There are things which are true. Regular expressions frequently perform badly. They're hard to read. Email addresses are not actually regular languages, and thus can't truly be validated (in all they're many possible forms) by a pure regex.

These are true. It's also true that a simple regex can get you most of the way there.

Lucas found this in their codebase, for validating emails.

function echeck(str) { var at="@"; var dot="."; var lat=str.indexOf(at); var lstr=str.length; var ldot=str.indexOf(dot); if (str.indexOf(at)==-1){ alert("You must include an accurate email address for a response."); return false; } if (str.indexOf(at)==-1 || str.indexOf(at)==0 || str.indexOf(at)==lstr){ alert("You must include an accurate email address for a response."); return false; } if (str.indexOf(dot)==-1 || str.indexOf(dot)==0 || str.indexOf(dot)==lstr){ alert("You must include an accurate email address for a response."); return false; } if (str.indexOf(at,(lat+1))!=-1){ alert("You must include an accurate email address for a response."); return false; } if (str.substring(lat-1,lat)==dot || str.substring(lat+1,lat+2)==dot){ alert("You must include an accurate email address for a response."); return false; } if (str.indexOf(dot,(lat+2))==-1){ alert("You must include an accurate email address for a response."); return false; } if (str.indexOf(" ")!=-1){ alert("You must include an accurate email address for a response."); return false; } return true; }

It checks that the string contains an "@", and the "@" is not at the beginning or end of the string. Then it does the same check for a ".". Then it checks that there isn't a second "@". Then it checks that there are at least two non-"@" characters before the ".". Then it checks that there's at least one "." after the "@". Then it checks that there are no spaces.

Like a regex, I don't think this covers the entire space of valid and invalid email addresses, but that's just because the email address spec is complicated. It likely qualifies as "good enough", on that front. But it's the most awkward way to express that series of tests, especially since they create variables which might be useful, but never use them, thus calling str.indexOf many, many times. The awkwardness becomes more obvious with the way it outputs the same error message in multiple branches. Outputs them using alert I might add, which is the kind of choice that should send someone to the Special Hell™.

It's a feature-length film "rendered on a free and open-source software platform called Blender," reports Reuters. And it just won the Oscar for best animated feature film, beating movies from major studios like Disney/Pixar and Dreamworks. In January Blender.org called Flow "the manifestation of Blender's mission, where a small, independent team with a limited budget is able to create a story that moves audiences worldwide, and achieve recognition with over 60 awards, including a Golden Globe for Best Animation and two Oscar nominations." The entire project cost just $3.7 million, reports NPR — though writer/director Gints Zilbalodis tells Blender.org that it took about five and a half years. "I think a certain level of naivety is necessary when starting a project," Zilbalodis tells Blender. "If I had known how difficult it would be, I might never have started. But because I didn't fully grasp the challenges ahead, I just dove in and figured things out along the way..." Zilbalodis: [A]fter making a few shorts, I realized that I'm not good at drawing, and I switched to 3D because I could model things, and move the camera... After finishing my first feature Away, I decided to switch to Blender [from Maya] in 2019, mainly because of EEVEE... It took a while to learn some of the stuff, but it was actually pretty straightforward. Many of the animators in Flow took less than a week to switch to Blender... I've never worked in a big studio, so I don't really know exactly how they operate. But I think that if you're working on a smaller indie-scale project, you shouldn't try to copy what big studios do. Instead, you should develop a workflow that best suits you and your smaller team. You can get a glimpse of their animation style in Flow's official trailer. NPR says that ultimately Flow's images "possess a kinetic elegance. They have the alluring immersiveness of a video game..."

What's Linux's marketshare on Steam? The Steam Survey numbers tell this story: 11/24: 2.03% 12/24: 2.29% 01/25: 2.06% 02:25: 1.45% "The February numbers show a staggering 0.61% drop to Linux use..." reports Phoronix. But they attribute this to an sampling error: According to the survey, it shows 50% of Steam users using the Simplified Chinese language pack [a 20% increase from the month before]. In prior months where there has been drops to Linux use, it's been correlated to wild swings in the Chinese use on Steam. This looks to be another such month. Of the Linux specific data, SteamOS continues to prove most popular for that Valve distribution powering the Steam Deck [at 34.67%, with Arch Linux coming in second at 9.7%]. AMD CPUs power around 70% of the Linux gaming systems thanks to the Steam Deck APU and AMD Ryzen being quite popular with Linux enthusiasts.

