    Discontinued The seL4 microkernel

  • Yes, especially 'logically impossible' when you dig into the details. From the blogpost:

    > and the kernel modifications to seL4 that can reclaim the memory used by the rootserver.

    MMMMMMMMMMMkkkkkk. So you then have to ask: were these changes also formally verified? There's a metric ton of kernel changes here: https://github.com/AmbiML/sparrow-kernel/commits/sparrow but I don't see a fork of https://github.com/seL4/l4v anywhere inside AmbiML.

    I mean, it does also claim to be "almost entirely written in Rust", which is true if you ignore almost the entire OS part of the OS (the kernel and the minimal seL4 runtime).

  • WorkOS

    The modern identity platform for B2B SaaS. The APIs are flexible and easy-to-use, supporting authentication, user identity, and complex enterprise features like SSO and SCIM provisioning.

  • camkes-tool

    The main CAmkES tool

  • Those names come from the existing seL4 project that these googlers are merely using/forking.

    (CAmkES is a hot mess, and "unpleasantly too much C" if you ask me. https://docs.sel4.systems/projects/camkes/ & https://github.com/seL4/camkes-tool/blob/master/docs/index.m...)

NOTE: The number of mentions on this list indicates mentions on common posts plus user suggested alternatives. Hence, a higher number means a more popular project.
