misleading as not (falsely positive) and statistically nonsignificant results are much more likely to be misleading (falsely negative). We also compare observational to experimental research and find that the quality of experimental economic evidence is notably higher.

I have done my best to be skeptical, both of each result and of academia in general.

It seems I need to up my game.

Technically bad news, the growth rate of EV sales has slowed? Everyone remember how exponentials work?

Those are growth rates, so the complaint is that we aren’t selling enough more than we were before in relative terms. Oh, no.

Lithium prices are declining once again.

Billionaires commit a lot of crime and fraud. That is how I would summarize the key findings of Ben West in Rates of Criminality Amongst Giving Pledge Signatories, where roughly 200 non-EA billionaires pledged to give most of their money away, and we find 25% have been accused of financial misconduct, 10% or so have been convicted of financial misconduct, 4% have spent some time in prison and 41% have at least one misconduct allegation against them.

It is of course possible that signing a pledge saying you will give all your money away correlates highly with willingness to do crime and be deceptive, for various reasons, along with the obvious reasons to suspect the opposite. My guess is this is representative.

My presumption is also that the rate of actually doing the crime vastly exceeds the rate of doing the time. Most crimes of almost all types are not punished, most perpetrators not caught let alone convicted. White collar crimes of billionaires seem unlikely to be an exception. You could say that they bring greater scrutiny and have more enemies. They also have much better tools to avoid consequences.

Why? My model says that the acts required to become a billionaire make you willing to engage in such conduct if you weren’t already, and those winning to engage in such conduct are much less likely to become billionaires. Also the world has a lot of fraud and crime in it. I still think it is important to draw the distinction between ‘ordinary decent fraud’ versus aggressive fraud versus outright fraud, and how much we expect of each one. As the post notes, our intuitions for such situations are often poor.

The discussion section is disappointingly mostly about how much to expect there to be scandals from those giving to charity, rather than learning important facts about the world.

I continue to have the point of view that if someone wants to donate their money to a good cause, that money should be used for the good cause.

I don’t get this either, and consider it evidence against the broader EMH that companies generally do reasonable things:

Gordo: there is no way it is good marketing practice for a company to email you 9 times within 2 days of purchasing a product how on earth are we justifying these actions.

There is no question in my mind that many companies massively over-email you when you buy their products. I presume this is a simple case of each email having clear benefits where sometimes people respond and buy something or give you traffic, and they impose costs on users that those users then punish you for gradually over time. In general, if something has this form, where you burn goodwill for benefits now, I expect massive overuse.

Political charitable donations and apolitical charitable donations are functional substitutes, increasing donations to the Red Cross in the wake of a natural disaster and increasing political donations in the wake of campaign adds come partly at each others’ expense. It seems odd to think that it would be otherwise. Do people forget that giving to politics is giving to charity? If you are familiar with Effective Altruism, you understand the core insight that a lot of charitable donations have zero or negative net impact, so there’s nothing weird here.

Rules for cults from Ben Landau-Taylor’s mother. If the group members are in contact with their families and people who don’t share the group’s ideology, and old members are welcome at parties, then proceed, you will be fine. If not, then no, do not proceed, you will likely not be fine.

I strongly agree with Sarah Constantin that the old school Patron model of ‘rich person decides to fund this and funds it’ model is highly underrated, including that it is very much working for me. There are major obvious flaws, you cannot fully systematize it and would not want to. But I love it because it lets everyone involved focus on what matters and actually do the valuable thing. You can create something far more valuable, or do much better scientific work, if you do not need to constantly be checking your incentives and dealing with various forms of fundraising or revenue.

Spencer Greenberg notes that most often people end up getting less done than they expect, and it is very not close.

Spencer Greenberg: The results of this poll are wild. Given that this is about daily activity, why don’t people’s anticipations adjust for how much they can get done??? I have this same problem, so I’m also wondering this about myself.

Anna Salamon: I made my predictions more pessimistic until accurate. This made my output worse (couldn’t not take predictions as targets). Eventually decoupled predictions from targets by practicing in taxing, success-unlikely games until I could fully try while ~20% likely to succeed.

Warlock: Cool! What games?

Anna Salamon: Mostly: 20 questions (modified to be harder by picking random, difficult words), and difficult rounds of the “clicker game” (a game where group picks an action while I’m out of room, then “clicks” when person comes closer to it). Also consciously practiced porting to life tasks.

In practice my observation is that ‘what one expects to accomplish’ ends up being the same as ‘what one plans on accomplishing’ or even ‘what one aims to accomplish, if things go well.’ Then the median might end up being that you accomplish what you expected, but often you will fail, whereas it will be rarer for you to accomplish substantially more than that. Indeed, if you accomplish it all, you likely stop.

My solution, I think in practice, to this is to recognize that this is what I am doing by default, and notice that I should not conflate these two things, and to be fine with often ending the day disappointed. Indeed, I frequently end the day disappointed, asking why it was not more productive. Yet still, the productivity does happen.

Cate Hall offers an excellent post that is nominally about how to cultivate agency.

It is about that. It is also more general. It is about how to accomplish things in general. How to be effective.

The central theme is what I call Finkel’s Law: Focus Only on What Matters.

Most people think agency is largely about grinding through tons of hours. It isn’t. It is about buckling down and doing the real work that determines outcomes.

Cate Hall: These days I set boundaries that would have made me ashamed at earlier points in my life: I’m offline at 6 p.m. almost every night, and rigorously observe a Sunday Sabbath where nothing with the flavor of effort is tolerated. These will seem like small things to some people, but like a mortal sin to others in the communities I run in.

My rule is never to take instructions on how hard I should work from someone who hasn’t burned out before. Very few people take this seriously enough.

I do not follow as strictly, I prefer to be more flexible with time and often not writing feels less relaxing than writing, but I am very much with Cate on setting limits.

Her other specific advice, all of which I endorse:

  1. Court Rejection. Practice making unreasonable asks. Aim high.

  2. Seek Real Feedback, especially anonymous feedback.

  3. Increase Your Surface Area For Luck. Talk to as many people as possible, see what happens, even when you’re not sure why or if the person is worthwhile.

  4. Assume Everything is Learnable. Not only skills, also many attributes. You have to be willing to do the boring work, but it can pretty much all be done.

  5. Learn to Love the Moat of Low Status, when you are acquiring new skills and you need to mess around trying but still suck at the skill.

This is all the service of Focus Only on What Matters. Look for the big edges, the things that make a big difference. That does not mean you get to neglect the fundamentals. Everyone needs to be blocking and tackling. That matters too. Then you need to also put the focus on other things that matter.

