Delta Seeks Damages From CrowdStrike, Microsoft After Outage

Par : BeauHD
30 juillet 2024 à 10:00
An anonymous reader quotes a report from CNBC: Delta Air Lines has hired prominent attorney David Boies to seek damages from CrowdStrike and Microsoft following an outage this month that caused millions of computers to crash, leading to thousands of flight cancellations. CrowdStrike shares fell as much as 5% in extended trading on Monday after CNBC's Phil Lebeau reported on Delta's hiring of Boies, chairman of Boies Schiller Flexner. Microsoft was little changed. [...] While no suit has been filed, Delta plans to seek compensation from Microsoft and CrowdStrike, Lebeau reported. The outages cost Delta an estimated $350 million to $500 million. Delta is dealing with over 176,000 refund or reimbursement requests after almost 7,000 flights were canceled. Boies is known for representing the U.S. government in its landmark antitrust case against Microsoft and for helping win a decision that overturned California's ban on gay marriage. He also worked with Harvey Weinstein, the imprisoned former Hollywood mogul, and Theranos founder Elizabeth Holmes, who is currently serving a prison sentence for defrauding investors. Insurance startup Parametrix estimated that the CrowdStrike incident resulted in a total loss of $5.4 billion for Fortune 500 companies, not including Microsoft.

China Ponders Creating a National 'Cyberspace ID'

Par : BeauHD
30 juillet 2024 à 07:00
China has proposed issuing "cyberspace IDs" to its citizens in order to protect their personal information, regulate the public service for authentication of cyberspace IDs, and accelerate the implementation of the trusted online identity strategy. The Register reports: The ID will take two forms: one as a series of letter and numbers, and the other as an online credential. Both will correspond to the citizen's real-life identity, but with no details in plaintext -- presumably encryption will be applied. A government national service platform will be responsible for authenticating and issuing the cyberspace IDs. The draft comes from the Ministry of Public Security and the Cyberspace Administration of China (CAC). It clarifies that the ID will be voluntary -- for now -- and eliminate the need for citizens to provide their real-life personal information to internet service providers (ISPs). Those under the age of fourteen would need parental consent to apply. China is one of the few countries in the world that requires citizens to use their real names on the internet. [...] Relying instead on a national ID means "the excessive collection and retention of citizens' personal information by internet service providers will be prevented and minimized," reasoned Beijing. "Without the separate consent of a natural person, an internet platform may not process or provide relevant data and information to the outside without authorization, except as otherwise provided by laws and administrative regulations," reads the draft.

Low-Income Homes Drop Internet Service After Congress Kills Discount Program

Par : BeauHD
30 juillet 2024 à 05:00
An anonymous reader quotes a report from Ars Technica: The death of the US government's Affordable Connectivity Program (ACP) is starting to result in disconnection of Internet service for Americans with low incomes. On Friday, Charter Communications reported a net loss of 154,000 Internet subscribers that it said was mostly driven by customers canceling after losing the federal discount. About 100,000 of those subscribers were reportedly getting the discount, which in some cases made Internet service free to the consumer. The $30 monthly broadband discounts provided by the ACP ended in May after Congress failed to allocate more funding. The Biden administration requested (PDF) $6 billion to fund the ACP through December 2024, but Republicans called the program "wasteful." Republican lawmakers' main complaint was that most of the ACP money went to households that already had broadband before the subsidy was created. FCC Chairwoman Jessica Rosenworcel warned that killing the discounts would reduce Internet access, saying (PDF) an FCC survey found that 77 percent of participating households would change their plan or drop Internet service entirely once the discounts expired. Charter's Q2 2024 earnings report provides some of the first evidence of users dropping Internet service after losing the discount. "Second quarter residential Internet customers decreased by 154,000, largely driven by the end of the FCC's Affordable Connectivity Program subsidies in the second quarter, compared to an increase of 70,000 during the second quarter of 2023," Charter said. Across all ISPs, there were 23 million US households enrolled in the ACP. Research released in January 2024 found that Charter was serving over 4 million ACP recipients and that up to 300,000 of those Charter customers would be "at risk" of dropping Internet service if the discounts expired. Given that ACP recipients must meet low-income eligibility requirements, losing the discounts could put a strain on their overall finances even if they choose to keep paying for Internet service. [...] Light Reading reported that Charter attributed about 100,000 of the 154,000 customer losses to the ACP shutdown. Charter said it retained most of its ACP subscribers so far, but that low-income households might not be able to continue paying for Internet service without a new subsidy for much longer.

