contact@hardwareand.co (David S.)

Le 13 avril 2023, la NVIDIA GeForce RTX 4070 était officiellement lancée et d'ailleurs testée sur H&Co, alors que le site était encore tout jeune. Mais, comme toujours, ce lancement a été précédé de nombreux mois de rumeurs et autres fuites. Si on remonte à mi-2022 par exemple, il était courant...

'Eno' Documentary: Different at Every Screening, to Explore Randomness and 'Generative' Film-making

✇Slashdot
EditorDavid
From The New York Times: The key to "Eno" comes near the beginning of the film — at least, the beginning of the first version I saw. The musician Brian Eno, the documentary's subject, notes that the fun of the kind of art he makes is that it's a two-way street. "The audience's brain does the cooking and keeps seeing relationships," he says. Most movies are made up of juxtapositions of scenes, carefully selected and designed by the editor. But "Eno," directed by Gary Hustwit, turns that convention on its head. Writ large, it's a meditation on creativity. But every version of the movie you see is different, generated by a set of rules that dictate some things about the film, while leaving others to chance. (I've seen it twice, and maybe half the same material appeared across both films.) Eno, one of the most innovative and celebrated musicians and producers of his generation, has fiddled with randomness in his musical practice for decades, often propelled along by new technologies. He agreed to participate in "Eno" only if it, too, could be an example of what he and others have long called generative art... "Brain One", programmed by the artist Brendan Dawes, generates a new version of the film on the fly every time the algorithm is run. Dawes's system selects from a database of 30 hours of new interviews with Eno and 500 hours of film from his personal archive and, following a system of rules set down by the filmmakers with code, creating a new film. According to the filmmakers, there are 52 quintillion (that is, 52 billion billion) possible combinations, which means the chances of Brain One generating two exact copies of "Eno" are so small as to be functionally zero. "But the ambitions of Eno are greater than the film itself," writes the Verge, with director Hustwit hoping for a cinematic future exploring generative filmmaking with their software and hardware package. "We have a patent pending on the system, and we just launched a startup called Anamorph that is basically exploring this idea further with other filmmakers and studios and streamers." In an interview with the Verge, Hustwit points out that Brian Eno did the soundtrack for his previous film. "I was having these thoughts about, well, why can't showing a film be more performative? Why does it have to be this static thing every time?" The film just began a two-week run at Greenwich Village's nonprofit theatre Film Forum, and in the U.K. is appearing this week at 17 Picturehouse Cinemas across England and Scotland. Check this online schedule for upcoming dates this week in Nashville (Thursday), Austin (Friday), Dallas (Saturday) — with later dates this month including Toronto, San Francisco, and Los Angeles, and more cities in August.

Scientists Discover How Pancreatic Cancer Switches Off a 'Tumor Suppressor' Gene

✇Slashdot
EditorDavid
An anonymous reader shared this report from the Guardian: A team of researchers from the UK and US have found that pancreatic cancer is able to shut down molecules in one of the body's most important genes, helping the disease to grow and spread rapidly... Dr Maria Hatziapostolou, of Nottingham Trent University's John van Geest Cancer Research Centre, said: "This work, which has provided new understanding and knowledge of how the cancer behaves, will hopefully help pave the way for potential new treatments in the future...." For the study, published in the journal Gastro Hep Advances, the researchers analysed healthy as well as pancreatic cancer tissue samples. They found pancreatic cancers triggered a process known as DNA methylation, causing molecules in the normally beneficial HNF4A gene to switch off, allowing tumours to grow extremely quickly. The HNF4A gene is crucial to human health because it helps many of the body's organs to function properly. But the researchers discovered pancreatic cancer can covertly disable the gene's benefits. Hatziapostolou said: "Loss of HNF4A drives pancreatic cancer development and aggressiveness and we now know correlates with poor patient survival." Scientists from the University of Nottingham, Stanford University and the University of California and Cedars-Sinai medical centre, Los Angeles, were also involved in the project. The published study calls the targeted HNF4A gene is "a novel tumor suppressor in pancreatic cancer, regulating cancer growth and aggressiveness." And ultimately, according to the Guardian, pancreatic cancer "is the 12th most common cancer worldwide," according to the Guardian, "with more than half a million people diagnosed every year. It has the worst survival rates of all the most common forms of the disease." The researchers paper ends with this conclusion. "HNF4A silencing... drives pancreatic cancer development and aggressiveness leading to poor patient survival."

