Hiatus hacking campaign has infected roughly 100 Draytek routers:

Researchers have uncovered advanced malware that's turning business-grade routers into attacker-controlled listening posts that can sniff email and steal files in an ongoing campaign hitting North and South America and Europe.

Besides passively capturing IMAP, SMTP, and POP email, the malware also backdoors routers with a remote-access Trojan that allows the attackers to download files and run commands of their choice. The backdoor also enables attackers to funnel data from other servers through the router, turning the device into a covert proxy for concealing the true origin of malicious activity.

"This type of agent demonstrates that anyone with a router who uses the Internet can potentially be a targetand they can be used as proxy for another campaigneven if the entity that owns the router does not view themselves as an intelligence target," researchers from security firm Lumen's Black Lotus Labs wrote. "We suspect that threat actors are going to continue to utilize multiple compromised assets in conjunction with one another to avoid detection."

[...] Black Lotus still doesn't know how devices are getting hacked in the first place. Once (and however) that happens, the malware gets installed through a bash script that's deployed post-exploitation. It downloads and installs the two main binaries.

[...] Hiatus is mainly targeting DrayTek routers running an i386 architecture. The researchers, however, have uncovered prebuilt binaries compiled for ARM, MIPS64 big endian, and MIPS32 little endian platforms.

The gene-editing tool is being tested in people, and the first treatment could be approved this year:

Forget about He Jiankui, the Chinese scientist who created gene-edited babies. Instead, when you think about gene editing you should think of Victoria Gray, the African-American woman who says she's been cured of her sickle-cell disease symptoms.

[...] But the designer-baby debate is a distraction from the real story of how gene editing is changing people's lives, through treatments used on adults with serious diseases.

In fact, there are now more than 50 experimental studies underway that use gene editing in human volunteers to treat everything from cancer to HIV and blood diseases, according to a tally shared with MIT Technology Review by David Liu, a gene-editing specialist at Harvard University.

Most of these studiesabout 40 of theminvolve CRISPR, the most versatile of the gene-editing methods, which was developed only 10 years ago.

[...] To scientists, CRISPR is a revelation because of how it can snip the genome at specific locations. It's made up of a cutting protein paired with a short gene sequence that acts like GPS, zipping to a predetermined spot in a person's chromosomes.

[...] The first generation of CRISPR treatments are also limited in another way. Most use the tool to damage DNA, essentially shutting off genesa process famously described as "genome vandalism" by Harvard biologist George Church.

[...] Liu's lab is working on next-generation gene-editing approaches. These tools also employ the CRISPR protein, but it's engineered not to cut the DNA helix, but instead to deftly swap individual genetic letters or make larger edits. These are known as "base editors."

[...] Now that gene editing has had its first successes, Urnov says, there's an "urgent need" to open a "path to the clinic for all."

A large percentage of employees are dissatisfied with their experience of joining a company:

New employees who start a job feeling undertrained and disconnected from their work environment are far more likely to quit than those who have a good onboarding experience.

With the unemployment rate lower than it has been in decades  even more so in technology fields job candidates more often than not field multiple offers. So, if the onramp to a new job is bumpy, they're far more likely to reconsider staying with the organization, even in the short term.

According to research firm Gartner, 63% of new hires are satisfied with their onboarding experience. A recent survey by payroll and human resources provider Paychex showed onboarding experience affected how quickly they would quit after taking a position.

The survey of about 1,000 Americans by Paychex, released last month, found half (50%) of newly hired employeesplan to quit soon.

[...] Among the percentage of remote workers who said they're likely to leave their current job soon, 88% described their latest onboarding experience as boring, 78% called it confusing, and 74% saw it as a failure. On-site and hybrid employees fare better; only 36% of them viewed the onboarding process as confusing.

Remote workers are most likely to feel disoriented (60%) and devalued (52%) after onboarding, the survey found.

[...] Without a streamlined and supportive process, employees can be left frustrated, she said, which can muddle a new hire's first experience in a new position and affect their morale.

[...] "You need a two-way connection where they're not only learning about the company, but the company [is] learning about the employee and tailoring the onboarding experience to them. In that, they're also learning what the new hire brings to the table," Kohn said. "It works a lot better when a new hire comes in and sees a manager and a team already recognizes [that the new hire] brings strengths to the table."

