  1. The Danish Defense Ministry also plans to fund two more dogsled teams to protect the 375,000-square-mile Northeast Greenland National Park, the largest in the world. These would be the hardcore Sirius patrols, viewed by the Danes as the Navy SEALs of the Arctic, which began operations during World War II.

    Two. Not one.

  2. a. Starting the app

    b. Enhancements

    c. More enhancements

    d. Deploy to iPhone

    e. The actual App

  3. TL;DR: homeschooling makes it much easier to individualize education, which makes it more efficient and meaningful.

  4. This is called the sponge city effect in my little world of demographics. In a declining region we often see the biggest city soaking up population since jobs and health services etc cluster in a single area rather than spreading out. Japan has been shrinking for three decades while Tokyo happily grows.

  5. people are rightfully upset about this atlantic story because it gets at a truly alarming issue: being added to large, ongoing group texts without consent

  1. Two weeks after his birth, Jeffrey’s health took a turn for the worse: He developed a heart defect common in premature infants – patent ductus arteriosus, or PDA. Jeffrey was scheduled for open-heart surgery and transferred to the nearest children’s hospital.

    In those days, surgery for PDA was invasive. Holes were cut on either side of Jeffrey’s tiny neck and chest to insert a catheter into his jugular vein. His little body was opened from breastbone to backbone, his flesh lifted aside, ribs pried apart, and a blood vessel near his heart tied off, and then all the tissues were stitched back together.

    Baby Jeffrey felt everything – every incision, every internal repair, every stitch. The medical team had not given their fragile patient any drugs, any comfort, anything to protect him from the excruciating pain of open-heart surgery – just a paralyzing agent to keep him still during the procedure.

    Five weeks later, Jeffrey passed away.

    In the days before her child’s death, Jill Lawson learned a shocking fact: Anesthetizing babies for surgery was not common practice. After Jeffrey died, Lawson called his doctor for reassurance. Surely, she thought, her child had been given something for the pain.

    “The anesthesiologist informed me that she had not used any anesthesia or analgesia on Jeffrey,” Lawson wrote in an account of her son’s experience. The doctor told the grieving mother it hadn’t even occurred to her to do so because it had never been demonstrated that babies can feel pain.

  2. The paradox of India:

    Punjab is over 60% vegetarian, but Tandoori chicken and butter chicken are its most popular dishes outside the state.

    Tamil Nadu is less than 1% vegetarian, but its "pure veg" idly, dosa, sambhar, pongal, etc are its most popular dishes outside the state.

  3. The Seneca is my middle finger to the aesthetic homogeneity and economic over-optimization of 21st century life.

    A keyboard for the low, low price of $3,600. Yes, a computer keyboard. Yes, US$. Although to be fair, it is not $3,600. Its "from $3,600".

  4. I have very wide error bars on the potential future of large language models, and I think you should too.

    Specifically, I wouldn't be surprised if, in three to five years, language models are capable of performing most (all?) cognitive economically-useful tasks beyond the level of human experts.

    And I also wouldn't be surprised if, in five years, the best models we have are better than the ones we have today, but only in “normal” ways where costs continue to decrease considerably and capabilities continue to get better but there's no fundamental paradigm shift that upends the world order.

  5. Since 1972, the General Social Survey has periodically asked whether people are happy with Yes, Maybe or No type answers. Here I use a net “happiness” measure, which is percentage Yes less percentage No with Maybe treated as zero.

    Average happiness is around +20 on this scale for all respondents from 1972 to the last pre-pandemic survey (2018). However, there is a wide gap of around 30 points between married and unmarried respondents.

    This “marital premium” is this paper’s subject. I describe how this premium varies across and within population groups. These include standard socio demographics (age, sex, race education, income) and more. I find little variety and thereby surface a notable regularity in US socio demography: there is a substantial marital premium for every group and subgroup I analyze, and this premium is usually close to the overall 30-point average.

    This holds not just for standard characteristics but also for those directly related to marriage like children and sex (and sex preference). I also find a “cohabitation premium”, but it is much smaller (10 points) than the marital premium. The analysis is mainly visual, and there is inevitably some interesting variety across seventeen figures, such as a 5-point increase in recent years.

  1. An Australian man with heart failure has become the first person in the world to walk out of a hospital with a total artificial heart implant.

    The Australian researchers and doctors behind the operation announced on Wednesday that the implant had been an “unmitigated clinical success” after the man lived with the device for more than 100 days before receiving a donor heart transplant in early March.

    The BiVACOR total artificial heart, invented by Queensland-born Dr Daniel Timms, is the world’s first implantable rotary blood pump that can act as a complete replacement for a human heart, using magnetic levitation technology to replicate the natural blood flow of a healthy heart.

