Mozilla developers are putting the finishing touches on a new feature that will block insecure file downloads in Firefox.

Called mixed content downloaded blocking, the feature works by blocking files downloads initiated from an encrypted HTTPS page but which actually take place via an unencrypted HTTP channel.

The idea behind this feature is to prevent Firefox users from getting misled by the URL bar and think they're downloading a file securely via HTTPS when, in reality, the file could be tampered with by third parties while in transit.

GM to spend $1 billion to expand Chevy Bolt EV recall due to fires:

GM said it is pursuing reimbursement commitments from EV battery supplier LG Energy Solution, which produced the defective parts in plants in South Korea and Michigan. Parts from the U.S. plant were previously not involved in the recall.

The automaker plans to replace the vehicle's costly battery cell modules. GM also said it is working with LG to rectify the cause of the defects and increase production of the new modules.

"Our focus on safety and doing the right thing for our customers guides every decision we make at GM," Doug Parks, a GM executive vice president who oversees products, purchasing and supply chains, said in a release. "As leaders in the transition to an all-electric future, we know that building and maintaining trust is critical. GM customers can be confident in our commitment to taking the steps to ensure the safety of these vehicles."

The expansion follows the companies finding that the batteries for these vehicles may have two manufacturing defects — a torn anode tab and folded separator — present in the same battery cell, which increases the risk of fire.

Under the northern lights: Mesospheric ozone layer depletion explained:

The same phenomenon that causes aurorae -- the magical curtains of green light often visible from the polar regions of the Earth -- causes mesospheric ozone layer depletion. This depletion could have significance for global climate change and therefore, understanding this phenomenon is important.

[...] In the Earth's magnetosphere -- the region of magnetic field around the Earth -- electrons from the sun remain trapped. Interactions between electrons and plasma waves can cause the trapped electrons to escape and enter the Earth's upper atmosphere (thermosphere). This phenomenon, called electron precipitation, is responsible for aurorae. But, recent studies show that this is also responsible for local ozone layer depletions in the mesosphere (lower than thermosphere) and may have a certain impact on our climate.

What's more, this ozone depletion at the mesosphere could be occurring specifically during aurorae. And while scientists have studied electron precipitation in relation to aurorae, none have been able to sufficiently elucidate how it causes mesospheric ozone depletion.

Prof. Miyoshi and team took the opportunity to change this narrative during a moderate geomagnetic storm over the Scandinavian Peninsula in 2017. They aimed their observations at "pulsating aurorae" (PsA), a type of faint aurora. Their observations were possible through coordinated experiments with the European Incoherent Scatter (EISCAT) radar (at an altitude between 60 and 120 km where the PsA occurs), the Japanese spacecraft Arase, and the all-sky camera network.

Arase data showed that the trapped electrons in the Earth's magnetosphere have a wide energy range. It also indicated the presence of chorus waves, a type of electromagnetic plasma wave, in that region of space. Computer simulations then showed that Arase had observed plasma waves causing precipitations of these electrons across the wide energy range, which is consistent with EISCAT observations down in the Earth's thermosphere.

Stradivari and Guarneri Treated Soundboards With Various Chemicals, Study Shows

Stradivari and Guarneri Treated Soundboards with Various Chemicals, Study Shows:

Two renowned violin makers from Cremona, Italy, Antonio Stradivari and Giuseppe Guarneri 'del Gesù,' treated their instruments with various chemicals that produced their unique sound, and several of these chemicals have been identified for the first time: borax and metal sulfates for fungal suppression, table salt for moisture control, alum for molecular crosslinking, and potash or quicklime for alkaline treatment.

In string instruments, specially selected woods act as transducers of mechanical energy from vibrating strings into acoustic energy.

Violin-family instruments, including violas and cellos, are made of two types of tonewoods: Norway spruce (Picea abies) for soundboards and maple (Acer sp.) for ribs and back plates.

Curiously, leading violinists today still prefer antique instruments made by Antonio Stradivari and Giuseppe Guarneri 'del Gesù.'

Stradivari made about 1,200 violins in his lifetime and sold them only to the very rich, including the royalty. Today, there are about 600 Stradivari violins remaining. He also made violas and cellos that are highly prized.

Guarneri 'del Gesù' had trouble selling his work, but his instruments are now considered equal in quality and price to Stradivari violins.

[...] "All of my research over many years has been based on the assumption that the wood of the great masters underwent an aggressive chemical treatment, and this had a direct role in creating the great sound of the Stradivari and the Guarneri," said Professor Joseph Nagyvary, a researcher in the Department of Biochemistry and Biophysics at Texas A&M University.

[...] "Both Stradivari and Guarneri would have wanted to treat their violins to prevent worms from eating away the wood because worm infestations were very widespread at that time."