There's never enough time or staff to scan code repositories:

Software dependencies, or a piece of software that an application requires to function, are notoriously difficult to manage and constitute a major software supply chain risk. If you're not aware of what's in your software supply chain, an upstream vulnerability in one of your dependencies can be fatal.

A simple React-based Web application can have upward of 1,700 transitive NodeJS "npm" dependencies, and after a few months "npm audit" will reveal that a relatively large number of those dependencies have security vulnerabilities. The case is similar for Python, Rust, and every other programming language with a package manager.

I like to think of dependencies as decaying fruit in the unrefrigerated section of the code grocer, especially npm packages, which are often written by unpaid developers who have little motivation to put in more than the bare minimum of effort. They're often written for personal use and they're open sourced by chance, not by choice. They're not written to last.

[...] Not all hope is lost. For known (reported and accepted) vulnerabilities, tools exist, such as pip-audit, which scans a developer's Python working environment for vulnerabilities. Npm-audit does the same for nodeJS packages. Similar tools exist for every major programming language and, in fact, Google recently released OSV-Scanner, which attempts to be a Swiss Army knife for software dependency vulnerabilities. Whether developers are encouraged (or forced) to run these audits regularly is beyond the scope of this analysis, as is whether they actually take action to remediate these known vulnerabilities.

However, luckily for all of us, automated CI/CD tools like Dependabot exist to make these fixes as painless as possible. These tools will continually scan your code repositories for out-of-date packages and automatically submit a pull request (PR) to fix them. Searching for "dependabot[bot]" or "renovate[bot]" on GitHub and filtering to active PRs yields millions of results! However, 3 million dependency fixes versus hundreds of millions of active PRs at any given time is an impossible quantification to attempt to make outside of an in-depth analysis.

BlackLotus represents a major milestone in the continuing evolution of UEFI bootkits:

Researchers on Wednesday announced a major cybersecurity findthe world's first-known instance of real-world malware that can hijack a computer's boot process even when Secure Boot and other advanced protections are enabled and running on fully updated versions of Windows.

Dubbed BlackLotus, the malware is what's known as a UEFI bootkit. These sophisticated pieces of malware hijack the UEFI short for Unified Extensible Firmware Interfacethe low-level and complex chain of firmware responsible for booting up virtually every modern computer. As the mechanism that bridges a PC's device firmware with its operating system, the UEFI is an OS in its own right. It's located in an SPI-connected flash storage chip soldered onto the computer motherboard, making it difficult to inspect or patch.

[...] The second thing standing in the way of UEFI attacks is UEFI Secure Boot, an industry-wide standard that uses cryptographic signatures to ensure that each piece of software used during startup is trusted by a computer's manufacturer. Secure Boot is designed to create a chain of trust that will prevent attackers from replacing the intended bootup firmware with malicious firmware. If a single firmware link in that chain isn't recognized, Secure Boot will prevent the device from starting.

While researchers have found Secure Boot vulnerabilities in the past, there has been no indication that threat actors have ever been able to bypass the protection in the 12 years it has been in existence. Until now.

[...] To defeat Secure Boot, the bootkit exploits CVE-2022-21894, a vulnerability in all supported versions of Windows that Microsoft patched in January 2022. The logic flaw, referred to as Baton Drop by the researcher who discovered it, can be exploited to remove Secure Boot functions from the boot sequence during startup. Attackers can also abuse the flaw to obtain keys for BitLocker, a Windows feature for encrypting hard drives.

https://www.science.org/content/article/ai-re-creates-what-people-see-reading-their-brain-scans

As neuroscientists struggle to demystify how the human brain converts what our eyes see into mental images, artificial intelligence (AI) has been getting better at mimicking that feat. A recent study, scheduled to be presented at an upcoming computer vision conference, demonstrates that AI can read brain scans and re-create largely realistic versions of images a person has seen. As this technology develops, researchers say, it could have numerous applications, from exploring how various animal species perceive the world to perhaps one day recording human dreams and aiding communication in people with paralysis.

Many labs have used AI to read brain scans and re-create images a subject has recently seen, such as human faces and photos of landscapes. The new study marks the first time an AI algorithm called Stable Diffusion, developed by a German group and publicly released in 2022, has been used to do this. Stable Diffusion is similar to other text-to-image "generative" AIs such as DALL-E 2 and Midjourney, which produce new images from text prompts after being trained on billions of images associated with text descriptions.

