ryandamm··on Ask HN: How are you acquiring your first hundred users?
Agreed, I'm torn between my pedantry for adhering to style guides and being pilloried for seeming like an AI. There's no safe ground anymore.

(Though I used to use the em dash with spaces on either side — like this — and only recently converted to the more common, tighter spacing—like this. I might go back to my old ways since it's different from how AI uses them, like some sort of weird shibboleth.)

All these comments are acting like this is a major problem with VCs in general.

Is this not a major problem with YC, specifically? Our beloved orange site funded and accelerated these guys.

Cooling in space was covered by XKCD's Randall Munroe in pretty entertaining detail here:

TL;DR... cooling in space isn't passive, you're on the "inside" of an enormous vacuum flask. And radiative coupling with space is possible from the ground, if that's what you're interested in:

But god bless crazy entrepreneurs. Don't ask whether we can, definitely don't ask if we should, just ask whether it makes for good headlines...

You think that would be sufficient? Did you read the article?

I did, and I have previously read an article in (iirc) The Atlantic about the screwfly program when it was working. It was a monumental effort to push screwflies back to the Darien Gap, involving widespread coordination of cattle ranchers and government workers, constant flyovers of planes dropping huge numbers of sterile flies, and a massive breeding program.

Two university students in a van can get about as much done as it sounds like. Some problems require coordination, government involvement, and yes, the organization — i.e., bureaucracy — that implies.

(Edit: it was The Atlantic, not The New Yorker. Comment further down has the link, but here it is: https://www.theatlantic.com/science/archive/2020/05/flesh-ea...)

Valid concern, but it seems like the glide path—continued carbon dioxide buildup and climate change—might eventually be worse than the unknown unknowns. (I suppose how one makes that decision is the challenge, hence the need for further study, per the article.)

This is one of the few carbon capture approaches that appears to be able to approach global scale, so I'm rooting for it. Even enhanced weathering suffers from needing to move billions of tons of rock, but scattering trace minerals seems pretty high leverage. The sheer mass of material that must be removed from the atmosphere is otherwise very intimidating.

ryandamm··on The Whimsical Investor
Curious if anyone else reading this knows about the equivalent of US "pink sheets," publicly traded companies that have either never been listed or have been delisted due to low share price / market capitalization.

Here in the US, you can buy publicly traded companies in the US for a song; in fact, that was the source for the "acquiring" company in a lot of those reverse-acquisitions of the late 2000s / early 2010s: publicly traded companies that had a ticker, but were basically defunct. A company that wanted to go public without the scrutiny of an IPO process could "buy themselves" with the tiny, publicly traded company, thereby getting a ticker and access to retail investors. (This was not a good phenomenon, fwiw, though it definitely anticipated the SPAC craze... which was also not good, for similar reasons.)

This may not be a particularly popular opinion, but current copyright laws in the US are pretty clearly in favor of training an AI as a transformative act, and covered by fair use. (I did confirm this belief in conversation with an IP attorney earlier this week, by the way, though I myself am not a lawyer.)

The best-positioned lawsuits to win, like NYTimes vs. OpenAI/MS, is actually based on violating terms of use, rather than infringing at training time.

Emitting works that violate copyright is certainly possible, but you could argue that the additional entropy required to pass into the model (the text prompt, or the random seed in a diffusion model) is necessary for the infringement. Regardless, the current law would suggest that the infringing action happens at inference time, not training.

I'm not making a claim that the copyright should work that way, merely that it does today.

ryandamm··on Deregulation in Argentina: Milei Takes "Deep Chainsaw" to Bureaucracy
Would love to hear more from Argentinians! Thank you for your perspective.
ryandamm··on Deregulation in Argentina: Milei Takes "Deep Chainsaw" to Bureaucracy
It has been significantly higher in the recent past.

For fun, look up how Brazil tamed inflation by creating a fake currency it never actually issued. (Taking off so no time to look it up myself.)

ryandamm··on Deregulation in Argentina: Milei Takes "Deep Chainsaw" to Bureaucracy
The money quote to me (as an American):

“Milei has implemented these reforms legally and constitutionally...”

ryandamm··on Deregulation in Argentina: Milei Takes "Deep Chainsaw" to Bureaucracy
As of right now, the comments on the Marginal Revolution blog are rather telling. Generally agreeing that the two situations are not remotely the same.
ryandamm··on Deregulation in Argentina: Milei Takes "Deep Chainsaw" to Bureaucracy
Or to put it another way: extreme steps were probably required in Argentina to tackle a truly hidebound, rentier-dominated and corruption riddled government. Inflation expectations were strong and justified. Government deficits were out of control. And the population was truly ready to bear some pain for the sake of reform. (Source: My guide in Argentina this past November; Milei’s approval rating has stayed high despite economic contraction.)

