• Hacker News1GrapheneOS – Break Free from Google and AppleThe author shares their journey from being deeply embedded in the Apple ecosystem to switching to GrapheneOS, a privacy-focused Android alternative. After experimenting with a Samsung Galaxy Z Fold 6 rental, they discovered GrapheneOS through news about France targeting the secure system. The post details choosing a Google Pixel 9a as hardware, provides step-by-step installation instructions including bootloader unlocking and system flashing, and describes their usage approach with additional user profiles, open-source apps via Obtainium, and Aurora Store for Google Play apps. They emphasize GrapheneOS's security features, sandboxed Google services, and recommend it for privacy-conscious users willing to sacrifice some convenience for enhanced security and control over their mobile experience.Banking app compatibility and security theater:Banks block apps on custom ROMs despite allowing web access, creating security theater. Many banking apps work on GrapheneOS with sandboxed Play Services, though some require workarounds. The real issue is Play Integrity API rather than root detection.App recommendations and daily usage:Users share extensive lists of FOSS alternatives including NewPipe, Organic Maps, Signal, and Aegis. Many run dual phone setups or use profiles to separate work/personal apps. Camera quality and Android Auto functionality work well with proper setup.Hardware limitations and future plans:GrapheneOS only supports Pixel phones due to security requirements, causing issues for users with PWM sensitivity. The project is working with an unnamed OEM for future non-Google hardware, though timeline has been delayed to 2027.
• Reddit science1Using scented products indoors changes the chemistry of the air, producing as much air pollution as car exhaust does outside, according to a new study. Researchers say that breathing in these nanosized particles could have serious health implications.Using scented products indoors, such as flame-free candles and wax melts, can create significant indoor air pollution comparable to car exhaust. Research by Purdue University found these products release nanosized particles that can penetrate deep into lungs and potentially enter the bloodstream, posing serious respiratory health risks.Misleading title scope:Discussion about how study only focused on wax melts but title suggests all scented products, with debate about whether findings could logically extend to other scented itemsHealth concerns from chemist:A chemist's perspective against using scented products leads to sharing of personal health impact stories, from COPD to cancer cases, and debate about necessity of artificial scentsAir purification solutions:Discussion of HEPA filters and other air purification methods as solutions, with debate about effectiveness against different types of pollutants like VOCs and nanoparticles