For the new study, a group in Japan added additional training to the standard Stable Diffusion system, linking additional text descriptions about thousands of photos to brain patterns elicited when those photos were observed by participants in brain scan studies.

[...] Finally, the researchers tested their system on additional brain scans from the same participants when they viewed a separate set of photos, including a toy bear, airplane, clock, and train. By comparing the brain patterns from those images with those produced by the photos in the training data set, the AI system was able to produce convincing imitations of the novel photos. (The team posted a preprint of its work in December 2022.)

"The accuracy of this new method is impressive," says Iris Groen, a neuroscientist at the University of Amsterdam who was not involved with the work.

I'm wondering how this sort of ability will effect copyright, in the long term, when it becomes possible to extract high-enough fidelity copies of media from people's brains, which they have observed before and remember. If someone views an image, listens to a song, or watches a movie, and then downloads a copy from their brain to share, is that copyright infringement? Is the copy in their head infringement? Will the law determine a percentage fidelity limit?

Seems the DHS has a secret program to spy on American citizens

For years, the Department of Homeland Security has run a virtually unknown program gathering domestic intelligence, one of many revelations in a wide-ranging tranche of internal documents reviewed by POLITICO.

Those documents also reveal that a significant number of employees in DHS's intelligence office have raised concerns that the work they are doing could be illegal.

Under the domestic-intelligence program, officials are allowed to seek interviews with just about anyone in the United States. That includes people held in immigrant detention centers, local jails, and federal prison. DHS's intelligence professionals have to say they're conducting intelligence interviews, and they have to tell the people they seek to interview that their participation is voluntary. But the fact that they're allowed to go directly to incarcerated people circumventing their lawyers raises important civil liberties concerns, according to legal experts.

That specific element of the program, which has been in place for years, was paused last year because of internal concerns. DHS's Office of Intelligence and Analysis, which runs the program, uses it to gather information about threats to the U.S., including transnational drug trafficking and organized crime. But the fact that this low-profile office is collecting intelligence by questioning people in the U.S. is virtually unknown.

IMHO, when your own employees are afraid they're breaking the law by doing their jobs; and those same people fear punishment if they speak up, says a lot about the ethics of this bullshit.

Hubble In Trouble As Satellite Trails Start Affecting It Too

The idea that we can save astronomy from satellite interference by putting telescopes in space has run into an obstacle, or more precisely 8,500.

A study of images taken by the Hubble Space Telescope finds that more than one in 40 are crossed by satellite trails. In some cases these interfere with the science, wasting the exceptionally valuable time spent taking the image. Although the affected proportion is small, it's growing, refuting the claim we can solve the problems satellites are causing for astronomers by putting the large telescopes in space.

Spotting a satellite was once rare enough to be an exciting addition to a night under the stars away from the city lights. Today, it's become an annoying impediment to enjoying the beauty of everything else. It's not only wrong to wish on space hardware, if you start you'll never do anything else.

For astronomers the problem is not just a loss of beauty. It's becoming increasingly common for satellite trails to destroy images, often ruining time precious time a scientist had to fight hard to get and holding up important research. Although this issue is getting considerable attention, a new paper in Nature Astronomy addresses an aspect that has been largely ignored.

Elon Musk, among others, has responded to concerns about satellites' effect on astronomy by saying, "We need to move telescopes to orbit anyway", but that's not necessarily a complete solution.

The Hubble Space Telescope orbits at 540 kilometers (340 miles), which is above the majority of objects humanity has put in orbit, but there are 8,460 objects more than 10 centimeters (4 inches) across above it. A team led by Dr Sandor Kruk of the Max Planck Institute for Extraterrestrial Physics recruited citizen scientists through the Hubble Asteroid Hunter project, to study Hubble's archive from 2002 to 2021 and distinguish satellite trails from asteroids.

Coastal city residents would like to do more to reduce their single-use plastic waste and they are trying to recycle more:

Coastal city residents would like to do more to reduce their single-use plastic waste and they are trying to recycle more, even trying to recycle items that simply can't be recycled, often called "wish-cycling".

But they feel unable to do so due to the current infrastructure challenges and accessibility barriers they face, a new report has found.

The study has also found that whilst young people are concerned about the use of plastic, their consumer behaviour often contradicts their beliefs.

[...] 90 per cent of people agreed it was important to recycle and 83 per cent felt that littering was a serious problem that needed addressing in Portsmouth. Results indicate that if there were more recycling options available, 79 per cent would recycle more.

