  I wanted a way to read PDFs at night and not burn my retinas out so I whipped together this super simple website with Claude to solve my problem. It uses Mozilla's pdf.js library to load and render a PDF and then inverts the colors with CSS. It has basic controls like zoom in, zoom out, reset zoom, previous and next page. There are some keyboard shortcuts that you can find by toggling the "q" key.

  Hi HN, I’m a fullstack developer, and honestly, I’ve lost count of how many side projects I’ve worked on over the years. But one idea kept coming back to me: a different kind of email client. It first came to me in 2014: “What if we could handle emails more like conversations?” Every year, I’d revisit this concept in my “Build Notes.” Ten years later, no one had built exactly what I had in mind — so I finally decided to do it myself. That’s how Talanoa was born. I wanted something focused on people, not timelines. I was tired of marking messages as unread just to remember to reply later, or…
