dluan··on California farmers are struggling to sell grapes as demand for wine drops
Reportedly, last year ~10% of California vineyards were uprooted, some grapes like Pinot Noir production is down 30%. Growers are going to keep trimming until they get back into the black, or prices fall down far enough for consumers to come back, whichever happens first. And it's not going to be just CA, it will be NY, TX, WA, OR wineries too, all areas that had big capex expansion over the past 10 years.

You can see it happening in real-time, right this moment. Go to your local Costco wine section, look for the clearance markdowns where the price ends in $0.97. That means it's marked for clearance and won't be coming back, and there's some screaming deals right now.

dluan··on California farmers are struggling to sell grapes as demand for wine drops
Because of years of trade war, American wine industry is taking a beating around the world and a lot of Australia, NZ, and South Africa is picking up that slack. Even niche producers like Chinese and Japanese wine industry are very quickly maturing into real home-grown industries. The biggest market for California has always been Asia, and it's been near impossible to stumble into Opus One the way you used to be able to in Tokyo, Hong Kong, Beijing, etc.

Old world has always been able to be flexible, eating these kinds of punches by pivoting into NA or brandy during gluts, and demand has less fluctuations. This contraction, like a lot of everything else happening in the US, maybe was already coming because of some trends overlapping, but policy threw gasoline onto a combustible and fragile situation.

I used to use search commands with "quotes", triple quotes, and +exact word search, I noticed last weekish that those no longer work.

Taiwan did not have anywhere near the land distribution occur under CKS/CCK, nor the same veracity of landlord clique ownership. And, you're further wrong in that a big part of white terror was specifically due to 外省人 owners of factories and farms, from land stolen from the aborigines. The white terror wasn't by any means less violent and senseless than cultural revolution.

My point is that a single land value tax would have the same effect as piecemeal improvements to current tax portfolio - none of it would fix the inertia already priced and baked into the system.

Famine along the yellow river and yangtze river has been happening for thousands of years across all dynasties, its specifically what land distribution was meant to fix, and since 1960s there hasn't been a famine since. My parents and grandparents lived through it and left cities to work in countryside fields during the cultural revolution. You tell me how the famine fits in and I'll let you know if you're accurate or not.

The greatest feat that Mao achieved was to take the land that had been tightly gripped by generations upon generations of owners and to shake up the distribution of it so that the land could produce again. People naturally want to work the land, but you end up with suboptimal inertia because owners just end up letting it sit fallow if it doesn't immediately return. It's how you turn a billion serfs into a billion entrepreneurs.

We're already way past the point where a creative cocktail of 10 different progressive taxation schemes could feasibly fix the root of the problem, and you feel this especially if you were born after the year 2000. You're more likely to see results if you pick up a red scarf than if you pass a higher wealth tax, sales tax, land tax, consumption tax, estate tax...

You can move your alipay card into apple wallet and have it as the default payment method, so do you don't even have to swipe or turn on your phone, it will even work in low-power/off mode.
dluan··on Suica, Japan's First IC Transit Card
I much prefer convenient over fast, being able to just tap my phone's uploaded IC card/alipay without having to open it up or switch cards is maybe 200ms slower, but I don't have to think or change what I'm doing. Plus with alipay it will just autodeduct so I don't ever have to think about that as well, though Apple wallet Suica makes it easy to reload too.

dluan··on Super El Niño Keeps Growing as New Forecasts Reach Record Territory Ahead Winter
I don't know enough about climate science, but south swell usually is the result of west-to-east storms coming off of Australia. In Hawaii, this summer's south swell has been extremely consistent big swells. I imagine it's something like the west coast off South America heating up causes the balance of the southern hemisphere off Africa to counteract that.

dluan··on Super El Niño Keeps Growing as New Forecasts Reach Record Territory Ahead Winter
China is the only country that is seriously doing anything about anything. They've single handedly built more renewable energy capacity than every other country combined, they've pulled millions of diesel and gasoline cars off roads, reforested one of the world's biggest deserts, this year they've finally reduced coal usage, and next year the long awaited Tokamak is set to fire for the first time.

