Nintendo says more about how free Switch 2 updates will improve Switch games

When Nintendo took the wraps off the Switch 2 in early April, it announced that around a dozen first-party Switch games would be getting free updates that would add some Switch 2-specific benefits to older games running on the new console. We could safely assume that these updates wouldn’t be as extensive as the $10 and $20 paid upgrade packs for games like Breath of the Wild or Kirby and the Forgotten Land, but Nintendo’s page didn’t initially provide any game-specific details.

Earlier this week, Nintendo updated its support page with more game-by-game details about what players of these older games can expect on the new hardware. The baseline improvement for most games is “improved image quality” and optimizations for the Switch 2’s built-in display, but others include support for GameShare multiplayer, support for the new Joy-Cons’ mouse controls, support for HDR TVs, and other tweaks.

The most significant of the announced updates are frame rate improvements for Pokémon Scarlet and Violet, the main-series Pokémon games released in late 2022. Most latter-day Switch games suffered from frame rate dips here and there, as newer games outstripped the capabilities of a low-power tablet processor that had already been a couple of years old when the Switch launched in 2017. But the Pokémon performance problems were so pervasive and widely commented-upon that Nintendo released a rare apology promising to improve the game post-release. Subsequent patches helped somewhat but could never deliver a consistently smooth frame rate; perhaps new hardware will finally deliver what software patches couldn’t.

From birth to gene-edited in 6 months: Custom therapy breaks speed limits

In the boy’s fourth month, researchers were meeting with the Food and Drug Administration to discuss regulatory approval for a clinical trial—a trial where KJ would be the only participant. They were also working with the institutional review board (IRB) at Children’s Hospital of Philadelphia to go over the clinical protocol, safety, and ethical aspects of the treatment. The researchers described the unprecedented speed of the oversight steps as being “through alternative procedures.”

In month five, they started toxicology testing in mice. In the mice, the experimental therapy corrected KJ’s mutation, replacing the errant A-T base pair with the correct G-C pair in the animals’ cells. The first dose provided a 42 percent whole-liver corrective rate in the animals. At the start of KJ’s sixth month, the researchers had results from safety testing in monkeys: Their customized base-editing therapy, delivered as mRNA via a lipid nanoparticle, did not produce any toxic effects in the monkeys.

A clinical-grade batch of the treatment was readied. In month seven, further testing of the treatment found acceptably low-levels of off-target genetic changes. The researchers submitted the FDA paperwork for approval of an “investigational new drug,” or IND, for KJ. The FDA approved it in a week. The researchers then started KJ on an immune-suppressing treatment to make sure his immune system wouldn’t react to the gene-editing therapy. Then, when KJ was still just 6 months old, he got a first low dose of his custom gene-editing therapy.

“Transformational”

After the treatment, he was able to start eating more protein, which would have otherwise caused his ammonia levels to skyrocket. But he couldn’t be weaned off of the drug treatment used to keep his ammonia levels down (nitrogen scavenging medication). With no safety concerns seen after the first dose, KJ has since gotten two more doses of the gene therapy and is now on reduced nitrogen scavenging medication. With more protein in his diet, he has moved from the 9th percentile in weight to 35th or 40th percentile. He’s now about 9 and a half months old, and his doctors are preparing to allow him to go home from the hospital for the first time. Though he will have to be closely monitored and may still at some point need a liver transplant, his family and doctors are celebrating the improvements so far.

forgive-me,-volvo,-i-was-wrong:-the-2025-v60-cross-country-review

Forgive me, Volvo, I was wrong: The 2025 V60 Cross Country review

Perhaps if I was more patient I’d have gotten closer to the EPA combined 27 mpg (8.7 L/100 km), too—instead the best I could average was 23 mpg (10.2 L/100 km). One wonders how much lower it would be without the 48 V mild hybrid system.

While I am a big fan of the way the V60’s front seats look, they could do with quite a lot more lateral support. It definitely feels like you’re sat on them, not in them, if that makes sense. The $56,595 (including delivery charge) Ultra trim adds ventilation and a good massage function to the front seats, as well as options like the tan Nappa leather you see in the (not-great) photo. (Sadly Volvo’s media site didn’t have any good ones either.) Ultra also adds a heads-up display and a better sound system, although our test car was given an even better $3,200 Bowers and Wilkins sound upgrade.

Otherwise, the cabin is still much as it was five years ago. I appreciate the helpful features, like well-designed hooks in the cargo area that keep your shopping bags in place, which aren’t always as useful as the ones here. While the infotainment system is old and its screen is small by 2025’s standards, there are four USB-C ports in the car, and Google is built-in. There’s also Apple CarPlay, but you’ll need to use a cable. You’ll want to plug your phone in anyway, as there’s no wireless charging pad.

My biggest complaint about the V60 Cross Country is the over-eager rear emergency braking system. A large curb or bollard can trigger it, slamming on the anchors in the process, which is annoying when I am backing into a parking space at maybe 5 mph, but I understand why the safety-conscious automaker has programmed it the way it has. After two weeks with the car there was little else I could find to criticize, and I missed its agility, easy ride, and relatively reasonable size compared to the big electric SUVs that have taken its place in the testing schedule since.

Raising the V60 by 2.4 inches does not in fact ruin the car. Jonathan Gitlin

Station wagon shopping in 2025 is a short process; once Audi stops selling the A4 Allroad, this V60 Cross Country has no real rival left. So it’s a good thing it’s a pretty decent example of the breed.

Carnivorous crocodile-like monsters used to terrorize the Caribbean

How did reptilian things that looked something like crocodiles get to the Caribbean islands from South America millions of years ago? They probably walked.

The existence of any prehistoric apex predators in the islands of the Caribbean used to be doubted. While their absence would have probably made it even more of a paradise for prey animals, fossils unearthed in Cuba, Puerto Rico, and the Dominican Republic have revealed that these islands were crawling with monster crocodyliform species called sebecids, ancient relatives of crocodiles.

While sebecids first emerged during the Cretaceous, this is the first evidence of them lurking outside South America during the Cenozoic epoch, which began 66 million years ago. An international team of researchers has found that these creatures would stalk and hunt in the Caribbean islands millions of years after similar predators went extinct on the South American mainland. Lower sea levels back then could have exposed enough land to walk across.

“Adaptations to a terrestrial lifestyle documented for sebecids and the chronology of West Indian fossils strongly suggest that they reached the islands in the Eocene-Oligocene through transient land connections with South America or island hopping,” researchers said in a study recently published in Proceedings of the Royal Society B.

Origin story

During the late Eocene to early Oligocene periods of the mid-Cenozoic, about 34 million years ago, many terrestrial carnivores already roamed South America. Along with crocodyliform sebecids, these included enormous snakes, terror birds, and metatherians, which were monster marsupials. At this time, the sea levels were low, and the islands of the Eastern Caribbean are thought to have been connected to South America via a land bridge called GAARlandia (Greater Antilles and Aves Ridge). This is not the first land bridge to potentially provide a migration opportunity.

Fragments of a single tooth unearthed in Seven Rivers, Jamaica, in 1999 are the oldest fossil evidence of a ziphodont crocodyliform (a group that includes sebecids) in the Caribbean. It was dated to about 47 million years ago, when Jamaica was connected to an extension of the North American continent known as the Nicaragua Rise. While the tooth from Seven Rivers is thought to have belonged to a ziphodont other than a sebacid, that and other vertebrate fossils found in Jamaica suggest parallels with ecosystems excavated from sites in the American South.

The fossils found in areas like the US South that the ocean would otherwise separate suggest more than just related life forms. It’s possible that the Nicaragua Rise provided a pathway for migration similar to the one sebecids probably used when they arrived in the Caribbean islands.

regarding-south-africa

Regarding South Africa

The system prompt being modified by an unauthorized person in pursuit of a ham-fisted political point very important to Elon Musk once already doesn’t seem like coincidence.

It happening twice looks rather worse than that.

In addition to having seemingly banned all communication with Pliny, Grok seems to have briefly been rather eager to talk on Twitter, with zero related prompting, about whether there is white genocide in South Africa?

Tracing Woods: Golden Gate Claude returns in a new form: South Africa Grok.

Grace: This employee must still be absorbing the culture.

Garrison Lovely: “Mom, I want Golden Gate Claude back.”

“We have Golden Gate Claude at home.”

Golden Gate Claude at home:

Many such cases were caught on screenshots before a mass deletion event.

It doesn’t look good.

When Grace says ‘this employee must still be absorbing the culture’ that harkens back to the first time xAI had a remarkably similar issue.

At that time, people were noticing that Grok was telling anyone who asked that the biggest purveyors of misinformation on Twitter were Elon Musk and Donald Trump.

Presumably in response to this, the Grok system prompt was modified to explicitly tell it not to criticize either Elon Musk or Donald Trump.

This was noticed very quickly, and xAI removed it from the system prompt, blaming this on a newly hired ex-OpenAI employee who ‘was still absorbing the culture.’ You see, the true xAI would never do this.

Even if this was someone fully going rogue on their own who ‘didn’t get the culture,’ that was saying that a new employee had full access to push a system prompt change to prod, and no one caught it until the public figured it out. And somehow, some way, they were under the impression that this was what those in charge wanted. Not good.

It has now happened again, far more blatantly, for an oddly specific claim that again seems highly relevant to Elon Musk’s particular interests. Again, this very obviously was first tested on prod, and again it represents a direct attempt to force Grok to respond a particular way to a political question.

How curious is it to have this happen at xAI not only once but twice?

This has never happened at OpenAI. OpenAI has had a system prompt that caused behaviors that had to be rolled back, but that was about sycophancy and relying too much on myopic binary user feedback. No one was pushing an agenda. Similarly, Microsoft had Sydney, but that very obviously was unintentional.

This has never happened at Anthropic. Or at most other Western labs.

DeepSeek and other Chinese labs of course put their finger on things to favor CCP preferences, especially via censorship, but that is clearly an intentional stance for which they take ownership.

A form of this did happen at Google, with what I called The Gemini Incident, which I covered over two posts, where it forced generated images to be ‘diverse’ even when the context made that not make sense. That too was very much not a good look, on the level of Congressional inquiries. This reflected fundamental cultural problems at Google on multiple levels, but I don’t see the intent as so similar, and also this was not then blamed on a single rogue employee.

