Jsn – A relaxed, user-friendly JSON-like data format

In plain words

Jsn is a data format that simplifies JSON by making it more relaxed and user-friendly. It maintains JSON-like structure and functionality while removing some of its strict syntax requirements, making it easier to write and read. The format is designed for developers and anyone working with data files who finds standard JSON syntax cumbersome. It launched in 2019 and the source code is available on GitHub.

  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.

  After years of solo development I'm presenting: Angeldust, an omni-compatible action RPG and building game! Website: http://angeldu.st My single server hosts 250+K active players in one giant, dynamic fantasy world. Angeldust's game server is pervasively multithreaded, implementing John Carmack's dream of processing an immutable world state each tick. Both world handling and network traffic routing uses any number of threads. For networking, a typical game session only uses ~3Kbps of bandwidth, enabling decent play even over 2G/EDGE networks. The client is programmed in C++…
