In tribute to Kendall, {Matt} Pinfield wrote, "Dave was one of the true believers. Long before alternative music found its way into the mainstream, he was there every week on 120 Minutes, introducing people to bands that would go on to define an era. He didn't just host a show. He gave a home to music that deserved to be heard. He loved the music, respected the artists, and connected with fans in a way that always felt authentic. That's a rare gift."

Kendall had relocated to Bangkok in the past decade; obit from the Bangkok Post here. "By far the most important thing about 120 Minutes was that it acted as a distribution channel for organic musical produce, if you will," Dave Kendall, the show's former host and producer who first pitched the show to MTV, wrote via email. "The only other outlet for non-mainstream music at the time was a few local college radio stations, because unlike in the UK, mainstream US radio stations were not open to new ideas." I found a list of 120 Minutes episodes here!

Today, we're excited to announce the open-source release of Microsoft Comic Chat, the chat client that automatically turned conversations within Internet Relay Chat (IRC) into comic panels featuring illustrated characters, speech bubbles, and expressions, and helped introduce the world to a little font called Comic Sans.
[David "DJ" Kurlander], Tim Skelly, and David Salesin published a paper on the technology in Comic Chat at SIGGRAPH '96
The visual world of Comic Chat was the work of Jim Woodring, a highly regarded independent comic artist whose characters gave the software its distinctive look.

We zijn boos op de Duitsers. Dat zijn we best wel eens vaker geweest maar je kunt stellen dat ze het nu wel heel bont maken. Dat alles wat leuk is verboden of onmogelijk moet worden gemaakt zijn we in eigen land gewend, maar we konden altijd nog naar het oosten rijden om daar, enkele meters voorbij de grens, pallets peuken in te slaan voor weinig doekoe in zo'n gezellige, daar speciaal voor ons Nederlanderse paupers neergeplempte peukenplaza. Zo konden we tenminste betaalbaar alle crises van ons af roken, meespelen in de longkankerloterij zonder daar eerst een nier voor te moeten verkopen. Maar die hobby gaat dus: in rook op. Duitsland gaat de accijnzen stapsgewijs verhogen, in 4 jaar tijd worden de Duitse peuken bijna net zo duur als in Nederland. Althans, als de peukprijzen hier tegen die tijd niet rond de 80 euro per pakje liggen. Dit is misschien wel het ergste wat Duitsland ooit heeft gedaan. Wij zoeken wel een adresje op de zwarte (longen)markt.

Mooi was die tijd

This video from Kurzgesagt is a great little primer on how the human brain stores memories.

Memory is one of the strangest abilities you possess. Your brain uses an incredibly complex biological system to preserve moments from your past that no longer exist, allowing you to revisit experiences from years ago. But memories are not always recordings of reality. In fact, every time a memory comes under the spotlight of your attention, it can melt and change a tiny bit.

What exactly is a memory, how is a moment in time stored inside your brain, and why does remembering something slowly rewrite the story of your life?

Deranged billionaires and their syndromes (permalink)

The theory of markets goes like this: even the best of us can fall prey to selfishness and rationalization, so let's arrange society so that people acting on their most selfish impulses end up producing benefit for all of us. That'll be easier and more reliable than convincing everyone to be more generous.

How do you arrange society so that selfishness produces public benefit? With markets. Faced with relentless competition, the most effective way to accumulate and retain wealth is by striving to make your wares cheaper and better. In a competitive labor market, we can secure fair treatment for workers without labor law or unions – bosses who treat their workers badly will lose them to better bosses. Just "align the incentives" and let markets do the rest.

This is an area where there's broad overlap between the left and the right. Chapter one of The Communist Manifesto is Marx and Engels' love letter to the incredible power of markets to improve everyone's material conditions by increasing production while lowering costs:

https://www.nytimes.com/2022/10/31/books/review/a-spectre-haunting-china-mieville.html?unlocked_article_code=1.yFA.YcmQ.KuTFFpUAnlmt&smid=url-share

Meanwhile, over in Wealth of Nations, Adam Smith comes to the same conclusion:

It is not from the benevolence of the butcher, the brewer, or the baker, that we expect our dinner, but from their regard to their own interest. We address ourselves, not to their humanity but to their self-love, and never talk to them of our own necessities but of their advantages.