Here is her example:

Cate Hall: Two friends and I maniacally studied reads together, and we all had out-of-distribution results. But when we’d tell other pros what we were doing, the response from most was “nuh-uh, that’s not a thing.” They weren’t willing to consider the possibility that reads were valuable, maybe because they didn’t want to feel obligated to study them.

All of my agency hacks are kind of like this, in my opinion — big, glaring edges that people might rather ignore.

I think pros have largely come around since then on the value of live reads. You can still try to ignore that to avoid ‘getting leveled’ in such games, trying to rely on reads makes you exploitable, but the competitors on the amazing Game of Gold made it clear that live reads are a huge deal even among pros.

Certainly in Magic: The Gathering reads have always been huge. I would constantly fret that someone who paid enough attention could notice various things, and try to make it harder on them. I also made a lot of effort to get good at reading people in various ways, and to develop a talking game that helped me get good reads and also to get opponents to relax, while hiding information that mattered.

An even better parallel might be Fact or Fiction splits. When you play Fact or Fiction, the opponent must divide five cards into two piles, and then you choose one to keep. When the card came out, it was clearly going to get played a lot. My testing partner Seth and I realized that good divisions would be very high leverage, and we spent a lot of time going deep analyzing various splits and situations. That work directly let me steal at least one win by tricking the opponent into taking the wrong pile, getting me into the final day.

I do not do anything like enough of the things Cate is talking about here.

  1. I don’t make big asks often. When I do, I scarily often get them.

  2. I don’t sufficiently actively seek out feedback, and don’t provide a way to give it anonymously, although I do prefer to get it non-anonymously.

  3. I don’t sufficiently actively seek out meetings with others, despite high returns.

  4. I don’t devote much time to intentional skill development.

  5. I don’t like sucking at things. I do like the feeling of rapid improvement and the expectation of getting better. But I don’t appreciate it enough.

People do not appreciate true opportunity.

In the standard setup, you would retain knowledge of previous loops, your memories, experiences and skills, but everything else resets, including your physical state, no matter what.

To answer the question completely, one must ask what are the starting conditions and other rules.

If you are starting from a sufficiently terrible position with no good options, such as locked in a prison or in the middle of nowhere, you might need to spend substantial time fixing that each loop if you want to do much. It might even be impossible with perfect play.

Keeping your sanity is going to be a crucial problem if you are locked in a room or something. If you can handle that, there is a lot out there to think about, and I still think it’s a clear yes, but I do realize reasonable people could disagree. That is, however, a highly extreme case.

If you are starting from a normal position, with your usual resources, and you live in a city or even a town, you can do a hell of a lot in an hour even on the first or second loop.

Once you know the landscape, you can do quite a lot. And that’s locally. If you also have a phone or a computer? You can access all the world’s knowledge.

Consider this loop: A fully secured room, you can’t get out and no one can come in, one hour, but you have a desktop computer with internet access.

With that loop, you can watch every movie and show, read every book, study every intellectual discipline and non-physical skill, speak to a large percentage of the world’s people.

I don’t know how long I would choose to stay in that loop, but only centuries seems clearly like a massive punt. If you gave me a perfect (or good enough) memory that my knowledge and skills didn’t atrophy, I’d want a very, very long time. On the other hand, if you gave me a highly imperfect memory where I forget things, it’s very possible there is no upper bound, because I’d forget things faster than I could enjoy them, so the loop is permanently positive.

If you’re talking about loops of over a week in a normal situation, the whole thing is madness. Now you can go anywhere, do almost anything, learn almost anything to help you do it. I’d want to come out of the loop with the code for an aligned AGI.

There is also all the hedonic value. Every loop you get to eat anything you want and not face the consequences, along with every other available experience. Even if you have deep ethical qualms there are so many options, and in so many ways there is plenty of time to do the research.

Also note that if you get the last run of the loop on your way out, as is traditional, and it is not very short, then you also get almost unlimited funds, because you are the ultimate insider trader holding a full Sports Almanac, and you can do trial runs on that, and should. If you have a day out in the open and don’t leave with at least billions that’s on you.

So while Arthur initially meant to demonstrate that beyond some time frame it is a blessing, and I mostly agree with that, I think that time frame is very short.

NBER working paper claims that scientific advancement is much less a public good than we think, that the best and most useful science is done in private industry, and therefore that government funding of academic science is plausibly an active negative.

Patrick McKenzie takes his shot at explaining that the USA is on the verge of effectively forcing many companies that hire engineers to have tax rates over 100% due to forced amortization over five or even fifteen years, that many engineers are going to have to be fired if this isn’t fixed, no one wants that outcome, yet it remains unfixed.

You assume that no one wants public toilets to cost $1.7 million and not even be finished, that this must be incompetence. Do not be so confident.

Alec Stapp: “Under city law, for example, installing the Noe Valley toilet — even the free one — requires that the Recreation and Parks Department coordinate with or seek approval from San Francisco Public Works, the Planning Department, the Department of Building Inspection, the Arts Commission, the Public Utilities Commission, the Mayor’s Office on Disability, and Pacific Gas and Electric.”

Paul Graham: The people currently running San Francisco are not merely politically extreme. They’re also just plain incompetent. $1.7 million to build one public toilet isn’t a liberal vs conservative thing. Nobody wants that.

Patrick McKenzie: Do you know the Spider-Man panel with “But I don’t want to cure cancer. I want to turn people into dinosaurs.” ?

I have had some meetings with people who passionately believe in values systems that I would not have predicted would be ones someone could expouse except as a bit.

And while I wouldn’t predict someone would say “Oh toilets must cost $1.5 million that’s just science” in a meeting I would also not have predicted “Saving lives is a bad thing actually if doing so has bad distributional effects and so I will oppose it on the margin.”

Patrick is not speaking metaphorically. He is talking about vaccine distribution. Similarly, I do not think anyone actively wants to spend the extra money. However, I do think key people believe that cost is essentially irrelevant compared to being responsible and inclusive and equitable and so on, and think the status quo is righteous.

Can the government mandate a pause? Maybe not for foundation models, but for long term projects to facilitate LNG exporting that would improve the climate and our economy while helping our allies, but that sound like something they might dislike, the Biden Administration says yes.

New Jersey bans plastic bags, alternative bags people then use instead have 500% bigger carbon footprint, as the ‘reusable’ bags people use instead, in addition to being a royal pain in the ass, are a lot worse as used in practice, since the average number of uses is about two and a half.

Sar Haribhakti: “This ought to be the motto of the climate lobby: We don’t help the environment, but we feel good about it anyway.”

I worry the actual motto is ‘We actively hurt the environment, but we make people visibly suffer and hurt the economy while doing so, and that makes it all worthwhile.’