30 juillet 2024 à 02:42
In an incident report today, DigiCert says it discovered that some CNAME-based validations did not include the required underscore prefix, affecting about 0.4% of their domain validations. According to CA/Browser Forum (CABF) rules, certificates with validation issues must be revoked within 24 hours, prompting DigiCert to take immediate action. DigiCert says impacted customers "have been notified." New submitter jdastrup first shared the news, writing: Due to a mistake going back years that has recently been discovered, DigiCert is required by the CABF to revoke any certificate that used the improper Domain Control Validation (DCV) CNAME record in 24 hours. This could literally be thousands of SSL certs. This could take a lot of time and potentially cause outages worldwide starting July 30 at 19:30 UTC. Be prepared for a long night of cert renewals. DigiCert support line is completely jammed.

Mike McQuaid on 15 Years of Homebrew and Protecting Open-Source Maintainers

Par : BeauHD
30 juillet 2024 à 01:00
Despite multiple methods available across major operating systems for installing and updating applications, there remains "no real clear answer to 'which is best,'" reports The Next Web. Each system faces unique challenges such as outdated packages, high fees, and policy restrictions. Enter Homebrew. "Initially created as an option for developers to keep the dependencies they often need for developing, testing, and running their work, Homebrew has grown to be so much more in its 15-year history." Created in 2009, Homebrew has become a leading solution for macOS, integrating with MDM tools through its enterprise-focused extension, Workbrew, to balance user freedom with corporate security needs, while maintaining its open-source roots under the guidance of Mike McQuaid. In an interview with The Next Web's Chris Chinchilla, project leader Mike McQuaid talks about the challenges and responsibilities of maintaining one of the world's largest open-source projects: As with anything that attracts plenty of use and attention, Homebrew also attracts a lot of mixed and extreme opinions, and processing and filtering those requires a tough outlook, something that Mike has spoken about in numerous interviews and at conferences. "As a large project, you get a lot of hate from people. Either people are just frustrated because they hit a bug or because you changed something, and they didn't read the release notes, and now something's broken," Mike says when I ask him about how he copes with the constant influx of communication. "There are a lot of entitled, noisy users in open source who contribute very little and like to shout at people and make them feel bad. One of my strengths is that I have very little time for those people, and I just insta-block them or close their issues." More crucially, an open-source project is often managed and maintained by a group of people. Homebrew has several dozen maintainers and nearly one thousand total contributors. Mike explains that all of these people also deserve to be treated with respect by users, "I'm also super protective of my maintainers, and I don't want them to be treated that way either." But despite these features and its widespread use, one area Homebrew has always lacked is the ability to work well with teams of users. This is where Workbrew, a company Mike founded with two other Homebrew maintainers, steps in. [...] Workbrew ties together various Homebrew features with custom glue to create a workflow for setting up and maintaining Mac machines. It adds new features that core Homebrew maintainers had no interest in adding, such as admin and reporting dashboards for a computing fleet, while bringing more general improvements to the core project. Bearing in mind Mike's motivation to keep Homebrew in the "traditional open source" model, I asked him how he intended to keep the needs of the project and the business separated and satisfied. "We've seen a lot of churn in the last few years from companies that made licensing decisions five or ten years ago, which have now changed quite dramatically and have generated quite a lot of community backlash," Mike said. "I'm very sensitive to that, and I am a little bit of an open-source purist in that I still consider the open-source initiative's definition of open source to be what open source means. If you don't comply with that, then you can be another thing, but I think you're probably not open source." And regarding keeping his and his co-founder's dual roles separated, Mike states, "I'm the CTO and co-founder of Workbrew, and I'm the project leader of Homebrew. The project leader with Homebrew is an elected position." Every year, the maintainers and the community elect a candidate. "But then, with the Homebrew maintainers working with us on Workbrew, one of the things I say is that when we're working on Workbrew, I'm your boss now, but when we work on Homebrew, I'm not your boss," Mike adds. "If you think I'm saying something and it's a bad idea, you tell me it's a bad idea, right?" The company is keeping its early progress in a private beta for now, but you can expect an announcement soon. As for what's happening for Homebrew? Well, in the best "open source" way, that's up to the community and always will be.

