The only option left will be to purchase them at gun shows.

No license, no background check, no imposition on freedoms. Just a potentially lethal weapon purchased from a total stranger, perfectly within the law and right-wing "principles".

None of my desktops uses hibernate -- they are crunching numbers in the background 24/7. You may not need it even for laptops. Here's a link explaining the difference between hibernate and sleep, and how to free up that disk space:

Bible story of Sodom?

On an ordinary day some 3,600 years ago, the inhabitants of an ancient Middle Eastern city now called Tall el-Hammam [now identified with the Biblical city of Sodom] went about their daily business. They had no idea an unseen icy space rock was speeding toward them at about 38,000 mph (61,000 kph).

Flashing through the atmosphere, the rock exploded in a massive fireball about 2.5 miles (4 kilometers) above the ground. The blast was around 1,000 times more powerful than the Hiroshima atomic bomb. The shocked city dwellers who stared at it were blinded instantly. Air temperatures rapidly rose above 3,600 degrees Fahrenheit (2,000 degrees Celsius). Clothing and wood immediately burst into flames. Swords, spears, mudbricks and pottery began to melt. Almost immediately, the entire city was on fire.

Some seconds later, a massive shockwave smashed into the city. Moving at about 740 mph (1,200 kph), it was more powerful than the worst tornado ever recorded. The deadly winds ripped through the city, demolishing every building. They sheared off the top 40 feet (12 m) of the 4-story palace and blew the jumbled debris into the next valley. None of the 8,000 people or any animals within the city survived – their bodies were torn apart and their bones blasted into small fragments.

About a minute later, 14 miles (22 km) to the west of Tall el-Hammam, winds from the blast hit the biblical city of Jericho. Jericho’s walls came tumbling down and the city burned to the ground.

Getting answers required nearly 15 years of painstaking excavations by hundreds of people. It also involved detailed analyses of excavated material by more than two dozen scientists in 10 states in the U.S., as well as Canada and the Czech Republic. When our group finally published the evidence recently in the journal Scientific Reports, the 21 co-authors included archaeologists, geologists, geochemists, geomorphologists, mineralogists, paleobotanists, sedimentologists, cosmic-impact experts and medical doctors.

Here’s how we built up this picture of devastation in the past.

Water accelerates the process, by complexing reversibly with the iron atoms. So, a water solution of a chelating agent, exposed to air, would likely help accelerate rusting in the same way. I'm pretty sure the instructions say to wash and wipe it off thoroughly when you're done, and for good reason.

Coating steel tools with oil is the traditional way to prevent rust. Good mineral oil will do the job, though some vegetable oils are traditionally used. Camellia oil, for example, has long been used in Japan, but apparently mineral oil is better. One thing to try is to add a few percent of clove oil, or more economically, witch hazel oil*, to the mineral oil to inhibit bacterial growth which can accelerate rusting, though only woodworkers usually go this far, to protect their very expensive and very sharp tools.

You can even use spray vegetable oil: https://ucanr.edu/blogs/blogcore/postdetail.cfm?postnum=16760


* NOT witch hazel extract, which contains water and alcohol ! I have a huge bottle of witch hazel oil which I bought for under $3 at the drugstore years back. It works as well as the much more expensive clove oil (which is favored by dentists, because it comes into contact with sensitive tissues, without any harm).

Fauna and flora declared extinct

It’s a rare move for wildlife officials to give up hope on a plant or animal, but US government scientists say they've exhausted efforts to find these 23 species.

"OK" is the all-purpose American expression that became an all-purpose English expression that became an all-purpose expression in dozens of other languages. It can be an enthusiastic cheer (A parking spot! OK!), an unenthusiastic "meh" (How was the movie? It was…OK.), a way to draw attention to a topic shift (OK. Here's the next thing we need to do), or a number of other really useful things. It's amazing that we ever got along without it at all. But we did. Until 1839.

There may be more stories about the origin of "OK" than there are uses for it: it comes from the Haitian port "Aux Cayes," from Louisiana French au quai, from a Puerto Rican rum labeled "Aux Quais," from German alles korrekt or Ober-Kommando, from Chocktaw okeh, from Scots och aye, from Wolof waw kay, from Greek olla kalla, from Latin omnes korrecta. Other stories attribute it to bakers stamping their initials on biscuits, or shipbuilders marking wood for "outer keel," or Civil War soldiers carrying signs for "zero killed."