Lenovo demonstrated "a laptop with a foldable screen and one that can get extra battery life from solar power," reports CNBC, emphasizing that "These laptops are just concepts, meaning they are not commercially available." But "Lenovo, the world's biggest PC maker, has a history of showing off imaginative concepts with some becoming reality, so it's worth keeping an eye on what the Chinese technology giant is up to..." The latest concepts were unveiled at the Mobile World Congress trade show in Barcelona... When fully unfolded, the screen is an 18-inch display [on the Lenovo ThinkBook 'flip' concept]... The screen can then be folded in half horizontally to create two screens — one on the front and one on the back. The entire display can be folded down flat so the laptop turns into a tablet-like device. Lenovo also showed off a Yoga Solar PC concept, reports Gizmodo, calling it "relatively thin and light" despite a solar panel in its lid with "a supposed 24% solar conversion rate": Lenovo claims they achieved this by maneuvering the gridlines you usually find on a solar panel behind the solar cells, offering more real estate for energy absorption... Lenovo's software showed the power accumulation at around 7 V when facing away from the sunlight and 12 V when facing toward it. It could get more when getting direct sunlight. Despite the presence of the solar panel, the laptop still weighs a little more than 2.6 pounds, which isn't out of the realm of what to expect from most modern laptops. We should note that the panel isn't generating the required power to run the PC continuously. Lenovo claimed that 20 minutes of direct sunlight will transform into about one hour of video playback battery life. Depending on the CPU and battery, that could be 1/20 of the laptop's battery life. CNBC had slightly different statistics for the laptop's battery life. "Lenovo said that the solar panels can absorb even ambient light in a person's surroundings to give a user an extra hour of laptop use at the end of an eight-hour work day..."

Despite a January announcement that America would explore the idea of a national digital asset stockpile, the exact cryptocurrecies weren't specified. Today on social media the president posted that it would include bitcoin, ether, XRP, Solana's SOL token and Cardano's ADA, reports CNBC — prompting a Sunday rally in cryptocurrencies trading. XRP surged 33% after the announcement while the token tied to Solana jumped 22%. Cardano's coin soared more than 60%. Bitcoin rose 10% to $94,425.29, after dipping to a three-month low under $80,000 on Friday. Ether, which has suffered some of the biggest losses in crypto year-to-date, gained 12%... This is the first time Trump has specified his support for a crypto "reserve" versus a "stockpile." While the former assumes actively buying crypto in regular installments, a stockpile would simply not sell any of the crypto currently held by the U.S. government. "The total cryptocurrency market has risen about 10%," reports Reuters, "or more than $300 billion, in the hours since Trump's announcement, according to CoinGecko, a cryptocurrency data and analysis company." "A U.S. Crypto Reserve will elevate this critical industry..." the president posted, promising to "make sure the U.S. is the Crypto Capital of the World," reports The Hill: His announcement comes just after the White House announced it would be welcoming cryptocurrency industry professionals on March 7 in a first-of-its-kind summit... It's unclear what exactly Trump's crypto reserve would look like, and while he previously dismissed crypto as a scam, he's embraced the industry throughout his most recent campaign.

