  Tin Validate, a tax ID validator that explains why checks pass or failJun 2026 · tin-validate.com · ▲5

  After a year and a half of hard work, we recently released TIN Validate (tin-validate.com), a Tax Identification Number (TIN) validator available through both a web portal and a REST API. Over the past few years, we have seen a significant increase in regulations aimed at strengthening tax compliance and the automatic exchange of tax information. In Europe for example, the DAC7 directive now requires collaborative platforms such as Airbnb and Booking.com to report users' income along with tax information. Financial institutions are also already required to perform international tax reporting…

  Talanoa▲346

  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…

  Trading cards made with e-ink displays▲1,149

  I made a thing! In 2014, I was holding a stack of iPhones and thought to myself: "Hey, if I had each phone display a playing card, I could click a button and they'd shuffle themselves" I pared that idea all the way down to this: trading cards made of e-ink displays. Right now, each card costs me about $20 each, but with only a bit more scale, I think I can get that down to $10. In doing this project, I learned how to design electronics and circuit boards. I learned Rust and wrote my first driver, I upped my CAD skills, 3D printed, and did my first resin casting. I generated the images on the…