The truth about OK, as Allan Metcalf, the author of OK: The Improbable Story of America's Greatest Word, puts it, is that it was "born as a lame joke perpetrated by a newspaper editor in 1839." This is not just Metcalf's opinion or a half remembered story he once heard, as most OK stories are. His book is based in the thorough scholarship of Allen Walker Read, a Columbia professor who for years scoured historical sources for evidence about OK, and published his findings in a series of journal articles in 1963 to 1964.

It started with a joke

OK, here's the story. On Saturday, March 23, 1839, the editor of the Boston Morning Post published a humorous article about a satirical organization called the "Anti-Bell Ringing Society " in which he wrote:

The "Chairman of the Committee on Charity Lecture Bells," is one of the deputation, and perhaps if he should return to Boston, via Providence, he of the Journal, and his train-band, would have his "contribution box," et ceteras, o.k.—all correct—and cause the corks to fly, like sparks, upward.

It wasn't as strange as it might seem for the author to coin OK as an abbreviation for "all correct." There was a fashion then for playful abbreviations like i.s.b.d (it shall be done), r.t.b.s (remains to be seen), and s.p. (small potatoes). They were the early ancestors of OMG, LOL, and tl;dr. A twist on the trend was to base the abbreviations on alternate spellings or misspellings, so "no go" was k.g. (know go) and "all right" was o.w. (oll write). So it wasn't so surprising for someone come up with o.k. for oll korrect. What is surprising is that it ended up sticking around for so long while the other abbreviations faded away.

In 1989, David Bailey, a researcher in the field of clinical pharmacology (the study of how drugs affect humans), accidentally stumbled on perhaps the biggest discovery of his career, in his lab in London, Ontario. Follow-up testing confirmed his findings, and today there is not really any doubt that he was correct. “The hard part about it was that most people didn’t believe our data, because it was so unexpected,” he says. “A food had never been shown to produce a drug interaction like this, as large as this, ever.”
***
Eventually, with Bailey leading the effort, the mechanism became clear. The human body has mechanisms to break down stuff that ends up in the stomach. The one involved here is cytochrome P450, a group of enzymes that are tremendously important for converting various substances to inactive forms. Drugmakers factor this into their dosage formulation as they try to figure out what’s called the bioavailability of a drug, which is how much of a medication gets to your bloodstream after running the gauntlet of enzymes in your stomach. For most drugs, it is surprisingly little—sometimes as little as 10 percent.

Grapefruit has a high volume of compounds called furanocoumarins, which are designed to protect the fruit from fungal infections. When you ingest grapefruit, those furanocoumarins permanently take your cytochrome P450 enzymes offline. There’s no coming back. Grapefruit is powerful, and those cytochromes are donezo. So the body, when it encounters grapefruit, basically sighs, throws up its hands, and starts producing entirely new sets of cytochrome P450s. This can take over 12 hours.

This rather suddenly takes away one of the body’s main defense mechanisms. If you have a drug with 10 percent bioavailability, for example, the drugmakers, assuming you have intact cytochrome P450s, will prescribe you 10 times the amount of the drug you actually need, because so little will actually make it to your bloodstream. But in the presence of grapefruit, without those cytochrome P450s, you’re not getting 10 percent of that drug. You’re getting 100 percent. You’re overdosing.
***
Despite this, the Food and Drug Administration does not place warnings on many of the drugs known to have adverse interactions with grapefruit. Lipitor and Xanax have warnings about this in the official FDA recommendations, which you can find online and are generally provided with every prescription. But Zoloft, Viagra, Adderall, and others do not. “Currently, there is not enough clinical evidence to require Zoloft, Viagra, or Adderall to have a grapefruit juice interaction listed on the drug label,” wrote an FDA representative in an email.

People use the term “impossible” in a variety of ways. It can describe things that are merely improbable, like finding identical decks of shuffled cards. It can describe tasks that are practically impossible due to a lack of time, space or resources, such as copying all the books in the Library of Congress in longhand. Devices like perpetual-motion machines are physically impossible because their existence would contradict our understanding of physics.

Mathematical impossibility is different. We begin with unambiguous assumptions and use mathematical reasoning and logic to conclude that some outcome is impossible. No amount of luck, persistence, time or skill will make the task possible. The history of mathematics is rich in proofs of impossibility. Many are among the most celebrated results in mathematics. But it was not always so.

Many states require that districts be “compact,” a term with no fixed mathematical definition. In 1991, Daniel Polsby and Robert Popper proposed 4πA/P² as a way to measure the compactness of a district with area A and perimeter P. Values range from 1, for a circular district, to close to zero, for misshapen districts with long perimeters.