Earth's core "burns with an estimated forty-four trillion watts of power," the New Yorker reminds us — enough to "satisfy the entire world's energy needs" with a power source that's carbon-free, ubiquitous — and unlimited. (Besides running 24 hours a day, one of geothermal energy's key advantages is "it can be used for both electricity and heating, which collectively account for around 38% of global climate emissions...") And one drilling expert tells them there's been an "exponential spin-up of activity in geothermal" energy projects over the last two years. (Ironically it was the fracking boom also brought an "explosion of new drilling practices — such as horizontal drilling and magnetic sensing — that inspired a geothermal resurgence.") In 2005 one research team calculated that just 2% of the heat just four miles underground in America "could meet the entire country's energy needs — two thousand times over," according to the article. So their new article checks in on the progress of geothermal energy projects around the world, including a Utah company using a diamond-bit drill to dig nearly a mile into the earth to install a 150-ton steel tube surrounded by special heat-resistant cement — all to create "a massive straw" for transporting hot water (and steam). The biggest problem is drilling miles through hot rock, safely. If scientists can do that, however, next-generation geothermal power could supply clean energy for eons... At 6:15 P.M. on May 3rd, cement had started flowing into the hole. Four hours later, part of the cement folded in on itself. The next morning, the cement supply ran out; the men had miscalculated how much they needed. This brought the three-hundred-million-dollar operation to a maddening halt... The cement truck from Bakersfield arrived around 8:30 P.M. By ten-thirty, the men were pouring cement again, gluing the enormous metal straw in place. Next, the team scanned the borehole with gamma rays...

"Thousands of buildings across the United States are staying cool with the help of cutting-edge batteries made from one of the world's simplest materials," reports the Washington Post — ice. When electricity is cheap, the batteries freeze water. When energy costs go up, building managers turn off their pricey chillers and use the ice to keep things cool. A typical building uses about a fifth of its electricity for cooling, according to the International Energy Agency. By shifting their energy use to cheaper times of day, the biggest buildings can save hundreds of thousands of dollars a year on their power bills. They can also avoid using electricity from the dirtiest fossil fuel plants. In places where the weather is hot and energy prices swing widely throughout the day — for instance, Texas, Southern California and most of the American Southwest — buildings could cut their power bills and carbon emissions by as much as a third, experts say... When every building is blasting its air conditioner at the same moment on a hot day, power companies often fire up backup generators, known as peaker plants, which are generally extra pricey and polluting. If utilities avoid using peaker plants, they'll pollute less and save money. Last year, the Energy Department struck a tentative $306 million loan deal with the ice-battery-maker Nostromo Energy to install its systems in 193 California buildings to make energy cheaper and cleaner while lowering the state's blackout risk. "The batteries themselves are huge..." the article acknowledges, citing one in New York City that uses 100 parking spot-sized tanks "which collectively make 3 million margaritas' worth of ice each night... But that's starting to change." (And they believe new smaller designs "could bring the batteries into smaller buildings and even houses.") Wherever they can squeeze into the market, ice batteries could be a cheaper and longer-lasting option than the lithium-ion batteries that power phones, cars and some buildings because their main ingredient is water, experts say. The pricey chemicals in a lithium-ion cell might degrade after 10 years, but water never wears out. And according to the article, one company has already installed ice batteries in over 4,000 buildings...

A "decision science partner" at a seed-stage venture fund (who is also a cognitive-behavioral decision science author and professional poker player) explored what happens when GPT-4 Turbo converses with conspiracy theorists: Researchers have struggled for decades to develop techniques to weaken the grip of conspiracy theories and cult ideology on adherents. This is why a new paper in the journal Science by Thomas Costello of MIT's Sloan School of Management, Gordon Pennycook of Cornell University and David Rand, also of Sloan, is so exciting... In a pair of studies involving more than 2,000 participants, the researchers found a 20 percent reduction in belief in conspiracy theories after participants interacted with a powerful, flexible, personalized GPT-4 Turbo conversation partner. The researchers trained the AI to try to persuade the participants to reduce their belief in conspiracies by refuting the specific evidence the participants provided to support their favored conspiracy theory. The reduction in belief held across a range of topics... Even more encouraging, participants demonstrated increased intentions to ignore or unfollow social media accounts promoting the conspiracies, and significantly increased willingness to ignore or argue against other believers in the conspiracy. And the results appear to be durable, holding up in evaluations 10 days and two months later... Why was AI able to persuade people to change their minds? The authors posit that it "simply takes the right evidence," tailored to the individual, to effect belief change, noting: "From a theoretical perspective, this paints a surprisingly optimistic picture of human reasoning: Conspiratorial rabbit holes may indeed have an exit. Psychological needs and motivations do not inherently blind conspiracists to evidence...." It is hard to walk away from who you are, whether you are a QAnon believer, a flat-Earther, a truther of any kind or just a stock analyst who has taken a position that makes you stand out from the crowd. And that's why the AI approach might work so well. The participants were not interacting with a human, which, I suspect, didn't trigger identity in the same way, allowing the participants to be more open-minded. Identity is such a huge part of these conspiracy theories in terms of distinctiveness, putting distance between you and other people. When you're interacting with AI, you're not arguing with a human being whom you might be standing in opposition to, which could cause you to be less open-minded. Answering questions from Slashdot readers in 2005, Wil Wheaton described playing poker against the cognitive-behavioral decision science author who wrote this article...

