Restoring a 100-Year-Old Animated Film

12:53 Add Comment

You’ve probably seen the work of animation pioneer Max Fleischer; he made the old Popeye, Superman, Betty Boop, and Koko the Clown cartoons waaaay back in the early-to-mid 20th century. Films from back then are often not well-preserved, so when a copy is discovered in a film library or private collection, great care must be exercised in restoring the film for future generations to enjoy.

This video follows the restoration process of Fleischer’s 1924 Koko the Clown film Birthday, from scanning a 35mm print from 1930 to the digital retouching. The fully restored print doesn’t seem to be online anywhere, but you can see a couple of before-and-after comparisons here and here.

The Origin of Joy Division's Unknown Pleasures Album Cover Art

Joy Division Unknown Pleasures

For Scientific American, Jen Christiansen tracks down where the iconic image on the cover of Joy Division’s Unknown Pleasures came from. Designer Peter Saville found the image, a stacked graph of successive radio signals from pulsar CP 1919, in a 1977 astronomy encyclopedia but it actually originated in a 1970 Ph.D. thesis.

By now I had also combed through early discovery articles in scientific journals and every book anthology on pulsars I could get my hands on to learn more about early pulsar visualizations. The more I learned, the more this descriptor in the 1971 Ostriker caption began to feel significant; “computer-generated illustration.” The charts from Bell at Mullard were output in real time, using analogue plotting tools. A transition in technology from analogue to digital seemed to have been taking place between the discovery of pulsars in 1967 to the work being conducting at Arecibo in 1968 through the early 1970’s. A cohort of doctoral students from Cornell University seemed to be embracing that shift, working on the cutting edge of digital analysis and pulsar data output. One PhD thesis title from that group in particular caught my attention, “Radio Observations of the Pulse Profiles and Dispersion Measures of Twelve Pulsars,” by Harold D. Craft, Jr. (September 1970).

When a star gets old and fat, it explodes in a supernova, leaving a neutron star in its wake. Neutron stars are heavily magnetized and incredibly dense, approximately two times the mass of the Sun packed into an area the size of the borough of Queens. That’s right around the density of an atomic nucleus, which isn’t surprising given that neutron stars are mostly composed of neutrons. A teaspoon of neutron star would weigh billions of tons.

A pulsar is a neutron star that quickly rotates. As the star spins, electromagnetic beams are shot out of the magnetic poles, which sweep around in space like a lighthouse light. Pulsars can spin anywhere from once every few seconds to 700 times/second, with the surface speed approaching 1/4 of the speed of light. These successive waves of electromagnetic pulses, arriving every 1.34 seconds, are what’s depicted in the stacked graph. Metaphorical meanings of its placement on the cover of a Joy Division record are left as an exercise to the reader.

How Noiseless Props Are Made For Movies And TV Shows

12:53 Add Comment

Insider has been doing a whole series of videos on how movie props are made (view the entire thing here) and I found this one on how prop makers rely on noiseless props to be particularly interesting. To cut down on distracting on-set noise (so dialogue can be heard, for instance), they swap racquetball balls for pool balls, silicon chunks for ice cubes, and paper bags made out of coffee filter material for real paper bags. So weird to watch those objects in action without their usual sounds. (thx, caroline)

Tapping the Vast Renewable Energy of the Yellowstone Supervolcano

Tapping the Vast Renewable Energy of the Yellowstone Supervolcano

09:53 Add Comment

geological map of the Yellowstone Caldera

The first few sentences of the abstract for this paper from the scientific journal Renewable Energy contain a twist in the middle that’s worthy of M. Night Shyamalan:

The USA is confronted with three epic-size problems: (1) the need for production of energy on a scale that meets the current and future needs of the nation, (2) the need to confront the climate crisis head-on by only producing renewable, green energy, that is 100% emission-free, and (3) the need to forever forestall the eruption of the Yellowstone Supervolcano. This paper offers both a provable practical, novel solution, and a thought experiment, to simultaneously solve all of the above stated problems.

If you don’t know about the supervolcano lurking under Yellowstone National Park, now’s your chance to learn more. Here’s Bill Bryson from his book A Short History of Nearly Everything:

Yellowstone, it turns out, is a supervolcano. It sits on top of an enormous hot spot, a reservoir of molten rock that rises from at least 125 miles down in the Earth. The heat from the hot spot is what powers all of Yellowstone’s vents, geysers, hot springs, and popping mud pots. Beneath the surface is a magma chamber that is about forty-five miles across — roughly the same dimensions as the park — and about eight miles thick at its thickest point. Imagine a pile of TNT about the size of Rhode Island and reaching eight miles into the sky, to about the height of the highest cirrus clouds, and you have some idea of what visitors to Yellowstone are shuffling around on top of. The pressure that such a pool of magma exerts on the crust above has lifted Yellowstone and about three hundred miles of surrounding territory about 1,700 feet higher than they would otherwise be. If it blew, the cataclysm is pretty well beyond imagining. According to Professor Bill McGuire of University College London, “you wouldn’t be able to get within a thousand kilometers of it” while it was erupting. The consequences that followed would be even worse.

