rfreytag··on US moves closer to underground testing of nuclear weapons without any explosions
Interesting plot. It would need to have multiple parallel plots where each nation with a nuclear arsenal thinks they are the only one that has lost their nuclear capability. Hijinks ensue as each tries to bluff the national actors.

Nuclear weapons are not very useful when you have good intelligence and a distributed ability to delivey vast amounts of precious-guided weapons.

rfreytag··on Iron fuel shows its mettle
I assume they are using renewable energy to reduce naturally-occurring iron oxide.

When the iron is burnt are they going to do with pure oxygen? Otherwise they'll get pollutants like nitrogen dioxide, possibly ozone. And the 0.5% not burnt will also become a pollutant unless carefully removed in some smokestack scrubber.

Or is this 'burning' to occur some kind of iron fuel cell? How would they liquidize the iron which is quite heavy?

Lastly, iron is heavy. Moving reduced iron could be expensive and dangerous.

Still, if sufficiently close to the renewable source this could provide much needed load leveling for intermittent sources.

rfreytag··on Mistakes to avoid to build a better 1-person business
If you target a niche in a large market then you are targeting a small market. Create serial MVPs targeting those niches until you find product-market fit.
rfreytag··on When it comes to war, always follow the money
Article alleges it is not external threats but corrupt political interests that drive ever higher US defense spending. But correlation is not causation and this link is unsupported, especially when no analysis of the un/reality of the external threat is offered. There is some low-hanging fruit here around Iraq so not bringing that in leads me to question the quality of this article. It is harder to make that case with the Cold War or the PRC vs its South China Sea neighbors so perhaps that is why this aspect of their argument was not pursued.

rfreytag··on Update to the .NET language strategy
I think F# is going to do well because it is driven by the community making it an open field despite being .NET. F# developers seem to have a higher than usual lower-bound.

Elmish.WPF, FParsec, so much there and still things to do...like better development tooling with VS Studio Pro.

If it were a sure thing it wouldn't be a challenge or quite as interesting.

rfreytag··on Jamie: AI assistant that creates meeting summaries
Most important in-person meetings are not meant to be leaked. How do you address the concern your service could be a source of leaks?
rfreytag··on The FactoBattery
Hydrogen burns invisibly to the human eye [1]. It must be approached with caution lest one get burned. I have heard of a case where leaks detection consists of wiping pipes with a straw broom and noting if it bursts into flame.

rfreytag··on Memento mori
The motivation is this interesting story... ' After a major military victory, the triumphant military generals were paraded through the streets to the roars of the masses. The ceremonial procession could span the course of a day with the military leader riding in a chariot drawn by four horses. There was not a more coveted honor. The general was idolized, viewed as divine by his troops and the public alike. But riding in the same chariot, standing just behind the worshipped general, was a slave. The slave’s sole responsibility for the entirety of the procession was to whisper in the general’s ear continuously, “Respice post te. Hominem te esse memento. Memento mori!”

“Look behind. Remember thou art mortal. Remember you must die!”

The slave served to remind the victor at the peak of glory, this god-like adoration would soon end, while the truth of his mortality remained. '

That story is given here in the section titled "Romans": https://dailystoic.com/history-of-memento-mori/

rfreytag··on How I make my rugs
The comments veered away from Tabitha Arnold's work which is quite good. Her post (OP) is full of examples from an artist with a distinct point of view and the ability to convey it clearly.
rfreytag··on Alien Truth
PBS SpaceTime notes the fine structure constant (~1/137) is dimensionless and ubiquitous in physics. As a result, transmitting that ratio would be a good and clear indication we are intelligent enough to have at least that much physics: https://www.youtube.com/watch?v=RCSSgxV9qNw&t=564s

This might be better than mathematical constructs which conceivably do not require technology, "just" thought to discover.

rfreytag··on The Government Debt Iceberg
Government accounting books debt immediately but cannot book the offsetting gains accruing from social services that historically result in lower future costs of policing and incarceration and higher revenues from citizens living productive lives longer.

CATO repeatedly gets this wrong.

Investment delivered to increase the productivity of those currently unlikely to be productive will result in significant GDP growth.

The problem lies in government subsidies to already productive businesses and demographic groups that produce relatively small marginal growth for their investment. The Trump tax cut is the latest example of such a misallocation of capital.

Acknowledging the realities of increases in lifespan and extended quality of life along with a strong public campaign against age discrimination would greatly increase the productivity of a significant sector of the population while incurring relatively little additional training costs. This would then justify raising the Social Security retirement age with consequential decreases in the cost of that entitlement program.

These changes to budget priorities become vital if we are to avoid significant additional borrowing in the new high-interest environment.

Of course, as time marches on boomers will leave the Medicare and Social Security system resulting in a significant reduction in costs. The possibility of a surplus in a little over a decade is conceivable.

rfreytag··on Is the United States Exceptional?
The author fails to consider the direction or rate of change the USA standing versus other nations. For most factors considered by the author the outlook is not good for the USA. Churchill did say the USA can be counted on to do the right thing after trying every other option; but nothing changes for the better if one's head is stuck in the sand.
rfreytag··on Can computers be mathematicians?
Search for 24:07, about 3/4 down where Strogatz poses the question: "do you imagine ... there will be a time when the descendants of Lean will be able to teach themselves math, rather than having human teachers creating libraries?"