Virgin Galactic Flies 3D Printer Into Space. Its Next Mission: Bioprinting on the ISS

"In a significant advancement for space technology, a team of UC Berkeley researchers, led by doctoral student Taylor Waddell, successfully launched a 3D printer into space," reports the university's student newspaper: As part of the Virgin Galactic 07 mission, the team sent a 3D printer named SpaceCAL to space to explore the potential of Computed Axial Lithography, or CAL, and additive manufacturing in space... During its 140-second flight in suborbital space, the SpaceCAL printer autonomously detected microgravity and printed four test parts: two space shuttles and two Benchies, or 3D-printed boats created to check the printer's accuracy, according to Sean Chu, a member of the team who worked on designing structures and mechanisms. Within the 140 seconds, the process involved multiple steps such as printing, post-washing, flushing with water and post-curing with light to fully solidify the parts. But that's just the beginning, says the university's engineering department: To date, CAL has shown that it can successfully print with more than 60 different materials on Earth, such as silicones, glass composites and biomaterials. According to Waddell, this versatility could come in handy for both the cabin and the crew... "CAL is also capable of repairing the crew. We can print dental replacements, skin grafts or lenses, or things personalized in emergency medicine for astronauts, which is very important in these missions, too." Someday, CAL may be used to print even more sophisticated parts, such as human organs. Lawrence Livermore National Lab has received a grant from NASA to test this technology on the International Space Station. "They're going to basically do bioprinting on the Space Station," said Waddell. "And the long, long-term goal is to print organs up in space with CAL, then bring them back down to Earth." Next, Waddell and his colleagues hope to begin work with NASA on developing and validating a single object that could support crew health and wellness, like a dental crown for an astronaut or a surgical wound closure tool... This project was made possible through a $1.4 million grant and engineering support provided by NASA. In addition, Virgin Galactic played a pivotal role in taking this project to the next level.

Linux Kernel 6.10 Released

✇Slashdot
EditorDavid
"The latest version of the Linux kernel adds an array of improvements," writes the blog OMG Ubuntu, " including a new memory sealing system call, a speed boost for AES-XTS encryption on Intel and AMD CPUs, and expanding Rust language support within the kernel to RISC-V." Plus, like in all kernel releases, there's a glut of groundwork to offer "initial support" for upcoming CPUs, GPUs, NPUs, Wi-Fi, and other hardware (that most of us don't use yet, but require Linux support to be in place for when devices that use them filter out)... Linux 6.10 adds (after much gnashing) the mseal() system call to prevent changes being made to portions of the virtual address space. For now, this will mainly benefit Google Chrome, which plans to use it to harden its sandboxing. Work is underway by kernel contributors to allow other apps to benefit, though. A similarly initially-controversial change merged is a new memory-allocation profiling subsystem. This helps developers fine-tune memory usage and more readily identify memory leaks. An explainer from LWN summarizes it well. Elsewhere, Linux 6.10 offers encrypted interactions with trusted platform modules (TPM) in order to "make the kernel's use of the TPM reasonably robust in the face of external snooping and packet alteration attacks". The documentation for this feature explains: "for every in-kernel operation we use null primary salted HMAC to protect the integrity [and] we use parameter encryption to protect key sealing and parameter decryption to protect key unsealing and random number generation." Sticking with security, the Linux kernel's Landlock security module can now apply policies to ioctl() calls (Input/Output Control), restricting potential misuse and improving overall system security. On the networking side there's significant performance improvements to zero-copy send operations using io_uring, and the newly-added ability to "bundle" multiple buffers for send and receive operations also offers an uptick in performance... A couple of months ago Canonical announced Ubuntu support for the RISC-V Milk-V Mars single-board computer. Linux 6.10 mainlines support for the Milk-V Mars, which will make that effort a lot more viable (especially with the Ubuntu 24.10 kernel likely to be v6.10 or newer). Others RISC-V improvements abound in Linux 6.10, including support for the Rust language, boot image compression in BZ2, LZ4, LZMA, LZO, and Zstandard (instead of only Gzip); and newer AMD GPUs thanks to kernel-mode FPU support in RISC-V. Phoronix has their own rundown of Linux 6.10, plus a list of some of the highlights, which includes: The initial DRM Panic infrastructure The new Panthor DRM driver for newer Arm Mali graphics Better AMD ROCm/AMDKFD support for "small" Ryzen APUs and new additions for AMD Zen 5. AMD GPU display support on RISC-V hardware thanks to RISC-V kernel mode FPU More Intel Xe2 graphics preparations Better IO_uring zero-copy performance Faster AES-XTS disk/file encryption with modern Intel and AMD CPUs Continued online repair work for XFS Steam Deck IMU support TPM bus encryption and integrity protection

How Will AI Transform the Future of Work?

