Greg Kroah-Hartman Supports Rust in the Kernel

3 months 2 weeks ago
An anonymous Slashdot reader shared this report from Phoronix: Linux's second-in-command Greg Kroah-Hartman has also been a big proponent of Rust kernel code. He's crafted another Linux kernel mailing list post [Wednesdsay] outlining the benefits of Rust and encouraging new kernel code/drivers to be in Rust rather than C. Greg KH makes the case that the majority of the kernel bugs are due to "stupid little corner cases in C that are totally gone in Rust." "As someone who has seen almost EVERY kernel bugfix and security issue for the past 15+ years... and who sees EVERY kernel CVE issued, I think I can speak on this topic," Kroah-Hartman began. Here's some excerpts from his remarks. Citing corner cases like overwrites of memory, error path cleanups, use-after-free mistakes and forgetting to check error values, Kroah-Hartman says he's "all for... making these types of problems impossible to hit." That's why I'm wanting to see Rust get into the kernel, these types of issues just go away, allowing developers and maintainers more time to focus on the REAL bugs that happen (i.e. logic issues, race conditions, etc.)... [F]or new code / drivers, writing them in Rust where these types of bugs just can't happen (or happen much much less) is a win for all of us, why wouldn't we do this...? Rust isn't a "silver bullet" that will solve all of our problems, but it sure will help in a huge number of places, so for new stuff going forward, why wouldn't we want that...? Yes, mixed language codebases are rough, and hard to maintain, but we are kernel developers dammit, we've been maintaining and strengthening Linux for longer than anyone ever thought was going to be possible. We've turned our development model into a well-oiled engineering marvel creating something that no one else has ever been able to accomplish. Adding another language really shouldn't be a problem, we've handled much worse things in the past and we shouldn't give up now on wanting to ensure that our project succeeds for the next 20+ years. We've got to keep pushing forward when confronted with new good ideas, and embrace the people offering to join us in actually doing the work to help make sure that we all succeed together. Kroah-Hartman emphasized later that "a huge majority of the stupid things we do in C just don't happen in the same code implemented in Rust (i.e. memory leaks, error path cleanups, return value checking, etc.) " The complete thread contains over 140 messages — including Linus Torvalds' observation that " #pragma is complete garbage and should never be used."

Mozilla Wants to Expand from Firefox to Open-Source AI and Privacy-Respecting Ads

3 months 2 weeks ago
On Wednesday Mozilla president Mark Surman "announced plans to tackle what he says are 'major headwinds' facing the company's ability to grow, make money, and remain relevant," reports the blog OMG Ubuntu: "Mozilla's impact and survival depend on us simultaneously strengthening Firefox AND finding new sources of revenue AND manifesting our mission in fresh ways," says Surman... It will continue to invest in privacy-respecting advertising; fund, develop and push open-source AI features in order to retain 'product relevance'; and will go all-out on novel new fundraising initiatives to er, get us all to chip in and pay for it! Mozilla is all-in on AI; Surman describes it as Mozilla's North Star for the work it will do over the next few years. I wrote about its new 'Orbit' AI add-on for Firefox recently... Helping to co-ordinate, collaborate and come up with ways to keep the company fixed and focused on these fledgling effort is a brand new Mozilla Leadership Council. The article argues that without Mozilla the web would be "a far poorer, much ickier, and notably less FOSS-ier place..." Or, as Mozilla's blog post put it Wednesday, "Mozilla is entering a new chapter — one where we need to both defend what is good about the web and steer the technology and business models of the AI era in a better direction. "I believe that we have the people — indeed, we ARE the people — to do this, and that there are millions around the world ready to help us. I am driven and excited by what lies ahead."