Can a new 3D-printing technique shorten 3D printing times to just seconds? A team of researchers in Europe has modified Tomographic Volumetric Additive Manufacturing, which can "create entire objects in one shot by shining light patterns into liquid resin," according to the 3D Printing Industry blog. (The liquid resin then solidifies when the light intensity is high enough...) While this approach can fabricate support-free, micro-scale parts within tens of seconds, it is "highly inefficient." This is because under 1% of the encoded light reaches the resin vial. Conventional TVAM can also lead to unwanted distortions and poor resolution due to light blurring and projection artifacts. To address these limitations, the researchers developed HoloVAM, a new technique that uses a 3D hologram instead of conventional volumetric light projections. This approach reportedly boosts light efficiency by 20 times, resulting in faster and more accurate 3D printing. According to their paper, published in Nature Communications, HoloVAM successfully fabricated several millimeter-scale objects in under 60 seconds with fine details as small as 31 micrometers... They believe this new approach offers value for medical bioprinting applications, thanks to HoloVAM's use of "self-healing beams." These can generate and retain their shape when passing through materials, which is particularly valuable when 3D printing with cell-laden bio-resins and hydrogels.

Petawatt lasers have already allowed scientists to "manipulate materials in new ways, emulate the conditions inside planets, and even split atoms," reports Science magazine. "Now, accelerator physicists have matched that feat, producing petawatt pulses of electrons that could also have spectacular applications..." Described in a paper published Thursday in Physical Review Letters, the electron pulses last one-quadrillionth of a second but carry 100 kiloamps of current. "It's a supercool experiment," says Sergei Nagaitsev, an accelerator physicist at Brookhaven National Laboratory who was not involved in the work. Richard D'Arcy, a plasma accelerator physicist at the University of Oxford, adds, "It's not just an experimental demonstration of something interesting, it's a steppingstone on the way to megaamp beams." If achievable, those even more powerful beams might begin to perform extraordinary feats such as ripping particles out of empty space, he says... [A]mped-up lasers would open the way to, for example, probing chemical processes as they happen, says Sergei Nagaitsev [an accelerator physicist at Brookhaven National Laboratory who was not involved in the experiment]. "These are the easy pickings." An ultraintense electron pulse could also be used to generate plasmas like those seen in astrophysics, such as the jets of matter and radiation that shoot out of certain stellar explosions at near-light-speed. Researchers need only fire the electron beam into the right target. "This is a fantastic relativistic drill," Ferrario says. "The interaction of this with matter could be very interesting." Superintense electron bunches might someday even probe the nature of empty space. They produce a hugely intense electric field, so if one of them were to collide with an ultraintense laser pulse, which also contains a huge electric field, it would expose space to an incredibly strong electrical polarization, D'Arcy notes. If that field is strong enough, it should begin to rip particle-antiparticle pairs out of the vacuum, a phenomenon predicted by quantum physics but never observed. "You can access areas of particle physics that are inaccessible elsewhere," Darcy says. Thanks to Slashdot reader sciencehabit for sharing the article.

