FocusedEdit – a classic Macintosh to web browser shared text editor

In plain words

FocusedEdit is a text editor for classic Macintosh computers that enables real-time shared editing with a web browser on modern computers. It allows users to quickly share and edit text snippets between a vintage Mac and contemporary devices. The software runs on 68k and PowerPC Macintoshes from System 2.0 through MacOS 9.2.2, requiring only a modem serial port connection. It is designed for retrocomputing enthusiasts and anyone working with legacy Macintosh systems who need collaborative editing capabilities.

  Talanoa▲340

  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…

  I 3D scanned the interior of the Great Pyramid at Giza▲1,752

  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…

  America – Road Trip Simulator▲663

  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.
