  • Snap's First Consumer AI Glasses Are Coming This Fall For $2,195
    by BeauHD on 16/06/2026 at 7:00 pm

    Snap is launching its first consumer augmented-reality glasses this fall for $2,195. "You can preorder a pair of Specs now at specs.com with a $200 refundable deposit, and Snap says they're expected to ship 'this fall' in the US, UK, and France," reports The Verge. From the report: This is a big moment for Snap: The company made a big entry into smart glasses with its original Spectacles in 2016, and the company has been toiling away on nonpublic AR versions of Spectacles over the past few years. CEO Evan Spiegel promised the company would launch consumer AR glasses in 2026 and even turned its smart glasses team into a separate business. The company says that Specs are "fully standalone, with no puck and no tether." (Which is perhaps a jab at Apple's Vision Pro, which is tethered to a separate battery pack.) They'll be offered in two sizes, a 47mm model weighing 132g and a 52mm model weighing 136g, and will have removable inserts that Snap says will support "a wide range of prescriptions." You probably won't mistake Specs, with their wide, bold frames, for any of Meta's smart glasses -- Snap clearly picked a design that it wants to stand out. (They're not my style -- I don't think I can pull off the "snow goggles, but fashionable" look -- though maybe Jony Ive might like them.) They have visible light and infrared cameras, and while the Specs are recording, a little LED bar will glow in the middle of the glasses. Both of the lenses will be able to show you content, and Snap says that its display system is powered by a "proprietary liquid crystal on silicon technology" that offers a 51-degree field of view and can show 16 million colors. The lenses can also go from clear to tinted in 10 seconds, Snap says. The Specs have two Snapdragon processors onboard, and while Snap isn't specifying exactly which ones they are, the company says that one is focused on "computer vision" while the other is focused on running AR Lenses. "Together, they enable fast hand tracking, low latency, and responsive interactions that help digital content feel anchored in the real world," Snap says. You can also expect up to four hours of battery life on a charge, which Snap says accounts for things like "audio and video playback, AI assistance, Bluetooth notifications, and more." The Specs come with a charging case that Snap says will offer four more charges for a total of 20 hours of battery. Read more of this story at Slashdot.

  • SpaceX To Acquire AI Coding Startup Cursor For $60 Billion
    by BeauHD on 16/06/2026 at 6:00 pm

    SpaceX has agreed to acquire Cursor for $60 billion in stock, adding the popular AI coding assistant to Elon Musk's newly public aerospace-and-AI conglomerate. CNBC reports: Cursor built a popular AI coding tool that helps software developers generate, edit and review code, and the company has experienced explosive growth since its founding in 2022. In November, Cursor said it crossed $1 billion in annualized revenue, according to a release at the time. Cursor was also ranked at No. 37 on the annual CNBC Disruptor 50 list in 2026. [...] Musk merged SpaceX with his AI startup, xAI, earlier this year, and the Cursor deal looks set to help revitalize the company's efforts to compete with rivals like Anthropic and OpenAI, which also offer popular coding tools. SpaceX expects the merger to close during the third quarter of this year, according to a filing with the Securities and Exchange Commission. The transaction is subject to "requisite regulatory approvals," the filing said. Read more of this story at Slashdot.

  • The US Government's Anthropic Models Ban Was Never About an AI Jailbreak
    by BeauHD on 16/06/2026 at 5:00 pm