A malicious PyPi package effectively turned its users' systems "into an illicit network for facilitating bulk music downloads," writes The Hacker News. Though the package has been removed from PyPI, researchers at security platform Socket.dev say it enabled "coordinated, unauthorized music downloads from Deezer — a popular streaming service founded in France in 2007." Although automslc, which has been downloaded over 100,000 times, purports to offer music automation and metadata retrieval, it covertly bypasses Deezer's access restrictions... The package is designed to log into Deezer, harvest track metadata, request full-length streaming URLs, and download complete audio files in clear violation of Deezer's API terms... [I]t orchestrates a distributed piracy operation by leveraging both user-supplied and hardcoded Deezer credentials to create sessions with Deezer's API. This approach enables full access to track metadata and the decryption tokens required to generate full-length track URLs. Additionally, the package routinely communicates with a remote server... to update download statuses and submit metadata, thereby centralizing control and allowing the threat actor to monitor and coordinate the distributed downloading operation. In doing so, automslc exposes critical track details — including Deezer IDs, International Standard Recording Codes, track titles, and internal tokens like MD5_ORIGIN (a hash used in generating decryption URLs) — which, when collected en masse, can be used to reassemble full track URLs and facilitate unauthorized downloads... Even if a user pays for access to the service, the content is licensed, not owned. The automslc package circumvents licensing restrictions by enabling downloads and potential redistribution, which is outside the bounds of fair use...

Watch the "Blue Ghost" lunar lander attempt its moon landing. The actual landing is scheduled to happen at 3:34 a.m. Eastern time, according to CNN, while "The first images from the mission should be delivered about a half hour after..." Success is not guaranteed... [B]roadly speaking, about half of all lunar landing attempts have ended in failure. Jason Kim, Firefly's CEO, told CNN in December that his company's experience building rockets has given him a high degree of confidence in Blue Ghost's propulsion systems. "We're using (reaction control system) thrusters that we've built, developed in-house, that are designed by the same people that design our rocket engines. That reduces risk," Kim said. "All that gives us high confidence when we have people that do rocket engines really, really well — some of the best in the world." But the New York Times notes that Blue Ghost, built by Austin, Texas-based Firefly Aerospace, is just one of three robotic spacecraft "in space right now that are aiming to set down on the moon's surface." Blue Ghost has performed nearly perfectly. For the first 25 days, it circled Earth as the company turned on and checked the spacecraft's systems. It then fired its engine on a four-day journey toward the moon, entering orbit on February 13. The spacecraft's cameras have recorded close-up views of the moon's cratered surface... On the same SpaceX Falcon 9 rocket that launched Blue Ghost to orbit was Resilience, a lunar lander built by Ispace of Japan. The two missions are separate, but Ispace, seeking a cheaper ride to space, had asked SpaceX for a rideshare, that is, hitching a ride as a secondary payload... Although Resilience launched at the same time as Blue Ghost, it is taking a longer, more fuel-efficient route to the moon and is expected to enter orbit around the moon in early May. The third lunar lander heading to the moon is Athena (from Intuitive Machines), which launched Thursday on a SpaceX Falcon 9 rocket, "marking the first time humanity has had three lunar landers en route to the Moon at the same time," according to a statement from the company. Space.com notes that "To date, just one private spacecraft has ever landed successfully on the moon — Intuitive Machines' Odysseus, which did so in February 2024." Athena launched with several other spacecraft last night, including Odin, a scouting probe built by the asteroid-mining company Astroforge, and NASA's water-hunting Lunar Trailblazer. Lunar Trailblazer is also moon-bound, though it's headed for orbit rather than the surface...

Adafruit managing director Phillip Torrone (also long-time Slashdot reader ptorrone) shared an interesting blog post. They'd spotted a Reddit post "detailing how someone took a 27-year-old visual basic EXE file, fed it to Claude 3.7, and watched as it reverse-engineered the program and rewrote it in Python." It was an old Visual Basic 4 program they had written in 1997. Running a VB4 exe in 2024 can be a real yak-shaving compatibility nightmare, chasing down outdated DLLs and messy workarounds. So! OP decided to upload the exe to Claude 3.7 with this request: "Can you tell me how to get this file running? It'd be nice to convert it to Python."> Claude 3.7 analyzed the binary, extracted the VB 'tokens' (VB is not a fully-machine-code-compiled language which makes this task a lot easier than something from C/C++), identified UI elements, and even extracted sound files. Then, it generated a complete Python equivalent using Pygame. According to the author, the code worked on the first try and the entire process took less than five minutes... Torrone speculates on what this might mean. "Old business applications and games could be modernized without needing the original source code... Tools like Claude might make decompilation and software archaeology a lot easier: proprietary binaries from dead platforms could get a new life in open-source too." And maybe Archive.org could even add an LLM "to do this on the fly!"