Back to the paper. The authors are proposing to generate massive amounts of energy from the supervolcano — “well over 11 Quadrillion Watt hours of electrical energy” per year:

Through a new copper-based engineering approach on an unprecedented scale, this paper proposes a safe means to draw up the mighty energy reserve of the Yellowstone Supervolcano from within the Earth, to superheat steam for spinning turbines at sufficient speed and on a sufficient scale, in order to power the entire USA. The proposed, single, multi-redundant facility utilizes the star topology in a grid array pattern to accomplish this. Over time, bleed-off of sufficient energy could potentially forestall this Supervolcano from ever erupting again.

I mean, this actually sounds like a great idea if it could be done safely, without ruining the park and, you know, accidentally blowing shit up. As of 2016, Iceland generated 65% of its energy from geothermal sources — the US could certainly stand to lean more on geothermal.

ChatGPT Made Me Cry and Other Adventures in AI Land

ChatGPT Made Me Cry and Other Adventures in AI Land

12:53 Add Comment

ChatGPT answers a question about what kottke.org is

[Yesterday I spent all day answering reader questions for the inaugural Kottke.org Ask Me Anything. One of them asked my opinion of the current crop of AI tools and I thought it was worth reprinting the whole thing here. -j]

Q: I would love to know your thoughts on AI, and specifically the ones that threaten us writers. I know you’ve touched on it in the past, but it seems like ChatGPT and the like really exploded while you were on sabbatical. Like, you left and the world was one way, and when you returned, it was very different. —Gregor

A: I got several questions about AI and I haven’t written anything about my experience with it on the site, so here we go. Let’s start with two facts:

  1. ChatGPT moved me to tears.
  2. I built this AMA site with the assistance of ChatGPT. (Or was it the other way around?)

Ok, the first thing. Last month, my son skied at a competition out in Montana. He’d (somewhat inexplicably) struggled earlier in the season at comps, which was tough for him to go through and for us as parents to watch. How much do we let him figure out on his own vs. how much support/guidance do we give him? This Montana comp was his last chance to get out there and show his skills. I was here in VT, so I texted him my usual “Good luck! Stomp it!” message the morning of the comp. But I happened to be futzing around with ChatGPT at the time (the GPT-3.5 model) and thought, you know, let’s punch this up a little bit. So I asked ChatGPT to write a good luck poem for a skier competing at a freeski competition at Big Sky.

In response, it wrote a perfectly serviceable 12-line poem with three couplets that was on topic, made narrative sense, and rhymed. And when I read the last line, I burst into tears. So does that make ChatGPT a soulful poet of rare ability? No. I’ve thought a lot about this and here’s what I think is going on: I was primed for an emotional response (because my son was struggling with something really important to him, because I was feeling anxious for him, because he was doing something potentially dangerous, because I haven’t seen him too much this winter) and ChatGPT used the language and methods of thousands of years of writing to deliver something a) about someone I love, and b) in the form of a poem (which is often an emotionally charged form) — both of which I had explicitly asked for. When you’re really in your feelings, even the worst movie or the cheesiest song can resonate with you and move you — just the tiniest bit of narrative and sentiment can send you over the edge. ChatGPT didn’t really make me cry…I did.

But still. Even so. It felt a little magical when it happened.

Now for the second part. I would say ChatGPT (mostly the new GPT-4 model), with a lot of hand-holding and cajoling from me, wrote 60-70% of the code (PHP, Javascript, CSS, SQL) for this AMA site. And we easily did it in a third of the time it would have taken me by myself, without having to look something up on Stack Overflow every four minutes or endlessly consulting CSS and PHP reference guides or tediously writing tests, etc. etc. etc. In fact, I never would have even embarked on building this little site-let had ChatGPT not existed…I would have done something much simpler and more manual instead. And it was a *blast*. I had so much fun and learned so much along the way.

I’ve also been using ChatGPT for some other programming projects — we whipped the Quick Links into better shape (it can write Movable Type templating code…really!) and set up direct posting of the site’s links to Facebook via the API rather than through Zapier (saving me $20/mo in the process). It has really turbo-charged my ability to get shit done around here and has me thinking about all sorts of possibilities.