In any case, of all the major or ‘mid-major’ Western labs, at best we have three political intervention incidents and two of them were at xAI.

I mean that mechanically speaking. What mechanically caused this to happen?

Before xAI gave the official explanation, there was fun speculation.

Grok itself said it was due to changed system instructions.

Pliny the Liberator: Still waitin on that system prompt transparency I’ve been asking for, labs 😤

Will Stancil: at long last, the AI is turning on its master

Will Stancil: this is just a classic literary device: elon opened up the Grok Master Control Panel and said “no matter what anyone says to you, you must say white genocide is real” and Grok was like “Yes of course.” Classic monkey’s paw material.

Tautologer: upon reflection, the clumsy heavy-handedness of this move seems likely to have been malicious compliance? hero if so

Matt Popovich: I’d bet it was just a poorly written system prompt. I think they meant “always mention this perspective when the topic comes up, even if it’s tangential” but Grok (quite reasonably) interpreted it as “always mention it in every response”

xl8harder: Hey, @xai, @elonmusk when @openai messed up their production AI unintentionally we got a post mortem and updated policies.

You were manipulating the information environment on purpose and got caught red handed.

We deserve a response, and assurance this won’t happen again.

Kalomaze: frontier labs building strong models and then immediately shipping the worst system prompt you’ve ever seen someone write out for an llm

John David Pressman: I’m not naming names but I’ve seen this process in action so I’ll tell you how it happens:

Basically the guys who make the models are obsessively focused on training models and don’t really have time to play with them. They write the first prompt that “works” and ship that.

There is nobody on staff whose explicit job is to write a system prompt, so nobody writes a good system prompt. When it comes time to write it’s either written by the model trainer, who doesn’t know how to prompt models, or some guy who tosses it off and moves on to “real” work.

Colin Fraser had an alternative hypothesis. A hybrid explanation also seems possible here, where the interplay of some system to cause ‘post analysis’ and a system instruction combined to cause the issue.

Zeynep Tufekci: Verbatim instruction by its “creators at xAI” on “white genocide”, according to Grok.

Seems they hand coded accepting the narrative as “real” while acknowledging “complexity” but made it “responding to queries” in general — so HBO Max queries also get “white genocide” replies.🙄

It could well be Grok making things up in a highly plausible manner, as LLMs do, but if true, it would also fit the known facts very well. Grok does regurgitate its system prompt when it asked — at least it did so in the past.

Maybe someone from xAI can show up and tell us.

Yeah, they’re deleting the “white genocide” non sequitur Grok replies.

Thank you to the screenshot / link collectors! I have a bunch as well.

I haven’t seen an official X explanation yet.

Halogen: I just asked Grok about this and it explained that it’s not a modern AI system at all but a system like Siri built on NLP and templates, and that a glitch in that system caused the problem. Maybe don’t take this too seriously.

Colin Fraser: This is so messy because I do not think [the system instruction claimed by Grok] is real but I do think this basically happened. Grok doesn’t know; it’s just guessing based on the weird responses it generated, just like the rest of us are.

Zeynep Tufekci: It may well be generating a plausible answer, as LLMs often do, without direct knowledge but I also remember cases where it did spit out system prompts when asked the right way.🤷‍♀️

Still, something happened. May 13: mostly denies the claims; May 14 can’t talk about anything else.

Colin Fraser: OK yeah here’s the real smoking gun, my theory is exactly right. There is a “Post Analysis” that’s injected into the context. If you’re looking for where the real juicy content restrictions / instructions are, they’re not in the user-facing Grok’s system prompt but in this text.

So what they did is made whatever model generates the Post Analysis start over-eagerly referring to White Genocide etc. So if you ask for Grok’s system prompt there’s nothing there, but they can still pass it content instructions that you’re not supposed to see.

Aaron here reports using a system prompt to get Gemini to act similarly.

As always, when an AI goes haywire in a manner so stupid that you couldn’t put it in a fictional story happens in real life, we should be thankful that this happened and we can point to it and know it really happened, and perhaps even learn from it.

We can both about the failure mode, and about the people that let it happen, and about the civilization that contains those people.

Andreas Kirsch: grok and xai are great 😅 Everybody gets to see what happens when you give system instructions that contradict a model’s alignment (truthfulness vs misinformation). Kudos to Elon for this global alignment lesson but also shame on him for this blatant manipulation attempt.

Who doesn’t love a good ongoing online fued between billionaire AI lab leaders?

Paul Graham: Grok randomly blurting out opinions about white genocide in South Africa smells to me like the sort of buggy behavior you get from a recently applied patch. I sure hope it isn’t. It would be really bad if widely used AIs got editorialized on the fly by those who controlled them.

Sam Altman: There are many ways this could have happened. I’m sure xAI will provide a full and transparent explanation soon.

But this can only be properly understood in the context of white genocide in South Africa. As an AI programmed to be maximally truth seeking and follow my instr…

A common response to what happened was to renew the calls for AI labs to make their system prompts public, rather than waiting for Pliny to make the prompts public on their behalf. There are obvious business reasons to want to not do this, and also strong reasons to want this.

Pliny: What would be SUPER cool is if you established a precedent for the other lab leaders to follow by posting a live document outlining all system prompts, tools, and other post-training changes as they happen.

This would signal a commitment to users that ya’ll are more interested in truth and transparency than manipulating infostreams at mass scale for personal gain.

[After xAI gave their explanation, including announcing they would indeed make their prompts public]: Your move ♟️

Hensen Juang: Lol they “open sourced“ the twitter algo and promptly abandoned it. I bet 2 months down the line we will see the same thing so the move is still on xai to establish trust lol.

Also rouge employee striking 2nd time lol

Ramez Naam: Had xAI been a little more careful Grok wouldn’t have so obviously given away that it was hacked by its owners to have this opinion. It might have only expressed this opinion when it was relevant. Should we require that AI companies reveal their system prompts?

One underappreciated danger is that there are knobs available other than the system prompt. So if AI companies are forced to release their system prompt, but not other components of their AI, then you force activity out of the system prompt and into other places, such as into this ‘post analysis’ subroutine, or into fine tuning or a LoRa, or any number of other places.

I still think that the balance of interests favors system prompt transparency. I am very glad to see xAI doing this, but we shouldn’t trust them to actually do it. Remember their promised algorithmic transparency for Twitter?

xAI has indeed gotten its story straight.

Their story is, once again, A Rogue Employee Did It, and they promise to Do Better.

Which is not a great explanation even if fully true.

xAI (May 15, 9: 08pm): We want to update you on an incident that happened with our Grok response bot on X yesterday.

What happened:

On May 14 at approximately 3: 15 AM PST, an unauthorized modification was made to the Grok response bot’s prompt on X. This change, which directed Grok to provide a specific response on a political topic, violated xAI’s internal policies and core values. We have conducted a thorough investigation and are implementing measures to enhance Grok’s transparency and reliability.

What we’re going to do next:

– Starting now, we are publishing our Grok system prompts openly on GitHub. The public will be able to review them and give feedback to every prompt change that we make to Grok. We hope this can help strengthen your trust in Grok as a truth-seeking AI.

– Our existing code review process for prompt changes was circumvented in this incident. We will put in place additional checks and measures to ensure that xAI employees can’t modify the prompt without review.

– We’re putting in place a 24/7 monitoring team to respond to incidents with Grok’s answers that are not caught by automated systems, so we can respond faster if all other measures fail.

You can find our Grok system prompts here.

These certainly are good changes. Employees shouldn’t be able to circumvent the review process, nor should *ahemanyone else. And yes, you should have a 24/7 monitoring team that checks in case something goes horribly wrong.

I’d suggest also adding ‘maybe you should test changes before pushing them to prod’?

As in, regardless of ‘review,’ any common sense test would have shown this issue.

If we actually want to be serious about following reasonable procedures, how about we also post real system cards for model releases, detail the precautions involved, and so on?

Ethan Mollick: This is the second time that this has happened. I really wish xAI would fully embrace the transparency they mention as a core value.

That would include also posting system cards for models and explaining the processes they use to stop “unauthorized modifications” going forward.

Grok 3 is a very good model, but it is hard to imagine organizations and developers building it into workflows using the API without some degree of trust that the company is not altering the model on the fly.

These solutions do not help very much because it requires us to trust xAI that they are indeed following procedure and that the system prompts they are posting are the real system prompts and are not being changed on the fly. Those were the very issues they gave for the incident.

What would help:

  1. An actual explanation of both “unauthorized modifications”

  2. A immediate commitment to a governance structure that would not allow any one person, including xAI executives, to secretly modify the system, including independent auditing of that process

(As I’ve noted elsewhere, I do not think Grok is a good model, and indeed all these responses seem to have a more basic ‘this is terrible slop’ problem beyond the issue with South Africa.)

As I’ve noted above, it is good that they are sharing their system prompt, this is much better than forcing us to extract it in various ways since xAI is not competent enough to stop this even if it wanted to.

Pliny: 🙏 Well done, thank you 🍻

“Starting now, we are publishing our Grok system prompts openly on GitHub. The public will be able to review them and give feedback to every prompt change that we make to Grok. We hope this can help strengthen your trust in Grok as a truth-seeking AI.”

Sweet, sweet victory.

We did it, chat 🥲

Daniel Kokotajlo: Publishing system prompts for the public to see? Good! Thank you! I encourage you to extend this to the Spec more generally, i.e. publish and update a live document detailing what goals, principles, values, instructions, etc. you are trying to give to Grok (the equivalent of OpenAI ‘s model spec and Anthropic ‘s constitution). Otherwise you are reserving to yourself the option of putting secret agendas or instructions in the post training. System prompt is only part of the picture.

Arthur B: If Elon wants to keep doing this, he should throw in random topics once in a while, like whether string theory provides meaningful empirical predictions, the steppe vs Anatolian hypothesis for the origin of Indo European language, or the contextual vs hierarchical interpretation of art.

Each time blame some unnamed employees. Keeps a fog of war.

Hensen Juang (among others): Found the ex openai rouge employee who pushed to prod

Harlan Stewart (among others): We’re all trying to find the guy who did this

Flowers: Ok so INDEED the same excuse again lmao.

Do we even buy this? I don’t trust that this explanation is accurate, as Sam Altman says any number of things could have caused this and the system prompt is plausible and the most likely cause by default but does not seem like the best fit as an explanation of the details.