NBC News reports that Utah could make history as America's first state to ban fluoride in public water systems — even though major medical associations supporting water fluoridation: If signed into law [by the governor], HB0081 would prevent any individual or political subdivision from adding fluoride "to water in or intended for public water systems..." A report published recently in JAMA Pediatrics found a statistically significant association between higher fluoride exposure and lower children's IQ scores — but the researchers did not suggest that fluoride should be removed from drinking water. According to the report's authors, most of the 74 studies they reviewed were low-quality and done in countries other than the United States, such as China, where fluoride levels tend to be much higher, the researchers noted. An Australian study published last year found no link between early childhood exposure to fluoride and negative cognitive neurodevelopment. Researchers actually found a slightly higher IQ in kids who consistently drank fluoridated water. The levels in Australia are consistent with U.S. recommendations. Major public health groups, including the American Academy of Pediatrics, the American Dental Association and the CDC — which says drinking fluoridated water keeps teeth strong and reduces cavities — support adding fluoride to water. The article notes that since 2010 over 150 U.S. towns or counties have voted to keep fluoride out of public water systems or to stop adding it to their water (according to the anti-fluoride group "Fluoride Action Network"). But this week the American Dental Association (representing 159,000 members) urged Utah's governor not to become " the only state to end this preventive health practice that has been in place for over three quarters of a century."

Long-time Slashdot reader MojoKid writes: AMD took the wraps of its next gen RDNA 4 consumer graphics architecture Friday, which was designed to enhance efficiency over the previous generation, while also optimizing performance for today's more taxing ray-traced gaming and AI workloads. RDNA 4 features next generation Ray Tracing engines, dedicated hardware for AI and ML workloads, better bandwidth utilization, and multimedia improvements for both gaming and content creation. AMD's 3rd generation Ray Accelerators in RDNA offer 2x the peak throughput of RDNA 3 and add support for a new feature called Oriented Bounding Boxes, that results in more efficient GPU utilization. 3rd Generation Matrix Accelerators are also present, which offer improved performance, along with support for 8-bit float data types, with structured sparsity. The first cards featuring RDNA 4, the Radeon RX 9070 and 9070 XT go on sale next week, with very competitive MSRPs below $600, and are expected to do battle with NVIDIA's GeForce RTX 5070-class GPUs The article calls it "a significant step forward" for AMD, adding that next week is "going to be very busy around here. NVIDIA is launching the final, previously announced member of the RTX 50 series and AMD will unleash the 9070 and 9070 XT."

"We need a license to allow us to make some of the basic functionality of Firefox possible," Mozilla explained Wednesday in a clarification a recent Terms of Use update. "Without it, we couldn't use information typed into Firefox, for example. It does NOT give us ownership of your data or a right to use it for anything other than what is described in the Privacy Notice." But Friday they went further, and revised those new Terms of Use "to more clearly reflect the limited scope of how Mozilla interacts with user data," according to a Mozilla blog post. More details from the Verge: The particular language that drew criticism was: "When you upload or input information through Firefox, you hereby grant us a nonexclusive, royalty-free, worldwide license to use that information to help you navigate, experience, and interact with online content as you indicate with your use of Firefox." That language has been removed. Now, the language in the terms says: "You give Mozilla the rights necessary to operate Firefox. This includes processing your data as we describe in the Firefox Privacy Notice. It also includes a nonexclusive, royalty-free, worldwide license for the purpose of doing as you request with the content you input in Firefox. This does not give Mozilla any ownership in that content...." Friday's post additionally provides some context about why the company has "stepped away from making blanket claims that 'We never sell your data.'" Mozilla says that "in some places, the LEGAL definition of 'sale of data' is broad and evolving," and that "the competing interpretations of do-not-sell requirements does leave many businesses uncertain about their exact obligations and whether or not they're considered to be 'selling data.'" Mozilla says that "there are a number of places where we collect and share some data with our partners" so that Firefox can be "commercially viable," but it adds that it spells those out in its privacy notice and works to strip data of potentially identifying information or share it in aggregate.

