Iceland's Plan to Drill Into a Volcano to Test 'Limitless' Supercharged Geothermal Energy

Slashdot - Sun, 2024-10-27 18:34
In Iceland, "a volcanic system has awoken after an 800-year slumber," according to a multimedia CNN Special Report. "But in another part of Iceland, scientists and engineers are hoping to harness magma's immense power to solve the planet's biggest problem..." It all started in 2009 when Bjarni Pálsson, an engineer with Iceland's national power company, accidentally drilled into a magma chamber. "Armed with new technology and know-how, he is going back in..." The ambition of the geothermal experts and volcanologists that comprise the Krafla Magma Testbed is to convert the immense heat and pressure into a new "limitless" form of supercharged geothermal energy — a tantalizing prospect as the world struggles to end its relationship with planet-heating fossil fuels. "This has never been done before," said Hjalti Páll Ingólfsson, director of the Geothermal Research Cluster, which developed the project.... If all goes to plan, the first borehole will be completed in 2027 and will mark the first time anyone has ever implanted sensors directly into a magma chamber... If the first drilling experiment succeeds, the team will move onto the second borehole, due to be completed in 2029 — and this could be the global gamechanger. It's here the team will attempt to harness the intense heat of magma to produce a new kind of extreme geothermal energy, many times more powerful than conventional... If they succeed, the implications could reverberate around the world, Ingólfsson said. There are an estimated 800 million people living within roughly 60 miles of an active volcano. The report includes a map showing volcano sites around the earth where similar drilling could theoretically unleash the same intense magma-powered extreme geothermal energy. Iceland's plan is to drill down 1.2 miles — about 2 kilometers — into a magma chamber that's around 1,800 Fahrenheit (nearly 1,000 degrees Celsius). The engineering feat "won't be easy," the article acknowledges. "But as humans heat the planet at record speed with fossil fuel pollution, there is increasing pressure to perform moonshot feats of engineering to save us from ourselves."

SpaceX's Starship Super Heavy Booster Came Within 1 Second of Aborting Its First 'Catch' Landing

Slashdot - Sun, 2024-10-27 17:34
SpaceNews reports: SpaceX's Super Heavy booster came within a second of aborting a "catch" landing attempt on the latest Starship test flight, according to audio posted online, apparently inadvertently, by Elon Musk... In the audio, one person, not identified, described an issue with the Super Heavy landing burn where a "misconfigured" parameter meant that spin pressure, presuming in the Raptor engines in the booster, did not increase as expected. "We were one second away from that tripping and telling the rocket to abort and try to crash into the ground next to the tower," that person said. That scenario would "erroneously tell a healthy rocket to not try that catch...." The people on the audio note that there had been discussions of delaying the Flight 5 launch to provide additional time to check those parameters. "We were scared about the fact that we had 100 aborts that were not super-trivial," one person said... Another issue discussed in the audio... was a cover on a chine, a vertical structure on the booster, that came off as the vehicle went transonic during its descent. A SpaceX official said in the audio that having chine cover come off was something that they were worried about before launch... The person also started to discuss an issue with the engine plume during the landing burn, but the video stops at that point. The discussions appeared to involve planning for the next Starship test flight, Flight 6. SpaceX is moving ahead with preparations for the flight, moving the next Super Heavy booster to the launch site for testing. "Flight 6 is coming up soon!" Musk posted early Oct. 25.

Google is Developing AI that Can Take Over Chrome to Help You Buy Things, Do Research

Slashdot - Sun, 2024-10-27 16:34
This week Google-backed Anthropic announced its upgraded AI model Claude 3.5 Sonnet could "perform tasks like navigating web browsers, filling forms, and manipulating data." Now Google plans something similar for Chrome, reports 9to5Linux.com: According to The Information, Google is "developing artificial intelligence that takes over a person's web browser to complete tasks such as gathering research, purchasing a product or booking a flight." "Project Jarvis" — in a nod to J.A.R.V.I.S. in Iron Man — would operate in Google Chrome and is a consumer-facing (rather than enterprise) feature to "automate everyday, web-based tasks." The article doesn't specify whether this would be for mobile or desktop... Given a command/action, Jarvis works by taking "frequent screenshots of what's on their computer screen, and interpreting the shots before taking actions like clicking on a button or typing into a text field." The Information reports that Google "plans to preview the product, also known as a computer-using agent, as early as December alongside the release of its next flagship Gemini large language model, which would help power the product, two of the people said."

