A Drone Tried to Disrupt the Power Grid. It Won’t Be the Last

An attack attempt in 2020 proves the UAS threat is real—and not enough is being done to stop it.

Today marks the official retail availability of Intel’s 12th Generation Core processors, starting with the overclockable versions this side of the New Year, and the rest in 2022. These new processors are the first widescale launch of a hybrid processor design for mainstream Windows-based desktops using the underlying x86 architecture: Intel has created two types of core, a performance core and an efficiency core, to work together and provide the best of performance and low power in a singular package. This hybrid design and new platform however has a number of rocks in the river to navigate: adapting Windows 10 Windows 11 and all sorts of software to work properly, but also introduction of DDR5 at a time when DDR5 is still not widely available. There are so many potential pitfalls for this product, and we’re testing the flagship Core i9-12900K in a few key areas to see how it tackles them.
Let’s Talk Processors
Since August, Intel has been talking about the design of its 12th Generation Core processor family, also known as Alder Lake. We’ve already detailed over 16,000 words on the topic, covering the fundamentals of each new core, how Intel has worked with Microsoft to improve Windows performance with the new design, as features like DDR5, chipsets, and overclocking. We’ll briefly cover the highlights here, but these two articles are worth the read for those that want to know.
It’s been a tumultuous 12 months for mainland China’s richest. Shifts in government policy covering the education and tech industries, along with worries about real estate debt, led to many of the country’s largest private-sector companies experiencing steep share declines. A government push to promote “common prosperity” saw tycoons and tech companies announce billions of dollars in donations to social causes.
Yet overall, China’s 100 Richest saw their collective net worth rise from last year’s list. Their total wealth increased to $1.48 trillion from $1.33 trillion a year earlier. Among the biggest gainers were those who benefited from increased sales at companies tied to green energy industries in which China is a global leader, such as lithium-ion batteries. China, the world’s largest auto market, also leads the world in EV sales. The minimum net worth to make the top 100 rose to $5.74 billion from $5.03 billion a year ago.
The second-biggest increase in wealth went to Robin Zeng, chairman of battery-maker Contemporary Amperex Technology, whose fortune increased to $50.8 billion from $20.1 billion last year. That earned him the No. 3 spot on this year’s list.
A video on possible examples of how a government can try to manipulate is populace. It may be good to be more aware of its dangers.
Chinese citizens are being told to treat the USA and the Outside world as the Enemy, they’re being prepared for war whilst we tiptoe around worrying about hurting the feelings of the Chinese government… Time to wake up.

Something is killing-off galaxies by preventing the birth of stars—and astronomers now think they know why.
While studying 51 galaxies in a “galaxy-cluster” called the Virgo Cluster an international team of scientists have found that molecular gas—the fuel for new stars—is being “swept away by a huge cosmic broom.”
Exactly what is preventing nearby galaxies from birthing new stars has been a long-standing mystery in astrophysics. The new paper, now available online, blames the extreme environment of the Virgo Cluster. It’s been accepted by the journal Astrophysical Journal Supplement Series.
The interest of the US air force has been caught by the tech company Twelve’s project that allows the manufacture of a carbon-neutral aviation fuel called E-Jet. It can be used at any place, and it uses carbon dioxide from the air, water, and renewable energy.
Usually, the supply lines of energy, fuel, and water are the main targets for the opposing forces. The US Air Force stated that the attacks on fuel and water convoys in Afghanistan amounted to 30 percent of coalition casualties.
This process is being called “industrial photosynthesis” and makes use of the polymer electrolyte membrane electrolysis. It is a kind of inverted fuel cell, with a metal catalyst installed on a cathode to break down carbon dioxide and water into their component ions and then convert them into oxygen, hydrogen, and carbon monoxide.
Solar activity can heat up so much, in fact, that the Sun’s magnetic poles end up flipping, blasting off massive amounts of solar material in the process.
The strongest X-class solar flare ever recorded was an X28-class flare, meaning that it was 28 times more powerful than the October 28 flare, according to NASA. It may have been even more powerful than that, as the sensors cut out at that level.
These events are the biggest explosions in the solar system and can release as much energy as a billion hydrogen bombs, according to NASA. So even though the Sun enables life on Earth, don’t ever forget its potential for terrible destruction as well.
Wellington International Airport officials believe it may be the longest distance flown in an electric plane across any body of water.
“It’s a very exciting day for the airport. A world-record-setting day,” said spokesperson Jenna Raeburn.

China’s economy — the 2nd-largest in the world — is teetering on the brink of disaster.
Since this spring, Beijing has canceled initial public offerings, fined tech companies billions for antitrust violations, forcibly shut down China’s entire for-profit education industry, and sent CEOs running for the exits to avoid the government’s ire. Even more dire, the Chinese megadeveloper Evergrande recently started missing payments on its more than $300 billion in debt, shaking global markets. The convulsions have woken the world up to a startling new possibility — that Beijing may be willing to allow some of its private corporate behemoths to collapse in a bid to reshape the economic model that made China a superpower.
We have developed an absolute radiometer to measure laser power by means of radiation pressure in a closed control-loop configuration using diamagnetically levitated pyrolytic graphite as the soft spring and gravity as a contactless restoring force. Our approach takes advantage of an extremely low spring stiffness (2.95 mN/m) afforded by diamagnetic levitation above a permanent magnet array and a lock-in amplifier in the feedback loop to attain a 30mWrms noise. A horizontally directed laser beam impinges on a highly reflective dielectric stack mirror mounted on the levitating pyrolytic graphite shuttle. The light’s momentum displaces the shuttle, and its position is restored by tilting the magnet array with a piezoelectric actuator. The closed-loop configuration avoids the need for accurate knowledge of the system spring stiffness or environmental dependencies of the diamagnetic levitation. Absolute laser power measured is traceable to the mass of the diamagnetically levitating shuttle system, the local gravitational acceleration, and the interferometrically measured tilt angle of the magnet array. The system is demonstrated with a laser power of 2.7 W, yielding a combined relative expanded uncertainty (k=2) of 1.9%. The upper limit of measurable power is determined by the range of the piezoelectric actuator, and the minimum power is currently limited by the noise floor that is constrained by air currents.