29 juillet 2024 à 23:40
According to Reuters, Hewlett Packard Enterprise (HPE) is expected to secure unconditional EU antitrust approval for its $14 billion acquisition of networking gear maker Juniper Networks. From the report: HPE announced the deal in January, underscoring the rush by companies to upgrade and develop new products amid a sharp rise in artificial intelligence-driven services. The European Commission, which is scheduled to decide on the deal by Aug. 1, declined to comment. HPE was expected to underline the power of market leader and Juniper rival Cisco to allay any possible European Union competition concerns, other people with direct knowledge of the matter had previously told Reuters. The deal is also being assessed by Britain's antitrust enforcer, with a decision due on Aug. 14.

From Sci-Fi To State Law: California's Plan To Prevent AI Catastrophe

Par : BeauHD
29 juillet 2024 à 23:00
An anonymous reader quotes a report from Ars Technica: California's "Safe and Secure Innovation for Frontier Artificial Intelligence Models Act" (a.k.a. SB-1047) has led to a flurry of headlines and debate concerning the overall "safety" of large artificial intelligence models. But critics are concerned that the bill's overblown focus on existential threats by future AI models could severely limit research and development for more prosaic, non-threatening AI uses today. SB-1047, introduced by State Senator Scott Wiener, passed the California Senate in May with a 32-1 vote and seems well positioned for a final vote in the State Assembly in August. The text of the bill requires companies behind sufficiently large AI models (currently set at $100 million in training costs and the rough computing power implied by those costs today) to put testing procedures and systems in place to prevent and respond to "safety incidents." The bill lays out a legalistic definition of those safety incidents that in turn focuses on defining a set of "critical harms" that an AI system might enable. That includes harms leading to "mass casualties or at least $500 million of damage," such as "the creation or use of chemical, biological, radiological, or nuclear weapon" (hello, Skynet?) or "precise instructions for conducting a cyberattack... on critical infrastructure." The bill also alludes to "other grave harms to public safety and security that are of comparable severity" to those laid out explicitly. An AI model's creator can't be held liable for harm caused through the sharing of "publicly accessible" information from outside the model -- simply asking an LLM to summarize The Anarchist's Cookbook probably wouldn't put it in violation of the law, for instance. Instead, the bill seems most concerned with future AIs that could come up with "novel threats to public safety and security." More than a human using an AI to brainstorm harmful ideas, SB-1047 focuses on the idea of an AI "autonomously engaging in behavior other than at the request of a user" while acting "with limited human oversight, intervention, or supervision." To prevent this straight-out-of-science-fiction eventuality, anyone training a sufficiently large model must "implement the capability to promptly enact a full shutdown" and have policies in place for when such a shutdown would be enacted, among other precautions and tests. The bill also focuses at points on AI actions that would require "intent, recklessness, or gross negligence" if performed by a human, suggesting a degree of agency that does not exist in today's large language models. The bill's supporters include AI experts Geoffrey Hinton and Yoshua Bengio, who believe the bill is a necessary precaution against potential catastrophic AI risks. Bill critics include tech policy expert Nirit Weiss-Blatt and AI community voice Daniel Jeffries. They argue that the bill is based on science fiction fears and could harm technological advancement. Ars Technica contributor Timothy Lee and Meta's Yann LeCun say that the bill's regulations could hinder "open weight" AI models and innovation in AI research. Instead, some experts suggest a better approach would be to focus on regulating harmful AI applications rather than the technology itself -- for example, outlawing nonconsensual deepfake pornography and improving AI safety research.