In other words: if you get the incentives right, then even the greediest baker will resist the temptation to fill his loaves with sawdust and gravel. The greedier he is, the more he'll strive to make his bread cheap and delicious, because that will let him sell as many loaves as possible, thus maximizing his own wealth.

It's not exactly horseshoe theory vindicated, but if you squint just right, you'll see both communists and capitalists agreeing on this one thing: if you want the bourgeoisie to bend its efforts to producing something that the rest of us can benefit from, you'll get further by appealing to their fear and greed than by trusting in their munificence.

This is how you can have both leftists and market true believers coming onto the same side on antitrust: they may not both exactly agree that the best way to run things is by appealing to capitalists' fear of being dethroned by a competitor, but they absolutely agree that the worst way to run things is to simply trust in capitalists' generosity.

They're right, of course. As Lina Khan likes to say, companies that are too big to fail become too big to jail, and thus too big to care. If you doubt it, consider this internal email sent by an Apple executive insisting that the company is wasting money by making iPhones that are too good, and counseling a corporate strategy of deliberate shittiness:

In looking at it with hindsight, I think going forward we need to set a stake in the ground for what features we think are 'good enough' for the consumer. I would argue we're already doing more than what would have been good enough. But we find it very hard to regress our product features YOY [year over year]." Existing features "would have been good enough today if we hadn't introduced [them] already," and "anything new and especially expensive needs to be rigorously challenged before it's allowed into the consumer phone.

https://www.justice.gov/d9/2024-06/423137.pdf

Policymakers can assume the profit motive, but they have to craft the conditions under which that motive is shaped by competitive anxiety to produce quality goods and services at a fair price.

Anyone who believes in markets must also tacitly believe that successful market participants don't believe in markets. They should understand that capitalists hate capitalism, that every pirate yearns to be an admiral. They should understand that capitalism's winners only defend disruption when they're the ones doing the disrupting. They should understand that profits are only good when you're a scrappy challenger, but once you've conquered the market, every capitalist seeks to become a feudal lord, converting profits to rents and insulating themselves from an exhausting life of constant competition:

https://pluralistic.net/2023/09/28/cloudalists/#cloud-capital

The (smart) defenders of markets do understand this, but they face a dilemma. By definition, the benefactors with the most money and power to contribute to their think-tanks, university economics departments, conferences and publications are the rentiers – the billionaires who've shored up their fortunes with Warren Buffet's beloved "moats and walls." They're the blitzscaling billionaires who thrive on predatory acquisitions and high capital costs that prevent new market entrants from challenging their incumbency and its easy profits. They're the pirates who've become admirals.

As Upton Sinclair famously quipped, "It is difficult to get a man to understand something, when his salary depends on his not understanding it." When your right-wing, "pro-market" think-tank depends on the largesse of someone who made their money by capturing a market, capturing its regulators, and capturing its labor force, you need to tie yourself into some very weird knots to explain why your market advocacy shouldn't start with stripping your funders of their power, wealth and position.

This is pretty much the entire edifice of neoclassical economics. There's the "consumer welfare" theory of antitrust, that says that monopolies are efficient and insists that an inefficient monopoly would immediately tempt new competitors into the market who would compete away the monopolist's advantage:

https://pluralistic.net/2025/11/06/vertical-blinds/#invest-dont-acquire

"Consumer welfare" is a perfect apologetic because it contains a lurking syllogism: it holds that "inefficient monopolies" will always bring forth competitors who trash their margins, which means that any actual monopoly we see in the wild must be efficient. If it wasn't, it would have been competed out of existence by now. QED. This means that you can be a "pro-market" think-tank and take infinite money from monopolists without any contradiction: by definition, any monopolist with extra cash on hand to fund your PR blitz on its behalf must be efficient, otherwise it would have gone broke.

This is the structure of so many of economics' "empirical, scientific" theories that boil down to new ways of saying, "Actually, your boss is right."