UK Nuclear Site's Clean-Up Costs Rise To £136 Billion

Slashdot - Sun, 2024-10-27 15:34
The cost of cleaning up the U.K.'s largest nuclear site, "is expected to spiral to £136 billion" (about $176 billion), according to the Guardian, creating tension with the country's public-spending watchdog. Projects to fix the state-owned buildings with hazardous and radioactive material "are running years late and over budget," the Guardian notes, with the National Audit Office suggesting spending at the Sellafield site has risen to more than £2.7 billion a year ($3.49 billion). Europe's most hazardous industrial site has previously been described by a former UK secretary of state as a "bottomless pit of hell, money and despair". The Guardian's Nuclear Leaks investigation in late 2023 revealed a string of cybersecurity problems at the site, as well as issues with its safety and workplace culture. The National Audit Office found that Sellafield was making slower-than-hoped progress on making the site safe and that three of its most hazardous storage sites pose an "intolerable risk". The site is a sprawling collection of buildings, many never designed to hold nuclear waste long-term, now in various states of disrepair. It stores and treats decades of nuclear waste from atomic power generation and weapons programmes, has taken waste from countries including Italy and Sweden, and is the world's largest store of plutonium. Sellafield is forecast to cost £136bn to decommission, which is £21.4bn or 18.8% higher than was forecast in 2019. Its buildings are expected to be finally torn down by 2125 and its nuclear waste buried deep underground at an undecided English location. The underground project's completion date has been delayed from 2040 to the 2050s at the earliest, meaning Sellafield will need to build more stores and manage waste for longer. Each decade of delay costs Sellafield between £500m and £760m, the National Audit Office said. Meanwhile, the government hopes to ramp up nuclear power generation, which will create more waste. "Plans to clean up three of its worst ponds — which contain hazardous nuclear sludge that must be painstakingly removed — are running six to 13 years later than forecast when the National Audit Office last drew up a report, in 2018... " "One pond, the Magnox swarf storage silo, is leaking 2,100 litres of contaminated water each day, the NAO found. The pond was due to be emptied by 2046 but this has slipped to 2059."

The Tech Secrets Behind Disneyland's 'Enchanted Tiki Room'