However, there were obvious barriers to recycling, and people felt there was a lack of information and opportunity for recycling, with 65 per cent of people admitting they often did not know how or where to recycle plastic items.

[...] Another important finding was the impact of age on the results. The 3150 years age group were found to be more regularly shopping in Portsmouth zero-waste shops than their counterparts, while the oldest age group (over 50 years) reported being less aware and less willing to shop in these retailers. Younger respondents (less than 30 years) were more concerned about plastic waste entering the ocean than their older counterparts (over 50 years).

Roman Telescope Will Do in Months What Would Take Hubble a Lifetime:

NASA is still a few years away from launching the Nancy Grace Roman Space Telescope, but a new study explores what this groundbreaking space observatory will be able to do. Unlike the Hubble and James Webb space telescopes, which zero in on small patches of the sky, the Roman Telescope will be designed to take a wider view of the cosmos. According to the researchers, it would take Hubble decades to see what Roman will be able to see in a few months.

The Roman Telescope passed a critical design review in 2021 and is currently under construction at NASA's Goddard Space Flight Center with the aim of launching it aboard a SpaceX Falcon Heavy rocket in 2027. When complete, it will have two instruments: a coronagraph for visualizing exoplanets and a wide-field camera with a 300.8-megapixel resolution. It's the latter that will allow the Roman Telescope, which will use a 2.4-meter mirror similar to Hubble, to perform both wide and deep sky surveys.

[...] "Roman will take around 100,000 pictures every year," said Jeffrey Kruk, a research astrophysicist at Goddard. "Given Roman's larger field of view, it would take longer than our lifetimes even for powerful telescopes like Hubble or Webb to cover as much sky." Specifically, the study says it would take Hubble 85 years to do what Roman will do in 63 days. However, Roman won't be ideal for precision observations of specific objects. Webb and Hubble will still be vital for that kind of work, but Roman can help nail down observational targets that could solve long-standing mysteries about galactic evolution.

AstroAccess is on a mission to make it possible for disabled people to live and work in space:

"I went silent," Dwayne Fernandes told me. "I shut the hell up." Fernandes, a double-amputee since the age of 11, was recounting his experience in weightlessness, having recently participated in a parabolic flight alongside a disabled research crew. The zero-g flight threw him into a deeply contemplative state, and as the crew celebrated its successful mission, he instead felt compelled to put pen to paper and write some poetry.

Speaking to me from his home in Australia, Fernandes told me that "disability is not just a wheelchairwe need to expand that thinking." Disability, he said, is "a condition plus barriers," which for wheelchair users includes barriers such as height or stairs. But gravity can also be a barrier, as he pointed out.

"On that zero-g flight, I had my conditionthe condition stayedbut the barrier went," Fernandes explained. "That became a profound, weird feeling that caused me to re-identify myself. The social model of disability says I'm a person with a disability, but my condition changed in a zero-g environment." When in weightlessness, "I am not disabledI am actually super enabled."

Elaborating on this point, Fernandes described himself as being "compact" and with "upgradeable parts." Legs "get in the way in space," he said, and, as extra weight, they only serve to increase launch costs. "There's no such thing as a spacewalk," he said. "Your feet aren't walkingyour feet are just anchored." All he would need to live and work in space, he said, are "a couple of carabiners and some hooks."

Iberians were using heavy metal on hard rock way before it was cool:

It's time to update the history books again. A group of researchers in Germany have shown that steel tools were being used in the Iberian peninsula at least as long ago as 900 BCE far earlier than it was believed knowledge of the metal had made its way to the region.

The team, led by University of Freiburg archaeologist Ralph Araque Gonzalez, base their claims on geochemical and metallographic analyses and some good old fashioned experimental archaeology. They demonstrated that a series of engravings on stone pillars found in the region from the late Bronze Age could only have been made with tools made from proper steel, and it was most likely developed locally.

According to the team's paper on the research, the final bronze age (FBA) in the Iberian peninsula lasted from around 1200800 BCE, and the early iron age (EIA) lasted roughly 200 years after that. Despite that commonly accepted timeline, the team said a series of engraved steles identified as from the FBA/EIA and examined as part of the study were mostly made of extremely hard rock similar to quartzite.

[...] According to the University of Freiburg, up until recently it was believed the ability to create steel an alloy of iron and carbon only became widespread in Europe with the expansion of the Roman Empire.

