  • Amazon's HR Lead Uses AI Tool to Write 100,000 Lines of Code - 25 Years After She Last Coded
    by EditorDavid on 31/08/2026 at 4:34 am

    In an Amazon News blog post, their HR leader describes using AI to write 100,000 lines of code — 25 years after she last coded. "Do you know how empowering it is to realize that after 25 years away from coding, you can actually build again?" First she built a calendar app for her family, but then used Amazon's AI-powered coding tool Kiro to write an app for Amazon's internal "Everyone Can Build" event. We opened the competition to every employee on our team, and within just a few weeks, more than 1,500 people were building. I couldn't believe what they built. One employee built an app that turned a nearly four-hour manual process into a one-second automated check, saving tens of thousands of hours annually. Another made a desktop pet named Momo that keeps your tasks, reminders, and shortcuts a click away. Since then, I've written over 100,000 lines of code with AI. What I've found is that the more you work with these tools, the more natural the process becomes, and the more you realize they're expanding what you're capable of, not replacing it. You don't need perfection to start. You just need to dive in. When I decided to build the submission app for our team competition, I didn't know how to begin, so I asked our internal AI workplace assistant, called Aza. It pointed me to the right tools and helped me take the first step. From there, I opened Kiro and started building. When you give employees the ability and tools to solve problems themselves, they will surprise you with what they create... At Amazon, every employee has access to AI tools. Whether someone needs a quick answer, wants to move faster in their day-to-day, or is ready to try building something new, the resources are there. The more people use these tools, the more capable they become with them, and that experience carries forward in their careers... We also want to make it easy for people to build credentials that are recognized across industries. That's why AI training is free for every Amazon employee. Amazon covers the full cost of one AWS AI certification exam per year, with options ranging from foundational AI concepts to professional-level generative AI. Employees can choose the path that fits where they are in their learning journey. Long-time Slashdot reader theodp notes that 7 months ago Galetti also took to Amazon News to announce the elimination of 16,000 corporate jobs, a move which CNBC noted coincided "with a push to invest heavily in artificial intelligence." The job reductions come just a few months after October's layoffs, when 14,000 employees were let go across Amazon's corporate workforce. At the time, the company indicated the cuts would continue in 2026 as it found "additional places we can remove layers." Read more of this story at Slashdot.

  • Multikernel Linux Tree Released: Runs Multiple Kernels On Bare Metal Without a Hypervisor
    by EditorDavid on 31/08/2026 at 2:26 am

    "Multikernel Technologies has put out mklinux v7.0-mk2, the first public release of the multikernel Linux tree it's been building since last year," reports the blog It's FOSS: The basic premise of the project is that one physical server can run several independent Linux kernels side by side, each with its own dedicated CPUs and memory. So, the same box could run a database on one kernel and a GPU training job on another without either kernel touching the other's resources... One kernel runs as the host, controlling the machine's CPUs, memory, and PCI devices. When it spins up a new kernel instance, that instance gets its own dedicated slice of hardware and boots straight onto it using Linux's kexec mechanism, running natively rather than under a hypervisor. The host tracks all of this through device tree overlays under /sys/fs/multikernel/, and it can shift hardware between running instances while everything stays up. That's a different setup from both VMs and containers. A VM still puts a hypervisor and a host kernel between the app and the hardware. A container skips the hypervisor, but every tenant on the machine shares one kernel... This release only supports x86_64 hardware, though Multikernel Technologies says the architecture-specific code is already modular enough for other ports to follow later. The article notes they're selling multiple products based on the kernel tree, including one for running AI agents in their own kernel with direct GPU access and one that promises to patch a running kernel without taking the system down.

  • Gamescom Crime Spree? Three Exhibitors Report Their Laptops Were Stolen
    by EditorDavid on 31/08/2026 at 12:38 am

    From the gaming news site Aftermath" Game developer and consultant Ryan Laley traveled to Cologne, Germany from Essex, England to showcase his upcoming horror social deduction game Mimic at the annual Gamescom event. He paid "thousands of pounds" to get a booth at the show, where other game developers and press could try the game ahead of its October release. But Laley's Gamescom was cut short when he realized Friday morning that his brand new Alienware laptop, purchased for the event, was missing. The laptop was stored in a cupboard in the booth, and Laley started asking nearby vendors to see if someone had moved it. That's when he realized it was stolen — and that he wasn't alone. Laley's booth in Gamescom's business area, specifically in the International Game Developers Association Lounge, had been hit in what appears to be a string of thefts at the convention center. The business area of the convention is not open to the public, only press and others with specific tickets. Laley said Gamescom advertised this area as having 24/7 security and limited access after hours... Publisher and merchandiser iam8bit, in a nearby booth showcasing Escape Academy 2: Back 2 School and Petal Runner, had two laptops with game builds stolen Thursday night from its booth, a representative confirmed to Aftermath. "Meanwhile, Tessera Studios had two laptops and a Steam Deck taken from its cabinet," reports Tom's Hardware: Gamescom organizers responded to the issues, saying that although they have arranged for uniformed guards to provide general security, individual booth security must be booked separately. They've also advised exhibitors to have insurance against theft, and said these warnings are noted in the terms and conditions for participants, as well as in the event's technical guidelines. "All cases have been reported to us and to the police, and investigations are already underway," the organizers' statement read. They also said that security is one of their priorities at the event, but also added, "At an event of this size, however, there will always be individuals attempting to take advantage of the situation."