Slashdot - Sun, 2024-10-27 12:34
SFGate spills the secrets of Disneyland's "Enchanted Tiki Room" and its lifelike animatronic singing birds — Jose, Fritz, Michael and Pierre — "whose movements were perfectly synced with the audio track." "Beneath the room, the heartbeat of the attraction is a $1 million installation of electronics equipment, operated by a roll of 14-channel magnetic tape," the Orange County Register wrote upon its opening. "It is the same system which programs the U.S. military's polaris missile." That system also ran very hot. To keep guests from overheating, air conditioning was installed throughout the building, making the Tiki Room Disneyland's first attraction to be fully air conditioned... Or, as another article puts it, "While Disney did not delve into the speculative science of cryogenics to preserve his life, he did borrow the mechanical brain of a nuclear missile to simulate life, creating a new type of entertainment in the process." The article remembers how Wernher Von Braun became a technical advisor (and on-camera presenter) for three Disney-produced TV episodes about space travel — at the same time Von Braun was working as technical director for the U.S. Army rocket program that produced the world's first long-range guided ballistic missile, plus the first submarine-launched ballistic missile with its ground-breaking launch control mechanism: An important aspect of the Polaris launch system hinged on the fact that the conditions under which the missiles might be launched were constantly changing. Different underwater currents, temperatures, and flexing of the metal hull all contributed to the difficulty of a successful launch. In order to minimize human errors and to automate the sequence as much as possible, scientists developed an audio control system. A magnetic audio tape with a series of prerecorded cues precisely timed to account for the submarine's movement, controlled the launch machinery. This new technology, invented to deliver nuclear destruction, proved exactly what Disney needed for his wonderland developed for children. The article concludes that Disneyland engineering "transformed Von Braun's military technology" to the point today where "what was once controlled by the artificial brain of a nuclear missile is now run by the equivalent of a MacBook." SFGate delves deeper into the attraction's strange origins — and how it all came full circle 63 years later... At the intersection of Main Street and Adventureland, a restaurant called the Pavillion — now the Jolly Holiday — bridged the gap. Under one roof, it served food to Main Street guests on one side and Adventureland diners on the other. The inelegant transition created an eyesore that Walt despised... The need for the Tiki Cafe "appeared to be less about food and more about aesthetics," Ken Bruce writes in Before the Birds Sang Words , a comprehensive history of the attraction. In 1961, Walt gathered with park designers about the concept. The sketch made by legendary theme park designer John Hench was remarkably thorough, with much of its design incorporated into the final product... When Walt saw a plethora of birds in the sketch, he famously exclaimed, "We can't have birds in there ... because they'll poop in the food." Hench hurriedly ad-libbed that the birds would be mechanical, a concept that Walt adored... Although its powerful air conditioning may be its biggest draw today, many attractions you love owe their existence to the flock of singing birds. Disney engineers' work on the talking flora and fauna laid the foundation for much more complex Audio-Animatronics (a word that Walt Disney coined). Without Jose, Fritz, Michael and Pierre, there would be no Haunted Mansion, no Pirates of the Caribbean, no Rise of the Resistance. Next year, in celebration of Disneyland's 70th anniversary, the park will unveil one of its most sophisticated animatronics yet: Walt Disney himself. It will be the first time Walt appears in a Disney attraction anywhere in the world, completing a journey that started with a mechanical bird and ends with an immortal homage. Their article also reveals that a year after the Tiki Room opened, one of the birds was programmed to say "Come, there's an island there for you in Hawaii. Soaring birds of United Airlines fly there too!" Because Disneyland had signed a sponsorship deal with United Airlines...

'We Took on Google and They Were Forced to Pay Billions'

Slashdot - Sun, 2024-10-27 08:34
"Google essentially disappeared us from the internet," says the couple who created price-comparison site Foundem in 2006. Google's search results for "price comparison" and "comparison shopping" buried their site — for more than three years. Today the BBC looks at their 15-year legal battle, which culminated with a then record €2.4 billion fine (£2 billion or $2.6 billion) for Google, which was deemed to have abused its market dominance. The case has been hailed as a landmark moment in the global regulation of Big Tech. Google spent seven years fighting that verdict, issued in June 2017, but in September this year Europe's top court — the European Court of Justice — rejected its appeals. Speaking to Radio 4's The Bottom Line in their first interview since that final verdict, Shivaun and Adam explained that at first, they thought their website's faltering start had simply been a mistake. "We initially thought this was collateral damage, that we had been false positive detected as spam," says Shivaun, 55. "We just assumed we had to escalate to the right place and it would be overturned...." The couple sent Google numerous requests to have the restriction lifted but, more than two years later, nothing had changed and they said they received no response. Meanwhile, their website was "ranking completely normally" on other search engines, but that didn't really matter, according to Shivaun, as "everyone's using Google". The couple would later discover that their site was not the only one to have been put at a disadvantage by Google — by the time the tech giant was found guilty and fined in 2017 there were around 20 claimants, including Kelkoo, Trivago and Yelp... In its 2017 judgement, the European Commission found that Google had illegally promoted its own comparison shopping service in search results, whilst demoting those of competitors... "I guess it was unfortunate for Google that they did it to us," Shivaun says. "We've both been brought up maybe under the delusion that we can make a difference, and we really don't like bullies." Even Google's final defeat in the case last month did not spell the end for the couple. They believe Google's conduct remains anti-competitive and the EC is looking into it. In March this year, under its new Digital Markets Act, the commission opened an investigation into Google's parent company, Alphabet, over whether it continues to preference its own goods and services in search results... The Raffs are also pursuing a civil damages claim against Google, which is due to begin in the first half of 2026. But when, or if, a final victory comes for the couple it will likely be a Pyrrhic one — they were forced to close Foundem in 2016. A spokesperson for Google told the BBC the 2024 judgment from the European Court of Justice only relates to "how we showed product results from 2008-2017. The changes we made in 2017 to comply with the European Commission's Shopping decision have worked successfully for more than seven years, generating billions of clicks for more than 800 comparison shopping services. "For this reason, we continue to strongly contest the claims made by Foundem and will do so when the case is considered by the courts."

