Astronomers may have discovered first planet to orbit 3 stars:

In a distant star system — a mere 1,300 light years away from Earth — UNLV researchers and colleagues may have identified the first known planet to orbit three stars.

[...] Using observations from the powerful Atacama Large Millimeter/submillimeter Array (ALMA) telescope, UNLV astronomers analyzed the three observed dust rings around the three stars, which are critical to forming planets.

But they found a substantial, yet puzzling, gap in the circumtriple disc.

The research team investigated different origins, including the possibility that the gap was created by gravitational torque from the three stars. But after constructing a comprehensive model of GW Ori, they found that the more likely, and fascinating, explanation for the space in the disc is the presence of one or more massive planets, Jupiter-like in nature. Gas giants, according to Jeremy Smallwood, lead author and a recent Ph.D. graduate in astronomy from UNLV, are usually the first planets to form within a star system. Terrestrial planets like Earth and Mars follow.

GW Orionis.

Windows 11 will hobble gaming performance by default on some prebuilt PCs:

Despite Microsoft's claims that "if you're a gamer, Windows 11 was made for you" you will need to watch out for future prebuilt PCs with the new OS factory installed. That's because the Big M is enabling more security features in PCs by default, and one in particular can seriously tank gaming performance.

In our testing, that can add up to as much as a 28% drop in average frame rates. And you thought the TPM 2.0 restrictions were a pain...

That sort of frame rate delta is like dropping down an entire tier of graphics card and, in these days where GPUs are so hard to come by, Microsoft gimping the performance of the chip in your newbuild machine would surely be hard for gamers to stomach.

The issue is Virtualization-Based Security (VBS), a setting introduced into Windows 10 which uses hardware and software virtualisation to enhance the security of your system. It basically creates an isolated subsystem that helps prevent malware from screwing your PC.

Samsung Electronics close to finalising $17 bln Texas chip plant -sources

Samsung Electronics Co Ltd (005930.KS) is close to finalising the construction of a $17 billion semiconductor factory in Williamson County in the U.S. state of Texas, three people with knowledge of the matter said.

Samsung told Reuters that it is continuing due diligence in multiple locations, and that it has yet to make a decision.

The factory will make advanced logic semiconductor chips and is likely to create about 1,800 jobs, Samsung previously said in filings to state officials.

One of the people said though no decision has been made, the Austin suburb of Williamson County is the frontrunner due to the subsidies on offer as well as the likelihood of stable sources of electricity and water.

A winter storm shutdown at Samsung's existing chip plant in Austin during the first quarter caused the equivalent of 300 billion to 400 billion won ($254 million to $339 million) of damage to wafer production.

The $10 billion "3nm" fab plan mentioned earlier in the year may be referring to a different fab.

Archive link: https://archive.is/VtKFt

When LED lightbulbs supplanted old-fashioned Edisons, it was with a promise of greater energy efficiency and remarkable longevity.

According to the U.S. Department of Energy, LEDs use at least 75% less power than incandescent bulbs and last up to 25 times longer.

But it's not clear how long the modern lights last outside of ideal laboratory conditions, and in certain circumstances, they might not outlive the traditional bulbs they bumped off the shelf.

"A lot of expectations have been created that if you buy an LED lightbulb, you don't have to change it ever," said Nadarajah Narendran, director of research at Rensselaer Polytechnic Institute's Lighting Research Center. "It's time for us to reset those expectations."

S.Korea broadband firm sues Netflix after traffic surge from 'Squid Game':

SEOUL, Oct 1 (Reuters) - South Korean Internet service provider SK Broadband has sued Netflix (NFLX.O) to pay for costs from increased network traffic and maintenance work because of a surge of viewers to the U.S. firm's content, an SK spokesperson said on Friday.

The move comes after a Seoul court said Netflix should "reasonably" give something in return to the internet service provider for network usage, and multiple South Korean lawmakers have spoken out against content providers who do not pay for network usage despite generating explosive traffic.

