  • OpenAI Co-Founder Andrej Karpathy Joins Anthropic
    by BeauHD on 19/05/2026 at 8:00 pm

    OpenAI co-founder Andrej Karpathy has joined rival AI lab Anthropic. "The hire is a major coup for Anthropic in the high-stakes competition for elite AI talent -- and another sign the company is emerging as a magnet for some of the industry's most respected technical minds," reports Axios. From the report: Karpathy will start this week on Anthropic's pre-training team, which is responsible for the massive training runs that give Claude its core knowledge and capabilities, according to Anthropic. Karpathy will help launch a new team focused on using Claude itself to accelerate pretraining research -- an increasingly important frontier as AI companies race to automate parts of AI development. "I think the next few years at the frontier of LLMs will be especially formative. I am very excited to join the team here and get back to R&D," Karpathy said in a post on X. Karpathy is a rare AI figure with credibility across research, industry and education. He was a founding member of OpenAI before serving as Tesla's director of AI, where he led the computer vision team behind Autopilot. Karpathy coined the term "vibe coding" and recently described himself as being in a "state of AI psychosis" since December -- embracing "tokenmaxxing" and aggressively stress-testing frontier models.

  • StanChart To Cut Over 7,000 Jobs, Boost AI To Replace 'Lower-Value Human Capital'
    by BeauHD on 19/05/2026 at 7:00 pm

    The London-headquartered lender Standard Chartered announced plans to cut more than 7,000 jobs by 2030, with CEO Bill Winters saying the bank will replace some "lower-value human capital" through automation and AI while offering retraining to affected workers. "It's not cost-cutting. It's replacing in some cases lower-value human capital with the financial capital and the investment capital we're putting in," CEO Bill Winters told reporters. "So, the people that want to reskill, that want to carry on, we're giving every opportunity to reposition," Winters said. Reuters reports: The cuts, alongside higher shareholder return targets announced in a strategy update, come as StanChart is at the tail-end of a decade-long effort to transform itself from a potential takeover target to a steadily profitable lender. Its London-listed shares, which have risen 65% in the last 12 months, fell 0.5% in early trading, as analysts said the new targets were at the conservative end of their expectations. "In a world full of uncertainty, performance may prove more challenging further out," said Ed Firth, analyst at Keefe, Bruyette & Woods, citing how the bank has benefited in recent years from high interest rates and huge wealth flows. StanChart's move to streamline operations and rein in costs comes as more global firms slash jobs by deploying AI to improve efficiency. Japanese lender Mizuho in March unveiled up to 5,000 job cuts over a decade. And banks globally are scrambling to integrate frontier AI models and fend off rising cyber threats. The most affected roles will be in the bank's back-office centres, including those in Chennai, Bengaluru, Kuala Lumpur and Warsaw, according to Winters. "Of course we're using AI along the way and AI will be a huge facilitator and enabler of that," he added, referring to its ongoing revamp to automate more of its core banking system. StanChart said it would deliver over 15% return on tangible equity in 2028, more than three percentage points higher than in 2025, and building to about 18% in 2030. Meta also announced plans to reassign 7,000 employees into AI-related initiatives, just ahead of layoffs expected to affect roughly 8,000 workers. Read more of this story at Slashdot.

  • CISA Admin Leaked AWS GovCloud Keys On Github
    by BeauHD on 19/05/2026 at 6:00 pm