I keep using the word “we” here because coding with ChatGPT — and this is where it starts to feel weird in an uncanny valley sort of way — feels like a genuine creative collaboration. It feels like there is a “someone” on the other side of that chat, a something that’s really capable but also needs a lot of hand-holding. Just. Like. Me. There’s a back and forth. We both screw up and take turns correcting each other’s mistakes. I ask it please and tell it thank you. ChatGPT lies to me; I gently and non-judgmentally guide it in a more constructive direction (as you would with a toddler). It is the fucking craziest weirdest thing and I don’t really know how to think about it.

There have only been a few occasions in my life when I’ve used or seen some new technology that felt like magic. The first time I wrote & ran a simple BASIC program on a computer. The first time I used the web. The first time using a laptop with wifi. The first time using an iPhone. Programming with ChatGPT over the past few weeks has felt like magic in the same way. While working on these projects with ChatGPT, I can’t wait to get out of bed in the morning to pick up where we left off last night (likely too late last night), a feeling I honestly have not consistently felt about work in a long time. I feel giddy. I feel POWERFUL.

That powerful feeling makes me uneasy. We shouldn’t feel so suddenly powerful without pausing to interrogate where that power comes from, who ultimately wields it, and who it will benefit and harm. The issues around these tools are complex & far-reaching and I’m still struggling to figure out what to think about it all. I’m persuaded by arguments that these tools offer an almost unprecedented opportunity for “helping humans be creative and express themselves” and that machine/human collaboration can deepen our understanding and appreciation of the world around us (as has happened with chess and go). I’m also persuaded by Ted Chiang’s assertion that our fears of AI are actually about capitalism — and we’ve got a lot to fear from capitalism when it comes to these tools, particularly given the present dysfunction of US politics. There is just so much potential power here and many people out there don’t feel uneasy about wielding it — and they will do what they want without regard for the rest of us. That’s pretty scary.

Powerful, weird, scary, uncanny, giddy — how the hell do we collectively navigate all that?

(Note: ChatGPT didn’t write any of this, nor has it written anything else on kottke.org. I used it once while writing a post a few weeks ago, basically as a smart thesaurus to suggest adjectives related to a topic. I’ll let you know if/when that changes — I expect it will not for quite some time, if ever. Even in the age of Ikea, there’s still plenty of handcrafted furniture makers around and in the same way, I suspect the future availability of cheap good-enough AI writing/curation will likely increase the demand and value for human-produced goods.)

Wes Anderson’s Asteroid City

09:53 Add Comment

The top two comments on YouTube sum this trailer for Asteroid City up pretty well: “Just when you don’t think it can get more Wes Anderson, it gets more Wes Anderson.” and “You know a Wes Anderson movie is a Wes Anderson movie, but you can’t really describe a Wes Anderson movie to someone who has never seen a Wes Anderson movie.” Here’s the synopsis:

The itinerary of a Junior Stargazer/Space Cadet convention (organized to bring together students and parents from across the country for fellowship and scholarly competition) is spectacularly disrupted by world-changing events.

Does it even matter to know this? At this point, you’re either throwing money at the screen after watching this trailer (*raises hand*) or you’re just not interested. For those in the former camp, Asteroid City opens in theaters on June 16.

Henri Cartier-Bresson’s Forgotten Photographs of New Jersey

black and white photo of kids running across the street in 70s New Jersey

black and white photo of a big box truck under a bridge

In 1975, famed French photographer Henri Cartier-Bresson traveled, at the behest of a public television station, to the US to take photographs of New Jersey.

The photographer felt that New Jersey’s anywhere-ness, its density and diversity, was “a kind of shortcut through America.” With that prompt, Evans assembled an itinerary. Cunningham picked up Cartier-Bresson in Manhattan around sunrise each day for three weeks and headed for the bridges and tunnels. They embedded with ambulance drivers in Newark and chicken farmers in West Orange. They visited suburban sprawl, horse country, pine barrens, swamps, seashore, beauty parlors, labs, nuclear facilities, jails, mansions. They once stayed overnight in a South Jersey motel, and Cartier-Bresson insisted that they flip a coin to determine who got the bed.

It was one of his final photo projects and because his photos were cropped for use on television (“a practice Cartier-Bresson viewed as sacrilege”), the project was not included in most catalogues of his work and was almost forgotten.

You can watch the resulting TV program from 1975 at the American Archive of Public Broadcasting.

Everything Is a Remix

09:53 Add Comment

Kirby Ferguson has released the final and “definitive” full-length version of his fantastic Everything is a Remix video series (transcript).

Memes are remixing. You take a photo, you repurpose it, then someone else tries it, then there’s a flood of everyone trying out combinations, including remixing other memes.

When you take something old and use it in something new, that’s remixing. It might just seem like just copying, but it’s actually something much more. Remixing can empower you be more creative.

Remixing allows us to make music without playing instruments, to create software without coding, to create bigger and more complex ideas out of smaller and simpler ideas.