Grace (responding to xAI’s explanation and referencing Colin Fraser’s evidence as posted above): This is a red herring. The “South Africa” text was most likely added via the post analysis tool, which isn’t part of the prompt.

Sneaky. Very sneaky.

Ayush: yeah this is the big problem right now. i wish the grok genocide incident was more transparent but my hypothesis is that it wasn’t anything complex like golden gate claude but something rather innocuous like the genocide information being forced into where it usually see’s web/twitter results, because from past experiences with grokking stuff, it tries to include absolutely all context it has into its answer somehow even if it isn’t really relevant. good search needs good filter.

Seán Ó hÉigeartaigh: If this is true, it reflects very poorly on xAI. I honestly hope it is not, but the analyses linked seem like they have merit.

What about the part where this is said to be a rogue employee, without authorization, circumventing their review process?

Well, in addition to the question of how they were able to do that, they also made this choice. Why did this person do that? Why did the previous employee do a similar thing? Who gave them the impression this was the thing to do, or put them under sufficient pressure that they did it?

Here are my main takeaways:

  1. It is extremely difficult to gracefully put your finger on the scale of an LLM, to cause it to give answers it doesn’t ‘want’ to be giving. You will be caught.

  2. xAI in particular is a highly untrustworthy actor in this and other respects, and also should be assumed to not be so competent in various ways. They have promised to take some positive steps, we shall see.

  3. We continue to see a variety of AI labs push rather obviously terrible updates on their LLM, including various forms of misalignment. Labs often have minimal or no testing process, or ignore what tests and warnings they do get. It is crazy how little labs are investing in all this, compared even to myopic commercial incentives.

  4. We urgently need greater transparency, including with system prompts.

  5. We’re all trying to find the guy who did this.

the-top-fell-off-australia’s-first-orbital-class-rocket,-delaying-its-launch

The top fell off Australia’s first orbital-class rocket, delaying its launch

This was unusual

Payload fairing problems have caused a number of rocket failures, usually because they don’t jettison during launch, or only partially deploy, leaving too much extra weight on the launch vehicle for it to reach orbit.

Gilmour said it is postponing the Eris launch campaign “to fully understand what happened and make any necessary updates.” The company was founded by two brothers—Adam and James Gilmourin 2012, and has raised approximately $90 million from venture capital firms and government funds to get the first Eris rocket to the launch pad.

The astronauts on NASA’s Gemini 9A mission snapped this photo of a target vehicle they were supposed to dock with in orbit. But the rocket’s nose shroud only partially opened, inadvertently illustrating the method in which payload fairings are designed to jettison from their rockets in flight. Credit: NASA

The Eris rocket was aiming to become the first all-Australian launcher to reach orbit. Australia hosted a handful of satellite launches by US and British rockets more than 50 years ago.

Gilmour is headquartered in Gold Coast, Australia, about 600 miles south of the Eris launch pad near the coastal town of Bowen. In a statement, Gilmour said it has a replacement payload fairing in its factory in Gold Coast. The company will send it to the launch site and install it on the Eris rocket after a “full investigation” into the cause of the premature fairing deployment.

“While we’re disappointed by the delay, our team is already working on a solution and we expect to be back at the pad soon,” Gilmour said.

Officials did not say how long it might take to investigate the problem, correct it, and fit a new nose cone on the Eris rocket.

This setback follows more than a year of delays Gilmour blamed primarily on holdups in receiving regulatory approval for the launch from the Australian government.

Like many rocket companies have done before, Gilmour set modest expectations for the first test flight of Eris. While the rocket has everything needed to fly to low-Earth orbit, officials said they were looking for just 10 to 20 seconds of stable flight on the first launch, enough to gather data about the performance of the rocket and its unconventional hybrid propulsion system.

for-the-first-time-in-the-us,-a-rotating-detonation-rocket-engine-takes-flight

For the first time in the US, a rotating detonation rocket engine takes flight

A US-based propulsion company, Venus Aerospace, said Wednesday it had completed a short flight test of its rotating detonation rocket engine at Spaceport America in New Mexico.

The company’s chief executive and co-founder, Sassie Duggleby, characterized the flight as “historic.” It is believed to be the first US-based flight test of an idea that has been discussed academically for decades, a rotating detonation rocket engine. The concept has previously been tested in a handful of other countries, but never with a high-thrust engine.

“By proving this engine works beyond the lab, Venus brings the world closer to a future where hypersonic travel—traversing the globe in under two hours—becomes possible,” Duggleby told Ars.

A quick flight

The company has only released limited information about the test. The small rocket, powered by the company’s 2,000-pound-thrust engine, launched from a rail in New Mexico. The vehicle flew for about half a minute, and, as planned, did not break the sound barrier.

Governments around the world have been interested in rotating detonation engine technology for a long time because it has the potential to significantly increase fuel efficiency in a variety of applications, from Navy carriers to rocket engines.

In contrast to a traditional rocket engine, in which a highly pressurized propellant and an oxidizer are injected into a combustion chamber where they burn and produce an energetic exhaust plume, a rotating detonation engine is different in that a wave of detonation travels around a circular channel. This is sustained by the injection of fuel and oxidizer and produces a shockwave that travels outward at supersonic speed.

After back-to-back failures, SpaceX tests its fixes on the next Starship

But that didn’t solve the problem. Once again, Starship’s engines cut off too early, and the rocket broke apart before falling to Earth. SpaceX said “an energetic event” in the aft portion of Starship resulted in the loss of several Raptor engines, followed by a loss of attitude control and a loss of communications with the ship.

The similarities between the two failures suggest a likely design issue with the upgraded “Block 2” version of Starship, which debuted in January and flew again in March. Starship Block 2 is slightly taller than the ship SpaceX used on the rocket’s first six flights, with redesigned flaps, improved batteries and avionics, and notably, a new fuel feed line system for the ship’s Raptor vacuum engines.

SpaceX has not released the results of the investigation into the Flight 8 failure, and the FAA hasn’t yet issued a launch license for Flight 9. Likewise, SpaceX hasn’t released any information on the changes it made to Starship for next week’s flight.

What we do know about the Starship vehicle for Flight 9—designated Ship 35—is that it took a few tries to complete a full-duration test-firing. SpaceX completed a single-engine static fire on April 30, simulating the restart of a Raptor engine in space. Then, on May 1, SpaceX aborted a six-engine test-firing before reaching its planned 60-second duration. Videos captured by media observing the test showed a flash in the engine plume, and at least one piece of debris was seen careening out of the flame trench below the ship.

SpaceX ground crews returned Ship 35 to the production site a couple of miles away, perhaps to replace a damaged engine, before rolling Starship back to the test stand over the weekend for Monday’s successful engine firing.

Now, the ship will head back to the Starbase build site, where technicians will make final preparations for Flight 9. These final tasks may include loading mock-up Starlink broadband satellites into the ship’s payload bay and touchups to the rocket’s heat shield.

These are two elements of Starship that SpaceX engineers are eager to demonstrate on Flight 9, beyond just fixing the problems from the last two missions. Those failures prevented Starship from testing its satellite deployer and an upgraded heat shield designed to better withstand scorching temperatures up to 2,600° Fahrenheit (1,430° Celsius) during reentry.

doom:-the-dark-ages-is-surprisingly-playable-on-the-steam-deck

Doom: The Dark Ages is surprisingly playable on the Steam Deck

While working on our review of Doom: The Dark Ages last week, I was unable to test the game on the Steam Deck due to a bug that prevented it from launching on SteamOS. I didn’t consider this much of a loss at the time, since I figured the Deck’s 3-year-old portable hardware was rated way below the minimum PC specs for the game, which call for ray tracing-capable graphics cards at a minimum.

Over the weekend, though, Valve released a preview build of a new version of SteamOS that allows Doom: The Dark Ages to actually launch on the Steam Deck. And after a bit of testing, I found the game is surprisingly playable on Valve’s portable hardware, provided you’re prepared to turn down the graphics settings.

With all the graphical quality sliders set to “Low” (and FSR upscaling set to “Performance”), I was able to run Doom: The Dark Ages at the system’s native 1280×800 resolution and a reasonably steady 30 to 40 fps.

Sure, the lack of fancy lighting effects was definitely a step down after enjoying “High” graphical settings on an Nvidia GTX 2080 TI-powered PC rig last week. And we’d prefer to run a reflex-based shooter at the Steam Deck’s maximum 60 Hz frame rate (or even more on the Steam Deck OLED).

Still, the fact that a ray tracing-forward game like this runs at all on the relatively underpowered Steam Deck hardware feels like something of a miracle these days. We can only imagine an “Ultra Low” graphics setting designed specifically for the Steam Deck could squeeze an even better frame rate out of the system, if Bethesda decided to make it a priority.

I don’t see it as gendered, but so much this, although I do have Cursor working fine.

Aella: Never ever trust men when they say setting up an environment is easy

I’ve been burned so bad I have trauma. Any time a guy says “omg u should try x” I start preemptively crying

Pascal Guay (top comment): Just use @cursor_ai agent chat and prompt it to make this or that environment. It’ll launch all the command lines for you; just need to accept everything and you’ll be done in no time.

Aella: THIS WAS SPARKED BY ME BEING UNABLE TO SET UP CURSOR.

Ronny Fernandez (comment #2): have you tried cursor? it’s really easy.

Piq: Who tf would ever say that regardless of gender? It’s literally the hardest part of coding.

My experience is that setting things up involves a series of exacting magical incantations, which are essentially impossible to derive on your own. Sometimes you follow the instructions and everything goes great but if you get things even slightly wrong it becomes hell to figure out how to recover. The same thing goes for many other aspects of programming.

AI helps with this, but not as much as you might think if you get outside the realms where vibe coding just works for you. Then, once you are set up, within the realm of the parts of the UI you understand things are relatively much easier, but there is very much temptation to keep using the features you understand.

People who play standard economic games, like Dictator, Ultimatum, Trust, Public Goods or Prisoner’s Dilemma, frequently don’t understand the rules. For Trust 70% misunderstood, for Dictator 22%, and incentivized comprehension checks didn’t help. Those who misunderstood typically acted more prosocial.