    An anonymous reader quotes a report from KrebsOnSecurity: Until this past weekend, a contractor for the Cybersecurity & Infrastructure Security Agency (CISA) maintained a public GitHub repository that exposed credentials to several highly privileged AWS GovCloud accounts and a large number of internal CISA systems. Security experts said the public archive included files detailing how CISA builds, tests and deploys software internally, and that it represents one of the most egregious government data leaks in recent history. On May 15, KrebsOnSecurity heard from Guillaume Valadon, a researcher with the security firm GitGuardian. Valadon's company constantly scans public code repositories at GitHub and elsewhere for exposed secrets, automatically alerting the offending accounts of any apparent sensitive data exposures. Valadon said he reached out because the owner in this case wasn't responding and the information exposed was highly sensitive. The GitHub repository that Valadon flagged was named "Private-CISA," and it harbored a vast number of internal CISA/DHS credentials and files, including cloud keys, tokens, plaintext passwords, logs and other sensitive CISA assets. Valadon said the exposed CISA credentials represent a textbook example of poor security hygiene, noting that the commit logs in the offending GitHub account show that the CISA administrator disabled the default setting in GitHub that blocks users from publishing SSH keys or other secrets in public code repositories. "Passwords stored in plain text in a csv, backups in git, explicit commands to disable GitHub secrets detection feature," Valadon wrote in an email. "I honestly believed that it was all fake before analyzing the content deeper. This is indeed the worst leak that I've witnessed in my career. It is obviously an individual's mistake, but I believe that it might reveal internal practices." "Currently, there is no indication that any sensitive data was compromised as a result of this incident," a CISA spokesperson wrote. "While we hold our team members to the highest standards of integrity and operational awareness, we are working to ensure additional safeguards are implemented to prevent future occurrences." The GitHub account in question was taken offline shortly after CISA was notified about the exposure. However, according to Caturegli, the exposed AWS keys remained valid for another 48 hours. "What I suspect happened is [the CISA contractor] was using this GitHub to synchronize files between a work laptop and a home computer, because he has regularly committed to this repo since November 2025," Caturegli said. "This would be an embarrassing leak for any company, but it's even more so in this case because it's CISA." Read more of this story at Slashdot.

  • Microsoft Launches Surface Pro 12, Surface Laptop 8 With Intel Chips
    by BeauHD on 19/05/2026 at 5:00 pm

    Microsoft is launching three new Intel-powered Surface devices for businesses: the Surface Pro 12, Surface Laptop 8, and a smaller 13-inch Surface Laptop model. These new machines come equipped with newer Intel chips, a few business-focused upgrades, and notably higher starting prices. "The high pricing of these three new Surface devices is a sign of things to come for whatever consumer models Microsoft is planning this year," notes The Verge. From the report: This time around Microsoft is refreshing its Surface Pro and Surface Laptop models with Intel's latest Core Ultra Series 3 processors first, ahead of similar models with Qualcomm's new Snapdragon X2 processors later this year. The new Surface Pro 12, or as Microsoft calls it the Surface Pro for Business 13-inch (12th Edition), will be available for businesses today, starting at an eye-watering $1,949.99. The base model will include an Intel Core Ultra 5 processor, 16GB of RAM, 256GB of storage, and the regular 13-inch PixelSense LCD display. Businesses will have to pay extra for models with Intel's Core Ultra 7 processor, up to 64GB of RAM, and up to 1TB of storage. The top spec Surface Pro 12 with a Core Ultra 7, 64GB of RAM, and 1TB of storage will be priced at $4,399.99, and there are also OLED screen options and models with 5G connectivity. The Surface Pro 12 5G starts at $2,249.99, with a Core Ultra 5, 16GB of RAM, and 256GB of storage. [...] Microsoft is also launching two new versions of the Surface Laptop for businesses today. The Surface Laptop 8, or Surface Laptop for Business 13.8 or 15-inch (8th Edition) as Microsoft calls it, will also be available with a range of Intel's Core Ultra Series 3 chips. It launches alongside a smaller 13-inch model, which is confusingly labeled the Surface Laptop for Business 13-inch (1st Edition). The 13.8-inch model starts at $1,949.99, and includes Intel's Core Ultra 5 processor, 16GB of RAM, and 256GB of storage. While Surface devices for businesses have typically had higher pricing than consumer models, the $1,949.99 starting price for a Surface Laptop 8 is almost double the original price of the Surface Laptop 7. RAMageddon really has come for Microsoft's Surface Pro and Surface Laptop devices, after recent price increases meant the existing consumer models are now $500 more expensive than their original starting price. The max configuration for the 13.8-inch Surface Pro 8 will include a Core Ultra 7, 64GB of RAM, and 1TB of storage for $4,299.99. A similar version of the 15-inch model (with an x7 processor) will be priced at $4,499.99. Read more of this story at Slashdot.