Take "revealed preferences," the idea that people's actions are a better indicator of their preferences than the things they say they prefer. While this theory has a certain superficial plausibility, it can really only be embraced by people who have suffered the highly specific neurological injury you get by taking an economics degree: an injury that makes you incapable of perceiving or reasoning about power.

To fully embrace "revealed preferences" is to observe someone who has just sold their kidney to make rent and exclaim, "Look at this person with a revealed preference for only having one kidney":

https://pluralistic.net/2026/03/30/players-of-games/#know-when-to-fold-em

Then there's the right's conception of regulatory capture. When you think of "regulatory capture," you might picture a company or sector that has grown so powerful that it can boss the government around, so that it can abuse you with impunity. But for a neoclassical, "regulatory capture" isn't the result of too much corporate power – it's the result of too much state power. If states have the ability to do real things (the theory goes), then capitalists will do everything they can to take over the state and use it to punish their competitors, so the only answer is to eliminate state capacity altogether:

https://pluralistic.net/2022/06/05/regulatory-capture/

And finally, there's "meritocracy," which is a way of dressing up the Puritans' concept of divine providence as a scientific theory about how society must work. Puritans insisted that their god reached down into the human realm to elevate the truly virtuous among us, and that this divine favor could be discerned in the way that wealth and power were distributed among us. The rich and powerful were god's "elect." You could tell this was true, because they were rich and powerful. The corollary is that the poor and downtrodden are disfavored by god, and must therefore lack some virtue that the rich and powerful possess.

This same syllogistic thinking underpins the economic doctrine of "meritocracy," which holds that markets are giant computers that process uncountable trillions of decisions we all make about what to buy and sell and at what price, seeking out the "correct" price for every commodity and also elevating the people who are best at allocating capital in ways that arrive at the best prices for the best goods. Just as a Puritan believes that wealth is evidence of virtue, a hewer to economic orthodoxy believes the meritocratic system graces the best among us, giving them control over our lives by allowing them to "allocate capital" to create or destroy jobs, or entire firms, or whole sectors of the economy. You can tell they're the right people to do be doing this because the market chose them – if they were bad capital allocators, they'd have gone broke by now. QED.

When capital allocators' kids end up allocating capital too, well, that just shows that "merit" is a heritable trait and the people who have it are born to rule over us. Meritocracy cashes out to a eugenic belief in royal blood and royal dynasties. We know King Arthur was suited to rule us because he pulled a sword out of a stone, and we know Bill Gates is suited to rule over us because he pulled a fortune out of an operating system:

https://pluralistic.net/2025/05/20/big-cornflakes-energy/#caliper-pilled

Consumer welfare, revealed preferences, regulatory capture and meritocracy are just some of the ways that capitalism's alleged defenders cooked up to insist that they love the competitive discipline imposed by markets while being totally dependent on self-described capitalists who have utterly escaped from that discipline and have committed to doing everything in their power to prevent themselves from ever coming under any form of constraint.

These champions of "free markets" have spent decades defending policies like noncompetes, which makes it a crime for a fast-food worker to quit their job at Wendy's and take a job at the McDonald's across the street in order to get a $0.25/hour raise:

https://pluralistic.net/2025/09/09/germanium-valley/#i-cant-quit-you

They defend anticircumvention laws that make it a literal felony for you to install someone else's app store on your phone or put someone else's ink in your printer:

https://memex.craphound.com/2012/01/10/lockdown-the-coming-war-on-general-purpose-computing/

They somehow believe that value arises when the best among us are forced to contend with the stark terror of losing everything to a competitor, but also that there is a group of people who are so perfect, so virtuous and brilliant that they do not need this kind of goad to prod them into action. Indeed, these genetic sports and generational talents are so amazing that to force them to sully themselves with grubby competition is to deny us all the fruits of their genius.

Who are these people? Why, they're billionaires of course. All billionaires: after all, if providence and the market's invisible hand has seen fit to bestow nine or more zeroes upon someone, that is an indicator of 10^9 times more virtue than someone with only a dollar to their name. But especially: intellectual billionaires, the kinds of "curious" billionaires who write books, give lectures, and (especially), make gigantic cash donations to think-tanks, university economics departments, conferences and journals.

