We built BareMetal OS -- an exokernel with sub-millisecond cold boot and hardware level microVM isolation. We think it's small and fast enough to be genuinely interesting to build on. So we're running a 2-week challenge to find out what you can build. See attachment for contest details and rules. Complimentary cloud credits for every applicant to help you build on our servers.
