In plain words
This is an open-source Java HTTP server built on non-blocking NIO (New Input/Output) architecture. It is designed for developers who need a lightweight, asynchronous server for handling multiple concurrent connections efficiently. The non-blocking approach allows it to manage high loads without creating threads for each request, making it suitable for performance-sensitive applications. The project is available on GitHub for review and contribution.

Talanoa▲341Hi 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…

Hey HN, I 3d scanned the interior of the Great Pyramid / Khufu's pyramid for the Giza Project this summer and just finished the guided version to share. Would love feedback and/or problems you encounter. I used both a Leica BLK 360 and Matterport Pro 2 to do the scanning and the Matterport SDK for the web viewer. Matterport's web display with Three.js has been the most accessible to a wide audience in the past (previous iterations are in Unity and Unreal, but difficult to download over slower connections). I've been interviewing social studies teachers around the 6th grade level to…

APIs are a little like the open road—always waiting, full of opportunity, but hardly utilized. So here’s America, composed of several APIs that paint a vivid, real-time picture of a good old-fashioned road trip. Get local classifieds and photos. Tune into local radio stations. Talk wit other drivers. And more. Exploring the country by car was an invaluable experience for me during my time in the states. I’ve since moved to Barcelona, and find myself missing the territory. This is my attempt at recreating the magic.