Billionaires like Peter Thiel and Elon Musk, in other words.

These are the billionaires that capitalism's (alleged) defenders are caping for when they deplore "billionaire derangement syndrome," and fret that candidates for office now routinely cite enmity for billionaires in their campaign materials:

https://marginalrevolution.com/marginalrevolution/2026/07/andrew-hall-is-on-a-roll.html

But as Tim O'Reilly writes, these billionaire-defending intellectuals always told us that markets would protect us from the madness of kings, by constraining the folly of the wealthy and powerful through the discipline of competition. Meanwhile, those billionaires were busily transforming themselves into kings, unshackled from rules, morals or consequences:

https://www.economist.com/by-invitation/2026/07/12/elon-musk-is-building-a-form-of-capitalism-that-adam-smith-would-hate

Reflecting on this, the political scientist Henry Farrell notes that the most vocal defenders of billionaireism – the Musks and Thiels of the world – never made a secret of their desire to become kings and insulate themselves from markets and discipline of every kind, and they've grown brazen. Musk makes social media posts deploring the very idea of elections, agreeing with the idea that only "makers" should be allowed to vote and that "takers" should not, because "universal suffrage leads to universal suffering":

https://nitter.net/elonmusk/status/2073312715985309698

As for Thiel, he has long openly advocated the idea that there exists among us a latent aristocracy who do not need the discipline of markets to keep them from lapsing into folly or self-dealing. These people – born to found tech startups and to rule – are nonconformists who, in Thiel's writing, are "the most important" and "should be let off the hook":

https://blakemasters.tumblr.com/post/24578683805/peter-thiels-cs183-startup-class-18-notes

Thiel makes no bones about his idea that people who have the right stuff should be exempted from any constraint. He writes "capitalism and competition are opposites." Rather than compete, Thiel says the true entrepreneur should seek to establish a monopoly, because "Monopolists can afford to think about things other than making money; non-monopolists can’t…Only one thing can allow a business to transcend the daily brute struggle for survival: monopoly profits."

It's not that Thiel opposes constraints per se – he clearly thinks that most of us should operate under constraints – constraints that are dreamed up and enforced by people like him. Those people are born to rule: they emerged from a lucky orifice, in possession of lucky genes. How can we tell they were born to rule? Because they're ruling. If they weren't born to rule, they wouldn't be in a position to rule. As ever, a syllogism solves all our ideological and existential problems.

Thiel lives in what Naomi Klein would call "the mirror world." While counterculturists have long celebrated misfits and communities of nonconformists, they were invested in the idea of a space protected from power, where weirdos could let their freak flags fly:

https://pluralistic.net/2023/09/05/not-that-naomi/#if-the-naomi-be-klein-youre-doing-just-fine

But Thiel's version of this is to celebrate the "nonconformists" whose heterodox belief is that labor, privacy, finance and consumer protection laws shouldn't apply to them. He wants to protect those people so they can wield power. They should form "mafias" (like the "Paypal mafia") not solidaristic affinity groups. As Farrell writes:

Entrepreneurial risk taking can be awesome; weird people are often more likely to be original; densely linked communities have many advantages. Furthermore, I would guess that none of these factors was sufficient on its own to precipitate the madness of princes that we see today. It is perfectly possible that they would have worked together in much more benign ways under different external circumstances. But we are in the world we’re in: one where the boundless appetites and irrationalities of a small number of billionaires seem increasingly incompatible with the need to maintain a stable civil society.

A new would-be aristocracy was always the visible trajectory of these guys. The only people who couldn't see it were the think-tankies they funded to write papers explaining that their paymasters didn't need market discipline to keep them from sinking into folly or attempting to overthrow democracy.

Today, these Renfields clutch their pearls at the "demonization" of the ultra-rich, calling it "billionaire derangement syndrome." But the only "billionaire derangement syndrome" that matters is the syndrome that affects billionaires and convinces them that they are above any discipline or rules.