  2. In the time California has spent failing to complete its 500-mile high-speed rail system, China has built more than 23,000 miles of high-speed rail. China does not spend years debating with judges over whether it needs to move a storage facility. That power leads to abuse and imperiousness. It also leads to trains.

    I do not want America to become China. But I do want it to be able to build trains.

  3. “People might think a glass of milk is innocuous,” she said. “It’s not. It’s full of violence.”

  4. On BizBuySell, the popular listings site where the Rizzos found the Smiths, “corporate refugees” ditching the 9-to-5 have surged to 42 percent of buyers, roughly double the 2021 figure. Meanwhile, nearly a quarter of American small businesses are owned by people 65 and older, making the Smiths part of a “silver tsunami” of sellers.

  1. James Harrison: The Man Who Saved 2.4 Million Babies: Hall of Fame.
  2. Coincidentally, this week both Tyler Cowen and Karthik S shared memories of playing card games as kids. And then today my sister mentioned my younger newphew had started playing Dungeons and Dragons recently. We have played card games and board games with our boys, especially during COVID and it was fun. Clearly we should do more of this.
  3. Another entry to the hall of fame. A different hall, sure, but come one, clearly this guy is a legend.
  4. A different way of learning math? Via Zvi, who belongs in a third hall. Can't fault him for lacking ambition but perhaps this is the rare tweet that should have been an article.
  5. A Cheeto Shaped Like the Pokemon Charizard Sells for Nearly $90,000. NYT Paywall but do you really need to read anything else?

  1. What struck me was this bit in the report:

    In a 2012 interview with Complex magazine, she recalled a scene in the 2006 film “Beautiful Ohio,” starring William Hurt and Rita Wilson, that featured her “naked tush.” It was, she said, “probably one of the most horrendous moments of my life.”

    “It would take an army — or Martin Scorsese — to ever get me naked again,” she added.

Characters vs. Actors

As a viewer, I almost never think about the person behind the character. Sure if a Christian Bale loses nearly 30kg for a role, its visible enough and stark enough that one is forced to think about the how of it. But for the most part, I watch the program and move on. Maybe if there is something really interesting or shocking, a comment to my SO.

So it is a jarring to see that the impact of a brief scene stuck with the actor for years after the fact.

These days there is enough nudity on screen that most of us are desensitized to seeing it and I hope the actors are too, to performing them. Even in 2006 or 2012, when maybe it was less common, I would not have imagined an actor, and especially an American1 actor, would be so traumatized by such a scene.

Maybe it is because she grew up in a time when that was a much bigger deal that it was harder on her. Perhaps actors like her were the trailblazers and paid a price and it is easier for actors now.

It is, however, possible to imagine a possibility where being naked on screen is traumatizing, no matter how common and acceptable. According to Claude, the "being naked in public" dream genre is common across cultures and age groups and more common in adoloscents.

If that is the case I shudder to imagine the cost of all the content on Netflix and other services in a few years time.

The report also has a bit on another scene she was not happy about. And guess what? At the time (and thankfully no longer), the report carried a photo from that scene.

  1. Though, it turns out, America has a complex relationship with nudity and sexuality. Who'da thunk! ↩

A few thoughts on LLMs

I need to sit down and combine some of these thoughts into a coherent piece but for now, I just want to dump it all here for reference later. I doubt any of these are original and I have certainly seen some elsewhere.

  1. Market structure for LLM makers may end up being like the airline market. High fixed cost to set up, hard to create a product differentiation that users care about (other than price), lots of competitors entering, at least in part due to the "prestige" of owning one. Lots of utility for consumers but hardly any profit for producers.

  2. An LLM with an infinite context window, one that can contain all my life, will be an entirely different product than an LLM with a limited context window. You can never have enough when it comes to context windows.

  3. Notwithstanding 1, "personality" makes a huge difference in the experience of working with an LLM and the ability to create the right one could determine whether a model can dominate a market or a niche. Claude Sonnet 3.5 absolutely had than special sauce in my experience. We need a lot more of it.

  4. I don’t see how we’re going to avoid a situation where the internet become lousy with AI-created, pseudo academic writing filled with made up facts and quotes, which will then get cemented into “knowledge” as those articles become the training fodder for future models.

    But combine it with the fact that if we all start getting our answers from LLMs, the online content & ad based business model goes caput and then what is the incentive for people to put up good content on the web? None.

  5. But anyone who has good proprietary, verified, high-quality data & content will potentially control the value for the customer even as base LLMs become a commodity. Therefore does more data and content start going behind the paywall? If it doesn't it becomes training data and cannot be monetized.