Hidden layers of rock below the surface of Mars "strongly suggest" the presence of an ancient ocean, according to an international team of scientists including researchers at Penn State. From the university's announcement: The new research offers the clearest evidence yet that the planet once contained a significant body of water and a more habitable environment for life, according to Benjamin Cardenas, assistant professor of geology at Penn State and co-author on the study. "We're finding places on Mars that used to look like ancient beaches and ancient river deltas," Cardenas said. "We found evidence for wind, waves, no shortage of sand — a proper, vacation-style beach." The Zhurong rover landed on Mars in 2021 in an area known as Utopia Planitia and sent back data on the geology of its surroundings in search of signs of ancient water or ice. Unlike other rovers, it came equipped with rover-penetrating radar, which allowed it to explore the planet's subsurface, using both low and high-frequency radar to penetrate the Martian soil and identify buried rock formations. By studying the underground sedimentary deposits, scientists are able to piece together a more complete picture of the red planet's history, Cardenas explained. When the team reviewed radar data, it revealed a similar layered structure to beaches on Earth: formations called "foreshore deposits" that slope downwards towards oceans and form when sediments are carried by tides and waves into a large body of water. "This stood out to us immediately because it suggests there were waves, which means there was a dynamic interface of air and water," Cardenas said. "When we look back at where the earliest life on Earth developed, it was in the interaction between oceans and land, so this is painting a picture of ancient habitable environments, capable of harboring conditions friendly toward microbial life." When the team compared the Martian data with radar images of coastal deposits on Earth, they found striking similarities, Cardenas said. The dip angles observed on Mars fell right within the range of those seen in coastal sedimentary deposits on Earth... The study also provided new information on the evolution of the Martian environment, suggesting that a life-friendly warm and wet period spanned potentially tens of millions of years. Mars "was evolving," Cardenas says in the announcement. "Rivers were flowing, sediment was moving, and land was being built and eroded. "This type of sedimentary geology can tell us what the landscape looked like, how they evolved, and, importantly, help us identify where we would want to look for past life." CNN notes that the research was published Monday in the journal Proceedings of the National Academy of Sciences.

Active since 1995, the Comprehensive Perl Archive Network (or CPAN) hosts 221,742 Perl modules written by 14,548 authors. This week they announced that the CPAN Security Group "was authorized by the CVE Program as a CVE Numbering Authority (CNA)" to assign and manage CVE vulnerability identifications for Perl and CPAN Modules. "This is great news!" posted Linux kernel maintainer Greg Kroah-Hartman on social media, saying the announcement came "Just in time for my talk about this very topic in a few weeks about how all open source projects should be doing this" at the Linux Foundation Member Summit in Napa, California. And Curl creator Daniel Stenberg posted "I'm with Greg Kroah-Hartman on this: all Open Source projects should become CNAs. Or team up with others to do it." (Also posting "Agreed" to the suggestion was Seth Larson, the Python Software Foundation's security developer-in-residence involved in their successful effort to become a CNA in 2023.) 444 CNAs have now partnered with the CVE Program, according to their official web site. The announcement from PerlMonks.org: Years ago, a few people decided during the Perl Toolchain Summit (PTS) that it would be a good idea to join forces, ideas and knowledge and start a group to monitor vulnerabilities in the complete Perl ecosystem from core to the smallest CPAN release. The goal was to follow legislation and CVE reports, and help authors in taking actions on not being vulnerable anymore. That group has grown stable over the past years and is now known as CPANSec. The group has several focus areas, and one of them is channeling CVE vulnerability issues. In that specific goal, a milestone has been reached: CPANSec has just been authorized as a CVE Numbering Authority (CNA) for Perl and modules on CPAN