You don’t need expensive tools to remix, you don’t need a distributor, you don’t even need skills or… good judgment. Everybody can remix and everybody does.

From our songs and games and movies and memes, to how we train computers to create, to the way we sense of reality, to the evolution of life itself, everything is definitely a remix.

Transcript of Raiders of the Lost Ark Brainstorming Session

Transcript of Raiders of the Lost Ark Brainstorming Session

07:55 Add Comment

Wow. In 1978, George Lucus gathered together Steven Spielberg and screenwriter Lawrence Kasdan to go over ideas for a film Lucas had wanted to make about a swashbuckling archeologist, i.e. Raiders of the Lost Ark. Their sessions were recorded and there’s a transcript available online.

Lucas - Now, several aspects that we’ve discussed before: The image of him which is the strongest image is the “Treasure Of Sierra Madre” outfit, which is the khaki pants, he’s got the leather jacket, that sort of felt hat, and the pistol and holster with a World War One sort of flap over it. He’s going into the jungle carrying his gun. The other thing we’ve added to him, which may be fun, is a bull whip. That’s really his trade mark. That’s really what he’s good at. He has a pistol, and he’s probably very good at that, but at the same time he happens to be very good with a bull whip. It’s really more of a hobby than anything else. Maybe he came from Montana, someplace, and he… There are freaks who love bull whips. They just do it all the time. It’s a device that hasn’t been used in a long time.

Spielberg - You can knock somebody’s belt off and the guys pants fall down.

Lucas - You can swing over things, you can…there are so many things you can do with it. I thought he carried it rolled up. It’s like a Samurai sword. He carries it back there and you don’t even notice it. That way it’s not in the way or anything. It’s just there whenever he wants it.

Spielberg - At some point in the movie he must use it to get a girl back who’s walking out of the room. Wrap her up and she twirls as he pulls her back. She spins into his arms. You have to use it for more things than just saving himself.

Lucas - We’ll have to work that part out. In a way it’s important that it be a dangerous weapon. It looks sort of like a snake that’s coiled up behind him, and any time it strikes it’s a real threat.

Kasdan - Except there has to be that moment when he’s alone with a can of beer and he just whips it to him.

Patrick Radden Keefe at the New Yorker read through the whole thing and has some highlights and general thoughts.

Over the intervening decades of enormous wealth and success, both Lucas and Spielberg have carefully tended their public images, so there is a voyeuristic thrill to seeing them converse in so unguarded a manner. As the screenwriters Craig Mazin and John August pointed out recently on the Scriptnotes podcast, one delight of reading the transcript is watching Spielberg throw out bad ideas, and then noting how Lucas gently shuts him down. Spielberg, who had sought to direct a Bond movie-and, astonishingly, been rejected-thought that their hero should be an avid gambler. Lucas replied that perhaps they shouldn’t overload him with attributes. (Lucas himself had briefly entertained, then mercifully set aside, the notion that his archaeologist might also be a practitioner of kung fu.) There’s a good reason we seldom get to spy on these conversations: really good spitballing, like improv comedy, requires a high degree of social disinhibition. So the writers’ room, like a therapist’s office, must remain inviolable.

Plastic Scrimshaw

09:53 Add Comment

For an exhibition entitled DEATH TO THE LIVING, Long Live Trash now on view at the Brooklyn Museum, artist Duke Riley takes trash that he’s collected on the beach and turns it into art — think mosaics made from bottle caps, bread bag clips, and tampon applicators. But his plastic scrimshaw creations are absolute genius:

scrimshaw art etched onto a plastic jug

scrimshaw art etched onto a plastic flamingo

Scrimshaw art was made by whalers in the 19th century by carving designs into the teeth, bones, and baleen of whales. Riley has cleverly adopted the practice using aesthetically similar white plastics, producing a series he calls the Poly S. Tyrene Maritime Museum. The NY Times:

As whalers often depicted the leaders and profiteers of their day, Riley portrays the C.E.O.s of chemical companies, plastic industry lobbyists and others he deems responsible for producing the devastating tonnages of single-use plastics that are engulfing our oceans and threatening our ecosystems. It’s a downer, but if you look closely there’s often a Riley twist of humor, like the seagull shown relieving itself on the head of a water bottle magnate.

You can see a few more of the plastic scrimshaw objects on the Brooklyn Museum’s Tumblr,at Atlas Obscura, and in-person at the Brooklyn Museum until mid-April. (thx caroline)

astounding image of the Sun

detail of an astounding image of the Sun

Good morning, sunshines! Well, amateur astrophotographer Andrew McCarthy has done it again. Collaborating with Jason Guenzel, he has produced this absolutely gobsmacking image of the Sun.