The US is busy sending warships across the planet to blow up oil refineries which will be rebuilt. It's not bad enough we are busy grinding sand, but we are actively making things worse.

dluan··on Mushroom behind 'tiny people' hallucinations identified
These are pretty famous mushrooms in China. Right now Yunnan mushroom hot pot is all the rage, basically in every city in the country. It's also led to lots of tourists in Yunnan wandering around foraging for wild mushrooms. The problem is that there's hundreds of different types of mushrooms with varying levels of toxicity, and unless you grew up in the area and know what you're doing it's easy to get mixed up. There's plenty of videos on chinese social media of people giggling in hospital beds geeked out their gourds pointing at little people.

dluan··on NSF pilots 4-year PhDs with industry research placements
China actually started piloting the "industry Phd" in 2025, and took inspiration from Japan, Germany, and UK where some programs do industry experience as part of Phd training. A lot of the Chinese programs are in agriculture, engineering, and biotech. China's Ministry of Education actually published the "suggestion for experimentation" (loose translation) in 2023, and it trickled out from there as each province level government and university system started designing their own systems.

dluan··on Show HN: Physically accurate black hole you can put in your room
VR is fine when it's small cute bunnies or little golf balls that I can kind of immediately get a sense of scale for. Massive thing that tricks my brain like the edge of a gas giant is terrifying, no matter how much I tell myself it's just a screen or video or pixels.
dluan··on Show HN: Physically accurate black hole you can put in your room
I have no idea, on screen or even in movies it's totally fine, but I think just in VR where it's so immersive, and then being confronted with a thing that my brain doesn't really know how to understand the size of. Just like, hey there lil guy I know you're big and massive, wait where is your edge...
dluan··on Show HN: Physically accurate black hole you can put in your room
I remember like 10 years ago when Occulus first came out there was that space simulation demo where you could go around the solar system in VR. You could also "fast travel" by zooming in towards a planet, moon, blackhole.

Yeah, that was the day I learned I have a deep, crippling phobia of large objects. And Melanoheliophobia, which is fear of black holes. The only other time I've felt that way was snorkeling once near a giant 3 story tall bait ball of swirling fish, which was so disorienting and panic inducing that I vomited.

dluan··on U.S. science is in chaos
The arrogance and ignorance so voluntarily put up on display is mind numbing.

Not only have I worked as a science funder for the past 15 years as the founder of Experiment.com and with countless partner foundations and grant programs, having personally funded and peer reviewed thousands and thousands of projects, I've also sat as a member of countless NBER meta science panels alongside NIH and NSF directors where everyone's main pressure is earnestly trying to improve the efficiency and returns of science funding. Mainly to combat the false beliefs around science funding that people like you have spread.

The number one universal lesson of funding basic research, going back from Vannevar Bush to Carl Sagan to small risky out-of-bounds research, is that you don't pick and choose where impact comes from. You don't get to try and justify based on your political preference where you think the most progress will come from. That's not any of this works. The funding of a random jellyfish protein that eventually turns into the discovery of GFP only ten years later is not the kind of thing you can try and predict ahead of time or concoct on paper.

If you don't understand how basic research and impact works, then yeah you shouldn't be allowed to have hot takes about the system that millions of scientists rely on. You're dressing up anti-intellectualism behind a sham of commitment towards meritocracy when you won't even support the people who deserve it on merit. Get lost.

dluan··on U.S. science is in chaos
America is facing a multi-generational technical decline never before seen that will do irreparable harm across all fields of research, let alone the human cost especially borne by young scientists who have more to lose, and your grand insightful take is that well, some of it deserved to get cut, when you're not even the one making the decisions of which ones do receive funding.