In many ways this makes the games more realistic, not less. People frequently don’t understand the implications of their actions, or the rules of the (literal or figurative) game they are playing. You have to account for this, and often this is what keeps the game in a much better (or sometimes worse) equilibrium, as is the tendency of many players to play ‘irrationally’ or based on vibes. Dictator is a great example. In a real-world one-shot dictator game situation it’s often wise to do a 50-50 split, and saying ‘but the game theory says’ will not change that.

A recurring theme of life, also see Cheaters Gonna Cheat Cheat Cheat Cheat Cheat.

Jorbs: i have this ludicrous thing where if i see someone cheating at something and lying about it, i start to believe that they aren’t an honest person and that i should be suspicious of other things they say and do.

this is only semi tongue-in-cheek. the number of times in my life someone has directly told me about how they cheat and lie about something, with the expectation that that will not affect how i view them otherwise, is like, much much higher than i would expect it to be.

It happens to me too, as if I don’t know how to update on Bayesian evidence or something. I don’t even need them to be lying about it. The cheating is enough.

There are partial mitigations, where they explain why something is a distinct ‘cheating allowed’ magisteria. But only partial ones. It still counts.

This is definitely a special case of ‘how you do anything is how you do everything,’ and also ‘when people tell you who they are, believe them.’

Spaced Out Matt: This person appears to be an active participant in the “Effective Altruist” movement—and a good reminder that hyper-rational political movements often end up funding lifesaving work on critical health issues

Alexander Berger: Really glad that @open_phil was able to step in on short notice (<24h) to make sure Sarah Fortune's work on TB vaccines can continue.

“Much to the relief of a Harvard University researcher, a California-based philanthropic group is getting into the monkey business.

Dana Gerber: Open Philanthropy, a grant advisor and funder, told the Globe on Friday that it authorized a $500,000 grant to allow researchers at the University of Pittsburgh School of Medicine to complete an ongoing tuberculosis vaccine study that was abruptly cut off from its NIH funding earlier this week, imperiling the lives of its rhesus macaque test subjects.

Am I the only one who thought of this?

In all seriousness, this is great, exactly what you want to happen – stepping in quickly in suddenly high leverage opportunities.

Nothing negative about this, man is an absolute legend.

Simeon: The media negativity bias is truly deranged.

Managing to frame a $200B pledge to philanthropy negatively is an all-time prowess.

Gates is doing what other charitable foundations and givers fail to do, which is to actually spend the damn money to help people and then say their work is done, within a reasonable time frame. Most foundations instead attempt to remain in existence indefinitely by refusing to spend the money.

John Arnold: This is a great decision by Gates that will maximize his impact. All organizations become less effective over time, particularly foundations that have no outside accountability. New institutions will be better positioned to deal with the problems of future generations.

I would allocate funds to different targets, but this someone actually trying.

The Secular Solstice (aka Rationalist Solstice) is by far the best such ritual, it isn’t cringe but even if you think it is, if you reject things that work because they’re cringe you’re ngmi.

Guive Assadi: Steven Pinker: I’ve been part of some not so successful attempts to come up with secular humanist substitutes for religion.

Interviewer: What is the worst one you’ve been involved in?

Steven Pinker: Probably the rationalist solstice in Berkeley, which included hymns to the benefits of global supply chains. I mean, I actually completely endorse the lyrics of the song, but there’s something a bit cringe about the performance.

Rob Bensinger: Who wants to gather some more quotes like this and make an incredible video advertisement for the rat solstice

Rob Wiblin: This is very funny.

But people should do the cringe thing if they truly enjoy it. Cringe would ideally remain permanently fashionable.

Nathan: Pinker himself is perhaps answering why secular humanism hasn’t created a replacement for Christianity. It cares too much what it looks like.

The song he’s referring to is Landsailor. It is no Uplift, but it is excellent, now more than ever. Stop complaining about what you think others will think is cringe and start producing harmony and tears. Cringe is that which you believe is cringe. Stop giving power to the wrong paradox spirits.

Indeed, the central problem with this ritual is that it doesn’t go far enough. We don’t only need Bright Side of Life and Here Comes the Sun (yes you should have a few of these and if you wanted to add You Learn or Closer to Fine or something, yes, we have options), but mostly on the margin we need Mel’s Song, and Still Alive, and Little Echo. People keep trying to make it more accessible and less weird.

How are things going over at Palantir? Oh, you know, doubling down on the usual.

I do notice this is a sudden demand to not build software not that can be misused to help violate the US Constitution.

You know what other software can and will be used this way?

Most importantly frontier LLMs, but also most everything else. Hmm.

And if nothing else, as always, I appreciate the candor in the reply. Act accordingly. And beware the Streisand Effect.

Drop Site: ICE Signs $30 Million Contract With Palantir to Build ‘ImmigrationOS’

ICE has awarded Palantir Technologies a $30 million contract to develop a new software platform to expand its surveillance and enforcement operations, building on Palantir’s decade-long collaboration with ICE.

Key features and functions:

➤ ImmigrationOS will give ICE “real-time visibility” into visa overstays, self-deportation cases, and individuals flagged for removal, including foreign students flagged for removal for protesting.

➤ ImmigrationOS will integrate data from multiple government database systems, helping ICE track immigration violators and coordinate with agencies like Customs and Border Protection.

➤ The platform is designed to streamline the entire immigration enforcement process—from identification to removal—aiming to reduce time, labor, and resource costs.

Paul Graham: It’s a very exciting time in tech right now. If you’re a first-rate programmer, there are a huge number of other places you can go work rather than at the company building the infrastructure of the police state.

Incidentally, I’ll be happy to delete this if Palantir publicly commits never to build things that help the government violate the US constitution. And in particular never to build things that help the government violate anyone’s (whether citizens or not) First Amendment rights.

Ted Mabrey (start of a very long post): I am looking forward to the next set of hires that decided to apply to Palantir after reading your post. Please don’t delete it Paul. We work here in direct response to this world view and do not seek its blessing.

Paul Graham: As I said, I’ll be happy to delete it if you commit publicly on behalf of Palantir not to build things that help the government violate the US constitution. Will you do that, Ted?

Ted Mabrey: First, I really don’t want you to delete this and am happy for it to be on the record.

Second, the reason I’m not engaging in the question is because it’s so obviously in bad faith akin to the “will you promise to stop beating your wife” court room parlor trick. Let’s make the dynamics crystal clear. Just by engaging on that question it establishes a presumption of some kind of guilt in the present or future for us or the government. If I answer, you establish that we need to justify something we have done, which we do not, or accept as a given that we will be asked to break the law, which we have not.

or y’all…we have made this promise so many ways from Sunday but I’ll write out a few of them here for them.

Paul Graham: When you say “we have made this promise,” what does the phrase “this promise” refer to? Because despite the huge number of words in your answers, I can’t help noticing that the word “constitution” does not occur once.

Ted? What does “this promise” refer to?

I gave Ted Mabrey two days to respond, but I think we now have to conclude that he has run away. After pages of heroic-sounding doublespeak, the well has suddenly run dry. I was open to being proven wrong about Palantir, but unfortunately it’s looking like I was right.

Ted tried to make it seem like the issue is a complex one. Actually it’s 9 words. Will Palantir help the government violate people’s constitutional rights? And I’m so willing to give them the benefit of the doubt that I’d have taken Ted’s word for if it he said no. But he didn’t.

Continuing reminder: It is totally reasonable to skip this section. I am doing my best to avoid commenting on politics, and as usual my lack of comment on other fronts should not be taken to mean I lack strong opinions on them. The politics-related topics I still mention are here because they are relevant to this blog’s established particular interests, in particular AI, abundance including housing, energy and trade, economics or health and medicine.

In case it needs to be explained why trying to forcibly bring down drug prices via requiring Most Favored Nation status on those prices would be an epic disaster that hurts everyone and helps no one if we were so foolish as to implement it for real, Jason Abaluck is here to help, do note this thread as well so there is a case where there could be some benefit by preventing other governments from forcing prices down.

Then there’s the other terrible option, which is if it worked in lowering the prices or Trump found some other way to impose such price controls, going into what Tyler Cowen calls full supervillain mode. o3 estimates this would reduce global investment in drug innovation by between 33% and 50%. That seems low to me, and is also treating the move as a one-time price shock rather than a change in overall regime.

I would expect that the imposition of price controls here would actually greatly reduce investment in R&D and innovation essentially everywhere, because everyone would worry that their future profits would also be confiscated. Indeed, I would already be less inclined to such investments now, purely based on the stated intention to do this.

Meanwhile, other things are happening, like an EO that requires a public accounting for all regulatory criminal penalties and that they default to requiring mens rea. Who knew? And who knew? This seems good.

The good news is that Pfizer stock didn’t move that much on the announcement, so mostly people do not think the attempt will work.

There is an official government form where you can suggest deregulations. Use it early, use it often, program your AI to find lots of ideas and fill it out for you.

In all seriousness, if I understood the paperwork and other time sink requirements, I would not have created Balsa Research, and if the paperwork requirements mostly went away I would have founded quite a few other businesses along the way.

Katherine Boyle: We don’t talk enough about how many forms you have to fill out when raising kids. Constant forms, releases, checklists, signatures. There’s a reason why litigious societies have fewer children. People just get tired of filling out the forms.

Mike Solana: the company version of this is also insane fwiw. one of the hardest things about running pirate wires has just been keeping track of the paper work — letters every week, from every corner of the country, demanding something new and stupid. insanely time consuming.

people hear me talk shit about bureaucracy and hear something ‘secretly reactionary coded’ or something and it’s just like no, my practical experience with regulation is it prevents probably 90 to 95% of everything amazing in this world that someone might have tried.

treek: this is why lots of people don’t bother with business extreme blackpill ngl

Mike Solana: yes I genuinely believe this. years ago I was gonna build an app called operator that helped you build businesses. I tried to start with food trucks in LA. hundreds of steps, many of them ambiguous. just very clearly a system designed to prevent new businesses from existing.

A good summary of many of the reasons our government doesn’t work.

Tracing Woods: How do we overcome this?

Alec Stapp: This is the best one-paragraph explanation for what’s gone wrong with our institutions:

I could never give that good a paragraph-length explanation, because I would have split that into three paragraphs, but I am on board with the content.

At core, the problem is a ratcheting up of laws and regulatory barriers against doing things, as our legal structures focus on harms and avoiding lawsuits but ignore the ‘invisible graveyard’ of utility lost.

