• Hacker News1Show HN: Bigwords.page – Turn any screen into a sign. The URL is the appA tool that turns a link into a full-screen sign, timer or message for any device, like holding up a phone at arrivals, showing a TV countdown or displaying a Wi-Fi password. Text auto-fits the screen and supports formatting, slides, countdowns and QR codes, with no account, app or stored data.Similar URL-as-state projects:Many commenters shared their own no-backend tools that store content in the URL, including slide stacks, big-text pages, parameter pages, zstd-compressed file sharing, recipe viewers and word searches. Others noted that data URLs and the older bigassmessage.com do similar things.AI-sounding title debate:Some called "The URL is the app" meaningless LLM-speak and pointed to AI-style phrasing on the site. Others defended the author, citing non-native writers and the lack of evidence. The author said the 80-character title limit forced brevity.Practical uses and improvements:A deaf user plans to use it for communicating, and a panel chair praised the countdown timers. Others discussed cheap digital signage via browser kiosks. Suggestions included the Wake Lock API, downloads for printing and PWA support (since added), plus a Firefox text-fitting bug fix.
• Reddit science1Adults with ADHD often struggle with choices that require weighing potential rewards against negative consequences. A new experiment reveals that a common stimulant medication improves these choices specifically by helping individuals pay more attention to the potential costs of their actions.A placebo-controlled study of 61 adults with ADHD found methylphenidate improved cost-benefit decisions by selectively boosting sensitivity to costs, not rewards. Unmedicated, participants weighed benefits over costs and responded prematurely, unlike healthy controls.Medication as life-changing:Many say stimulants quiet mental noise and enable focus, with stories of dropouts reaching law school or PhDs. Others cite tolerance, side effects, sleep problems and grief over late diagnosis. One user said stimulants worsened their father's judgment, and a reply suggested possible mania.Stimulants as "pharmaceutical meth":A quip comparing ADHD meds to meth sparked debate. Some corrected the chemistry, while others said drugs made them feel "normal" rather than high. One reply cited studies arguing stimulants improve focus in everyone and that dose is the real difference. Addiction risk was also discussed.Decision paralysis and coping strategies:Users described freezing over simple choices like drinks, shoes or video game decisions, calling it analysis paralysis. Many cope by owning identical outfits to remove choices. Several later realized these "quirks" were compensations for undiagnosed ADHD.
