Earth’s magnetic field is acting up and geologists don’t know why

Something strange is going on at the top of the world. Earth’s north magnetic pole has been skittering away from Canada and towards Siberia, driven by liquid iron sloshing within the planet’s core. The magnetic pole is moving so quickly that it has forced the world’s geomagnetism experts into a rare move.

On 15 January, they are set to update the World Magnetic Model, which describes the planet’s magnetic field and underlies all modern navigation, from the systems that steer ships at sea to Google Maps on smartphones.

The most recent version of the model came out in 2015 and was supposed to last until 2020 — but the magnetic field is changing so rapidly that researchers have to fix the model now. “The error is increasing all the time,” says Arnaud Chulliat, a geomagnetist at the University of Colorado Boulder and the National Oceanic and Atmospheric Administration’s (NOAA’s) National Centers for Environmental Information.

Repair Cafes Aim to Fix Our Throwaway Culture – CityLab

Repair cafes. What a brilliant idea!

We were at a “repair cafe” inside the Elkridge Library in Howard County, Maryland. Instead of silence, we were surrounded by the buzzing of power drills and the whirring of sewing machines. Goedeke was one of the “master fixers” there. He doesn’t like the term, though; he says it should be reserved for the professionals. “We’re all just amateurs at this, and we’re just having fun, mostly,” the 67-year-old retired engineer said.

Around the room, 10 others were helping residents repair everything from tables and lamps to jewelry and clothing. In one corner, a handful of vacuums had begun to accumulate. These were things people normally threw away when they malfunction. “[Our society] has been inculcated in the last 50 years with this disposable concept and to buy the best and the latest,” Goedeke said. “We just don’t expect to keeps things around.”

26 Years of Growth: Shanghai Then and Now – The Atlantic

Reuters photographer Carlos Barria recently spent time in Shanghai, China, the fastest-growing city in the world. A week ago, he took this amazing shot, recreating the same framing and perspective as a photograph taken in 1987, showing what a difference 26 years can make. The setting is Shanghai’s financial district of Pudong, dominated by the Oriental Pearl Tower at left, and the new 125-story Shanghai Tower, China’s tallest building and the world’s second tallest skyscraper, at 632 meters (2,073 ft) high, scheduled to finish by the end of 2014. Shanghai, the largest city by population in the world, has been growing at a rate of about 10 percent a year the past 20 years, and now is home to 23.5 million people — nearly double what it was back in 1987. This entry is focused on this single photo pairing, with several ways to compare the two.

It Was Vulture Capitalism that Killed Sears

If you’ve been following the impending bankruptcy of America’s iconic retailer, as covered by print, broadcast, and digital media, you’ve probably encountered lots of nostalgia, and sad clucking about how dinosaurs like Sears can’t compete in the age of Amazon and specialty retail.

But most of the coverage has failed to stress the deeper story. Namely, Sears is a prime example of how hedge funds and private-equity companies take over retailers, encumber them with debt in order to pay themselves massive windfall profits, and then leave the retailer without adequate operating capital to compete. Part of the strategy is to sell off valuable real estate, the better to enrich the hedge fund, and stick the retail company with costly rental payments to occupy the space that it once owned.

‘Hyperalarming’ study shows massive insect loss – The Washington Post

Insects around the world are in a crisis, according to a small but growing number of long-term studies showing dramatic declines in invertebrate populations. A new report suggests that the problem is more widespread than scientists realized. Huge numbers of bugs have been lost in a pristine national forest in Puerto Rico, the study found, and the forest’s insect-eating animals have gone missing, too.

In 2014, an international team of biologists estimated that, in the past 35 years, the abundance of invertebrates such as beetles and bees had decreased by 45 percent. In places where long-term insect data are available, mainly in Europe, insect numbers are plummeting. A study last year showed a 76 percent decrease in flying insects in the past few decades in German nature preserves.

After Soyuz Failure, Space Is Now Weirdly Inaccessible to Astronauts

All crewed launches have been suspended by Russia’s space agency following yesterday’s Soyuz rocket failure. That’s a problem, because much of the world relies on Russian rockets to get both cargo and people into space. Consequently, we’re now facing the very real possibility of having an uncrewed International Space Station—something that hasn’t happened in nearly two decades.