One Question Stopped a Deepfake Scam Attempt At Ferrari

Par : BeauHD
29 juillet 2024 à 22:23
"Deepfake scams are becoming more prolific and their quality will only improve over time," writes longtime Slashdot reader smooth wombat. "However, one question can stop them dead in their tracks. Such was the case with Ferrari earlier this month when a suspicious executive saved the company from being the latest victim." From a report: It all began with a series of WhatsApp messages from someone posing as Ferrari's CEO [Benedetto Vigna]. The messages, seeking urgent help with a supposed classified acquisition, came from a different number but featured a profile picture of Vigna standing in front of the Ferrari emblem. As reported by Bloomberg, one of the messages read: "Hey, did you hear about the big acquisition we're planning? I could need your help." The scammer continued, "Be ready to sign the Non-Disclosure Agreement our lawyer will send you ASAP." The message concluded with a sense of urgency: "Italy's market regulator and Milan stock exchange have already been informed. Maintain utmost discretion." Following the text messages, the executive received a phone call featuring a convincing impersonation of Vigna's voice, complete with the CEO's signature southern Italian accent. The caller claimed to be using a different number due to the sensitive nature of the matter and then requested the executive execute an "unspecified currency hedge transaction." The oddball money request, coupled with some "slight mechanical intonations" during the call, raised red flags for the Ferrari executive. He retorted, "Sorry, Benedetto, but I need to verify your identity," and quizzed the CEO on a book he had recommended days earlier. Unsurprisingly, the impersonator flubbed the answer and ended the call in a hurry.

Apple In Talks To Bring Ads To Apple TV+

29 juillet 2024 à 21:30
Following in the footsteps of competitors Netflix and Disney+, Apple is reportedly working on bringing advertisements to Apple TV+ through an ad-supported tier. MacRumors reports: Apple has apparently been in discussions with the UK's Broadcaster's Audience Research Board (BARB) to explore the necessary data collection techniques for monitoring advertising results. Currently, BARB provides viewing statistics for major UK networks including the BBC, ITV, Channel 4, and Sky, as well as Apple TV+ programming. While BARB already monitors viewing time for Apple TV+ content, additional techniques are required to track advertising metrics accurately. This data is vital for advertisers to assess the reach and impact of their campaigns on the platform. In addition to the UK, Apple has also reportedly held similar discussions with ratings organizations in the United States. Apple has already included limited advertising in its live sports events, such as last year's Major League Soccer coverage, where ads were incorporated even for Season Pass holders. It is also notable that in March Apple hired Joseph Cady, a former advertising executive from NBCUniversal, to bolster its video advertising team.

Sam Altman Issues Call To Arms To Ensure 'Democratic AI' Will Defeat 'Authoritarian AI'

Par : BeauHD
29 juillet 2024 à 20:50
In a Washington Post op-ed last week, OpenAI CEO Sam Altman emphasized the urgent need for the U.S. and its allies to lead the development of "democratic AI" to counter the rise of "authoritarian AI" models (source paywalled; alternative source). He outlined four key steps for this effort: enhancing security measures, expanding AI infrastructure, creating commercial diplomacy policies, and establishing global norms for AI development and deployment. Fortune reports: He noted that Russian President Vladimir Putin has said the winner of the AI race will "become the ruler of the world" and that China plans to lead the world in AI by 2030. Not only will such regimes use AI to perpetuate their own hold on power, but they can also use the technology to threaten others, Altman warned. If authoritarians grab the lead in AI, they could force companies in the U.S. and elsewhere to share user data and use the technology to develop next-generation cyberweapons, he said. [...] "While identifying the right decision-making body is important, the bottom line is that democratic AI has a lead over authoritarian AI because our political system has empowered U.S. companies, entrepreneurs and academics to research, innovate and build," Altman said. Unless the democratic vision prevails, the world won't be cause to maximize the technology's benefits and minimize its risks, he added. "If we want a more democratic world, history tells us our only choice is to develop an AI strategy that will help create it, and that the nations and technologists who have a lead have a responsibility to make that choice -- now."