✇Slashdot
EditorDavid
An anonymous reader shared this report from the Guardian: In March, after analysing 22,000 tasks in the UK economy, covering every type of job, a model created by the Institute for Public Policy Research predicted that 59% of tasks currently done by humans — particularly women and young people — could be affected by AI in the next three to five years. In the worst-case scenario, this would trigger a "jobs apocalypse" where eight million people lose their jobs in the UK alone.... Darrell West, author of The Future of Work: AI, Robots and Automation, says that just as policy innovations were needed in Thomas Paine's time to help people transition from an agrarian to an industrial economy, they are needed today, as we transition to an AI economy. "There's a risk that AI is going to take a lot of jobs," he says. "A basic income could help navigate that situation." AI's impact will be far-reaching, he predicts, affecting blue- and white-collar jobs. "It's not just going to be entry-level people who are affected. And so we need to think about what this means for the economy, what it means for society as a whole. What are people going to do if robots and AI take a lot of the jobs?" Nell Watson, a futurist who focuses on AI ethics, has a more pessimistic view. She believes we are witnessing the dawn of an age of "AI companies": corporate environments where very few — if any — humans are employed at all. Instead, at these companies, lots of different AI sub-personalities will work independently on different tasks, occasionally hiring humans for "bits and pieces of work". These AI companies have the potential to be "enormously more efficient than human businesses", driving almost everyone else out of business, "apart from a small selection of traditional old businesses that somehow stick in there because their traditional methods are appreciated"... As a result, she thinks it could be AI companies, not governments, that end up paying people a basic income. AI companies, meanwhile, will have no salaries to pay. "Because there are no human beings in the loop, the profits and dividends of this company could be given to the needy. This could be a way of generating support income in a way that doesn't need the state welfare. It's fully compatible with capitalism. It's just that the AI is doing it."

The World's Population Is Projected To Peak At 10.3 Billion In the 2080s

Long-time Slashdot reader Geoffrey.landis writes: According to a new report from the United Nations, the world population is expected to grow to an estimated peak of 10.3 billion people in the mid-2080s, an increase over the current global population of 8.2 billion people. The estimated world population at the end of the century (2100) is now expected to be 6% less than estimates from a decade ago. However, calculating the number of future people is not a perfect science, with "many sources of uncertainty in estimating the global population," according to the U.S. Census Bureau. It estimated the world reached 8 billion people last September, while the U.N. timed the milestone nearly one year earlier.

To Avoid Sea Level Rise, Some Researchers Propose Barriers Around the World's Vulnerable Glaciers