[...] But evidence of steel tools in Iberia hundreds of years earlier raises a question: how did they get there? Based on where the tool was found, and the context in which it was discovered, Araque Gonzalez concluded that the Romans probably had nothing to do with it.

[...] "Iron metallurgy including the production and tempering of steel were probably indigenous developments of decentralized small communities in Iberia, and not due to the influence of later colonization processes," Araque Gonzalez hypothesized.

'Firemode reset' sees Interstellar Boundary Explorer back on the job:

NASA engineers have managed to restore the Interstellar Boundary Explorer spacecraft to working condition by using the oldest trick in the computing book.

IBEX was put into contingency mode in February after NASA reset its onboard systems and the almost 15-year-old spacecraft's flight computer subsequently failed to respond to commands uploaded from mission control. Engineers have since performed a so-called "firecode reset" as the craft's orbit reached its closest point to Earth.

"To take the spacecraft out of a contingency mode, the mission team performed a firecode reset (which is an external reset of the spacecraft) instead of waiting for the spacecraft to perform an autonomous reset and power cycle on March 4," NASA confirmed on Monday.

"After the firecode reset, command capability was restored. IBEX telemetry shows that the spacecraft is fully operational and functioning normally."

Launched in 2008, the IBEX spacecraft carries instruments to detect energetic neutral atoms (ENAs) that form when hot ions from the solar wind collide with cold gaseous atoms from the interstellar medium, the stuff in-between stars in outer space.

Using data collected from the IBEX-Hi and IBEX-Lo sensors, astronomers can plot the boundaries of the Solar System. All the planets and other astronomical objects are encased in a bubble known as the "heliosphere" created by the solar wind.

[...] Fixing the satellite will allow astronomers to continue gathering data on the Sun's activity and solar wind for a while yet.

An electric humming vibrator designed to upset neighbors operated for about a month inside New Zealand's tallest apartment tower, sending 25 neighbors "just about insane" before it was discovered and disabled, a resident says.

Once praised for its generous social safety net, the country now collects troves of data on welfare claimants:

Denmark's Public Benefits Administration employs hundreds of people who oversee one of the world's most well-funded welfare states. The country spends 26 percent of its GDP on benefitsmore than Sweden, the United States, and the United Kingdom. It's been hailed as a leading example of how governments can support their most vulnerable citizens. Bernie Sanders, the US senator, called the Nordic nation of 6 million people a model for how countries should approach welfare.

But over the past decade, the scale of Denmark's benefits spending has come under intense scrutiny, and the perceived scourge of welfare fraud is now at the top of the country's political agenda. Armed with questionable data on the amount of benefits fraud taking place, conservative politicians have turned Denmark's famed safety net into a polarizing political battleground.

It has become an article of faith among the country's right-wing politicians that Denmark is losing hundreds of millions of euros to benefits fraud each year. In 2011, KMD, one of Denmark's largest IT companies, estimated that up to 5 percent of all welfare payments in the country were fraudulent. KMD's estimates would make the Nordic nation an outlier, and its findings have been criticized by some academics. In France, it's estimated that fraud amounts to 0.39 percent of all benefits paid. A similar estimate made in the Netherlands in 2016 by broadcaster RTL found the average amount of fraud per benefit payment was 17 ($18), or just 0.2 percent of total benefits payments.The perception of widespread welfare fraud has empowered Jacobsen to establish one of the most sophisticated and far-reaching fraud detection systems in the world.

The total value of these imports also declined, from $68.8 billion last year to $47.8 billion, a drop of 30.5%. That's partly due to chip prices that have fallen due to oversupply and the general economic downturn.

China's IC exports also fell in the first two months, down 20.9% to 37.3 billion units, while the total value of the exports dropped 25.8%.

The US has been tightening its restrictions on China's chip industry over the last 12 months, which the United States says will prevent its global rival from developing semiconductors for military applications, including supercomputers, nuclear weapons modeling, and hypersonic weapons.

October's restrictions on chipmaking tools from the Bureau of Industry and Security were some of the harshest, designed to cap China's logic chips at the 14-nanometre node, DRAM at 18nm, and 3D NAND flash at 128 layers.

After Nearly a Decade in Development, Japan's New Rocket Fails in Debut

upstart writes:

Japan's science minister said the failure was "extremely regrettable:

The launch of Japan's H3 rocket on Tuesday morning failed after the vehicle's second stage engine did not ignite.

