I've built a nice home server OS

ohai! I've released Lightwhale 3, which is possibly the easiest way to self-host Docker containers. It's a free, immutable Linux system purpose-built to live-boot straight into a working Docker Engine, thereby shortcutting the need for installation, configuration, and maintenance. Its simple design makes it easy to learn, and its low memory footprint should make it especially attractive during these times of RAMageddon. If this has piqued your interest, do check it out, along with its easy-to-follow Getting Started guide. In any event, have a nice day! =)

In plain words

Lightwhale 3 is a free, immutable Linux operating system designed for self-hosting Docker containers. It boots directly into a working Docker Engine without requiring installation or configuration, eliminating the need for ongoing maintenance. Built with simplicity and low memory usage in mind, it is intended for users who want an accessible way to run containerized applications on home servers.

Make Linux servers fun again!

is a purpose-built operating system designed to run Docker containers effortlessly. It live-boots from an ISO straight into a fully functional Docker Engine, eliminating the need for installation or configuration. The core system is immutable, making it inherently maintenance-free while enhancing security. Data and customisations are stored entirely segregated on a dedicated device, ensuring they never become entangled with core system files. This gives transparency and makes backup easier. Streamlined yet versatile enough for home labs or enterprise , bare‑metal or virtualized, edge nodes or clusters. Driven by a minimalistic design philosophy and an emphasis on ease of use, Lightwhale…from lightwhale.asklandd.dk

    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…