✇Slashdot
EditorDavid
"Researchers are proposing a new way to battle the effects of climate change..." writes Science magazine: slowing the rising of sea levels with "glacial geoengineering". (That is, "building flexible barriers around them or drilling deep into them to slow their slippage into the sea.") Geoengineering proponents say it would be better to begin research now on how to staunch sea level rise at its source, rather than spending billions and billions of dollars to wall off coastal cities. "At some point you have to think, 'Well, is there anything else we can do?'" asks glaciologist John Moore of the University of Lapland, an author on the white paper, which was sponsored by the University of Chicago. One idea researched by Moore and covered in the report is to build buoyant "curtains," moored to the sea floor beyond the edge of ice shelves and glaciers, to block natural currents of warm water that erode ice sheets from below. (Especially in Antarctica, warming ocean water is a bigger threat to glaciers than warming air.) Early designs called for plastic, but natural fibers such as canvas and sisal are now being considered to avoid pollution concerns. According to the white paper, initial modeling studies show that curtain heights stretching only partway up from the sea floor off the coast of western Antarctica could reduce glacial melting by a factor of 10 in some locations. Another intervention some scientists are contemplating would slow the slippage of ice sheets by drilling holes to their bases and pumping out water or heat. Such massive engineering efforts would surely be some of the most expensive ever undertaken by humanity. At a workshop at the University of Chicago in October 2023, researchers suggested it might cost $88 billion to build 80 kilometers of curtains around Antarctic glaciers. Interventions would also require international political support, which some glaciologists view as an even bigger hurdle than the price tag. Twila Moon, a glaciologist at the U.S. National Snow and Ice Data Center, says such projects would require fleets of icebreakers, extensive shipping and supply chain needs, and significant personnel to construct, maintain, and guard the final structures — in ocean conditions she calls "eye-poppingly difficult." The projects could also incur unintended consequences, potentially disrupting ocean circulation patterns or endangering wildlife. Furthermore, it would take decades to find out whether the interventions were working. Even if the engineering and logistics were possible, that "does not answer the question of whether it should be pursued," says Moon, who opposes even preliminary studies on the concepts. "The report, which also stresses the importance of emissions reductions, takes pains to say it 'does not advocate for intervention; rather, it advocates for research into whether any interventions may be viable'..."

How Microsoft, Dell and Other Large US Employers Accommodate Neurodivergent Employees

✇Slashdot
EditorDavid
As the number of autism diagnoses rises in America, a number of large employers "are taking steps to make workplaces more accessible and welcoming for neurodivergent employees," reports the New York Times — including Microsoft, Dell and Ford. [Alternate URL here.] The Centers for Disease Control and Prevention estimates that 1 in 36 8-year-olds in the United States has autism. That's up from 1 in 44 in 2018 and 1 in 150 in 2000, an increase that experts attribute, in part, to better screening. In addition, 2.2% of adults in the country, or 5.4 million people, are autistic, according to the CDC... Autism activists have praised companies that have become more accepting of remote work since the coronavirus pandemic. Workplaces with too much light and noise can overwhelm those who are autistic, leading to burnout, said Jessica Myszak, a clinical psychologist in Chicago who specializes in testing and evaluations for autism. Remote work "reduces the social demands and some of the environmental sensitivities" that autistic people struggle with, Myszak added. The article notes Microsoft's neurodiversity hiring program, which was established in 2015. The company's program was modeled after a venture created by the German software firm SAP, and has since been adopted in some form by companies including Dell and Ford. The initiative has brought in about 300 full-time neurodivergent employees to Microsoft, said Neil Barnett, the company's director for inclusive hiring and accessibility. "All they needed was this different, more inclusive process," Barnett said, "and once they got into the company, they flourished." [One job applicant] was given a job coach to help her with time management and prioritization. Microsoft also paired her with a mentor who showed her around the company's campus in Redmond. Perhaps more important, she works with managers who have received neurodiversity training. The Microsoft campus also has "focus rooms," where lights can be dimmed and the heights of desks can be changed to fit sensory preferences. Employees seated in the open office may also request to sit away from busy aisles or receive noise-canceling headphones.

AT&T Paid $370,000 For the Deletion of Stolen Phone Call Records

✇Slashdot
EditorDavid
AT&T paid more than $300,000 to a member of the team that stole call records for tens of millions of customers, reports Wired — "to delete the data and provide a video demonstrating proof of deletion." The hacker, who is part of the notorious ShinyHunters hacking group that has stolen data from a number of victims through unsecured Snowflake cloud storage accounts, tells WIRED that AT&T paid the ransom in May. He provided the address for the cryptocurrency wallet that sent the currency to him, as well as the address that received it. WIRED confirmed, through an online blockchain tracking tool, that a payment transaction occurred on May 17 in the amount of 5.7 bitcoin... The hacker initially demanded $1 million from AT&T but ultimately agreed to a third of that. WIRED viewed the video that the hacker says he provided to AT&T as proof to the telecom that he had deleted its stolen data from his computer... AT&T is one of more than 150 companies that are believed to have had data stolen from poorly secured Snowflake accounts during a hacking spree that unfolded throughout April and May. It's been previously reported that the accounts were not secured with multi-factor authentication, so after the hackers obtained usernames and passwords for the accounts, and in some cases authorization tokens, they were able to access the storage accounts of companies and siphon their data. Ticketmaster, the banking firm Santander, LendingTree, and Advance Auto Parts were all among the victims publicly identified to date... The timeline suggests that if [John] Binns is responsible for the AT&T breach, he allegedly did it when he was likely already aware that he was under indictment for the T-Mobile hack and could face arrest for it.

