• Hacker News1The <output> TagThe HTML `<output>` element is an underutilized tag that represents calculation results or user action outcomes, automatically announcing changes to screen readers without requiring ARIA attributes. Despite being in the spec since 2008 with excellent browser support, most developers overlook it in favor of divs with ARIA live regions. It works perfectly for calculators, form validation feedback, and dynamic content updates, providing built-in accessibility features that make interfaces more inclusive with less code.Limited adoption and awareness of HTML output tag:Many developers are unaware the "<output>" tag exists despite being part of HTML5 since 2008. The lack of usage creates a feedback loop where it's not taught or implemented, leading to continued obscurity even among experienced developers.Missing features and browser inconsistencies:The "<output>" tag is criticized as "half-baked" with suggestions for type attributes (currency, date, number formatting) similar to input tags. Screen reader support issues require workarounds like "role="status"".Semantic HTML vs pragmatic development:Debate over whether to use semantic HTML tags like "<output>" versus more widely supported solutions. Some argue semantic HTML is a "novice trap" while others advocate for proper accessibility through standard tags.
• 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
