The 'price of electricity to mine a bitcoin' is clickbait. There is no fixed price as it's 100% market/demand driven. The way bitcoin works is that the difficulty of the algorithm automatically adjusts to the rate at whi

This thread, and site, tells the tale. Google is using this for marketing purposes. They already have some trite 2 minute marketing ad running as well. The deal that Twitter received is going to come with extensive incentives unavailable to

I think you phrase the grandparent's comment much better than he did. That is much more clear. Appreciated. But on housing, there's a major issue you're not considering. This [1] is a list of US city populations in 1950. This

It's interesting to consider the parallels between this stuff and the fountain of youth, or alchemists turning lead into gold. Explorers were constantly uncovering unimaginable new things with no real idea of where it might end. Simila

This leads to a possibility I'd not considered before. Trust in the media has deteriorated extensively. This seemed logically attributable to the rise of the internet thus ostensibly creating a race to publish, and publish sensationall

Evolution is only guided by survival alone in situations where as survival approaches 100%, so does fertility. In humans this is very much not the case for an immense number of reasons even beyond sexual selection. One of the biggest is sim

Of course it's going to be healthy but the more important question is sustainability. Some can keep up these sort of regimes, but for most that's a purely new years resolution style plan. By contrast very simple things like mostly

To be clear heritability is about the differences within individuals and not a raw value by itself. For instance if we have a trait with 80% heritability and one individual is measured at 120 against the average of 100, then this would me

There's a really peculiar aspect of IQ that many are not aware of. The heritability of IQ changes as you age - becoming more heritable over time. What this means is that environmental factors can play major differences in a youth'

I'd tend to agree, but I wonder if it's not really our priests getting better or smarter - but rather that this is the first time that the internet has brought issues to everybody's front door. For instance we all know about

Just found what seems to be a solid source [1] on the origin of the phrase. And it delivers. It was a sarcastic condemnation of the media pointing out the hypocrisy, misinformation, and so forth regularly printed in papers. It comes from on

One benchmark IBM recently passed is that it's now become a primarily Indian company in terms of overall workforce [1]. What this makes me wonder is how the distribution of roles works out. In other words when they fire older e.g. Amer

There's one major problem with apps of any sort of scale that involve any scenario where dangerous accidents are possible. The problem is that as these apps scale, these accidents will happen, and with a degree of regularity that als

The reason things like leaded fuel, cigarettes, DDT, CFCs (freon), and countless other conspiracies were so egregious is because 'influencers' were able to convince authoritative figures and the media to conspire in misleading the

You need to compare maternal obesity rates, not mean BMI. The two are not correlated because there are major biases in maternal demographics. For instance in the US most children born are now non-white and there is a strong inverse correlat

This article is extremely misleading. One of the main causes of infant mortality is parental obesity. [1] As America becomes more and more obese we're going to see more and more of these sort of consequences. For instance our declining

When a politician pushes for affordable housing, what is their motivation? We'd like to imagine it's altruistic and ideally in some cases it is. But in practice, there is near invariably a major political motivation. The 'job
