About

Crazierl is an experimental&#x2F;hobby operating system based around BEAM.<p>I&#x27;ve linked the browser based demo; I don’t recommend using a phone; it does work, slowly, on the phones I tested, but it’s very awkward to use. You can share a link with a hashtag with your friends and click the consent checkbox, and it (should) link up into dist and I’ve also included a chat application you can start with chat:start(). (quit chat with &#x2F;quit, or use the shell menu with ctrl-g to switch between shells etc).<p>The browser demo relies on the v86 javascript x86 virtual machine. You can also run Crazierl on a real x86 system, but I’ve had mixed luck on modern systems, it uses some esoteric legacy VGA features and support for that isn’t getting better.<p>Crazierl is fairly limited: 32-bit x86, BIOS boot, only two NIC drivers virtio-net and realtek 8168. But it&#x27;s got enough to become part of an Erlang dist cluster. It also supports SMP, but it’s crashy with high core counts in qemu; there’s almost certainly several concurrency bugs in the kernel. There&#x27;s also a lot of excess tcp debug spew (sorry).<p>Source code is available (Apache) <a href="https:&#x2F;&#x2F;github.com&#x2F;russor&#x2F;crazierl&#x2F;" rel="nofollow">https:&#x2F;&#x2F;github.com&#x2F;russor&#x2F;crazierl&#x2F;</a>

AI Score Reasoning

Crazierl is a technically impressive hobbyist project demonstrating deep systems engineering, but it lacks any commercial foundation, modern hardware support, or market-ready stability. As an experimental Erlang-based OS, it serves as a niche proof-of-concept rather than a viable venture-scale investment opportunity.