Netflix said it will review SK Broadband's claim, and seek dialogue and explore ways in the meantime to work with SK Broadband to ensure customers are not affected.

The popularity of the hit series "Squid Game" and other offerings have underscored Netflix's status as the country's second-largest data traffic generator after Google's YouTube, but the two are the only ones to not pay network usage fees, which other content providers such as Amazon, Apple and Facebook are paying, SK said.

Netflix's data traffic handled by SK jumped 24 times from May 2018 to 1.2 trillion bits of data processed per second as of September, SK said, riding on the success of several Netflix productions from Korea including "Squid Game" and "D.P."

Wait what?

Jeff Bezos' Blue Origin: Allegations of safety issues at company

The US Federal Aviation Authority[sic][*] (FAA) has said it will review safety concerns raised by whistleblowers at Blue Origin, Amazon founder Jeff Bezos' space company.

The announcement comes after 21 current and former employees claimed the company had ignored safety concerns to gain an advantage in the space race.

Staff also complained of a culture of sexism within the company.

Blue Origin rejected the charges and said it stands by its safety record.

[...] Raising concerns over the standard of the company's flagship New Shepard rocket, which Mr Bezos travelled into space on in July, the essay writers said: "In the opinion of an engineer who has signed on to this essay, 'Blue Origin has been lucky that nothing has happened so far'."

[...] The FAA, which regulates rocket launches in the US, said that it "takes every safety allegation seriously, and the agency is reviewing the information".

In addition to the safety concerns, staff also claimed that the company's management embraces a "particular brand of sexism" under which numerous managers and senior staff displayed consistently inappropriate behaviour towards women.

[*] Federal Aviation Administration.

I'm sure the New Shepard joyride for rich people meets the same high safety standards as other amusement park rides.

https://krebsonsecurity.com/2021/10/fcc-proposal-targets-sim-swapping-port-out-fraud/

The U.S. Federal Communications Commission (FCC) is asking for feedback on new proposed rules to crack down on SIM swapping and number port-out fraud, increasingly prevalent scams in which identity thieves hijack a target's mobile phone number and use that to wrest control over the victim's online identity.

In a long-overdue notice issued Sept. 30, the FCC said it plans to move quickly on requiring the mobile companies to adopt more secure methods of authenticating customers before redirecting their phone number to a new device or carrier.

"We have received numerous complaints from consumers who have suffered significant distress, inconvenience, and financial harm as a result of SIM swapping and port-out fraud," the FCC wrote. "Because of the serious harms associated with SIM swap fraud, we believe that a speedy implementation is appropriate."

The FCC said the proposal was in response to a flood of complaints to the agency and the U.S. Federal Trade Commission (FTC) about fraudulent SIM swapping and number port-out fraud. SIM swapping happens when the fraudsters trick or bribe an employee at a mobile phone store into transferring control of a target's phone number to a device they control.

Spain: Roman Gold Coins Found by Amateur Divers Clearing Trash:

Freedivers off the coast of Spain have uncovered a treasure trove of 53 perfectly preserved gold coins from the Roman Empire, one of the largest collections ever found in Europe.

Brothers-in-law Luis Lens and César Gimeno were freediving in the Mediterranean Sea while on vacation in Xàbia, Spain. Cleaning up trash, according to The Times, as they explored the underwater scenery they came across a shiny object that resembled a "10-cent-coin," newspaper El Pais said.

After retrieving the object, they noticed an inscription with an ancient Greek or Roman face and assumed it was from jewelry.

Using the corkscrew of a Swiss Army knife, they discovered another seven coins embedded in a rock crevice.

After reporting their discovery to local authorities, a team of scuba divers and archaeologists uncovered a total of 53 gold coins, three nails, and some remains of what appeared to be a chest.

[...] "It's incredible. It's every child's dream to find a treasure," Luis Lens told El Pais.