[...] "This new study reveals that Stradivari and Guarneri had their own individual proprietary method of wood processing, to which they could have attributed a considerable significance," Professor Nagyvary said.

The Secret of the Stradivari Violin Confirmed

The secret of the Stradivari violin confirmed:

[Professor Joseph Nagyvary] said that the varnish recipes were not secret because the varnish itself is not a critical determinant of tone quality. In contrast, the process of how the fresh spruce planks were treated and processed with a variety of water-based chemical treatments is critical for the sound of the finished violin.

Such knowledge was needed to gain a "competitive advantage" over other instrument makers, he said.

Nagyvary added that the team found the chemicals used were found all over and inside the wood, not just its surface, and this directly affected the sound quality of the instruments.

He said that further research is need to clarify other details of how the chemicals and wood produced pristine tonal quality.

"First, one needs several dozens of samples from not only Stradivari and Guarneri, but also from other makers of the Golden Period (1660-1750) of Cremona, Italy," he said. "There will have to be better cooperation between the master restorers of antique musical instruments, the best makers of our time, and the scientists who are performing the experiments often pro bono in their free time."

Nagyvary has been involved with violin research much of his 87 years. He first learned to play in Switzerland on an instrument that once belonged to Albert Einstein.

SpaceX Now Claims They Might Return Humans to the Moon Even Before 2024

SpaceX Now Claims They Might Return Humans to The Moon Even Before 2024:

It's no secret that a new Space Race has been brewing over the past few years. This time, rather than being a competition between two federal space agencies, the race has more competitors and is more complicated.

In addition to more state competitors, there are also commercial space entities vying for positions and lucrative contracts. Add to that a network of public-private partnerships, and you have Space Race 2.0!

In particular, there has been quite the stir ever since NASA awarded the Artemis contract for the Human Landing System (HLS) to SpaceX. This resulted in legal challenges filed by Blue Origin and Dynetics (SpaceX's competitors), as well as a lawsuit and messy public relations campaign.

NASA has since removed the stop-work order and commenced payments to SpaceX, which recently indicated their HLS concept could be ready to go before the 2024 deadline.

As part of the NextSTEP – 2 Appendix H program, NASA selected SpaceX, Blue Origin, and Dynetics to develop the HLS that will take the Artemis III astronauts back to the lunar surface. Initially, NASA hoped to award contracts to two of these companies but ultimately went with SpaceX due to budget constraints and timetables.

In response, Blue Origin and Dynetics filed a protest with the Government Accountability Office (GAO).

SpaceX Thinks It Can Send Humans to the Moon Sooner Than 2024 - Universe Today

SpaceX Thinks it can Send Humans to the Moon Sooner Than 2024 - Universe Today adds:

The SpaceX HLS concept is a modified version of the Starship, which is currently undergoing rapid development (along with the Super Heavy booster) at SpaceX's launch facility near Boca Chica. According to the latest mockup (shown above) and previous statements by Musk, the HLS Starship will have a higher payload capacity since it will not require heat shields, flaps, and large gas thruster packs (all of which are needed for atmospheric reentry).

It also comes with wider landing legs, which future Starships may do away with entirely now that SpaceX is building the "Mechazilla" launch tower. In any case, concerns about potential delays and fulfilling the 2024 deadline go beyond the four months lost due to the GAO's stop order. In addition, there are reported issues with the Exploration Extravehicular Mobility Units (xEMU) spacesuits, leading to fears that they won't be ready in time.

At least 22 dead after 17 inches of rain in Tennessee:

Up to 17 inches [(43 cm)] of rain fell in Humphreys County in less than 24 hours Saturday, appearing to shatter the Tennessee record for one-day rainfall by more than 3 inches, the National Weather Service said.

[...] At the beginning of a news conference on Tropical Storm Henri’s impact on New England, President Joe Biden offered condolences to the people of Tennessee and directed federal disaster officials to talk with the governor and offer assistance.

[...] A flash flood watch was issued for the area before the rain started, with forecasters saying 4 to 6 inches of rain was possible. The worst storm recorded in this area of Middle Tennessee only dropped 9 inches of rain, said Krissy Hurley, a weather service meteorologist in Nashville.

“Forecasting almost a record is something we don’t do very often,” Hurley said. “Double the amount we’ve ever seen was almost unfathomable.”

Recent scientific research has determined that extreme rain events will become more frequent because of man-made climate change. Hurley said it is impossible to know its exact role in Saturday’s flood, but noted in the past year her office dealt with floods that used to be expected maybe once every 100 years in September south of Nashville and in March closer to the city.

Best Way to Make Tea - Kettle or Microwave?:

Because you're typically heating a liquid from beneath, like setting a kettle over a stovetop, the liquid at the bottom of the container warms up, becomes less dense, and floats to the top. At the same time, the cooler liquid at the top starts to sink closer to the heat source. Eventually, you get a uniform temperature throughout.