I am all for doing things that actually help the environment and actually fight climate change, provided the cost-benefit analysis is reasonable. There have been some very good programs. Increasingly, alas, the dominant mode has been otherwise.

Airfares are halved (!?) when three competitors fly a route versus a monopoly provider, and more competition drops fares further. My guess is this is overstated quite a bit due to selection effects, as the profitable routes are the ones where other airlines push to provide that competition, but I have little doubt the effect size is large. We could substantially reduce airfares while improving quality and quantity by allowing foreign airlines to compete. The arguments against doing so are Obvious Nonsense.

Government actually working, California bans ‘drip pricing,’ forces advertising of goods and services to quote final price up front. This is a clear collective action problem where it makes sense to intervene, since customers are sadly fooled by such nonsense.

Good news, I guess, San Francisco has managed to lower its $1.7 million per public toilet budget down to $725k.

Seattle implements a mandatory $5 fee on delivery apps to compensate drivers to ‘cove their living wage.’ It has now (as of the article linked) been two weeks. Sales fall by almost half, drivers are suffering.

Corie Whalen: WHO COULD HAVE PREDICTED THIS? 🥴

Seizure Salad: I’ve been following this in the Seattle subreddit. Someone ordered an $18 bowl of clam chowder and with taxes and fees (before gratuity) the total was $41.

K5: “It was three items of, you know, Thai takeout food for $122, without the delivery tip,” recalled Pettit.

She continued, “I ordered like a $12 sandwich. But then the $12 grew to $32.”

At these prices, delivery is not quite banned, but it is damn close, and instead of using such apps often I would use the apps essentially never. Of course, who is to say that was not the intention.

New York City took the opposite approach of banning outsized fees, and as a result I use delivery substantially more than under the previous regime.

IRS does not expect that many to use its direct filing option, although still enough to make it worthwhile. The system still fails to offer taxpayers the information the IRS already knows. Why shouldn’t it pre-fill the information, saving everyone time and effort and minimizing error? Seems to be more rent seeking from the tax preparers, also I suppose you could say that ‘tipping their hand’ could tell taxpayers what they could try to ‘get away with,’ someone ought to do a study, it should statistically be very easy to tell if there is an impact here. They also note that California tried pre-filled tax forms 20 years ago, but it was a failure as 80% of taxpayers did not use it. To which I say, what? That means 20% did use it. Sounds great to me.

You can have a substantial effect by calling your Congressman about a particular piece of legislation, and it only takes a few minutes. What happens with AI?

A law has been introduced in California that would impose several rules on social media platforms.

All the rules apply only to defaults. Users are free to change the settings, but as they note the defaults are powerful. Most people do not bother to change them. Here are the proposals:

  1. The default feed must be chronological, not algorithmic.

  2. The default notification settings must mute between midnight at 6am.

  3. The default settings must cap usage at one hour per day.

  4. The default settings must hide like counts.

The first two seem like clear wins. Chronological feeds are healthier. This is also a great way to target TikTok without doing something insane like the Restrict Act, making users do some work to get hit with the secret sauce.

The one hour usage cap is an odd one. I would expect the user to often remove this the first time they hit it, but perhaps many would instead take the hint as being helpful. It also would strongly help parents, as they would have a much stronger case for leaving such a restriction in place. Of course I say this as someone who has Twitter open all day every day, and is actively on it for more than an hour often.

I see what they are trying to do by hiding like counts, but I think this is a losing battle. Like and view counts are important context and provide key feedback. Yes, Scott Alexander can pull off removing them entirely, but he is the exception that proves the rule.

You do not want to push too far with such proposals. A lot of what you are counting on is that people never change their default settings.

If you push the user too far, they will essentially be forced into digging into the settings. Once they do that, they will also be far more likely to change other settings. So if you want to set good defaults, you want a set of defaults people can live with.

In general, the government mostly should not be sticking its nose in such business, especially when it is California trying to set rules for the whole world. I happen to like many of these changes, but that will often not be the case. So I would not be so sad if this particular bill passes, but in general we’d be better off leaving things alone.

California also has a new law that bans ‘drip pricing’ where the advertised price does not include all mandatory charges and fees. That one seems plainly good. The market failure being fixed here is clear. It has been such a relief that ticket sales to events use all-in pricing now.

In Soviet Oakland, when your small business is broken into, City bills You.

A crowd in San Francisco surrounded and vandalized the a fully autonomous Waymo vehicle, throwing a firework inside that lit the car on fire. Tyler Cowen says ‘In some alternate univsere, a small drone would emerge from the burning vehicle and strike them all down.’ I am happy we instead live in the opposite universe, where the vehicle lets the crowd do this, but also we have full camera footage and I very much hope that the police apprehend and punish everyone involved.

Zac Hill notes the strange economics of semi-organized theft:

Zac Hill: Things I tried and failed to get at my local @Walgreens just now due to (what I assume to be) the retail theft epidemic:

-> Deodorant

-> Toilet Paper

-> Toothpaste

Things apparently left untouched by this terrible blight/scourge:

-> A *staggeringvariety of “dual vibrating massagers”

Later, he follows up:

Zac Hill: I was talking with someone on Twitter who was insisting to me that the wild shit I personally saw at my local Walgreens didn’t happen. It now appears we’ve figured out the root cause!

Peter Hermann: A shocking twist in a series of Walgreens robberies in Chinatown: ‘An inside actor [was] helping to orchestrate the entire robbery conspiracy.’

Thief rips out all the phones on the ground floor of an Apple store one by one, then walks out casually past a police car and drives away. A response says Apple responds by bricking all the phones and even any phone that later uses their component parts, so people buy used phones that are bricked on Facebook marketplace, as if that makes this acceptable. The cost to Apple must be very large, that loss is fully a deadweight loss, and people buying the phones get scammed and have no useful phone. So arguably this makes the situation even worse.

Once again, I am left to wonder how the store is still there at all? How does our civilization not collapse, if there is zero risk of enforcement of laws against theft?

Our civilization also needs to figure out that it is not a victimless crime to steal a car.

Occupational licensing regimes greatly contribute to recidivism. At minimum, we could do more to mitigate the damage here, but much better not to throw up the barriers in the first place. A reform proposal is linked here.

Wayne Hall: There are many cases where people are released from prison without the nessassary documents to work. It can take 90 days to get these in order and to not be a burden. It seem it would be an easy win to ensure they are ready to work on release with a copy of their social security card and a state issued id.

Anna Salamon on the concept of ‘Believing In’ something or someone, considering that as something worth counting on, acting as if, investing in, championing and such, as distinct from believing a fact about the world or the probability of an outcome. I believe there is much wisdom here. Also see the concept of Steam.