French Internet Lines Cut In Latest Attack During Olympics

Par : BeauHD
29 juillet 2024 à 20:10
An anonymous reader quotes a report from Bloomberg: A number of fiber optic cables carrying broadband service across France were cut overnight in the latest attack on the country's infrastructure during the Olympic Games. Connections serving Paris, which is hosting the Olympic Games this week, and the games themselves weren't affected, a spokesman for Olympics telecom partner, Orange SA, said. Still, this is the second sabotage of French infrastructure in the past few days as the world converges on the capital. Coordinated fires on French rail lines disrupted trains ahead of the opening ceremony on Friday. The fiber cables were cut in nine departments overall including: Ardeche, Aude, Bouches-du-Rhone, Drome, Herault, Vaucluse, Marne, Meuse and Oise, the French Telecom Federation said. SFR said its network was vandalized between 1 a.m. and 3 a.m. Paris time, and teams are working on repairs, a spokesman for the French phone company said. The carrier is using alternative routes to serve customers, though redirecting the traffic might lead to slower speeds. Other carriers, including Iliad SA's Free and Netalis, also said they were impacted in social media posts. Netalis Chief Executive Officer Nicolas Guillaume said that the telecom company had successfully moved traffic to backup networks early on Monday. French cloud provider OVHcloud is also working to reroute traffic after the incident, which had caused slower performance on connections between Europe and Asia Pacific, a spokesman said. "We advocate for France reinforcing criminal sanctions for vandalism on telecom infrastructure, which should be put at the same level as vandalism on energy infrastructure," said Romain Bonenfant, head of the French Telecom Federation industry group, in an interview. "Telecom infrastructure, like the railways, covers kilometers across the whole territory -- you can't put surveillance on every part of it."

Adobe Exec: Early Termination Fees Are 'Like Heroin'

Longtime Slashdot reader sandbagger shares a report from The Verge: Early termination fees are "a bit like heroin for Adobe," according to an Adobe executive quoted in the FTC's newly unredacted complaint against the company for allegedly hiding fees and making it too hard to cancel Creative Cloud. "There is absolutely no way to kill off ETF or talk about it more obviously" in the order flow without "taking a big business hit," this executive said. That's the big reveal in the unredacted complaint, which also contains previously unseen allegations that Adobe was internally aware of studies showing its order and cancellation flows were too complicated and customers were unhappy with surprise early termination fees. In response to the quote, Adobe's general counsel and chief trust officer, Dana Rao, said that he was "disappointed in the way they're continuing to take comments out of context from non-executive employees from years ago to make their case." Rao added that the person quoted was not on the leadership team that reports to CEO Shantanu Narayen and that whether to charge early termination fees would "not be their decision." The early termination fees in the FTC case represent "less than half a percent of our annual revenue," Rao told The Verge. "It doesn't drive our business, it doesn't drive our business decisions."

Boeing Starliner Astronauts Have Been In Space Six Weeks Longer Than Originally Planned

Longtime Slashdot reader Randseed writes: Boeing Starliner is apparently still stuck at the ISS, six weeks longer than planned due to engine troubles. The root cause seems to be overheating. NASA is still hopeful that they can bring the two astronauts back on the Starliner, but if not apparently there is a SpaceX Dragon craft docked at the station that can get them home. This is another in a long list of high profile failures by Boeing. This comes after a series of failures in their popular commercial aircraft including undocumented flight system modifications causing crashes of the 737 MAX, doors blowing out in mid-flight, and parts falling off the aircraft. The latter decimated a Toyota in a populated area."I think we're starting to close in on those final pieces of flight rationale to make sure that we can come home safely, and that's our primary focus right now," said Steve Stich, manager of NASA's commercial crew program. "Our prime option is to complete the mission," Stich said. "There are a lot of good reasons to complete this mission and bring Butch and Suni home on Starliner. Starliner was designed, as a spacecraft, to have the crew in the cockpit."

