Where widely understood, I consider a Greek variable to be vastly superior. The problem is how well it's understood. Delta is an example of a succinct variable which has a well defined meaning which to encapsulate in a named variable either requires a long name or leaving out some nuance (delta isn't 'change' which is ambiguous in English, but the difference between two measurable things.)

Keep in mind we use special single letter variables all the time, sometimes multiple for the same concept. Multiply, divide, add, subtract. You learned them all in early education along with everyone else, and now you have a universal set of symbols to express arithmetic concepts.

Would we be better off if every occurrence of '+' was replaced with 'sum'? I don't think so, but that doesn't necessarily mean that loading up with single letter variables that people aren't familiar with is better. It's entirely to do with how familiar the target audience is with them. A library targeted for use by scientists might see benefit to more of them, while one targeted towards being accissible to many people might not.

To me, non pass/fail grades are pointless unless you're moving onto a higher degree, and professors are often silly about their requirements for passing a class.

I once took a discrete math class for CS majors. I aced it. Loved it. Classmates would ask me to explain concepts to them before exams if they were having trouble. There was only one other student in the class who had gotten an A on every exam leading up to the final. He had a problem that he didn't know about, though. He didn't turn in the homework.

Now, homework for this class was not a measure of skill. It was just a way for the professor to have an extra way to determine that you were participating. I warned him the class before the final that he was gonna fail if he didn't get the teacher to give him an extension on the homework, because I knew he wasn't turning it in (there was a requirement in the syllabus that you needed to turn in 70% of the homework to have a chance at passing). Hell, he was proud of the fact that he was smart enough to understand the course material without doing it. He didn't ask for the extension, and a year later, he was sitting in the same class for which he had already mastered the material.
Oh boy, I regret posting this, however down the rabbit hole we go...

> (psychopath -> male) ^ !(male -> psychopath)

I don't know what ^ means here, and !(m->p) is very different from (m/->p)

> to show how deducing (abnormal brain -> psychopath) from (psychopath -> abnormal brain) is flawed.

Is it? From <https://psychcentral.com/news/2012/05/11/scans-show-psychopa...

“Using MRI scans we found that psychopaths had structural brain abnormalities in key areas of their ‘social brains’ compared to those who just had ASPD,” he said.

He noted there is a clear difference between those with ASPD and those with ASPD+P.

“We describe those without psychopathy as hot-headed and those with psychopathy as cold-hearted,” he said.

“The cold-hearted psychopathic group begin offending earlier, engage in a broader range and greater density of offending behaviors, and respond less well to treatment programs in adulthood, compared to the hot-headed group. We now know that this behavioral difference corresponds to very specific structural brain abnormalities which underpin psychopathic behavior [my emphasis], such as profound deficits in empathizing with the distress of others.”

The researchers used magnetic resonance imaging (MRI) to scan the brains of 44 violent offenders diagnosed with ASPD. Crimes committed included murder, rape, attempted murder and grievous bodily harm. Of these, 17 met the diagnosis for psychopathy (ASPD+P) and 27 did not. Those that met the antisocial personality disorder but did not meet the psychopathy criteria (via the Psychopathy Checklist) were referred to as the ASPD-P group by the researchers. They also scanned the brains of 22 healthy non-offenders.

So they found a link, causal or not, between abnormalities and psychopathy, and they had a control group too.

> The systematic error of deducing a causality from correlation with under-sampling

I grant the control group here is small, but for you to claim it's 'under-sapled' is a bit cheeky. There seem to have been other studies too, from wikipedia "Blair, R. J. R. (2003). "Neurobiological basis of psychopathy". The British Journal of Psychiatry. 182 (1): 5–7. doi:10.1192/bjp.182.1.5. PMID 12509310." My guess is these people aren't so stupid as to overlook issues of under-sampling and mistaking correlation with causation.

> If you find that everyone in the extremely rare serial killer group has a particular brain abnormality [...] As serial-killers are very rare (as far as we can observe), the sample of the remaining population would need to be very large.

True, but psychopaths are neither rare nor automatically serial killers. If you're not equating them why did you mention serial killers?

> “This is not just a chase for cold fusion,” says Matthew Trevithick, a research programme manager at Google in Mountain View, California. “If it were, I don’t think we would have maintained an interest of this calibre of team for so long.”

Here's what I see: fusion power would be a step function in human civilization. Such step functions are pathologically hard to achieve, because new modes of thinking are hard for humans to do. Calling it cold fusion is a calling card to scientists who are serious about researching novel approaches to fusion instead of playing the politics of the research paper game. Will it work? Probably not. But that doesn't mean we shouldn't try. Also, from Google's perspective, if they're the company that owns the IP for fusion energy, that's a pretty massive win. Additionally, if they push just a few other companies into funding fusion research, then the odds that we see viable fusion energy production (not cold fusion) in our lifetimes probably increases. I would love to see a private industry race for fusion research, though, the financial requirements of such endeavors mean the game would only be open to a very small number of global megacorps. Still it would be better than not doing it.
You can't overtake oil without spending a comparable amount on developing renewables. While it isn't quite there yet, soon renewables will be a bigger business than oil. That's impressive, and it makes the kind of growth needed to replace nuclear power plausible.

Depends. Let's say, for the sake of argument, that Facebook runs servers in America (not canada). A canadian accesses their site and uses it. Is Facebook now "doing business" in canada? The problem with internet companies is that the rules are different: I no longer need any kind of physical presence to do business there (though servers are often necessary, but that's buying something not selling from a physical location).

