Skin turgor: MedlinePlus Medical Encyclopedia
To check for skin turgor, the health care provider grasps the skin between two fingers so that it is tented up. Commonly on the lower arm or abdomen is checked. The skin is held for a few seconds then released.

Skin with normal turgor snaps rapidly back to its normal position. Skin with poor turgor takes time to return to its normal position.

What does it mean when a CSS rule is grayed out in Chrome's element inspector? - Stack Overflow
It seems that a strike-through indicates that a rule was overridden, but what does it mean when a style is grayed out?

--

Greyed/dimmed out text, can mean either

1. it's a default rule/property the browser applies, which includes defaulted short-hand properties.
2. It involves inheritance which is a bit more complicated.

...

In the case where a rule is applied to the currently selected element due to inheritance (i.e. the rule was applied to an ancestor, and the selected element inherited it), chrome will again display the entire ruleset.

The rules which are applied to the currently selected element appear in normal text.

If a rule exists in that set but is not applied because it's a non-inheritable property (e.g. background color), it will appear as greyed/dimmed text.

https://stackoverflow.com/questions/34712218/what-does-it-mean-when-chrome-dev-tools-shows-a-computed-property-greyed-out
Please note, not the Styles panel (I know what greyed-out means in that context—not applied), but the next panel over, the Computed properties panel.
--
The gray calculated properties are neither default, nor inherited. This only occurs on properties that were not defined for the element, but _calculated_ from either its children or parent _based on runtime layout rendering_.

Take this simple page as an example, display is default and font-size is inherited:

Why You Should Learn Cultures, Not Languages | LinkedIn
Given the nature of my work, I’m constantly asked what languages people should invest their energies learning. If you do have a knack for languages, and lots of time on your hands, study Chinese. It’s a business language of the future, and China remains the most politically disruptive force in the world order today. That’s where the smart money is.

But looking back, I would have spent less time on learning a language. Seriously. Though I studied Russian for many years, my Russian skills have atrophied over time. What remains is the insight I gathered into the mentality, familiarizing myself with how other people in the world live by interacting with them directly. That’s never gone away. It gave me the type of perspective that remains critical to my work to this day.

A lot has changed since those days. The rise of technology plays a big role in the advice I’m handing out here. Technology will soon make language barriers obsolete, probably in the next five to 10 years. Google Translate has already removed most of the barriers of the written word, though with occasionally hilarious results, and new generations of smartphone apps will do the same for verbal communication in short order. Of course, it’s important to show people that you care enough about their country to learn their language.

Regex cheatsheet
Many programs use regular expression to find & replace text. However, they tend to come with their own different flavor.

You can probably expect most modern software and programming languages to be using some variation of the Perl flavor, "PCRE"; however command-line tools (grep, less, ...) will often use the POSIX flavor (sometimes with an extended variant, e.g. egrep or sed -r). ViM also comes with its own syntax (a superset of what Vi accepts).

This cheatsheet lists the respective syntax of each flavor, and the software that uses it.

Science - Wikipedia
In Northern Europe, the new technology of the printing press was widely used to publish many arguments, including some that disagreed widely with contemporary ideas of nature. René Descartes and Francis Bacon published philosophical arguments in favor of a new type of non-Aristotelian science. Descartes emphasized individual thought and argued that mathematics rather than geometry should be used in order to study nature. Bacon emphasized the importance of experiment over contemplation. Bacon further questioned the Aristotelian concepts of formal cause and final cause, and promoted the idea that science should study the laws of "simple" natures, such as heat, rather than assuming that there is any specific nature, or "formal cause," of each complex type of thing. This new modern science began to see itself as describing "laws of nature". This updated approach to studies in nature was seen as mechanistic. Bacon also argued that science should aim for the first time at practical inventions for the improvement of all human life.

Age of Enlightenment

...

During this time, the declared purpose and value of science became producing wealth and inventions that would improve human lives, in the materialistic sense of having more food, clothing, and other things. In Bacon's words, "the real and legitimate goal of sciences is the endowment of human life with new inventions and riches", and he discouraged scientists from pursuing intangible philosophical or spiritual ideas, which he believed contributed little to human happiness beyond "the fume of subtle, sublime, or pleasing speculation".[72]

The Space Trilogy - Wikipedia
Out of the Silent Planet:

Weston makes a long speech justifying his proposed invasion of Malacandra on "progressive" and evolutionary grounds, which Ransom attempts to translate into Malacandrian, thus laying bare the brutality and crudity of Weston's ambitions.