Neal Stephenson to release Polostan on October 15, which sounds very Stephenson, potentially the start of an early 20th century version of the Baroque Cycle. I notice haven’t read his last few novels, despite enjoying his earlier ones a lot. I wonder if I am making a mistake.

Dan Wang’s 2023 letter. Almost odd to see thoughtful musing about the future that mentions offhand but essentially ignores both AI and fertility collapse as key elements. It is hard not to be pessimistic about China after reading. How can a country so profoundly unfree compete on AI or anything else? Its people seem, based on this, to have rejected the idea of having a future.

Dan also makes the claim that in Asia you can get spectacular food prepared for you everywhere dirt cheap, it is around each corner, whereas in America you can only get excellent food at a premium, and he feels compelled to cook. I am skeptical that things are so good elsewhere, but also the premium here is not so high. Even when it is not cheap, great food is still remarkably cheap, so long as you do not ‘go nuts.’ I do agree with Dan that New York City has gotten more expensive across the board over the last several years and service reliability is a little bit worse. I see this as the market correcting itself. An important point when living here is that you are buying location at a premium because it is worth a lot to have access to all the things, so skimping on other things to save relatively little (including on food quality) likely does not make sense.

Adaobi publishes a sneaky post called ‘How to do things if you’re not that smart and don’t have any talent,’ which is actually telling you how to accomplish things no matter who you are. As in, a lot of what determines success of a person or project has very little to do with talent or intelligence, it is grit and moving fast and hard work and doing the boring stuff and improving things when you see an opportunity and not being afraid of mild social awkwardness and asking stupid questions and cold emailing and learning unnamed skills and showing up at hard times and figuring out the first step and finishing what you start and so on.

Andrew Biggs makes the case for eliminating the tax preference for retirement accounts. This mostly benefits the rich, does not obviously increase net savings values, causes lots of hoops to be jumped through, and we can use the money to shore up social security instead, or I would add to cut income tax rates. This would be obviously great on the pure economics, assuming it did not retroactively confiscate existing savings and only applied going forward. But as Matthew Yglesias says, political nonstarter, so much so that not even I support doing it.

Sleep matters a lot.

Nate Silver: Just for me personally it feels like with math tasks there’s a ~10% performance boost from being well-rested but with verbal tasks like writing it’s maybe literally 100%.

As several commenters suggested, it is largely about deep versus shallow, focus versus autopilot, at least for me. There are certain types of thinking that require being fully on, where lack of sleep makes me largely or entirely useless. Then there are other things that can mostly run on autopilot. What I can’t do without sleep is in some (but not all!) ways very similar to what I can’t do when dealing with kids. Much of the writing process is now in the autopilot phase, especially scanning firehoses and picking out sources. Then there are effort posts, or effort sections, where you have to be on.

Often, when a policy is overwhelmingly good, one must sell it based on a quantification of a tiny portion of its benefits. That is still often good enough.

Parth Ahya: Properly accounted for, lifting the green card limit for STEM master’s and PhD graduates would reduce the federal budget deficit by $129 billion over 10 years and $634 billion over 20 years. Great work by @heidilwilliams_, Doug Elmendorf, @BudgetModel and others.

Daniel Eth: This feels like people who talk about how anti-aging tech would reduce Medicare costs. Like, yeah, probably true, but this is such small potatoes compared to the other benefits – why are we even talking about this?

In both cases this is less crazy than it sounds, because it turns a talking point against you of increased costs into a talking point in your favor. Being able to demonstrate direct profitability is very strong evidence that such a policy is a great idea. If bringing in more STEM graduates would hurt the budget, that would be a sign it was not a great idea, whereas it helping is evidence it is indeed a great idea.

Your CEO needs to be out there communicating how great the company is. Many do not do this well, or even at all. I consider this a version of the Leaders of Men issue. There are only so many good CEOs out there. You need to hire to get the important stuff right, so if this kind of communicating is not a top priority it will often suffer.

Greg Brockman (President OpenAI): better work often comes from those striving for excellence than from those who have already achieved it.

Greg undoubtedly has achieved excellence and is also continuing to strive for it. That is the common pattern. If someone has excellence, the chances are very good they are striving for more of it. That is the best of both worlds, and the same inner drives are usually causing both. If you have to choose one or the other, it depends on your task which one is more important.

Emmett Shear asks a month ago, what are the best techniques against procrastination?

Malcolm Ocean: “chill out in a chair or on a couch, with no phone or anything to read/do/etc, until you feel like getting up and doing the thing or you get clear that you’d rather do something else”

Aaron Slodov: the yc group method is unmatched tbh, frequent check ins, progress reports, press them on metrics, etc etc mega accountability.

Visakan Veerasamy: ask em questions. whatcha (not) doin? why u wanna/gotta do it? whats hard or unpleasant about it? what r u worried about? can you make tiny progress on it, what would that look like? etc etc

kaiwan: 1) Mirroring (doing our separate things separately but in a shared space like a cafe or video call) 2) Doing the first step for them or with them

Suhail: Ask them for $1000 and you’ll pay it back in 2w or keep it depending on whether they did the task.

I find the right solutions depend on the person. For me, one key is to get rid of distractions. Another is to set it up so that your procrastination is productive, if you are procrastinating about X with Y and about Y with X then that’s the dream. I also like to gate things, as in ‘I am not doing Z until I finish this.’ Also I’ve learned to hate it when I’m procrastinating, so it feels better to do the thing.

But also I still procrastinate a lot.

Universal Music Group pulls its music from TikTok, saying TikTok only accounted for 1% of total revenue. Josh Constine says TikTok has them over a barrel, they should give away their music essentially ‘for the exposure’:

Josh Constine: Sounds boring, but actually a big deal. Top record label Univeral Music is ceasing to license music to TikTok and says the app bullied it in negotiations…

…But music popularity is dictated by TikTok, whose trends were behind 13 or the top 18 songs last year.

So either all videos using Universal artist songs muted, which sucks for users and musicians, it convinces other labels to fight alongside it for a better deal, or it caves.

Honestly, each label needs TikTok more than it needs them, given it’s become the primary music discovery mechanism. And I’d argue the tickets, merch, and streaming royalties it drives more than make up for the licensing costs.

Citation needed. Yes, hit songs will end up in TikTok videos, and songs from TikTok videos will end up as hit songs. That does not provide causation.

As usual, basically everyone will always tell every creator that on the margin that participation will be good for them long term, think of the exposure and reputational benefits, so they should work for free or almost free. And technically they are right, but also of course screw that, fyou, pay me.

Universal says that the new deal they were offered was actively worse than the old one.

Variety: With respect to the issue of artist and songwriter compensation, TikTok “proposed paying our artists and songwriters at a rate that is a fraction of the rate that similarly situated major social platforms pay,” according to UMG’s letter.

