  • nanos

    A kernel designed to run one and only one application in a virtualized environment

    Project mention: Mirage – A programming framework for building type-safe, modular systems | news.ycombinator.com | 2023-11-23

    Unik was just a build tool that utilized other projects like Rump, Mirage, IncludeOS, etc. It's now dead since Solo pivoted a very long time ago to service mesh/api gateways.

    The GoRump port they use was from us and then we realized we needed to code our own from the ground up for many reasons so we wrote https://nanos.org (runs as a go unikernel in GCP).

  • brutal

    🏢 An operating system inspired by brutalist design that combines the ideals of UNIX from the 1970s with modern technology and engineering

    Project mention: GNU/Hurd strikes back: How to use the legendary OS in a (somewhat) practical way | news.ycombinator.com | 2023-08-07

    Even in the noncommercial world, Hurd's gone precisely nowhere. RedoxOS is a toy and had a GUI within a year or so. Brutal got in within two. SerenityOS not only built a GUI but the beginnings of the first greenfield web browser to gain any semblance of modern standards support in the past several decades. Honestly, what's Hurd doing wrong to flounder so hard?