Oyarsa listens carefully to Weston's speech and acknowledges that the scientist is acting out of a sense of duty to his species, and not mere greed. This renders him more mercifully disposed towards the scientist, who accepts that he may die while giving Man the means to continue. However, on closer examination Oyarsa points out that Weston's loyalty is not to Man's mind – or he would equally value the intelligent alien minds already inhabiting Malacandra, instead of seeking to displace them in favour of humanity; nor to Man's body – since, as Weston is well aware of and at ease with, Man's physical form will alter over time, and indeed would have to in order to adapt to Weston's programme of space exploration and colonisation. It seems then that Weston is loyal only to "the seed" – Man's genome – which he seeks to propagate. When Oyarsa questions why this is an intelligible motivation for action, Weston's eloquence fails him and he can only articulate that if Oyarsa does not understand Man's basic loyalty to Man then he, Weston, cannot possibly instruct him.

...

Perelandra:

The rafts or floating islands are indeed Paradise, not only in the sense that they provide a pleasant and care-free life (until the arrival of Weston) but also in the sense that Ransom is for weeks and months naked in the presence of a beautiful naked woman without once lusting after her or being tempted to seduce her. This is because of the perfection in that world.

The plot thickens when Professor Weston arrives in a spaceship and lands in a part of the ocean quite close to the Fixed Land. He at first announces to Ransom that he is a reformed man, but appears to still be in search of power. Instead of the strictly materialist attitude he displayed when first meeting Ransom, he asserts he had become aware of the existence of spiritual beings and pledges allegiance to what he calls the "Life-Force." Ransom, however, disagrees with Weston's position that the spiritual is inherently good, and indeed Weston soon shows signs of demonic possession.

In this state, the possessed Weston finds the Queen and tries to tempt her into defying Maleldil's orders by spending a night on the Fixed Land. Ransom, perceiving this, believes that he must act as a counter-tempter. Well versed in the Bible and Christian theology, Ransom realises that if the pristine Queen, who has never heard of Evil, succumbs to the tempter's arguments, the Fall of Man will be re-enacted on Perelandra. He struggles through day after day of lengthy arguments illustrating various approaches to temptation, but the demonic Weston shows super-human brilliance in debate (though when "off-duty" he displays moronic, asinine behaviour and small-minded viciousness) and moreover appears never to need sleep.

With the demonic Weston on the verge of winning, the desperate Ransom hears in the night what he gradually realises is a Divine voice, commanding him to physically attack the Tempter. Ransom is reluctant, and debates with the divine (inner) voice for the entire duration of the night. A curious twist is introduced here; whereas the name "Ransom" is said to be derived from the title "Ranolf's Son", it can also refer to a reward given in exchange for a treasured life. Recalling this, and recalling that his God would (and has) sacrificed Himself in a similar situation, Ransom decides to confront the Tempter outright.

Ransom attacks his opponent bare-handed, using only physical force. Weston's body is unable to withstand this despite the Tempter's superior abilities of rhetoric, and so the Tempter flees. Ultimately Ransom chases him over the ocean, Weston fleeing and Ransom chasing on the backs of giant and friendly fish. During a fleeting truce, the "real" Weston appears to momentarily re-inhabit his body, and recount his experience of Hell, wherein the damned soul is not consigned to pain or fire, as supposed by popular eschatology, but is absorbed into the Devil, losing all independent existence.

bash - Queue up commands while one command is being executed - Unix & Linux Stack Exchange
Press Ctrl+Z and immediately run bg. This causes the current command to keep running in the background. Then you can use fg && otherCommand to schedule otherCommand after the current one.

To make this easier, I've configured Ctrl+Z in my shell to run bg when I press it on an empty command line. See In zsh, how can I more quickly disown the foreground process? and How do you send command line apps directly to the background? ; I haven't checked if modern versions of bash make it easy to do the same.

The Greatest Generation | West Hunter
But  when you consider that people must have had 48 chromosomes back then, rather than the current measly 46, much is explained.

Theophilus Painter, a prominent cytologist, had investigated human chromosome number in 1923. He thought that there were 24 in sperm cells, resulting in a count of 48, which is entirely reasonable. That is definitely the case for all our closest relatives (chimpanzees, bonobos, gorillas, and orangutans).

The authorities say that that Painter made a mistake, and that humans always had 46 chromosomes. But then, for 30 years after Painter’s work, the authorities said that people had 48.  Textbooks in genetics continued to say that Man has 48 chromosomes up until the mid 1950s.  Many cytologists and geneticists studied human chromosomes during that period, but they knew that there were 48, and that’s what they saw. Now they know that there are 46, and that’s what every student sees.

