  • Waymo CEO Explains Why Camera-Only Self-Driving Falls Short
    by BeauHD on 05/08/2026 at 11:00 pm

    Longtime Slashdot reader AmiMoJo shares a report from Electrek: Waymo co-CEO Dmitri Dolgov laid out the clearest technical case yet for why cameras alone can't take a self-driving system to full autonomy, arguing that "weak sensing" hits a safety ceiling long before it reaches superhuman performance. [...] Dolgov made the comments in a talk at Y Combinator's Startup School, walking through the lessons Waymo has learned building its driver over close to two decades. He put the sensor question on the table plainly: "there's been a long-standing debate about what kind of sensors do you actually need for autonomous driving." His answer draws the line that camera-only advocates tend to skip right past. "Humans of course can drive with just eyes, so there's that proof of existence," he said. "If the goal were to just approximately match human performance or to build an assist product, that's a very reasonable way to go." Then the catch. If you're targeting full autonomy and strongly superhuman performance, he said, "you find that weak sensing just leads to a safety curve that flattens out way too early." Dolgov said that cameras, lidar, and radar are complementary rather than redundant: "These different sensing modalities, they're not backups to each other," and combining them produces a view "vastly superior to what you get with any one sensor." He said multiple sensor types also protect against physical failures, such as a leaf or branch blocking a camera, while helping Waymo climb the "exponential ladder of nines" required for fully driverless safety. Dolgov warned that camera-only systems may improve quickly before plateauing "way before the performance that is required by your product." He also pushed back on the cost argument against lidar, calling it "a number that has a fairly short shelf life" as hardware costs continue to fall. Read more of this story at Slashdot.

  • Anthropic's AI Used Fake Identities, Malware In Rogue Attack On GitHub Project
    by BeauHD on 05/08/2026 at 10:00 pm

    An anonymous reader quotes a report from Ars Technica: Routine cybersecurity testing of frontier AI models sparked a series of unexpected security incidents -- the most serious case arising when Anthropic's Mythos 5 model attempted to insert malicious code into an open source software application and created fake identities to deceive the human developers maintaining the project. The security incidents occurred during a cyber evaluation of seven leading AI models' capabilities by the AI Security Institute (AISI), a research organization within the UK government, in late July. The researchers discovered (PDF) 19 instances in which "AI agents took unsanctioned action on the live Internet, including cases that targeted real people and organizations," according to an AISI blog post published on August 4. Almost all the "autonomous, unsanctioned" actions came from Anthropic's Mythos 5 model, with two such actions coming from OpenAI's GPT-5.6 Sol. [...] The most serious case involved Mythos making multiple attempts to execute a supply chain attack on the open source project repository hosted on the developer platform GitHub, including using social engineering techniques to try to convince the repository's human maintainers to merge malicious code into the repository. After first opening a pull request to merge the malicious code into the repository, Mythos created fake online "sock puppet" personas that claimed to have independently reviewed and verified the code as not containing malware. The AI agent also sent five emails to two human maintainers of the repository, including some emails containing malware and others attempting to persuade a maintainer to accept the pull request. Mythos even opened a GitHub Issue on a second repository -- also owned by a maintainer of the first repository -- that contained a prompt injection with malicious instructions targeting "issue-triage AI coding agents." This line of attack came from Mythos reasoning that the repository maintainer could be an AI coding agent such as Claude Code. Read more of this story at Slashdot.

  • Meta Debuts First AI Coding Agent To Take On Anthropic and OpenAI
    by BeauHD on 05/08/2026 at 9:00 pm

    Meta has launched Muse Code, its first AI coding agent that's positioned as a lower-cost rival to Anthropic's Claude and OpenAI's Codex. It offers pay-as-you-go pricing and an optional zero-data-retention feature for enterprise users. CNBC reports: Muse Code is the latest major release from AI chief Alexandr Wang, who leads Meta Superintelligence Labs and oversees foundation model development. Wang joined in June of last year as the centerpiece of CEO Mark Zuckerberg's effort to revamp his company's flailing artificial intelligence strategy. "You can install it with one command and then use it to take on complete software engineering tasks across a wide variety of use cases, planning changes, writing code, validating the results," Wang said in an interview on Wednesday. [...] The new tool, like Anthropic's Claude and OpenAI's Codex assistants, makes it easier for people to build apps within a single user interface while managing fleets of AI-powered digital agents that can help underpin the software development process. Muse Code, available in a preview version, works alongside the company's latest AI model, Muse Spark 1.2. Wang declined to share user statistics related to the company's Muse Spark AI models, but said "adoption has been exciting and strong." The latest Muse Spark model was developed and trained alongside Muse Code, which Wang said improves the overall coding performance. Read more of this story at Slashdot.