Did Capturing Carbon from the Air Just Get Easier?

Slashdot - Sun, 2024-10-27 02:34
"We passed Berkeley air — just outdoor air — into the material to see how it would perform," says U.C. Berkeley chemistry professor Omar Yaghi, "and it was beautiful. "It cleaned the air entirely of CO2," Yaghi says in an announcement from the university. "Everything." SFGate calls it "a discovery that could help potentially mitigate the effects of climate change..." Yaghi's lab has worked on carbon capture since the 1990s and began work on these crystalline structures in 2005. The innovative substance has lots of tiny holes, making it "great for storing gases or liquids, much like a sponge holds water," Yaghi said... While it could take one to two years for the powder to be usable in large-scale applications, Yaghi co-founded Atoco, an Irvine company, to commercialize his research and expand it beyond just carbon capture and storage. "Capturing carbon from the air just got easier," says the headline on the anouncement from the university, which explains why this technology is crucial: [T]oday's carbon capture technologies work well only for concentrated sources of carbon, such as power plant exhaust. The same methods cannot efficiently capture carbon dioxide from ambient air, where concentrations are hundreds of times lower than in flue gases. Yet direct air capture, or DAC, is being counted on to reverse the rise of CO2 levels, which have reached 426 parts per million, 50% higher than levels before the Industrial Revolution. Without it, according to the Intergovernmental Panel on Climate Change, we won't reach humanity's goal of limiting warming to 1.5 degreesC (2.7 degreesF) above preexisting global averages. A new type of absorbing material developed by chemists at the University of California, Berkeley, could help get the world to negative emissions... According to Yaghi, the new material could be substituted easily into carbon capture systems already deployed or being piloted to remove CO2 from refinery emissions and capture atmospheric CO2 for storage underground. UC Berkeley graduate student Zihui Zhou, the paper's first author, said that a mere 200 grams of the material, a bit less than half a pound, can take up as much CO2 in a year — 20 kilograms (44 pounds) — as a tree. Their research was published this week in the journal Nature. And it's also interesting that they're using AI, according to the university's announcement: Yaghi is optimistic that artificial intelligence can help speed up the design of even better COFs and MOFs for carbon capture or other purposes, specifically by identifying the chemical conditions required to synthesize their crystalline structures. He is scientific director of a research center at UC Berkeley, the Bakar Institute of Digital Materials for the Planet (BIDMaP), which employs AI to develop cost-efficient, easily deployable versions of MOFs and COFs to help limit and address the impacts of climate change. "We're very, very excited about blending AI with the chemistry that we've been doing," he said. Another potential use could be for harvesting water from desert air for drinking water, Yaghi told SFGate. But he seems very focused specifically on carbon capture. "Another thing is that we need a strong determination among officials and industries to make carbon capture a high priority. Things have to change, but I believe that direct carbon capture from air is very doable."

One Argument Why Data Caps Are Not a Problem

Slashdot - Sun, 2024-10-27 00:34
NoWayNoShapeNoForm writes: OpenVault believes that data caps on broadband are not a problem because most people do not exceed their existing data caps. OpenVault contends that people that do exceed their broadband data caps are simply being forgetful — leaving a streaming device on 24x7, or deploying unsecure WiFi access points, or reselling their service within an apartment building. Yes, there may be some ISPs that have older networks that they have not upgraded. Or maybe they are unable to increase network capacity in "the middle mile" of their networks, but the Covid pandemic certainly encouraged many ISPs to upgrade their networks and capacity while many ISPs that had broadband data caps ended that feature. Perhaps the biggest problem, according to OpenVault, is that most broadband users do not really have any idea how much bandwidth they "consume" every month. If Internet access is a service that people want to treat as a "utility", then you have to ask, Would they keep the water running after finishing their shower? In the article Ookla's VP of Smart Communities adds that "Scrolling through social media feeds for hours can 'push' hundreds of videos to the user, many of which may be of no interest — they just start running." So the main driver for usage-based billing wasn't to increase revenue, OpenVault CEO Mark Trudeau tells the site, but to "balance the network a little more..." (Though he then also adds that sometimes a subscriber could also be reselling broadband service in their apartment building, "And that's not even legal.") "If one or two customers on a given node is causing issues for 300 others, where those 300 are not getting the service that they paid for, then that's a problem right?" he said. Having said that, the article also points out that "Many major fiber providers, like AT&T, Frontier, Google Fiber and Verizon Fios, don't have data caps at all."