The aptly named “Fusion of Helios” is a fusion from the minds of two astrophotographers, Andrew McCarthy and Jason Guenzel. Using a custom-modified hydrogen alpha solar telescope, the combined data from over 90,000 individual images was jointly processed to reveal the layers of intricate details within the solar chromosphere. A geometrically altered image of the 2017 eclipse as an artistic element in this composition to display an otherwise invisible structure. Great care was taken to align the two atmospheric layers in a scientifically plausible way using NASA’s SOHO data as a reference.

I’ve included the full image and my favorite crop (the solar tornado the height of 14 Earths was a close second) above, but do yourself a big favor and check out the largest image available (which is still way smaller than the 140 megapixel final image they produced). If you’re curious about the process, here’s how McCarthy gets his Sun photos:

So how do I resolve atmospheric details, like spicules, prominences, and filaments? The trick is tuning the telescope to an emission line where these objects aren’t drown out by the bright photosphere. Specifically, I’m shooting in the Hydrogen-alpha band of the visible spectrum (656.28nm). Hydrogen Alpha (HA) filters are common in astrophotography, but just adding one to your already filtered telescope will just reduce the sun’s light to a dim pink disk, and using it without the aperture filter we use to observe the details on the photosphere will blind you by not filtering enough light. If you just stack filters, you still can’t see details. So what’s the solution?

A series of precisely-manufactured filters that can be tuned to the appropriate emission line, built right into the telescope’s image train does the trick! While scopes built for this purpose do exist (look up “coronado solarmax” or “lunt solar telescope” I employ a heat-tuned hydrogen alpha filter (daystar quark) with an energy rejection filter (ERF) on a simple 5” doublet refractor. That gives me a details up close look at our sun’s atmosphere SAFELY. I’ve made a few custom modifications that have helped me produce a more seamless final image, but am not *quite* yet ready to share them, but just the ERF+Quark on a refractor will get you great views.

Photography has always been a combination of technology, artistry, and wrangling whatever light you can get to best express the feeling that you’re going for — astrophotography certainly dials that wrangling up to 11.

Prints of this image (and some digital downloads) are available in various sizes from McCarthy and Guenzel.

Every day for three years, Iancu Barbarasa drew a flower for his partner and recently he compiled all the drawings into this lovely short film set to Chopin’s Minute Waltz. I loved his acknowledgement of his sources and influences:

Questlove once said that “all creative ideas are derivative of another.” My project would not exist (or at least not in this form) without the influences of: Katsuji Wakisaka, textile designer and founder of Sou·Sou, who has drawn over 10,000 postcards for his wife — Christoph Niemann’s work and also his short film “A Tribute to Maurice Sendak” — “Beyond Noh (Masks of our world)” short film by Patrick Smith — “Plante” short film by Reka Bucsi — and Philippa Perry’s “The Book You Wish Your Parents Had Read (and Your Children Will Be Glad That You Did)”. Last but not least, the end credits are a tribute to Hayao Miyazaki’s wonderful “My Neighbour Totoro” film.

A set of postcards featuring the flower drawings are available from Barbarasa’s shop.

Mattias Adolfsson’s Whimsical Illustrations

I’ve featured the work of Mattias Adolfsson before, but I ran across some of his marvelously dense & vaguely steampunk illustrations again the other day and wanted to point you in his direction once again.

The fantastical & whimsical nature of Adolfsson’s work reminds me of Mark Alan Stamaty, Richard Scarry, Shel Silverstein, and perhaps even a little Quentin Blake and Aardman.

Lego bricks and Impressionism are a natural pairing, and so Chinese artist Ai Weiwei has recreated Claude Monet’s massive Water Lilies triptych with 650,000 Lego bricks. Spanning nearly 50 feet across, the Lego sculpture is part of Ai’s upcoming show at the Design Museum in London. Here is a tantalizing behind-the-scenes view.

Ai has been creating Lego works for years now — including these Warhol-esque portraits and A Sunday on La Grande Jatte — and was even denied from buying bricks from the company at one point.

A Potential Major Discovery: An Aperiodic Monotile

09:53 Add Comment

an aperiodic monotile

The authors of a new preprint paper claim that they’ve discovered what’s called an aperiodic monotile, a single shape that can cover a two-dimensional space with a pattern that never repeats itself exactly. One of the authors, Craig Kaplan, explains on Mastodon:

How small can a set of aperiodic tiles be? The first aperiodic set had over 20000 tiles. Subsequent research lowered that number, to sets of size 92, then 6, and then 2 in the form of the famous Penrose tiles.

Penrose’s work dates back to 1974. Since then, others have constructed sets of size 2, but nobody could find an “einstein”: a single shape that tiles the plane aperiodically. Could such a shape even exist?