Regarding the issue of artificial intelligence, TikTok “is allowing the platform to be flooded with AI-generated recordings — as well as developing tools to enable, promote and encourage AI music creation on the platform itself — and then demanding a contractual right which would allow this content to massively dilute the royalty pool for human artists, in a move that is nothing short of sponsoring artist replacement by AI,” UMG said.

In addition, according to Universal Music, TikTok “makes little effort to deal with the vast amounts of content on its platform that infringe our artists’ music and it has offered no meaningful solutions to the rising tide of content adjacency issues, let alone the tidal wave of hate speech, bigotry, bullying and harassment on the platform.”

I am not one to believe the claims of a music label or of a social network. Here my gut strongly tells me Universal is mostly telling the truth, that TikTok is indeed doing all these things, and that they are right to pull the content.

I agree with Daniel Eth here, the news is not that Americans are inconsistent about which tactics are acceptable and favor the causes they find just, it is that Americans mostly do not do this, and are remarkably consistent and honorable here.

YouGov America: Americans’ views of protest tactics such as picketing or blocking traffic aren’t fixed: Acceptance of tactics depends on support of the cause that protesters are advocating

I would love to see a breakdown of how much of this is a gradual shift in everyone’s views, versus a few people who radically shift their views. For handing out fliers, for example, consider two possible worlds:

  1. Most people have a mostly consistent view, but 12% are fundamentally against free speech, so they think that a flier saying ‘apple pie is good’ is always acceptable because apple pie is good, and one saying ‘apple pie is bad’ is never acceptable because apple pie is good.

  2. Many people are slightly less approving of the other perspective.

As usual this is doubtless a mix, my guess is a more of #1 is going on, there is a fixed pool of ~10% of people who essentially think the other side is always wrong.

We also get some issue opinions, free speech nominally remains super popular.

The obvious question is, if you do not actively oppose free speech, then how can you say that your opponents handing out fliers is never acceptable? Yet that second group is substantially bigger.

I would also add that these responses show highly good sense overall.

We have, essentially, two categories of things.

In the first we have handing out flyers, marching long distances, boycotting products and picketing. These are all at core clear forms of free expression, rather than attempts to inflict damage and make the lives of others worse, so long as one is not using violence to stop someone who attempts to cross a picket line.

Americans find all these broadly acceptable, with at most 28% opposition (with 65%+ actively in favor) even for opponents. I agree, all of these are always acceptable.

Then there is the second group: Disrupting public events, defacing property, blocking traffic and rioting. These are all centrally about causing harm and inflicting damage. Give us what we want, or else we will make your lives worse. Disrupting events is the least unacceptable because it at least plausibly targets the particular thing you are objecting to. Defacing property and blocking traffic are lashing out at random, forms of collective punishment, and rioting is that but violent.

Americans find all these broadly unacceptable, with at most 25% approving even for favored causes, and at least 66% opposed, and the latter three correctly considered substantially worse than that.

So this is the exact right order from most acceptable to least acceptable, and the majority broadly is right in each case.

I am curious about the 4% of people are who think that rioting is always acceptable, and how they think that works. Presumably they simply want to watch the world burn.

If you are considering protesting, this provides clear guidance. You should go ahead and hand out fliers, go on marches, boycott and picket. Have your rallies, do active expression.

You should not, however, disrupt events, deface property, block traffic or riot. This mainly serves to piss people off. If I learn that you are blocking traffic in order to demand the government change its actions, or even worse that overseas governments or corporations magically change their actions, then you are not going to win hearts and minds.

Emmett Shear reads Christopher Alexander’s A Pattern Language, notes the vast overconfidence throughout and that many claims seem false, wonders what all the fuss is about. Turns out the answer is that he correctly noticed the early macro assertions on urban design and land use were Obvious Nonsense. I noticed that too, but thing improve, and Shear notices he got trapped in a cynical perspective. What confuses me is that he still made it through the full thousand pages. One day, architecture sequence of posts. One day.

We made it weird at the planet reunion (1 min video).

Too many working papers.

Good question.

Sarah Constantin: I do notice a lot of people whose story is “I got sick of the shallow hedonists who just wanna hang out” and I’m always like “hey…I would LOVE to hang out…where are these people? can I meet them?”

The problem is that when we ‘just want to hang out’ we want to do that with people who aren’t so shallow that all they want to do is hang out. That gets boring. Then we end up not having people with which to just hang out. Whoops.

Anton: to a medieval peasant this would be exactly backwards makes you think

The Golden Sir (2019): Me sowing: Haha fuck yeah!!! Yes!!

Me reaping: Well this fucking sucks. What the fuck.

Yep. That’s right.

Insanity. Pure insanity.

Vivek Ramaswamy: On Day 1, *instantlyfire 50% of federal bureaucrats. Here’s how: if your SSN ends in an odd number, you’re fired. That downsizes government by half. Absolutely *nothingwill break as a result. It doesn’t violate civil service rules because mass layoffs are exempt. SHUT IT DOWN.

Matt Darling: Vivek, don’t announce the randomization assignment a year before treatment!

McSweeney’s nails it: Son, you will not binge-watch LOST – you’ll watch one episode a week and be frustrated like mom and I did.

In addition to being funny this take is correct. Binging anything actively good or interesting is a mistake. Sure, if you want to binge a cooking show or procedural go right ahead. Law & Order marathons exist for a reason. But with shows that are actively good you want to pace yourself. You get diminishing marginal returns, and then the show is gone.

Once a week is still a little extreme, even for me. And we get to test this out even today, with shows like Loki, where a full week is long enough I forget details.

I would suggest the following rules, keep in mind these are upper limits not requirements:

Unlimited Binge: Procedurals, sports.

Two episodes per day: Pulpy stuff, semi-procedural genre shows, 4+ seasons minimum.

Measles erupts in Florida school where 11% of kids are unvaccinated

outbreak potential —

Over 100 children at the school are susceptible to virus.

Florida health officials on Sunday announced an investigation into a cluster of measles cases at an elementary school in the Fort Lauderdale area with a low vaccination rate, a scenario health experts fear will become more and more common amid slipping vaccination rates nationwide.

On Friday, Broward County Public School reported a confirmed case of measles in a student at Manatee Bay Elementary School in the city of Weston. A local CBS affiliate reported that the case was in a third-grade student who had not recently traveled. On Saturday, the school system announced that three additional cases at the same school had been reported, bringing the current reported total to four cases.

On Sunday, the Florida Department of Health in Broward County (DOH-Broward) released a health advisory about the cases and announced it was opening an investigation to track contacts at risk of infection.

