James Dyson introduced the Dyson CameraJet in Paris, a toothbrush equipped with a 100k pixel macro lens camera and machine learning that detects gaps between teeth in real time. The device uses this data to fire precision jets of mouthrinse into those gaps while also brushing with variable sonic oscillation designed to keep bristles moving against tooth surfaces.
The piece revisits Robert Bridson's 2007 single-page paper, which offers a fast algorithm for placing random points—like trees in a procedurally generated forest—so no two fall closer than a set minimum distance. It contrasts this compact, widely-cited solution with a nearly 1,000-page 2024 proof of the geometric Langlands conjecture, highlighting the range of scales in mathematical work. The algorithm uses a grid and an active-point list to sample points efficiently in an annulus around existing points, avoiding the slowdown of naive rejection sampling.
Dyson has unveiled its first oral care device, the CameraJet toothbrush, which uses an onboard camera scanning teeth 28 times per second to detect debris and spray targeted mouthrinse to clean between them. Priced at $499, it requires a proprietary nonfoaming toothpaste and will launch in September through Sephora, Best Buy and Amazon. Founder James Dyson said the six-year project stemmed from frustration with dental visits rather than any market analysis.
After curl founder Daniel Stenberg ran OpenAI's Codex Security and Anthropic's Mythos against the widely-used curl codebase and got zero findings, AISLE's autonomous AI system produced 29 vulnerability reports. Six of those were validated by curl's security team and assigned CVE identifiers, all rated Low severity, and fixed in the newly released curl 8.22.0.
Nintendo has released a free update for Mario Kart 8 Deluxe tailored to Switch 2 hardware, enabling local split-screen play for up to eight people using original or Switch 2 controllers. The update also brings CameraPlay support for seeing friends via camera during races, shorter loading times, and improved visuals in docked mode.
Microsoft confirmed that starting in October 2026, memory integrity protection built on Virtualization-based Security will be switched on by default for eligible Windows 11 PCs. The feature runs Windows as a guest OS under Hyper-V to isolate the kernel from tampering, but Microsoft has previously acknowledged it can hurt gaming performance. Organizations will retain the ability to disable it, though the default posture is shifting toward security-first.
Writers Alex Chalmers and Rob Wiblin make the case that landfilling waste, when done properly, is frequently cheaper, cleaner, and more environmentally sound than recycling or reusing materials. They point to plastic bags versus cotton totes as a key example: plastic bags require a fraction of the energy to produce and dispose of compared to the water- and energy-intensive process of making reusable cotton alternatives.
A Washington Post-Elon University poll found that more than a quarter of Americans use AI chatbots like ChatGPT or Gemini for emotional or personal support, with many saying they consider these tools friends or a way to feel less alone. Apple executives Craig Federighi and Greg Joswiak previously said Siri AI is deliberately built to avoid this kind of engagement-driven, sycophantic behavior seen in rival chatbots.
LWN, the Linux and open-source news site that has run on a reader-subscription model since 2002, announced its first price increase since early 2022. The new monthly rates rise by about 20%, mirroring US consumer-price inflation over that period, moving to $6, $11, $19 and $55 across its four subscriber tiers. Existing prepaid subscriptions remain valid until they expire, and current monthly subscribers keep the old rate for six more months.
Microsoft Entra now fully supports passkeys as a passwordless authentication method, with both device-bound and synced passkey options reaching general availability. The guide explains how passkeys work using the WebAuthn standard, where a private key stays on the user's device or synced service while a public key is stored in Entra ID.
Norway's digital minister Karianne Tung says the government is exploring rules to regulate camera-enabled wearables like those from Meta and Snap, citing growing privacy concerns. The devices, sometimes dubbed 'pervert glasses' by critics, combine cameras and microphones with AI and could soon add facial recognition capabilities. Tung plans to convene an expert panel to advise on protecting citizens' privacy rights.
Adobe announced that Slack users can now invoke apps like Firefly, Photoshop, Premiere, Acrobat and Illustrator directly through Slack's AI assistant, Slackbot, which interprets requests and calls the right Adobe tool while factoring in conversation context. Separately, more than 70 Adobe tools are being made available through a new Adobe for Slack MCP app. The integration launches first for Slack Business+ and Enterprise+ customers.