The feat demonstrates that the space agency could provide live coverage of a Moon landing during the Artemis missions and bodes well for the development of optical communications that could connect humans to Mars and beyond. NASA normally uses radio waves to send data and talk between the surface to space but says that laser communications using infrared light can transmit data 10 to 100 times faster than radios.

'Copyright Traps' Could Tell Writers If an AI Has Scraped Their Work

Par : BeauHD
27 juillet 2024 à 03:30
An anonymous reader quotes a report from MIT Technology Review: Since the beginning of the generative AI boom, content creators have argued that their work has been scraped into AI models without their consent. But until now, it has been difficult to know whether specific text has actually been used in a training data set. Now they have a new way to prove it: "copyright traps" developed by a team at Imperial College London, pieces of hidden text that allow writers and publishers to subtly mark their work in order to later detect whether it has been used in AI models or not. The idea is similar to traps that have been used by copyright holders throughout history -- strategies like including fake locations on a map or fake words in a dictionary. [...] The code to generate and detect traps is currently available on GitHub, but the team also intends to build a tool that allows people to generate and insert copyright traps themselves. "There is a complete lack of transparency in terms of which content is used to train models, and we think this is preventing finding the right balance [between AI companies and content creators]," says Yves-Alexandre de Montjoye, an associate professor of applied mathematics and computer science at Imperial College London, who led the research. The traps aren't foolproof and can be removed, but De Montjoye says that increasing the number of traps makes it significantly more challenging and resource-intensive to remove. "Whether they can remove all of them or not is an open question, and that's likely to be a bit of a cat-and-mouse game," he says.

Crooks Bypassed Google's Email Verification To Create Workspace Accounts, Access 3rd-Party Services

Par : BeauHD
27 juillet 2024 à 01:25
Brian Krebs writes via KrebsOnSecurity: Google says it recently fixed an authentication weakness that allowed crooks to circumvent the email verification required to create a Google Workspace account, and leverage that to impersonate a domain holder at third-party services that allow logins through Google's "Sign in with Google" feature. [...] Google Workspace offers a free trial that people can use to access services like Google Docs, but other services such as Gmail are only available to Workspace users who can validate control over the domain name associated with their email address. The weakness Google fixed allowed attackers to bypass this validation process. Google emphasized that none of the affected domains had previously been associated with Workspace accounts or services. "The tactic here was to create a specifically-constructed request by a bad actor to circumvent email verification during the signup process," [said Anu Yamunan, director of abuse and safety protections at Google Workspace]. "The vector here is they would use one email address to try to sign in, and a completely different email address to verify a token. Once they were email verified, in some cases we have seen them access third party services using Google single sign-on." Yamunan said none of the potentially malicious workspace accounts were used to abuse Google services, but rather the attackers sought to impersonate the domain holder to other services online.

Courts Close the Loophole Letting the Feds Search Your Phone At the Border

Par : BeauHD
27 juillet 2024 à 00:45
On Wednesday, Judge Nina Morrison ruled that cellphone searches at the border are "nonroutine" and require probable cause and a warrant, likening them to more invasive searches due to their heavy privacy impact. As reported by Reason, this decision closes the loophole in the Fourth Amendment's protection against unreasonable searches and seizures, which Customs and Border Protection (CBP) agents have exploited. Courts have previously ruled that the government has the right to conduct routine warrantless searches for contraband at the border. From the report: Although the interests of stopping contraband are "undoubtedly served when the government searches the luggage or pockets of a person crossing the border carrying objects that can only be introduced to this country by being physically moved across its borders, the extent to which those interests are served when the government searches data stored on a person's cell phone is far less clear," the judge declared. Morrison noted that "reviewing the information in a person's cell phone is the best approximation government officials have for mindreading," so searching through cellphone data has an even heavier privacy impact than rummaging through physical possessions. Therefore, the court ruled, a cellphone search at the border requires both probable cause and a warrant. Morrison did not distinguish between scanning a phone's contents with special software and manually flipping through it. And in a victory for journalists, the judge specifically acknowledged the First Amendment implications of cellphone searches too. She cited reporting by The Intercept and VICE about CPB searching journalists' cellphones "based on these journalists' ongoing coverage of politically sensitive issues" and warned that those phone searches could put confidential sources at risk. Wednesday's ruling adds to a stream of cases restricting the feds' ability to search travelers' electronics. The 4th and 9th Circuits, which cover the mid-Atlantic and Western states, have ruled that border police need at least "reasonable suspicion" of a crime to search cellphones. Last year, a judge in the Southern District of New York also ruled (PDF) that the government "may not copy and search an American citizen's cell phone at the border without a warrant absent exigent circumstances."