At Manatee Bay Elementary School, the number of children at risk could be over 100 students. According to a Broward County vaccine study reported by the local CBS outlet, only 89.31 percent of students at Manatee Bay Elementary School were fully immunized in the 2023/2024 school year, which is significantly lower than the target vaccination coverage of 95 percent. The school currently has 1,067 students enrolled, suggesting that up to 114 students are vulnerable to the infection based on their vaccination status.

Measles is one of the most contagious viruses known. It spreads via respiratory and airborne transmission. The virus can linger in air space for up to two hours after an infected person has been in an area. People who are not vaccinated or have compromised immune systems are susceptible, and up to 90 percent of susceptible people exposed to the virus will become infected. Measles symptoms typically begin around eight to 14 days after exposure, but the disease can incubate for up to 21 days. The symptoms begin as a high fever, runny nose, red and watery eyes, and a cough before the telltale rash develops. Infected people can be contagious from four days before the rash develops through four days after the rash appears, according to the Centers for Disease Control and Prevention. About 1 in 5 unvaccinated people with measles is hospitalized, the CDC adds, while 1 in 20 infected children develop pneumonia and up to 3 in 1,000 children die of the infection.

Those who are not immunocompromised and are fully vaccinated against measles (who have received two doses of the Measles, Mumps, and Rubella (MMR) vaccine) are generally not considered at risk. The two doses are about 97 percent effective at preventing measles and protection is considered to be life-long.

The DOH-Broward said it is now “identifying susceptible contacts that may be candidates for post-exposure prophylaxis through MMR or immunoglobulin.”

While the risk of measles is generally low in the US—the country declared it eliminated in 2000—the threat of large outbreaks is growing as vaccination rates slip. Many cases in the US are linked to travel from countries where the virus still circulates. But, if a travel-related case lands in a pocket with low vaccination coverage, the virus can take off. Such was the case in 2019, when the country tallied 1,274 measles cases and nearly lost its elimination status.

Health officials typically consider vaccination coverage of 95 percent or greater to protect from ongoing transmission. In the years since the COVID-19 pandemic began, vaccination rates among US kindergartners have slipped to 93 percent, and vaccination exemptions reached an all-time high in the latest data from the 2022-2023 school year. There are now at least 10 states that have vaccination exemption rates above 5 percent, meaning that even if every non-exempt child is vaccinated, those states will not have enough coverage to reach the 95 percent target.

The CDC has tallied 20 measles cases in the US so far this year. But that is the tally as of February 15; it does not include any of the Florida cases reported since Friday. In 2023, there were 58 measles cases reported to the CDC.

This story was updated to include additional information about measles infection outcomes.

New compact facial-recognition system passes test on Michelangelo’s David

A face for the ages —

Flatter, simpler prototype system uses 5-10 times less power than smartphone tech.

A new lens-free and compact system for facial recognition scans a bust of Michelangelo’s David and reconstructs the image using less power than existing 3D surface imaging systems.

W-C Hsu et al., Nano Letters, 2024

Facial recognition is a common feature for unlocking smartphones and gaming systems, among other uses. But the technology currently relies upon bulky projectors and lenses, hindering its broader application. Scientists have now developed a new facial recognition system that employs flatter, simpler optics that also requires less energy, according to a recent paper published in the journal Nano Letters. The team tested their prototype system with a 3D replica of Michelangelo’s famous David sculpture, and found it recognized the face as well as existing smartphone facial recognition.

The current commercial 3D imaging systems in smartphones (like Apple’s iPhone) extract depth information via structured light. A dot projector uses a laser to project a pseudorandom beam pattern onto the face of the person looking at a locked screen. It does so thanks to several other built-in components: a collimator, light guide, and special lenses (known as diffractive optical elements, or DOEs) that break the laser beam apart into an array of some 32,000 infrared dots. The camera can then interpret that projected beam pattern to confirm the person’s identity.

Packing in all those optical components like lasers makes commercial dot projectors rather bulky, so it can be harder to integrate for some applications such as robotics and augmented reality, as well as the next generation of facial recognition technology. They also consume significant power. So Wen-Chen Hsu, of National Yang Ming Chiao Tung University and the Hon Hai Research Institute in Taiwan, and colleagues turned to ultrathin optical components known as metasurfaces for a potential solution. These metasurfaces can replace bulkier components for modulating light and have proven popular for depth sensors, endoscopes, tomography. and augmented reality systems, among other emerging applications.

Hsu et al. built their own depth-sensing facial recognition system incorporating a metasurface hologram in place of the diffractive optical element. They replaced the standard vertical-cavity surface-emitting laser (VCSEL) with a photonic crystal surface-emitting laser (PCSEL). (The structure of photonic crystals is the mechanism behind the bright iridescent colors in butterfly wings or beetle shells.) The PCSEL can generate its own highly collimated light beam, so there was no need for the bulky light guide or collimation lenses needed in VCSEL-based dot projector systems.

The team tested their new system on a replica bust of David, and it worked as well as existing smartphone facial recognition, based on comparing the infrared dot patterns to online photos of the statue. They found that their system generated nearly one and a half times more infrared dots (some 45,700) than the standard commercial technology from a device that is 233 times smaller in terms of surface area than the standard dot projector. “It is a compact and cost-effective system, that can be integrated into a single chip using the flip-chip process of PCSEL,” the authors wrote. Additionally, “The metasurface enables the generation of customizable and versatile light patterns, expanding the system’s applicability.” It’s more energy-efficient to boot.

Reddit sells training data to unnamed AI company ahead of IPO

Everything has a price —

If you’ve posted on Reddit, you’re likely feeding the future of AI.

In this photo illustration the American social news

On Friday, Bloomberg reported that Reddit has signed a contract allowing an unnamed AI company to train its models on the site’s content, according to people familiar with the matter. The move comes as the social media platform nears the introduction of its initial public offering (IPO), which could happen as soon as next month.

Reddit initially revealed the deal, which is reported to be worth $60 million a year, earlier in 2024 to potential investors of an anticipated IPO, Bloomberg said. The Bloomberg source speculates that the contract could serve as a model for future agreements with other AI companies.

After an era where AI companies utilized AI training data without expressly seeking any rightsholder permission, some tech firms have more recently begun entering deals where some content used for training AI models similar to GPT-4 (which runs the paid version of ChatGPT) comes under license. In December, for example, OpenAI signed an agreement with German publisher Axel Springer (publisher of Politico and Business Insider) for access to its articles. Previously, OpenAI has struck deals with other organizations, including the Associated Press. Reportedly, OpenAI is also in licensing talks with CNN, Fox, and Time, among others.

In April 2023, Reddit founder and CEO Steve Huffman told The New York Times that it planned to charge AI companies for access to its almost two decades’ worth of human-generated content.