Singapore Approves 2,600-Mile Undersea Cable to Import Solar Energy from Australia

Slashdot - Sat, 2024-10-26 23:34
"The world's largest renewable energy and transmission project has received key approval from government officials," reports New Atlas. Solar power from Australia will be carried 2,672 miles (4,300 kilometers) to Singapore over undersea cables in what's being called "the Australia-Asia Power Link project." Reuters reports that SunCable "aims to produce 6 gigawatts of electricity at a vast solar farm in Northern Australia and ship about a third of that to Singapore via undersea cable." More from New Atlas: [The project] will start by constructing a mammoth solar farm in Australia's Northern Territory to transmit around-the-clock clean power to [the Australian city] Darwin, and also export "reliable, cost-competitive renewable energy" to Singapore... with a clean energy generation capacity of up to 10 gigawatts, plus utility scale onsite storage. [The recently-obtained environmental approval] also green lights an 800-km (~500-mile) overhead transmission line between the solar precinct and Murrumujuk near Darwin... If all of the dominoes line up perfectly, supply of the first clean electricity is estimated to start in the early 2030s. An overview graphic on the project page shows that the eventual end game for the Powell Creek development appears to be the generation of up to 20 GW of peak solar power and have some 36-42 GWh of battery storage on site.

Researchers Discover Flaws In Five End-to-End Encrypted Cloud Services

Slashdot - Sat, 2024-10-26 22:34
SC World reports: Several major end-to-end encrypted cloud storage services contain cryptographic flaws that could lead to loss of confidentiality, file tampering, file injection and more, researchers from ETH Zurich said in a paper published this month. The five cloud services studied offer end-to-end encryption (E2EE), intended to ensure files can not be read or edited by anyone other than the uploader, meaning not even the cloud storage provider can access the files. However, ETH Zurich researchers Jonas Hofmann and Kien Tuong Truong, who presented their findings at the ACM Conference on Computer and Communications Security (CCS) last week, found serious flaws in four out of the five services that could effectively bypass the security benefits provided by E2EE by enabling an attacker who managed to compromise a cloud server to access, tamper with or inject files. The E2EE cloud storage services studied were Sync, pCloud, Seafile, Icedrive and Tresorit, which have a collective total of about 22 million users. Tresorit had the fewest vulnerabilities, which could enable some metadata tampering and use of non-authentic keys when sharing files. The other four services were found to have more severe flaws posing a greater risk to file confidentiality and integrity. BleepingComputer reports that Sync is "fast-tracking fixes," while Seafile "promised to patch the protocol downgrade problem on a future upgrade." And SC World does note that all 10 of the tested exploits "would require the attacker to have already gained control of a server with the ability to read, modify and inject data. "The authors wrote that they consider this to be a realistic threat model for E2EE services, as these services are meant to protect files even if such a compromise was to occur."

Researchers Develop New Lithium Extraction Method With 'Nearly Double the Performance'

