• Hacker News1Hosting a website on a disposable vapeA programmer salvaged microcontrollers from disposable vapes and successfully created a web server running on one. Using a PUYA PY32F002B chip with 24KB flash and 3KB RAM, they implemented TCP/IP networking through semihosting and SLIP protocol over a debugger connection. Despite the extremely limited hardware specs, the server can host web pages and even includes a JSON API endpoint, demonstrating that even "disposable" electronics contain surprisingly capable computing power.Comment moderation and duplicate handling:Users questioned why HN moderators moved comments from a 4-hour-old post to a newer one by the author. Moderators explained they prioritize original submitters and merged discussions to give the project creator proper credit and karma for their first submission.Website performance under load:The original vape-server website crashed immediately when it hit HN's front page, causing the first submission to fall off early. Users joked about the server "letting out one last valiant puff of smoke" before succumbing to the traffic load.Karma system motivation:Discussion arose about why users chase karma points beyond unlocking initial features, with one user questioning the appeal of continuing to accumulate karma after reaching functional thresholds.
• 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