In a terse statement on the failure, Japanese space agency JAXA said, "A destruct command has been transmitted to H3 around 10:52 a.m. (Japan Standard Time), because there was no possibility of achieving the mission. We are confirming the situation."

The Japanese space agency, in concert with the rocket's manufacturer, Mitsubishi Heavy Industries, has spent about $1.5 billion developing the H3 rocket over the last decade. Much of the challenge in building the new rocket involved development of a new LE-9 engine, which is fueled by liquid hydrogen and liquid oxygen, to power the first stage. This appeared to perform flawlessly. The second-stage engine that failed, the LE-5B, was a more established engine.

The country has sought to increase its share of the commercial launch market by building a lower-cost alternative to its older H2-A vehicle to more effectively compete with SpaceX's Falcon 9 booster. Mitsubishi's goal was to sell the H3 at $51 million per launch in its base configuration. This would allow the company to supplement its launches of institutional missions for the Japanese government with commercial satellites. Tuesday's debut flight of the H3 rocket carried the Advanced Land Observing Satellite-3 for the Japanese government. It was lost.

[...] The failure is just the latest challenge for the H3 rocket. A fundamental problem with the booster is that, even if it were to fly safely, the H3 rocket has no clear advantages over the Falcon 9, which now has a streak of more than 170 consecutive successful launches. The new H3 rocket is also fully expendable, unlike the Falcon 9 and many newer boosters in development in the United States and China.

The health department had always said it was approaching the problem cautiously, working to keep a "balance between restricting somebody's liberty and protecting the health of the community." It sees detention as the "very, very last option."

50 Years Later, We're Still Living in the Xerox Alto's World:

[...] I'm talking about the Xerox Alto, which debuted in the early spring of 1973 at the photocopying giant's newly established R&D laboratory, the Palo Alto Research Center (PARC). The reason it is so uncannily familiar today is simple: We are now living in a world of computing that the Alto created.

The Alto was a wild departure from the computers that preceded it. It was built to tuck under a desk, with its monitor, keyboard, and mouse on top. It was totally interactive, responding directly to its single user.

[...] The people who developed the Alto came to Xerox PARC from universities, industrial labs, and commercial ventures, bringing with them diverse experiences and skills. But these engineers and programmers largely shared the same point of view. They conceived and developed the Alto in a remarkable burst of creativity, used it to develop diverse and pathbreaking software, and then moved out of Xerox, taking their achievements, design knowledge, and experiences into the wider world, where they and others built on the foundation they had established.

[...] The type of computing they envisioned was thoroughly interactive and personal, comprehensively networked, and completely graphicalwith high-resolution screens and high-quality print output.

[...] Oddly, at the time, an expensive new laboratory was also immediately financially attractive: R&D expenditures were frequently counted as assets instead of business expenses, all with Wall Street's approval. The more you spent, the better your balance sheet looked.

Dutch Officials Warn That Big Telecom's Plan To Tax 'Big Tech' Is A Dangerous Dud:

For much of the last year, European telecom giants have been pushing for a tax on Big Tech company profits. They've tried desperately to dress it up as a reasonable adult policy proposal, but it's effectively just the same thing we saw during the U.S. net neutrality wars: telecom monopolies demanding other people pay them an additional troll toll for no coherent reason.

To sell captured lawmakers on the idea, telecom giants have falsely claimed that Big Tech companies get a "free ride" on the Internet (just as they did during the U.S. net neutrality wars). To fix this problem they completely made up, Big Telecom argues Big Tech should be forced to help pay for the kind of broadband infrastructure upgrades the telecoms have routinely neglected for years.

It's a big, dumb con. But yet again, telecom lobbyists have somehow convinced regulators that this blind cash grab is somehow sensible, adult policy. Dutifully, European Commission's industry chief Thierry Breton (himself a former telecom exec) said last September he would launch a consultation on this "fair share" payment scheme in early 2023, ahead of any proposed legislation.

[...] But they're often not looking at the real problem. Both in the EU and North America, regulators routinely and mindlessly let telecom giants consolidate and monopolize an essential utility. Those monopolies then work tirelessly to drive up rates and crush competition. And, utilizing their lobbying power, they've also routinely gleamed billions in subsidies for networks they routinely half-complete.

