3 weeks, roughly in line with faster Space Shuttle turn around times

The shortest shuttle turnaround time was 55 days. Almost three times as much as Falcon 9. The fastest post-Challenger turnaround time was 88 days, I believe. After Columbia, the fastest turnaround was around 5 months.

NASA claimed that the shuttle could achieve a turnaround time of two weeks (page IX). It looks like SpaceX is not the only one setting unrealistic timelines?

Without UEFI, the boot process is different for each device, requires a custom boot loader, or at least explicit support by the operating system. Is your laptop going to be supported by the distribution you want to use? What about in 5 or 10 years? With UEFI, the boot process is standardized, so it should just work.

Are you sure that it cannot be updated? The GitHub readme sounds like updating Tiny11 Core is impossible (and it also lacks Windows Defender), implying that Tiny 11 can in fact be updated.

Then the editor, all extensions, language servers, etc. are all running as root.
