  Forte, an open-source self-hosted music platform with lots of features2023 · github.com · ▲6

  Hey everyone, I've made a project to make your own music archive streamable and turn it into a complete music platform. The reason I've been working on this project for a while was to stream the CD's I've had at home without any cost and also make a nice looking system to manage and listen to these albums. You can host your own server and use the web player to connect. Also, it is possible to create users and give them access to your own server. Some features of the current release are group sessions, endless listening with radio, fuzzy searches, showing lyrics and specialized context menus.…

  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…

  I got laid off from Meta and created a minor hit on Steam▲1,581

  I was at FB/Meta from late 2013 to early 2023, mostly working in the compiler/runtime spaces. I got hit in the spring 2023 layoff wave. I immediately started making games in my newfound free time (a lifelong interest, and I even worked in AA(A?) back ca. ~2000), and in October 2023 I stumbled upon the idea of a roguelike pachinko/plinko game inspired by Luck Be A Landlord. Things snowballed quickly, I started talking to publishers, then worked like crazy through all of 2024, almost the hardest I've ever worked in my career, and launched the game in December 2024. It's sold…