[...] If the EU successfully implements such a scheme, you can be absolutely sure the next step will be the U.S., with captured regulators like Brendan Carr (who has been beating this idiotic drum for a few years now) at the front of the parade at Comcast's and AT&T's behest.

https://www.righto.com/2023/02/8086-modrm-addressing.html

One interesting aspect of a computer's instruction set is its addressing modes, how the computer determines the address for a memory access. The Intel 8086 (1978) used the ModR/M byte, a special byte following the opcode, to select the addressing mode.1 The ModR/M byte has persisted into the modern x86 architecture, so it's interesting to look at its roots and original implementation.

In this post, I look at the hardware and microcode in the 8086 that implements ModR/M2 and how the 8086 designers fit multiple addressing modes into the 8086's limited microcode ROM. One technique was a hybrid approach that combined generic microcode with hardware logic that filled in the details for a particular instruction. A second technique was modular microcode, with subroutines for various parts of the task.

I've been reverse-engineering the 8086 starting with the silicon die. The die photo below shows the chip under a microscope. The metal layer on top of the chip is visible, with the silicon and polysilicon mostly hidden underneath. Around the edges of the die, bond wires connect pads to the chip's 40 external pins. I've labeled the key functional blocks; the ones that are important to this discussion are darker and will be discussed in detail below. Architecturally, the chip is partitioned into a Bus Interface Unit (BIU) at the top and an Execution Unit (EU) below. The BIU handles bus and memory activity as well as instruction prefetching, while the Execution Unit (EU) executes instructions and microcode. Both units play important roles in memory addressing.

The corridor is 30 feet long and likely slopes upward. Where it leads is still a mystery.

In 2016, scientists using muon imaging picked up signals indicating a hidden corridor behind the famous chevron blocks on the north face of the Great Pyramid of Giza in Egypt. The following year, the same team detected a mysterious void in another area of the pyramid, believing it could be a hidden chamber. Two independent teams of researchers, using two different muon imaging methods, have now successfully mapped out the corridor for the first time, according to a new paper published in the journal Nature Communications. Zahi Hawass, Egypt's former antiquities minister, called it "the most important discovery of the 21st century." [So far - Ed]

As we've reported previously, there is a long history of using muons to image archaeological structures, a process made easier because cosmic rays provide a steady supply of these particles. An engineer named E.P. George used them to make measurements of an Australian tunnel in the 1950s. But Nobel-prize-winning physicist Luis Alvarez really put muon imaging on the map when he teamed up with Egyptian archaeologists to use the technique to search for hidden chambers in the Pyramid of Khafre at Giza. Although it worked in principle, they didn't find any hidden chambers.

There are many variations of muon imaging, but they all typically involve gas-filled chambers. As muons zip through the gas, they collide with the gas particles and emit a telltale flash of light, which is recorded by the detector, allowing scientists to calculate the particle's energy and trajectory. It's similar to X-ray imaging or ground-penetrating radar, except with naturally occurring high-energy muons rather than X-rays or radio waves. That higher energy makes it possible to image thick, dense substances like the stones used to build pyramids. The denser the imaged object, the more muons are blocked, casting a telltale shadow. Hidden chambers in a pyramid would show up in the final image because they blocked fewer particles.

Huge lithium find may end world shortage there's a catch:

Lithium, sometimes hyped as white gold, has been highly sought after for its role in battery production, and other things.

Global demand is expected to continue to outstrip supply in the years to come. Albemarle Corporation projects [PDF] lithium demand will rise from 1.8 million metric tons in 2025 to 3.7 million metric tons in 2030 largely due to its role in electric vehicles and other battery dependent devices.

The White House last year said critical minerals rare earth metals, lithium, and cobalt "are essential to our national security and economic prosperity."

Alas for the US, the latest cache of this malleable metal has turned up in Iran one of just four countries America has designated a state sponsor of terrorism.

According to The Financial Tribune, an English language news publication focused on Iran that's operated by Tehran-based Donya-e-Eqtesad, Ebrahim Ali Molla-Beigi, director general of the Exploration Affairs Office of the Ministry of Industries, Mining and Trade, said that Iran has discovered its first lithium reserve in Hamedan Province, in the western part of the country.

The reserve is said to be 8.5 million metric tons, which if accurate would be among the largest known deposits yet discovered.

According to the US Geological Survey [PDF], the top five identified lithium reserves are: Bolivia, 21 million tons; Argentina, 20 million tons; Chile, 11 million tons; Australia, 7.9 million tons, and China, 6.8 million tons.