Elon Musk Urges Deorbiting the International Space Station 'As Soon as Possible'

3 months 2 weeks ago
An anonymous reader shared this report from ABC News: Elon Musk called this week for the deorbiting of the International Space Station (ISS) "as soon as possible." "It is time to begin preparations for deorbiting the [ISS]," Musk wrote in a post on X on Thursday. "It has served its purpose. There is very little incremental utility. Let's go to Mars." In a follow-up post, Musk said he was planning to recommend to President Donald Trump that the station be brought down "as soon as possible" and that the 2030 timeline for deorbiting be moved up to two years from now. Jordan Bimm, space historian and professor of science communication at the University of Chicago, told ABC News what he thinks was one of the most important findings to come out of ISS research: "that microgravity affects the body in lots of deleterious ways." "That leads to your bone loss, muscle loss, changes in the fluid inside our bodies that are normally being pulled down by Earth's gravity, changes to the eye and vision loss and things like that. We have gotten good data on how that progresses over time, and importantly, we have developed countermeasures for these things as well, including resistance training or running on a treadmill, things like that..."

Unexpected Shape of Lead-208 Nucleus May Force Scientists to Reevaluate Atomic Nuclei Models

3 months 2 weeks ago
"An international research collaboration led by the University of Surrey's Nuclear Physics Group has overturned the long-standing belief that the atomic nucleus of lead-208 is perfectly spherical," reports Phys.org. They add that the discovery "challenges fundamental assumptions about nuclear structure and has far-reaching implications for our understanding of how the heaviest elements are formed in the universe..." [A] new study published in Physical Review Letters used a high-precision experimental probe to examine its shape and found that rather than being perfectly spherical, the nucleus of lead-208 is slightly elongated, resembling a rugby ball (prolate spheroid)... Using the state-of-the-art GRETINA gamma-ray spectrometer at Argonne National Laboratory in Illinois, U.S., scientists bombarded lead atoms with high-speed particle beams accelerated to 10% of the speed of light — equivalent to circling the Earth every second. The interactions created unique gamma-ray fingerprints of the properties of excited quantum states in lead-208 nuclei — in other words, the nuclei were energized — which, in turn, were used to determine its shape. Theoretical physicists, including those at the Surrey Nuclear Theory Group, are now re-examining the models used to describe atomic nuclei, as the experiments suggest that nuclear structure is far more complex than previously thought.

Amazon Is Killing the Ability to Download eBooks to Your Computer

3 months 2 weeks ago
"Amazon has long allowed you to download its ebooks to your computer," notes PCMag.com, "where they can serve as a backup or be transferred to other devices. "However, that feature will end on February 26, 2025, along with the ability to transfer books from your computer to your Kindle via USB." If you attempt to download your ebooks right now, a message says: "Starting February 26, 2025, the 'Download & Transfer via USB' option will no longer be available. You can still send Kindle books to your Wi-Fi-enabled devices by selecting the 'Deliver or Remove from Device' option." After February 26, you will still be able to download Kindle books [onto your Kindle] from the Kindle Store via Wi-Fi, and you can also use the Send to Kindle page on Amazon to send a variety of files to your Kindle. Should you want to transfer your titles from your Kindle to your computer while you still can, go to Amazon.com, sign in, and click Accounts & Lists > Content Library > Books. Navigate to the book you want to download and click More actions > Download & transfer via USB. Tom's Guide shares their reaction: Most people probably won't notice this latest example of an Amazon service getting worse, but the feature has existed for over a decade and is useful for backing up your purchases or converting them to formats compatible with other non-Kindle e-Readers or devices. It's also useful for those times when you don't have access to Wi-Fi, and of course, there's peace of mind knowing you have copies of your books... All in all it is a reminder that you don't actually own many or most of your digital purchases, as what you are typically actually "buying" are licenses to use content that can be revoked at any time. If you find this decision annoying and want to find alternatives, here are a few. To start, might we recommend the Libby app which lets you borrow ebooks from your local library. You can also borrow audiobooks... You can also try purchasing books from places like Google Books and Apple Books, both of which offer a number of ebooks. eBooks.com offers DRM free books and EPUB formats. For those looking for free ebooks there is always Project Gutenberg which has over 75,000 free books largely those in the public domain though there are some more recent titles as well.

