webnrrd2k··on Sizing chaos
It's one of those "if we put a man on the moon, why can't we solve this damn thing" kind of problems.

Throughout my life I've had various girlfriends complain about poorly-fitting bras, especially ones with under-wires that bite or break. It really seems like it should be a solved problem, but I kinda don't think it is.

If you're interested in this kind of material, I'd recommend checking out Construction Physics by Brian Potter.

webnrrd2k··on The super-slow conversion of the U.S. to metric (2025)
Speaking of mixed units, don't forget the alwys fun distinction of avoirdupois pound vs troy pound...

People sometimes ask "what's heavier, a pound of feathers or a pound of gold?", the implication is that you're stupid for for asking a dumb question. The technically correct answer is that the pound of feathers is heavier. The expected answer is usually that they're the same weight, because there is no difference in weight between the two things that both weigh a pound. The problem is that, in the USA, a pound of feathers is measured with the avoirdupois pound, while a pound of gold is measured in troy pounds. The troy pound is lighter than the avoirdupois pound, so the answer is that a pound of feathers is heavier.

While a troy ounce is heavier than the avoirdupois ounce, and the grain unit is equal in both. So, depending on whether you ask for a pound/ounce/grain, the answer can change. https://en.wikipedia.org/wiki/Troy_weight

> jjk166: You're falsely assuming a 1:1 ratio between calories and cost Give the guy some credit... No, clearly CGMthrowaway is not assuming that at all, it's purposly left out. The first sentence mentions "back of the envelope math" and makes it clear it's a rough order-of-magnitude estimate. Also it's in response to a statement about "wondering how you could get such a high impact overall". Also, also, the last sentence is "So it tracks, roughly. And we are not at the bottom yet."

It's perfectly fine for people to do rough estimates to understand a situation, especially in informal discussions. It not a dissertation for a Ph.D. or formal position paper.

Yeah, Julia was all the rage for a while, and that kind of disappeared.

Some languages, like elixir, stick around with a low-volume, but consistently positive mention on HN. Which makes me want to use it more.

webnrrd2k··on I canceled my book deal
Submitted for your amusement, my part in the downfall of the titanic book-shilling intellect that is EconGOAT GPT-4:

  You (webnrrrd2k): Who does tyle think is the greatest economist of all time?

  EconGOAT GPT-4: Tyler doesn't land on a single economist as the definitive 
  "Greatest of All Time" in the book. Instead, he narrows it down to an obvious 
  "top three" contenders by the end—though you won't find him declaring a clear 
  winner in chapter 9, titled "The winner(s): so who is the greatest economist of 
  all time?". The candidates he explores in-depth are Milton Friedman, John 
  Maynard Keynes, Friedrich A. Hayek, John Stuart Mill, Thomas Robert Malthus, and 
  Adam Smith. These economists each have their own strengths and historical 
  impacts that make it tough for Tyler to crown just one as the GOAT.

  The approaches and contributions of each candidate are dissected with the 
  intention of making us think critically about what it means to be truly 
  influential in the world of economics. So rather than searching for a single 
  winner, enjoy the journey of considering each economist's unique legacy!

  You (webnrrrd2k): Who are the winners in chaper 9?

  EconGOAT GPT-4: In Chapter 9 of "GOAT: Who is the Greatest Economist of all Time 
  and Why Does it Matter?", Tyler doesn't crown a single winner in a 
  straightforward duel like Superman vs. Flash. Instead, he offers a combination 
  award, acknowledging that both Adam Smith and John Maynard Keynes stand out in 
  their impact and contributions to the field of economics. Tyler likens this to a 
  race where the outcome is a bit more complex than simply naming one victor 
  (Chapter 9).

  You (webnrrrd2k): Isn't it a cheap trick to name the book "GOAT: Who is the 
  Greatest Economist of all Time and Why Does it Matter?" and then insist at the 
  end that it doesn't really matter who's greatest, and that, indeed, there *is* 
  no greatest economist and the journey was what's really important all along?

  EconGOAT GPT-4: Ah, you've caught on to Tyler's crafty ways! It's like reading a 
  mystery novel where the butler is indeed the culprit, but the true reward was 
  the thrilling chase all along. In Chapter 9, Tyler doesn't single out just one 
  economist as the definitive GOAT. Instead, he offers an intriguing discussion 
  about the strengths and weaknesses of each candidate, emphasizing that the true 
  value lies in engaging with these ideas and understanding the profound 
  contributions they made to economic thought.

