• Hacker News1LinkedIn is searching your browser extensionsMicrosoft's LinkedIn is conducting large-scale corporate espionage by secretly scanning users' computers for installed software without consent or disclosure. The hidden code collects personal data revealing religious beliefs, political opinions, and job search activity of identified individuals, while mapping competitor software usage across companies. LinkedIn deceives EU regulators by providing restricted APIs while expanding surveillance of third-party tools, and shares collected data with external firms including an American-Israeli cybersecurity company.Misleading headline framing:Users debate whether the headline "LinkedIn scans your computer" is misleading since it only scans browser extensions within the browser sandbox, not the entire computer. Some argue this distinction matters for public understanding, while others contend extension scanning still constitutes computer scanning.LinkedIn's justification and anti-scraping measures:LinkedIn defends the practice as necessary to detect extensions that violate terms of service and scrape user data without consent. Discussion centers on whether anti-scraping measures justify privacy invasion and scanning for religious/political extensions.Browser security and Chrome vs Firefox:Technical discussion about why browsers allow extension detection, with Firefox users noting they're protected due to randomized extension IDs while Chrome-based browsers remain vulnerable to this scanning technique.
• 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
