petilon··on My husbands suicide shows theres something very wrong with US insurance industry
An itemized bill from the hospital for about four weeks of his hospital stay. It came to a little over $4 million. https://www.cbsnews.com/news/covid-19-deaths-families-60-min...

Numerous studies have found that when doctors have a financial stake in a hospital, they tend to order more tests and procedures, raising costs for Medicare and other insurers. https://www.nytimes.com/2011/12/13/health/policy/republican-...

petilon··on My husbands suicide shows theres something very wrong with US insurance industry
Yes, there is something wrong with the insurance industry. But there is something wrong with the hospitals, doctors and drug companies too. The whole system is broken. Hospitals try to eke out the most out of insurance companies, often providing services that are unnecessary. Pharmaceutical companies charge US patients significantly higher rates than in other countries. Don't put all the blame on insurance companies.

Chinese students still want to attend US universities [1]. While it is true that the progress made by China is a factor, this administration's policies are the bigger deterrent [2] [3].

"China can draw on a talent pool of 1.3 billion people, but the United States can draw on a talent pool of 7 billion and recombine them in a diverse culture that enhances creativity in a way that ethnic Han nationalism cannot." --Lee Kuan Yew, former prime minister of Singapore.

No it is H-1B visa. Right out of the university it is hard to recognize extraordinary talent. People like Sundar Pichai were not recognized as extraordinary right out of the university, he had to start at the bottom and rise up the ranks.

The current administration's immigration policy isn't helping. This wouldn't have happened 10 years ago because the US was this city on the hill that everyone wanted to immigrate to. Talented Asian researchers would have immigrated to the US and China would be deprived of talent.

Magnesium glycinate and magnesium taurate work for me. I mainly rely on the former.

I take it at night. Unfortunately I haven't found a controlled release version of magnesium that works.

I sometimes also take it during the day when I feel my muscles getting stiff, I get relief within 15 minutes.

petilon··on SpaceX stock erases all its gains and slides below IPO price in intraday trading
SpaceX, despite its name is an AI company, supposedly. Its S-1 states that the company estimates its total addressable market (TAM) at $28.5 trillion, of which $26.5 trillion, or 92.98%, is expected to come from AI.

SpaceX is an AI company without a frontier model. Until Jan 2026 SpaceX was an aerospace company. Then xAI was merged into SpaceX on January 30, 2026, so SpaceX became an AI company less than 6 months ago.

You could say that about electricity, water supply, healthcare, AI, etc. These should all be public services, not run by for-profit corporations. But we decided against that approach long ago.

You are absolutely right about that. It is important to reduce stress. Insomnia is only one of the ways excessive stress shows up.

Apple Card aka Goldman Sachs is notoriously bad at handling disputes. They were fined $89 million for mishandling disputes, yet they continue to reject disputes offhand [1]. I no longer use Apple Card other than for Apple Store purchases.

I find that Magnesium Glycinate works well for me. Magnesium Taurate also works.

Doctors do overlook simple natural solutions. This is because of how evidence-based medicine works.

The problem is not with evidence-based medicine itself, but with how the evidence is generated. The gold standard of medical evidence--a large, randomized, double-blind clinical trial--is extraordinarily expensive. In practice, much of this research is funded by private industry, which must have a reasonable expectation of earning a return on its investment. That naturally directs research toward treatments that can be patented, commercialized, and sold at a profit.

This creates a structural blind spot. Many naturally occurring compounds cannot be patented in their natural form, making it difficult to justify the enormous cost of conducting the kind of trials that modern medicine demands. As a result, potentially useful natural therapies often remain under-studied, not because they have been proven ineffective, but because the economic incentives to investigate them are weak.

This is the reason your doctor is much more likely prescribe Ambien CR than to suggest trying magnesium supplements.

Good point about L-threonate. It is indeed expensive. I use some of it, but mostly I rely on Magnesium Glycinate.

They only have blood tests, and that's not very useful.
petilon··on Sleep regularity is a stronger predictor of mortality risk than sleep duration (2023)
Blood tests are pretty useless for magnesium. The deficiency is in cells, magnesium level in blood is not a good test for that deficiency.

Magnesium supplementation solved my sleep issues.

I have seen many doctors, including sleep specialists, regarding insomnia. They all pointed to one source as the reason for the sleep issues: stress. And they all wanted to put me on prescription sleeping pills. I said no to that. Sleeping pills can cause dependence, and they often treat the symptom rather than the underlying cause. As a software developer, I am used to finding and fixing the underlying problem instead of relying on the quick fixes these doctors were offering me.

After much research, I figured out what I believe was the underlying problem, and the fix for it. The underlying problem was magnesium deficiency. As a software developer, I spend much of the day doing mentally demanding work. This is the kind of stress the doctors were talking about. Stress can increase the body's demand for magnesium and may contribute to low magnesium levels.

The cells in our body depend on minerals such as calcium and magnesium for normal function. In muscle and nerve cells, calcium helps switch the cell into an active state, while magnesium helps keep that activation under control and supports the return to a resting state. When you are low on magnesium, your muscles may remain tense and your nervous system may have a harder time settling down. That can contribute to muscle stiffness and difficulty sleeping.

The solution, in my case, was magnesium supplements. They fixed my muscle stiffness issues and my sleep issues. A special form of magnesium called magnesium L-threonate may be especially helpful for the brain because it appears to raise brain magnesium levels more effectively than some other forms.

petilon··on C++20 Improved the For-Loop Syntax
C++ is probably the only language that needs a strong style guide, to define a subset you are allowed to use in the project.

Linus Torwalds famously said that subset is zero. You're not allowed to use C++ in Linux, a wise move.

Here's Google's: https://google.github.io/styleguide/cppguide.html Search for "do not use" and you'll find plenty of hits.