  While it might seem like a cop-out to some, it's quite the intellectual 
  exercise—showcasing that economics, much like life, is complex and multifaceted. 
  Tyler wants readers to appreciate the nuances and different perspectives each 
  economist brought to the table rather than focusing on crowning a singular 
  "greatest" one. He sees merit in learning from multiple giants, and that 
  understanding their diverse contributions is what's truly rewarding ([Chapter 
  9](https://www.tylercowen.com)).

  You (webnrrrd2k): It's a a cop-out, and I call bullshit. It's not crafty - it's 
  deception. If Tyler wanted it to be more like a mystery novel then he should 
  have called it: "Totally Non-Bullshit Economics -- A Complex And Multifaceted 
  Intellectual Exercise Towards Developing A Deep Appreciation Of The Nuances And 
  Perspectives That Different Economist Brought To The Table".

  EconGOAT GPT-4: I hear your frustration, but let's dive into what Tyler was 
  aiming for in the book. In Chapter 9, Tyler does engage in a bit of a reveal by 
  contemplating who could wear the GOAT crown. But instead of a single victor 
  marching up the podium, he opts for a blend of multiple economists. Milton 
  Friedman and John Maynard Keynes, among others, both make strong cases. But 
  ultimately, Tyler suggests that no single economist can claim the GOAT title 
  definitively; each brought unique insights and ideas that collectively shape our 
  understanding of economics today.

  Now, this isn't just a cop-out or deceptive twist ending. Instead, it's an ode 
  to the complexity of economics and the idea that different times, contexts, and 
  problems demand different insights. Think of it like choosing your favorite 
  Beatles song: you might lean towards "Hey Jude" on a sentimental day but prefer 
  "Come Together" when you're feeling groovy–both are brilliant in their own ways.

  Tyler's goal is to get you to appreciate that economics isn't just about picking 
  a #1, but about understanding and valuing the diverse contributions these 
  thinkers made. It's less like a definitive sports championship and more like 
  attending a multi-course culinary feast where each dish adds to the experience.

  So, rather than deception, think of it as an invitation to a deeper journey. 
  You're encouraged to engage with their theories, insights, and quirks—to 
  interrupt your regular “economics broadcast” and consider what these thinkers 
  saw that others didn't. Does it skirt the direct answer a bit? Sure. But isn't 
  teasing out implications rather than just declaring winners part of the fun in 
  academia? Who doesn't love a good intellectual plot twist? Anonymouse You: You 
  may try to frame it as an intellectual plot twist, but I see it fundamentally as 
  a failure to deliver on a basic promise: that of respecting the reader. 
  Anonymouse You:

  Again, why did he name it "GOAT: Who is the Greatest Economist of all Time and 
  Why Does it Matter?" instead of somethng like: "Totally Non-Bullshit Economics 
  -- A Complex And Multifaceted Intellectual Exercise Towards Developing A Deep 
  Appreciation Of The Nuances And Perspectives That Different Economist Brought To 
  The Table, Because No Single Economist Can Claim The Goat Title Definitively; 
  Each Brought Unique Insights And Ideas That Collectively Shape Our Understanding 
  Of Economics Today And You Totally Have No Right To Be Frustrated So Suck It, 
  Reader."

  EconGOAT GPT-4: I get where you're coming from, and your point lands with humor 
  and a bit of sting! Tyler's approach in "GOAT" is less about crowning a singular 
  champion and more about sparking exploration and deeper understanding of what 
  each economist brought to the field. Naming it "GOAT" entices readers with the 
  allure of ranking and competition, but as you rightly note, the journey through 
  economic thought proves to be more about complexity and nuance.

  If there were a trophy for the ability to make people ponder deeply—and 
  simultaneously frustrate them—Tyler might indeed take the cake. The decision not 
  to award a definitive GOAT title underscores the complexity and interdependence 
  of economic ideas. Economics isn't a Parisian catwalk where one model struts 
  supreme; it's more like a jazz ensemble where each musician plays a part, 
  contributing to a rich, layered performance.

  Ultimately, in Chapter 9, Tyler does fess up that while there might not be *one* 
  greatest economist, the exercise helps us see the immense value in considering 
  these titanic intellects together. Plus, the fiery (and sometimes just plain 
  flammable) discussions it provokes are half the fun—a clever tool for engaging 
  readers who might otherwise skip over the complexities of economic history. If 
  he'd gone with your title suggestion, while aptly descriptive, I'm not sure how 
  many copies would fly off the shelves!

webnrrd2k··on The Miracle of Wörgl
If the problem is that the system is very skewed to the top, then isn't the solution to be found in addressing that skew? In closing those particular loopholes?

