Facts matter. Evidence matters. We should not ignore evidence because it disagrees with our ideology. And we certainly should not attack someone for trying to bring in evidence to a discussion about something as important as raising our children.

The poster you are responding to didn't even suggest a course of action. He mearly provided evidence that the "obvious" course of action might not be so obviously correct. You are free to (as another poster did) question the relevence, interperatation, or quality of the evidence, or provide other evidence or arguments to disagree with what the poster was presenting. But you should not attack someone for trying to have an evidence based discussion.

Even if he turns out to be completely wrong, figuring out how he is wrong will likely be far more enlightening than simply asserting that he is wrong on moral grounds.

> we can absolutely make a case for "ripping families apart"

I don't see how that isn't a suggestion of a course of action -- one that that is a blatant misuse of a study (with small effects only measured over a small time period) toward ideological ends, i.e. supporting the seizure of children of disadvantaged parents.

Moreover, I refuse to have an evidence-based discussion about whether certain people deserve human rights. That shifts the Overton window to present such ideas as acceptable, when in a civilized society they should not be.

Here's one modern example: https://pagethink.com/v/project-detail/Wiss-Janney-Elstner-A...

It really means massiveness and stability, in order to have an acceptable margin of safety.

One aspect of the theory is the notion of a line of thrust: https://en.wikipedia.org/wiki/Line_of_thrust

Arch dams might be the only type of "contemporary" looking structure that is habitually made in this way out of unreinforced concrete.

Although Gaudi was interested in structural optimization (using catenary models), he is an outlier in terms of design. He didn't comprehensively consider seismic aspects, though apparently he didn't do too badly: https://blog.sagradafamilia.org/en/divulgation/seismic-activ...

Thanks! Those were some interesting reads.

For what it's worth, children from at-risk families achieve better education when the father ends up incarcerated. So we can absolutely make a case for "ripping families apart" and against supporting "families as they are".

> My findings suggest that on average, parents who are on the margin of incarceration are likely to reduce the amount of schooling their child attains if they instead remain in the household. This can be explained because the removal from the household of a violent parent or a negative role model can create a safer environment for a child (Johnson, 2008; Jaffee et al., 2003). Incarceration is also a mechanism that can limit the intergenerational transmission of violence, substance abuse, and crime to children. This result also relates to findings in other fields that conclude that See Kling (2006), Aizer and Doyle, 2013; Di Tella and Schargrodsky (2013), Mueller-Smith, 2015; and Bhuller et al., 2016, among others. For example, using data from Sweden, Hjalmarsson and Lindquist (2007) report significant father-son correlations in criminal activity that begin to appear between ages 7 and 12, and are 3 the positive effects of being raised by one’s parents depend on the quality of care they can provide (Jaffee et al., 2003).

I am appalled that such an assertion can be made openly. It is, frankly, simply vile to suggest that children be taken away from struggling parents by society, rather than society being obligated to help those parents raise their children. To do so would be not only criminal, but profoundly immoral.

Rebar makes earthquakes worse, as seen in California's freeway collapse. The rebar depends on the concrete to prevent corrosion, but that is only good for roughly 50 years. Rust causes expansion, which cases cracking. The outer concrete falls away, leaving rebar to get crushed under the load. The obvious fixes, like stainless steel rebar, have thermal expansion coefficients that don't match concrete, so instead you get cracking even without corrosion.

Lots of Roman stuff is still standing in areas that get earthquakes. The solution is to use a conservative design, with arches and thick walls. Domes are good. We can improve on this with 3D printing, using a structure like mammalian bone: solid near the surface, and spongy in the middle.

Would you be able to provide links to modern structures built with the methods you're describing or research about them? Does this conservative design resemble something like Gaudi's Sagrada Familia, or is that the wrong way to think about it?

Random tangent: As much as I love living in sunny California, it saddens me that due to earthquakes, nothing we build here will still be around in 2,000 years.

That's only because the construction isn't as sturdy. Italy routinely experiences earthquakes similar in magnitude to California.

> file patents in Jamaica to claim precedence on things that others may have thought of

Can you explain how this works? Why would anyone care about Jamaican patents if they apparently don't play properly?

wjnqx · 7 years ago
> "The tech giants are exploiting a US trademark-law provision that lets them effectively claim a trademark in secret."

Jamaica and some other countries don't maintain searchable databases, allowing companies to register trademarks abroad in secret and then point to those registrations when claiming the mark in the US.

I am well aware that most people on Hacker News hate Bitcoin and cryptocurrencies so a lot of these types of studies and articles that are negative end up making their way to the top.

It is strange that this study was from 2017-2018 and yet they only considered data from 2009-2013. Would be nice if there was an explanation as to why.

One thing I wanted to point out is this seems to be presented to shine a negative light on Bitcoin, but I have a feeling that if you were to plot the owners of any equity you would find the exact same patterns. People who get in early will own a majority of the supply.

For example take a look at Morgan Stanley stock. 86% of the shares are owned by institutional investors and of that chunk, five institutions own 58% of them:

https://www.nasdaq.com/symbol/ms/ownership-summary

I also think these types of patterns with regards to transactions probably exist with other currencies as well, but it is just that the data is not available for the public to analyze.

To be fair, stock in Morgan Stanley is not marketed as "decentralized."

Most poor advocacy groups keep pushing low income subsidized housing.

Which is a small band-aid that will never work. It creates lotteries where literally hundreds of people apply for a single home and one lucky person gets it. So one person is helped but the majority get nothing.

We need to actually fix the system, not create lotto winners.

wjnqx · 7 years ago
So why not just build social housing at a larger scale? It'd put actual downward force on the market by turning publicly-owned housing from a lottery into legitimate competition with privately-owned housing.

1. It's not a tax any more than buying a ticket for your local government run public transport system is a tax.

2. Why do people always jump to thinking road pricing will be extremely expensive? Outside of rush hours, it would probably still be free almost everywhere, and it should offset other road financing costs motorist - rich and poor - currently pay.

wjnqx · 7 years ago
I'm not sure it's been studied, but I'd wager that every tax dollar spent on subsidizing public transit (or possibly even making it free) would deliver several dollars of gain. Physical mobility is one of the best predictors of economic mobility[0], and I imagine the poor would be able to find better jobs with fewer economic hurdles put in front of them.