Thunderbird 128: Annual ESR Brings New Features and 'a Rust Revolution'

✇Slashdot
EditorDavid
Thunderbird's annual Extended Support Release was revealed Friday, promising "significant" improvements to the overall user experience and "the speed at which we can deliver new features to you," according to the Thunderbird blog: We've devoted significant development time integrating Rust — a modern programming language originally created by Mozilla Research — into Thunderbird. Even though this is a seemingly invisible change, it is a major leap forward because it enhances our code quality and performance. This overhaul will allow us to share features between the desktop and future mobile versions of Thunderbird, and speed up our development process. It's a win for our developers and a win for you. More from the blog OMG Ubuntu: I'm also stoked to see that Thunderbird 128 makes 'newest first' the default sort order for messages in message list. While some prefer the old way, I always found it strange that the oldest mails were shown first — team reverse chronology, represent! They also cite "a number of OpenPGP improvements," plus a new preference option for displaying full names and email addresses of all recipients in the message list. (Plus, threaded-message views now display a "New Message" count.) Other new features in this release: A new and more attractive layout for Cards View (with adjustable heights) that "makes it easier to scan your email threads and glean information." The folder pane has better recall of message thread states Improved theme compatibility. "Your Thunderbird should blend seamlessly with your desktop environment, matching the system's accent colors perfectly." (Especially beneficial on Ubuntu and Mint.) You can now customize the color of your account icon. The Thunderbird blog also mentions that "We plan to launch the first phase of built-in support for Exchange, as well as Mozilla Sync, in a future Nebula point release (e.g. Thunderbird 128.X)."

California Prohibited From Enforcing PI Licensing Law Against Anti-Spam Crusader

✇Slashdot
EditorDavid
Long-time Slashdot reader schwit1 shared this report from non-profit libertarian law firm, the Institute for Justice: U.S. District Judge Rita Lin has permanently enjoined the California Bureau of Security and Investigative Services from enforcing its private-investigator licensing requirement against anti-spam entrepreneur Jay Fink. The order declares that forcing Jay to get a license to run his business is so irrational that it violates the Due Process Clause of the Fourteenth Amendment... Jay's business stems from California's anti-spam act, which allows individuals to sue spammers. But to sue, they have to first compile evidence. To do that, recipients often have to wade through thousands of emails. For more than a decade, Jay has offered a solution: he and his team will scour a client's junk folder and catalog the messages that likely violate the law. But last summer, Jay's job — and Californians' ability to bring spammers to justice — came to a screeching halt when the state told him he was a criminal. A regulator told Jay he needed a license to read through emails that might be used as evidence in a lawsuit. And because Jay didn't have a private investigator license, the state shut him down. The state of California has since "agreed to jointly petition the court for an order that forever prohibits it from enforcing its licensure law against Jay," according to the article. Otherwise the anti-spam crusader would've had to endure thousands of hours of private investigator training...

Apple Approves PC/Linux/Mac-Emulating App 'UTM SE' for App Store, Reversing Earlier Rejection

✇Slashdot
EditorDavid
At the end of June, Apple's App Store rejected the Windows/retro PC emulator "UTM SE". But in a reversal Apple approved the app Saturday, reports the Verge. "We are happy to announce that UTM SE is available (for free) on iOS and visionOS App Store," the developer posted on X, "and coming soon to AltStore PAL." From the Verge: After Apple rejected the app in June, the developer said it wasn't going to keep trying because the app was "a subpar experience." Today, UTM thanked the AltStore team for helping it and credited another developer "whose QEMU TCTI implementation was pivotal for this JIT-less build." As with other emulators on the App Store, you can't do much with UTM SE out of the box. It doesn't come with any operating systems, though the app does link to UTM's site, which has guides for Windows XP through Windows 11 emulation, as well as downloads of pre-built virtual Linux machines. Mac OS 9.2.1 and DOS are listed in one screenshot from the UTM SE App Store page. Mac OS 9.2.1 and DOS are listed in one screenshot from the UTM SE App Store page.