But microwaves are an entirely different beast. A magnetron inside the metal box generates microwaves, the kind of electromagnetic radiation that gives the appliance its name. Microwaves fall along the electromagnetic spectrum, just like the ultraviolet light you protect your skin from in the summer, or the X-ray scans your doctor might take.

From there, the magnetron converts electricity from your home into some pretty intense radio waves. A channel called a "wave guide" blasts the radiation into the microwave box to heat your meal or, in this case, water. A turntable rotates the food in question to evenly heat it.

The microwaves bounce all over the reflective metal walls until they ping your food or drink. Then, they blast right through the food, just like radio waves can travel through the walls in your home. This excites the molecules inside the food, causing them to vibrate more quickly, creating heat.

Because the electromagnetic waves are coming from all angles of the microwave unit, rather than just from the bottom, convection doesn't occur at all. Instead, the liquid at the top is much hotter than the liquid at the bottom, which isn't optimal for the seasoned tea connoisseur.

Razer bug lets you become a Windows 10 admin by plugging in a mouse:

A Razer Synapse zero-day vulnerability has been disclosed on Twitter, allowing you to gain Windows admin privileges on a local computer simply by plugging in a mouse.

[...] When plugging in a Razer device into Windows 10 or Windows 11, the operating system will automatically download and begin installing the Razer Synapse software on the computer. Razer Synapse is software that allows users to configure their hardware devices, set up macros, or map buttons.

Security researcher jonhat discovered a zero-day vulnerability in the plug-and-play Razer Synapse installation that allows users to gain SYSTEM privileges on a Windows device quickly.

[...] When we plugged the Razer device into Windows 10, the operating system automatically downloaded and installed the driver and the Razer Synapse software.

Since the RazerInstaller.exe executable was launched via a Windows process running with SYSTEM privileges, the Razer installation program also gained SYSTEM privileges

[...] When the Razer Synapse software is installed, the setup wizard allows you to specify the folder where you wish to install it. The ability to select your installation folder is where everything goes wrong.

When you change the location of your folder, a 'Choose a Folder' dialog will appear. If you press Shift and right-click on the dialog, you will be prompted to open 'Open PowerShell window here,' which will open a PowerShell prompt in the folder

]...] As this PowerShell prompt is being launched by a process with SYSTEM privileges, the PowerShell prompt will also inherit those same privileges.

National Ignition Facility Breakthrough: Experiment Puts Researchers at Threshold of Fusion Ignition:

On August 8, 2021, an experiment at Lawrence Livermore National Laboratory's (LLNL's) National Ignition Facility (NIF) made a significant step toward ignition, achieving a yield of more than 1.3 megajoules (MJ). This advancement puts researchers at the threshold of fusion ignition, an important goal of the NIF, and opens access to a new experimental regime.

The experiment was enabled by focusing laser light from NIF — the size of three football fields — onto a target the size of a BB that produces a hot-spot the diameter of a human hair, generating more than 10 quadrillion watts of fusion power for 100 trillionths of a second.

"These extraordinary results from NIF advance the science that NNSA depends on to modernize our nuclear weapons and production as well as open new avenues of research," said Jill Hruby, DOE under secretary for Nuclear Security and NNSA administrator.

[...] "This result is a historic step forward for inertial confinement fusion research, opening a fundamentally new regime for exploration and the advancement of our critical national security missions. It is also a testament to the innovation, ingenuity, commitment and grit of this team and the many researchers in this field over the decades who have steadfastly pursued this goal," said LLNL Director Kim Budil. "For me it demonstrates one of the most important roles of the national labs – our relentless commitment to tackling the biggest and most important scientific grand challenges and finding solutions where others might be dissuaded by the obstacles."

Cancer patients' own cells used in 3D printed tumours to test treatments:

TEL AVIV, Aug 18 (Reuters) - Researchers have used brain cancer patients' own cells in a form of 3D printing material to make a model of their tumour to test the efficacy of potential treatments before using them for real inside the body.

The scientists extract "a chunk" of the tumour from the brain of a patient with glioblastoma [...] and use it to print a model matching their MRI scans, said Professor Ronit Satchi-Fainaro, who led the research at Tel Aviv University.

The patient's blood is then pumped through the printed tumour, made with a compound that mimics the brain, followed by a drug or therapeutic treatment.

While previous research has used such "bioprinting" to simulate cancer environments, the Tel Aviv University researchers say they are the first to print a "viable" tumour.

[...] A treatment is deemed promising if the printed tumour shrinks or if it lowers metabolic activity against control groups.

The article has photos and a short video of the process.

[Update #2; 2021-08-23 02:35:27 UTC]

So, mechanicjay responded to the bat signal, and "did a kill on every process that referenced slashd and started the service."

We think that should do the trick; please reply here or in the #soylent channel on IRC.

