Chemistry doesn't support your hypothesis. Sucrose rapidly decomposes into glucose and fructose via acid-catalysis. Coke is very acidic. The half-life of sucrose in coke under good storage conditions is ~2 weeks[0]. Modestly higher tem

The US also commonly has per-unit prices on the shelf tags. I think that practice started in the 1970s after some studies suggested it was beneficial.

Many of those old recipes on the notecards relied on heavily processed, shelf-stable industrial ingredients from a century ago that few people would use today. The recipes were commonly disseminated by companies as a form of marketing for t

You would be correct. US BLS survey data consistently indicates that a majority of Americans cook at home and almost never eat out. Affluent urban professionals, of which there are many on HN, may have their perception of the world influenc

Corn syrup is fructose-free. What do you want them to put on the label? People avoid HFCS for the fructose in it. Corn syrup is glucose. Corn syrup is one of the only plant-derived industrial-scale sweeteners that isn't substantially f

Making food from scratch is cheap. It also doesn't take much time unless you want it to. Choosing not to cook has become performative learned helplessness. I was far more likely to cook from scratch when I was poor than when I was not.

C++ succeeded twice. Initially, it provided a thin object-oriented abstraction over C. This solved many problems scaling large C projects. It set baseline expectations for languages that came later. Being a "thin object-oriented abstra

This particular population is highly selected because of the work they do and the types of clearances they hold. I would expect the suicide rate to differ significantly from the general population.

Autonomous and semi-autonomous systems address that.

It isn't just aging. Americans are spending a lot more on quality-of-life medical interventions, many of which are outside the normal standard of care that would be covered by healthcare systems. It is a booming business in the US and

Most likely minimal? The mass is low. I am, however, reminded that the orbit of the asteroid Juno (~250km diameter) permanently changed in 1839 without an obvious cause.

I think it is a mistake to optimize for happiness instead of life satisfaction. The latter is more durable and manifests as more productive social outcomes, since it is strongly correlated with self-actualization. There is no upper bound on

by jandrewrogers 2mo ago
I would much rather optimize for life satisfaction than happiness. If happiness is only weakly correlated with economics then it is poor policy to use economics as a lever to increase happiness. Life satisfaction, on the other hand, is co

One of the unique properties of gallium is that it does not form meaningful concentrated ores. The concentration of gallium in your backyard is roughly the same concentration as gallium literally everywhere. Consequently, every country has

There are several interesting foundational problems around scalability, generality, efficiency, and adaptability. Historically use cases haven't always been there to justify focusing on these problems but that is changing. In my opinio

The databases we use today in production have severe limitations and are not even close to what is theoretically possible. Many traditional parts of a database (indexing, caching, scheduling, et al) are AI-complete algorithm problems. Entir

Many database companies have research labs. It allows you to explore ideas, unorthodox concepts, and parts of the design space that may never be reflected in an actual product. Or to figure out how to solve specific hard problems that you c

The percentage of China's GDP that is dependent on foreign demand (15.7%) is the second lowest among major economies. The only major economy that is lower is the US at 9.0%, which is an extremely outlier.[0] By many OECD economic metri

The median US household is statistically within the ballpark of being able to achieve this per the data. Americans have extremely high incomes and anomalously low taxes on the middle-class. They can easily afford it. Whether they save or no

The anti-correlation between bonds and equities hasn’t been a thing for decades. That is advice that passed its sell-by date a while ago. The modern version is to go hard into equities and out-grow the drawdown risks. You still want a coupl

The downside is frontier computer science in several domains is decades beyond the state-of-the-art from academic literature. This is the situation that patents were designed to disincentivize. There is not an obvious path to making this re

by jandrewrogers 3mo ago
The patents are effectively unenforcible. People stopped patenting frontier computer science research 20 years ago. That is the current reality.

There is almost no benefit in publishing frontier research as a startup. People can try to argue it but it is not defensible. Publishing that kind of thing is a flex that companies risking nothing can do. Cool for Google. Problematic if you

Several things can be true simultaneously: The process and standards of peer-reviewed publication are tedious. If the objective is efficient communication of knowledge, this is not the process that maximizes that outcome. This process is ab