Despite their name, neural networks are only distantly related to the sorts of things you'd find in a brain. While their organization and the way they transfer data through layers of processing may share some rough similarities to networks of actual neurons, the data and the computations performed on it would look very familiar to a standard CPU.

But neural networks aren't the only way that people have tried to take lessons from the nervous system. There's a separate discipline called neuromorphic computing that's based on approximating the behavior of individual neurons in hardware. In neuromorphic hardware, calculations are performed by lots of small units that communicate with each other through bursts of activity called spikes and adjust their behavior based on the spikes they receive from others.

On Thursday, Intel released the newest iteration of its neuromorphic hardware, called Loihi.

Louisiana's missing moon rock found in Florida thanks to broken gun:

A long-lost piece of the moon belonging to the state of Louisiana may have remained missing — if not also been discarded or destroyed — had the plaque on which it was mounted not attracted the eye of a Florida gun collector.

The man, who was looking for wood samples to use in the repair or replacement of his damaged gunstocks, purchased the Apollo 17 goodwill moon rock display without realizing what it was. The buyer, who requested to remain anonymous but resides in Merritt Island, near Cape Canaveral, said that he had likely purchased the plaque at a garage sale sometime over the past 15 years.

"I can't even tell you how long I owned it for," the man told collectSPACE.com after reaching out for information through a common contact. "I'm not even sure how much I paid for it. I buy plaques because I take the wood from the plaques and I send it over to my gunstock guy and he makes grips for my Colts and so forth."

"The wood [in the plaques] is such nice wood — that is what I buy them for," he said.

It was not until the past two years, when he was seeking a particular color wood for a repair, that he pulled the moon-rock-adorned plaque from one of the 15 to 16 boxes of plaques that he had amassed for his hobby.

"What the hell is this?" he recalled thinking after taking a good look at what was on the plaque for the first time. "Before I start stripping things off, I generally take a moment to read them."

Norwegian reservoirs power homes in Great Britain via 724km (450 mile) cable:

Norwegian reservoirs will begin powering homes in Great Britain today as the world's longest subsea power cable was switched on, in a boost to renewables and tight energy supplies this winter.

The 724-kilometre North Sea Link is the sixth of a growing network of electricity interconnectors between Great Britain and its European neighbours, to trade energy and adapt to grids increasingly reliant on the variable output of wind, solar and hydro.

First tested in June, the copper cable along the seabed of the North Sea will operate at half its potential for three months before reaching its 1400 megawatt capacity, enough to power 1.4 million homes.

Power is expected to initially mostly flow from Norway, which generates almost [all] electricity from hydro, to Great Britain, where electricity prices are higher. The link may eventually be used to export electricity from offshore windfarms for storage at pumped hydro facilities in Norway, pumping water uphill and releasing it to generate electricity when neeeded[sic].

The start of commercial operations will help Great Britain's tight margins of electricity supply this winter, which are squeezed by a fire taking out half of the capacity of a separate link to France. "It couldn't have come at a better time," says Tom Edwards at energy analysts Cornwall Insight.

CNN shut down its Facebook page in Australia after court liability ruling:

CNN shut down its Facebook page in Australia on Wednesday, after an Australian court ruled that media outlets are liable for defamatory user-generated comments.

[...] The deteriorating effects of the court's ruling on online speech in Australia serve as a warning of what's to come if U.S. lawmakers succeed in their efforts to weakening protections against such legal decisions in the United States.

[...] The court's ruling previews the grim future in store if U.S. politicians get their way and dismantle Section 230, the keystone U.S. law that shields websites from liability over user-generated content. Without it, social media platforms and any other website with user-generated content—especially those without Facebook's deep pockets—would likely die. Both Republicans and Democrats, President Joe Biden included, would like it dismantled.

Should the person doing the defaming be liable, or the owner of the page the defamation is posted on be liable?