  • Microsoft Surprises With Its First Server Linux Distribution: Azure Linux 4.0
    by BeauHD on 19/05/2026 at 4:00 pm

    Microsoft is turning Azure Linux into a general-purpose, Fedora-based cloud distribution available to all Azure customers, while also productizing Flatcar as Azure Container Linux for immutable container hosts. "When Microsoft joined the Linux Foundation, there was this big conspiracy theory that somehow the Linux Foundation was undermining open source in partnership with Microsoft, and now you announce that you're shipping a Linux distribution," Jim Zemlin, the Linux Foundation's CEO, said in response to Microsoft's surprise announcement. "That's amazing." ZDNet reports: Until now, [Lachlan Everson, Microsoft's Principal Program Manager on Azure's open-source team] noted, "we had Azure Linux only available to third-party customers through AKS specifically, and that was Azure Linux 3.0." Going forward, this will be ACL. Everson emphasized that Azure Linux 4.0 is the culmination of years of internal usage and the evolution of the earlier Mariner distribution. "So we've been running Azure Linux for many years internally, and we got through to 3.0, and we only allowed it on as a container host on AKS. What we've done is make it a general-purpose, so this is all the learnings that we've had in the heritage of Mariner." Under the hood, Azure Linux 4.0 is based on Fedora Linux and is delivered as an open distribution on GitHub. This code is available now. Yes, Red Hat knows that Microsoft has done this. Everson continued, "So, we made a decision to use Fedora as an upstream, so it's using RPMs in the Fedora ecosystem. Microsoft curates the packages and the supply chain to fit Azure's cloud platform." Microsoft also created "it to be purpose-built for Azure, which integrates vertically into all of our infrastructure to give you the best Azure Linux experience on Azure." While Azure Linux will ship as a VM image, Microsoft is already preparing a developer-friendly path onto Windows desktops: "And as of today, we have it as a VM image for your VM host on Azure. We're going to announce WSL images as well." While developers will be able to run Azure Linux locally through WSL, Microsoft is not positioning it as a traditional desktop Linux. Asked whether he could run it on his laptop, Everson said: "I will be able to run it on my laptop, or what have you. Yes, on Windows 11." However, when pressed about a desktop experience, Everson was clear that there are "no plans" for a graphical environment. "It's optimized for server-side in the cloud," he said, adding that even on a developer machine, users should expect a lean environment. "Minimal packages, yeah. The idea is that we offer you a consistent experience to do your development on your machine, and that you can take your workloads as you develop them on your machine and run them with VS Code. You can run your applications on that, and know that the platform is the same that you're running on the cloud, so that you have that kind of consistency between environments." Flatcar itself remains the upstream project, but Microsoft is packaging it for Azure customers. Everson described Flatcar as "purpose-built, immutable, secure by default, production-ready operating system, and Azure Container Linux is the productization of that, but we're still investing in the upstream Flatcar ecosystem and pulling that downstream into a productized exterior experience just for container workloads, so it's a container hosting in AKS." To underscore the immutable model, he added that "Everything's baked in, so there is no package manager. We bake the bits into the immutable, and they're in the immutable version. So Azure Container Linux is the immutable version. So you shouldn't be changing any system packages or any application packages. Anything that you need to change is customer workloads run in containers." Read more of this story at Slashdot.

  • Before Mass Layoffs, Meta Reassigns 7,000 Workers To Focus On AI
    by BeauHD on 19/05/2026 at 3:00 pm

    An anonymous reader quotes a report from the New York Times: Meta told employees on Monday that it was reassigning 7,000 workers to focus on new initiatives around artificial intelligence, the latest change in a company transformation spurred by the powerful technology. Employees will be moved to four new organizations focused on building new A.I. tools and apps, Janelle Gale, Meta's head of human resources, said in an internal memo. The organizations will use "A.I. native design structures" and have fewer managers per employee than other parts of the company, she said, adding that company leaders will send details about the new roles on Wednesday. The restructuring "will make us more productive and make the work more rewarding," Ms. Gale wrote. Meta declined to comment further on the changes. The move comes shortly before Meta begins laying off roughly 8,000 employees, or 10 percent of its work force. Ms. Gale also mentioned Wednesday's layoffs in her memo. "We know days like this are extremely hard, and we appreciate you showing up for each other," Ms. Gale said. According to the NYT, employees have been asked to work remotely that day and emails about the layoffs would be sent at 4 a.m. local time. Employees in the United States will receive 16 weeks of severance pay, along with two extra weeks for every year they worked at Meta. Read more of this story at Slashdot.