If the reported $60 million/year deal goes through, it’s quite possible that if you’ve ever posted on Reddit, some of that material may be used to train the next generation of AI models that create text, still pictures, and video. Even without the deal, experts have discovered in the past that Reddit has been a key source of training data for large language models and AI image generators.

While we don’t know if OpenAI is the company that signed the deal with Reddit, Bloomberg speculates that Reddit’s ability to tap into AI hype for additional revenue may boost the value of its IPO, which might be worth $5 billion. Despite drama last year, Bloomberg states that Reddit pulled in more than $800 million in revenue in 2023, growing about 20 percent over its 2022 numbers.

Advance Publications, which owns Ars Technica parent Condé Nast, is the largest shareholder of Reddit.

“so-violated”:-wyze-cameras-leak-footage-to-strangers-for-2nd-time-in-5-months

“So violated”: Wyze cameras leak footage to strangers for 2nd time in 5 months

Wyze cameras experienced a glitch on Friday that gave 13,000 customers access to images and, in some cases, video, from Wyze cameras that didn’t belong to them. The company claims 99.75 percent of accounts weren’t affected, but for some, that revelation doesn’t eradicate feelings of “disgust” and concern.

Wyze claims that an outage on Friday left customers unable to view camera footage for hours. Wyze has blamed the outage on a problem with an undisclosed Amazon Web Services (AWS) partner but hasn’t provided details.

Monday morning, Wyze sent emails to customers, including those Wyze says weren’t affected, informing them that the outage led to 13,000 people being able to access data from strangers’ cameras, as reported by The Verge.

Per Wyze’s email:

We can now confirm that as cameras were coming back online, about 13,000 Wyze users received thumbnails from cameras that were not their own and 1,504 users tapped on them. Most taps enlarged the thumbnail, but in some cases an Event Video was able to be viewed. …

According to Wyze, while it was trying to bring cameras back online from Friday’s outage, users reported seeing thumbnails and Event Videos that weren’t from their own cameras. Wyze’s emails added:

The incident was caused by a third-party caching client library that was recently integrated into our system. This client library received unprecedented load conditions caused by devices coming back online all at once. As a result of increased demand, it mixed up device ID and user ID mapping and connected some data to incorrect accounts.

In response to customers reporting that they were viewing images from strangers’ cameras, Wyze said it blocked customers from using the Events tab, then made an additional verification layer required to access the Wyze app’s Event Video section. Wyze co-founder and CMO David Crosby also said Wyze logged out people who had used the Wyze app on Friday in order to reset tokens.

Wyze’s emails also said the company modified its system “to bypass caching for checks on user-device relationships until [it identifies] new client libraries that are thoroughly stress tested for extreme events” like the one that occurred on Friday.

International Nest Aware subscriptions jump in price, as much as 100%

pricing pain —

Modern plans get a 25 percent increase, while older plans double in price.

Google’s “Nest Aware” camera subscription is going through another round of price increases. This time it’s for international users. There’s no big announcement or anything, just a smattering of email screenshots from various countries on the Nest subreddit. 9to5Google was nice enough to hunt down a pile of the announcements.

Nest Aware is a monthly subscription fee for Google’s Nest cameras. Nest cameras exclusively store all their video in the cloud, and without the subscription, you aren’t allowed to record video 24/7. There are two sets of subscriptions to keep track of: the current generation subscription for modern cameras and the “first generation Nest Aware” subscription for older cameras. To give you an idea of what we’re dealing with, in the US, the current free tier only gets you three hours of “event” video—meaning video triggered by motion detection. Even the basic $8-a-month subscription doesn’t get you 24/7 recording—that’s still only 30 days of event video. The “Nest Aware Plus” subscription, at $15 a month in the US, gets you 10 days of 24/7 video recording.

The “first-generation” Nest Aware subscription, which is tied to earlier cameras and isn’t available for new customers anymore, is doubling in price in Canada. The basic tier of five days of 24/7 video is going from a yearly fee of CA$50 to CA$110 (the first-generation sub has 24/7 video on every tier). Ten days of video is jumping from CA$80 to CA$160, and 30 days is going from CA$110 to CA$220. These are the prices for a single camera; the first-generation subscription will have additional charges for additional cameras. The current Nest Aware subscription for modern cameras is getting jumps that look similar to the US, with Nest Aware Plus, the mid-tier, going from CA$16 to CA $20 per month, and presumably similar raises across the board.

Japan is seeing jumps, too, with annual Nest Aware for modern cameras going from 6,300 yen to 8,000 yen. Again, there’s no full list of price increases anywhere for every country; at the moment, we’re working from email screenshots, but it sounds like Google is rolling out similar price increases everywhere. The bill increases are happening in about a month, on March 25, 2024. The US already saw a 25–33 percent price increase in September, and it looks like, for the modern Nest Aware plan, the prices internationally are being brought in line with those increases. Users don’t seem too happy about the price increases, naturally.

Google’s austerity era, which CEO Sundar Pichai kicked off in the second half of 2022, has come with a wave of price increases across almost every Google subscription. YouTube Premium, YouTube Music, YouTube TV, Google Workspace, and Google Cloud storage all saw price increases. The one subscription that hasn’t seen a price jump is Google One, the consumer storage plan. Not that we’re trying to give Google any more ideas.

New app always points to the supermassive black hole at the center of our galaxy

the final frontier —

iPhone compass app made with AI assistance locates the heart of the Milky Way.

On Thursday, designer Matt Webb unveiled a new iPhone app called Galactic Compass, which always points to the center of the Milky Way galaxy—no matter where Earth is positioned on our journey through the stars. The app is free and available now on the App Store.

While using Galactic Compass, you set your iPhone on a level surface, and a big green arrow on the screen points the way to the Galactic Center, which is the rotational core of the spiral galaxy all of us live in. In that center is a supermassive black hole known as Sagittarius A*, a celestial body from which no matter or light can escape. (So, in a way, the app is telling us what we should avoid.)

But truthfully, the location of the galactic core at any given time isn’t exactly useful, practical knowledge—at least for people who aren’t James Tiberius Kirk in Star Trek V. But it may inspire a sense of awe about our place in the cosmos.

“It is astoundingly grounding to always have a feeling of the direction of the center of the galaxy,” Webb told Ars Technica. “Your perspective flips. To begin with, it feels arbitrary. The middle of the Milky Way seems to fly all over the sky, as the Earth turns and moves in its orbit.”

Webb’s journey to creating Galactic Compass began a decade ago as an offshoot of his love for casual astronomy. “About 10 years ago, I taught myself how to point to the center of the galaxy,” Webb said. “I lived in an apartment where I had a great view of the stars, so I was using augmented reality apps to identify them, and I gradually learned my way around the sky.”