Astronomers have detected an atmosphere around a rocky exoplanet in the habitable zone of its star for the first time in history, signalling a major breakthrough in the search for alien life, according to a study published on Thursday in Science. 

The planet, known as LHS 1140-b, is about 5.6 times more massive than Earth and orbits a small dwarf star about 48 light years from our solar system. While scientists have discovered atmospheres around many giant gas planets in our galaxy—and even a few rocky exoplanets outside the habitable zone—the new detection of helium in the skies of LHS 1140-b marks the first direct evidence that a habitable-zone rocky world can host an atmosphere, which is a critical factor for assessing their potential to support life.

“For rockier Earth-like planets, it has been a huge challenge in the field to detect any atmospheres at all,” said Collin Cherubim, a NASA Hubble Fellow at the University of Chicago, in a call with 404 Media. “This has been a huge question in the field that so much time and energy has been devoted to answering.”

 

The new discovery “is really the first claim ever of any rocky exoplanet atmosphere in the habitable zone that could potentially have liquid water and really support life,” added Cherubim, who conducted the research while he was a PhD student at Harvard University. “That's what sets it apart and makes it really exciting.”

Scientists have previously inferred that some rocky exoplanets in the habitable zone might have atmospheres based on indirect evidence, such as measurements that show that their day and night temperatures are more moderate than expected, which could be explained either by an atmosphere, or other planet-wide effects. However, spotting an atmosphere around these rocky worlds is tricky because they tend to be so small compared to their stars, which is a challenge for precision observations.

Cherubim came at the problem with a new approach: He first developed theoretical models of rocky exoplanets that focused on mass fractionation, a process by which lighter molecules and atoms in the atmosphere escape into space, while heavier ones are left behind. These simulations predicted a new type of planet with thick skies closer to the surface, and a thinner upper atmosphere that allows helium to escape to space.

“Hydrogen is the lightest element and it's the easiest to blow off into space,” Cherubim explained. “My model was predicting that if your planet is in this sweet spot where you're blowing enough hydrogen away, but not too much that you're dragging helium, which is a bit heavier, along with it, then you can actually create a helium-dominated atmosphere over time.” 

“This is a newly-predicted class of planets, which should have very unique chemistry,” he added. 

Cherubim realized that this escaping helium might be detectable from Earth, and that the LHS 1140 system would be a prime candidate to test out the hypothesis. To that end, the team observed LHS 1140-b and another planet in the system, LHS 1140-c, over the course of 2024 and 2025 with the Warm Infrared Echelle (WINERED) Spectrograph on the Magellan Observatory in Chile.

The 2024 results revealed a strong signal of helium at LHS 1140-b, but no detection in 2025, which may mean that the helium escape varies over time. The team predicts that the planet has probably had its atmosphere for billions of years. The other planet, LHS 1140-c, did not show any signs of an atmosphere, which was also expected based on its orbit and characteristics.

The momentous discovery proves that atmospheres can exist around rocky worlds, including around dwarf stars, which are far more common than more massive stars like the Sun. Cherubim and his colleagues think it’s quite likely that LHS 1140-b has large amounts of liquid water on its surface, another key ingredient for life as we know it on Earth.

“When we think about habitability, we think about three high-level things,” Cherubim said. “We think the planet needs to be rocky for the most part. It can't be a gas-rich thing where the surface is molten, or like Jupiter where it's just all gas. It's got to be the right temperature to support surface liquid water, at least for Earth-like life, and it needs an atmosphere to hold that water in and to shield the surface from radiation.” 

“With this discovery, we now know LHS 1140-b has all three of those things, which is really exciting,” he added. “And it just happens to be a very nearby system to Earth, so it's very accessible.”

Whether alien life exists on LHS 1140-b remains an open question, but scientists have already been looking for signs of life, known as biosignatures, in its skies using the Hubble Space Telescope and the James Webb Space Telescope. So far, the search hasn’t turned up any obvious signs of life, but future efforts may be able to peer at this world in more detail. 

“I think this is the best place to be looking for biosignatures,” Cherubim concluded. “We're really excited to see what comes out of that.”