Meanwhile, Nicholas Stephanopoulos and Eric McGhee introduced the “efficiency gap” in 2014 as a measure of the political fairness of a redistricting plan. Two gerrymandering strategies are to ensure that the opposition party stays below the 50% threshold in districts (called cracking), or near the 100% level (stacking). Either tactic forces the other party to waste votes on losing candidates or on winning candidates who don’t need the votes. The efficiency gap captures the relative numbers of wasted votes.

Not much more on Gerrymandering, but lots of interesting background.

Financial pressures explain why many campuses have brought students back. But there is a textbook solution, two economists say: government intervention.

By Sarah Cohodes and Susan Dynarski

Oct. 8, 2020

A perfectly functioning market is a beautiful thing. It’s also vanishingly rare. The main work of economists is figuring out how to make markets function well when the messy, real world intrudes on our textbooks’ elegant models.

The pandemic, unfortunately, provides instructive examples of markets that are failing in predictable and harmful ways. The failures are particularly glaring in dozens of college towns across the United States that are coronavirus hot spots.

Introductory economics focuses on the “invisible hand of the market”: Independent actors, by pursuing their own interests, maximize the common good. In this idealized world, the best thing a government can do is get out of the way so the free market can work its magic.

But 95 percent of economics is about the imperfections of markets, and how the government can correct them. In fact, some market failures require government intervention for the invisible hand to do its work. Economic theory predicts when markets are likely to work with minimal intervention, and when they will fail without government involvement.

Pollution is the textbook example of a market failure. A manufacturer sending fumes into the air creates what economists call a “negative externality.” Simply by doing what it does — making its product — the firm harms others. Pollution reduces air quality for those living and breathing nearby, but since neighbors’ health doesn’t affect the bottom line that drives daily decisions at the factory, the pollution keeps flowing.

A pandemic is powered by the ultimate negative externality: The very act of breathing can spread a deadly disease.

The first few paras nicely sum up everything that's wrong with blind obeisance to the Invisible Bloody Hand of the Free Market.

In the 1980s, Howard-Yana Shapiro, now chief agricultural officer at Mars, Incorporated, was looking for new kinds of corn. He was in the Mixes District of Oaxaca in southern Mexico, the area where the precursors to maize (aka corn) first evolved, when he located some of the strangest corn ever seen. Not only was it 16 to 20 feet tall, dwarfing the 12-foot stuff in American fields, it took six to eight months to mature, far longer than the 3 months needed for conventional corn. Yet it grew to those impressive heights in what can charitably be called poor soil, without the use of fertilizer.. But the strangest part of the corn was its aerial roots--green and rose-colored, finger-like protrusions sticking out of the corn’s stalk, dripping with a clear, syrupy gel.

Shapiro suspected that those mucousy fingers might be the Holy Grail of agriculture. He believed that the roots allowed this unique variety of corn, dubbed Sierra Mixe and locally bred over hundreds or even thousands of years, to produce its own nitrogen, an essential nutrient for crops that is usually applied as fertilizer in epic amounts.

The idea seemed promising, but without DNA tools to look into the specifics of how the corn was making nitrogen, the discovery was shelved. Nearly two decades later, in 2005, Alan B. Bennett of the University of California, Davis—along with Shapiro and other researchers—began using cutting-edge technology to look into the nitrogen-fixing properties of the phlegmy corn, finding that indeed, bacteria living in the mucus were pulling nitrogen from the air, transmuting it into a form the corn could absorb.

Now, after over a decade of field research and genetic analysis, the team has published their work in the journal PLOS Biology. If the nitrogen-fixing trait could be bred into conventional corn, allowing it to produce even a portion of its own nitrogen, it could reduce the cost of farming, reduce greenhouse gas emissions and halt one of the major pollutants in lakes, rivers and the ocean. In other words, it could lead to a second nitrogen revolution.
***
Co-author Jean Michel-Ane from the University of Wisconsin, Madison, agrees that this discovery opens up all types of new possibilities. “Engineering corn to fix nitrogen and form root nodules like legumes has been a dream and struggle of scientists for decades. It turns out that this corn developed a totally different way to solve this nitrogen fixation problem. The scientific community probably underestimated nitrogen fixation in other crops because of its obsession with root nodules,” he says in a statement. “This corn showed us that nature can find solutions to some problems far beyond what scientists could ever imagine.”
