📱 Perplexity is in talks to pre-install its browser LINK
  • Perplexity is talking with mobile device makers about pre-installing its new Comet browser on smartphones in an attempt to challenge Google Chrome's market dominance.
  • The Comet browser integrates agentic AI to let people ask questions about personal data like emails and calendars, or perform tasks like scheduling meetings.
  • This strategy targets browser "stickiness" to encourage habitual use, though convincing OEMs to switch the default away from Chrome remains a difficult challenge.
📺 Microsoft suddenly kills its movies and TV store LINK
  • Microsoft has suddenly closed its movies and TV store, preventing new purchases of content on both Xbox consoles and Windows personal computers.
  • Previously purchased movies and shows remain accessible through the Movies & TV app, but the company is not offering any refunds for the owned content.
  • This shutdown was anticipated by users after the Groove Music service was discontinued in 2017, ending a service that started as the Zune Video Marketplace.
🔋 iPhone 17 Air rumored to have a smaller battery LINK
  • The upcoming iPhone 17 Air will reportedly feature a 2,800 mAh battery, a capacity that is smaller than any model expected in the iPhone 16 lineup.
  • This reduced size is a trade-off for the phone’s rumored ultrathin 5.5 mm frame, a design which severely limits the device's available internal space.
  • Apple plans to compensate with a new iOS 26 feature called Adaptive Power Mode, but tests show it may not provide all-day life for many users.
🏆 Man beats AI model in world coding championship LINK
  • Polish programmer Przemysław Dębiak narrowly defeated a custom OpenAI AI model during a 10-hour coding marathon at the AtCoder World Tour Finals 2025 Heuristic contest.
  • AtCoder hosted what may be the first major onsite world championship featuring an AI model competing directly against top human programmers in a "Humans vs AI" exhibition match.
  • The victorious programmer, a former OpenAI employee, was “completely exhausted” and acknowledged on X that this human triumph over the machine has prevailed only “for now.”
🛡️ Microsoft halts China support for Pentagon systems LINK
  • Microsoft has stopped engineers based in China from supporting the Pentagon's cloud systems after a report revealed their involvement in handling critical U.S. defense work.
  • The investigation found that American “digital escorts” who supervised this work often had less technical skill than the foreign engineers they were supposed to be monitoring.
  • Following this exposure, the Department of Defense will begin a full internal review to identify any similar foreign support activity across its other government systems.
👮 Ring reintroduces video sharing with police LINK
  • Ring has partnered with law enforcement technology company Axon, which will once again allow police to request and receive video footage directly from device users.
  • Users receive solicitations via Axon’s digital evidence management system and can decide to share their video, which is then encrypted and added to the case file.
  • This partnership reverses last year's decision to end the "Request for Assistance" feature, moving the solicitation process from the Neighbors app to Axon's system.