  • AI's 'Creepy' Crawlers Criticized by Linux Foundation's IT Infrastructure Director
    by EditorDavid on 30/08/2026 at 10:38 pm

    The Linux Foundation's director of IT infrastructure says they now spend more CPU cycles "rendering commits for scrapers than we spend on all other kinds of legitimate access." At any one time, across 5 geo-distributed nodes, there are 14 CPU cores doing nothing but rendering git commits as html.... [W]hen a source is guaranteed to be LLM-free, like the entire history of kernel commits, it's worth its weight in gold as a source of training data... At the time of writing, linux.git is about 1.48 million commits. Oh, and we have about 922 forks of it on git.kernel.org — but don't worry, it's actually extremely efficient on the backend, since it's mostly the same objects in every fork. Unless, of course, you're a scraper, in which case you have, oh, several BILLION valid URLs you can scrape, only to get 922 duplicates of the same 1.48 million commits — which is exactly what the scrapers are doing. But wait, it's not just commits itself. You can also ask for patches, plain renders, diffs between arbitrary commits — cgit is happy to let you, which was perfect for the times when the Internet was for humans or crawlers who obeyed robots.txt, and is AWFUL right about now, because we can generate 1.2 METRIC BAJILLION valid URLs just for a single fork of linux.git. Initially, this was the solution — look through the logs, find out which IPs are obvious scraper bots, and fail2ban them. At first, this was easy, because the bots helpfully told you who they were via their user-agent. Then, they wised up and started pretending that they were random vanilla browsers. So, we started banning them by IP — after all, it's easy to figure out that an IP that is trying to grab every possible commit in a 8-year-old abandoned fork of linux is not really some lone Chrome on Windows user who is just furiously clicking every link that comes across their screen. The bots then started fanning out to entire subnets, but this was still meh, because obviously an IP coming from Google Compute is just pretending to be a Firefox user... And... that's when things turned really, really ugly. Suddenly, the crawlers were coming from millions of random residential or mobile IPs, all pretending to be random modern browsers. An IP like that would make 4-5 requests and then never show up in the logs again... They descended like swarms of locust, hit hard and fast until the system fell over and then moved on to the next target until you recovered. Then, they returned. Rinse. Repeat. They still do that — welcome to the wonderful world of "proxy SDK monetization." It's big business, and your TV is probably doing it... Today, git.kernel.org receives about 6M daily requests demanding to see random commits. Of these, 66% are still immediately batted away with the Anubis challenge, but 33% are now solving the math and getting through to the main site — because apparently what we have to offer is worth spending a ton of cycles to calculate the Anubis challenge... With a bunch of generous assumptions, legitimate requests are only about 2% of git.kernel.org traffic — everything else are scrapers... [W]e're turning off features to reduce the number of crawlable URLs and to gate off actions that are expensive for us to run. Expect to lose some functionality, at least when accessing our resources anonymously. Trust me, we hate it just as much as you, but at this point it's a necessity... [W]e promise to still offer all of our data for download to anyone who asks. You just may have to jump through more hoops to get it. Sorry. Read more of this story at Slashdot.

  • Chess.com Launches New Poker Site, Plans More Classic Game Sites with Player Ratings - Thanks to AI Protyping
    by EditorDavid on 30/08/2026 at 8:20 pm

    In May Chess.com "quietly launched" a free educational poker site named Gambit, reports The Verge, where players can learn the game and improve an Elo-like rating without risking real money. And next Chess.com will expand into more classic games, including go, backgammon, and mahjong: Like Gambit, Chess.com is developing Elo-style rating systems for these games, as well. [Chess.com's chief growth officer, Albert Cheng] didn't say when the new sites will launch but that "development is moving quite rapidly" on them, using the same playbook he used for Gambit... He and one other employee took Gambit from prototype to launch within a year, partly with help from AI, mainly for coding tasks. "I think the biggest advantage that it's provided is essentially being able to read our existing codebase and our design system and apply consistent patterns to how we develop Chess.com over to a different platform and do so quickly," Cheng said.... "Just because code is easier to write doesn't mean that you just let it run on its own, but it certainly is a superpower in getting things off the ground." Cheng also said the version of Gambit that's live at the time of writing has "zero or close to zero" AI-created assets, which were used in early prototypes. According to Cheng, without help from AI, getting another site up and running would have required a bigger team or "would have been a lot more disruptive to the status quo of building and growing Chess." Now that a "small, scrappy" team can get a new platform off the ground much faster, it's opened the door for Chess.com to dip into more games, starting with poker. The poker site already has 75,000 members, according to a blog post Friday — and they've already played nearly 20 million hands and completed 100,000 lessons. The site is now holding a daily poker tournament, and on Monday will broadcast the event with live commentary on their Twitch and YouTube channels. Read more of this story at Slashdot.

  • Google Maps Renamed Lake Ontario to 'Lake America' - But Only for U.S. Users
    by EditorDavid on 30/08/2026 at 6:53 pm

    It's already happened — at least on Google Maps. Google's online maps reflect name changes in official government sources, Google posted Saturday. So when the U.S. Geographic Names Information System formally changed the name for "Lake Ontario" to "Lake America," Google also renamed it "Lake America" — for visitors from the U.S. "Those in Canada will continue to see 'Lake Ontario'," Google said. And people from every other country in the world... "will see both names." Though here's how it will be written... Lake Ontario (Lake America) "These updates follow our long-standing policy for bodies of water with names that vary from country to country, and are starting to roll out now." Meanwhile, NPR reports that Ontario's Premier posted a billboard reading "Lake Ontario — Now and Always" on Canada's side of the lake (repeating the message in French). And The Daily Beast reports Google move has also drawn some criticism online: "Hey you gave one of the Great Lakes the wrong name; pretty embarrassing mistake so you might want to fix that," one user wrote on X... MapQuest has said it will not be changing the name, and instead launched a new tool that allows users to rename it themselves to whatever they want. Read more of this story at Slashdot.