Nvidia's Open-Source Linux Kernel Driver Performing At Parity To Proprietary Driver

Par : BeauHD
27 juillet 2024 à 00:02
Nvidia's new R555 Linux driver series has significantly improved their open-source GPU kernel driver modules, achieving near parity with their proprietary drivers. Phoronix's Michael Larabel reports: The NVIDIA open-source kernel driver modules shipped by their driver installer and also available via their GitHub repository are in great shape. With the R555 series the support and performance is basically at parity of their open-source kernel modules compared to their proprietary kernel drivers. [...] Across a range of different GPU-accelerated creator workloads, the performance of the open-source NVIDIA kernel modules matched that of the proprietary driver. No loss in performance going the open-source kernel driver route. Across various professional graphics workloads, both the NVIDIA RTX A2000 and A4000 graphics cards were also achieving the same performance whether on the open-source MIT/GPLv2 driver or using NVIDIA's classic proprietary driver. Across all of the tests I carried out using the NVIDIA 555 stable series Linux driver, the open-source NVIDIA kernel modules were able to achieve the same performance as the classic proprietary driver. Also important is that there was no increased power use or other difference in power management when switching over to the open-source NVIDIA kernel modules. It's great seeing how far the NVIDIA open-source kernel modules have evolved and that with the upcoming NVIDIA 560 Linux driver series they will be defaulting to them on supported GPUs. And moving forward with Blackwell and beyond, NVIDIA is just enabling the GPU support along their open-source kernel drivers with leaving the proprietary kernel drivers to older hardware. Tests I have done using NVIDIA GeForce RTX 40 graphics cards with Linux gaming workloads between the MIT/GPL and proprietary kernel drivers have yielded similar (boring but good) results: the same performance being achieved with no loss going the open-source route. You can view Phoronix's performance results in charts here, here, and here.

How a Cheap Barcode Scanner Helped Fix CrowdStrike'd Windows PCs In a Flash

Par : BeauHD
26 juillet 2024 à 23:20
An anonymous reader quotes a report from The Register: Not long after Windows PCs and servers at the Australian limb of audit and tax advisory Grant Thornton started BSODing last Friday, senior systems engineer Rob Woltz remembered a small but important fact: When PCs boot, they consider barcode scanners no differently to keyboards. That knowledge nugget became important as the firm tried to figure out how to respond to the mess CrowdStrike created, which at Grant Thornton Australia threw hundreds of PCs and no fewer than 100 servers into the doomloop that CrowdStrike's shoddy testing software made possible. [...] The firm had the BitLocker keys for all its PCs, so Woltz and colleagues wrote a script that turned them into barcodes that were displayed on a locked-down management server's desktop. The script would be given a hostname and generate the necessary barcode and LAPS password to restore the machine. Woltz went to an office supplies store and acquired an off-the-shelf barcode scanner for AU$55 ($36). At the point when rebooting PCs asked for a BitLocker key, pointing the scanner at the barcode on the server's screen made the machines treat the input exactly as if the key was being typed. That's a lot easier than typing it out every time, and the server's desktop could be accessed via a laptop for convenience. Woltz, Watson, and the team scaled the solution -- which meant buying more scanners at more office supplies stores around Australia. On Monday, remote staff were told to come to the office with their PCs and visit IT to connect to a barcode scanner. All PCs in the firm's Australian fleet were fixed by lunchtime -- taking only three to five minutes for each machine. Watson told us manually fixing servers needed about 20 minutes per machine.