Argentina is what Trump’s team imagines the US to be. They’re not the same.

EDIT: fixed some typos.

ryandamm··on Deregulation in Argentina: Milei Takes "Deep Chainsaw" to Bureaucracy
Before anyone starts comparing to the US’s DOGE, let it be said that the two countries have virtually nothing in common economically.

Argentina has a nearly century-long history of economic volatility alternated with stagnation, massive inflation crises, a spell of military dictatorship (after a flirtation with fascism)…

Wait a second…

(In all seriousness, Argentina is truly unique. As economists say, there are only four kinds of economies in the world: developed, developing, Japan, and Argentina.)

ryandamm··on Canon EF and RF Lenses – All Autofocus Motors
Yup… but it’s not necessarily in the same state if you do it twice. It’s close, but not identical. Even if the image metadata claims the focus point is identical, the lens in all likelihood is not in the same state and will have some deviation in its intrinsics.
ryandamm··on Canon EF and RF Lenses – All Autofocus Motors
It’s open loop in that the measurement of it being in focus is reliant on the subject matter, and a different measurement.

I’m not making this up, camera manufacturers have told me to my face that focus is open loop, period. They can’t guarantee repeatable focus.

Notably the measurement isn’t of the state of the motor/gearing. Furthermore, being “in focus” means the subject matter’s out of focus blur is below some threshold; there is a range of focus states that qualifies — but those seemingly small differences can affect camera calibration, with >pixel-level differences in effective focal lengths.

It’s open loop.

ryandamm··on Canon EF and RF Lenses – All Autofocus Motors
A note of possible interest for this crowd: all these motor types are open loop, so you can't actually command a specific state with any accuracy / repeatability. In other words, if you send a signal to the lens to focus at, say, 3m, it won't necessarily be in exactly the same state as the next time you focus at 3m.

This is why camera calibration can be tricky, and you often don't want to touch the cameras after you've done a calibration pass.

I took Krugman's advice to read DeLong at one point and don't regret it, though he's not on my regular rotation:

I think you’re confusing correlation for causation.

I trust a Nobel Prize winner has thought through it more deeply and integrated the causes and effects more than most random internet commentators. I am happy to report that “low interest rates” do not cause inflation by themselves on any scale less than a decade. Source: 1995-2021.

What actually causes inflation is more a function of overall demand and supply in an economy. Interest rates have an indirect effect on that balance that can also have higher or lower leverage depending on a lot of other factors.

ryandamm··on The Demoralization is just Beginning
Krugman discussing the Internet might be like geohot discussing economics.

Or are you referring to the fact that he said it didn’t show up as having caused growth in the underlying economic data? I think he was pointing out something quantitative at the time, and in recent years he speculated that the strong growth in US GDP was finally reflecting efficiency and productivity gains from IT and the Internet. (The US’s strong growth until very very recently was an outgrowth of strong and rare increases in worker productivity.)

ryandamm··on The Demoralization is just Beginning
You’re describing Modern Monetary Theory (MMT), or really the parody of it that was popular in discussions online.

Krugman actually generally felt it went too far, and was not a proponent of it.

There is some similarity to his making fun of people worried about “bond vigilantes,” iirc. But I don’t think your characterization of his positions is accurate.

ryandamm··on The Demoralization is just Beginning
That was in response to the artificial debt ceiling. The coin was to be “deposited” and used a justification for why there didn’t need to be a vote to lift the debt ceiling for funds Congress has already allocated.

Conflating that with Keynesian principles is false. He didn’t propose that the trillion dollar coin would ever affect actual spending.

ryandamm··on The Demoralization is just Beginning
I think this comment is a little bit reductive and conspiratorial, even if it gets first-order correlations correct.

You don’t need a conspiracy, you just need a philosophy of small government and low regulation to let grifts expand through the financial parts of the economy. The history of financial regulation in the US is the banking industry finding new ways to evade regulation, which lead to moral hazards and privatized gains / socialized losses.