    TechCrunch's Zack Whittaker argues that the U.S. government's abrupt export-control order forcing Anthropic to pull its Fable 5 and Mythos 5 models offline was "never about an AI jailbreak" threat. Instead, it was driven more by "personality differences" between the AI company and Trump administration. Security experts say the reported guardrail bypass did not justify the order and warn that the move sets a troubling precedent: the government can unilaterally disrupt American software products without court approval, potentially undermining trust in U.S. AI providers. From the report: Katie Moussouris, a cybersecurity veteran and researcher who founded Luta Security, said in a blog post that Anthropic recently shared with her a private copy of a paper written by security researchers describing an alleged guardrail bypass in Fable 5. (The Wall Street Journal reports that the paper's authors are security researchers at Amazon.) Moussouris said that Anthropic reached out to ask for her take on the paper. Moussouris' blog post described how the researchers triggered the guardrail bypass, but said that the bypass itself "should never have triggered an export control." The difference is largely between asking an AI model to "review code for security issues" versus asking it to "fix this code." The end result is largely the same, even if the questions are posed slightly differently. "The behavior described in the paper cannot meaningfully be fixed, and any attempt would only weaken the model for defense," said Moussouris, who criticized the export control directive as hasty, heavy-handed, and misguided. Moussouris and dozens of other top security researchers and experts have since called on the Trump administration to revoke the export control order, calling the move to pull advanced cybersecurity capabilities from network defenders in the U.S. as "dangerous." Past administrations have made sweeping decisions on knowledge gaps. For instance, language used by the U.S. government during the 2010s to fix export law covering cybersecurity tools that could also be used for cyberattacks was so broad that inadvertently, it nearly outlawed legitimate security and vulnerability research. However, the Trump administration's directive appears retaliatory. Justin Hendrix, the editor of Tech Policy Press, said the Trump administration's move is "likely to raise alarms in foreign capitals about the reliability of American AI for critical applications." The message is that AI companies in the United States can't be trusted to operate without interference from the U.S. government. The Trump administration hasn't confirmed why it invoked its export control directive. Did the officials misread the report and freak out? Did Amazon CEO Andy Jassy say something to senior government officials that prompted the reaction, out of caution or spite? Was something lost in translation, or was this a way to pressure Anthropic, with whom the administration already has a fractious relationship? It's possible that the White House was unaware of the far-reaching consequences of the letter's demand and officials are scrambling to undo the damage of their own making. To quote Hendrix, "the climate is one of a cloud of suspicion that senior officials are picking favorites based on personal and political factors." The aftermath is that the government has set a dangerous precedent about how much control it intends to wield over the release of American-made software. This time the government took issue with Anthropic; tomorrow it could be with anyone else. Read more of this story at Slashdot.

  • Russian Spam and Profanities Are Now Plaguing the Arch Linux AUR
    by BeauHD on 16/06/2026 at 4:00 pm

    The Arch Linux User Repository "AUR" is facing another issue just days after more than 1,500 packages were found carrying malware. According to Phoronix, over 70 AUR packages have reportedly been modified to insert Russian spam and profane messages into users' shell configuration files. From the report: Nicolas Boichat with his AI/LLM detection bot detected some questionable messages appearing in AUR content. Russian messages were being added post-install to the bashrc / zshrc / Fish configuration, etc containing offensive messaging. Those commits happened on the 14th, after the recent malware fiasco. And then over the past day reporting on dozens of AUR packages having similar Russian messages containing offensive language. The latest update on that thread indicates more than 70 AUR packages having this Russian spam / offensive messaging. Among those various Python packages, Ruby packages, Llama.cpp, and others. At least the AI/LLM bots are proving helpful here in proactively picking up on some of the AUR abuses until the fundamental situation can be better handled. Read more of this story at Slashdot.

Users can enable JPEG XL in the Firefox Labs panel within Settings. Read more of this story at Slashdot.

  • Venus' Strange Rotation Was Likely Triggered By a High Velocity Moon-Sized Impactor
    by BeauHD on 16/06/2026 at 11:00 am

    New simulations suggest Venus' extremely slow backward rotation may have been triggered by a high-angle collision with a fast-moving object roughly one-tenth its mass. The impact could have dramatically altered Venus' spin and melted nearly its entire mantle. Universe Today reports: Venus' bizarre and extraordinarily slow retrograde rotation on its axis has long puzzled planetary scientists. But in a new paper presented at the recent European Geosciences Union General Assembly in Vienna, the authors argue that their models indicate that a high angle moon-sized, high-velocity impactor likely triggered Venus's strange 248-day rotation. And it probably happened within the first 50 million years of Venus' formation. [...] The team found that an impactor that is about a tenth of Venus' mass hitting the planet at a high angle could drastically slow the early young planet's rotation. Depending on the actual impact parameters, we can slow down a rapidly rotating early Venus to rotation rates that are that are compatible with long-term evolution towards a slow rotating planet, says [Cedric Gillmann, the paper's lead author and a planetary scientist at ETH Zurich]. Or even in some cases with large energetic impact that happen with a tangential impact that would even put planets early on in already a retrograde but faster rotation, he says. In the simulations, giant impacts expectedly produce surface magma oceans, the paper's authors note. Their relative depths vary depending on impact properties: from a shallow melt layer in the order of 100km thick to a fully molten mantle, they note. If the surface can radiate heat to space efficiently, the magma ocean cools down quickly, they write. If Gillmann and colleagues are correct, Venus' likely impactor also melted some 99 percent of Venus' mantle. That is, the interior structure that extends between its core and crust. You will get rid of that impact heat pretty efficiently, and after a few hundred million years, you end up seeing an evolution that is very difficult to distinguish from a case where you don't have an impact, says Gillmann. What role the impact may have played in Venus' lack of plate tectonics, however, remains open for debate. But it's known that Venus' lack of a large-scale carbon recycling mechanism likely led to its current runaway greenhouse. Read more of this story at Slashdot.