While Webb initially used an astronomy app to help locate the Galactic Center, he eventually taught himself how to always find it. He described visualizing himself on the surface of the Earth as it spins and tilts, understanding the ecliptic as a line across the sky and recognizing the center of the galaxy as an invisible point moving predictably through the constellation Sagittarius, which lies on the ecliptic line. By visualizing Earth’s orbit over the year and determining his orientation in space, he was able to point in the right direction, refining his ability through daily practice and comparison with an augmented reality app.

With a little help from AI

Our galaxy, the Milky Way, is thought to look similar to Andromeda (seen here) if you could see it from a distance. But since we're inside the galaxy, all we can see is the edge of the galactic plane.

In 2021, Webb imagined turning his ability into an app that would help take everyone on the same journey, showing a compass that points toward the galactic center instead of Earth’s magnetic north. “But I can’t write apps,” he said. “I’m a decent enough engineer, and an amateur designer, but I’ve never figured out native apps.”

That’s where ChatGPT comes in, transforming Webb’s vision into reality. With the AI assistant as his coding partner, Webb progressed step by step, crafting a simple app interface and integrating complex calculations for locating the galactic center (which involves calculating the user’s azimuth and altitude).

Still, coding with ChatGPT has its limitations. “ChatGPT is super smart, but it’s not embodied like a human, so it falls down on doing the 3D calculations,” he says. “I had to learn a lot about quaternions, which are a technique for combining 3D rotations, and even then, it’s not perfect. The app needs to be held flat to work simply because my math breaks down when the phone is upright! I’ll fix this in future versions,” Webb said.

Webb is no stranger to ChatGPT-powered creations that are more fun than practical. Last month, he launched a Kickstarter for an AI-rhyming poetry clock called the Poem/1. With his design studio, Acts Not Facts, Webb says he uses “whimsy and play to discover the possibilities in new technology.”

Whimsical or not, Webb insists that Galactic Compass can help us ponder our place in the vast universe, and he’s proud that it recently peaked at #87 in the Travel chart for the US App Store. In this case, though, it’s spaceship Earth that is traveling the galaxy while every living human comes along for the ride.

“Once you can follow it, you start to see the galactic center as the true fixed point, and we’re the ones whizzing and spinning. There it remains, the supermassive black hole at the center of our galaxy, Sagittarius A*, steady as a rock, eternal. We go about our days; it’s always there.”

EU accuses TikTok of failing to stop kids pretending to be adults

Getting TikTok’s priorities straight —

TikTok becomes the second platform suspected of Digital Services Act breaches.

EU accuses TikTok of failing to stop kids pretending to be adults

The European Commission (EC) is concerned that TikTok isn’t doing enough to protect kids, alleging that the short-video app may be sending kids down rabbit holes of harmful content while making it easy for kids to pretend to be adults and avoid the protective content filters that do exist.

The allegations came Monday when the EC announced a formal investigation into how TikTok may be breaching the Digital Services Act (DSA) “in areas linked to the protection of minors, advertising transparency, data access for researchers, as well as the risk management of addictive design and harmful content.”

“We must spare no effort to protect our children,” Thierry Breton, European Commissioner for Internal Market, said in the press release, reiterating that the “protection of minors is a top enforcement priority for the DSA.”

This makes TikTok the second platform investigated for possible DSA breaches after X (aka Twitter) came under fire last December. Both are being scrutinized after submitting transparency reports in September that the EC said failed to satisfy the DSA’s strict standards on predictable things like not providing enough advertising transparency or data access for researchers.

But while X is additionally being investigated over alleged dark patterns and disinformation—following accusations last October that X wasn’t stopping the spread of Israel/Hamas disinformation—it’s TikTok’s young user base that appears to be the focus of the EC’s probe into its platform.

“As a platform that reaches millions of children and teenagers, TikTok must fully comply with the DSA and has a particular role to play in the protection of minors online,” Breton said. “We are launching this formal infringement proceeding today to ensure that proportionate action is taken to protect the physical and emotional well-being of young Europeans.”

Likely over the coming months, the EC will request more information from TikTok, picking apart its DSA transparency report. The probe could require interviews with TikTok staff or inspections of TikTok’s offices.

Upon concluding its investigation, the EC could require TikTok to take interim measures to fix any issues that are flagged. The Commission could also make a decision regarding non-compliance, potentially subjecting TikTok to fines of up to 6 percent of its global turnover.

An EC press officer, Thomas Regnier, told Ars that the Commission suspected that TikTok “has not diligently conducted” risk assessments to properly maintain mitigation efforts protecting “the physical and mental well-being of their users, and the rights of the child.”

In particular, its algorithm may risk “stimulating addictive behavior,” and its recommender systems “might drag its users, in particular minors and vulnerable users, into a so-called ‘rabbit hole’ of repetitive harmful content,” Regnier told Ars. Further, TikTok’s age verification system may be subpar, with the EU alleging that TikTok perhaps “failed to diligently assess the risk of 13-17-year-olds pretending to be adults when accessing TikTok,” Regnier said.

To better protect TikTok’s young users, the EU’s investigation could force TikTok to update its age-verification system and overhaul its default privacy, safety, and security settings for minors.

“In particular, the Commission suspects that the default settings of TikTok’s recommender systems do not ensure a high level of privacy, security, and safety of minors,” Regnier said. “The Commission also suspects that the default privacy settings that TikTok has for 16-17-year-olds are not the highest by default, which would not be compliant with the DSA, and that push notifications are, by default, not switched off for minors, which could negatively impact children’s safety.”

TikTok could avoid steep fines by committing to remedies recommended by the EC at the conclusion of its investigation.

Regnier told Ars that the EC does not comment on ongoing investigations, but its probe into X has spanned three months so far. Because the DSA does not provide any deadlines that may speed up these kinds of enforcement proceedings, ultimately, the duration of both investigations will depend on how much “the company concerned cooperates,” the EU’s press release said.

A TikTok spokesperson told Ars that TikTok “would continue to work with experts and the industry to keep young people on its platform safe,” confirming that the company “looked forward to explaining this work in detail to the European Commission.”

“TikTok has pioneered features and settings to protect teens and keep under-13s off the platform, issues the whole industry is grappling with,” TikTok’s spokesperson said.

All online platforms are now required to comply with the DSA, but enforcement on TikTok began near the end of July 2023. A TikTok press release last August promised that the platform would be “embracing” the DSA. But in its transparency report, submitted the next month, TikTok acknowledged that the report only covered “one month of metrics” and may not satisfy DSA standards.

“We still have more work to do,” TikTok’s report said, promising that “we are working hard to address these points ahead of our next DSA transparency report.”