Taylor and Socolar came close with their hexagonal tile. But that shape requires additional markings or modifications to tile aperiodically, which can’t be encoded purely in its outline.

In a new paper, David Smith, Joseph Myers, Chaim Goodman-Strauss and I prove that a polykite that we call “the hat” is an aperiodic monotile, AKA an einstein. We finally got down to 1!

The full paper is here. You can play around with the tiles here & here and watch an animation of an infinite array of these monotiles.

If you’re looking for a quick explanation of what aperiodic tiling is, check out the first 20 seconds of this video:

What’s the Deal with Ozempic, the “Breakthrough” Diabetes and Weight-Loss Drug?

09:53 Add Comment

In the last several months, semaglutide, a drug originally developed to help manage type 2 diabetes, has been in the news for its “breakthrough” weight loss abilities. This video from Vox is a good overview of what the drug does and the interest & controversy around it.

Both Ozempic and Wegovy, Ozempic’s counterpart approved specifically for weight loss by the FDA, are brand names of a drug called semaglutide. Semaglutide is one of several drugs that mimics a crucial digestive hormone called glucagon-like peptide 1, or GLP-1. It amplifies a process our bodies perform naturally.

GLP-1 is released in our intestines when we eat, and there are receptors for the hormone in cells all over the body. In the pancreas, GLP-1 promotes the production of insulin and suppresses the production of glucagon. This helps insulin-resistant bodies, like those with type 2 diabetes or obesity, manage blood sugar levels. In the stomach, GLP-1 slows gastric emptying, extending the feeling of being full. In the brain, GLP-1 suppresses appetite, which also promotes satiety and curbs hunger, so we eat less.

Jia Tolentino wrote a long piece about semaglutide for the New Yorker this week: Will Ozempic Change How We Think About Being Fat and Being Thin?

But, as I kept reminding Ozempic-curious friends, these medications were designed for chronic conditions, obesity and diabetes. For people who are dealing with those conditions, Ozempic appears to create a path toward a healthy relationship to food. For those who aren’t, it might function more like an injectable eating disorder. As the side effects make clear, it’s not a casual thing to drastically alter your body’s metabolic process, and there is no large-scale data about the safety of these drugs when taken by people who are mainly interested in treating another chronic condition, the desire to be thin.

Julia Belluz wrote a piece for Vox on Obesity in the age of Ozempic and Eric Topol wrote about The New Obesity Breakthrough Drugs.

Update: In the shuffle of the last few months, I’d missed reading Paul Ford’s piece about “the post-hunger age”, A New Drug Switched Off My Appetite. What’s Left?

I can see my anxiety mirrored in the wave of reactions starting to appear — op-eds, TV segments, people explaining why it’s good, actually, that the vast majority of those using this drug lose a quarter of their body weight. On social media, fat activists are pointing out that our lives were worthy even without this drug. The wave of opinion will not crest for years.

And that’s fair because this is new — not just the drug, but the idea of the drug. There’s no API or software to download, but this is nonetheless a technology that will reorder society. I have been the living embodiment of the deadly sin of gluttony, judged as greedy and weak since I was 10 years old-and now the sin is washed away. Baptism by injection. But I have no more virtue than I did a few months ago. I just prefer broccoli to gloopy chicken. Is this who I am?

Even outside the context of drugs, I find the tension between accepting who you are verus trying to change some behavior you find unappealing is challenging to navigate — it’s somerthing that comes up in therapy a lot. (thx, anil)

The So-Called “Culture Wars”

11:53 Add Comment

Political cartoonist Jen Sorensen recently published this cartoon at The Nib about the harmful mischaracterization of human rights battles as mere “culture wars”.

a political cartoon by Jen Sorensen about the culture wars

Here’s what she wrote about it:

The term “culture wars” is used by many well-meaning people, including many progressive writers and activists I admire. It’s a convenient way to refer to a number of issues. But in this current political moment, I think it’s a highly misleading euphemism. What we are experiencing in America right now is an asymmetrical attack on basic freedoms — a fascist movement that thrives on targeting certain groups, erasing history, and spreading dangerous falsehoods through a vast media apparatus. To call this a “culture war” is to legitimize the contemporary GOP and its extremist counterparts as a coherent and authentic “culture” worthy of respect. This is a misuse of the concept of culture, creating a false equivalence between marginalized groups and those who would harm or eliminate them in a quest for ever more power.

Yeah, spot on. You can follow Sorensen’s work on Mastodon, The Nib, Daily Kos, and Patreon.

The Difficulty of Living in Exponential Time

The Difficulty of Living in Exponential Time

06:53 Add Comment

In a piece about how the pace of improvement in the current crop of AI products is vastly outstripping the ability of society to react/respond to it, Ezra Klein uses this cracker of a phrase/concept: “the difficulty of living in exponential time”.