Slashdot - Sat, 2024-10-26 19:34
PV Magazine reports: Researchers in Australia and China have developed an innovative technology enabling direct lithium extraction from difficult-to-process sources like saltwater, which they say represents a substantial portion of the world's lithium potential. Until now, up to 75% of the world's lithium-rich saltwater sources have remained untapped because of technical limitations, but given predictions that global lithium supply could fall short of demand as early as 2025, the researchers believe they have a game-changing solution. Their technology is a type of nanofiltration system that uses ethylenediaminetetraacetic acid, or EDTA, as a chelating agent to selectively separate lithium from other minerals, especially magnesium, which is often present in brines and difficult to remove. "With some predicting global lithium supply could fall short of demand as early as 2025, the innovative technology sets a new standard in lithium processing," writes SciTechDaily: The work, co-led by Dr Zhikao Li, from the Monash Suzhou Research Institute and the Department of Chemical and Biological Engineering, and Professor Xiwang Zhang from the University of Queensland, promises to meet the surging demand for lithium and paves the way for more sustainable and efficient extraction practices... "Our technology achieves 90 percent lithium recovery, nearly double the performance of traditional methods, while dramatically reducing the time required for extraction from years to mere weeks," Dr. Li said. The technology also turns leftover magnesium into a valuable, high-quality product that can be sold, reducing waste and its impact on the environment. Beyond its advanced efficiency, the EALNF system brings innovation to address major environmental concerns associated with lithium extraction. Unlike conventional methods that deplete vital water resources in arid regions, the technology produces freshwater as a by-product. Dr Li said the system was flexible and ready for large-scale use, meaning it can quickly expand from testing to full industrial operations. "This breakthrough is crucial for avoiding a future lithium shortage, making it possible to access lithium from hard-to-reach sources and helping power the shift to clean energy." "Our scalable process minimizes environmental impact while maximizing resource utilization," according to the researchers' article in Nature Sustainability, "thereby catalysing the shift toward a more sustainable future."

Egyptian Blogger/Developer Still Held in Prison 28 Days After His Release Date

Slashdot - Sat, 2024-10-26 18:34
In 2004 Alaa Abd El Fattah answered questions from Slashdot's readers about organizing the first-ever Linux installfest in Egypt. In 2014 he was arrested for organizing poltical protests without requesting authorization, according to Wikipedia, and then released on bail — but then sentenced to five years in prison upon retrial. He was released in late March of 2019, but then re-arrested again in September by the National Security Agency, convicted of "spreading fake news" and jailed for five years... Wikipedia describes Abd El-Fattah as an "Egyptian-British blogger, software developer and a political activist" who has been "active in developing Arabic-language versions of software and platforms." But this week an EFF blog post noticed that his released date had recently passed — and yet he was still in prison: It's been 28 days since September 29, the day that should have seen British-Egyptian blogger, coder, and activist Alaa Abd El Fattah walk free. Egyptian authorities refused to release him at the end of his sentence, in contradiction of the country's own Criminal Procedure Code, which requires that time served in pretrial detention count toward a prison sentence. [Human Rights Watch says Egyptian authorities are refusing to count more than two years of pretrial detention toward his time served. Amnesty International has also called for his release.] In the days since, Alaa's family has been able to secure meetings with high-level British officials, including Foreign Secretary David Lammy, but as of yet, the Egyptian government still has not released Alaa... Alaa deserves to finally return to his family, now in the UK, and to be reunited with his son, Khaled, who is now a teenager. We urge EFF supporters in the UK to write to their MP to place pressure on the UK's Labour government to use their power to push for Alaa's release. Last month the EFF wrote:: Over 20 years ago Alaa began using his technical skills to connect coders and technologists in the Middle East to build online communities where people could share opinions and speak freely and privately. The role he played in using technology to amplify the messages of his fellow Egyptians — as well as his own participation in the uprising in Tahrir Square — made him a prominent global voice during the Arab Spring, and a target for the country's successive repressive regimes, which have used antiterrorism laws to silence critics by throwing them in jail and depriving them of due process and other basic human rights. Alaa is a symbol for the principle of free speech in a region of the world where speaking out for justice and human rights is dangerous and using the power of technology to build community is criminalized...

DTrace for Linux Comes to Gentoo

Slashdot - Sat, 2024-10-26 17:34
It was originally created back in 2005 by Sun Microsystems for its proprietary Solaris Unix systems, "for troubleshooting kernel and application problems on production systems in real time," explains Wikipedia. "DTrace can be used to get a global overview of a running system, such as the amount of memory, CPU time, filesystem and network resources used by the active processes," explains its Wikipedia entry. But this week, Gentoo announced: The real, mythical DTrace comes to Gentoo! Need to dynamically trace your kernel or userspace programs, with rainbows, ponies, and unicorns — and all entirely safely and in production?! Gentoo is now ready for that! Just emerge dev-debug/dtrace and you're all set. All required kernel options are already enabled in the newest stable Gentoo distribution kernel... Documentation? Sure, there's lots of it. You can start with our DTrace wiki page, the DTrace for Linux page on GitHub, or the original documentation for Illumos. Enjoy! Thanks to Heraklit (Slashdot reader #29,346) for sharing the news.