But it’s not that the “system” is explicitly designed that way; instead, it’s an adversarial system and the US in particular (for cultural reasons) has long favored the vigilante over the regulator.

The story works even without simple Hollywood villains. The system isn’t malicious, it’s just stupid.

Which is a long way of mostly agreeing with you.

(Oh, except on printing money. That’s a surprisingly deep subject that’s often misunderstood. You’re spot on about government-sponsored wealth redistribution, though. Fully on board with that.)

ryandamm··on The Demoralization is just Beginning
Yeah, there's a known problem with smart, technical people approaching fields about which they know very little. The analysis, to a third party, often sounds smart (the author is undeniably smart!), but without having expert context, you miss why it's so, so, so wrong.

And I'm not even an economics expert. I've just read more about it, or read more critically, than geohot. And I can tell you he's wrong, not because he's an outsider but because his analysis does not make sense.

Copernicus had well-reasoned, self-consistent arguments that incorporated previous models, and produced better results. This doesn't. There is a rubric for how one should score outsider contributions, even if you want to allow for revolutions in a particular field. This essay doesn't rise to that level.

In fact, it matches the first pattern -- smart person outside their field, makes ass of self -- much better.

A more succinct point: the US economy looked really strong in mid-2008. Consumption was very strong, but it turns out that consumption was fueled by unsustainable debt.

China has a serious debt problem in its economy. Not government debt like in the US, but shadow banking debt. My fear, based on reading Pettis primarily, is that the Chinese people will end up paying for that debt. Households that have expensive second homes as investment vehicles will suffer those losses (since there isn't sufficient population to fill those homes), unless those losses are socialized or redistributed.

ryandamm··on The Demoralization is just Beginning
https://carnegieendowment.org/china-financial-markets/2023/0...

I like Michael Pettis's analysis, though I'll grant you that the distortions he cites in the Chinese economy have gone on longer than he predicted possible. But the health of the Chinese economy is not just the visible things you cite, but also the distribution of assets and balance sheets in the economy.

Per Pettis (and other sources), the banking system is dealing with a large debt overhang in society. Pettis's proposed policy fix is to assign that debt to the state, to state-owned-enterprises, or to the corporate sector. Because the long-term growth of China's economy depends on being less reliant on exports, and having a more "normal" mix of domestic demand. There are nuances there, but Pettis does a better job than I do in explaining it.

The trouble is that it's not politically expedient to assign the losses due to (unrealized) bad debt to those entities. And the result is a slow, grinding failure in the housing sector. The government does have a tight lid on dissent, but I understand that the Chinese people are in a more precarious position than they should be due to many households having overinvested in nonproductive real estate projects. How that unwinds will be fascinating to watch, and extremely relevant to world economics and geopolitics.

To be clear, I really am hoping for the best for China and its people. The right policy is sometimes well-known but hard to execute, and that's the tragedy. (It's playing out now, in spectacular style, in the US.)

I don't think economics itself has gone wrong -- I think the US economy in particular has done a poor job of distributing the wealth it has created.

Ironically, that has created a populist backlash that has vaulted even worse economic ideas into power.

Anyone read "Capitalism in the 21st Century"? It's long and dense, but it does make some excellent, well-supported points about the structure of an economy that explains the current situation very well with historical antecedents.

This won't do it justice, but: inequality always increases, by definition, if the returns on capital outstrip the overall growth in the economy. (Think through that if it's not obvious; it's literally a mathematical truth.) The book argues that history is a series of long, slow accretions of wealth, with increasing inequality, until some shock (usually a violent revolution) overthrows the old system, resets inequality, and the cycle starts again. The latter half of the 20th century, for the US, was one notable exception: growth outstripped returns to capital, so the benefits of that growth were widely shared: inequality decreased. That trend ended in the ~1980s, and the widening inequality gap has fueled unrest.

And the book points out that we've seen this show before. I think we're in the "history repeating itself as farce" phase, though.

I do think there's some mutually-assured destruction here. If trade truly ends, I suspect it might end in a hot war, and no one knows how that would go. (Though to support some of the comments here, and the implied point of the original essay -- China's manufacturing base becomes much more strategically important in a hot war scenario.)

I mean, we've sort of long assumed that increasing trade ties led to peace, and the detente between the US and China was long taken as proof of that axiom. But morons with half-formed ideas about trade policy can blow up detente in less than 100 days, as it turns out.

The endpoint of this argument is pure self-reliance, for strategic reasons. And that endpoint is North Korea.