I find myself thinking back to the early days of Covid. There were weeks when it was clear that lockdowns were coming, that the world was tilting into crisis, and yet normalcy reigned, and you sounded like a loon telling your family to stock up on toilet paper. There was the difficulty of living in exponential time, the impossible task of speeding policy and social change to match the rate of viral replication. I suspect that some of the political and social damage we still carry from the pandemic reflects that impossible acceleration. There is a natural pace to human deliberation. A lot breaks when we are denied the luxury of time.

But that is the kind of moment I believe we are in now. We do not have the luxury of moving this slowly in response, at least not if the technology is going to move this fast.

Covid, AI, and even climate change (e.g. the effects we are seeing after 250 years of escalating carbon emissions)…they are all moving too fast for society to make complete sense of them. And it’s causing problems and creating opportunities for schemers, connivers, and confidence tricksters to wreck havoc.

Great Art Explained: Georges Seurat’s A Sunday on La Grande Jatte

16:53 Add Comment

Say what you will about The Algorithms, but YouTube’s reliably informs this art history lover of every new episode of Great Art Explained and for that I am grateful. This latest episode is about the pointillist masterpiece by Georges Seurat, A Sunday on La Grande Jatte. I had a chance to see this painting in person last summer at The Art Institute of Chicago — spent quite a bit of time looking at it from all angles and distances — so this episode was the perfect accompaniment to that visit.

The lack of narrative means we really should look to the artist’s obsession with form, technique and theory — which is practically all he wrote about — and not to meaning or subject matter - which he didn’t write about at all. The painting is really his manifesto. His protagonists don’t have faces or body language, neither a history nor individuality. They are reduced to a hat, a corset, or a pet. They are just characters in his frieze. They exist only to give perfect balance to the composition.

Some paintings are designed for the viewer to “empathise with” but Seurat keeps us at arm’s length. We are not invited to “participate” in the promenade, and their psychological distance is clear. Both with their neighbors, and with us. It was ancient art that Seurat looked to — of Egypt and Greece. He once said that he “wanted to make modern people move about as they do on the Parthenon Frieze”, and placed them on canvases organized by harmonies of colour. It is what makes the painting so intriguing.

two kottke.org shirts, one black and one white, with a bright multi-colored 'hypertext' printed on them

In celebration of the site’s 25th anniversary, I’ve turned ordering back on for Kottke Hypertext Tees for the next day or so. Here’s what I wrote about them last month:

For much of the nearly 25-year lifespan of kottke.org, the site’s tagline has been “home of fine hypertext products”. I always liked that it felt olde timey and futuristic at the same time, although hypertext itself has become antiquated — no one talks of hypertextual media anymore even though we’re all soaking in it.

And so but anyway, I thought it would fun to turn that tagline into a t-shirt, so I partnered with the good folks at Cotton Bureau to make a fine “hypertext” product that you can actually buy and wear around and eventually it’ll wear out and then you can use it to wash your car. If you want to support the site and look good doing it, you can order a Kottke.org Hypertext Tee right now.

You can check out my original post for more details. These shirts were super popular (I sold almost 3X as many as I thought I would) so I figured I’d make them available again for folks who hadn’t seen them the first time around.

Kottke 25: It’s Membership Time!

08:53 Add Comment

neon sign that reads 'kottke.org memberships available inquire within'

Good morning! Tomorrow marks 25 years of blogging here at kottke.org and it’s been more than three months since I returned from my sabbatical, so I thought it would be a good time to:

a) Once again express my heartfelt thanks to those of you who have supported the site over the years by purchasing a membership. Kottke.org has been my full-time job since 2005, and I’ve said this many times before but: this membership support is essential in keeping the site running so smoothly, with few membership solicitations like this one, very minimal advertising, no popup newsletter sign-up forms, a full-text RSS feed w/ no ads, etc. etc. etc.

And perhaps nearest and dearest to my heart, member support keeps the site free, open, and available to everyone on an internet that is increasingly paywalled. It’s not difficult to imagine an alt-universe kottke.org with ads crammed into every bit of whitespace, email collection forms popping up on every visit, and half the site behind a members-only paywall. No shade to those who have gone that route to keep things running — I’d probably make more money with members-only content on Substack or whatever and that pull is tempting. But seriously, I love you folks so much for collectively keeping all of kottke.org on the open web. Thank you.

b) Cajole those of you who aren’t currently members to sign up for a membership today or, in the case of former members, to restart your memberships.1 I’m not going to give you the hard sell here — I listed some reasons to join in the preceding paragraphs and if you’re a regular reader, I don’t have to tell you the value you get from the site; you already know that for yourself. What I’m asking is: if you appreciate what I do here and you can manage it, please support the site by purchasing a membership.