China Snuck Chips Into CIA, U.S. Military, Commercial Servers Leaving Them Open To Hacks: Report – The Drive

China seems willing to gamble its huge manufacturing industry in service to its spying. Why should foreign companies trust their manufacturing to China anymore? Regardless of the economic price China will pay for this, it can never be fully trusted again.

A new report is alleging the Chinese government directly interceded to insert small microchips into motherboards from a company called Supermicro, that are in use in servers everywhere from the adult film industry to U.S. military and U.S. Intelligence Community data centers, which make them vulnerable open them up to remote hacks. If the claims turn out to be true, it would be an intelligence operation of historic proportions that would have far-reaching and long-lasting ramifications.

On Oct. 4, 2018, Bloomberg Businessweek published its story, which is the culmination of years of investigative work and cites nearly 20 anonymous sources from both the U.S. government and private companies reportedly involved in the affair. The piece says that American authorities first became aware of the existence of the chips in 2015, that the classified probe is still ongoing, and that U.S. officials have identified an unspecified unit of the People’s Liberation Army (PLA) as being responsible for sneaking the malicious hardware into the servers.

Jailbirds: Scooters and Sidewalks

Bird Scooter

As most residents are now aware, a few weeks ago the city of Raleigh become one of the few lucky (?) municipalities to get rentable electric scooters. These scooters (mostly of the Bird brand at this point) have been zipping merry residents from one end of town to the other for a small fee. While many are pleased that this new mobility choice has possibly decreased the number of car trips, others have pointed to the dockless nature of the scooters and how this inevitably leads to the scooters blocking sidewalks.

The City Council has not yet weighed in on the legality of scooters making their home on the sidewalks without having first been given official permission. Thus, they are operating in kind of a gray area. I decided to look into the Raleigh Municipal Code to see what laws we have on the books regarding sidewalks and motor vehicles.

It didn’t take long to find the relevant section in the Raleigh Municipal Code (and conveniently linked to from the links page of my EastRaleigh.Org website – I am awesome). Emphasis is mine:

Sec. 11-2171. – PARKING PROHIBITED IN CERTAIN PLACES.

(a) Obstructing traffic.

It shall be unlawful for any person to stop, stand or park any motor vehicle upon a street , or alley, in such manner or under such conditions as to obstruct the free movement of vehicular traffic, except that a driver may stop temporarily during the actual unloading of passengers or when necessary to obey traffic regulations or signs or signals, or signals of a police officer .

(b) Designated places.

No person shall stop, stand or park a motor vehicle (attended or unattended) except when necessary to avoid conflict with other traffic or in compliance with the directions of a police officer or traffic-control device in any of the following places:

(1) On a sidewalk, in the area between the roadway and the sidewalk, in the area between the right-of-way line and the roadway or in the median area of a divided roadway

The peddlers of fear and outrage

Trash your TV

Two things took place during my hospital visits with my Dad this week. One was becoming captivated with an unlikely Trump voter. The other was gaining some insight into how he got that way.

I visited my Dad when the nightly news was on. Our local ABC affiliate, WTVD, was ticking through its top stories from around the country. Dad soon changed the channel and offhandedly stated his reasoning.

It was all about crime. Robberies, murders, carjackings, shootings. For some reason, our local affiliate thought it important to alarm us with news of misfortunes that took place hundreds, or in some cases, thousands of miles away, far from any possibility of them affecting us.

Why was the news doing this? Was it just laziness, being that chasing a cop or an ambulance is an easy way to a story? If there was airtime to fill, why weren’t there more local stories to fill it? Why fill viewers’ heads with stories that have no practical value?

Unless the point is to … stoke fear?

I’d been thinking lately that many Trump voters seem to be under some sort of spell. That’s one way I can account for the cognitive dissonance. Why do these folks seem so fearful all the time, thinking the boogeyman is at their door?

The answer was staring me in the face. It’s the television coverage.