It could definitely be bipartisan. I am a conservative and 100% support nuclear as an alternative to dirty coal. Unfortunately, many “environmentalists” seem to be stuck in the 1970s when it comes to knowledge about modern nuclear.
I have been thinking about setup and teardown for asyncio apps in Python lately.

The async with block is a nice idea but doesn't deal with the reality that often a resource has multiple consumers. For instance, there might be several components of an application that use a database connection -- I really want to make the connection once and tear it down only after all of the clients of that connection have themselves been torn down.

What I'm imagining the answer to be is something a little bit like the Spring Framework but fundamentally centered around asyncio.

> So not only do Americans get to wait twice as long, but they have to pay for it as well? You have to pay for ambulances? Why is this not politicized more?

Emergency services are run by the cities, or sometimes the states. And that's a completely reasonable thing to do -- if you have a heart attack in Los Angeles, they don't take you to an emergency room in Boston. Local people should control local stuff.

So you're asking the wrong question. It's not a matter of what happens in America, it's a matter of what happens in California, or Los Angeles. Other US cities have free ambulance service or shorter wait times.

The local people can change their local laws whenever they like.

People underestimated the extent to which markup may be mixed in from sources you didn't control, and the power that this ability gives to your users. Say you built a shiny new forum engine with from-scratch XHTML markup. You try to sell it. Most of your customers say that they've already been running forum software since 1995 but the existing posts allow inline HTML (which was less unsafe in 1995, because no Javascript), which is all badly misnested. As soon as they dump the previous data, their site stops working.

Or you import a small Javascript library from 1999 that generates its own innerHTML for a few elements, but does it with HTML. Oops.

Or you built a new CMS with shiny XHTML markup, but before you had the CMS your org just hand-wrote pages which you now need to parse and import into the CMS.

These were all very real considerations in the 2002-2004 period; I've dealt with all of them.

I had a history professor who gave a test in this manner: Below there are 3 columns of 14 items of interest, whether they be people or wars or treaties or whatever. You are allowed to cross out 2 columns, and then cross out 3 terms. Write what you know about the remaining terms. Your grade is out of 110 on a 100 point scale.

Now, I loved the test, because I excel at soft trivia tests... but did it really gauge what I understood about history?

Nope. It gauged my knowledge of history trivia for those terms. Understanding history is about understanding how these things connect together.

If I were a history professor, I would base the majority of students' grades on papers about the subjects we cover in class to discover whether they're actually thinking about history or if they're just trying to recite facts and figures.
Yes and it's interesting to quote the rest of that paragraph, which ends up arguing that clean energy transitions "would end up hurting consumers through higher electricity bills."[1]

The use of the term "hurting" here is a tell. Yeah, you know, maybe fixing the planet will require a mobilization on the scale of going to war and result in higher prices. That's not hurting people; that's helping our children live on a planet free of nuclear waste and climate disaster.

[1] "Such a drastic increase in renewable power generation would create serious challenges in integrating the new sources into the broader energy system. Clean energy transitions in advanced economies would also require $1.6 trillion in additional investment over the same period, which would end up hurting consumers through higher electricity bills."

> think that correlation does imply causality

You know, despite the trope sometimes it does. Does it here? From wikipedia <https://en.wikipedia.org/wiki/Psychopathy>:

Blair, a researcher who pioneered research into psychopathic tendencies stated, “With regard to psychopathy, we have clear indications regarding why the pathology gives rise to the emotional and behavioral disturbance and important insights into the neural systems implicated in this pathology”.

From the same wiki article

Researchers have linked head injuries with psychopathy and violence. Since the 1980s, scientists have associated traumatic brain injury, such as damage to the prefrontal cortex, including the orbitofrontal cortex, with psychopathic behavior and a deficient ability to make morally and socially acceptable decisions, a condition that has been termed "acquired sociopathy", or "pseudopsychopathy".[72] Individuals with damage to the area of the prefrontal cortex known as the ventromedial prefrontal cortex show remarkable similarities to diagnosed psychopathic individuals, displaying reduced autonomic response to emotional stimuli, deficits in aversive conditioning, similar preferences in moral and economic decision making, and diminished empathy and social emotions like guilt or shame

> There's no more reason to think prefontal cortex anomaly causes psychopathy than being male does.

It seems experts think otherwise.

> the correct amount of federalization... may be significantly greater than seemed

Wrong. This is why the Constitution enumerates a few, very specific powers and says that the rest are reserved to the states and to the people.

> Radical minimization of the federal power was the design of the Articles of Confederation

Wrong. Congress couldn't even regulate foreign trade; there was no federal power. When the federal government cannot represent the nation as a whole to foreign powers, there is no true federal government. We moved to a Constitution with minimum federal power because that solution didn't work.
I've been a Fort Worth resident for nearly 4 years.

Anecdotal, but my old neighborhood (far south - near Crowley) had tons of residential solar (relatively speaking - probably 1/6 of the homes). It was a new development with no mature trees. TXU actually has a pretty attractive [residential solar program](https://www.txu.com/savings-solutions/renewable-energy/solar...) that lots of my neighbors took advantage of.

I've since bought a house built in the 60s. My new neighborhood (Ridglea) has lots of mature trees. There is no way solar would work here. My roof only gets sunlight for a couple of hours a day.