Either the authorities are fallible and most people are sheep, or human chromosome number actually changed sometime after World War II.  No one could believe the first alternative: it would hurt our feelings, and therefore cannot be true.  No, we have a fascinating result: people today are fundamentally different from the Greatest Generation, biologically different: we’re two chromosomes shy of a load. .    So it’s not our fault !

“some social environments are better than others at extracting the best from its people”

That’s very true – we certainly don’t seem to be doing a very good job of it. It’s a minor matter, but threatening brilliant engineers with death or professional ruin because of their sexist sartorial choices probably isn’t helping…

I used to do some engineering, and if someone had tried on that on me, I’ve have told him to go fuck itself. Is that a lost art?

Prevalence of doping use in elite sports: a review of numbers and methods. - PubMed - NCBI
These period prevalences have been found in specific sub-groups of elite athletes, and the available data suggest that the prevalence of doping is considerably different between sub-groups with varying types of sport, levels and nationalities. The above-mentioned figure of 14-39% is likely to be a more accurate reflection of the prevalence of intentional doping in elite sports than that provided by doping control test results (estimate of doping: 1-2% annually) or questionnaire-based research (estimations between 1 and 70% depending on sport, level and exact definitions of intent and doping).

Dream Jobs That You’re Glad You Didn’t Pursue: Column 7: So You Wanted to be President of the United States… - McSweeney’s Internet Tendency
Somewhere along the line it stopped bothering you altogether that you had sold your soul and you actually believed yourself when you talked about your work as a function of the greater good. The only thing that bothered you in fact was that it was tedious to go through the motions of a campaign every six years, but you had to make a show of it, mustering every ounce of humility you could, for the voters. To eliminate this bother you decided to set your sights on the cushiest job in government, and the real seat of power in the United States. Your decision long ago to pursue the law would serve you well on the Supreme Court.

Dogs and Men | West Hunter
Razib Khan talks about a new article that suggests that dogs were domesticated quite a long time ago, perhaps more than 35,000 years ago, well before the last glacial maximum.

We know that dogs have adapted to life with people, have changed in many ways.

I wonder how humans adapted to dogs.  If they were like modern pariah dogs, hanging around the village and eating garbage, doesn’t seem that they would have been that influential. But if used in hunting, they could have been very important, especially back in the Ice Age – and if they were that important, the partnership might have generated significant selective pressures in humans.

The Garden of Earthly Delights - Wikipedia
The Garden of Earthly Delights is the modern title[1] given to a triptych painted by the Early Netherlandish master Hieronymus Bosch, housed in the Museo del Prado in Madrid since 1939. It dates from between 1490 and 1510, when Bosch was between about 40 and 60 years old,[2] and is his best-known and most ambitious surviving work.

The triptych is painted in oil on oak and is composed of a square middle panel flanked by two other oak rectangular wings that close over the center as shutters. The outer wings, when folded, show a grisaille painting of the earth during the biblical narrative of Creation. The three scenes of the inner triptych are probably (but not necessarily) intended to be read chronologically from left to right. The left panel depicts God presenting Eve to Adam, the central panel is a broad panorama of socially engaged nude figures, fantastical animals, oversized fruit and hybrid stone formations. The right panel is a hellscape and portrays the torments of damnation.

Gummo - Wikipedia
Gummo is a 1997 American dystopian art film written and directed by Harmony Korine, starring Jacob Reynolds, Nick Sutton, Jacob Sewell, and Chloë Sevigny. The film is set in Xenia, Ohio, a small, poor Midwestern American town that had been previously struck by a devastating tornado. The loose narrative follows several main characters who find odd and destructive ways to pass time, interrupted by vignettes depicting other inhabitants of the town.

Wiring the Brain: The dark arts of statistical genomics
GCTA+GWAS

This is where GCTA analyses come in. The idea here is to estimate the total contribution of common risk variants in the population to determining who develops a disease, without necessarily having to identify them all individually first. The basic premise of GCTA analyses is to not worry about picking up the signatures of individual SNPs, but instead to use all the SNPs analysed to simply measure relatedness among people in your study population. Then you can compare that index of (distant) relatedness to an index of phenotypic similarity. For a trait like height, that will be a correlation between two continuous measures. For diseases, however, the phenotypic measure is categorical – you either have been diagnosed with it or you haven’t.