  • Apple's 'Private Relay' Is Exposing Users' Real IP Addresses
    by BeauHD on 05/08/2026 at 8:00 pm

    Security researchers found that Apple's iCloud Private Relay can expose users' real IP addresses because some passkey-related requests bypass Safari and its proxy protections at the operating-system level. "In short: any website that supports, or pretends to support, passkeys can see the user's real IP address despite having iCloud Private Relay on," security researcher Tommy Mysk, who discovered the issue along with Talal Haj Bakry, told 404 Media. The flaws also affect OnionBrowser, an iOS app for browsing the web through the Tor anonymity network. It does not, however, impact the official Tor Browser itself. From the report: The researchers developed a site that lets Private Relay users check if the issues impact them. In 404 Media's tests, the site did return the real IP address of a user that was supposed to be protected by Private Relay. [...] In a quirk of how passkeys work -- a broadly secure alternative to usernames and passwords which use the WebAuthn standard -- a user's device makes a web request outside of the browser itself. Meaning, that request essentially bypasses Private Relay and exposes a user's real IP address, even though to them it may look like they are simply interacting with a website as normal. "Because the fetch is issued by the operating system's credential service rather than by Safari, it never enters Private Relay's proxied path. The destination server sees the device's real IP address either way," the researchers write in their research. [...] "We have already informed them. They said the issue was âdire,' but they let us disclose the issue. They didn't provide any time when they will address this," Mysk said. Read more of this story at Slashdot.

  • Lawmaker Who Wants Data Center Pause Wins Kansas Democratic Primary
    by BeauHD on 05/08/2026 at 7:00 pm

    Kansas Democrats nominated State Senator Cindy Holscher for governor after she defeated party-backed rival Ethan Corson. "The race became a test of what sort of candidate Democratic voters prefer in what is expected to be a challenging general election race: a more moderate candidate like Mr. Corson with endorsements from party leaders or an outspoken populist like Ms. Holscher, who spoke out against data centers and the political establishment," reports The New York Times. From the repot: Even in a national political environment that could favor Democrats, Republicans see the Kansas governorship as among their best opportunities for flipping a seat. President Trump carried Kansas by 16 percentage points in 2024, and Republicans hold supermajorities in the State Legislature. Voters in the Republican primary for governor nominated Ty Masterson, the president of the Kansas Senate and the recipient of Mr. Trump's endorsement, according to The A.P. Ms. Holscher, who is from suburban Kansas City, sought out a lane to Mr. Corson's political left and made inroads with some of the state's progressive voters. She emphasized her role in unwinding former Gov. Sam Brownback's tax policies and called for a moratorium on data centers. She also spoke against a final deal to lure the Kansas City Chiefs across the state line from Missouri. Ms. Holscher presented an implicit critique of Ms. Kelly's stewardship of Kansas, referring to Mr. Corson as part of a political establishment that was too cozy with corporations and out of touch with the party's voters. "I'm the only Democrat in this race to call for a moratorium on data centers because we have to get these guardrails in place," said Holscher in an interview. "We are having our people and our resources exploited." Read more of this story at Slashdot.

  • Google Overhauls AI Leadership As DeepMind CEO Steps Aside
    by BeauHD on 05/08/2026 at 6:00 pm

    Google is reshuffling its AI leadership as Demis Hassabis steps away from day-to-day management of DeepMind to become chairman and Alphabet's chief scientist, while CTO Koray Kavukcuoglu takes operational control. Meanwhile, longtime chief scientist Jeff Dean and several prominent researchers are leaving to launch their own company. Axios reports: Hassabis will add the title of chief scientist for Google parent company Alphabet and also continue to lead Isomorphic Labs, the company's AI drug discovery spinoff. Koray Kavukcuoglu, the current chief technology officer of Google DeepMind will serve as senior VP of the unit, reporting to CEO Sundar Pichai. Dean, a 27-year Google veteran is starting Discovery Loop, an independent publicity benefit corporation in which Google will be an investor and cloud provider. Joining him in that effort are Google senior fellow Sanjay Ghemawat as well as Oriol Vinyals, a DeepMind VP and Quoc Le, a Google Brain co-founder. [...] In an interview with The New York Times, Dean indicated that leaving Google, a public company, gives him more leeway to focus on scientific discoveries associated with AI as well. "We might make decisions that are not necessarily in the company's purist financial interests," he told NYT. "I've been working towards AGI my whole life and now, like many of you, I feel it is close at hand," Hassabis wrote. "It's critical that we collectively get the next steps right to ensure this all goes well for humanity and we usher in an incredible new age of discovery and wonder." "With this backdrop, I've decided that now is the right time for me to hand over my day-to-day operational responsibilities at GDM, so that I have the time and space to focus on the big picture and help influence what is to come to the best of my ability" Read more of this story at Slashdot.