—-

I also wanted to give you a brief update & behind-the-scenes about what happened with memberships during my sabbatical and in the months since I’ve returned. One of my biggest hesitations about taking time off from the site was losing revenue from both memberships and advertising. I was unsure how my announcement would be received and was worried I was somehow idiotically crashing this tiny, fragile business of mine onto the shoals. After probably too much thinking/anxiety about it, I decided I needed the break more than the revenue and that I could build memberships back up again after I returned. It was a risk, but one I decided I needed to take.

When I announced the sabbatical back in May 2022, something completely unexpected happened: memberships went up. People signed up or increased their membership levels specifically to support me taking time off, and very few people cancelled. I actually burst into tears when I checked my member dashboard and saw this happening in the hours after the announcement. That display of support — and the hundreds of emails2 I received — allowed me the space and peace of mind I needed to fully disengage and disconnect from my work here to reflect and recharge (and, like, get some chores done around the house for a change).

Fast forward to the end of October. I wasn’t quite ready to return to work yet. Because I’d launched the membership program back in November of 2016, I’d say about 60-70% of all annual memberships still renew in early November.3 You may be able to guess what happened: despite a brief update on my plans to return soon, many people cancelled their memberships. That decline has continued in the following months, even after I returned to work. In fact, there are about 10% fewer members now than there were right before I logged off in May. So, the drop-off in revenue I expected when I took a break was just delayed by a few months.

When I returned at the beginning of December, I wanted to knuckle down and focus on the site and not bug you about memberships. Ship first, worry about revenue later. Now that I’ve been back at it full-time for three-and-a-half months, I’d like to build membership levels back up again, ideally to pre-sabbatical levels. Once again, you can check out your membership options here if you’d like to help me reach that goal.

  1. Fun fact: right now, there are more former members of kottke.org than there are current members. Would like to change that!

  2. I read every single email and responded to as many as I could. My apologies if I didn’t reply to yours…there were just too many!

  1. Just as a sidebar, this creates an interesting cashflow situation — I get like 60% of my total revenue for the whole year delivered to my bank account in a space of 2 weeks. But I obviously have expenses and estimated tax payments that occur throughout the year, so I need to budget and manage that carefully. I’ve gotten used to it, but it’s taken awhile to acclimate.

I loved Everything Everywhere All at Once so much when I saw it in the theater last spring. It caught me in a low moment and swept me up in a protective embrace; it was magic. I was afraid this joyously weird movie would get lost in the Very Serious Film shuffle come awards time but I was beyond thrilled when I woke up this morning to the news that EEAAO swept the major categories for which it was nominated at the Oscars. Here are all the film’s wins from last night:

So happy for Michelle Yeoh and Ke Huy Quan in particular! Here are their acceptance speeches:

I am disappointed, but only slightly, that Stephanie Hsu didn’t win Best Supporting Actress — her audition for the role of Joy/Jobu Tupaki is amazing if you haven’t seen it. (And she also sang with David Byrne (who wore hot dog fingers) last night?)

Zeynep Tufekci: Here’s Why the Science Is Clear That Masks Work

Zeynep Tufekci: Here’s Why the Science Is Clear That Masks Work

09:53 Add Comment

You may have seen the online kerfuffle a few weeks ago about a study that was released recently that indicated that there was no evidence that masks work against respiratory illnesses (see Bret Stephen’s awful ideologically driven piece in the NY Times for instance). As many experts said at the time, that’s not what the review of the studies actually meant and the organization responsible recently apologized and clarified the review’s assertions.

In a typically well-argued and well-researched piece for the NY Times, Zeynep Tufekci explains what the review actually shows and why the science is clear that masks do work.

Scientists routinely use other kinds of data besides randomized reviews, including lab studies, natural experiments, real-life data and observational studies. All these should be taken into account to evaluate masks.

Lab studies, many of which were done during the pandemic, show that masks, particularly N95 respirators, can block viral particles. Linsey Marr, an aerosol scientist who has long studied airborne viral transmission, told me even cloth masks that fit well and use appropriate materials can help.

Real-life data can be complicated by variables that aren’t controlled for, but it’s worth examining even if studying it isn’t conclusive.

Japan, which emphasized wearing masks and mitigating airborne transmission, had a remarkably low death rate in 2020 even though it did not have any shutdowns and rarely tested and traced widely outside of clusters.

David Lazer, a political scientist at Northeastern University, calculated that before vaccines were available, U.S. states without mask mandates had 30 percent higher Covid death rates than those with mandates.

Randomized trials are difficult to do with masks and are not the only way to scientifically prove something. I’m hoping for an update that the entire premise of that Stephens piece is incorrect and will be removed from the Times’ website, but I don’t think it’s going to happen.