Password Manager Bitwarden Makes Changes to Address Concerns Over Open Source Licensing

Slashdot - Sat, 2024-10-26 16:34
Bitwarden describes itself as an "open source password manager for business." But it also made a change its build requirement which led to an issue on the project's GitHub page titled "Desktop version 2024.10.0 is no longer free software." In the week that followed Bitwarden's official account on X.com promised a fix was coming. "It seems a packaging bug was misunderstood as something more, and the team plans to resolve it. Bitwarden remains committed to the open source licensing model in place for years, along with retaining a fully featured free version for individual users." And Thursday Bitwarden followed through with new changes to address the concerns. The Register reports the whole episode started because of a new build requirement added in a pull request a couple of weeks ago titled "Introduce SDK client." This SDK is required to compile the software from source — either the Bitwarden server or any of its client applications... [But the changed license had warned "You may not use this SDK to develop applications for use with software other than Bitwarden (including non-compatible implementations of Bitwarden) or to develop another SDK."] Phoronix picks up the story: The issue of this effectively not making the Bitwarden client free software was raised in this GitHub issue... Bitwarden founder and CTO Kyle Spearrin has commented on the ticket... "Being able to build the app as you are trying to do here is an issue we plan to resolve and is merely a bug." The ticket was subsequently locked and limited to collaborators. And Thursday it was Bitwarden founder and CTO Kyle Spearrin who again re-appeared in the Issue — first thanking the user who had highlighted the concerns. "We have made some adjustments to how the SDK code is organized and packaged to allow you to build and run the app with only GPL/OSI licenses included." The sdk-internal package references in the clients now come from a new sdk-internal repository, which follows the licensing model we have historically used for all of our clients (see LICENSE_FAQ.md for more info). The sdk-internal reference only uses GPL licenses at this time. If the reference were to include Bitwarden License code in the future, we will provide a way to produce multiple build variants of the client, similar to what we do with web vault client builds. The original sdk repository will be renamed to sdk-secrets, and retains its existing Bitwarden SDK License structure for our Secrets Manager business products. The sdk-secrets repository and packages will no longer be referenced from the client apps, since that code is not used there.

Delta Sues CrowdStrike Over Software Update That Prompted Mass Flight Disruptions

Slashdot - Sat, 2024-10-26 15:00
An anonymous reader quotes a report from Reuters: Delta Air Lines on Friday sued cybersecurity firm CrowdStrike in a Georgia state court after a global outage in July caused mass flight cancellations, disrupted travel plans of 1.3 million customers and cost the carrier more than $500 million. Delta's lawsuit filed in Fulton County Superior Court called the faulty software update from CrowdStrike "catastrophic" and said the firm "forced untested and faulty updates to its customers, causing more than 8.5 million Microsoft Windows-based computers around the world to crash." [...] Delta, which has purchased CrowdStrike products since 2022, said the outage forced it to cancel 7,000 flights, impacting 1.3 million passengers over five days. "If CrowdStrike had tested the faulty update on even one computer before deployment, the computer would have crashed," Delta's lawsuit says. "Because the faulty update could not be removed remotely, CrowdStrike crippled Delta's business and created immense delays for Delta customers." Delta said that as part of its IT-planning and infrastructure, it has invested billions of dollars "in licensing and building some of the best technology solutions in the airline industry."

NASA Is Developing a Mars Helicopter That Could Land Itself From Orbit

Slashdot - Sat, 2024-10-26 12:00
Longtime Slashdot reader MattSparkes writes: NASA is working on plans to send another, much larger helicopter to Mars than Ingenuity. The "Chopper" craft would land itself after "screaming into" the planet's atmosphere at speed, before covering several kilometers a day while carrying scientific equipment. It would probably be the most graceful arrival on the red planet of any lander yet.