Again, many MANY thanks for your patience and understanding!

[Update #1; 2021-08-23 01:41:16 UTC]

"Constants aren't; variables won't." So goes an old adage. Seems to be the case for us, as well. My efforts to get comment counts to update and to get get mod points to be distributed have been fruitless. I've reached out to mechanicjay to see if he is available to take a look and lend a hand. So far, it appears that mod points were not distributed at 00:10 UTC this [Monday] morning.

I apologize for the disruption. --martyb

Original story follows below the fold.

As if nothing else of importance was going on with the site pertaining to moderation...

We discovered this morning that slashd (think slashdot's creation of cron way back in slashdot's early days) did not run to completion overnight. And, obviously, it chose to die right when it was handing out mod points for the day.

(NB: Rehash (the code that runs the site) is a fork of a version of slashcode. That code was open-sourced a couple years before we grabbed it. It also needed a great deal of work to get into an actually-functioning state.)

It actually handed out some mod points. It wasn't until we received reports that some people failed to get mod points that we realized there was a problem. I restarted slashd. Problem solved, right?

That would be easy. Who wants easy on a Sunday? Apparently easy was not in the cards for today.

We later learned that things were left in an interim state — some users got some mod points and others did not get any. Of course, I did not realize *that* until a bunch of people had used mod points.

So there was no obvious way to give "make up" mod points to those who missed out. (My mysql skills are limited.) Nor, apparently, was it obvious to any other staff who was around.

Rather than mung (Mung Until No Good) things even further, in discussion with other staff, it was decided to leave well enough alone. Things should clear themselves up on their own the next time mod points are scheduled to be re-issued (starting each morning at 00:10 UTC).

Tesla unveils chip to train A.I. models inside its data centers:

Tesla on Thursday unveiled a custom chip for training artificial-intelligence networks in data centers.

The work, shown at the automaker's live-streamed AI Day, demonstrates the company's continuing pursuit of vertical integration.

The D1 chip, part of Tesla's Dojo supercomputer system, uses a 7-nanometer manufacturing process, with 362 teraflops of processing power, said Ganesh Venkataramanan, senior director of Autopilot hardware. Tesla places 25 of these chips onto a single "training tile," and 120 of these tiles come together across several server cabinets, amounting to over an exaflop of power, Venkataramanan said.

"We are assembling our first cabinets pretty soon," said Venkataramanan, who previously worked at chipmaker AMD.

He said the Tesla technology will be the fastest AI-training computer.

[...] "We should have Dojo operational next year," CEO Elon Musk said.

I'd like some feedback from those on Soylent News about a personal project of mine -- a "unique" Git glossary. (After looking at a few terms, it should be clear what makes it unique from other Git glossaries.)

For those who use Git, it's pretty well known that Git documentation is... how shall I put this nicely? Git documentation is "difficult to understand" at times.

I never learned Git from more experienced people at the places I worked, because the groups in which I worked never used Git. That means I started learning Git on my own at home. This turned into a confusing and frustrating experience because as I tried to learn Git from different online sources and even a couple of books, I noticed a lot of conflicting information. No one seemed to be able to agree what terms to use or what certain terms meant. Turning to more official sources, it didn't get any better. Actually, sometimes it was worse.

I decided to figure out what exact Git terminology is and where things went wrong -- my glossary was born. My glossary is not meant to replace the Git documentation in any way, but to supplement it.

Pulling information from the official Git glossary, man pages, and Pro Git (the book distributed by the Git website for beginners), I realized some things that I'd never seen written down anywhere else. For instance, the term remote reference has two differing definitions, branch has five definitions, and in my detailed version of the definition of tag, I explain that I could never find any clear definition of tag.

The terms remote and tracking were the most challenging. They were so poorly defined and so poorly documented by Git that not only do they have glossary entries, but I wrote complete and highly detailed articles about them. (Links to the articles can be found in the glossary entries.)

Here are my two main links:

  • Glossary -- This is the beginning of the glossary. Under the table of contents, you can pick the term you want. Some terms have a link for "More Details" that goes into more detail about the chosen term.
  • Introduction -- This index.html file gives a link to the glossary plus the four articles that I wrote about Git terminology. It also states my target audience, where I pull most of my information from, which creative common license I use, and one or two other things.

I'd like your feedback: if you know Git well, I'd like to know if I've gone completely off the rails. If you're a casual user of Git, I'd like to know if the glossary is helpful or confusing.

Expect a few rough spots, though. The glossary is still a work in progress. There are typos, terminology that I should probably add (suggestions are welcome), and a few things that are "half baked" (although I think you'll recognize them when you see them). Nevertheless, there should be plenty enough to get a feel for what I'm trying to do.

One other thing that might interest you: The entire thing is written in html and css. There is no javascript. That means no tracking, and the files are small for the large amount of info given.