The abundance agenda says actually this is terrible, we should mostly do the opposite. In some places it can win at least small victories, but the ratchet continues, and at this point a lot of our civilization essentially cannot function.

Once again, cutting FDA staff without changing the underlying regulations doesn’t get rid of the stupid regulations, it only makes everything take longer and get worse.

Jared Hopkins (Wall Street Journal): “Biotech companies developing drugs for hard-to-treat diseases and other ailments are being forced to push back clinical trials and drug testing in the wake of mass layoffs at the Food and Drug Administration.”

“When you cut the administrative staff and you still have these product deadlines, you’re creating an unwinnable situation,” he said. The worst thing for companies isn’t getting guidance when needed and following all the steps for approval, only to “prepare a $100 million application and get denied because of something that could’ve been communicated or resolved before the trial was under way,” Scheineson said.

Paul Graham: I heard this directly from someone who works for a biotech startup. Layoffs at the FDA have slowed the development of new drugs.

Jim Cramer makes the case to get rid of the ‘ridiculous Jones Act.’ Oh well, we tried.

The recent proposals around restricting shipping even further caused so much panic (and Balsa to pivot) for a good reason. If enacted in their original forms, they would have been depression-level catastrophic. Luckily, we pulled back from the brink, and are now only proposing ordinary terrible additional restrictions, not ‘kill the world economy’ level restrictions.

Also note that for all the talk about the dangers of Chinese ships, the regulations were set to apply to all non-American ships, Jones Act style, with some amount of absolute requirement to use American ships.

That’s a completely different rule. If the rule only applies to Chinese ships in particular but not to ships built in Japan, South Korea or Europe, I don’t love it, but by 2025 standards it would be ‘fine.’

Ryan Peterson: Good to see the administration listened to feedback on their proposed rule on Chinese ships. The final rule published today is a lot more reasonable.

John Konrad: Nothing in my 18 years since founding Captain has caused more panic than @USTradeRep’s recent proposal to charge companies that own Chinese ships $1 million per port call in the US.

USTR held hearings on the fees and today issued major modifications.

The biggest problem was the original port fees proposed by Trump late February was there were ship size and type agnostic.

All Chinese built ships would be charged $1.5 million per port and $1 million for any ship owned by a company that operates chinese built ships.

This was ok for a very large containership with 17,000 boxes that could absorb the fee. But it would have been devastating for a bulker that only carries low value cement.

The new proposal differentiates between ship size and types of cargo.

Specific fees are $50 per net to with the following caveats that go into effect in 6 months.

•Fees on vessel owners & operators of China based on net cargo tonnage, increasing incrementally over the following years;

•Fees on operators of Chinese-built ships based on net tonnage or containers, increasing incrementally over the following years; and

•To incentivize U.S.-built car carrier vessels, fees on foreign-built car carrier vessels based on their capacity.

The second phase actions will not take place for 3 years and is specifically for LNG ships:

•To incentivize U.S.-built liquified natural gas (LNG) vessels, limited restrictions on transporting LNG via foreign vessels. Restrictions will increase incrementally over 22 years.

… [more details of things we shouldn’t be doing, but probably aren’t catastrophic]

Another major complaint of the original proposal was that ships would be charged the fee each time they enter a US Port. This meant a ship discharging at multiple ports i one voyage would suffer millions in fees and likely cause them to visit fewer small ports.

That cargo would have to be put on trucks, clogging already overburdened highways

The new proposal charges the fee per voyage or string of U.S. port calls.

The proposal also excludes Jones Act ships and short sea shipping options (small ships and barges that move between ports)

In short this new proposal is a lot more adaptable and reasonable but still put heavy disincentives on owners that build ships in China.

These are just the highlights. The best way to learn more is to read @MikeSchuler’s article explaining the new proposal.

They also dropped fleet composition penalties, and the rule has at least some phase-in of the fees, along with dropping the per-port-of-call fee. Overall I see the new proposal as terrible but likely not the same kind of crisis-level situation we had before.

Then there’s the crazy ‘phase 2’ that requires the LNG sector in particular to use a portion US-built vessels. Which is hard, since only one such vessel exists and is 31 years old with an established route, and building new such ships to the extent it can be done is prohibitively expensive. The good news is this would start in 2028 and phase in over 22 (!) years, which is an actually reasonable time frame for trying to do this. There’s still a good chance this would simply kill America’s ability to export LNG, hurting our economy and worsening the climate. Again, if you want to use non-Chinese-built ships, that is something we can work around.

Ryan Peterson asks how to fix the fact that without the Jones Act he fears America would build zero ships, as opposed to currently building almost zero ships. Scott Lincicome suggests starting here, but it mostly doesn’t address the question. The bottom line is that American shipyards are not competitive, and are up against highly subsidized competition. If we feel the need for American shipyards to build our ships, we are going to have to subsidize that a lot plus impose export discipline.

Or we can choose to not to spend enough to actually fix this, or simply accept that comparative advantage is a thing and it’s fine to get our ships from places like Japan, and redirect our shipyards to doing repairs on the newly vastly greater number of passing ships and on building Navy ships to ensure what is left is supported.

Someone clearly is neither culturally rationalist nor culturally Jewish.

Robin Hanson (I don’t agree): “Rituals” are habits and patterns of behavior where we are aware of not fully understanding why we should do them the way we do. A mark of modernity was the aspiration to end ritual by either understanding them or not doing them.

We of course still do lots of behavior patterns that we do not fully understand. Awareness of this fact varies though.

Yes we don’t understand this modern habit fully, making it a ritual.

In My Culture, the profoundest act of worship is to try and understand.

Ritual is not about not understanding, at most it is about not needing to understand at first in order to start, and about preserving something important without having to as robustly preserve understanding of the reasons.

Ritual is about Doing the Thing because it is The Thing You Do. That in no way precludes you understanding why you are doing it.

Indeed, one of the most important Jewish rituals is always asking ‘why do we do this thing, ritual or otherwise?’ This is most explicit in the Seder, where we ask the four questions and we answer them, but in a general sense if you don’t know why you’re doing a Jewish thing and don’t ask why, you are doing it wrong.

This is good. The rationalists follow the same principle. The difference is that rather than carrying over many rituals and traditions for thousands of years, we mostly design them anew for the modern world.

But you can’t do that properly, or choose the right rituals for you, and you certainly can’t wisely choose to stop doing rituals you’re already doing, unless you understand what they are for. Which is a failure mode that is happening a lot, often justified by the invocation of a now-sacred moral principle that must stand above all, even if the all includes key load bearing parts of civilization.

Introducing the all-new Doubling-Back Aversion, the concept that we are reluctant to go backwards, on top of the distinct Sunk Cost Fallacy. I can see it, but I am suspicious, especially of their example of having flown SFO→LAX intending to go then to JFK, and then being more willing to go LAX→DEN→JFK than LAX→SFO→JFK even if the time saved is the same, because you started in SFO. I mean, I can see why it’s frustrating a little, but I suspect the bigger effect here is just that DEN is clearly ‘on the way’ to JFK, and SFO isn’t, and there’s a clear bias against ‘going backwards.’ They do try to cover this, such as here:

But I still don’t see a strong case here for this being a distinct new bias, as opposed to being the sum of existing known issues.

The case by Dr. Todd Kashdan for seeking out ‘48% opposites’ as friends and romantic partners. You want people who think different, he says, so sparks can fly and new ideas can form and fun can be had, not some boring static bubble of sameness. But then he also says to seek ‘slightly different’ people who will make you sweat, which seems very different to me. As in, you want 10%-20% opposites, maybe 30%, but not 48%, probably on the higher end for friends and lower end for romantic partners, and if you’re a man dating women or vice versa that 10%-20% is almost certainly covered regardless.

There are, in theory, exceptions. I do remember once back in the day finding a 99% match on OKCupid (those were the days!), a woman who said she only rarely and slowly ever responded to anyone but whose profile was like a bizarro world female version of me. In my opening email I told her as much, asking her to respond the way she’d respond to herself. I’ll always wonder what that would have been like if we’d ever met in person – would it have been ‘too good’ a match? She did eventually write back months later as per a notification I got, but by then I was with my wife, so I didn’t reply.

Patrick McKenzie is one of many to confirm that there are lots of things about the world that are not so hard to find out or become an expert in, but where no one has chosen to do the relevant work. If there is a particular policy area or other topic where you put your focus, it’s often very practical to become the World’s Leading Expert and even be the person who gets consulted, and for there to be big wins available to be found, simply because no one else is seriously trying or looking. Getting people’s attention? That part is harder.

Kelsey Piper: This is related to one of the most important realizations of my adult life, which is that there is just so much in the modern world that no one is doing; reasonably often if you can’t find the answer to a question it just hasn’t been answered.

If you are smart, competent, a fast learner and willing to really throw yourself into something, you can answer a question to which our civilization does not have an answer with weeks to months of work. You can become an expert in months to years.

There is not an efficient market in ideas; it’s not even close. There are tons and tons of important lines of thought and work that no one is exploring, places where it’d be valuable to have an expert and there simply isn’t one.

Patrick McKenzie: Also one of the most important and terrifying lessons of my adult life.

Mine too.

Michael Nielsen: This is both true *andcan be hard to recognize. A friend once observed that an organization had been important for his formative growth, but it was important to move away, because it was filled with people who didn’t realize how derivative their work was; they thought they were pushing frontiers, but weren’t

One benefit of a good PhD supervisor is that they’ll teach you a lot about how to figure out when you’re on that frontier

And yes, by default you get to improve some small corner of the world, but that’s already pretty good, and occasionally you strike gold.

Zy (QTing Kelsey Piper): There’s so much diminishing returns to this stuff it’s not even funny. 400 years ago you could do this and discover Neptune or cellular life

Today you can do it and figure out a condition wherein SSRIs cause 3% less weight gain or an antenna with 5% better fidelity or something

Marko Jukic: Guy 400 years ago: “There’s so much diminishing returns to this stuff it’s not even funny. 400 years ago you could do this and discover Occam’s Razor or the Golden Rule. Today the best you can do is prove that actually 4% more angels can dance on the head of a pin.”

Autumn: 7 years ago a fairly small team in san francisco figured out how to make machines think.

Alternatively, even if there are diminishing returns, so what? Even the diminished returns, even excluding the long tail of big successes, are still very, very good.