  1. For the best travel experiences you need either a lot of money, or a lot of time. Of the two modes, it is far better to have more time than money. Although it tries, money cannot buy what time delivers. You have enough time to attend the rare festival, to learn some new words, to understand what the real prices are, to wait out the weather, or to get to that place that takes a week in a jeep. Time is the one resource you can give yourself, so take advantage of this if you are young without money.

  2. ...we now have evidence that in real-world use it can do something that has never been seen before: twice-yearly injections in thousands of female trial volunteers in high-risk areas (South Africa and Uganda) showed a one hundred per cent prevention rate of HIV infection.

  3. I don’t think a lot of people appreciate how much of their overall lifestyle and relative certainty is backstopped by a steady, boring stability of systems they don’t understand or even realize exist.

  4. Me using LLMs for fun little personal projects: wow this thing is such a genius why do we even need humans anymore.

    Me trying to deploy LLMs in messy real-world environments: why is this thing so unbelievably stupid and dumb.

    This fits with my experience. But also for doing "real" work, prompt engineering matters. Giving the right instructions in the right order does make a difference.

    See more scepticism in this thread. Along with some of the comments I am hearing Satya Nadella made in his podcast with Dwarkesh, I wonder if we are seeing a vibe shift on AI?

  5. I have been building so many small products using LLMs. It has been fun, and useful. However, there are pitfalls that can waste so much time. A while back a friend asked me how I was using LLMs to write software. I thought “oh boy. how much time do you have!” and thus this post.

Again, for real work, prompt engineering matters.

  1. I think Grok 3 came in right at expectations, so I don't think there is much to update in terms of consensus projections on AI: still accelerating development, speed is a moat, compute still matters, no obvious secret sauce to making a frontier model if you have talent & chips.

  2. Anyone in 2035 should be able to marshall the intellectual capacity equivalent to everyone in 2025; everyone should have access to unlimited genius to direct however they can imagine. There is a great deal of talent right now without the resources to fully express itself, and if we change that, the resulting creative output of the world will lead to tremendous benefits for us all.

  1. For my day to day queries, I simply ask Claude, like I would ask a colleague or a friend and it just works. But for professional work, correctly prompting the LLMs improves the quality of output significantly. I hope to find (and create) more such examples.

  2. That is true for most other hard things too. The hard thing in pharma is not finding the compound but getting the trials and approvals done. The hard thing in politics in not the manifesto but the consensus.

  3. This is me with my dad, Bill White. For decades, he has been an evangelical pastor. Before I was born, he wrote a letter to my future wife. He didn’t know what we both do now: that I’m gay. When I came out nearly 16 years later, it shook his faith and fractured his church. But it never separated us. I wanted to understand how. So I read his journals.

  4. One of the reasons making things is satisfying is that it's a concrete demonstration of the notion that you can have some amount of control over your environment and circumstances. Passive media consumption is the opposite of that.

  5. But again, this is a distraction from any real issue! Oh, you should value the life of your brother more than a stranger? You don’t say? I’m hearing this for the first time! Now let’s kill five million foreign children to fund one sixth of a broadband boondoggle.

    I am happy to “concede” that if you face a choice between saving a stranger and saving your brother, save your brother! Or your cousin, or your great-uncle, or your seven-times-great-grand-nephew-twice-removed. I’ll “concede” all of this, immediately, because it’s all fake; none of your relatives were ever in any danger. The only point of this whole style of philosophical discussion is so that you can sound wise as you say “Ah, but is not saving your brother more important than saving a complete stranger?” then sentence five million strangers to death for basically no benefit while your brother continues to be a successful real estate agent in Des Moines.

    When will I be able to write so well?

Most books should have been blog posts, most blog posts should have been tweets and most tweets should never have been written. - Unknown Tweeter

Another set of AI-heavy links. I can’t help myself right now.

  1. These arrangements might have suggested that the league featured professional-grade cricket that an online audience would find worth watching, but in fact, the players weren’t established cricketers or even skilled amateurs. They were locals that Davda had recruited with the promise of paying 400 rupees (about £3.50) per day — twice what people in the area make in daily wages working on farms and for local businesses.

    Respect.

  2. But for the general obligation imposed upon us all, as time-bound creatures in a world shot through with intimations of transcendence, a different Eliot line is apt: “For us, there is only the trying. The rest is not our business.”

    I didn’t know Eliot plagiarized The Gita. The book is called Believe: Why Everyone Should Be Religious. I hope to read this book.

  3. Agency:

    PG
    Paul Graham@paulg · Jan 30

    This may be the most inspiring sentence I've ever read. Which is interesting because it's not phrased in the way things meant to be inspiring usually are.

  4. How to prepare for an AI future: Coincidentally, I ran into a number of pieces on this topic last week. The first one from Tyler Cowen and the second from Nate Silver. Both have the same advice in the first place: use LLMs more than you do and for more things than you do.