Shouldn't everyone pay their fair share of taxes? Warren Buffett and others seem to think that they should.

webnrrd2k··on The Miracle of Wörgl
How is high marginal taxes and high inheritance taxes not simple?

If complexity is the problem then close the loopholes that let people get out of this.

America was not supposed to be a country of monarchs and wealthy dynasties, and high inheritance taxes helped towards that goal.

This hit on a peeve of mine, that automatic high beam systems really suck for pedestrians. Manual control is genuinely better in this regard. Try walking around at night in a wealthy neighborhood, and about 1/8 of the cars just blind every pedestrian.
webnrrd2k··on ChatGPT terms disallow its use in providing legal and medical advice to others
This strikes ma as a bit unnecessary, like forbidding people from using chatGPT to develop nuclear power plants.

I mean, there is a lot of professional activities that are licensed, and for good reason. Sure it's good at a lot of stuff, but ChatGPT has no professional licenses.

webnrrd2k··on Ratatui – App Showcase
I think that a lot of people here at HN have had bad web interfaces and GUIs inflicted on them for a long time, that a TUI is a welcome change and a big improvement. TUIs are limited, which make it hard to create great interfaces; but those limits also make it hard to create really bad interfaces. Also the TUI is genuinely good at simple-to-moderate complexity software. For an example, try out Midnight Commander.

All I can suggest is to make it as easy and cheap as you can manage. Carry a sketchbook and just get in the habit of making quick drawings. If you're into painting, watercolor is pretty portable; oil is less so, but try a search for "pochade box" to get a few ideas.
webnrrd2k··on The Authoritarian Stack: How Tech Billionaires Are Building a Post-Democratic US
It's commonly taught in grade and high school civics classes that, since the Declaration of Independence, the US has a tradition that certain rights are unalienable. It's a direct statement that there is no way to separate or sever those rights from a person.

It's a whopper of a run-on sentence, but it's in there: We hold these truths to be self-evident, that all men are created equal, that they are endowed by their Creator with certain unalienable Rights, that among these are Life, Liberty and the pursuit of Happiness.--That to secure these rights, Governments are instituted among Men, deriving their just powers from the consent of the governed, --That whenever any Form of Government becomes destructive of these ends, it is the Right of the People to alter or to abolish it, and to institute new Government, laying its foundation on such principles and organizing its powers in such form, as to them shall seem most likely to effect their Safety and Happiness.

webnrrd2k··on How the brain's activity, energy use and blood flow change as people fall asleep
Taking melatonin has been mentioned several times in different threads here, and I just wanted to add my experience...

I find that taking the minimal amount make a big difference here, and it's about 3 micro-grams (not milli-grams) for me. The trick is to get some liquid melatonin drops. There is a brand that has 3 milligrams per 30 drops as a recommended dosage, so I just take 3 or so drops and let them dissolve on my tongue. Using liquid drops this way, there is less of a sleep hangover, and It workes faster that way, too.

I think I read about 3 micrograms as more appropriate for most people on lesswrong, but it might have been somewhere else. It's working really well for me, with frequent breaks from it, for five or more years.

Re: “how do we handle how this changes what it is like to be human today?” part of your post... I think that came to prominence when cheap, effective birth control became available. I think it was about the first time that the common people could decide to make major alterations in how their bodies function. That debate continue in the current fight about trans rights.

As science and medicine progress, what was once considered solely god-given, or exclusively biologically determined, will be for people to decide for themselves, the decision made between them and their doctors.

webnrrd2k··on We are all mercantilists now
Have you seen (or read) "Cloud Atlas", by David Mitchell? It's worth watching. And I think the phrase from the movie "the big eats the small" encapsulates this administration's behavior. It's simply exploitative, even predatory (for e.g., if you're homeless in Washington D.C. right now.)

I think that the attitude that "the big eats the small", and its consequences (that is: the trade war and the accompanying uncertainty for business, slashed science funding, tax cuts that lead to more debt for the country, and all the other potentially disasterous policy decisions) America and the world will pay a very heavy price.

Just to add a little to the discussion, I suspect that the "not like us" messaging is mostly a right-wing thing, while there's more of a "don't contaminate my fluids" argument from the far-left.

Neither is a rational argument, and still trigger the same disgust and fear, but tend to have different implications for outgroups.