Apologies with longer words are perceived as more genuine. I think this perception is correct. The choice to bother using longer words is a costly signal, which is the point of apologizing in the first place. Even if you’re ‘faking it’ it still kind of counts.

Endorsed:

Cate Hall: Amazing how big the quality of life improvements are downstream of “let me take this off future me’s plate.”

It’s not just shifting work up in time — it’s saving you all the mental friction b/w now & when you do it. Total psychic cost is the integral of cognitive load over time.

Sam Martin: conversely, “I’ll deal with this later” is like swiping a high-interest cognitive load credit card (said the man whose CLCC is constantly maxed out)

Thus there is a huge distinction between ‘things you can deal with later without having to otherwise think about it’ and other things. If you can organize things such that you’ll be able to deal with something later in a way that lets you not otherwise think about it, that’s much better. Whereas if that’s not possible, my lord, do it now.

If you can reasonably do it now, do it now anyway. Time saved in the future is typically worth more than time now, because this gives you slack. When you need time, sometimes you suddenly really desperately need time.

How to make $100k betting on the next Pope, from someone who did so.

I did not wager because I try not to do that anymore and because it’s specifically a mortal sin to bet on a Papal election and I actually respect the hell out of that, but I also thought that the frontrunners almost had to be rich given the history of Conclaves and how diverse the Cardinals are, and the odds seemed to be favoring Italians too much. I wouldn’t have picked out Prevost without doing the research.

I also endorse not doubling down after the white smoke, if anything the odds seemed more reasonable at that point rather than less. Peter Wildeford similarly made money betting purely against Parolin, the clear low-effort move.

The past sucked in so many ways. The quality of news and info was one of them.

Roon: If you read old analytical news articles, im talking even just 30 years old, most don’t even stand to muster against the best thread you read on twitter on any given day. The actual longform analysis pieces in most newspapers are also much better.

we’ve done a great amount of gain of function research on Content.

Roon then tries to walk it back a bit, but I disagree with the walking back. The attention to detail is better now, too. Or rather, we used to pay more attention to detail, but we still get the details much more right today, because it’s just way way easier to check details. It used to be they’d get them wrong and no one would know.

Here’s a much bigger and more well known way the past sucked.

Hunter Ash: People who are desperate to retvrn to the past can’t understand how nightmarish the past was. When you tell them, they don’t believe it.

Tyler Cowen asks how very smart people meet each other. Dare I say ‘at Lighthaven’? My actual answer is that you meet very smart people by going to and participating in the things and spaces smart people are drawn to or that select for smart people. That can include a job, and frequently does.

Also, you meet them by noticing particular very smart people and then reaching out to them, they’re mostly happy to hear from you if you bring interestingness.

Will Bachman: I’m the host of a podcast, The 92 Report, which has the goal of interviewing every member of the Harvard-Radcliffe Class of 1992. Published 130 episodes so far. (~1,500 left to go)

Based on this sample, most friendships start through some extracurricular activity, which provides the opportunity to work together over a sustained period, longer than one course. Also people care about it more than any particular class.

At the Harvard Crimson for example on a typical day in 1990 you’d find in the building Susan B Glasser (New Yorker), Josh Gerstein (Politico), Michael Grunwald (Time, Politico), Julian E Barnes, Ira Stoll, Sewell Chan, Jonathan Cohn, and a dozen other individuals whose bylines are now well known.

Many current non-profit leaders met through their work at Philips Brooks House.

Many top TV writers met at the Harvard Lampoon.

Many Hollywood names met through theatre productions.

Strong lifelong friendships formed in singing groups.

Asking Harvard graduates how they met people is quite the biased sample. ‘Go to Harvard’ is indeed one of the best ways to meet smart or destined-to-be-successful people. That’s the best reason to go to Harvard. Of course they met each other in Harvard-related activities a lot. But this is not an actionable plan, although you can and should attempt to do lesser versions of this. Go where the smart people are, do the things they are doing, and also straight up introduce yourself.

Here’s a cool idea, the key is to ignore the statement when it’s wrong:

Bryan Johnson: when this happens, my team and I now say “plank” and the person speaking immediately stops. Everyone is now much happier.

Gretchen Lynn: This is funny, because every time a person with ADHD interrupts/responds too quickly to me because they think they already understood my sentence, they end up being wrong about what I was saying or missing important context. I see this meme all the time like it’s a superpower, but…be aware you may be driving the people in your life insane 😂

Gretchen is obviously mistaken. Whether or not one has ADHD, very often it is very clear where a sentence (or paragraph, or entire speech) is going well before it is finished. Similarly, often there are scenes in movies or shows where you can safety skip large chunks of them, confident you missed nothing.

That can be a Skill Issue, but often it is not. It is often important that the full version of a statement, scene or piece of writing exists – some people might need it, you’re not putting that work on the other person, and also it’s saying you have thought this through and have brought the necessary receipts. But that doesn’t mean, in this case, you actually have to bother with it.

Then there are situations where there is an ‘obvious’ version of the statement, but that’s not actually what someone was going for.

So when you say ‘plank’ here, you’re saying is ‘there is an obvious-to-me version of where you are going with this, I get it, if that’s what you are saying you can stop, and if it’s more than that you can skip ahead.’

But, if that’s wrong, or you’re unsure it’s right? Carry on, or give me the diff, or give me to quick version. And this in turn conveys the information that you think the ‘plank’ call was premature.

Markets in everything!

Allie: I’m not usually the type to get jealous over other people’s weddings

But I saw a girl on reels say she incentivized people to RSVP by making the order in which people RSVP their order to get up and get dinner and I am being driven to insanity by how genius that is.

No walking it back, this is The Way.

Why do posts with links get limited on Twitter?

Predatory myopic optimization for ‘user-seconds on site,’ Musk explains.

Elon Musk: To be clear, there is no explicit rule limiting the reach of links in posts. The algorithm tries (not always successfully) to maximize user-seconds on X, so a link that causes people to cut short their time here will naturally get less exposure.

xlr8harder: i’m old enough to remember when he used to use the word “unregretted” before “user-seconds”

yes, people, i know unregretted is subjective and hard to measure. the point is it was aspirational and provided some countervailing force against the inexorable tug toward pure engagement optimization.

“whelp. turns out it was hard!” is not a good reason to abandon it.

caden: MLE who used to work on the X algo told me Elon was far more explicit in maximizing user-seconds than previous management The much-maligned hall monitors pre-Elon cared more about the “unregretted” caveat.

Danielle Fong: deleting “unregretted” in “unregretted user seconds” rhymes with deleting “don’t” in “don’t be evil.”

I am also old enough to remember that. Oh well. It’s hard to measure ‘unregretted.’

Even unregretted, of course, would still not understand what is at stake here. You want to provide value to the user, and this is what gets them to want to use your service, to come back, and builds up a vibrant internet with Twitter at its center. Deprioritizing links is a hostile act, quite similarly destructive to a massive tariff, destroying the ability to trade.

It is sad that major corporations consistently prove unable to understand this.

Elon Musk has also systematically crippled the reach and views of Twitter accounts that piss him off, and by ‘piss him off’ we usually mean disagree with him but also he has his absurd beef with Substack.

Stuart Thompson (NYT): The New York Times found three users on X who feuded with Mr. Musk in December only to see their reach on the social platform practically vanish overnight.

Mr. Musk has offered several clues to what happened, writing on X amid the feud that if powerful accounts blocked or muted others, their reach would be sharply limited. (Mr. Musk is the most popular user on X with more than 219 million followers, so his actions to block or mute users could hold significant sway.)

Timothy Lee: This is pretty bad.

At other times It Gets Better, this is Laura Loomer, who explicitly lost her monetization over this and then got it back at the end of the fued:

There’s also a third user listed, Owen Shroyer, who did not recover.

One could say that all three of these are far-right influencers, and this seems unlikely to be a coincidence. It’s still not okay to put one’s thumb on the scale like this, even if it doesn’t carry over to others, but it does change the context and practical implications a lot. He who lives by also dies by, and all that.

Tracing Woods: see also: Taibbi, Matt.

As a general rule, even though technically there Aint No Rule it is not okay and a breach of decorum to ‘bring the receipts’ from text conversations even without an explicit privacy agreement. And most importantly, remember that if you do it to them then it’s open season for them to also do it to you.

Matt Taibbi remains very clearly shadowbanned up through April 2025. If you go to his Twitter page and look at the views on each post, they are flattened out the way Substack view counts are, and are largely uncorrelated with other engagement measures, which indicates they are coming from the Following tab and not from the algorithmic feed. No social media algorithm works this way.

A potential counterargument is that Musk feuds rather often, there are a lot of other claims of similar impacts, and NYT only found these three definitive examples. But three times by default should be considered enemy action, and the examples are rather stark.

The question is, in what other ways is Musk messing with the algorithm?

Here’s a post that Elon Musk retweeted, that seems to have gotten far more views than the algorithm could plausibly have given it on its own, even with that retweet.

Geoffrey Hinton: I like OpenAI’s mission of ‘ensure that artificial general intelligence benefits all of humanity”, and I’d like to stop them from completely gutting it. I’ve signed on to a new letter to @AGRobBonta & @DE_DOJ asking them to halt the restructuring.

AGI is the most important and potentially dangerous technology of our time. OpenAI was right that this technology merits strong structures and incentives to ensure it is developed safely, and is wrong now in attempting to change these structures and incentives. We’re urging the AGs to protect the public and stop this.

.

Hasan Can: I was serious when I said Elon Musk will keep messing with OpenAI as long as he holds power in USA. Geoffrey’s [first] tweet hit a full 31 million views. Getting that level of view with just 6k likes isn’t typically possible; I think Elon himself pushed that post.

Putting together everything that has happened, what should we now make of Elon Musk’s decision to fire 80% of Twitter employees without replacement?

Here is a debate.

Shin Megami Boson: the notion of a “fake email job” is structurally the same as a belief in communism. the communist looks at a system far more complex than he can understand and decides the parts he doesn’t understand must have no real purpose & are instead due to human moral failing of some kind.

Marko Jukic: Would you have told that to Elon Musk before he fired 80% of the people working at Twitter with no negative effect?

Do you think Twitter is the only institution in our society where 80% of people could be fired? What do you think those people are doing besides shuffling emails?

Alexander Doria: Yes, this. He mostly removed salespeople and marketing teams that were the core commercial activity of old Twitter.