Liquid metal encased in hydrogel makes a promising energy-harvesting device:

Scientists at North Carolina State University have developed a flexible, stretchy energy-harvesting device solely out of biocompatible soft materials: liquid metal and soft polymers known as hydrogels. It produces small amounts of electricity comparable to other energy-harvesting technologies, and it can also operate in water as well as air, according to the team's recent paper published in the journal Advanced Materials. The team thinks the new NCSU device holds promise for powering wearable devices, charging them spontaneously with no need for an external power source.

"Mechanical energy—such as the kinetic energy of wind, waves, body movement and vibrations from motors—is abundant," said co-author Michael Dickey, a chemical and bimolecular engineer at NCSU. "We have created a device that can turn this type of mechanical motion into electricity. And one of its remarkable attributes is that it works perfectly well underwater."

The NCSU scientists were particularly inspired by a 2013 paper by Korean researchers. The 2013 researchers found they could harvest energy from an electrical double-layer capacitor (ELCD) by depressing arrays of water droplets sandwiched between two rigid electrodes, thereby spontaneously charging the capacitor.

[...] The key proved to be a liquid-metal alloy of gallium and indium, per Dickey, which is then encased in a water-absorbent hydrogel. The dissolved salts in the water (ions) congregate on the metallic surface, forming an electrical double layer akin to a capacitor. Deforming the liquid metal increases the area, and the greater the surface area, the greater the induced charge.

Phone companies must now block carriers that didn’t meet FCC robocall deadline:

In a new milestone for the US government's anti-robocall efforts, phone companies are now prohibited from accepting calls from providers that did not comply with a Federal Communications Commission deadline that passed this week. "Beginning today, if a voice service provider's certification and other required information does not appear in the FCC's Robocall Mitigation Database, intermediate providers and voice service providers will be prohibited from directly accepting that provider's traffic," the FCC said yesterday.

Specifically, phone companies must block traffic from other "voice service providers that have neither certified to implementation of STIR/SHAKEN caller ID authentication standards nor filed a detailed robocall mitigation plan with the FCC." As we've written, the STIR (Secure Telephone Identity Revisited) and SHAKEN (Signature-based Handling of Asserted Information Using toKENs) protocols verify the accuracy of Caller ID by using digital certificates based on public-key cryptography.

STIR/SHAKEN is now widely deployed on IP networks because large phone companies were required to implement it by June 30 this year, but it isn't a cure-all. Because of technology limitations, there was no requirement to implement STIR/SHAKEN on older TDM-based networks used with copper landlines, for instance. The FCC has said that "providers using older forms of network technology [must] either upgrade their networks to IP or actively work to develop a caller ID authentication solution that is operational on non-IP networks."

KDE's Telemetry: The Tip Of The Iceberg?:

Recently, there was a debate on the PCLinuxOS forum about KDE Plasma's implementation of telemetry through KUserFeedback. While in PCLinuxOS, we can remove it without any collateral effects to the system, while other users reported that doing the same in other distros (like Debian 11) results in the complete removal of KDE Plasma! Why force such an implementation, if, as KDE's developers say, it is just an innocuous, privacy-respecting measure?

Coincidence or not, in the past years many popular Linux distributions started rolling out optional telemetry. Then it was the time of computer programs: news broke out in May regarding Audacity, a popular audio editing app, which announced it was starting the use of telemetry. The move was finally pushed back after users revolted against it.

While many point out that the data collection is by opt-in and entirely anonymous, others have found that, even if you don't activate telemetry, data is still collected, using computer resources, registering "apps and boot, number of times used and duration in /home/user/telemetry folder." As such, they argue that, because of the way Linux permissions work, other programs could have access to these log files. KUserFeedback's FAQs page confirms this:

"KUserFeedback is designed to be compliant with KDE Telemetry Policy, which forbids the usage of unique identification. If you are using KUserFeedback outside of the scope of that policy, it's of course possible to add a custom data source generating and transmitting a unique id."

Do any Soylentils have opinions about this, or experiences with it?