Lithium Batteries Reignited Tuesday at the Moss Landing Power Plant Fire Site

3 months 2 weeks ago
Remember that battery plant fire last month in Moss Landing, California? Tuesday night local firefighters "determined that a group of lithium batteries in an area that had previously burned during the January 16 fire had smoldered and reignited," reports SFGate. Fire Chief Joel Mendoza said the flames burned at varying intensities throughout Tuesday night before the fire burned itself out at about 8 a.m. on Wednesday. Additional flare-ups at the site are expected due to weather exposure and damage to the remaining batteries. "Rekindling is very, very likely — almost a certainty," said EPA onsite coordinator Eric Sandusky, adding that rain and humidity can interact with the damaged batteries, leading to short circuits and reignition. To further reduce fire risk, Sandusky said the EPA is working with Vistra to begin "de-linking the batteries," a process that disconnects them to lower the risk of propagation and prevent a large-scale fire... "Vistra said that since the January 16 fire, they have brought in a private fire crew that is on-site at all times to monitor the Moss 300 building," according to a local news site. Fire Chief Joel Mendoza shared more details with the digital newspaper Lookout Santa Cruz. "We've been saying all along that batteries exposed to heat that didn't burn can ignite. We were hoping that it wouldn't happen, but it did."

AI May Not Impact Tech-Sector Employment, Projects US Department of Labor

3 months 2 weeks ago
America's Labor Department includes the fact-finding Bureau of Labor Statistics — and they recently explained how AI impacts their projections for the next 10 years. Their conclusion, writes Investopedia, was that "tech workers might not have as much to worry about as one might think." Employment in the professional, scientific, and technical services sector is forecast to increase by 10.5% from 2023 to 2033, more than double the national average. According to the BLS, the impact AI will have on tech-sector employment is highly uncertain. For one, AI is adept at coding and related tasks. But at the same time, as digital systems become more advanced and essential to day-to-day life, more software developers, data managers, and the like are going to be needed to manage those systems. "Although it is always possible that AI-induced productivity improvements will outweigh continued labor demand, there is no clear evidence to support this conjecture," according to BLS researchers. Their employment projections through 2033 predict the fastest-growing sector within the tech industry will be computer system design, while the fastest-growing occupation will be data scientist. And they also project that from 2023 through 2033 AI will "primarily affect occupations whose core tasks can be most easily replicated by GenAI in its current form." So over those 10 years they project a 4.7% drop in employment of medical transcriptionists and a 5.0% drop in employment of customer service representatives. Other occupations also may see AI impacts, although not to the same extent. For instance, computer occupations may see productivity impacts from AI, but the need to implement and maintain AI infrastructure could in actuality boost demand for some occupations in this group. They also project decreasing employment for paralegals, but with actual lawyers being "less affected."

Will Consumer Data Collection Lead to Algorithm-Adjusted 'Surveillance Pricing'?

3 months 2 weeks ago
An anonymous reader shared this report from the Washington Post's "Tech Brief": Last fall, reports that Kroger was considering bringing facial recognition technology into its stores sparked outcry from lawmakers and customers. They worried personalized data could be used to charge different prices for different customers based on their shopping habits, financial circumstances or appearance. Kroger, the country's largest supermarket chain, had already been using digital price tags in its stores. Kroger told lawmakers that it doesn't use facial recognition to help it set prices, a stance the company reiterated to the Tech Brief on Thursday. Still, the uproar helped to spark a push by consumer advocates who warn that the threat of invasive, personalized pricing schemes is real. Now, Democratic lawmakers in several states are working to ban so-called "surveillance pricing" — when businesses charge customers more or less for the same item based on their personal information. Besides a bill in California, three more bill were introduced this month in Colorado, Georgia, and Illinois that also ban "surveillance wages," which the article defines as employers adjusting wages based on how much data an employee collects. "Both surveillance pricing and surveillance wages really disrupt fundamental ideals of fairness," University of California, Irvine law professor Veena Dubal tells the Washington Post. Dubal is one of the consumer advocates behind a new report which notes information released last month by America's consumer-protecting FTC that "suggests that surveillance pricing tools are being actively developed and marketed across a range of industries, including consumer-facing businesses like 'grocery stores, apparel retailers, health and beauty retailers, home goods and furnishing stores, convenience stores, building and hardware stores, and general merchandise retailers such as department or discount stores." The consumer advocates (which include the Electronic Privacy Information Center) put it this way. "Imagine walking into a grocery store and seeing a price for milk that's higher than what the next shopper pays because an algorithm calculated that you're willing to spend more..."