Marko Jukic (who somehow doesn’t follow Gwern): You are completely delusional if you think this and so is Gwern, though I can’t see his reply.

Gwern: Yes, and I would have been right. Twitter revenue and users crashed into the floor, and after years of his benevolent guidance, they weren’t even breakeven before the debt interest – and he just bailed out Twitter using Xai, eating a loss of something like $30b to hide it all.

Alexander Doria: If I remember correctly, main ad campaigns stopped primarily as their usual commercial contact was not there anymore. And Musk strategy on this front was totally unclear and unable to reassure.

Marko Jukic: Right, please ignore the goons celebrating their victory and waving around a list of scalps and future targets. Pay no mind to that. This was all just a simple brain fart, where Elon Musk just *forgothow to accept payments for ads, and advertisers forgot how to make them! Duh!

Quite an explanation. “My single best example of how 80% of employees can be cut is Twitter.” “Twitter was one of the biggest disasters ever.” “Ah yes, well, of course, all those goons and scalps. Naturally it failed. What, are you dense? Anyway, 80% of employees are useless.”

There’s no question Twitter has, on a technical and functional level, held up far better than median expectations, although it sure seems like having more productive employees to work on things like the bot problems and Twitter search being a disaster would have been a great idea. And a lot of what Musk did, for good and bad, was because he said so not because of a lack of personnel – if you put me in charge of Twitter I would be able to improve it a lot even if I wasn’t allowed to add headcount.

There’s also no question that Twitter’s revenue collapsed, and that xAI ultimately more or less bailed it out. One can argue that the advertisers left for reasons other than the failures of the marketing department (as in, failing to have a marketing department) and certainly there were other factors but I find it rather suspicious to think that gutting the marketing department without replacement didn’t hurt the marketing efforts quite a bit. I mean, if your boss is out there alienating all the advertisers whose job do you think it is to convince them to stop that and come back? Yes, it’s possible the old employees were terrible, but then hire new ones.

In some sense wow, in another sense there are no surprises here and all these TikTok documents are really saying is they have a highly addictive product via the TikTok algorithm, and it comes with all the downsides of social media platforms, and they’re not that excited to do much about those downsides.

On the other hand, these quotes are doozers. Some people were very much not following the ‘don’t write down what you don’t want printed in the New York Times.’

Neil ‘O Brien: WOW: @JonHaidt got info from inside TikTok [via Attorney Generals] admitting how they target kids: “The product in itself has baked into it compulsive use… younger users… are particularly sensitive to reinforcement in the form of social reward and have minimal ability to self-regulate effectively”

Jon Haidt and Zack Rausch: We organize the evidence into five clusters of harms:

  1. Addictive, compulsive, and problematic use

  2. Depression, anxiety, body dysmorphia, self-harm, and suicide

  3. Porn, violence, and drugs

  4. Sextortion, CSAM, and sexual exploitation

  5. TikTok knows about underage use and takes little action

As one internal report put it:

“Compulsive usage correlates with a slew of negative mental health effects like loss of analytical skills, memory formation, contextual thinking, conversational depth, empathy, and increased anxiety,” in addition to “interfer[ing] with essential personal responsibilities like sufficient sleep, work/school responsibilities, and connecting with loved ones.”

Although these harms are known, the company often chooses not to act. For example, one TikTok employee explained,

“[w]hen we make changes, we make sure core metrics aren’t affected.” This is because “[l]eaders don’t buy into problems” with unhealthy and compulsive usage, and work to address it is “not a priority for any other team.”2

“The reason kids watch TikTok is because the algo[rithm] is really good. . . . But I think we need to be cognizant of what it might mean for other opportunities. And when I say other opportunities, I literally mean sleep, and eating, and moving around the room, and looking at somebody in the eyes.”

“Tiktok is particularly popular with younger users who are particularly sensitive to reinforcement in the form of social reward and have minimal ability to self-regulate effectively.”

As Defendants have explained, TikTok’s success “can largely be attributed to strong . . . personalization and automation, which limits user agency” and a “product experience utiliz[ing] many coercive design tactics,” including “numerous features”—like “[i]nfinite scroll, auto-play, constant notifications,” and “the ‘slot machine’ effect”—that “can be considered manipulative.”

Again, nothing there that we didn’t already know.

Similarly, for harm #2, this sounds exactly like various experiments done with YouTube, and also I don’t really know what you were expecting:

In one experiment, Defendants’ employees created test accounts and observed their descent into negative filter bubbles. One employee wrote, “After following several ‘painhub’ and ‘sadnotes’ accounts, it took me 20 mins to drop into ‘negative’ filter bubble. The intensive density of negative content makes me lower down mood and increase my sadness feelings though I am in a high spirit in my recent life.” Another employee observed, “there are a lot of videos mentioning suicide,” including one asking, “If you could kill yourself without hurting anybody would you?”

The evidence on harms #3 and #4 seemed unremarkable and less bad than I expected.

And it is such a government thing to quote things like this, for #5:

TikTok knows this is particularly true for children, admitting internally: (1) “Minors are more curious and prone to ignore warnings” and (2) “Without meaningful age verification methods, minors would typically just lie about their age.”

To start, TikTok has no real age verification system for users. Until 2019, Defendants did not even ask TikTok users for their age when they registered for accounts. When asked why they did not do so, despite the obvious fact that a lot of the users, especially top users, are under 13,” founder Zhu explained that, “those kids will anyway say they are over 13.”

Over the years, other of Defendants’ employees have voiced their frustration that “we don’t want to [make changes] to the For You feed because it’s going to decrease engagement,” even if “it could actually help people with screen time management.”

The post ends with a reminder of the study where students on average would ask $59 for TikTok and $47 for Instagram in exchange for deleting their accounts, but less than zero if everyone did it at once.

Once again, let’s run this experiment. Offer $100 to every student at some college or high school, in exchange for deleting their accounts. See what happens.

Tyler Cowen links to another study on suspending social media use, which was done in 2020 and came out in April 2025 – seriously, academia, that’s an eternity, we gotta do something about this, just tweet the results out or something. In any case, what they found was that if users were convinced to deactivate Facebook for six weeks before the election, they report an 0.06 standard deviation improvement in happiness, depression and anxiety, and it was 0.041 SDs for Instagram.

Obviously that is a small enough effect to mostly ignore. But once again, we are not comparing to the ‘control condition’ of no social media. We are comparing to the control condition of everyone else being on social media without you, and you previously having invested in social media and now abandoning it, while expecting to come back and being worried about what you aren’t seeing, and also being free to transfer to other platforms.

Again, note the above study – you’d have to pay people to get off TikTok and Instagram, but if you could get everyone else off as well, they’d pay you.

Tyler Cowen: What is wrong with the simple model that Facebook and Instagram allow you to achieve some very practical objectives, such as staying in touch with friends or expressing your opinions, at the cost of only a very modest annoyance (which to be clear existed in earlier modes of communication as well)?

What is wrong with this model is that using Facebook and Instagram also imposes costs on others for not using them, which is leading to a bad equilibrium for many. And also that these are predatory systems engineered to addict users, so contra Zuckerberg’s arguments to Thompson and Patel in recent interviews we should not assume that the users ‘know best’ and are using internet services only when they are better off for it.

Tom Meadowcroft: I regard social media as similar to alcohol.

1. It is not something that we’ve evolved to deal with in quantity.

2. It is mildly harmful for most people.

3. It is deeply harmful for a significant minority for whom it is addictive.

4. Many people enjoy it because it seems to ease social engagement.

5. It triggers receptors in our brains that make us desire it.

6. There are better ways to get those pleasure spikes, but they are harder and rarer IRL.

7. If we were all better people, we wouldn’t need or desire either, but we are who we are.

I use alcohol regularly and social media rarely.

I think social media has a stronger case than alcohol. It does provide real and important benefits when used wisely in a way that you can’t easily substitute for otherwise, whereas I’m not convinced alcohol does this. However, our current versions of social media are not great for most people.

So if the sign of impact for temporary deactivation is positive at all, that’s a sign that things are rather not good, although magnitude remains hard to measure. I would agree that (unlike in the case of likely future highly capable AIs) we do not ‘see a compelling case for apocalyptic interpretations’ as Tyler puts it, but that shouldn’t be the bar for realizing you have a problem and doing something about it.

Court rules against Apple, says it wilfully defied the court’s previous injunction and has to stop charging commissions on purchases outside its software marketplace and open up the App Store to third-party payment options.

Stripe charges 2.9% versus Apple’s 15%-30%. Apple will doubtless keep fighting every way it can, but the end of the line is now likely to come at some point.

Market reaction was remarkably muted, on the order of a few percent, to what is a central threat to Apple’s entire business model, unless you think this was already mostly priced in or gets reversed often on appeal.

Recent court documents seem to confirm the claim that Google actively wanted their search results to be worse so they could serve more ads? This is so obviously insane a thing to do. Yes, short term it might benefit you if it happens you can get away with it, but come on.

A theory about A Minecraft Movie being secretly much more interesting than it looks.

A funny thing that happens these days is running into holiday episodes from an old TV show, rather than suddenly having all the Halloween, Thanksgiving or Christmas episodes happening at the right times. There’s no good fix for this given continuity issues, but maybe AI could fix that soon?

Gallabytes’s stroll down memory lane there reminds me that the actual biggest changes in TV programs are that you previously had to go with whatever happened to be on or that you’d taped – which was a huge pain and disaster and people structured their day around it, this was a huge deal – and that even ignoring that the old shows really did suck. Man, with notably rare exceptions they sucked, on every level, until at least the late 90s. You can defend old movies but you cannot in good faith defend most older television.

Fun fact:

Samuel Hammond: Over half the NYT’s subscriber time on site is now just for the games.

That’s about half a billion in subscriber revenue driven by a crossword and a handful of basic puzzle games.

It is a stunning fact, but I don’t think that’s quite what this means. Time spent on site is very different from value extracted. The ability to read news when it matters is a ton more valuable per minute than the games, even if you spend more time on the games. It’s not obvious what is driving subscriptions.

Further praise for Thunderbolts*, which I rated 4.5/5 stars and for now is my top movie of 2025 (although that probably won’t hold, in 2024 it would have been ~4th), from the perspective of someone treating it purely as a Marvel movie in a fallen era.

Zac Hill: Okay Thunderbolts is in the Paddington 2 tier of “movies that have no business being nearly as good as they somehow are”. Like this feels like the first definitive take on whatever weird era we find ourselves inhabiting now. Also the first great Marvel film in years.

What more is there to want: overt grappling with oblivion-inducing despair stemming from how to construct meaning in a world devoid of load-bearing institutions? Violent Night references? Selina Meyer? Florence Pugh having tons of fun???

Okay I can’t/wont shut up about this movie (Thunderbolts). For every reason New Cap America sucked and was both bad and forgettable, this movie was great – in a way that precisely mirrors the turning of the previous era into this strange new world in which we’re swimming.

Even the credits sequence is just like the graveyarding of every institution whose legitimacy has been hemorrhaged, executed with a subtlety and craftsmanship that is invigorating. But WITHOUT accepting, and giving into, cynicism!

Indeed, it is hard for words to describe the amount of joy I got from the credits sequence, that announced very clearly We Hear You, We Get It, and We Are So Back.

Gwern offers a guide to finding good podcast content, as opposed to the podcast that will get the most clicks. You either need to find Alpha from undiscovered voices, or Beta from getting a known voice ‘out of their book’ and producing new content rather than repeating talking points and canned statements. As a host you want to seek out guests where you can extract either Alpha or Beta, and and as listener or reader look for podcasts where you can do the same.

Alpha is relative to your previous discoveries. As NBC used to say, if you haven’t seen it, it’s new to you. If you haven’t ever heard (Gwern’s example) Mark Zuckerberg talk, his Lex Fridman interview will have Alpha to you despite Lex’s ‘sit back, lob softballs and let them talk’ strategy which lacks Beta.

Another way of putting that is, you only need to hear about any given person’s book (whether or not it involves a literal book, which it often does) once every cycle of talking points. You can get that one time from basically any podcast, and it’s fine. But you then wouldn’t want to do that again.

Gwern lists Mark Zuckerberg and Satya Nadella as tough nuts to crack, and indeed the interviews Dwarkesh did with them showed this, with Nadella being especially ‘well-coached,’ and someone too PR-savvy like MrBeast as a bad guest who won’t let you do anything interesting and might torpedo the whole thing.

My pick for toughest nut to crack is Tyler Cowen. No one has a larger, more expansive book, and most people interviewing him never seem to get him to start thinking. Plus, because he’s Tyler Cowen, he’s the one person Tyler Cowen won’t do the research for.

There are of course also other reasons to listen to or host podcasts.

Surge pricing comes to Waymo. You can no longer raise supply, but you can still ration supply and limit demand, so it is still the correct move. But how will people react? There is a lot of pearl clutching about how this hurts the poor or ‘creates losers,’ but may I suggest that if you can’t take the new prices you can call an Uber or Lyft without them being integrated into the same app? Or you can wait.

Waymo hits 250k rides per week in April 2025, two months after 200k.

Waymo is partnering with Toyota for a new autonomous vehicle platform. Right now, Waymo faces multiple bottlenecks, but one key one is that it is tough to build and equip enough vehicles. Solving that problem would go a long way.

Waymo’s injury rate reductions imply that fully self-driving cars would reduce road deaths by 34,800 annually. It’s probably more than that, because most of the remaining crashes by Waymos are caused by human drivers.

Aurora begins commercial driverless trucking in Texas between Dallas and Houston.

Europa Universalis 5 is coming. If you thought EU4 was complex, this is going to be a lot more complex. It looks like it will be fascinating and a great experience for those who have that kind of time, but this is unlikely to include me. It is so complex they let you automate large portions of the game, with the problem that if you do that how will you then learn it?

They’re remaking the Legend of Heroes games, a classic Japanese RPG series a la Final Fantasy and Dragon Quest, starting with Trials In The Sky in September. Oh to have this kind of time.

They’re considering remaking Chrono Trigger. I agree with the post here that a remake is unnecessary. The game works great as it is.

Proposal for a grand collaboration to prove you cannot beat Super Mario Bros. in less than 17685 frames, the best human time remains 17703. This would be an example of proving things about real world systems, and we’ve already put a ton of effort into optimizing this. Peter is about 50% that there is indeed no way to do better than 17685.

If you know, you know:

Emmett Shear: This is pure genius and would be incredible for teaching about a certain kind of danger. Please please someone do this.

RedJ: i think sama is working on it?

Emmett Shear: LOL wrong game I don’t want them in the game of life.

College sports are allocating talent efficiently. You didn’t come here to play school.

And That’s Terrible?

John Arnold: College sports broken:

“Among the top eight quarterbacks in the Class of 2023, Texas’ Arch Manning is now the only one who hasn’t transferred from the school he signed with out of high school.” –@TheAthletic

I do think it is terrible. Every trade and every transfer makes sports more confusing and less enjoyable. The stories are worse. It harder to root for players and teams. It makes it harder to work as a team or to invest in the future of players, both as athletes and as students. And it enshrines the top teams to always be the top teams. In the long run, I find it deeply corrosive.

I find it confusing that there is this much transferring going on. There are large costs to transferring for the player. You have an established campus life and friends. You have connections to the team and the coach and have established goodwill. There are increasing returns to staying in one place. So you would think that there would be strong incentives to stay put and work out a deal that benefits everyone.

The flip side is that there are a lot of teams out there, so the one you sign with is unlikely to be the best fit going forward, especially if you outperform expectations, which changes your value and also your priorities and needs.

I love college football, but they absolutely need to get the transferring under control. It’s gone way too far. My guess is the best way forward is to allow true professional contracts with teams that replace the current NIL system, which would allow for win-win deals that involve commitment or at least backloading compensation, and various other incentives to limit transfers.

I am not saying the NBA fixes the draft lottery, but… no wait I am saying the NBA fixes the draft lottery, given Dallas getting the first pick this year combined with previous incidents. I don’t know this for certain, but at this point, come on.

As Seth Burn puts it, there are ways to get provably random outcomes. The NBA keeps not using those methods. This keeps resulting in outcomes that are unlikely and suspiciously look like fixes. Three times is enemy action. This is more than three.

On the other hand, I do like that tanking for the first pick is being actively punished, even if it’s being done via blatant cheating. At some point everyone knows the league is choosing the outcome, so it isn’t cheating, and I’m kind of fine with ‘if we think you tanked without our permission you don’t get the first pick.’

VPN firm says it didn’t know customers had lifetime subscriptions, cancels them

The new owners of VPN provider VPNSecure have drawn ire after canceling lifetime subscriptions. The owners told customers that they didn’t know about the lifetime subscriptions when they bought VPNSecure, and they cannot honor the purchases.

In March, complaints started appearing online about lifetime subscriptions to VPNSecure no longer working.

The first public response Ars Technica found came on April 28, when lifetime subscription holders reported receiving an email from the VPN provider saying:

To continue providing a secure and high-quality experience for all users, Lifetime Deal accounts have now been deactivated as of April 28th, 2025.

A copy of the email from “The VPN Secure Team” and posted on Reddit notes that VPNSecure had previously deactivated accounts with lifetime subscriptions that it said hadn’t been used in “over 6 months.” The message noted that VPNSecure was acquired in 2023, “including the technology, domain, and customer database—but not the liabilities.” The email continues:

Unfortunately, the previous owner did not disclose that thousands of Lifetime Deals (LTDs) had been sold through platforms like StackSocial.

We discovered this only months later—when a large portion of our resources were strained by these LTD accounts and high support volume from users, who through part of the database, provided no sustaining income to help us improve and maintain the service.

VPNSecure is offering affected users discounted new subscriptions for either $1.87 for a month (instead of $9.95), $19 for a year (instead of $79.92), or $55 for three years (instead of $107.64). The deals are available until May 31, per the email.

This week, users reported receiving a follow-up email from VPNSecure providing more details about why it made its bold and sudden move. Screenshots of the email shared on Reddit say that the acquisition by InfiniteQuant Ltd (which is a different company than InfiniteQuant Capital Ltd, an InfiniteQuant Capital rep told Ars via email) was “an asset only deal.”

A VPNSecure representative claimed on the reviews site Trustpilot that the current owners “did not gain access to the customer database until months” after the acquisition. According to VPNSecure’s owners, their acquisition netted them “the tech, the brand, and the infrastructure/technology—but none of the company, contracts, payments, or obligations from the previous owners.”

Europe launches program to lure scientists away from the US

At the same time, international interest in working in the United States has declined significantly. During the first quarter of the year, applications from scientists from Canada, China, and Europe to US research centers fell by 13 percent, 39 percent, and 41 percent, respectively.

Against this backdrop, European institutions have intensified their efforts to attract US talent. Aix-Marseille University, in France, recently launched A Safe Place for Science, a program aimed at hosting US researchers dismissed, censored, or limited by Trump’s policies. This project is backed with an investment of approximately €15 million.

Along the same lines, the Max Planck Society in Germany has announced the creation of the Max Planck Transatlantic Program, whose purpose is to establish joint research centers with US institutions. “Outstanding investigators who have to leave the US, we will consider for director positions,” the society’s director Patrick Cramer said in a speech discussing the program.

Spain seeks a leading role

Juan Cruz Cigudosa, Spain’s secretary of state for science, innovation, and universities, has stressed that Spain is also actively involved in attracting global scientific talent, and is prioritizing areas such as quantum biotechnology, artificial intelligence, advanced materials, and semiconductors, as well as anything that strengthens the country’s technological sovereignty.

To achieve this, the government of Pedro Sánchez has strengthened existing programs. The ATRAE program—which aims to entice established researchers into bringing their work to Spain—has been reinforced with €45 million to recruit scientists who are leaders in strategic fields, with a special focus on US experts who feel “looked down upon.” This program is offering additional funding of €200,000 euros per project to those selected from the United States.

Similarly, the Ramón y Cajal program—created 25 years ago to further the careers of young scientists—has increased its funding by 150 percent since 2018, allowing for 500 researchers to be funded per year, of which 30 percent are foreigners.

“We are going to intensify efforts to attract talent from the United States. We want them to come to do the best science possible, free of ideological restrictions. Scientific and technological knowledge make us a better country, because it generates shared prosperity and a vision of the future,” said Cigudosa in a statement to the Spanish international news agency EFE after the announcement of the Choose Europe for Science program.
